在传统水泥生产过程中,粉磨电耗占总电耗的6 0 — 7 0 %,粉磨高能耗是水泥工业的老大难问题,严重阻碍着水泥企业经济效益的提升和水泥生产规模的大型化。
在粉磨系统中釆用基于料层粉磨技术的辗压机及配套的集打散、分级、烘干于一体的VXS或VXR选粉机,可与球磨机配合或自成系统组成各种各样的工艺流程,如预粉磨、混合粉磨、半终粉磨及终粉磨等系统。
由于粉磨机理的改变, 车昆压机及其系统工艺技术可使粉磨系统电耗降低20 — 100%,产量提高25-200%;适用于新建厂或老厂改造中的水泥生料或熟料的粉磨系统。
以丰昆压机为代表的料层粉磨技术和配套工艺必将成为新世纪水泥干法生产技术发展的新亮点和新热点。
1. 2工作原理CLF系列辘压机主要由电动机、行星减速器、耗系、机架、扭矩支承、液压加压装置、润滑装置、喂料装置、车昆罩、控制系统等组成,眾压机的两个辘轴分别由电动机经万向联轴器、行星减速机带动。
行星减速机安装在扭矩支承上,与车昆子间用缩紧盘联接。
车昆系分为活动车昆系和固定辘系,两个辘系都安装在机架上, 活动车昆系可在机架导轨上作水平运动,活动车昆系两端共有两个(或四个)平行油缸对辘系的轴承座施加压力,该压力通过车昆系作用在通过两车昆轴间的物料上,使物料被破碎、粉磨,并最终被压成料饼。

辊压机运行过程中,当活动辊两端间隙发生变化,需要调节时,根据控制程序发 出的信号,液压站及组合控制阀块相关控制阀门动作,对液压缸压力进行加压或减压 调节,从而调整活动辊的位置,对活动辊辊隙进行纠偏调整。当活动辊纠偏完成后, 恢复保压运行工况。
组合控制阀块上设置有安全溢流阀,可对液压缸的工作压力进行限制。当液压缸 内压力达到设计最高压力时,组合控制阀块上的多功能阀组动作,可在极短时间内, 将液压缸的工作压力卸压。

CAUTION: DO NOT RUN THE CRIMPER ON AN EXTENSIONCORD AS LOW VOLTAGE CAN DAMAGE THE MOTOR.• Oil level in the D165-T420 pump should be 1-1/2 to 2 inches below the fi ll plug and should be visible in the sight glass window of the pump reservoir• Check to be certain that the shipping plug in the pump reservoir has been replaced with the Oil Fill and Vent Plug shipped with the crimper.• Place any Die Set and the Pressure Plate in the crimper bottom fl ange in the order shown. (A hose and fi tting are not required for a calibration check)• Lubricate the die set as shown in Crimping Instructions.NOTE: FAILURE TO LUBRICATE THE DIE SET AND COMPRESSIONCONE COULD RESULT IN THE DIE SET SEIZING IN THE COMPRESSION CONE .• Slide the Pusher onto the stud on the hydraulic cylinder.• Set the Micrometer at “0”.• Depress and hold the Start/Stop switch on the D165-T420 Series or continue to apply pressure to the D160-T420 Series until the Die set is completely closed and oil pressure has built up in the hydrau-lic cylinder.• For the D165-T420 Series: If the ram extends and shuts off the motor approximately 1 second after the die fi ngers are completely closed and the pump builds pressure (The sound of the pump will change) the crimper is correctly calibrated.• For the D160-T420 Series: If the micro site indicator (white line) is just visible as shown in the il-lustration after the dies are completely closed and pressure has built up in the hydraulic cylinder the crimper is correctly calibrated.• If the above conditions are not met, the crimper must be recalibrated. See calibration instructions on P 10.FOLLOW THESE STEPS BEFORE USING THE CRIMPER FOR THE FIRST TIMEMicro site IndicatorPhoto # 1Photo # 2Grease Point # 1Place a thin layer of CrimpX oil (supplied with crimper) or a high pressure molybdenum high pressure grease on the surface of the bottom fl ange (as shown in photo # 1).Grease Point # 2Before sliding the pressure plate or the notched pressure plate over the correct dies, place a thin layer of CrimpX oil (supplied with crimper) or a high pressure molybdenum high pressure grease on the entire area that dies come in contact with (as shown in photo # 2).If Dies are sticking in the surface of the bottom fl ange: Continue to lubricate / grease as explained above in addition to lubricating each die fi nger individually (as shown in photo # 3).Note: The die fi ngers must be lubricated at both positions that come in contact with the pressure plate and the bottom flange.Make certain that the cone base is clean and lubricated prior to inserting the die set.Select the correct die set for the hose-fi tting combination from the manufacturers speci fication sheet. Lubricate the die fi ngers withCrimpX Oil furnished with the crimper.Place the lubricated die set squarely in the cone base as shown.Align the fi tting in the die set according to the hose and fi tting manufacturers recommendation.Place the Compression Plate over the die set and compress the die set by hand to hold the hose and fi tting in place. See micrometer setting example .Slide the Pusher onto the stud on the ram and press the start stop switch or apply pressure to the D160-T420 series. The crimper will shut off when the crimp cycle is complete.When the crimp is complete in the D160-T420 series, a white indicator line will be visible.Check the fi nal crimp diameter to con fi rm that it is within manufacturers speci fications.Micrometer Setting Example: With a 30mm die and the micrometer set at 3.0mm, the fi nal crimpdiameter will be 33mm (30mm + 3mm)Make certain that the cone base is clean and lubricated prior to inserting the die set.Select the correct die set for the hose-fi tting combination from the manufacturers speci fi cation sheetLubricate the die fi ngers withCrimpX Oil furnished withthe crimper.Check the fi nal crimp diameter to con fi rm that it is withinAlign the fi tting in the die set according to the hose and fi ttingmanufacturers recommendation.Place the Notched Pressure Plate over the dies so that the notched compression plate is covering all 8 die fi ngers (as shown).Place the pusher onto the retaining ringas shown. Once the correct micrometer setting is set press the start/stop switch. (Apply pressure on D160-T420 series).Place the lubricated die set squarely in the cone base as shown. Make sure the split of the die cages is facing the operator (as shown).1. Die split must face operator.2. Notched Pressure Plate needs to cover all 8 die fi ngers.3. Damage can occur to die fi ngers if parts aren’t aligned properly.Wrong AlignmentBroken Die Finger• Insert any die set and the Compression Plate in the cone base as shown. Note: There should not be a fi tting in the die set when checking calibration.