High Vacuum Oil Diffusion Pump production process

High Vacuum Oil Diffusion Pump is a commonly used vacuum pump that achieves vacuum extraction by utilizing oil vapor to diffuse in the diffusion pump and be absorbed by gas molecules.

The pump has high pumping speed, high ultimate vacuum and wide application range, and is widely used in semiconductor, electronics, instrumentation, vacuum metallurgy and other fields.

Some common applications include: manufacturing microprocessors and integrated circuits, producing solar cells and photovoltaic modules, producing LED displays, vacuum melting and electron beam welding, etc.

The production process of High Vacuum Oil Diffusion Pump is as follows:

Preparing the pump casing: The pump casing is usually made of stainless steel and needs to be processed, polished and cleaned.

Prepare the air extraction system: The air extraction system includes the pump body, exhaust valve, helium intermediate pump, cooler, water circulation system, etc.

Prepare the diffuser: Diffusers are usually made of glass and require heating, polishing and other processes. The diffuser should be consistent with the sealing surface of the pump casing and adhered to the sealing surface of the pump casing.

Install heater: The heater of the pump body needs to be installed in the pump body to heat the oil in the pump.

Install a disposable safety valve: To ensure operator safety, a disposable safety valve is necessary. During production, the safety valve must be connected to the exhaust valve.

Oil filling: Filling with heat pump oil. The medium of heat pump oil and air extraction method is the same.

Testing and debugging: Testing and debugging are required after completion of manufacturing to ensure the stability and normal function of the High Vacuum Oil Diffusion Pump.

The above is the production process of High Vacuum Oil Diffusion Pump, which requires professional craftsmen to operate.
