Vacuum pump oil mist separator is also known as vacuum pump oil mist filter and oil-gas separator. The working principle is as follows: the oil-gas mixture discharged by the vacuum pump enters the oil mist separator from the exhaust port, and passes through the filter material of the filter element under the push of the exhaust pressure. At this time, the fine oil molecules are captured by the glass fiber filter paper, and the gas passes through the finer holes of the glass fiber filter paper.
As the mixture of oil and gas continues to flow outward, more and more oil molecules are captured and pushed outward by the exhaust pressure, and the small oil molecules coalesce into large oil particles, which drip into the tank due to gravity after being squeezed out of the filter element. Relatively clean gas is discharged out of the pump and oil is trapped, thus realizing the separation process of gas and oil.
The filtered vacuum pump oil is recycled along with the oil return pipe, and oil-free waste gas is discharged, so as to achieve pollution-free and clean effects.
