渣浆泵

操作第三讲碱渣泵各位大家好,这次我们要用4个小时的时间来学习碱渣泵。

今天我们既然是来学习的,学习是不是要有一个非常好的状态?一个好的学习状态对我们的学习效果是不是有帮助呢。

大家请看,在韩国LG公司。

(省略500字)。

今天这一堂课的主角不是我,而是在座的每一位,我希望在座的每一位都做一个积极的参与者,而不是做一个旁观者。

今天我在这里,不是让大家来看我讲了多少,讲得多好,而是我讲的内容,你收获了多少,哪一点对你帮助最大。

我也希望在我讲课的过程中,大家能积极的回应我,如果我提问题,所有人都跟木头人一样看着我,那我就不知道你们到底有没有收获,所以希望等一下在我讲课的过程中,大家能多多配合。

好吗?那为了让大家更好的进入状态,我先和大家做一个游戏。

请各位把双手伸出来,我喊123,当我喊到3的时候各位把双手合拢。

听我口令(游戏。

)当我喊到几的时候各位把双手合拢锁紧?为什么我刚刚喊到2的时候,各位就把双手合拢了呢?很简单,因为看到我把手合起来了,所以大家也把手合起来了,是不是?我想跟大家分享一个结论,在沟通过程中大家首先要学会聆听,刚刚我跟大家说听我口令,有没有说看我动作?没有,所以证明大家还没有学会聆听。

我们在座的各位以后在工作中经常要跟领导沟通,同时要跟同事沟通,跟徒弟沟通,所以我们在沟通过程中首先要学会聆听。

可能在我们聆听的过程中会有很多因素在干扰着我们,但是我们不能因为受到干扰而不注意聆听。

我们今天讲课也是一个沟通,所以我们各位今天什么都可以不带,但是至少要带一个器官过来,是什么?对,是耳朵,那刚刚大家的聆听成功了没有?没有,我跟大家的沟通有没有成功?没有,那再来一次,大家有没有信心跟我沟通成功?、、、、、、大家说有还是没有?这个可以有!非常好!沟通成功,听我口令(游戏。

)非常好!大家合起来双手之后先不要动,让我们把双手交叉起来。

看看你们的双手交叉起来之后,是左手大拇指在右手大拇指上边,还是右手大拇指在左手大拇指上边,看完了就先把双手放下来。

广泛用电力、矿山、冶金、煤炭、建材、化工、食品、水利及污水处理等行业。

其固液混合体的最大重量浓度:灰浆为45%,矿浆为60%。

2、本系列泵有50多个基本型号,通过变速可获得300多种性能供用户选择。

3、过流部件材质应根据输送浆体的物理(颗粒组成、粒径、形状、硬度、浓度)和化学(酸、碱、油)特性而定。

(各种材质及特点可通过附录1查得)4、泵的传动方式有直联传动和皮带传动两种形式,共分为DC、HC、CR、CL、ZV、CV等多种方式。

(详见附录3)从原动机方向看,泵为顺时针方向旋转。

二、特点针对渣浆泵的三大技术难题:寿命短、密封难、能耗大,我厂通过技术攻关设计制造了独具特点的ZJA及ZJLA系列两相流渣浆泵。

由于两相流渣浆泵的水利设计充分考虑了固液流场的运动情况,所以在渣浆输送时能保持良好的性能。

其技术特点如下:(1)高效节能:一般的杂质泵输送浆体时,其效率总是下降的,而且浓度越高,粒径越大,降低的幅度也越大。

而二相流渣浆泵输送浆体时,其效率一般高于清水。

这是因为泵的水力设计是以固液二相流场设计的,对清水和渣浆的输送来讲,更适应渣浆的输送。

这一降一升,二相流泵的运行效率提高了3~10%。

所以二相流泵具有新的能量转换规律。

(2)耐磨蚀、使用寿命延长:一般杂质泵输送浆体时,固体发生的主要是撞击磨损,水泵的汽蚀性能随着流量的加大而恶化。

而二相流渣浆泵的流道设计符合固体流场的变化规律,固体沿着叶轮型线运动,叶轮发生的主要是磨擦磨损,泵的汽蚀性能随着流量的加大变化比较平稳,所以二相流泵具有新的磨损规律。

