Rotor vane vacuum pump wear cause and repair method

Just as books wrinkle when they are read for a long time, sweaters pilling when they are worn for a long time, and shoes break when they are worn for a long time.Mechanical products are no exception,any mechanical product will wear out when it has been working for a long time.Let’s discuss with Lanphan about the reasons for the wear of the rotary vane vacuum pump and how to reduce the wear and increase the vacuum, thus enhancing the work efficiency.The rotary vane vacuum pump uses vacuum oil as the sealing medium, and the oil acts in addition to sealing and lubrication.Oil deterioration leads to performance degradation, it is easy to aggravate the vacuum pump wear.Vacuum pump is to obtain vacuum equipment, if a long time can not get vacuum, the load of the pump is large, also easy to produce wear.

For the problem of the difference between the rated head and the actual running head of the rotary vane vacuum pump, we can reduce the outer diameter of the working wheel by cutting, and reduce the head and flow to make it consistent with the actual lift.Changing the design work point of the rotary vane vacuum pump is an effective way to improve the operating efficiency of the rotary vane vacuum pump.

Although the rotary vane vacuum pump is easy to corrosion, it is still popular because of its high vacuum.Anyone who knows about the vacuum pump will know that the vacuum of the rotary vane vacuum pump is high because the gap between the rotary vane and the rotor is very precise.Therefore, once the rotor is worn, it will definitely have a great impact on the performance of the rotary vane vacuum pump. Next, I will analyze the reason and repair method of rotary vane vacuum pump wear for you. Next, I will analyze the cause and repair method of the rotary vane vacuum pump for you.Next, I will analyze the cause and repair method of the rotary vane vacuum pump for you.

Firstly,What are the causes of wear and tear?  1.The vacuum pump enters dirty objects or hard solid particles, and collides with the rotating piece for a long time, causing damage to the rotating piece.  2.The normal wear of the rotary vane is also an important reason, and the wear of the rotary vane will increase when the vacuum pump oil is emulsified.  3. The rotary vane vacuum pump has better performance, uniform pumping, low noise and low power consumption.

4.After prolonged use, the sealing performance will be degraded due to the wear of the rotary vane, which will greatly reduce the pumping volume and vacuum.

Secondly:How to repair worn rotary vane and increase vacuum?

1.In the case of large wear and tear, the rotary vane can be replaced with new ones if the processing capacity permits. Because it is more convenient to change the new rotary vane than the end of the grinding pump cavity.

2.If the rotary vane is worn out, the rotary vane is first corrected with the smallest dimension of the rotor. The fine crepe paper can be pushed flat, and the size and the square rule are measured while grinding until no clear gap is visible.

3.If the rotor is worn much, it is first applied to the grinding machine. Then, according to the selected gap value, the rotor and the pump chamber are scraped and ground to ensure the matching gap between the three.

Finally, I want to introduce a 2XZ series rotary vane vacuum pump produced by our company for your reference.

Rotary vane series vacuum pump is a two-stage high-speed direct-coupled rotary vane vacuum pump, which is one of the basic equipment for removing gas from a sealed container.A rotor is arranged in the pump chamber, and a rotary vane is arranged in the rotor slot. When the rotor drives the rotary vane to rotate, the rotary vane is closely attached to the chamber wall, the inlet and exhaust ports are separated, and the volume of the intake manifold is periodically expanded. Inhalation, the volume of the exhaust chamber is periodically reduced to compress the gas, and the exhaust valve is exhausted to obtain a vacuum.Its working performance consists of two parts: high pressure stage and low pressure stage. Its suction port is connected with vacuum equipment. When operating, the gas in the container is inhaled and discharged in large quantities. When the equipment is vacuumed, the high pressure stage exhaust valve is closed and the high pressure is closed. The gas at the stage inlet will be transferred to the second stage, and a certain vacuum can be obtained by inhaling and discharging the vacuum device through the second stage.The pump and motor of 2XZ series rotary vane vacuum pump are connected with shaft, high speed, small size, compact structure and convenient fluidity.

The above is the cause and repair method of the rotary vane vacuum pump. If you want to know more about the vacuum pump, please contact Henan Lanphan Industrial Co., Ltd.
