High pressure centrifugal pump, high pressure centrifugal pump operating considerations

In the course of everyday use, the proper use of high pressure centrifugal pumps, in order to guarantee the life of the centrifugal pump and the normal operation, the next will be to do careful interpretation of the high pressure centrifugal pump operating processes.

a, high pressure centrifugal pump start check

1, check the reducer tank, high-pressure pump oil level and emulsion tank water level is on the oil level and water level.

2, check the safety valve, pressure gauge, electric contact pressure gauge, water level indicator, liquid level indicator is sensitive and correct; Pressure gauge, safety valve calibration once a year, the relief valve on a regular basis for exhaust test, adhesion in case the valve core and valve hole plug.

3, check each part of the water pump, all valves, solenoid valves, pipes and so on are in good condition, can not have water, air, oil leakage, check the electrical zero ( Ground) Line is solid and reliable, and stop the pump for more than a week, to measure the main motor insulation are in good condition; Check with hydraulic press signal is correct and reliable.

2, high-pressure centrifugal pump drive pump specification

1, contact preservation, electricians, instrument check whether the equipment is normal.

2, manual disc pump, rotor rotation is flexible.

3, open the cooling water pump valve.

4, lubricating oil is normal.

5, pump imported the connected tower, tank liquid level is normal, prevent the time.

6, open the inlet valve and open the pump body and imported tube net exhaust valve exhaust gas.

7, start the motor, after being normal pressure, to open the outlet valve.

8, observe the pressure, whether the current within the prescribed scope.

9, cryogenic pump start is to first open cooling pump pipeline, when the pump cooling completely rear can start, operation and standby pump cooling pipes are in an open position.

3, high-pressure centrifugal pump stop pump specification

1, slowly closing the pump outlet valve, according to the electric parking twist, stop the pump.

2, close the pump inlet valve and needs, according to actual condition to decide whether to removing the pump body pressure, solution line net.

3, closed cooling water and high pressure sealing water ( Winter should make a small amount of water inside the pipe to prevent freezing) 。

4, but high pressure centrifugal pump pump specification

1, according to the normal driving program will open the standby pump

after 2, sure no problem with the new pump can be inverted pump

3, slowly open the standby pump outlet valve, at the same time slowly closed with the water pump outlet valve

4, adjust the new pump discharge valve until the required flow, shut down the pump outlet valve

5, confirm there is no problem, the new pump stopped the original pump

five, the matters that should be noticed in running in high pressure centrifugal pump

often pay attention to the pressure gauge, the ammeter reading is normal, found the abnormal situation in a timely manner to eliminate should find out the reason.

often with lubricating oil, keep oil within the prescribed scope, regularly check the oil, found that have change should immediately according to the rules of change in time.

often observe the lubricating oil, oil seal and the supply of cooling water. Found this handle in time.

check anchor bolt fastening situation of high pressure centrifugal pump and motor, pump body and pump shaft temperature and the voice of the pump running, etc. , for complicated structure and high degree of automation high pressure centrifugal pump ( Such as shielding pump) Must be in accordance with relevant procedures to start, maintain, and parking, before there is no scientific basis and through experiment, operation may not be changed casually