Oil cupFigure 2 The structural drawing of ZJL series vertical slurry pumpsⅢ SLING、INSTALLATION、ADJUSTMENT AND TEST RUN OF PUMPS1. SlingWhen slinging a packed pump, we operate in accordance with marks on the packing case. The packing case shall avoid vibrating violently, overinclining, landing on the body with pointed ends and being placed upside down.When slinging an unpacked pump, we operate according as the following requirement.(1) When lifting the horizontal pump without base or with singly base, the lift gravity is on the side of support square hole that near the pump head. Wirerope pass through this place to join with lift hook. In order to keep the balance of pump, the auxiliary wirerope should be added between inlet pipeline and lifting screw. The lifting screws on support cover and casings are assembled to dismount support cover and casings. They cannot be used when lift the whole pump in case of accident. (2) When slinging the horizontal pump with motor and common base, the lift gravity is on the side of support square hole that near couplings. Wirerope pass through this place to join with lift hook. In order to keep the balance of pump, the auxiliary wirerope should be installed among inlet pipeline, lifting screws on motor and lift hook.(3) The horizontal pump units with intermediate speed-transformation, such as coupled apparatus, should be lift separately.(4) Cushion should be added between wirerope and body of pump to prevent damaging appearance of pump and cutting off wirerope.2. Installation(1) Examination before installationThe pumps have been inspected and tested before ex-factory. Pumps should be set up correctly in order to possess good operating mode. We must check up types of pumps、parameters of pumps and components and parts in accordance with Packing List before installation. We ensure that technical data and quality certificate of pump is complete. Pump can be installed after reading correlation technical data carefully, especially such as THE INSTRUCTIONS OF INSTALLATION AND APPLICATION FOR TYPE ZJ SLURRY PUMPS and mastering related technical requirements.(2) Installation and capturing of pumpThe horizontal pump units should be equipped by making use of twice grouting. The central line of pumps is consistent with the central line of foundation. Thedeviation between center-height of pump and design value is smaller than ±2 mm vertically and 0.1/1000 horizontally.We assure axis of pump units by adjusting couplings when pumps are drove by couplings. There are two methods.The first method is the use of knife ruler and plug gauge. We adjust outside diameter of couplings with knife ruler to guarantee alignment in every direction and the max tolerance (δ) less than 0.1 mm [See Figure3,(a)]. We examine the interval between coupling to guarantee the max tolerance △(△=δ1-δ2) smaller than 0.1mm[See Figure3, (b)]. The other method is the use of plug gauge and magnetic centigrade scale. We fix magnetic centigrade scale on outside diameter of one coupling and put measuring head on outside diameter of the other coupling. The pulsation of centigrade scale should be smaller than 0.15mm [See Figure3, (c)] when turn rotor. We check up the space between couplings with plug gauge to ensure the max tolerance less than 0.1mm [See Figure3, (b)].(a) (b) (c)Figure 3 Capturing of couplingThe shaft of pump and the motor should assured the parallelism when pumps are drove by belts, so we adjust direction on the basis of pulley. When central distance is small, we can align end faces of pulley with ruler; when central distance is big, and we can adjust them by aligning end faces through span wire system [See Figure, (4)].Figure 4 Capturing of belt wheels(3) Configuration and requirement of discharge pipeline and suction pipeline According to the applied condition and the cavitation performance of pump, the arrangement of pump can be classified into exalted setting [See Figure5, (a)] and low setting [See Figure5, ( b)].(a) (b)Figure 5 Arrangement of suction pipeline and discharge pipeline①Suction pipelineDiameter of suction pipeline: diameter of suction pipeline should be equal to pump inlet or larger than it so as to avoid cavitation and deposition of slurry in pipeline. Gate valve of suction pipeline: In order to maintain easily, we should install inlet gate valves whose diameter is equal to the diameter of suction pipeline. The expansion pipe should be set up between inlet of pump and suction pipeline so as to disassemble pump.②Discharge pipelineDiameter of discharge pipeline: diameter of discharge pipeline is usually bigger than outlet of pump because diameter of discharge pipeline is related to properties of slurries and sedimentation flow rate.Gate valve of discharge pipeline: Diameter of outlet gate valve is equal to diameter of discharge pipeline.Piezometer: The piezometer should be set up on the ascending pipe between outlet of pump and the first valve.