Vacuum diffusion pump oil is an indispensable and important element in vacuum technology, especially in the field of high vacuum, it plays a vital role. As the core working medium of the diffusion pump, vacuum diffusion pump oil not only affects the performance of the pump, but also directly relates to the stability and reliability of the entire vacuum system.
The working principle of the diffusion pump relies on the high-speed ejection of steam jets, and the vacuum diffusion pump oil is the source of steam in this process. In the pump chamber, the oil is heated to boiling and converted into steam, which is then ejected at high speed through the nozzle to form a low-density, high-speed steam jet. This jet not only carries and discharges the pumped gas, but also ensures the efficient operation of the vacuum system.
High-quality vacuum diffusion pump oil has extremely low saturated vapor pressure and extremely high ultimate vacuum, which means that it can remain stable over a wider range of temperature and pressure, thereby providing a lasting vacuum environment. In addition, good oxidation resistance, thermal stability and chemical stability are also important characteristics of high-quality pump oils, which help reduce the failure rate and maintenance costs of the pump and extend the service life of the pump.
In practical applications, it is crucial to choose the right vacuum diffusion pump oil. Users need to determine the specifications and models of pump oil according to the specific needs of the vacuum system and the type of pump. At the same time, regular replacement of pump oil, keeping the pump cavity clean, and correct use and maintenance are also the key to ensure the stable operation of the vacuum system.
In short, as the core medium of high vacuum technology, the performance and quality of vacuum diffusion pump oil are directly related to the stability and reliability of the vacuum system. With the continuous advancement of science and technology and the continuous expansion of application fields, vacuum diffusion pump oil will continue to play an important role in the high-tech industry.
