In the industrial production process, the vacuum pump, as the core equipment of the vacuum system, its operating condition directly affects the production efficiency and product quality.

Many users encounter a problem during use: the pumping speed of the vacuum pump is getting slower and the vacuum degree fails to reach the required level for a long time.

So, what are the reasons for the decrease in the pumping speed of the vacuum pump?

I. Common Causes of Decreased Vacuum Pump Speed

1. Decreased Sealing Performance

After long-term operation, the sealing components of the vacuum pump may become aged, worn out, or damaged, allowing air to enter the system and thereby affecting the pumping efficiency.

Suggestion:

Regularly inspect the sealing rings and connection points.

Replace the sealing components promptly if any leakage is detected.

2. Decline in vacuum pump oil performance (applicable to oil-lubricated vacuum pumps)

For oil-lubricated equipment such as rotary vane vacuum pumps, the vacuum pump oil not only serves as a lubricant but also participates in sealing and cooling.

If the vacuum pump oil is not replaced for a long time, the following problems may occur:

Decreased vacuum degree

Reduced pumping speed

Increased equipment temperature

Suggestion:

Replace the dedicated vacuum pump oil regularly as per the equipment usage requirements.

3. Incompatible selection of vacuum pumps

Different processes have different requirements for vacuum degree, pumping speed and working environment. If the equipment selection is unreasonable, even if the vacuum pump is operating normally, it may still not be able to meet the production needs.

For example:

Food packaging

Composite material vacuum injection

Lithium battery manufacturing

Chemical process

Medical equipment

The requirements for vacuum systems in these industries vary greatly, so it is necessary to make scientific selections based on the actual working conditions.
