Molecular vacuum pump type and model Daquan

Molecular fluid pump is the use of high-speed rotating rotor to transfer momentum to the gas molecules, so that the directional speed, which is compressed, was driven to the exhaust port after a vacuum pump. Molecular vacuum pump suction principle and volumetric mechanical pump pump chamber volume changes based on the principle of different pumping, so there is a big difference between the types, but in general molecular vacuum pump was born, the mechanical vacuum pump in the pumping principle A new breakthrough. Molecular vacuum pump Next, we will mainly introduce the three members of the molecular vacuum pump: 1, molecular drag traction molecular gas molecules and high-speed motion of the rotor to obtain momentum, was driven to the pump outlet. The rotor of the traction molecular pump has a rotatable rotor. The rotor is surrounded by grooves and separated by baffles. Each groove is equivalent to a single-stage molecular pump, the inlet of the next stage is connected to the outlet of the previous stage. 2, Turbomolecular pump by high-speed rotation of the moving blades and stationary blades cooperate to achieve pumping. Such pumps usually work in molecular flow conditions. Turbo molecular pump has the advantages of fast start-up, resistance to various radiation exposure, resistance to atmospheric impact, no gas storage and desorption, no oil vapor pollution or little pollution, to obtain a clean ultra-high vacuum. 3, composite molecular pump It is a combination of turbo-and two-molecular pump traction in combination of a composite molecular vacuum pump. The pump eliminates the need for cold traps and oil baffles for a clean, high vacuum and ultra-high vacuum environment. Compared with the general vacuum pump, molecular vacuum pump has a start-up time is short, in the molecular flow state has a high compression ratio, can be extracted from a variety of gases and vapors, especially suitable for pumping heavier gas advantages. However, due to its structure is still more complex, pumping speed and other disadvantages, it has not been widely used. However, with the increasing demand for vacuum pumps in our country and the continuous updating of relevant technologies, it is believed that molecular vacuum pumps will have their own glory in the near future.

Phosphate rock powder is a natural, untreated. Phosphate rock powder is a natural, untreated phosphate. When applied to the soil, phosphate rock will become part of the soil. Once applied, the phosphate rock does not leach and it remains in the soil until it is absorbed by the plant. Phosphate contains no harmful acids, it also encourages the growth of bacteria and earthworms in the soil. Phosphate rock powder can be used as a base fertilizer once, and the fertilizer effect can be maintained for several years. At the same time, it is a kind of phosphate fertilizer. This organic fertilizer contains 28% to 32% P2O5.
