Start and stop steps of centrifugal pump single stage

Centrifugal pump single stage can be applied to a variety of working conditions. It is a very useful pump product. However, in normal use, we still need to pay attention to the correct operation method of centrifugal pump single stage. Correct start and stop steps can be avoided. cause unnecessary economic losses.

Now let's briefly talk about the operation steps of centrifugal pump single stage
Start-up steps of centrifugal pump single stage
1. The rotor of the double-suction pump should be gently rotated before starting, and it should be flexible and free from jamming when rotating.
2. The outlet gate valve is closed, and the single-stage double-suction pump is filled with enough water to discharge all the air in the pump.
3. If a vacuum pump or a pressure gauge is installed on the double-suction mid-opening pump, close the cock connected to the mid-opening pump and then start the motor. After the rotation speed is normal, gradually open the gate valve on the discharge pipeline to adjust to the working condition range required by the user. Inside. If the flow rate is too large, the gate valve should be properly adjusted and closed; if the flow rate is too small, the gate valve should be properly opened. When the gate valve is closed, the continuous working time of the double-suction centrifugal pump cannot be higher than 3 minutes.
4. The nut on the packing gland should be tightened, and the liquid should be in the form of drops. Pay attention to the temperature rise at the packing.
Stopping steps of centrifugal pump single stage:
1. When the centrifugal pump single stage stops running, the cock and gate valve of the vacuum gauge or pressure gauge should be closed, and then the motor power should be turned off.
2. If the storage environment is below zero degrees Celsius, the fluid in the centrifugal pump single stage should be drained to prevent the pump body from freezing and cracking.
3. When the pump is stopped for a long time, the parts on the centrifugal pump single stage should be removed, the water should be completely wiped dry, and the surface should be smeared with anti-rust oil for proper preservation.
The above are the start and stop steps of centrifugal pump single stage, I hope it will be helpful to your operation.
