Vertical roots pump
Vertical roots vacuum pump is a volumetric vacuum pump, similar to the horizontal roots pump, can not be used alone. As currently available in one of the main extraction equipment, high vacuum pump, the working principle are similar to those of roots blower, is to use two figure 8 rotor synchronous rotation in the pump shell, to complete the suction, exhaust and then create a vacuum.
Vertical roots pump widely used in vacuum coating, vacuum drying, vacuum smelting, vacuum welding, vacuum coating, metallurgical industry, aviation simulation, chemical, food, pharmaceutical, oil refining system dehydration system, chemical evaporation, distillation, concentration, low temperature cooling system, etc., is a kind of wide application of roots pump.
Adopt high technology to realize zero leakage. It avoids the leakage, unstable work, short service life and high maintenance cost of ordinary oil seal vacuum pump.
2. In order to apply to contain a large amount of water vapor and organic solvent environment (e.g., chemical, pharmaceutical, etc.), we have improved, such as gear box and adopts composite seal between the vacuum chamber, in order to realize oil-free pump cavity, so as to avoid the oil vapor pollution vacuum system, avoid the happening of the oil emulsion.
3. It is very suitable for the vacuum unit with water ring vacuum pump and other front stage pumps.
4. The vacuum degree covers a wide range and can have a large pumping speed in a wide range of pressure (1x10-2 ~ 1x10, 2 mbar).
5. Use frequency conversion to start, reduce the start impact, the vibration small movement is stable, the noise is small.
6. Small loss of mechanical friction and low power of motor.
7. The pump has stable performance, long service life and small maintenance cost.
