Operation inspection: when the pipeline pump operates normally at power frequency (frequency conversion), the readings of ammeter, voltmeter, inlet and outlet vacuum gauge, pressure gauge, flowmeter and other instruments of the pump set shall be regularly checked and recorded. Whether the vibration, noise and temperature rise of the unit are normal. There should be no obvious leakage of aviation oil at the shaft seal.
There are always problems in the operation of the machine, but only good operation and maintenance can ensure the best performance of the machine. In order to ensure the normal oil supply, the normal operation and rapid maintenance of the pipeline pump has become the most important task in the equipment management of the oil depot.
Test run: check whether the connecting piece is loose; rotate the coupling by hand to make the rotor rotate several times to see whether the unit can rotate sensitively, whether there is noise and uneven feeling, so as to judge whether there is any foreign matter or whether the shaft can be bent, whether the seal device is not correct, etc.; check whether the clean 20 smooth oil in the sealing cavity can fill 1 / 2 of the cavity space; whether the surface of the pump unit is clean; whether the unit turns to no-load Test.
