Deep well pumps, fire pumps and submersible pumps can be matched with motors or diesel engines according to the actual requirements of the head and flow parameters. On the one hand, the performance of the motor must match the performance of the water pump, and on the other hand, the quality of the motor must pass the test. The motor of the water pump is the key to starting, so the daily maintenance of the motor is indispensable, and the corresponding inspection work should be done when starting the motor. The general user needs more electric motors. What are the hazards of the motor vibration of the water pump?
The vibration of the motor will shorten the winding insulation and bearing life, and affect the normal lubrication of the sliding bearing. The vibration force promotes the expansion of the insulation gap, causing external dust and moisture to invade it, resulting in a decrease in insulation resistance and an increase in leakage current, and even an insulation breakdown Wait for the accident.
In addition, the vibration of the motor will easily cause the water pipe of the cooler to vibrate, and the welding point will vibrate. At the same time, it will cause damage to the load machinery, reduce the accuracy of the workpiece, cause fatigue of all mechanical parts subject to vibration, and loosen the anchor screws. Or cut off. The vibration of the motor will cause abnormal wear of the carbon brushes and slip rings, and even severe brush fire will burn the collector ring insulation, and the motor will produce a lot of noise. This situation generally occurs in DC motors.
The price of the electric motor that matches the pump is different. It should not be considered that the price of the water pump is low, so do not maintain the pump and the motor. The increased maintenance cost is also a loss, so regular maintenance work should be done.
