The process is to use the force generated by the pressure difference between the vacuum and the atmosphere to transport materials, forming the gas flow in the pipeline, driving the movement of powdery materials, so as to complete the transportation of powder.

Applicable products: Roots vacuum unit, dry screw vacuum pump, rotary vane vacuum pump and other pumps.

The process is to evaporate and cool the excessive saturated liquid to form a crystal, so that the evaporation and cooling rate can be controlled by adjusting the pressure, and the cost can be reduced by reducing the boiling point of the liquid.

Applicable products: Roots vacuum unit, dry screw vacuum pump, rotary vane vacuum pump and other pumps.

This process is one of the common methods of separating and purifying compounds, especially for the separation and purification of substances with high boiling points and those compounds that have been decomposed, oxidized or polymerized by heat before reaching boiling point during atmospheric distillation.

Applicable products: Roots vacuum unit, dry screw vacuum pump, rotary vane vacuum pump and other pumps.

The process is to reduce or oxidize biological products by increasing the vacuum degree to reduce the boiling point of the material, evaporating the liquid from the solid, so that the biological components or active ingredients are not destroyed.

Applicable products: Roots vacuum unit, dry screw vacuum pump, liquid ring vacuum pump and other pumps.

Experimental equipment between laboratory and industrial production scale, experimental equipment used to conduct basic research to demonstrate the feasibility of the process and determine the safety amplification factor, the basic constancy of the process or process design, and reduce and avoid the risks encountered in process development.

Applicable products: Roots vacuum unit, dry screw vacuum pump, rotary vane vacuum pump, liquid ring vacuum pump and other pumps.

It refers to the test to verify the performance and function of spacecraft and its components under vacuum and certain temperature conditions, which consists of cold immersion, hot immersion and temperature change process.

Applicable products: Roots vacuum unit, dry screw vacuum pump, rotary vane vacuum pump and other pumps.

The process is to use physical methods to produce deposited films, namely evaporation coating, sputtering coating and ion plating, in the vacuum chamber, the atoms of the material are isolated from the heating source and hit the surface of the plated object.

Applicable products: dry screw vacuum pump, slide valve vacuum pump, diffusion pump, rotary vane vacuum pump, Roots vacuum unit and other pumps.

This process is a newly developed epitaxial film making method, which is a method to grow the film layer by layer along the direction of the crystal axis of the substrate material under appropriate substrate and appropriate conditions.

Applicable products: dry screw vacuum pump, slide valve vacuum pump, diffusion pump, rotary vane vacuum pump, Roots vacuum unit and other pumps.
