The proper use of the pump

- Sep 12, 2017 -

How to use the pump better, how to use the pump to better ensure the life of the pump, the following simple to analyze the use of the method

1, start

(a) Determine whether the direction of rotation of the motor is correct before the pump is connected, whether the pump is rotating (or check the motor when the pump is filled with water, and do not allow the pump to run without water) IMG_2340_

(b) Close the gate valve on the discharge line.

(c) fill the pump with water, or use a vacuum pump to divert water.

(d) turn on the power, when the pump reaches the normal speed, and then gradually open the discharge valve on the valve, and adjust to the required conditions. In the case where the gate valve on the discharge pipe is closed, the pump can be operated continuously for no more than 3 minutes.

2, stop

(a) Gradually close the gate valve on the discharge line and cut off the power supply.

(b) If the ambient temperature is below 0 ° C, the pump water should be released to prevent cracking.

(c) If the use of long-term stop, the pump should be disassembled cleaning oil, packaging custody.

3, running

(a) in the process of driving and running, we must pay attention to observe the instrument readings, bearing temperature rise, filler drip and temperature rise and the pump vibration and noise, etc. are normal, if found abnormal circumstances, should be promptly handled.

(b) bearing temperature and ambient temperature difference is not more than 40 ℃, bearing temperature rise of not more than 80 ℃

(c) The filler should be a small amount of water leakage.

(d) bearing oil level should be maintained in the normal position, not too high or too low, too low should be timely replenishment of oil.

(e) If the gap between the seal ring and the impeller is too large, replace the new sealing ring (the diameter of the new pump is about 0.15 ~ 0.25mm)

(f) should try to make the pump in the nameplate specified performance points (flow, head, etc.) near the operation, so that the pump can be long-term work in the high efficiency area to achieve the greatest energy saving effect.
