The vacuum pump 275 factory believes that the vacuum pump is a large-scale and wide-ranging product with a large output and a low output value, but it is indeed an essential basic product that directly affects the performance and quality of the vacuum complete set of equipment. The vacuum pump 275 factory believes that the market of vacuum pumps changes dynamically according to the needs of users.

　　There are many 275 factories producing vacuum pumps in my country, and the annual sales of all vacuum pumps are about 150 million yuan. Through the analysis of the global vacuum pump market, we can see that the market and application fields of various vacuum pumps are constantly changing and developing. At present, the annual sales of the global vacuum pump market is about 2 billion US dollars, and the annual growth rate is about 7%.

　　Vacuum Pump Features

　　(1) The vacuum pump 275 factory believes that it has a larger pumping speed in a wider pressure range; (2) The rotor has good geometric symmetry, so the vibration is small and the operation is stable. (3) The factory of vacuum pump 275 feels that there is no need to seal and lubricate the pump chamber with oil, which can reduce the pollution of oil vapor to the vacuum system; (4) There is no compression and no exhaust valve in the pump chamber. (5) The vacuum pump factory 275 felt that the compression was relatively low, and the effect of hydrogen pumping was poor; (6) The surface of the rotor was a curved cylinder with a complex shape, which was difficult to process and inspect.
