Molecular fluid vacuum pump vacuum principle is the use of the principle of momentum transfer, the molecules do directional flow and the gas is discharged from the pump, in order to achieve the purpose of pumping. Understanding the working principle of molecular vacuum pump for the most efficient use of this product is of extraordinary significance, then the main part of the molecular vacuum pump is how to work. Molecular vacuum pump working principle and structure Molecular vacuum pump driven by the motor to do high-speed rotation, the use of variable frequency power drive motor, so the purpose is to hope to achieve higher speed. In the area of ​​molecular flow, the gas molecules collide with the surface of the blade which is transferred to the high speed, and the momentum is transferred to the gas molecules so that part of the gas molecules are directed to flow out of the pump in the direction of the movement of the rigid body surface to achieve the purpose of gas extraction . Usually with high-speed motion of rigid body surface to carry gas molecules, and make it move in a certain direction known as molecular traction phenomenon, the use of this phenomenon made of vacuum pump called traction molecular vacuum pump. Traction molecular vacuum pump has the advantage of short start-up time, in the molecular flow state has a high compression ratio, can remove all kinds of gases and vapors, especially for pumping heavier gases. However, due to traction molecular vacuum pumping speed is small, the sealing gap is too small, poor reliability, easy to fall out of machinery, and manufacturing difficulties, in fact rarely used. Later on the traction molecule vacuum pump was improved, there has been a turbo molecular vacuum pump. Turbomolecular vacuum pump within the group of multi-phase moving wheel and fixed wheel leaves, each wheel has a number of inclined at a certain angle blades. The actual turbo molecular vacuum pump is composed of multi-stage leaf cascade, that is, pressing the film, fixed film, moving films, etc. are alternately arranged. When moving the blade is similar to the role of electric fan blades, the gas can be drawn from one side to the other side. Improve molecular vacuum pump speed, help to improve the molecular vacuum pumping speed. Due to the limitation of the speed of the blades, it is more difficult to pump the vacuum if the gas molecules move faster. Turbomolecular vacuum pump ultimate vacuum diffusion pump to be higher, up to 10-8pa. However, its normal work requires a certain level of vacuum, depending on the level of vacuum slightly different pump. As China's economy continues to evolve, it faces a huge market for the vacuum pump industry, but it also faces enormous challenges and how these products can be adapted to our economic development. For all types of products, we understand Its working principle is the most basic work. Related staff can further study the related issues.
