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。

The products are designed and developed by The Pump Technology Corporation, Hydromining Research Institute Tangshan Branch and SHIJIAZHUANG INDUSTORIAL PUMP FACTORY. They are innovative in hydraulic designs, structural designs and materials of castings after integrating congeneric products throughout the world. They have many features: high efficiency, reasonable design, reliable operation, long in service time, easy maintenance, and low running costs and so on. The ZJ series pump’s lead their domestic counterparts in various technical performances, with most of them approaching the advanced world level, and widely used for handling abrasive or corrosive slurries in power, metallurgical, mining, coal, as well as chemical industries. For example, flushing ash in power plants and pumping coal slurry in coal preparation plants. They are suitable for handlingabrasive and corrosive solids-bearing slurry with maximum concentrations of wt.45%(ash) and wt.60%(ore).Ⅱ PATTERN、STRUCTURAL FEATURE OF PUMPSThe ZJ series slurry pumps are single-stage, single-suction, axial-suction and centrifugal slurry pumps. They classified into the horizontal version (ZJ type) and the vertical version (ZJL type).1.

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 liftgravity 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. The deviation 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 centigradescale 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 inletgate 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 thedirection 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 following①Examine whether the capacity and head of pump stable and fit for requirementof 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.⑴Keep facilities clean、dry、without dirties and leakage.⑵Examine oil level in support every day, its deviation from the oil level of support is ±2 mm⑶Examine operation、vibration and leakage every day. We must solve them in time when we find problems.⑷No operating when pump-out. When operating on that condition, pumps will vibrate violently and reduce service life.⑸Metal 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.⑹We should check up flow and pressure of shaft seal water and cooling waterHigher temperature shows short of water.⑺Examine leakage of shaft seal water regularly. When leakage becomes big we should adjust bolts of stuff cover and exchange stuff in time.⑻Assembly 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.⑼In 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.⑽Examine temperature of bearings and ensure it lower than 75℃.⑾Exchange lubricating oil after pumps operate for 800 hours running.⑿Auxiliary pumps rotate the quarter circle weekly so as that shaft of pumps bears static load and vibration of base evenly.⒀If auxiliary pumps are not operating for a long time, we should clean sediment with water before running pumps.⒁Examine supporting mechanism of pipeline regularly so as that supporting is reliable and body of pump does not bear supporting force.⒂Examine fastening parts of base frequently in order that fasting is reliable.⒃Pins can be set up after testing rotor direction of rotation for pumps assembled just now and repaired. Belts can be set up after testing motor direction of rotationloss 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.⒄Before 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 to press bearing.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.⑵Assembly 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.③Assemble stuffing box and seal ring in trough, and expeller seal ring and。
