2X rotary vane vacuum pump has two-stage structure, and its working performance consists of two parts: high-pressure stage and low-pressure stage. Its suction port is connected to a vacuum container or vacuum equipment, and a large amount of gas in the container will be sucked and discharged when working. When the equipment obtains vacuum, the exhaust valve of the high-pressure stage will be closed, and the gas inhaled by the high-pressure stage will be transferred to the second stage, and then sucked and discharged by the second stage, so that the vacuum equipment can obtain a certain degree of vacuum. The technical parameters of the pump are 6× 10-2pa. According to the user's usage, vacuum booster pump and 2X rotary vane vacuum pump can be configured as backing pumps. Due to the enhanced pumping force of the booster pump, the backing pump can continuously pump vacuum, which can make your equipment obtain higher vacuum.
Two. Application and scope of 2X rotary vane vacuum pump;
Due to the high development of modern science and technology, 2X rotary vane vacuum pump is widely used in various scientific fields and enterprises and institutions, mainly as follows:
1 can be used for scientific research, production and teaching in scientific research institutions, universities, industrial and mining enterprises, such as metallurgy, chemical industry, light industry, petroleum, medical treatment, pharmacy, printing and dyeing, electrical appliances, electric vacuum, semiconductors, food, atomic energy and textiles.
2. Because the 2X rotary vane vacuum pump is made of ferrous metal, it is relatively precise, and the whole pump works with oil, so it is not suitable for pumping all kinds of gases with high oxygen content, toxic and explosive corrosion to ferrous metal, and chemical effect on vacuum oil, nor can it be used as a compressor or delivery pump. If there is a pump with a gas ballast device, a certain amount of condensable gas can be pumped out.
3.2X rotary vane vacuum pump can directly obtain vacuum operation with vacuum degree below 10-3 torr, and cooperate with other vacuum equipment to obtain vacuum effect with vacuum degree above 10-3 torr.
4.2X rotary vane vacuum pump is generally used at room temperature not lower than 5℃ and relative temperature not higher than 90%.
According to the user's usage, it can be equipped with a vacuum booster pump as a backing pump. With the strengthening of the pumping force of the booster pump, the backing pump is continuously pumped out, and the equipment can obtain a higher vacuum degree. Introduction and application of X-type rotary vane vacuum pump:
X-type rotary vane vacuum pump is a single-stage rotary vane vacuum pump, which is the first new product to extract a large amount of water vapor in China. Because the pump itself has an oil regeneration device and a reliable gas ballast device, the service life of the pump oil is prolonged. X-type rotary vane vacuum pump is the basic equipment used to remove the gas in sealed container to obtain vacuum, which is suitable for electronic device manufacturing, vacuum drying, filtration, impregnation, coating, welding, smelting and laboratory equipment (special pump for handicrafts). It can be used independently, and can also be used as the backing pump of booster pump and diffusion pump, but it is not suitable for pumping from one container to another as a delivery pump. When pumping out gases with high oxygen content, explosiveness, corrosiveness to ferrous metals and chemical reaction to vacuum oil, such as water and ash, additional devices should be added. The main models are: X- 100 single-stage rotary vane vacuum pump and X- 150 single-stage rotary vane vacuum pump.
Second, the characteristics of X-type rotary vane vacuum pump:
1 Compared with XD series single-stage vacuum pumps, it has higher limit vacuum. For slide valve vacuum pump, noise can be controlled by adjusting the silencing needle valve. Because the eccentric mass of the rotor is small and the rotor is balanced, the vibration is small.
2.x series rotary vane vacuum pump has high pumping efficiency.
3.x series rotary vane vacuum pump has good gas ballast performance.
X series rotary vane vacuum pump has a specially designed gas ballast device, which can fill dry gas into the exhaust cavity, thus greatly reducing the partial pressure of steam in the exhaust. When it is lower than the saturated vapor pressure at the pump temperature, it can be discharged from the pump together with the pressurized air to avoid condensation in the pump.
4.X series rotary vane vacuum pump is equipped with temperature-controlled water quantity regulating valve.
When the pump is working, the pump temperature can be adjusted to 75oC±5oC by adjusting the water pressure provided by the pump itself, so as to improve the pump displacement, but the pump temperature should not exceed 80oC (the temperature measuring point of the oil tank).
5.x series rotary vane vacuum pump has oil-water separator.
It can make the impurities and condensate in the pump oil accumulate at the bottom of the oil-water separator and be discharged from the pump through the drain valve installed at the bottom. I. Overview of 2XZ rotary vane vacuum pump:
