There is also a problem of the total machine time, but as long as the good use and maintenance can ensure the best performance of the machine, which is to ensure the normal supply, Downhole Motor speed to maintain the normal use and management has become a heavy equipment depot in the heavy task.The use of pipeline pump points:
The test work: Check the connection is loose; hand drive dynamic coupling to the rotor turn a few laps to see the unit rotation is flexible, if uneven sound and light and heavy feeling, to determine whether foreign or pump shaft bending, seals installation is not correct, etc.; inspection seal cavity clean oil is filling 20 1 / 2 cavity space; pump unit surface is clean; unit shift load test.Manual start: irrigation Drill Bit (first time), slightly open the outlet valve, start the motor, pump pressure rise and be recognized as a smooth operation when the outlet valve to gradually open condition requirements.
Run check: pipeline pump frequency (frequency) during normal operation, should regularly check and record the pump ammeter, voltmeter, vacuum gauge the import and export, pressure gauges and flow meters and other meter readings. Unit of vibration, noise, temperature, etc. are normal. Seal at fuel leakage should not be obvious.
The normal parking: Close discharge valve, the pump light load, the motor stopped.
The emergency stop condition:Ammeter indicates abnormal work of the pump motor (too large or becomes too small); pump system is making an unusual noise. Vacuum pump inlet pressure gauge, outlet pressure gauge indicates abnormal, Breakout Unit shock and issued different sound large, severe performance degradation. Pump motor odor, air leakage at the oil seal, bearing temperature exceeds 75 degrees and so on.When the machine is a problem, do not worry, the machine should look at the problems and then quickly and propose solutions.
