Hawach Scientific co., LTD, Since its establishment, Hawach has always carried out the business purpose of “credibility and development, quality and survival” and the business philosophy of “customer first”.
The vacuum diaphragm pump is designed according to the principle of volume pump. When the motor drives the connecting rod to move up and down, it drives the diaphragm to open and close, changes the volume of the diaphragm chamber, changes the pressure of the medium, and achieves inhalation and discharge.
In recent years, with the rapid development of economy, the vacuum pump-related downstream application industry has maintained a rapid growth momentum. At the same time, with the continuous expansion of vacuum pump application fields and other factors, the vacuum pump industry has achieved sustained and steady development.
Vacuum pump oil
The vacuum pump is one kind of vacuum filtration in HAWACH, in addition to the vacuum device. We’ve been discussed the advantages of the HAWACH vacuum pump before, like high work efficiency, long service life, and easy & safe operation, so today’s focus is on the maintenance of the vacuum pumps, especially its lubricating oil.
In the vacuum pump, the vacuum pump oil not only acts as a medium for obtaining vacuum but also lubricates, cools and seals the mechanical friction points. As the vacuum pump requires high vacuum, paraffin-based narrow-cut lubricating oil is generally used. For diffusion vacuum pump, silicone oil or other synthetic oil with low vapor pressure can be used.