③Points for configuration of pipelineThe diameter of pipeline is related to system resistance, critical sedimentation velocity of slurry etc. Before inlet of pump, one-stage pipe longer than 3 times diameter of pipeline had better be installed. The velocity of slurry is between 1.5 and 3.0 m/s, which is determined by critical sedimentation velocity of slurry.When we install suction pipe in suction arrangement we adopt pipe of varying diameter whose upper generating line is horizontal to avoid cavitation (See Figure, 6).Figure 6 Reducing pipe with horizontal upper generating lineWhen we adjust the capacity of pump with throttle, throttle should be installed on the discharge pipeline. When throttle is fixed on suction pipeline, cavity will happen easily.(4) Pipelines of water-sealing and water-coolingPacking seal will be equipped with stubs and piezometer. We must install pressure gauge on shaft seal water pipeline to adjust the pressure of shaft seal water. The setting of shaft seal water pipeline and water-cooling pipeline are seen Figure7.Shaft seal water Water-coolingFigure 7 Arrangement of shaft seal water pipelineThe pressure of shaft seal water should be computed according as the following formula.Table 1 Pressure and Capacity of shaft seal waterNote: This Table is suitable to single stage pump.When the suction pressure of pump is 0 (Pin=0), the pressure of shaft seal water is equal to the half of the pressure of pump exit (P’=1/2P out).The pressure of water-cooling is between 0.05~0.2MPa, the capacity is between 1~3 m3/h.The type of water-cooling see Table 2.Table 2 Type of Packing, water-sealing and water-cooling(5)Packing selectionAsbestos packing with mica should be often used when the working pressure of pump is less than 0.5MPa and asbestos packing with ploytetrafluoroethylene should be used when the pressure is more than 0.5 MPa. The type of packing see Table 2. The packing standard should be accord with stuffing box size, and from the direction of shaft, joints of the adjacent packing rings included 120°.3. Adjustment of pumpWe examine and adjust pumps after assembly.(1) Adjustment of the interval between impeller and front liner (See Following)(2) Adjustment of rotation direction of motorMotor's direction of rotation must be in accordance with pump's direction of rotation. When pump operate in opposite direction, some parts will be damaged. After pumps are divorced from motors completely, we can regulate motor direction of rotation. When they are in the same direction, we attach pumps to motors. We must not start motor blindly.(3) Adjustment of transmissionWhen pumps are drove by elastic pin coupling, protective cover and pins should be set up carefully. When pumps are drove by belt, we adjust sliding track so as that every belt has the same pretightening force and install protective cover attentively. When pumps are drove by speed controllers, they are adjusted according to installation instructions.(4)All of fasteners must be reinforced again.(5) Put the tools and the lumbers aside to avoid accident, which was set on pump units4. Test run of pumpsPump sets can be tested run after adjustment. If possible, slurry can be transported after test run with clear water.(1) Starting of pump①Before starting of pump we must turn the impeller around in the stated direction in order that whether running is flexible.②Switch on shaft seal water. Adjust pressure up to specified value.③Suction valves are opened completely.④Open water-flooding valves to pour the water into pump.⑤Open the outlet valves and adjust the opening degree of valve gate to quarter.⑥Start the pump units. We turn on piezometer on discharge pipeline after speed of rotation was stable. If pressure of discharge pipeline was stable, we can open discharge valves slowly up to required working conditions.Attention:When discharge valves are opened fully, starting pumps will make motor overloaded. Opening suction valves partly will bring about cavity.(2) Notes of pumpAfter operation of pumps normally, we should examine the followingof work condition.②Examine whether the electric current of motor is stable.③Examine sound、noise and vibration in pump units is normal or not.④The temperature rise of bearings is under 35℃, but the highest temperature of bearings is lower than 75℃.⑤For packing seal, should open the shaft sealing water and check whether shaft sealing water quantity and water pressure are suitable, adjust the bolts on packing gland so as to adjust packing and shaft sealing water, it is better to leak out drop by drop, if packing is very tight, heating will be produced on the bearing consuming power, if packing is very loose, amount of liquid leakage will be excessive large.(4) Shutting down①Pumping clear water on pump for 30 minutes before shutting down in order to clear any slurry through pump.②Shut off discharge valves.③Close the water of shaft seal and water-cooling.④Shut off suction valves.Attention: we must stop each stage pump at the same time when discharge valves are opened fully, lest water hammer happen and parts will be damaged.Ⅳ COMMON FAILURE AND HANDING MEASURENO.1(1) Appearance of faultyThere is no water in pipeline when pumps operated normally.

