How to choose a vacuum pump used ① if cold, difficult to start, an optional low a viscosity grade oil pump. ② If the pump is to work long hours at high pump temperature, such as a pump and the environment in the summer heat and poor ventilation, suction gas is heated or high inlet pressure to work the case, an optional high viscosity grades of high-quality oil or applicable high temperature, high load pump oil, such as HFV-A series of oil. ③ If the pump temperature is high, claw type dry vacuum pump, while demanding full pressure pump limit, such as two-stage pump limit full pressure ≤5 Pa, a viscosity of 100 or 150 can be reelected qualified oil products, or the same or slightly higher viscosity machine oil, compressor oil, mechanical oil prices lower. ④ If a shorter oil change or a short period, but also to meet the performance requirements can be reelected with higher viscosity or viscosity Qualified oil or machine oil, compressor oil, to reduce oil change costs. Specific choose to be decided by the user himself. Ordinary lubricating oil pump and the difference between the name suggests is used in the vacuum pump in the oil, in addition to a general lubricant called lubrication, cooling, anti-oxidation, water separator, etc. characteristics, turbofan vacuum pump, more emphasis is In the low state, much less than the light components of conventional oils, claw vacuum pumps, popular speaking, vacuum pump, is not out of oil and gas to when you vacuum, so, you soon reach the vacuum pump effect , which is not to take away the smoke, the vacuum is always able to come up, which requires oil refining degree higher, when necessary, to choose a synthetic oil!
