潜水电泵安装使用中的注意事项潜水电泵是一种机泵合一、潜入水中工作的高效节能提水工具。它体积小、重量轻、结构紧凑，安装使用维修方便。具有性能稳定、连续运行可靠、噪音小的特点，并且不污染水源，环保，抽水效率高，省电、使用寿命长。 1．安装 潜水电泵在安装前首先要符合以下安装条件及安装技术要求：①检查潜水电泵是否符合说明书中规定的使用条件及使用范围。②检查井况包括井深、井水、井径是否与选用的潜水电泵相适应。③检查井孔是否清洁，井水是否浑浊，禁止用潜水电泵洗井式抽活水。④检查井口的基础，安装卡箍的位置是否合适，能否承受整个机组的重量。⑤检查潜水电泵机件是否齐全。⑥检查配置的过载保护装置和起动设备是否与潜水电泵相配套。⑦检查电源要求与水泵铭牌上的标示是否一致。 在安装过程中要注意以下事项： (1)下泵过程中发现卡住现象要转动或搬动输水管，克服卡住点，如各种措施仍不见效，千万不要强行下泵，避免电泵与井卡死或损坏。 (2)安装时每根扬水管的法兰盘处均应放橡胶垫并均匀用力拧紧。 (3)根据水井的流沙、淤泥情况确定泵至井底的深度，切不可将泵埋入淤泥中。泵至井底距离一般不小于3m。 (4)水泵的入水深度应为动水位向下距进水节不少于1～1.5m。 (5)水泵使用扬程不应过低，否则需在井口输水管路上安装闸阀以控制水泵流量的额定流量点，防止因流量过大而使电机超载运转而烧坏。 2．使用 电泵投入正常运行后，为了延长使用寿命，要定期检查电源电压、工作电流和绝缘电阻是否正常，如发现以下情况应立即停机检查并排除故障。 (1)在额定工况下，电源电压低于正常值的10％，电流超过额定电流的20％。 (2)电机对地热态绝缘电阻低于0.5兆欧(一般每周检查一次)。 (3)所有保护装置、电气仪表和起动设备有异常现象。 (4)动水位下降至进水节，造成间歇出水。 (5)潜水电泵剧烈震动或噪音大。 (6)电机温升超过额定值45K时。 (7)熔丝烧毁一相。 (8)扬水管损坏。 3．保养与维修 为了正常安全运行，延长电泵使用寿命，一般情况下，每半年或运行1500h后进行小检一次，检查止推轴承、推力盘和导轴承磨损是否严重，如果磨损严重应及时更换，磨损较轻的应适当调节调整螺栓，以保证电机的轴向窜量合适。检查泵体转动是否均匀，如有卡滞现象则需拆开泵体检查橡胶轴承、叶轮和密封环的磨损情况，如磨损严重应更换零件，重新组装再投入使用。 每年或运行2500h后应进行一次大检查，对所有部件进行清洗、除垢、去锈。检查易损件磨损情况，磨损严重的给予更换。 4．贮存 潜水电泵长期不用时应提出井外，并经过检查清洗、擦净后放在干燥通风的室内保存；打开放水螺栓放完电机腔内存水(冬季更应注意，以免冻坏电机)，将电缆盘起来包扎好。电泵不能在0℃以下的室内；长期不用，机组及管路表面要涂漆或黄油防锈，电泵存放时要立放。 5．安全注意事项 (1)电泵在使用前，电机腔内必须加满清水，严禁缺水运行。 (2)严格按规定扬程、流量的工况范围使用，防止在低扬程、大流量情况下工作使电机超载烧毁。 (3)严禁电泵在无水浸没情况下试运行。 (4)机泵安装使用时，严禁电缆受力，更不允许用电缆从井口提升机泵。 (5)电机反转时不得超过lmin。 (6)配置安全过载、启动保护装置，其保护控制性能必须符合产品安全控制要求，容量必须与电泵配套，严禁超载使用。 (7)电泵在检查维修时，必须先切断电源，然后进入作业。

Submersible Pump Installation for attention unity Submersible Pump is a pump, submersible water, energy conservation and efficient working tool. It is small, light weight, compact structure, installation and maintenance. Is stable, reliable and continuous operation, low noise characteristics, and does not pollute water sources, environmental protection, water pumping, high efficiency, energy saving, long service life. 1. Installation Submersible pump installed before the first meet the following installation conditions and installation of technical requirements: ① submersible pump check whether the instructions specified in the conditions of use and usage. ② check the well conditions, including well depth, well, well diameter and the use of submersible pumps are suited. ③ Check the cleanliness of the borehole and well water is turbid, the ban on wash pit submersible pumps pumping flowing water. ④ Check wellhead basis, the suitability of the location of installation of clamp, can withstand the weight of the whole unit. ⑤ checks are complete submersible pump parts. ⑥ check the configuration of the overload protection device and the starting device is matched with the submersible pump. ⑦ check the power requirements and marked on the pump nameplate are the same. During the installation process should note the following: (1) was found stuck under the pump during the phenomenon of rotating or moving pipes to overcome the stuck point, such as measures not effective, do not force the pump, pump and well to avoid stuck or damaged. (2) installation of each pipe flange Yang Department should put hard rubber and tighten evenly. (3) According to the wells of sand and silt to the bottom of the situation to determine the depth of the pump, the pump must not be buried in the mud. From the pump to the bottom is generally not less than 3m. (4) pump water into the depth of the water level down should be moving away from the inlet section of not less than 1 ~ 1.5m. (5) should not be too low lift pumps, wells or water mains need to install the gate way to control the rated flow capacity of pump points, and prevent overload of electrical current overload and burn operation. 