According to the feature of the ZJ series pumps, we establish the requirement of maintenance. When the pump is working, must ensure that the packing are installed.1. MaintenanceThe ZJ series pumps have been adjusted before delivery. During 6 months after purchasing customers need not take apart pumps. Before using pumps, we should examine the flexibility of rotation and add lubricant oil.⑪Keep facilities clean、dry、without dirties and leakage.⑫Examine oil level in support every day, its deviation from the oil level of support is ±2 mm⑬Examine operation、vibration and leakage every day. We must solve them in time when we find problems.⑭No operating when pump-out. When operating on that condition, pumps will vibrate violently and reduce service life.⑮Metal body and big block, which cannot pass through pumps, must not enter pumps, neither do rubbers, plastics, and cottons, lest wet parts are damaged and stopped up so as to operate abnormally.⑯We should check up flow and pressure of shaft seal water and cooling waterand oil by examining position of valves and taking their temperature of stuff box. Higher temperature shows short of water.⑰Examine leakage of shaft seal water regularly. When leakage becomes big we should adjust bolts of stuff cover and exchange stuff in time.⑱Assembly of the packing①The packing length should be accord with sleeve circle, and from the direction of shaft, joints of the adjacent packing rings crossed 120°.②After packing, test run with supplying water, meantime, adjust gland bolts carefully to make the leakage be drop not line. Packing is very important to be pay attention to, it not only related state of seal, but also affect performances of pump.⑲In order to make pumps operate efficiently we must adjust the interval between impeller and front liner so as that it is between 0.75-1.00 mm. The interval has been adjusted before delivery. You can stop pump and adjust it if you find it isn't up to mustard or you find problem in pump's work. Adjust them as following.①Undo nuts of support cover.②Undo adjustable bolt screws.③Tighten nuts of bearing box averagely so as that rotor moves to pump head until rotor cannot rotate. Attention: direction of winding impellers should be in accordance with work direction.④Measure the interval (δ=a) between flange of bearing box and end face of support. Now the interval between impeller and front line is zero.⑤Undo nuts of bearing box.⑥Tighten adjustable screws averagely so as that rotor moves to motor. Check up the interval until it is equal to a+(0.75-1.00mm). Attention: ensure the rotor stated firmly.⑦Tighten nuts of bearing box in order to fix rotor in axial direction.⑳Examine temperature of bearings and ensure it lower than 75℃.⑴Exchange lubricating oil after pumps operate for 800 hours running.⑵Auxiliary pumps rotate the quarter circle weekly so as that shaft of pumps bears static load and vibration of base evenly.⑶If auxiliary pumps are not operating for a long time, we should clean sediment with water before running pumps.⑷Examine supporting mechanism of pipeline regularly so as that supporting is reliable and body of pump does not bear supporting force.⑸Examine fastening parts of base frequently in order that fasting is reliable.⑹Pins can be set up after testing rotor direction of rotation for pumps assembledwhen pumps are drove by belts. Pumps must not rotate oppositely. When motors are loss of power, slurry in pipeline can make impellers rotate oppositely. But when head of pump is above 80m, we should prevent slurry from flowing back lest pumps rotate oppositely.⑺Before starting pumps, we should switch on shaft seal water and cooling water. After stop pumps for 15 minutes, we switch off shaft seal water and cooling water. 