Multi Stage Claw Type Dry Vacuum Pump

Claw Vacuum Pumps Claw vacuum pumps, like Roots vacuum pumps and screw vacuum pumps, are non-contact dry vacuum pumps. Generally, in order to achieve a certain compression ratio, rotational speed and dynamic balance, claw vacuum pumps are composed of multi-stage claw rotors in series or Roots rotors in series with multi-stage claw rotors. At present, most of the common types are three-stage claw rotor plus one-stage Roots rotor, or four-stage claw rotor in series. The performance of the Roots-claw type is generally better than that of the full-claw type claw vacuum pump. Claw vacuum pump Characteristic 1) The rotor adopts the spiral anti claw structure, and has a number of scientific and technological invention patents 2) The rotor is made of 17-4PH special stainless steel, which is precision cast and has strong corrosion resistance. 3) The compound seal technology with invention patent is more reliable and has longer service life than mechanical seal. 4) Adopt step by step compression energy saving design, reduce energy consumption by 30% 5) Vertical structure, more smooth drainage, strong ability to pump condensable gas and gas-liquid mixture 6) Vertical structure is adopted, which is easier to clean for the working condition with dust 7) Modular structure design, simple and convenient maintenance, most of the maintenance work can be completed on site, no need to return to the factory. 8) High safety, no contact wear in internal design, no pollution of materials 9) Green environmental protection, no pollution, no pollution, no waste disposal cost.. 10) The surface of the working chamber is provided with anti-corrosion coating, which can adapt to severe working conditions. Generally speaking, the claw vacuum pump has the following main characteristics: (1) There is no lubricant in the pump chamber and no oil return. (2) Clean exhaust, no pollution to the pumped containers and gases, and the pumped gases can be recycled to reduce consumption and emission reduction; (3) The airflow in the pump chamber moves vertically, and a small amount of particulate matter is easily removed under the action of gravity. (4) The non-contact pumping element can realize high-speed operation. (5) The rotor pair is suspended in the pump chamber, and there is no contact between the rotor pair and the pump chamber. It has no friction and long service life. As a dry vacuum pump, claw vacuum pump can be used in semiconductor, chemical industry, nuclear industry, film, instrument, medicine, biopharmaceuticals, food and other fields, and can be used as a gas delivery pump.