• Set the Micro Crimp Adjuster as follows at “0”.• Slide the Pusher onto the stud of the hydraulic ram.• Press and hold the start/stop switch until the crimper shuts off for theD165-T420 or apply pressure to the D160-T420 Series until the die set is completely closed and the white indicator on the Micro Sight button is just visible.• If the D165-T420 motor shuts off in approximately 1 second after the dieset is fully closed or the white line on the Micro Sight button is just visible,the crimper is correctly calibrated.• If the crimper requires recalibration, hold the micrometer barrel with a 5/16 inch open end wrench and rotate the stem either in or out with a 5/32 inch hex key wrench.• Rotating the stem out of the barrel decrease the time required for the pump to shut off.• Recheck calibration.Install (2) 3/8-16 x 1" carriage bolts in front twoholes (as shown in picture # 1). Use 3/8" plasticretaining washer to hold bolt into place.Slide the drawer slightly out to access two rear holes(as shown in picture # 2). Install (2) 3/8-16 x 1" carriagebolts in rear two holes (as shown in picture # 2). Use3/8" plastic retaining washer to hold bolt into place.Place the D105/D165 base plate over the 4screws as shown in picture # 3.Place 3/8" fl at washer, 3/8" locking washer, andthen the 3/8"- 16 nut over the bolt as shown. Tighten each nut with a 9/16" wrench or socket until the nuts are tight as shown in picture # 4.Note: Bolt the D105/D165 crimper drawer assembly /# 1# 3# 4# 2PROBLEM: CRIMPER WILL NOT RUN AT ALL• The white rocker switch is also a circuit breaker. Check to see that the circuit breaker has not been tripped• Check the wall outlet. The crimper comes from the factory wired for a 115 volt single phase circuit. Use of extension cords or outlets with inadequate power can damage the motor . Do not run the crimper from a portable power source.• Check the stop switch mounted to the switch bracket under the Micro-Crimp Adjuster. This is a normally closed switch and if it does not close the crimper will not operate.CAUTION: Do not operate the crimper with this switch jumpered as the pump will not shut off and the bracketscan be damaged.• Check the pneumatically actuated switch in the electrical box mounted on the motor. This switch controls power to the mo-tor and is actuated with air pressure from the pendant switch bulb.PROBLEM: CRIMP DIAMETER TOO LARGE• Incorrect setting of the Micro-Crimp Adjuster. Check crimp specifi cations.(NOTE: All published machine settings are approximate. To correct for slight variances, the gauge settings may need to be adjusted for the specifi c hose, fi tting and size combination.)• Incorrect die being used. Each die has a useable range of approximately 3mm (.120 in) above the closed diameter of the die.The closed diameter is the die size stamped on the die ring.• Check crimper calibration and re-calibrate if required.• Inadequate pump pressure. Check oil level in the pump. It should be 1-1/2 to 2 inches below the fi ll plug and should be showing in the sight glass window. Fill with ISO 46 weight hydraulic oil if required.• Inadequate lubrication of the dies and compression ring causing the pump to work harder than normal to reach the required diameter. Use only the grease shipped with the machine or equivalent.• Inadequate pressure being generated by the pump. This is most likely if the crimper can crimp the smaller size hoses and not the larger hoses. When correctly adjusted, the pump should generate approximately 10,000 psi.Do Not adjust pump to produce in excess of 10,000 psi as damage to components or personal injury may result.• No pressure being generated by the pump. There should be a defi nite change in pitch of the pump as it cycles into high pres-sure mode and begins to “work” harder.PROBLEM: CRIMP DIAMETER TOO SMALL• Incorrect setting of the Micro-Crimp Adjuster. Check crimp specifi cations.( NOTE: All published machine settings are approximate. To correct for slight variances, the gauge settings may be adjusted for the specifi c hose, fi tting and size combination.)• Incorrect die being used (See die range under Crimp Diameter too Large)• Check crimp diameter and re-calibrate if necessaryPROBLEM: DIES STICKING IN COMPRESSION CONE• Inadequate lubrication of the compression cone and die surfaces. Use only the grease shipped with the machine or equivalent.CustomCrimp® “No-Nonsense” Warranty StatementAll CustomCrimp® Products are warranted to be free of defects in workmanship and materials for one year from the date of installation.