2. Assembly、dismantlement and examinationAll elements and parts should be checked up and washed before assembly. We examine if all elements and parts are fit for requirement. After exchanging damaged parts, we assemble pumps.Sequence and requirement of assembling(1) Assembly of rotor partsBearings in the ZJ series Slurry pumps are made in China generally. And the system of lubrication applies to oil.①Assembling of bearinga. Use qualified bearings.b. Examine depth of parallelism and degree of roughness of inner diameter、outer diameter、width and two end faces. Check up flexibility of rotation、rust、stain and so on.c. We should check up the endplay to angle joint bearing and double self-aligning bearings. After we find the center of ball track, we determine whether to add washer and what deep the washer is to guarantee the standard endplay of bearings. Don't assemble radial thrust bearing contrarily.d. When we assemble separable bearings, we should set up them according to marks of inner rings and outer rings in order to avoid assembling them improperly.e. For bearings that can be installed in double direction, we should make the end with marks outward so as to recognize.②Assembly of shafta. To avoid occlusion of seating and damaging axle holes, we should smear oil on seating before installation.b. We install bearings by using hot-pack method. We put bearings into oil into heating apparatus to immerse all seating into oil. We heat the oil to 80-100℃. We should install thermometer in oil to control temperature. After installation, bearings should be cooled down naturally to avoid damaging elements and deforming elements.c. After installing back bearing, we assemble the baffle sleeves and knuckle nuts tod. After examining whether bearings lean on shaft shoulder and whether bearings rotate flexibly. After that, assemble bearing box as hot-pack method.e. Assemble front bearings last as above.f. Fix the seal rings on bearing box.g. After parts of shaft and support are installed, assemble other parts as assembly drawing.⑫Assembly of supportAbove all, clear support cover 、support body’s oil pool and bearing hole.①After we clean the seating between support cover and support body we add paper washer to guarantee bearing holes fit for tolerance of ±0.015mm.②We assemble hexagonal plug screw and oil scale-plate. We scratch a line through the center of oil scale-plate and smear red paint to express oil level.③Assemble cooling parts and cooling cavity covers (Note: Some pumps are not equipped with cooling cavity covers.).④Assembly of parts of shaft and supportLift shaft and put parts of shaft into seating of support. Lift support cover to close support after swearing glue on paper washer. Interval between inner end face of bearing box and end face support is 3mm. We set up taper pin and tighten bolts in advance.⑤Set up oil seal in front bearing cover. After add washer between front bearing cover and end face support, we can tighten bolts.⑥After we examine the interval between back bearing cover and bearing box, we can repair depth of covers and add cushion to let bearing cover leave on the bearing closely. We install oil seal in back bearing cover and tighten bolts after adding cushion between back bearing cover and end face of support.⑦Assemble wash plate and discharge ring. Before assembling discharged ring and pressing wash plate tightly, we should fill grease into screw hole.⑧Assemble adjustable nuts and adapter screw bearing box.⑨Magnetic centigrade scale is equipped with shaft so as to measure coaxality and perpendicularity between locating hole and end faces、shaft center of gyration. The tolerance is smaller than 0.25mm.⑩Assemble coupling or pulley.(3) Assembly of rear casing and rear liner plate①Assemble rear casing on the support.②Assemble sleeve within seal rubber ring on the shaft, then assemble packing gland and water-seal ring on sleeve.。

