Dual level Rotary vane vacuum pump working principle

Dual level Rotary vane vacuum pump is a vacuum pump that uses rotating blades to compress gas. It consists of a rotor with two rotating blades and a stator. Here is how the Dual level Rotary vane vacuum pump works:

Preparation stage: When the Dual level Rotary vane vacuum pump is started, the rotor begins to rotate, and the gap between the rotating blades and the fixed blades is filled with oil seals to form a sealed state.

Low vacuum stage: When gas enters the pump chamber, as the volume of the pump chamber continues to decrease, the gas is compressed, forming a low vacuum.

High vacuum stage: When the gas is compressed to a certain extent, the gas enters the pump chamber of the second stage rotating blade and continues to be compressed to form a high vacuum.

Exhaust stage: When the gas is compressed to a certain extent, it is discharged from the pump chamber through the outlet, thereby forming a vacuum.

In short, the Dual level Rotary vane vacuum pump uses the compression of two-stage rotating blades to extract gas from a closed container or system to achieve the purpose of generating vacuum. Dual level Rotary vane vacuum pump has the advantages of high vacuum degree, high pumping speed, low noise, etc., and is widely used in vacuum processing and vacuum extraction in electronics, medical, chemical, food and other industries.

What factors affect vacuum degree

There are many factors that affect the vacuum degree of Dual level Rotary vane vacuum pump. Here are some of the main factors:

Gas type: Different types of gases have different effects on the degree of vacuum. Some gases that are easily adsorbed, such as water vapor, dissolved gases, etc., will affect the degree of vacuum.

● Pump leak rate: The lower the pump leak rate, the higher the vacuum.

● Pump sealing: The better the pump sealing, the higher the vacuum degree of the pump.

● Pump pumping rate: The higher the pump pumping rate, the faster the vacuum reaches the target value.

● Pump exhaust system: The diameter, length, and number of elbows of the exhaust pipe will all affect the vacuum degree.

● Pump usage environment: Environmental temperature, humidity and other factors will affect the vacuum degree of the pump.

● Load of the pump: The greater the load of the pump, the greater the impact on the vacuum degree of the pump.

Therefore, when using a Dual level Rotary vane vacuum pump, you need to pay attention to the above factors, minimize the air leakage rate, improve sealing, select the appropriate pumping rate and exhaust system, control the load, etc., to improve the vacuum degree of the pump . At the same time, regular maintenance and upkeep of the pump is also required, such as replacing lubricating oil, cleaning filters, checking seals, etc., to ensure the normal operation and long-term stability of the pump.
