2 rotary vane vacuum pump

Overview of the vacuum pump of two-rotor blades:
Type 2 rotary vane vacuum pump is a two-stage structure. Its performance is composed of two parts: high pressure and low pressure. Its suction inlet is connected to a vacuum vessel or vacuum device, and the gas in the container is inhaled in large quantities during operation. When the equipment is vacuumed, the high-pressure stage exhaust valve will be closed, and the gas inhaled by the high-pressure stage will be transferred to the second stage and the inhalation and discharge through the second phase will enable the vacuum equipment to obtain a certain vacuum. The technical parameters of the pump are 6 x 10-2pa. According to the user's use, it can be equipped with a vacuum booster pump (such as the roots vacuum pump), and the 2X rotary vane vacuum pump as the front pump. Due to the enhanced pumping capacity of the booster pump, the former pump can be pumped continuously to obtain higher vacuum degree for your equipment.

The purpose and scope of application of the rotary vane vacuum pump:
With the development of modern science and technology, the application of 2 rotary vane vacuum pump has been widely used in various scientific fields and various enterprises and institutions. Its main properties are:
1. For metallurgy, chemical, light, oil, medicine, pharmaceutical, printing, printing, electronic, vacuum, semiconductor, food, nuclear, nuclear, industrial, industrial, industrial, industrial, industrial, industrial, industrial, industrial, industrial, industrial, industrial, industrial, industrial, industrial, industrial, and teaching.
2. Because the two rotary vane vacuum pump is made of black metal, relatively accurate, the pump work related to oil, therefore not suitable for extraction of oxygen, toxic, explosive gas, the gas attack of black metal, cannot be used in the compressor and the function of vacuum oil transfer pump. If there is a gas ballast pump, a certain amount of condensing steam can be removed.
3. The 2X rotary vane vacuum pump can be used to directly obtain the vacuum degree less than 10-3 Torr vacuum operation, and the vacuum degree of vacuum equipment, such as the Torr vacuum effect, is more than 10-3.
4. Type 2 rotary vane vacuum pumps are commonly used are not at room temperature of 5 ℃ and relative humidity is no more than 90% ℃ environment.
Vacuum booster pump can be configured according to user requirements. The pump is used as a front pump to form rotss rotary vane vacuum unit. As the pumping capacity of the booster pump, its front pump can pump continuously to make your equipment. Get a higher vacuum.
The significance of the model of the third and second rotary vane vacuum pump:
