Description

technical field [0001] The invention relates to a vacuum pump, in particular to a direct-drive high-speed turbo vacuum pump and an operating method thereof. Background technique [0002] As the vacuum application technology has more and more requirements for its pumping capacity and vacuum range in the field of production and scientific research, most of them need to be composed of vacuum pumps and other equipment to form a vacuum pumping system to meet the production and scientific research process. Therefore, there are many situations where a vacuum pumping system composed of different types of vacuum pumps is used for pumping air. Currently, positive displacement vacuum pumps such as rotary vane vacuum pumps, Roots vacuum pumps and water ring vacuum pumps are used, which are mainly used in electric power, Chemical industry, light industry, mining, medicine, electronics, aerospace, scientific research and other departments. [0003] Water ring vacuum pump is a relatively ...

Problems solved by technology

[0003] Water ring vacuum pump is a relatively common variable capacity low-pressure vacuum pump. The rotor with multi-blade impeller is eccentrically installed in the pump body. When rotating, water is used as the working fluid, and suction, compression and exhaust are realized by the change of the volume of the pump chamber. Gas, so it needs to consume water and the energy consumption acting on water. Its efficiency is currently about 50%, and its speed is generally lower than 3000r / min. The control range is very limited. After a certain point, the water ring will collapse

[0004] In addition, ZL200710071245.3 "cantilever high-speed turbo vacuum pump and its vacuum pumping method", ZL200810219408.2 "a multi-stage turbo vacuum machine and its application Flat vacuum pump and its vacuum pumping method”, the above-mentioned turbo vacuum pumps all drive the speed increase box to achieve high speed through the motor and coupling. , The mechanical transmission efficiency loss of the bearing is about 10% and the energy consumption at the cooling fan, the maintenance is complicated, the floor area is large, and the mechanical failure points at the gearbox and the coupling are increased, and it is difficult to achieve a variable suction process with a fixed speed transmission Necessary and other disadvantages; for multi-stage turbo vacuum pumps, once a failure occurs, the entire production line will be stopped, seriously affecting normal production and causing great economic losses, and the maintenance period is long

[0005] According to the lack of high power consumption or water consumption of positive displacement vacuum pumps, and at the same time aiming at the shortcomings of ordinary fixed-speed high-speed turbo vacuum pumps, such as large speed-up transmission loss and many hidden dangers of failure points, combined with high-efficiency, high-speed, compact, and large pumping capacity of turbo vacuum pumps and other advantages, while meeting the requirements of different pumping volumes and vacuum degrees, it can maximize production efficiency and minimize production losses caused by failures. Further consider a new direct-drive single-stage or double-stage high-speed The flat vacuum pump is very valuable in application and practical significance, in order to adapt to the development needs of modern industry in terms of the maximum efficiency and environmental protection of vacuum pumping and compression equipment; this is the starting point of the present invention