该系列产品具有结构合理、效率高、寿命长、可靠性高、维修方便、运行费用低等显著优点,广泛用于电力、冶金、矿山、煤炭、建材、化工等工业部门输送含有磨蚀或腐蚀性的渣浆,特别适用于电厂灰渣输送。

泵型号意义:例如:多级串联(3-4)级(1、2级无标记)系列代号高扬程渣浆泵吐出口直径(mm)2.结构说明ZGB(P)系列渣浆泵结构相似,均为卧式、单级、单吸、悬臂双泵壳离心式,其结构特点分泵头部分、轴封部分、传动部分作分别说明。

2.1泵头部分ZGB(P)系列渣浆泵为双泵壳结构,即泵体、泵盖带有可更换的耐磨金属内衬(包括护套、护板等),如图1和图2所示。

泵体、泵盖根据工作压力采用灰铸铁或球墨铸铁制造。

该系列泵均为垂直中开式,吐出口方向可按450间隔八个角度旋转安装。

叶轮前后盖板设有付叶轮以减少泄漏及提高泵的使用寿命。

该系列进口均为水平方向,从传动端看泵为顺时针旋转。

起动及运转时,严禁电机反方向旋转。

否则,将使泵叶轮脱落造成事故。

2.2 轴封部分轴封有两种型式:(1) 付叶轮加填料组合式密封:该种密封型式是我厂采用可靠性设计研制的高性能密封,它使轴封的泄漏减少到了最小。

针对某些不允许稀释、不允许加轴封水的特殊工况(单级)也能正常工作,并达到无任何泄漏的效果。

付叶轮、减压盖、轴套均采用耐磨材料制造,维修量少、使用寿命长,使整机平均无故障工作时间MTBF大大提高。

(2) 机械密封:该形式的密封特别适用于多级串联渣浆泵的密封,完全无泄漏。

凡串联渣浆泵二级及二级以上,建议采用高压轴封水的机械密封,单级采用付叶轮加填料组合式密封。

2.3轴封水压对于单级(或串联一级)采用填料加付叶轮组合式密封,轴封水压力一般不低于0.2Mpa。

对于多级串联采用填料加付叶轮组合式密封,二级和二级以上轴封水压力一般为:n-1第n 级轴封水最低压力=∑ Hi + 0.7Hn, 其中n≥2i=1对采用机械密封,各级泵的轴封水压力一般要求比泵出口压力大0.1Mpa。

各种轴封型式的轴封水量见表1。

表1:轴封水参数表2.4传动部分ZGB(P)系列渣浆泵均采用同一系列的传动部分——托架。

泵轴直径大,刚性好,悬臂短,在恶劣的工况下,不会弯曲和振动。

本系列产品的托架均采用稀油润滑,轴承直接安装于水平中开的托架内,拆检、调整方便、并设有水冷系统,改善了轴承的工作条件,使轴承运行在较低的温度下,大大提高了轴承的寿命。

