working principle：
Roots vacuum pump, also known as mechanical booster pump, is a rotary volumetric vacuum pump. Two figure-eight rotors maintain a certain gap with the pump cavity. When the two rotors rotate in the pump cavity through a pair of synchronous counter-rotating gears Do not touch each other and maintain a certain gap. The figure on the right is the structural principle diagram of the pump. From Figure I to Figure IV, the rotor rotates in the pump cavity and completes the process of suction and exhaust.
Features：
*High speed and high volumetric efficiency;
*Simple structure, convenient operation and maintenance;
*The rotor is locked and there is no axial string movement phenomenon;
*Using high-precision transmission gears, SKF high-precision bearings and good dynamic balance to ensure low noise and stable operation of the product;
*It adopts balanced stainless steel mechanical seal, and the pump chamber is an oil-free mechanism, which is suitable for pumping general gas and various special gases;
*Compared with other mechanical vacuum pumps, the energy saving effect is remarkable;
*It can be matched with various backing pumps and can be widely used in various process ranges.
Application range:
The advantage of a roots vacuum pump is that it still has a larger pumping rate at a lower inlet pressure, but the roots vacuum pump cannot be used alone, and must be used in conjunction with the fore vacuum pump. The roots vacuum pump can only be started when the current stage vacuum pump pumps the system pressure to the allowable starting pressure of the roots vacuum pump.
According to different working pressures and process conditions, the fore vacuum pumps of Roots vacuum pumps can be screw vacuum pumps, liquid ring vacuum pumps, slide valve vacuum pumps, etc. After configuring different types of backing vacuum pumps, the ultimate pressure that the roots vacuum pump can reach is different.
Roots vacuum pumps can be widely used in any vacuum system that requires high pumping speed and medium vacuum (10-1--10-2Pa), such as: vacuum coating, vacuum welding furnace, vacuum heat treatment furnace, large space simulation experiment, lamp tube And bulb manufacturing, laser manufacturing, vacuum packaging equipment, automobile manufacturing, centralized vacuum exhaust system, various chemical processing, vacuum degassing, vacuum degassing, vacuum dehydration, vacuum freeze drying, vacuum distillation, etc.

Note:
1. The pumping rate refers to the maximum pumping rate measured with the inlet pressure of the Roots vacuum pump in the range of 2.67pa~67pa under the condition of using the recommended backing pump.
2. The ultimate pressure refers to the stable value measured at the inlet of the pump with a compression vacuum gauge after sufficient air extraction without any additional container, without any additional container, and no air intake. The lowest value of air partial pressure.
3. The performances in the above table are obtained under the condition of using the recommended foreline pump. Users can choose different foreline vacuum pumps according to different conditions, but their main performance indicators will vary.
