Clean water centrifugal pump. 200- Inlet diameter. 150- outlet diameter. 315- nominal diameter of impeller. These are specifications, and under these specifications, there are generally three sets of parameters. There are three sets of variable values for flow rate and pressure under the premise of nominal impeller cutting, but they are all the same when equipped with motors.

Start stop and operation of the centrifugal pump for clean water:

1) Before connecting the machine, it should be determined whether the direction of the motor is correct and whether the operation of the pump is flexible.

2) Close the idle valve on the discharge pipeline.

3) Fill the pump with water or use a vacuum pump to draw water.

4) Connect the power supply, gradually open the gate valve on the discharge pipeline when the pump reaches normal speed, and adjust it to the required working condition. With the gate valve on the discharge pipeline closed, the pump should not work continuously for more than 3 minutes.

stop

1) Gradually close the gate valve on the discharge pipeline and cut off the power supply.

2) If the temperature is below 0 ℃, the water in the pump should be drained to prevent freezing and cracking.

3) If the pump is not used for a long time, it should be disassembled, cleaned, oiled, packaged and stored.

operate

1. During driving and operation, pay attention to observing the instrument readings, bearing and packing leaks, and whether the vibration and noise are normal. If any abnormal situations are found, they should be dealt with immediately.

2. The bearing temperature shall not exceed 80 ℃, and the bearing temperature shall not exceed 40 ℃ higher than the surrounding temperature.

3). The filling is normal, and the leakage should be small and even?.

4). The bearing oil level should be kept at the normal position, and should not be too high or too low. If it is too low, the oil should be replenished in a timely manner.

5). If the clearance wear between the sealing ring and the impeller is too large, a new sealing ring should be replaced.
