Pipeline pump use points

Pipeline pump use points 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 if the connecting piece is loose; Turn the rotor by hand to make the coupling rotate for a few revolutions to see whether the rotation of the unit is flexible or not, whether there is a feeling of noise and unevenness to judge whether there is any foreign matter in the pump or whether the shaft is Bending, seal installation is not correct, etc .; check the seal cavity clean No. 20 lube is filled with 1/2 cavity space; pump unit surface is clean; unit to no-load test. 2) manual start: filling pump (first time), slightly open the outlet valve, start the motor, the pressure rise and confirm the smooth operation of the pump group outlet valve to the operating conditions. 3) Operation check: When the pipeline pump is operating normally (frequency conversion), it should periodically check and record the readings of the ammeter, voltmeter, vacuum gauge, pressure gauge and flow meter of the pump set. Unit vibration, noise, temperature rise is normal. Shaft seals should not have significant aviation fuel leaks.