2. Use Pump after running into, in order to prolong life, to regularly check the power supply voltage, operating current and insulation resistance is normal, as found in the following situation should immediately stop inspection and troubleshooting. (1) the rated condition, the power supply voltage lower than the normal value of 10% and the current than the rated current of 20%. (2) motor on the ground thermal insulation resistance less than 0.5 MΩ (typically inspected once a week). (3) All protective devices, electrical instrumentation and starting equipment anomalies. (4) water level dropped to flooded sections, resulting in intermittent water. (5) submersible pump severe vibration or noisy. (6) motor when temperature exceeds rated 45K. (7) The fuse burned down one phase. (8) Jan pipe damage. 3. Maintenance and repair To the normal safe operation, to extend the pump life, in general, every six months or run a small biopsy after 1500h, check the thrust bearing, thrust bearing and guide bearing wear is serious, serious should be replaced if worn, wear light The adjustment screw should be suitably adjusted to ensure that the appropriate amount of electrical axial channeling. Check pump rotation is uniform, if any cable wiring Zexu apart pump check rubber bearings, impeller and sealing ring wear, such as badly worn parts should be replaced, re-assembled and then put into use. After a year or run 2500h inspection should be conducted on all parts cleaning, descaling, to rust. Check consumable wear, severe wear to change. 4. Storage Submersible pump should be made well without long-term foreign and checked clean, wipe the interior dry and ventilated place after the save; open the bolt is done and Electrical Discharge chamber memory of water (in winter should note that in order to avoid frozen and motor), the cable set up and bandaged. Pump can not be below 0 ℃ room; long without the crew and the pipe surface to be painted or butter rust, to stand up when the pump storage. 5. Safety Precautions (1) Pump in use before the motor chamber to fill the water, running water is strictly prohibited. (2) strictly in accordance with the provisions of lift, the scope of traffic conditions used to prevent low head, high flow situation allows the overloaded motor burn. (3) non-water immersion pump in case of trial operation. (4) pumps installed, the forbidden lines in the force, but not allowed to raise pump cable from the wellhead. (5) motor reversal shall not exceed lmin. (6) to configure security overload protection device startup, its protection must comply with product safety control performance control requirements, matching pump capacity must be strictly prohibited to use overloading. (7) pump in the maintenance inspection, you must first cut off the power supply, then operational.
