2019/8/1??????view:

  It is very important to start gear oil pump correctly, otherwise it will damage the pump. Here are some common knowledge before starting. Please pay attention to one.

  Next:

  I. Preparations for starting gear oil pump:

  1. To test whether the motor steering is correct (with the direction indicated on the pump body), the test time should be shorter so as not to cause dry wear and tear of the grinding parts caused by the internal rotation of the pump due to non-liquid lubrication.

  2. Open the exhaust valve to fill the whole pump body with liquid, and close the exhaust valve when it is full.

  3. Check whether all parts are normal.

  4. The high temperature type should be preheated at a rate of 50 C/h in order to ensure uniform heating of the components.

  2. Starting of gear oil pump:

  1. Close the pump outlet valve;

  2. Fully open pump inlet valve;

  3. Start the motor and observe whether the pump is running normally.

  4. Adjust the opening of the outlet valve to the required working conditions. If the user has a flow meter or pressure gauge at the outlet of the pump, the pump should operate at the rated points listed in the performance parameter table by adjusting the opening of the outlet valve. If the user does not have a flow meter or pressure gauge at the outlet of the pump, the motor and electricity of the pump should be measured by adjusting the opening of the outlet valve. Flow, so that the motor in the rated current operation, otherwise will cause the pump overload operation (that is, large current operation, until the motor burned out) adjustable outlet valve opening large and small and pipeline conditions related;

  5. Check the leakage of the shaft seal, and the leakage of the mechanical seal should be less than 3 drops per minute in normal time.

  6. Check the motor, bearing temperature rise is less than 80 C.

  Third, gear oil pump shutdown:

  1. Close the outlet pipe valve;

  2. Cut off the power supply;

  3. Close the inlet pipeline valve;

  4. If the gear oil pump is stopped for a long time, the liquid in the pump should be exhausted.
