潜水电泵维修时要注意的事项： 1．潜水电泵的拆卸方法要正确： 拆卸前要在前后端盖与机座的合缝处用錾子打上记号。因为电机在出厂时的装配是相当合理的，修理后如不按原样装配，可能会造成稍有误差而引起转轴不太灵活。拆卸时要仔细观察绕组的烧坏程度，初步分析烧坏的原因，要注意轻微的扫膛、滚珠破裂等容易看出的故障。如锈蚀严重，不要硬打硬铳，可采用气焊加热合缝处的方法，边加热边用锤轻打，利用热涨原理用“拉马”或铳子取下。 在拆修潜水电泵点击坏绕组时，要注意保护好铁芯及塑料护圈。如果方法不合适，可能会使铁芯外涨及伤残，电机在通电时可能产生电磁效应而使铁芯振动、绕组自身振动，很容易造成绝缘纸、电磁线的绝缘损坏。拆线方法是用斜口钳从一头端面剪断，另一头用钳子抽出。 2．自制线模要合：嵌线要正确。要嵌好一相后，再嵌另一相，使端部形成“三层平面”，端部必须包扎牢固，防止在装配时划伤。 3．要调整好“限位螺钉”的位置 调整时要认真仔细，做到转子转动自如，并且空载电流为最小是{zj0}状态。然后一定要将锁紧螺母拧紧。 4．接头的防水绝缘要处理好 接头处剥去护套及绝缘层，并xx铜线表面的漆层、氧化层，绞接后锡焊。然后xx掉尖角、毛刺及焊液，用 聚乙烯带半叠包6层，再用绦纶胶粘带半叠包2层，作为机械保护层。 5．潜水电泵电机线圈上绝缘漆方法 电机下完线，定型后要上绝缘漆。正确的上漆方法是：将电机的整个嵌线定子浸在绝缘漆中，历时0．5h取出。而一些修理店通常采用刷子刷的办法在定子上涂绝缘漆，由于绝缘漆有一定粘性，故渗透性、均匀性较差，使得上绝缘漆这一工序达不到规定的质量要求。 6．烘烤浸漆定子的温度和时间要恰当 烘烤定子的目的是烘干所上的绝缘漆和去除定子线圈导线间的水分和潮气。正确的烘烤方法是：将定子放人烘箱(炉)中烘烤，温度升至110～120℃，持续 12h，保温并随烘烤箱(炉)冷却12h(不同季节、不同质量的导线，对温度和时间的要求有差异)。而一些修理店往往在烘烤温度和时间上大打折扎，一般烘烤温度为60～80℃，时间为4～6h，有的甚至不作保温处理，导致定子线圈中的水分和潮气不能驱尽，而使电机的质量达不到要求。 7．加注机械油要注意质量 油浸式电动机修理后，应在其定子、转子所有空隙中加注5号(或10号)新机械油，而一些修理店往往将新、旧机械油混合加注，降低了机械油的质量，影响日后电机的使用。 8．电机绕组对机壳绝缘阻值符合要求 定子注油后绕组对机壳的绝缘电阻(冷态)值，可用500v的电压表测量，应不小于1oomω，而修理户修后的油浸式电动机很少有达到此规定数值的，尤其在多雨潮湿的季节，绝缘电阻低于5m12的情况也屡见不鲜。绝缘电阻值过低，易引发触电事故，绝不能掉以轻心。 9．整体式密封盒要定期检查和修理： 整体式密封盒是潜水电泵的关键密封部件，其技术状态的好坏，将直接影响电动机能否正常运行。潜水电泵运行5mω后，应将其提上地面进行检查。检查方法和要求如下： 从电机下端盖的加油孔放出少量的油，查看 油中是否有水分。如果油中含水量不超过5ml，说明密封正常，可继续使用，以后每月检查一次。如果运转50h后，含水量超过5ml，则应将水放净，将油补够，将加油孑l螺塞拧紧，再运行50h，作第2次检查。若含水量少于5ml，可继续使用，以后每月如上所述检查一次。如果含水量大于5ml，说明密封有问题。若上盖油中有水，说明{dy}对磨块漏水或下部密封胶环损坏；若下盖内油中有水，则是第二对磨块漏水或下部橡胶环损坏。这时，应对漏水的磨块和损坏的橡胶封环进行处理或更换。 对修复后或将更换的整体式密封盒，必须做气压试验，检查是否有漏气现象。若漏气，须重新安装或更换密封盒，并将电机进行烘干或晾干处理。{zh1}，从上、下加油孔将新机油

Submersible pump maintenance to note: 1. Submersible Pump demolition methods to correct: before and after the demolition before the end cover and base of the commissure with a chisel tagged. Because the motor assembly at the factory is quite reasonable, if not as is repaired assembly may result in slightly less flexible shaft caused the error. To carefully observe the demolition of the burned winding degree burn because the preliminary analysis, we should note a slight sweep chamber, the ball is easy to see the fault rupture. Such as corrosion serious, do not hard-hit hard pistol, can be used welding method of commissure heating, heated side edge with a hammer tap, use heating or principle of "Rama" or remove the punch. Click submersible pump in the overhaul bad winding, we should pay attention to protect the core and the plastic retainer. If the method is inappropriate, may make things up and the disabled cores, electrical power may arise in the electromagnetic effect of Er Shi core vibration, winding its vibration, it is likely to cause insulation paper, magnet wire insulation damage. Suture removal method is to use oblique nose pliers cut off from the one end, out the other end with pliers. 2. Self-made line mode to combined: Embedding be correct. To insert a good one phase, then embedded in another phase, to end form a "three-dimensional," a solid end to be wrapped to prevent scratching during assembly. 3. To adjust the good "limit screw" position adjustment serious and detailed, so that the rotor turn freely, and no-load current of the smallest is best. Then be sure to tighten the lock nut. 4. Connector strip joints waterproof insulated properly handle the jacket and insulation layer, and to remove the paint surface copper oxide layer, after the solder splices. Then get rid of sharp corners, burrs and welding fluid, with a half stack with a polyethylene bag 6 layer, and then polyester adhesive tape and a half stack package 2 layer, as mechanical protection layer. 