Factors affecting the normal operation of submersible pumps
2023-01-06
We are in the process of using submersible pumps, once there are problems such as poor sealing, the product is immersed in water for a long time, even if it is not used, the insulation value will drop, and in serious cases, it can not be used. In general, the main factors affecting the normal operation of submersible pumps are as follows.
(1) leakage problem: submersible pump is characterized by the machine and pump as one, and submerged in water together, so the leakage problem is one of the important factors affecting the normal work of submersible pumps.
(2) Plugging: when the submersible pump is plugged, the stator winding will generate 5-7 times the normal full-load current of the plugging current, if there is no protection, the submersible pump will soon be burned. There are many reasons for the formation of submersible pump blocking, such as impeller jamming, mechanical seal debris stuck shaft, dirt surround, etc.
(3) The power supply voltage is too low or the frequency is too low.
(4) wear and rust: wear will greatly reduce the function of the electric pump, flow, head and power are reduced, the impeller and pump cover rust will also cause blocking. Corrosion of submersible pump parts will not only affect the function of the pump, and will shorten the service life.
(5) cable cracked, broken: cable cracked, broken not only easy to form electrocution incident, and the pump work may be in two-phase operation, not only not out of water and easy to damage the motor.
Therefore, we should pay attention to the above-mentioned issues in the process of use, to avoid affecting the normal work of the equipment. In addition, before using the submersible pump again for a long time, the pump casing should be disassembled and the impeller should be re-started after the disk is moved to avoid rusting of the parts and burning the motor winding.

The three taboos of submersible pumps
Any equipment has a service life. The length of service life is not only related to the quality and performance of the equipment itself, but also related to the specifications of people's use. If we do not use the equipment according to the regular requirements, the service life of the equipment will be shortened. Today will introduce three taboos of submersible pumps.

Reasons for high current during operation of submersible pumps
Submersible pump in operation, if the current is high, then the cause of the problem must be with the pump valve regulation and mechanical failure of the motor are necessarily related, at this time, first do not rush out of the problem, find the cause of the fault, and then in the implementation of the next maintenance plan, let's understand together.

Water pump industry gradually towards standardized development
With the continuous progress of technology, pump products will certainly develop in the direction of intelligence, to be able to monitor parameters such as pressure, flow, temperature and vibration; to be able to assess the pump shaft, bearing and seal condition; to be able to diagnose the cause of failure, etc..