它通过电机—油泵组将电能转化为液压能,并由液压阀控制系统的压力、流量、方向,操纵油缸完成设备所需要的各项作业。
二、系统工作原理及说明液压系统由液压泵站、顶升油缸及联接它们的高压管件组成。
较详细的构成见液压系统原理图。
手动换向阀的中位机能是Y,该换向阀处于中位,系统液压执行元件处于浮动状态,当系统与液控单向阀连接可以满足液压定位的不同要求,当换向阀手柄前推或后拉时,顶升油缸活塞杆伸出或缩进,从而实现顶升机构的上升或下降。
在液压系统中小车顶升油缸,经过分流集流阀的控制实现了顶升机构的同步升降;再配合液控单向阀、单向节流阀控制,最终实现油缸均速同步锁紧保压等功能。
溢流阀用于保护系统压力不至于超载,溢流阀出厂时已调好,不必要时,用户不得随意调整。
三、液压系统的使用注意事项1、液压油液压系统使用的液压油推荐使用:南方:N46抗磨液压油或30#液压油。
应注意保护工作油液的清洁度,加油前应通过滤油机(过滤精度100µm)加油,加油口位于油箱上盖板,并装有滤清器,应及时换油,一般情况下,累计工作1200小时应更换一次新油,使用过程中,液面最好位于油窗的中部,应经常拆洗,累计200小时拆洗一次,经多次清洗后、达不到过滤的作用时可更换滤芯。
2、电机的接线电机接线应使电机为顺时针方向旋转(俯视电机风叶应为顺时针方向旋转),若接错,泵不打油,该系统不能工作,且易损坏油泵。
3、系统排气若油缸或管路中混有空气,会出现油缸在顶升、回缩过程中出现爬行或抖动现象,因此在正式运行前需先空运转两次以上。

液压自动涨紧系统使用说明书
![液压自动涨紧系统使用说明书](https://img.taocdn.com/s3/m/3b9ca3b4dd3383c4ba4cd21c.png)
液压自动涨紧系统使用说明书首先检查油泵电机转向,方法是:按一下“电机启动按钮”,“电机运行”指示灯亮,电机运转,此时应仔细观察电机转向是否与要求一致,若不一致应迅速按下“电机停止按钮”使电机停转,然后通过变换电源或电机接线进行调整(调整时应注意一定要先将控制箱进线电源切断以确保安全)电机转向调整好后,将控制箱重新送电并按下“电机启动按钮”使电机运转,电机运转平稳后将液压站上的四个截止阀全部打开,将控制箱上的“油缸回缩开关”打在关的位置,然后慢慢调整调节旋钮1和2,此时压力表1(油泵压力)和压力表2(蓄能器压力)应有压力指示,然后继续调整两个旋钮直至压力表1和2的指示压力一致为止。
随着油泵运转,表1和2压力会逐渐升高,当表1和2的压力升高到190bar时油泵电机自动停止(高压保护)。
此时应仔细检查整个液压站看有无漏油现象,若有应及时处理。
检查完毕,顺时针调整液压站上的减压阀调整螺栓,此时压力表3(油缸压力)有压力指示并逐渐升高,同时张紧油缸活塞杆慢慢升出,压力表2的压力逐渐下降(此时压力表1无压力指示)。
调整过程中,若压力表2的压力降到120bar 以下油泵电机将自动启动补压力,最后压力表3的压力调整在100bar(链条的张紧压力)。
张紧压力调整好后要仔细检查油缸及连接管路,一定要保证无泄漏现象。
捞渣机运行过程中,张紧压力不合适可适当进行调整(顺时针调整减压阀调节螺栓,张紧压力增大;逆时针调整减压阀压力减小)。
捞渣机因检修或其它原因不需张紧链条时可将控制箱上的“油缸回缩开关”打在开的位置,此时油缸会很快回缩到初试位置。
自动张紧系统在正常运行过程中,若因管道泄漏或其他原因使系统压力低于100bar或油缸压力低于40bar时,系统将向渣系统PLC发出“系统压力低”,报警信号,以提醒运行人员及时处理以确保设备运行安全。
自动张紧系统在正常运行过程,若系统压力高于210bar溢流阀将自动打开泄压,以确保整个系统及人身安全。

液压拉紧装置说明书
![液压拉紧装置说明书](https://img.taocdn.com/s3/m/8cde42926f1aff00bfd51e10.png)
液压拉紧装置说明书一、特点1、起动拉紧力和正常运行拉紧力可根据输送机张力的需要任意调节,保证胶带在理想状态下运行,以达到延长胶带使用寿命的目的。
2、响应快,输送机起动时驱动滚筒的分离点胶带会突然伸长松弛,拉紧油缸能立刻收缩油缸,以及时补偿胶带的伸长,使紧边的冲击减小,从而使起动平稳可靠,避免断带事故的发生。
3、改善输送机运行时胶带的动态受力效果。
二、工作原理系统工作时,各元件压力整定值,从高到低依次为溢流阀3(简称W3)、溢流阀13(简称W13)、运行自动补压用电接点压力表上限KP1和下限KP2、压力正常信号KP3用压力继电器,(变送器方式时程序自带比KP2小5KN)。
合上电源开关QF1见电气原理图),电源指示灯H1亮,电控箱开始工作,(这里指远控自动状态—继电器方式\变送器方式),程控启动拉紧(线号13、31长信号闭合)、油泵电机运转,油泵打压,同时运行指示灯H3亮,油泵排出的油液经精过滤器到手动换向阀(阀芯事先处在右位即“拉紧”位),液控单向阀,截止阀(事先已打开)进入油缸的有杆腔(亦称前腔),推动活塞向后移动,拉动张紧小车以张紧输送带。
在此过程中,油缸另外一侧无杆腔(亦称后腔)的回油则经过手动换向阀返回油箱。
当油缸有杆腔一侧油压打到一定值时(通常为6MPA左右即蓄能器皮囊内氮气压力),油泵排出的压力油将进入蓄能器挤压皮囊,并缓慢升高油压。
随着油压的不断升高,当压力升到KP3,给程控发出压力正常信号(线号46、47),同时控制箱压力正常指示灯亮;当压力升到KP1(运行上限)时,电磁阀Y1开始得电切断W13,这时系统压力由W3作安全保护,同时 (变送器时是打压到F启动张力停止打压时)给程控发出允许启动(输送机)信号(线号84、85),允许启动信号保持30秒之后消失,同时电磁阀失电和停止打压。
系统压力由W3卸压至W13的设定值,输送机进入正常运行阶段;由于系统存在泄漏,经过一段时间后,当压力降至KP2(运行下限)时,油泵电机自动启动打压,当压力升到KP1时油泵电机自动停止打压,如此自动反复。

Thissystem is manufactured with top quality components and is engineered using the latesttechnology to provide operating reliability unmatched for years to come.When properly used the system can provide protection from sprayer boom damage, improvesprayer efficiency, and ensure chemicals are applied correctly.Please take the time to read this manual completely before attempting to install the system. Athorough understanding of this manual will ensure that you receive the maximum benefit fromthe system.Your input can help make us better! If you find issues or have suggestions regarding the partslist or the installation procedure, please don’t hesitate to contact us.Every effort has been made to ensure the accuracy of the information contained inthis manual. All parts supplied are selected to