Pipeline pump which points to use?

Pipeline pump is pressurized transmission pipeline to solve pipeline pressure is too low and developed a new pump, horizontal centrifugal pump than the current application has more advantages. Its main points of use are: 1 test work: check whether the connector is loose; hand crank the coupling to make the rotor turn several 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 (the first time), slightly open the outlet valve, start the motor, the pressure rise and confirm the pump group is running steadily outlet valve to the working conditions. 3 running inspection: Pipeline pump in the frequency (frequency) normal operation, should regularly check and record the pump group ammeter, voltmeter, import and export vacuum gauge, pressure gauge and flow meter and other instrumentation readings. Unit vibration, noise, temperature rise is normal. Shaft seals should not have significant aviation fuel leaks.
