High vacuum oil diffusion pump unit

High vacuum oil diffusion pump unit profile:
The high vacuum pumping unit uses the Rots rotary vane unit as pre-pumping. Both the diffusion pump body and the baffle plate are improved, making the pumping speed greater in the lower vacuum area.


High vacuum oil diffusion pump unit


First, the characteristics and use of diffusion pump unit:
 The oil diffusion vacuum pump unit is the main equipment used to obtain high vacuum (10-2 to 10-5Pa). It is composed of oil diffusion pump as the main pump and valve, water-cooled baffle, pipeline, mechanical vacuum pump (pre-stage pump) and other components to form a high-vacuum pumping system. The characteristics of this unit is that the pumping capacity is large and the pumping speed is from 240L/s. It can be selected up to 60,000 L/s; it can work stably for a long time.
It is widely used in electronics, chemical, metallurgy, aerospace, aerospace, materials, biomedicine, atomic energy, cosmic exploration and other high-tech fields. Such as various vacuum furnaces, vacuum coating equipment, vacuum freeze-drying equipment.