specially fit the sprayer to facilitate a complete installation. However, NORAC cannot guarantee all parts fit asintended due to the variations of the sprayer by the manufacturer.Please read this manual in its entirety before attempting installation.2General UC5 System LayoutFigure 1 and Figure 2 illustrate the general layout of the UC5 system components:Figure 1: General UC5 System Layout (Self Propel Type)Figure 2: General UC5 System Layout (Pull Type)3Kit PartsThe following diagrams illustrate the GN01 kit specific parts of the NORAC UC5 system. Interface cables, power cables, hoses and fittings are shown in this manual and may not be included. Cables are available separately from NORAC. Please refer to the UC5 Generic Cable Ordering Guide (P/N: UC5-BC-CABLE-GUIDE) for cable ordering information (available at www.norac.ca).Figure 3: GN01 System Parts* Interface and Power cables must be ordered separately.Figure 4: GN01 Hydraulic Plumbing: Single Acting* Hydraulic hoses and some fittings must be ordered separately.Figure 5: GN01 Hydraulic Plumbing: Double Acting* Hydraulic hoses and some fittings must be ordered separately.3.4List of Parts* For systems purchased BEFORE October 1, 2011, the roll sensor part number is 43740.3.5 Hydraulic Fitting Kit Details (P/N: 44865-34)This fittings kit is designed for either single acting or double acting hydraulics. NotThe use of dielectric grease is not recommended on any NORAC electrical connections.To ensure all stainless steel hardware does not gall or seize apply a light coating of the supplied Permatex Anti-seize grease to all threaded parts upon installation. Permatex Anti-seize lubricant is preferred, but other similar anti-seize products may be used.4Pre-Install ChecklistThe pre-install checklist is necessary to check the existing sprayer functionality before the installation.1.Unfold the sprayer over a flat, unobstructed area (i.e. no power lines…etc.).2.Ensure all boom-fold operations are functional (place a check mark in boxes below).3.Bring engine to field-operational RPM and record below.4.Record the time (seconds) it takes for a full stroke for all boom functions. To ensurerepeatable measurements, take the average of 3 trials.5.Not all sprayers will have the functions listed below in Figure6.Ensure the boom has sufficient travel so it does not contact the ground during these tests.Figure 6: Pre-Install Boom SpeedsFigure 7: Breakaway Bracket Assemblypress the spring and insert it together with the collar into the base.2.Slide the tube through the assembled part.ing the bolt and nut, tighten the collar to the tube with the sensor tube centered.4.Apply a small amount of grease to the rotating surfaces of the bracket.5.2Ultrasonic Sensor Serial Number ArrangementWhen installing the UC5 sensors, start with the smallest serial number on the left-hand side, and proceed to the largest serial number on the right hand side. Each UC5 sensor has a serial number stamped on the sensor housing.Apply a light coating of the supplied Permatex Anti-seize grease to all threaded parts upon installation.Figure 8: Sensor Serial Number Arrangement5.3Ultrasonic Sensor Mounting GuidelinesThe following guidelines will ensure optimal sensor performance and prevent sensor measurement error. These rules should be followed for both the wing sensors