2XZ-B series rotary vane vacuum pump is a two-stage direct-coupled rotary vane vacuum pump. Its working performance consists of two parts: high pressure stage and low pressure stage. Its suction port is connected with vacuum equipment, and the gas in the container is operated during operation. A large amount of inhalation and discharge, when the equipment is vacuumed, the high-pressure exhaust is closed, the gas inhaled by the high-pressure stage will be transferred to the second stage, and discharged through the second stage to discharge, and the vacuum equipment can obtain a certain degree of vacuum, 2XZ -B series rotary vane vacuum pump technical parameters are 6×10-2, pump and motor shaft, high speed, small size, compact structure, convenient fluidity, our factory special metal scraper, suitable for diffusion pump The foreline pump, precision matching, laboratory, medicine, food packaging, electronic, electric light source and other units.

2XZ-B series rotary vane vacuum pump features: small size, light weight, low noise, easy to start and so on. 2XZ-B series rotary vane vacuum pump is equipped with gas ballast valve, which has the function of prolonging pump oil use time and preventing pump oil from mixing. In addition, it also has measures to prevent oil return (2XZ-8) and prevent oil seal oil pollution. Site measures. Made of ferrous metal and aluminum alloy, it is a more sophisticated equipment. The main working parts of the 2XZ-B series rotary vane vacuum pump are immersed in a special vacuum pump oil. Therefore, it is not suitable for the removal of oxygen-containing, toxic, explosive. Gases that react chemically to vacuum pump oil or corrode ferrous metals, and are not used as compressors and transfer pumps.

1. Prepare a specially designed gas ballast valve to prevent pump oil from mixing and prolong the use time of pump oil;
2. High pumping efficiency, high ultimate vacuum and long service life;
3, with automatic anti-return oil check valve, never return oil;
4, small diameter 2XZ-4B vacuum pump is equipped with vacuum drying oven, freeze dryer, printing machinery;
5, can be equipped with small diameter adapter, KF interface, flange interface;
6. When the suction contains steam, particles, corrosive gas, auxiliary equipment such as condenser and dust collector shall be installed at the inlet of the pump.
