How to deal with the vacuum pump not pumping vacuum?

How to deal with the vacuum pump not pumping vacuum? A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physical-chemical methods to evacuate the pumped container to obtain a vacuum
.

In layman's terms, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a closed space
.

So, what to do when the vacuum pump doesn't pump vacuum? Let’s find out with me below
.

Reasons and solutions for the vacuum pump not pumping vacuum: 1.
Whether the power cord of the vacuum pump is reversely connected or lacks phase, the motor is not turning right, and it needs to be repaired
.

2.
The pipeline between the container and the vacuum pump is blocked or leaked, whether the air filter element is blocked, and the garbage needs to be cleaned for a long time
.

3.
The vacuum pump blade is broken and will not generate a vacuum, and the blade needs to be replaced
.

4.
Check the vacuum pump oil, the vacuum pump oil should be injected in an appropriate amount, and it should be replaced after a long time of use
.

Other oils are strictly prohibited
.

 　　5.
The sealing degree of the pumped system does not meet the requirements, and the leakage of the container is too large
.

Check exclusions
.

 　　6.
The pump oil is polluted and needs to be changed
.

 　　7.
The oil filter in the pump is blocked, causing the oil circuit of the compression oil injection system to be blocked, and the oil supply is insufficient, resulting in the poor sealing of the pump body.
At this time, the internal oil filter needs to be cleaned; the valve of the oil distributor is deformed, worn or damaged.
If the oil supply is insufficient, the valve of the oil distributor should be checked and replaced; long-term use will cause the wear of the rotary vane of the vacuum pump or the insufficient spring tension in the rotor, resulting in the poor isolation of the suction chamber and the exhaust chamber, thus causing the vacuum pump to be evacuated Performance drops
.

At this time, the rotary vane and spring should be replaced, and the rotor and pump cavity should be cleaned; check the exhaust valve to see if its action fails, resulting in poor exhaust, and replace the exhaust valve
.

 　　The above is the introduction of the vacuum pump non-vacuum treatment method.
I believe that everyone has a corresponding understanding of this after reading it.
You can use it as a reference and hope to help you