and the main lift (middle) sensor.1.In its lowest position, the sensor must be 9 inches (23 cm) or more from the ground (A).2.The centerline of the acoustic cone should be approximately vertical at normal operatingheights (A).3.The bottom of the sensor must be at least 9 inches in front of the spray nozzles and boomstructure (B). (This does not apply for the main lift sensor)4.The bottom of the sensor must be at least 9 inches above the spray nozzles (C).5.Ensure there are no other obstructions with a 12 inch (23 cm) diameter circle projecteddirectly below the sensor (D).Figure 9: Sensor Mounting Guidelines5.4Wing Sensor Installation1.The sensor bracket should be oriented forward (ahead of the boom).2.Typically the best mounting location for the wing sensor brackets will be near the end ofthe boom tips, approximately two feet (60cm) from the end.3.Depending on the boom design, some breakaway sections will lift upwards as they breakback. If the sensor is mounted to this portion of the boom, the system will force the boom downwards towards the ground as the boom folds backwards.4.Mount the NORAC UC5 ultrasonic sensor into the sensor bracket and run the sensorcable through the sensor tube.A problem can arise if a sensor is not mounted correctly. It is possible for the sensor to read off of the boom instead of the ground. This may only become apparent once the control system is switched from soil to crop mode.Also be careful that the sensor bracket does not collide with any other part of the boom when the boom is folded to transport position. If possible, mount the sensor brackets while the booms are folded to ensure they will not cause interference.Figure 10: Sensor Reading Off Boom5.51.should position the sensor approximately in the center of the sprayer, forward of the boom. An example of this mounting is illustrated in Figure 12.2.Mount the ultrasonic sensor to the main lift bracket. Run the sensor cable down the centerof the main lift bracket tube.Figure 12: Example Mounting of the Main Lift BracketAvoid mounting the main lift sensor over or near a wheel-track. Measurements from the wheel-track do not provide an accurate crop height and will cause measurement and control error.Ensure the bracket does not collide with any other part of the sprayer throughout the full range of main lift motion.6Roll Sensor InstallationBefore installing the roll sensors you must determine if your sprayer has a trapeze style, center pivot style or high pendulum style boom. For installation on a trapeze style boom refer to Section 6.2. For installation on a center pivot boom refer to Section 6.3. For installation on a high pendulum boom refer to Section 6.4Figure 13: Trapeze Style BoomFigure 14: Center Pivot BoomFigure 15: High Pendulum Boom6.1Bracket Assembly1.Securely mount the roll sensors to the included roll sensor brackets using the #6 machinescrew and nylon lock-nuts.2.The orientation of the mounted roll sensor to the roll sensor bracket will depend on thebracket mounting. The roll sensor CANbus connector must be pointing towards the right side of the sprayer (when looking from the rear of the sprayer).Figure 16: Mounting Roll Sensor to BracketFigure 17: Roll Sensor Orientation - Connector Facing Right Wing6.2Roll Sensor Mounting Guidelines: Trapeze-Suspended Booms1.When mounting