Centrifugal pump should pay attention to what matters?

Centrifugal pump should pay attention to the use of the matter:

First, prepare before starting

1, hand-diverted motor blades, impeller should be no card-grinding phenomenon, flexible rotation.

2, open the inlet valve, open the exhaust valve so that the liquid filled the entire pump chamber, and then close the exhaust valve.

3, hand-crank pump so that the lubricating liquid into the mechanical seal face.

4, move the motor to determine the steering is correct.

Second, start and run

1, fully open the inlet valve, close the valve discharge pipe.

2, turn on the power, when the pump reaches the normal speed, then gradually open the valve on the discharge pipe and adjust to the required conditions.

3, observe the instrument readings, check the shaft seal leakage, the normal mechanical seal leakage, <3 drops / min, check the motor, bearing temperature rise ≤ 70 ℃, if abnormal circumstances should be promptly addressed.

Third, parking

1, gradually close the discharge pipe valve, cut off the power.

2, close the inlet valve.

3, such as the ambient temperature is below 0 ℃, the pump liquid should be depleted, so as to avoid cracking.

4, such as long-term disabled, the pump should be disassembled clean, packaging and custody.
