The use of the pipeline pump overview point 4)

is the machine always have problems, but as long as the good use machine and maintenance to ensure the best performance, in order to ensure the normal oil supply, the normal use of pipeline pump and rapid maintenance of oil depot equipment management has become a top priority task. Pipeline pump use points:, commissioning work: check whether the fitting is loose; Dish with the hand dynamic coupling rotor revolutions circle, whether turning is flexible, whether there was a noise, and the weight unevenness of feeling, to decide whether pump for foreign body or shaft bending, seal installation is not straight, etc. ; Check if cleaning, lubricating oil seal cavity filling/cavity space; Whether the pump unit surface clean; The unit to no-load test. To start, manual: pump priming ( For the first time, a little open export pneumatic valve, start the motor, pressure rise and make sure the smooth operation for pump group working condition of pneumatic valve to gradually open the export requirements. , pipeline pumps in power frequency run check: Frequency conversion during normal operation, shall regularly check and record the ammeter, voltmeter, import and export pump group vacuum gauge, pressure gauge and flow meter meter readings. The vibration of the unit, such as noise, temperature rise is normal. The place should not have obvious fuel leak of the shaft sealing system. , normal parking: closed discharge pneumatic valve, make the pump light load, motor stalling. Work, emergency parking situation: (1) pump motor ammeter instruction exception ( Too big or become less; The abnormal noise pump system. 2 pump imports also vacuum pressure gauge, pressure gauge indicating abnormal, pump body vibration is larger and different sound, serious decline in performance. Bad breath, (3) pump motor shaft seal leakage of aviation fuel, such as bearing temperature more than degrees.
