Guide to the start - up, operation and maintenance of hot water well submersible pump

Temperature well with submersible pumps, also known as hot water well submersible pumps (hot water deep well pump) in the course of the operation is often due to improper operation, out of this kind of problem, today we hot water submersible pump start-up, operation and maintenance to do some simple guidance , So as not to use the process of the problem.
  Hot water submersible pump start:
  1, the motor is full voltage direct start, should be checked before starting.
  (1) the control circuit wiring is correct and reliable, the protection device is safe and effective.
  (2) the water pump gate valve should not be closed, at least to open to 1/4 to 1/6.
  2, all ready, you can close, start the motor, start within one minute after the gate valve should be adjusted immediately to the normal operation of the required degree of opening.
  3, the motor to start again, the second start should be 10 minutes after the stop, when the need for a third start, the interval of 1 to 2 hours.
  Hot water submersible pump operation and maintenance:
  1, hot water pump should be light after the arrival of light transport, careful disassembly, do not allow the cable to drag the unit.
  2, hot water pump after arrival. For a period of time to install, you should do a good job storage work to prevent dirt into the motor internal.
  3, start the motor, observe the ammeter, voltmeter action and data is normal, whether the three-phase current balance, pump running is smooth, with or without noise or vibration.
  4, running, must be observed every 15 minutes, voltage, current value, three-phase current shall not exceed 1.05 times the rated current value, if more than immediately stop the inspection and repair.
  5. When running, the water temperature monitoring device on the switch control cabinet measures the water temperature at the end of the motor winding. When the temperature measuring device indicates the temperature exceeds the above temperature, the monitoring device should act. When the monitoring device malfunctions, the motor should be cut off.
  6, the insulation resistance measured once a week, each measurement results compared with the previous, if found to gradually reduce or decrease a lot, we must take measures to lift the pump check to avoid short circuit, burn the motor winding, insulation resistance, such as Not less than 10 MΩ can continue to run.
  7, hot water pump In the proper use and storage of the case, the Tianjin Auto Pump three guarantees according to the contract.
  The northern winter approaching, geothermal heating work began, the purchase of hot water submersible pump purchase has been included in the schedule to buy geothermal wells with submersible pump to hold on to consider Tianjin Auto Pump, the strength of technology, practical experience, geothermal wells with diving Pump quality assurance 2 more than the heating period, the quality of self-evident.
