Precautions in the use of pipeline centrifugal pump:

1. During the entire operation of the pipeline centrifugal pump, the temperature of the rolling bearing shall not exceed the natural ambient temperature 3. The maximum temperature shall not exceed 80.

2. Add rolling bearing lubrication automobile oil in the rolling bearing body of the pipeline centrifugal pump. Observe the amount of oil at the bottom shaft of the oil standard, and immediately replace or add grease.

3. Unscrew the plug of the diversion channel of the centrifugal pump casing of the pipeline, and grout (or grouting) the diversion channel.

4. Close the cut-off valve, outlet pressure gauge and inlet negative pressure gauge of the outlet pipeline of the pipeline centrifugal pump.

5. inching pipeline centrifugal pump motor, free to check whether the motor is normal rotation.

6. Start the pipeline centrifugal pump motor. After everything is normal for the pipeline centrifugal pump, open the outlet barometer and the inlet vacuum pump. After the medium working pressure is displayed, slowly open the shut-off valve and check the load of the motor.

The total flow and head of the centrifugal pump should be controlled within the range indicated on the sign board as much as possible to ensure that the pipeline centrifugal pump runs at the efficiency point, so as to achieve the great practical effect of environmental protection and energy saving.

8. If the pipeline centrifugal pump is found to have abnormal noise, it should be stopped immediately for inspection.

9. When the pipeline centrifugal pump is stopped, close the stop valve and barometer first, and then terminate the motor.

10. Check whether the centrifugal pump, pipes and joints are loose.

11. Regularly maintain the damage of the pipeline centrifugal pump coupling, and replace it immediately after the damage is large.

12. When the pipeline centrifugal pump is used in severe winter, the water plug at the bottom of the pump shell should be opened to clean the material after parking to avoid freezing.

　　13.pipeline centrifugal pumpWhen not in use for a long time, the pipeline centrifugal pump should be disassembled, dry the water, coat the rotating parts and joints with vegetable oil, and store them properly.

Pipeline centrifugal pump work within a month, 100 hours after the grease should be removed and replaced, after every 500 hours to change the oil.

15. Attention should be paid to adjusting the packing screw cover of the centrifugal pump to ensure that the leakage in the packing room is normal.

　pipeline centrifugal pumpLarge volumes of fluids can be pumped and delivered at a steady flow rate. In general, centrifugal pumps are cost-effective. The structural design of most ordinary centrifugal pumps is usually relatively simple, with only a few components. They are designed to operate at the same performance without much maintenance. The pumping mechanism of the centrifugal pump is to use the rotating impeller to suck water into the suction port of the pump, and the centrifugal force generated by the rotation of the impeller increases the water pressure. The pressurized water is then discharged through the pump housing and the outlet valve. The disadvantage of using a centrifugal pump is that it needs to be filled before use (or the suction port must have a certain immersion depth). This means that you need to provide input fluid before running the pump. Centrifugal pump without medium can not idle.

How to store, transport and anti-corrosion measures for high-lift deep well pumps For well pumps containing packed wooden boxes, they should be placed on a flat concrete floor. For deep well pumps without packed wooden boxes, they should be discharged flat on the pump rack with 3 support points. Both sides shall not be suspended in the air for more than 1m.
