2X rotary vane vacuum pump

The rotary vane vacuum pump is a two-stage eccentric vane structure. It has an eccentric device, the rotor in the pump hole and the rotating blade in the rotor slot. When the rotor drives the rotary vane to rotate, the rotating vane is tightly adhered to the cavity wall, which separates the air inlet and outlet, and periodically expands the volume of the air inlet chamber to inhale, while the volume of the exhaust chamber periodically shrinks the gas and pushes the exhaust to obtain vacuum.

The rotary vane vacuum pump is a two-stage eccentric vane structure. It has an eccentric device, the rotor in the pump hole and the rotating blade in the rotor slot. When the rotor drives the rotary vane to rotate, the rotating vane is tightly adhered to the cavity wall, which separates the air inlet and outlet, and periodically expands the volume of the air inlet chamber to inhale, while the volume of the exhaust chamber periodically shrinks the gas and pushes the exhaust to obtain vacuum. Compared with the domestic similar products, 2x rotary vane vacuum pump has the advantages of less power consumption, high vacuum degree, low noise, beautiful appearance and light weight. The shape and structure of all kinds of 2x rotary vane vacuum pump are basically the same. The pump is driven to the rotor by the motor through the triangle belt. The motor and pump are fixed on the chassis with screw clamp plate.

Type 2x rotary vane vacuum pump is composed of pump body, high rotor, low rotor, front end plate, rear end plate, high rotor, low rotor, exhaust valve, exhaust hood, mirror and other parts.

A middle diaphragm is pressed into the pump body of 2x rotary vane vacuum pump, and the pump shell is divided into high and low vacuum chambers. Each chamber has an exhaust valve. The exhaust of high vacuum chamber is connected with the intake of low vacuum chamber. The front end of the high rotor extends out of the front axle and the rear end extends out of the rear axle. The front axle is supported by the bearing of the front end plate and extends out of the front plate through the oil seal chamber; the rear axle is supported by the bearing on the middle partition plate. The rotor of the low vacuum chamber is installed on the rear axle, so the high and low rotors are driven by the front axle. Both high and low rotors have split slots, and the T-shaped blades are installed in the slots by springs. There is a filter screen at the air inlet and an oil screen at the exhaust port of the 2x rotary vane vacuum pump.

Application fields of 2x rotary vane vacuum pump:

1. Type 2x rotary vane vacuum pump is a basic equipment used to remove the gas in a specific sealed container, so that the container can obtain a certain vacuum. Due to the high development of modern science and technology, vacuum pump is widely used in various scientific fields and enterprises and institutions. It can be used in metallurgy, chemical industry, light industry, petroleum, medical treatment, pharmacy, printing and dyeing, electrical appliances, electric vacuum, semiconductor, food, etc Atomic energy, textile and other scientific research institutions, colleges and universities, industrial and mining enterprises are used for scientific research, production and teaching.

2. Because the 2x rotary vane vacuum pump is made of ferrous metal, and is more precise, the work of the whole pump is linked together. Therefore, the 2x rotary vane vacuum pump is not suitable for pumping all kinds of gases that contain too much oxygen, toxic, explosive, etching ferrous metal and chemical action on vacuum oil, and can not be used as compressor and delivery pump. If there is a pump with gas ballast device, a certain amount of condensable steam can be removed.

3. Type 2x rotary vane vacuum pump can be used to directly obtain vacuum operation with vacuum degree below 10 ~ 3 Torr, and cooperate with other vacuum operation.

4. Type 2x rotary vane vacuum pump is generally used in the room temperature not lower than 5 ℃ and the relative temperature not higher than 90%.
