1. Product introduction
2XZ series rotary vane vacuum pump is a two-stage direct connection structure. Its working principle is composed of high pressure stage and low pressure stage. Its suction port is connected with the vacuum equipment. During operation, a large amount of gas in the container is sucked in and discharged. When the equipment gets vacuum, the high pressure exhaust valve is closed, and the gas sucked in by the high pressure stage will be transferred to the second stage, and then sucked in and discharged through the second stage. The vacuum equipment can obtain a certain degree of vacuum, The technical parameters of the modified pump are 6X10-2 pump and motor coupled, high speed, small shape, compact structure, and easy mobility. Our factory specially adopts metal scraper, which is suitable for the front pump of diffusion pump and the matching of precision instruments.
