Vacuum coating is widely used in various industries, including machinery, electronics, hardware, aerospace, medical, chemical and other fields, so what is the difference between before and after PVD coating, and where is it reflected? So many industries are using it and there must be a reason for...

The replacement of vacuum pump oil does not mean simply draining the vacuum pump oil and then injecting new pump oil. When replacing the pump oil, pay attention to the cleaning of residual impurities in the pump. After the vacuum pump has been used continuously for 3 to 4 months, the vacuum pump...

After nearly 40 years of development in vacuum degassing, the refining function has been continuously expanded, and it has changed from a simple degassing device to a multi-functional processing device. Its fast processing feature enables it to cooperate with the fast pace of the converter. The v...

Magnetic levitation molecular pump products are the key core components of integrated circuit manufacturing equipment, providing the required high cleanliness and ultra-high vacuum environment for key semiconductor manufacturing processes such as process etching, ion implantation, and thin film d...

Many devices generate magnetic fields when they work. For example, the magnetic field strength of a household refrigerator is about 10 Gauss (1mT), and the magnetic field strength of an MRI (nuclear magnetic resonance) can even be as high as 3T; although measures such as shielding can be taken, t...

1、 What is emulsification? From the point of view of physics, it can be understood that the phenomenon that two liquids that could not be mixed together could be mixed together due to the effect of surfactant is called emulsification. 2、 Reasons for emulsification of vacuum pump oil During ope...

In order to ensure that the vacuum equipment or system has a good sealing performance, it is far from enough to find the location of the leak after the installation of the equipment and block the channel of the leak. It is necessary to conduct vacuum leak detection at any time during the design, ...

In the context of the continuous expansion of the pharmaceutical industry and the continuous progress of vacuum pump technology, the market prospect of piston vacuum pump is broad, and the competition among manufacturers is also becoming more and more fierce. According to the industry, during the...

Vacuum Gauge is an instrument that measures vacuum or air pressure. Generally, the changes in a certain physical effect under different air pressure are measured for air pressure. Widely used in scientific research and industrial production. According to the different physical mechanisms used in ...

The sealing device of the pump is mainly divided into two categories: one is static seal, and the other is dynamic seal. Static seals usually have gasket seals, O-ring seals, thread seals and other types. Dynamic seals mainly include soft packing seals, oil seal seals, labyrinth seals, screw seal...
