High-pressure centrifugal pump operation flow and precautions

In the daily use, the correct use of pumps, pumps can guarantee the service life and normal operation, today, the fluid network Xiao Bian to tell you about high-pressure centrifugal pump specifications are specifically how to behave The next high pressure centrifugal pump to do a detailed explanation of the flow of operations. High-pressure centrifugal pump operating processes and precautions First, the centrifugal pump to pump specifications 1, contact preservation, electrician, instrumentation workers check equipment is normal. 2, manual plate pump, rotor rotation is flexible. 3, open the pump cooling water valve. 4, the oil level is normal. 5, the pump inlet connected tower, kettle liquid level is normal, to prevent taking the time. 6, open the whole import valve, open the pump body and exhaust pipe exhaust pipe row of net gas. 7, start the motor, to be normal pressure, then open the outlet valve. 8, observe the pressure, the current is in the specified range. 9, cryogenic pump start is to first open the cooling pump line, when the pump is completely cooled before starting, running and standby pump cooling lines are turned on. Second, the centrifugal pump to stop pumping specifications 1, slowly close the pump outlet valve, press the parking torque, the pump will stop functioning. 2, close the pump inlet valve, according to the actual situation needs, decide whether to remove the pump pressure, the solution drain. 3, turn off the cooling water and high-pressure sealed water (winter water pipes should be a small amount of water to prevent freezing). Centrifugal pump down pump specifications 1, according to the normal driving procedure will be open standby pump 2, to determine the new pump can be inverted without problems after the pump 3, slowly open the reserve pump outlet valve, at the same time slowing the original pump outlet valve 4, adjust New pump outlet valve until the desired flow, turn off the original pump outlet valve 5, confirm the new pump no problem, stop the original pump Fourth, the high-pressure centrifugal pump should pay attention to the operation Often pay attention to the pressure gauge, ammeter reading is Normal, found that anomalies should be identified in time to eliminate. Often observe the oil standard, so that the amount of oil maintained within the provisions of the regular inspection of oil, found that changes should be promptly replaced by the required grades. Regular observation of lubricants, seals and cooling water supply. Find out the situation is dealt with in time. Often check the high-pressure centrifugal pump and motor anchor bolts fastening, pump body and shaft pump temperature and the sound of pump operation, the structure of a high degree of automation and high pressure centrifugal pump (such as shielded pump) must be related Of the operating procedures for the start, maintenance and parking, in the absence of scientific evidence and before the experiment, shall not change the operation 5, high-pressure centrifugal pump common failure and treatment method.
