Hot water submersible pump operation and maintenance and storage

Hot water submersible pump operation and maintenance and storage is very important, but also an excellent way to extend the service life, six months of normal operation suddenly a problem, said the quality of hot water submersible pump not, most of the time we ignore the very small The details, we share the following to maintain a small hot water submersible pump details.
1, Hot water submersible pump operation and maintenance:
(1) hot water submersible pumps should be used within the specified range, hot water submersible pump flow must not be too large. When the scope beyond the provisions, likely to cause hot water submersible pump rotor channeling, ammeter swing, the longer the work will result in a serious pump for bad, on the contrary, the pump flow and not too small, otherwise it will increase the downward axial force, So that the life of the entire unit affected.
(2) 8 hours in operation should be fully checked once, ammeter and gauge instructions are significant changes in the operation, whether there is a voice, the normal working current should not be greater than the motor nameplate on the specified rating.
(3) the operation should always check the safety protection device instrumentation reliability and correctness.
2,Hot water submersible pump overhaul:
   One of the following conditions should be shut down for maintenance:
(1) hot water submersible pump running in the steady operating point, while the current exceeds the specified value or a sudden reduction in traffic.
(2) Insulation resistance is low (in the case of thermal state should not be less than 0.5MΩ).
(3) the unit in the operation of abnormal noise or vibration.
(4) power supply voltage and frequency are not up to the requirements.
3,Hot water submersible pump storage:
(1) hot water submersible pump should be stored within the storage of water, the surface wipe, coated with anti-rust oil.
(2) for the long-term suspension of hot water submersible pumps, to professional and technical personnel under the guidance of open, naturally dry, with the parts coated with rust oil, non-coated with anti-rust paint parts.
(3) Within one week after hanging out the well, the unit should go into the well, unscrew the water hole and water hole of the motor, and put the water into the net.
(4) such as in the winter, hot water submerged pump hanging out of the well is still down to use, release the internal storage of water, storage location overflow of not less than 0 ℃, to prevent residual water within the body to freeze