3.装配3.1轴承组件装配装配时预热轴承,油温不允许超过120℃对于轴承间隙,产品在出厂前已作了调整,一般在0.2-0.5mm之间。

用户在拆装检修或更换轴承时请注意:为保证轴承间隙,应在轴承压盖与托架体(或轴承套)之间加模造纸垫对轴承间隙进行调整,以保证轴承间隙在0.2-0.5mm 之间。

托架体上配有油标,油位应始终保持在油标的中间位置,润滑油一般为20#、30#或40#机械油。

3.2付叶轮加填料组合式密封的组装付叶轮加填料组合式密封包括付叶轮、减压盖、轴套、填料、水封环和填料压盖等。

组装时需要注意各“O”型密封圈的位置必须安装正确。

该组件图如图3所示。

3.3机械密封安装安装机械密封,清洁度至关重要。

安装前,除了将机械密封零件清洗干净外,还应将密封腔端面及内孔壁、轴和轴套表面擦洗干净,检查有无毛刺、损伤等,并及时处理。

特别是机械密封动、静环密封断面应用脱脂棉或档次较高的卫生纸仔细擦洗干净。

确保无划伤或擦伤,并在其上涂一层清洁的机油,保证密封端面在安装贴合之前后高度清洁、否则将会影响密封效果。

机械密封零件系精密机件,装配时严禁强行敲打。

特别是动、静环密封端面精度较高,应倍加保护、不允许磕碰划伤。

为了便于装配,可在橡胶"O"形圈及其相关零件的部位上涂一层清洁的机油或润滑脂。

具体装配顺序如下:(1)将“O" 型圈和长轴套装在泵轴上(如带有挡垫,应先将挡垫顶住叶轮拆卸环端面)。

(2)将静环组合件装在轴套上。

(3)将动环和“O”型圈装在泵轴上。

(4)将四氟水封环装在密封箱最里端。

(5)将密封箱装在泵体上。

(6)将“O”型圈与短轴套装在泵轴上。

(7)在泵的后护板、叶轮及泵盖安装完毕后,将静环与动环两端面贴合。

此时检查静环组合件的压盖内端面与密封箱端面之间的间隙尺寸是否满足要求。

如果不符,可调节泵轴的轴向位置,以确保压盖压紧时弹簧作用力处于最佳的工作状态。

该组件图如图4所示。

(8)压盖压紧之前,用清洁水冲洗密封箱腔体,以保证静、动环两端面无任何脏物。

然后将压盖压紧,请注意压盖上的轴封水接口方向朝上。

3.4 泵头部分组装首先在轴上装拆卸环、轴套、期间需要安装相应“O” 型圈,接着吊装泵体,将泵体用螺栓紧固在托架上:安装机械密封组件(至待调节间隙、待压紧状态)或者减压盖、密封胶垫:吊装后护板,用螺栓紧固在泵体上;放叶轮“O” 型圈,吊装叶轮、护套、用螺栓及固定压板将护套压在泵体上;在泵盖部分装上密封垫、前护板、再合装泵体、泵盖;然后紧固泵盖螺柱,注意泵盖螺柱应对称拧紧。

另外,在装配时应当注意各密封垫必须放在正确位置上并保证压紧。

该系列泵带有拆卸环,拆卸环上的三个内六角螺栓必须用黄油封住,以防锈蚀。

拆卸时应先拆卸其上的三个内六角螺栓,将其拧入拆卸环上的另三个螺孔中,从轴上顶起拆卸环的三个环块,然后才能松开叶轮。

4.运转4.1 起动起动前按下列步骤检查整个机组:(1)泵应安放在牢固的基础上,以承受泵的全部重量,以及拧紧全部的脚螺栓,以防振动。

(2)管路和阀门应加支撑,不得把管路及阀门重量压在泵上。

(3)对于填料加付叶轮组合式密封式或填料密封式渣浆泵,用手按泵转动方向转动轴,轴应能带动叶轮转动,不应有摩擦,否则应调整叶轮间隙(对于机械密封式渣浆泵,在机械密封安装正确的情况下,叶轮间隙一般不再作调整)。

该系列泵随着工作压力的不同,托架型式也有所不同,如图5、图6所示两种结构,现逐一介绍其叶轮间的调整方法。

图5所示托架的叶轮间隙调整方式为:叶轮向后调整时,打开调整孔盖3,松开调整螺母2,拧调整螺母1,间隙达到要求后,拧紧调整螺母1和2,装上调整孔盖3;向反方向调整时,松螺母1,拧螺母2即可。