the roll sensors, mount the lowest serial number on the trapeze link(boom frame) and the highest serial number on the trapeze support (chassis). For optimal performance, minimize the distance from the boom frame roll sensor to the pivot point (A) and minimize the vertical distance between the chassis roll sensor and the pivot point (B).Figure 18: Roll Sensor Mounting on a Trapeze Suspended Boom2.Ensure the roll sensors are relatively level when the sprayer boom and chassis are level.3.Both roll sensor cables should be pointing towards the right hand wing of the sprayer.4.Ensure both roll sensors are mounted adequately and that the cables provide enough slackto allow sufficient boom roll.1.When mounting the roll sensors, mount the lowest serial number on the boom frame andthe highest serial number on the chassis (non-pivoting portion of the sprayer). For optimal performance, minimize the distance between the roll sensors (A) and minimize the height from each roll sensor to the pivot point (B).Figure 19: Roll Sensor Mounting on a Center Pivot Suspended Boom2.Ensure the roll sensors are relatively level when the sprayer boom and chassis are level.3.Both roll sensor cables should be pointing towards the right hand wing of the sprayer.4.Ensure both roll sensors are mounted adequately and that the cables provide enough slackto allow sufficient boom roll.5.The chassis roll sensor can also be mounted inverted to minimize the distance between theroll sensors (Figure 20).Figure 20: Inverted Chassis Roll Sensor Mounting on a Center Pivot Suspended Boom1.When mounting the roll sensors, mount the lowest serial number on the boom frame andthe highest serial number on the chassis (non-pivoting portion of the sprayer).Figure 21: Roll Sensor Mounting on a High Pendulum Boom2.Ensure the roll sensors are relatively level when the sprayer boom and chassis are level.3.Both roll sensor cables should be pointing towards the right hand wing of the sprayer.4.Ensure both roll sensors are mounted adequately and that the cables provide enough slackto allow sufficient boom roll.7 Module InstallationAn optional module mounting bracket kit is available for purchase from NORAC. The mounting brackets are compatible with control modules and input modules. One kit is needed per module.7.1Control Module: Self Propel Sprayer1.Refer to Figure 1 and Figure 22.2.Securely mount the control module (E01) inside the sprayer cab using screws, cable ties oroptional brackets.3.Connect the display terminal to the control module using the existing display cable.

The battery cable is ordered separately from this kit and may differ from the diagram above.7.2Control Module: Pull Type Sprayer1.Refer to Figure 2 and Figure 23.2.Refer to the display kit installation manual to determine the best mounting location for thecontrol module (E01).3.Connect the display terminal to the control module using the display CANbus cable. Thiscable must be connected to the end of the control module with only one Deutsch connector.4.Connect the existing power cable to one of the two CANbus connectors on the other endof the control module.5.Route cable C01 from the other CANbus connector towards the rear of the sprayer.Figure 23: Control Module Mounting (Pull Type Sprayer)7.3 Valve Module1. Install the valve module (E02) to the top of the NORAC valve block. Orient the 6-pinFigure 24: Valve Module2. Verify the valve coil connectors are oriented vertically (Figure 25).Figure 25: Align Coils3. Place the valve module between the valve coils. Slide a valve mounting bracket over theconnectors of the valve module and the valve coil connectors. This may require flexing the plastic bracket slightly (Figure 26). 