5. Submersible pump motor coil insulation paint method on the motor is finished line, shape and after going to the insulating paint. The painting is correct: the motor immersed in the embedded line of stator insulation paint lasted 0.5h out. Some repair shops brush approach commonly used in the stator insulation coating paint, insulating paint because there is a certain stickiness, so permeability, uniformity is poor, making the insulating paint of this process can not reach the quality requirements. 6. Baking Varnish stator baking temperature and time to properly aim the stator by the drying paint and removing the insulation between the stator coil wire water and moisture. Baking is correct: the stator release the oven (furnace) in the baking, the temperature rose to 110 ~ 120 ℃, continuous 12h, baking heat and with the box (furnace) cooling 12h (in different seasons, different qualities of wire, on Temperature and time requirements are different). Some repair shops are often in the baking temperature and time on the big discount bar, general baking temperature is 60 ~ 80 ℃, time 4 ~ 6h, some even without heat treatment, leading to the stator coils in the water and moisture do not drive , Er Shi quality below standard motor. 7. Filling machine Oil should pay attention to the quality of oil-immersed motor repair, at its stator and rotor filling all the voids in the 5 (or 10) of new lubricating oil, and some repair shops are the new and old oil mixed filling machine reduce the quality of the mechanical oil, affecting the future use of the motor. 8. Motor winding insulation resistance meet the requirements of the case after the stator windings of the chassis oiling the insulation resistance (cold) value, the voltage can be 500v table measurements, should be not less than 1oomω, and repair of household repair it after the oil-immersed motor little value to achieve this requirement, especially in the rainy wet season, insulation resistance of less than 5m12 have become ordinary. Insulation resistance value is too low, easily lead to electric shock, and must not be taken lightly. 9. Integral sealed box to inspect and repair: the overall seal box is the key to sealing Submersible Pump parts, its technical condition is good or bad, will directly affect the normal operation of motor ability. After running 5mω submersible pump, it should be put on the ground to check. Inspection methods and requirements are: Motor fuel from the hole under the cover of a small amount of oil released to see whether there is oil in the water. If the oil in the water content of not more than 5ml, shows sealed properly, can continue to use the future to once a month. 50h if the operation, the water content of more than 5ml, the net should be put water, enough to fill the oil will fuel larvae l Plug tightened, and then run the 50h, for the first two inspections. If the water content of less than 5ml, may continue to use the future to once a month as mentioned above. If the water content is greater than 5ml, shows sealing problems. If the above oil in water, shows the first block on the ground leakage or damage to the lower ring sealant; under the cap if there is water in oil, then the second block on the ground leakage or damage to the lower rubber ring. At this time, grinding blocks and deal with leaking rubber seal ring for damage or replacement processing. After the repair or replacement on the overall seal box, to do pressure tests to check for leakage phenomenon. If the leak shall be re-install or replace the seal box, and motor drying or dry handling. Finally, on the new oil under the oil hole
