Manufacturing semiconductor chips must be carried out in a vacuum environment, which can avoid oxidation and pollution, and ensure chip quality and performance. At normal temperature and pressure, the environment contains a large number of impure sub...

Supervacuum has the following significant characteristics: 1. Very low pressure In a supervacuum, the pressure can be incredibly low, much lower than in a normal vacuum environment. This extremely low pressure makes ultra-vacuum an ideal environment ...

Working principle A vacuum pump is a device used to expel gas molecules from an enclosed space, thereby creating a vacuum environment. Its working principle is mainly based on different physical mechanisms. 1, volume change principle Common rotary va...

Performance of sealing The sealing performance of the valve refers to the ability of the sealing parts of the valve to prevent the leakage of the medium, which is the most important technical performance index of the valve. There are three sealing pa...

The linkage between vacuum pump and vacuum valve plays an important role in vacuum system. The vacuum pump is used to generate and maintain the required vacuum, while the vacuum valve is used to control the flow and pressure of the gas and ensure the...

A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container to obtain a vacuum. Simply put, a vacuum pump is a device that uses various methods to improve, generate, and maintain a vacuum in a closed space.