4. Ensure the bracket is pushed over the connectors far enough to allow the clips to engage behind the valve connectors.Figure 26: Valve Module Bracket Installation5. Connect the valve module CANbus to cable C01 from the control module. Route cable C02 from the other CANbus connector to the input module.6. With the valve module securely mounted to the valve block, connect the valve cables (C10),to the valve coils as illustrated in Figure 27. Insert the 2-pin plugs (P01) into the unused 2-pin connectors on the valve module. 7. Connect the temperature probe to the valve block using the supplied 3/8” x 1/2” hex bolt.Figure 27: Valve Module - Valve Coil ConnectionsTank PortLeft Tilt PortsRight Tilt Ports7.4Input ModuleCables C20 and C21 are shown in Figure 28 for informational purposes only. The interface cables are ordered separately from this kit and may differ from the diagram below.1.Install the input module (E03) on the boom near the sprayer valve block. Secure it to theboom using cable ties or optional brackets.2.Connect the free end of the CANbus cable (C02) from the valve module to the inputmodule.3.Insert the 12 pin plug (P02) into the OEM 3 connector on the end of the input module.4.Connect the 12 pin connector on the tilt interface cable (C20) to the Thru 2 connector onthe side of the input module and insert the other connectors on C20 into the tiltFigure 28: Input Module Connections5.Connect the 12 pin connector on the main lift interface cable (C21) to the Thru 1connector on the side of the input module and insert the other connectors on C21 into the main lift connectors on the sprayer valve block.6.If your sprayer has a bypass valve, insert the 2-pin tee connector marked “AUX 1” into thebypass valve connection.7.If your sprayer has a slant (roll) function, insert the 2-pin tee connectors marked “AUX 2”into the slant clockwise connection and insert “AUX 3” into the slant counterclockwise.8Connecting the Sensors to the CANbus1.Route cable C03 from the input module to the 8-way coupler (E11).2.Connect both roll sensors to the 8-way coupler. Fasten the 8-way coupler to the boomwith cable ties.3.Connect the main lift sensor to the 8-way coupler using cable C04 and a 2-way coupler(E12). Cable C04 and item E12 may not be needed if the 8-way coupler is mounted close enough to the main lift sensor.4.Connect two cables (C05) to the 8-way coupler and route along the booms to the wingsensors. Follow existing cables and hoses to be sure the cable will not be pinched or stretched.Figure 29: UC5 Module Locations and Cable Connections5.At the sensor brackets, attach a 2-way coupler with terminator (E20) to the sprayer boom.The 2-way coupler with terminator is the white two way coupler. Plug the sensor and the CANbus cable into the 2-way coupler.9Hydraulic InstallationEnsure all pressure has been bled from the system before disconnecting any lines or fittings. Hydraulic pressure will exist on the wing tilt