图6所示托架的叶轮间隙调整方式为:叶轮向前调整时,松开调整螺钉1,拧压紧螺钉2,使间隙达到所需要求;向反方向调整时,松开压紧螺钉2,拧调整螺钉1,间隙达到所需要求后,在拧紧压紧螺钉2。

(4)脱开电联器,开动电机,检查电机转动方向,应保证泵轴按泵体上所标记的箭头方向转动,严禁电机带泵反转,否则叶轮将脱落而造成事故。

(5)直联传动时,泵轴和电机轴应精确对中,以免引起振动和磨损。

(6)在泵的吸入管处装一段可拆卸的短管或伸缩节,其长度应足以拆开泵盖和更换易损件,以便于泵的检修。

(7)对于付叶轮加填料组合式密封,应检查填料处泄漏量:起动前,先打开轴封水,如果泄露量过大,应拧紧填料螺母,直至泄漏成点滴状为止。

开泵后,如果泄露量不大,且填料发热,可适当松开压盖螺母;如果填料继续发热,则停泵,使之冷却,调整压盖螺母,放松填料,使泄漏量稍增大,重新开泵,待填料与轴套跑合后,再调整压盖螺母,减少泄漏量。

(8)对于机械密封,在泵起动前,应检查机械密封是否安装正确:将机械密封的接口连通轴封水管路(新安装的轴封水管路应事先将残存在管路内的焊渣、泥沙等杂物清理或清洗干净),起动轴封泵,打开轴封水管路阀门,人工转动泵轴,如有滴漏现象说明密封端面有赃物存在,应将压盖螺栓松开用清洁水冲洗后,再将压盖压紧。

检查无泄漏,表明安装正确。

起动轴封泵,轴封水压力应比浆泵工作压力高出0.1Mpa以上,待轴封水进入密封箱腔体五分钟后,再起动渣浆泵。

(9)泵在抽送渣浆前,在可能的情况下用清水起动。

4.2 运转(1)运转中定期检查轴封水的压力和流量。

对于付叶轮加填料组合式密封,应及时调整填料压盖的松紧并定期更换填料,以保证始终有少量的清洁水通过轴。

对于机械密封式渣浆泵,不允许在无轴封水或轴封水压不足的状态下运行。

(2)定期检查托架的使用情况,定期检查润滑油的清洁度和油位。

为预防轴承过热,托架备有内外两组冷却系统,必要时可加冷却水。

预留的冷却水接口、冷却水压力参考表1。

4.3停泵停泵前尽可能使泵抽送一段时间清水,以清洗流经泵的渣浆,然后依次关闭泵、泵门、轴封水。

对于采用机械密封的渣浆泵,停泵五分钟后再停轴封水。

5.维护保养为使泵安全经济地运行,应注意日常的维护。

维护保养请注意以下几个方面:5.1轴封的维护定期检测轴封水压和水量。

对于付叶轮加添料组合式密封,要求始终保持少量清水沿轴流过,定期调整填料压盖的松紧并定期更换填料;对于机械密封,要确保高压轴封水的供给。

轴封水压、水量应符合要求。

(如2.3所述)5.2叶轮的调整为使泵合理运行,对于付叶轮填料组合密封式渣浆泵,应及时调整叶轮的轴向间隙。

一般地,对付叶轮加添料密封型式的泵,叶轮向前调整有利于泵性能,向后调整可增强轴封效果,故用户可根据实际需要调整。

调整叶轮间隙时应首先停泵,然后按前述叶轮调整方法进行即可。

5.3轴承润滑定期检查托架中轴承和润滑油的情况,一般采用20#、30#或40#机械润滑油。

在首次运转300小时后换油。

正常运装后,轴承温度小于500℃时,建议每运转3000小时换一次油;轴承温度大于50℃时,建议每运转2000小时换一次油。

用户可以根据实际情况确定换油周期。
