| 2017 is a new year, is a year full of hope, some foreign entrepreneurs will look into the Chinese, the rapid development of economy China, pipeline pump (such as vertical pipe pump, centrifugal pump etc.) plays a role in more and more big, a problem, the loss will not say but the language. How to minimize the damage to the case, the correct use of the pipeline pump is the key. Key points of pipeline pump: 1, test: check the connection is loose; the rotor rotation circle dynamic coupling disc by hand, crew rotation is flexible, whether there is noise and weight unevenness feeling, to determine whether the foreign body or the pump shaft is bent, the seal installation is not correct; check the seal cavity clean 20 lubricating oil is filled with 1/2 cavity space; pump unit surface is clean; the steering unit no-load test. 2, manual start: filling pump (for the first time), slightly open the outlet valve, start the motor, the pressure rise and confirm the pump group is running smoothly when the valve is open to the operating requirements. 3, operation check: Pump in power frequency (frequency conversion) normal operation, should be regularly check and record the pump current meter, voltmeter, import and export vacuum gauge, pressure gauge and flow meter readings. Unit vibration, noise, temperature rise is normal. The seal at the fuel leakage should not be obvious. 4, normal shutdown: close the discharge valve, so that the pump light load, stop motor. 5, emergency parking situation: The pump (such as vertical pipe pump, centrifugal pump etc.) the motor current meter indicates the exception (too large or very little); the pump system sends out unusual noise. The vacuum pump inlet pressure gauge, pressure gauge instructions export abnormal vibration pump body and a different sound of a larger, serious decline in performance. The odor, seal oil leakage of air, bearing temperature more than 75 degrees of pump motor. The correct use of the pipeline pump (such as vertical pipe pump, centrifugal pump etc.) can reduce the damage to the machine, but the machine has the problems of time, then time is everything, as far as possible to shorten the machine maintenance time. How to do that? 1, every 500 hours of operation, should release the sealing plug seat, out of residual oil cavity with a syringe; added to the sealed cavity qualified 20 mechanical oil to the cavity half of the volume (add the appropriate method: the oil quantity of running pumps, oil can not smoke outside); plug tight to prevent leakage occurred. 2, found that the mechanical noise of the motor and the temperature rise at the bearing abnormal, should check the motor bearing lubrication. Such as grease discoloration, dirty should be replaced in a timely manner. 3, when there is leakage sealing seat, you can release the sealed plug seat, running pumps, oil field and aviation fuel smoke flavor can be determined: mechanical seal failure. Stop the use of the pipeline pump for quick replacement of mechanical seals. 4, replace the mechanical seal failure |
