Pump industry suppliers - Long shaft submerged pump maintenance regularly?

long shaft submerged pump maintenance regularly?

1, examine various sealing point have run, run, drip, leak condition;

2, check the machine equipment have abnormal vibration or noise; Check the coupling cooling circulation water pipe is unobstructed;

3, check the working pressure, and traffic and everywhere temperature is normal, and make records; Often check everywhere have link anchor bolt loose condition or vibrations caused by loose;

4, often check the packing, stuffing leaked beyond demanded an immediate conversion.

long shaft submerged pump power flow on the high side is what problem?

1, the first to consider whether the model selection is not correct. Model selection is not correct pump did not operate under good working conditions, high efficiency energy-saving, electrical flow up.

2, the motor rated power: divides two kind of situation, the motor rated power of relativity small shaft power, at least 1, 2 times the shaft power. The second situation, applied the non-national standard motor, the output power is not enough.

3, switch power supply system is not stable. The impeller is binding. Motor bearing oil or less bad.

long shaft submerged pump in the condition of the long shaft submerged pump noise small, source of noise is not large also, so feel shock absorption equipment installed in the pump, can reduce noise idea is not correct.

processing long shaft submerged pump operation with the problem of noise, there are several point countermeasures: pump housing with a soft joint connection and water supply pipeline, with support plate extension line with metope touch area, with ductility blinding wall pipe installation.

why leave unused for long shaft submerged pump does not allow the key reason the following:

1, long shaft submerged pump can not be high speed, due to the long axis of magnetic cylinder submerged pump is composed of refrigeration material, if gas will cause magnetic cylinder lock.

2, long shaft submerged pump most of the rolling bearing in the motor rotor is made of carbide cutting tools, made RunHua matter, the pump can't RunHua.

3, long shaft submerged pump are key components of the magnetic components and magnetic components. If high speed, the key components to demagnetization at high temperatures and the characteristics of long shaft submerged pump will reduce the demagnetization.