circuits unless the wings are being supported by other means. You may wish to perform the hydraulic installation with the wings in transport position, resting on the ground or with the tilt cylinders fully extended.Component failure due to oil contamination is not covered under the NORAC UC5 system warranty. It is recommended that a qualified technician perform the hydraulic installation.Before assembling the valve block you must identify if the sprayer tilt cylinders are single acting or double acting. A single acting cylinder will only have one hose running to it, while a double acting cylinder has two hoses routed to it.9.1Valve Assembly: Single Acting1.On a clean surface remove the plastic plugs from the block.2.Install the 6MB-6MJ (F07) fittings into the “P” and “T” ports.

SLD-140水平面连铸机液压系统设计说明书邵阳学院毕业设计,论文~引言液压技术渗透到很多领域,不断在民用工业、在机床、工程机械、冶金机械、塑料机械、农林机械、汽车、船舶等行业得到大幅度的应用和发展,而且发展成为包括传动、控制和检测在内的一门完整的自动化技术。
现今,采用液压传动的程度已成为衡量一个国家工业水平的重要标志之一。
由于要使用原油炼制品来作为传动介质,近代液压传动技术是由19世纪崛起并蓬勃发展的石油工业推动起来的,最早实践成功的液压传动装置是舰船上的炮塔转位器,其后出现了液压六角车床和磨床,一些通用车床到20世纪30年代末才用上了液压传动。
第二次世界大战期间,在一些兵器上用上了功率大,反应快,动作准的液压传动和控制装置,大大提高了兵器的性能,也大大促进了液压技术的发展。
战后,液压技术迅速转、系列化而在向民用,并随着各种标准的不断制订和完善,各类元件的标准化、规格化机械制造,工程机械,材料科学,控制技术,农业机械,汽车制造等行业中推广开来。
由于军事及建设需要的刺激,液压技术日益成熟。
20世纪60年代后,原子能技术,空间技术,计算机技术等的发展再次将液压技术推向前进,使它发展成为包括传动、控制、检测在内的一门完整的自动化技术,在国民经济的各个方面都得到了应用。
如工程机械、数控加工中心、冶金自动线等,液压传动在某些领域内甚至已占有压倒性优势。
液压与气压传动是研究利用有压流体(压力油或压缩空气)作为传动介质来实现各种机械的传动和自动控制的学科。
液压传动与气压传动实现传动和控制的方法基本相同,它们都是利用各种元件组成需要的控制回路,再由若干回路组成能够完成一定控制功能的传动系统来完成能量的传递、转换与控制。
1邵阳学院毕业设计,论文~1 液压传动概述1.1 课题提出的背景和意义我国液压工业发展历程,大致可分为三个阶段,即:20世纪50年代初到60年代初为起步阶段;60~70年代为专业化生产体系成长阶段;80~90年代为快速发展阶段。
CLF140-65辊压机手册讲解

CLF140-65辊压机手册第一章概述辊压机是八十年代中期在国际上发展起来的新型粉碎设备。
以它为主组成的挤压粉磨新工艺在节能方面有着显著的效果,受到国际水泥界的普遍重视,成为发展粉磨工艺的一项新技术。
该机应用高压料层粉碎能耗原理,采用单颗粒粉碎群体化的工作方式。
脆性物料经过高压挤压(该机在压力区的压力约为150Mpa)使物料的粒度迅速减小,0.08mm 的细粉含量达到20~30%,小于2mm 的物料达到70%以上,并且在所有经挤压的物料中在在有大量的裂纹,使物料在下一个工序中粉磨时,所需的能耗大幅度降低。
根据国外有关资料的报导和我们已取得的实际使用经验,采用此设备的粉磨系统比未采用该设备的粉磨系统可增产50~200%,单产电耗可降低20~35%。
并且由于磨辊的磨损小,使得单位磨耗大为降低,同时设备工作的噪音、粉尘等均较小,改善了工人劳动环境,充分显示出其卓越的经济效益和社会效益。
辊压粉碎机的主体是两个相向转动的辊子。
脆性物料由输送设备,送入装有称重传感器的称重仓,而后通过辊压机的进料装置,进入两大小相同,相对转动的辊子之间,由辊子一面将物料拉入辊隙中,一面以其间的高压将物料压成密实的物料饼,最后从辊隙中落下,经出料斗,由输送设备提出。
由下一工序对物料饼作进一步的分散或粉磨。
第二章结构简介辊压粉碎机结构较为复杂,载荷很大,系统、部件较多。
为了更好地使用该设备,必须对其各个部件和每夜和必要的了解。
该设备是由轴系、主机架,进料装置、传动系统、液压系统、润滑系统、辊罩、检测系统组成。
见辊压机总图。
两磨辊分别为固定辊与活动辊,活动辊安装于机架内腔的导轨上,固定辊固装于机架立柱上。
进料装置、液压系统、润滑系统均安装在主机架上。

CLF14065 辊压机液压系统使用说明书
一、概述:
辊压机在运行过程中,物料通过固定辊与活动辊之间时,在两辊的压力作用下而 被挤碎。在物料被压辊挤压的过程中,物料对压辊的反作用力将会使辊压机活动辊产 生回退力,向活动辊上施压并维持固定辊与活动辊之间的辊隙稳定是由液压控制系统 完成的。
对活动辊两端施压,由配置于辊压机本体上的四个液压缸进行,每两个液压缸为 一组,两组液压缸分别置于活动辊两侧,对称装配在端部件上。液压缸施压于活动辊 两侧轴承座上,从而传递到两辊之间的物料上。每组液压缸的压力控制各由一个组合 控制阀块控制,组合控制阀块安装在辊压机活动辊侧端部件上。组合控制阀块主要由 集成块、蓄能器、电磁换向阀、节流阀、单向阀、溢流阀、压力传感器、快速卸荷阀 组及测压接头组成。液压缸内液压油的补充及排泄,均由组合控制阀块上相关液压元 器件进行控制。
3. 液压泵在运行中,如液压站油箱内油温达到 40℃时,应将液压站冷却器供水管路上 冷却水阀门打开,向冷却器供水冷却液压油。
4. 液压站运行一段时间后,当高压过滤器滤芯脏污,滤油压差达到设定值时,安装在 过滤器上的压差发讯器发出报警电气讯号,同时压差发讯器红色栓顶出,应在停机 时更换滤芯。
5. 每组液压缸活塞端压力,由组合控制阀块上的压力传感器进行检测,与安装在辊压 机本体上的位移传感器检测的辊隙,共同实现压力、位移联合检测控制。
组合控制阀块上设置的溢流阀 A、溢流阀 B(见图 21),对液压缸的最高工作压力 进行了限制。当液压缸活塞端压力超过安全溢流阀的设定压力值时,溢流阀开启卸压, 降低液压缸活塞端的压力。
组合控制阀块设置有快速卸压阀(见图 21,电磁换向阀 C),当主控程序发出快速

注意:VG46 为冬季使用的液压油牌号。
三、工作原理:
当液压站油位、油温正常,发出液压站启动备妥信号。启动液压泵,液压站低负荷 运行。当辊压机主控程序发出辊压机启动预备信号后,液压站上电磁换向阀通电,液压 站处于溢流运行状态;设置在辊压机上的组合控制阀块上的电磁换向阀 A(见图 21) 通电换向,向液压缸活塞端内注入液压油,液压缸内压力开始上升,当压力达到设定值 时,向主控程序发出液压系统备妥信号,液压泵转入低负荷运行。
