Operating procedures for measuring pumps

Answer:

First, preparation and inspection before starting1. Check to make sure that the drain line is equipped with a safety valve with the correct set pressure.2. Check the screws for the liquid end parts.

3, discharge pipeline unimpeded.4, the pipeline should meet the positive pressure head, that is, in high flow suction conditions work.5, check the direction of the pump, strictly prohibited reverse.6. Check the oil level in the crankcase compartment. For multi cylinder pumps, check that the oil level has reached the required level.7 、 pump motor static grounding is good, meet the requirements.

start-up1. Adjust the stroke indication to zero by adjusting the nut or handle with the rotary stroke.2 open the outlet valve.3. Open the inlet valve, pump, exhaust from the high point, exhaust from the relief valve, the breather valve.4, point motor, check the operation of the pump.5. Start the motor.6, without pressure on the premise, every 15 minutes to improve the stroke 20%, if there is no pressure, do not substantially improve the stroke.Note: (1) whether the sound or vibration of the pump is abnormal (2), whether the stroke adjustment is automatic or not

Pressurization(1) for the discharge pressure below 2.0MPa, then the pump stroke length should gradually increase, each increase of 20%, to maintain 15 minutes.(2) for the discharge pressure greater than 2.0MPa, you need a special pressure, to ensure that the pump discharge pressure gradually increased, each time for the final row pressure of 20%.(3) when the pressure is not increased, the stroke of the pump is gradually increased by 20% strokes per time.Note (1) when pressure is applied, the pressure gauge should be observed at the side of the loading side (slow motion)(2) check ammeter, forbid overload
