Mechanical pump

What is mechanical pump?

A mechanical pump, that is, a mechanical vacuum pump, is a kind of machinery that produces vacuum. It can discharge or absorb air in a closed or semi-closed space to achieve a relative vacuum in a local space. Common vacuum pumps include reciprocating vacuum pumps, water ring pumps, molecular pumps, rotary vane vacuum pumps, piston vacuum pumps, swing piston vacuum pumps, diaphragm vacuum pumps, linear vacuum pumps and so on.

Rough pump

Name：H-150 Rotary Plunger Vacuum Pumps

Manufacturer：ZheJiang

Pumping Rate：150L/s

Motor Power：15kw

Quantity：1 set

Feature：

1.It can start pumping from the Atmospheric pressure directly. 

2.The pump can be operated singly. It also can be as a backing pump when combined with another high vacuum pump, such as diffusion pump, oil booster vacuum pump and roots vacuum pump. Series rotary piston vacuum pump can be used 

for a longer time

3.It is widely used in vacuum coating, vacuum heat treatment, vacuum sintering, molecule distilling and space simulation testing in astronomy etc.

4.This vacuum pump is a sort of vacuum production equipment suitable for pumping ordinary gases and a little condensable gas (for example, water vapor) with gas ballast used.

 The pump must be fitted with appropriate accessories if gas is rich in oxygen. Explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.

　　Vacuum  Coating Machine Manufacturers Vacuum Coating Machine is a process in which the material to be filmed is placed in a vacuum for evaporation or sublimation, so that it is deposited on the surface of the workpiece or substrate. (The metal coating in the Vacuum Coating Machine is usually aluminum film, but other metals such as chromium can also be deposited by evaporation; the thickness is about 30um.)

　　The Vacuum Coating Machine process of the vacuum coating machine is as follows:

　　Vacuum  Coating Machine Manufacturers Vacuum Coating Machine is to heat the raw material to be formed into a thin film in a vacuum chamber to vaporize and escape atoms or molecules from the surface, forming a vapor stream that is incident on the surface of a solid (called a substrate or a substrate) to condense to form a solid thin film. Regarding the shape of the evaporation source, according to the nature of the evaporation material, combined with the wettability of the evaporation material, it can be made into different forms and different evaporation source materials can be selected.

　　There are three layers of Vacuum Coating Machine: primer layer (6~12um) + coating layer (1~2um) + top coating layer (10um). Wipe impurities and dust on the surface of the substrate with a cloth to improve the spray yield. Assemble the base material on a special hanger to fix it on the assembly line, and realize the appearance and function of the mask according to the design requirements. Since the substrate is a plastic part, air bubbles and organic gases will remain during injection molding. The surface of the plastic is not smooth enough, and the direct vapor deposition is poorly absorbed and not smooth. Applying a primer will improve the adhesion of the coating and the surface will be smooth and smooth. The pendant is assembled in a vacuum container and heated to realize evaporation.
