How to deal with the failure of the micro vacuum pump?

Micro vacuum pump (that is, small vacuum pump) refers to: it has a suction nozzle and an exhaust nozzle with one inlet and one outlet, and can continuously form a vacuum or negative pressure at the inlet; a slight positive pressure is formed at the exhaust nozzle; the working medium is mainly It is a gas, a compact instrument. So how to deal with the failure of the micro vacuum pump? Let me introduce it to you.

The power supply is faulty Check whether the power is cut off, or the power supply phase is missing
Foreign matter enters the pump, and the impeller is stuck. Rinse with water, or open the pump for inspection
Packing is too tight Loosen the seasoning gland bolts, after starting the pump, slowly tighten the gland bolts until some water flows out
Scale or rust Soak in 10% oxalic acid for 30-60 minutes
Too much working fluid Adjust the working fluid to the axis of the pump
Winding short circuit Check motor winding

The working fluid volume is too large Adjust the working fluid inlet valve to reduce the working fluid flow
The exhaust pressure is too high Reduce the exhaust pressure to the specified range
Too much liquid in the inhaled gas Install a separator at the inlet, or reduce the amount of working fluid
Motor turns in wrong direction Replace both wires
No working fluid enters the pump Check the working fluid

Serious air leakage in the system Press down to check for leaks and repair
The intake valve is not open Open the intake valve
The working fluid flow rate is small Increase the working fluid flow rate and observe that the motor current cannot be overloaded
The temperature of the working fluid is too high Reduce the temperature of the working fluid
Slight leakage of the system Replace the seal (if the packing is sealed, tighten the gland bolts)
The vacuum gauge is not accurate Replace the vacuum gauge

Exhaust valve falls off Replace the exhaust valve
Pump selection is small Change to a larger pump
Impeller corrosion or cavitation Replace impeller
Severe cavitation Add cavitation protection device
The working fluid volume is too large Reduce the flow, method, install orifice plate or flow meter
The alignment of the coupling is not good. Recalibrate the concentricity of the coupling to make it meet the national standard or industry standard.

The footing bolts are not fixed properly Tighten the dead footing bolts
Impeller unbalanced Rebalance the impeller
