Fault Treatment of Hot Water Submersible Pumps

1. Hot water submersible pumps operation occurs vibration
1. Unstable pipe support, pump base or anchor bolts loose is a common cause of vibration, you must tighten the bolts around to avoid loosening.
2. Gas inside the liquid, carefully check the water pump and water inlet sealing surface of the connecting bolts are loose, the gasket is damaged, pump and piping system components have been damaged.
3. Hot water pump and the motor shaft is not concentric, should be adjusted with the belt rotation, the rotation belt too loose or bad contact, can also cause vibration. Impeller impeller is not running in the impeller wear or impeller flow channel blockage can easily cause vibration, sometimes because of the axis of bending impeller impaired balance caused by vibration.
2. Hot water submersible pumps running noise increases
1. Bearing noise: sound source bearing installation parts, generally with an iron bar or screwdriver to live bearing installation parts, with the ears, for the crash crashed sound.
Motor noise: generally wailing, can only replace the motor.
Cavitation noise: sound source in the pump cavity, crackling crackling sound. Third, the motor hot Chinese pump technology forum
The outer wall of the motor may be hot and may run with super current. The valve may be closed with a small outlet. The motor may be replaced if it is operated within the rated current or the quality of the motor coil.
2 rotating parts friction, frictional resistance increases, it may overheat the motor should be hot to check whether the rotor is flexible.
Motor bearing at the heat, may be bearing oil or damaged, need to repair or replace the bearings.
The operating voltage is too low, check the circuit to adjust the voltage.
