It is always a problem with the machine, but it can ensure the best performance of the machine as long as it is well used and maintained. In order to ensure the normal oil supply, the normal use and quick maintenance of the pipe pump have become the top priority of the equipment management of the oil depot task. Pipeline pump use points: 1, the test work: check whether the connector is loose; use hand-cranked coupling so that the rotor turns a few times to see if the unit rotation is flexible, whether there is noise and uneven feeling, to determine the pump Whether there is any foreign body or the shaft is bent, the seal is installed incorrectly; Check the seal cavity clean No. 20 is filled with oil within the cavity space of 20; pump unit surface is clean; unit to no-load test. 2, manual start: filling pump (for the first time), slightly open the outlet valve, start the motor, the pressure rises and confirmed as the pump group running steadily outlet valve to the working conditions. 3, the operation of inspection: Pipeline pump in the frequency (frequency) normal operation, it should regularly check and record the pump group ammeter, voltmeter, import and export vacuum gauge, pressure gauge and flow meter and other instruments of reading. Unit vibration, noise, temperature rise is normal. Shaft seals should not have significant aviation fuel leaks. 4, normal parking: close the discharge valve, the pump light load, stop the motor. 5, emergency stop conditions: ⑴ pump motor current meter anomalies (too large or become too small); pump system abnormal sound. ⑵ pump inlet vacuum pressure gauge, outlet pressure gauge indicates an exception, the pump vibration larger and issued a different sound, a serious decline in performance. ⑶ pump motor odor, leakage at the shaft seal aviation fuel, bearing temperature over 75 degrees and so on.
