2X Rotary Vane Vacuum Pump

2X Rotary Vane Vacuum Pump--Product overview

The 2X rotary vane vacuum pump has a two-stage structure. Its working performance is composed of two parts: a high-pressure stage and a low-pressure stage. Its suction port is connected to a vacuum container or vacuum equipment, and a large amount of gas in the container is sucked and discharged during operation. When the equipment obtains vacuum, the high-pressure stage exhaust valve plate will be closed, and the gas sucked by the high-pressure stage will be transferred to the second stage, and then sucked and discharged through the second stage, so that the vacuum equipment can obtain a certain vacuum. The technical parameters of the pump are 6×10-2pa. According to the user's usage, it can be equipped with a vacuum booster pump (such as a Roots vacuum pump). The 2X rotary vane vacuum pump is used as the backing pump. Due to the enhanced suction power of the booster pump, the backing pump can be continuously pumped out, which can make your The equipment obtains a higher vacuum.

The 2X type rotary vane vacuum pump is the basic equipment used to extract gas from a sealed container to obtain a vacuum. Its working principle is the same as that of a general variable-capacity vacuum pump. It consists of a rotor that is installed concentrically with the drive shaft and is eccentric in the pump body. There are two sliding blades on the rotor, which are also called rotary vanes. When the rotor rotates, the two blades are acted by centrifugal force on the one hand, and spring force on the other hand, so that it can keep tightly in contact with the inner wall of the pump body, dividing the pump body into two working rooms. The volume on one side keeps expanding, the gas keeps expanding and sucking in the gas, while the other side keeps shrinking, and the gas keeps compressing and expelling the gas to achieve the purpose of pumping. This operation is repeated twice per revolution.

2X Rotary Vane Vacuum Pump--Product features

The 2X rotary vane vacuum pump is the basic equipment used to extract the gas from the sealed container to obtain the vacuum. It is also the most widely used vacuum pump in China. It has two types of water cooling and air cooling. Compared with similar domestic products, this pump has a high vacuum. , Small size, light weight, fast pumping speed, easy to use, simple to install and maintain, and the following advantages:

1. There is a gas ballast valve in the pump to remove a small amount of water vapor;
2. The ultimate vacuum of the rotary vane vacuum pump is high;
3. The built-in compulsory oil inlet, sufficient lubrication and reliable performance;
4. Equipped with automatic anti-return oil double safety device;
5. It can still run continuously when the intake pressure is 1.33×10Pa;
6. No oil leakage, no fuel injection, and no pollution to the working environment.
