Analysis of rotary vane vacuum pump technology and discussion on application of LeyNow vacuum pump

Rotary vane vacuum pump , as an important equipment in the field of vacuum technology, plays a key role in many fields such as industrial production and scientific research experiments with its unique structure and working principle. This article will delve into the structure and schematic diagram of the rotary vane pump , the working principles of single-stage and two-stage rotary vane vacuum pumps , as well as the vacuum degree and parameter characteristics that the rotary vane pump can achieve, and on this basis, introduce the relevant aspects of LeyNow vacuum pumps application.

1. Structure and schematic diagram of rotary vane vacuum pump

Rotary vane vacuum pumps are mainly composed of pump body, rotary vane, rotor, intake and exhaust ports and other components. It has a compact structure and its working principle is based on volume changes. Inside the pump body, the rotor drives the rotary vanes to rotate, and the rotary vanes slide close to the inner wall of the pump body under the action of centrifugal force, thereby dividing the pump body into multiple working chambers. As the rotor rotates, the volume of the working chamber continuously changes, realizing the suction, compression and discharge of gas.

The schematic diagram intuitively shows the working process of the rotary vane pump. In the suction stage, the volume of the working chamber increases and the gas is sucked in through the air inlet; in the compression stage, the volume of the working chamber decreases and the gas is compressed; in the exhaust stage, the compressed gas is discharged out of the pump through the exhaust port. During the whole process, the continuous sliding of the rotary vane ensures the continuous suction and discharge of gas.

2. Working principle of single-stage rotary vane vacuum pump

The working principle of a single-stage rotary vane vacuum pump is relatively simple. Driven by the motor, the rotor drives the rotary vane to rotate at high speed in the pump body. Due to the centrifugal force, the rotary vane is close to the wall of the pump body, dividing the pump body into several working chambers. As the rotor rotates, the volume of the working chamber changes periodically, thereby realizing the suction, compression and discharge of gas. Single-stage rotary vane vacuum pumps are usually used to pump gases with low vacuum levels.

3. Working principle of two-stage rotary vane vacuum pump

The two-stage rotary vane vacuum pump is more complex in structure than the single-stage pump, but its vacuum extraction capacity has been significantly improved. A two-stage pump usually consists of two single-stage pumps connected in series. The front-stage pump is responsible for pumping gas from atmospheric pressure to a lower vacuum, while the back-stage pump further pumps gas to a higher vacuum based on the front-stage pump. This structure enables the two-stage rotary vane vacuum pump to have better performance when pumping high vacuum gas.

4. How much vacuum can the rotary vane pump pump?

The vacuum extraction capabilities of a rotary vane pump depend on its design and manufacturing process. Generally speaking, single-stage rotary vane vacuum pumps can extract lower vacuum levels, while two-stage rotary vane vacuum pumps can achieve higher vacuum levels. However, it should be noted that the vacuum pumping capacity of a rotary vane pump is also affected by many factors such as the working environment, gas type and pump status. Therefore, when selecting a rotary vane pump, comprehensive considerations need to be made based on actual needs and conditions.

5. Rotary vane vacuum pump parameters

The parameters of the rotary vane vacuum pump include pumping rate, ultimate vacuum degree, power, noise, etc. The pumping rate refers to the volume of gas that the pump can pump per unit time and is one of the important indicators for measuring pump performance. The ultimate vacuum degree indicates the lowest vacuum degree that the pump can achieve when operating stably, reflecting the pump's pumping capacity. Power and noise are parameters related to the efficiency and comfort of the pump. When selecting a rotary vane vacuum pump, these parameters need to be comprehensively considered based on specific application scenarios and needs.
