水泵六大常见故障及解决方法
Water pump six common faults and Solutions
1无法启动
1 cannot start
首先应检查电源供电情况：接头连接是否牢靠；开关接触是否紧密；保险丝是否熔断；三相供电的是否缺相等。如有断路、接触不良、保险丝熔断、缺相，应查明原因并及时进行修复。其次检查是否是水泵自身的机械故障，常见的原因有：填料太紧或叶轮与泵体之间被杂物卡住而堵塞；泵轴、轴承、减漏环锈住；泵轴严重弯曲等。排除方法：放松填料，疏通引水槽；拆开泵体清除杂物、除锈；拆下泵轴校正或更换新的泵轴。
First of all, the power supply should be checked: whether the connection is secure; whether the switch is close; whether the fuse is blown; whether the three-phase power supply is not equal. In case of open circuit, bad contact, fuse fusing and lack of phase, the cause should be found and repaired in time. Second, check whether the pump itself mechanical failure, the common causes are: too tight packing or impeller and pump body between debris stuck and blocked; pump shaft, bearings, leakage, ring rust, and other serious bending of the pump shaft. Elimination method: loosen packing, dredge sink; take apart pump body, remove sundries and rust; remove the pump shaft, correct or replace the new pump shaft.
2配套动力电动机过热
2, auxiliary power motor overheating
原因有四。一是电源方面的原因：电压偏高或偏低，在特定负载下，若电压变动范围应在额定值的＋10％至－5％之外会造成电动机过热；电源三相电压不对称，电源三相电电压相间不平衡度超过5％，会引绕组过热；缺相运行，经验表明农用电动机被烧毁85%以上是由于缺相运行造成的，应对电动机安装缺相保护装置。二是水泵方面的原因：选用动力不配套，小马拉大车，电动机长时间过载运行，使电动机温度过高；启动过于频繁、定额为短时或断续工作制的电动机连续工作。应限制启动次数，正确选用热保护，按电动机上标定的定额使用。三是电动机本身的原因：接法错误，将△形误接成Y形，使电动机的温度迅速升高；定子绕组有相间短路、匝间短路或局部接地，轻时电动机局部过热，严重时绝缘烧坏；鼠笼转子断条或存在缺陷，电动机运行1至2小时，铁芯温度迅速上升；通风系统发生故障，应检查风扇是否损坏，旋转方向是否正确，通风孔道是否堵塞；轴承磨损、转子偏心扫膛使定转子铁心相擦发出金属撞击声，铁芯温度迅速上升，严重时电动机冒烟，甚至线圈烧毁。四是工作环境方面的原因：电动机绕组受潮或灰尘、油污等附着在绕组上，导致绝
There are four reasons. One is the cause of the power of high or low voltage, under specific load, if the voltage range in the rated value + 10% to - 5% outside the motor will cause overheating; power three-phase voltage asymmetry, power supply voltage and three-phase electric unbalance degree is more than 5%, will lead to winding overheating; phase operation experience shows that farm motor burned more than 85% are caused by phase operation, with installation of motor open phase protection. Two reasons: pump is the power is not complete, small horse cart, motor overload long time operation, the motor temperature is too high; the motor start too often fixed for the short-term or intermittent work system of continuous work. The starting frequency shall be limited and the heat protection shall be properly chosen. The three reason is: the motor connection errors, the triangular error connection into a Y shape, the motor temperature rises rapidly; stator winding interturn short circuit, phase short-circuit or local earthing, light motor overheating, severe burn insulation; squirrel cage rotor bar broken or defective, motor operation 1 to 2 hours, the core temperature increases rapidly; failure of ventilation system, should check whether the fan is damaged, the rotation direction is correct, ventilation channel is blocked; bearing wear, eccentric rotor stator and rotor core make sweeping rub a clang, core temperature rises rapidly, serious motor coil burning smoke, even. The four is the working environment of the reasons: motor winding damp or dust, oil and other attached to the winding, resulting in absolutely
