Oil free vacuum pump plays a very obvious role in many fields, such as refrigeration and maintenance of air conditioners, suction devices of medical instruments, vacuum packaging, physical and chemical experiments and other vacuum functions. It plays a good role. So how does oil-free vacuum pump mainly realize these functions? Is this related to its structure? How does the structure diagram and structural characteristics of oil-free vacuum pump show?
Structure diagram and structural characteristics of oil-free vacuum pump
Wx vacuum pump is an oil-free vacuum pump, which is one of the equipment to obtain vacuum. The limit vacuum of Wx vacuum pump is 6 × 10-2MPa。 The pump is eccentrically placed in the pump body by the rotor. The rotation of the rotor and the rotating blade constantly changes the volume of the pump on both sides of the body: the volume of one side is expanded to absorb gas, and the volume of the other side is reduced to discharge gas. Thus, the suction and discharge of gas are completed periodically, so as to obtain vacuum. The structures of pumps with different specifications are slightly different. If the exhaust pipe of wx-4 and 8 is at the bottom of the pump, please pay attention to it.

Through the above introduction of Wx oil-free vacuum pump, it can be found that due to different models, the structure diagram of Wx oil-free vacuum pump is also different, so its use environment and realizable function may be different. Because of the market demand, the development speed of oil-free vacuum pump is very fast in recent years, and there are also many good products. In the future, the market of oil-free vacuum pump will be broader. We need to further study the structure diagram of oil-free vacuum pump and comprehensively improve its structural characteristics, which is not only for the future of oil-free vacuum pump, but also for the sake of China's economy.
Oil free vacuum pump is composed of stator, rotor, rotor, cylinder block, motor and other main parts. The rotor with rotating blades is eccentrically installed in the stator cylinder. When the rotor rotates at a high speed, the four radial sliding rotating blades in the rotor slot divide the pump cavity into four working chambers. Due to the centrifugal force, the rotating blades cling to the cylinder wall, separating the stator inlet and outlet, and running round and round, changing the volume, and discharging the inhaled gas from the exhaust port, so as to achieve the purpose of air extraction.
