1、 Overview of 2X rotary vane vacuum pump

The 2X rotary vane vacuum pump is a two-stage rotary vane oil sealed rotary mechanical vacuum pump, which is one of the main equipment for low and medium vacuum. It can be used alone or as a front-end pump for high vacuum pumps such as Roots vacuum pump, diffusion vacuum pump, worm gear molecular vacuum pump, etc. It is the basic equipment used to extract gas from sealed containers and obtain vacuum. Its working principle is the same as that of a general vacuum pump. It is composed of a rotor installed in the same core as the transmission shaft and in an eccentric position inside the pump body. There are two radial sliding blades on the rotor.

Due to the highly developed modern science and technology, 2X rotary vane vacuum pumps are widely used in various scientific fields and various enterprises and institutions. They can be used for scientific research, production, and teaching in research institutions such as metallurgy, chemical industry, light industry, atomic energy, electric vacuum, petroleum, printing and dyeing, semiconductor, food, electrical appliances, textiles, and other industries.

2、 Application range of 2X rotary vane vacuum pump

The 2X rotary vane vacuum pump is suitable for low and medium vacuum fields. It is a basic equipment used for sealing containers to extract gas and obtain vacuum. Mainly used for extracting air and other dry gases. But it cannot suck gases that are corrosive, flammable, or explosive, nor can it suck gases containing small particles or dust, and it cannot transport other small objects.

The 2X rotary vane vacuum pump is capable of long-term operation in well ventilated indoor environments with an ambient temperature of 5-40 ° C and humidity of ≤ 90%.

In addition to the above application scope, the 2X rotary vane vacuum pump can also expand its application range. For example:

1. To increase the pumping volume and improve the vacuum degree, it can be combined with a Roots pump to form a Roots rotary vane vacuum unit.

2. If extracting humid air or condensable gases, a condenser can be installed in front of the vacuum pump, and a gas damper can be installed on the vacuum pump.

3. If extracting gas with dust particles, a dust filter can be installed before the vacuum pump.

4. If extracting corrosive gases, an anti-corrosion gas filter can be installed before the vacuum pump.

3、 Working principle of 2X rotary vane vacuum pump

This vacuum pump operates according to the rotary vane principle.

The rotor rotates around the axis of the 2X rotary vane vacuum pump, and the driving motor drives the vacuum pump shaft through a belt and pulley. The rotor rotates inside the circular pump body, and the centerline of the pump body deviates from the rotor axis. Therefore, the rotor forms a linear contact with the inner wall of the pump body. The blades slide along the sliding groove of the rotor, separating the pump body and rotor into two working chambers. When the working chamber is connected to the inlet, gas is sucked in. With the rotation of the rotor, the sucked in gas is compressed and discharged into the oil. A constant pressure difference causes vacuum lubricating oil to enter the compression chamber. Lubricating oil and the extracted gas enter the oil together, and through gravity and oil gas separation, the lubricating oil falls back into the oil tank and enters the oil circulation. The oil-free gas is discharged to the atmosphere through the exhaust port, thus achieving the purpose of extraction. This operation is repeated twice per revolution.

To avoid inhaling solid particles, the vacuum pump is equipped with a suction filter screen.

To avoid reverse rotation of the blades after turning off the power, the exhaust valve of the vacuum pump has a reverse closing effect.

If the 2X rotary vane vacuum pump is equipped with an air damper (optional), a small amount of air enters the vacuum pump chamber through the air damper and is compressed together with the process gas, which can prevent the condensation of condensable gas components in the process gas inside the vacuum pump chamber.

The gas control valve has a throttle valve function and can be partially or completely closed.

In order to improve the working characteristics of the vacuum pump, an exhaust valve is installed at the exhaust port of the pump body.
