KT Series High Vacuum Oil Diffusion Vacuum Pump

Jun. 08, 2020

KT series high vacuum oil diffusion pump is the main equipment to obtain 10-1 ~ 10-5 Pa high vacuum and ultra-high vacuum. It has the advantages of low height, small volume and high pumping speed. With internal heating, the pumping speed is higher and the critical front pressure is higher under 10-1Pa pressure.

The structure of diffusion pump is composed of oil heating part (bottom oil pan of expanding pump with electric heater), oil vapor diversion, injection part (all levels of ducts and nozzles), condensation part (pump wall and water jacket) oil observation window (oil outlet, oil outlet, temperature measuring mouth).

It is widely used in vacuum coating, vacuum furnace, electronics, chemical industry, aviation, metallurgy, aerospace, materials, bio medicine, atomic energy, space exploration and other high-tech fields.

Cleaning, oil changing, refueling and temperature measuring of diffusion pump

 

1. Cleaning: After using the diffusion pump for a period of time, it should be cleaned.

 

Note: In the cleaning process must not be cotton fiber hanging in the pump body.

 

2. Refueling: Refueling according to regulations to ensure the quality of oil. Dalian 3 # Diffusion Pump Oil or Silicone Oil.

 

3. Temperature measurement: The temperature measuring mouth is on the top of the oil window. Insert the thermocouple into it. Make sure the threads are screwed tightly and fixed. Every time the thermocouple is replaced (including moving), the temperature feedback of oil temperature signal should be re-determined (the thermocouple should be inserted to the end, not suspended). The thermocouple screw thread is M12 x 1.5.

 

4. Oil discharge: When oil is discharged from the outlet, the new cushion must be replaced.
