How does the oil filter eliminate foam in lubricating oil?

The self-excited vibration defoaming technology of vacuum oil filters is widely used in high vacuum oil filters. The self-excited vibration defoaming system of high vacuum oil filter consists of a spray device, an atomizing device, a self-excited vibration defoaming device, a reaction tower, a separation tower, a separation chamber, a separation sieve tower, a vacuum chamber and an oil collection tank.

The vacuum separation kettle is the key technology for vacuum oil filter separation. It includes a vacuum separation kettle tank body. The top of the vacuum separation kettle tank body is provided with an oil inlet and an air intake port, and the bottom is provided with an oil outlet and a check valve. The upper part of the vacuum separation kettle tank body has an atomization chamber corresponding to the oil inlet. Several downward spraying nozzles are provided at the bottom of the atomization chamber, and a separation tower is provided below the nozzle. The bottom of the separation tower is elastically connected to the inner wall of the vacuum separation kettle tank body through an elastic connecting piece, and a separation net is provided in the separation tower.

This new type of high vacuum oil filter self-excited vibration defoaming system has high dehydration and degassing efficiency and fast gas-liquid separation speed through self-excited vibration. With the self-excited vibration defoaming technology, the vacuum oil filter has a long-term working electronic vacuum gauge measurement value of -70Pa without foam rising in the vacuum tank.

Core technology of the vacuum oil filter

New vacuum oil filter self-excited vibration defoaming system: ≤-70Pa test runs continuously for 168 hours without foam rising.

Working vacuum degree: ≤-70Pa When filtering oil for a long time, the air intake is not used to reduce the vacuum or the manual valve is not used to destroy the vacuum degree to eliminate the foam in the vacuum reactor, to achieve the purpose of no oil leakage.

Ultimate vacuum degree: reach the limit ≤-10Pa

Oil filter working vacuum degree requirement: ≤-70Pa-133Pa. When filtering oil for a long time, there will be no foam rising in the vacuum reactor. The self-excited vibration defoaming system technology is used to ensure that the oil filter works in a high vacuum state without oil leakage. When the foam of the vacuum reactor rises, it is not allowed to reduce the vacuum degree by entering the atmosphere to eliminate the foam.

As the name implies, the vacuum oil filter requires vacuum. The higher the vacuum degree, the faster the dehydration and gas drying. On the contrary, the oil filter is energy-saving and the oil filtering speed is fast.

What are the backward defoaming methods of the vacuum oil filter?

At present, low-priced, low-priced, backward vacuum oil filter manufacturers on the market usually use infrared defoaming devices, proximity switches, capacitive switches, oil bubble sensors, etc., thereby reducing the vacuum and achieving the purpose of defoaming. The air intake of the solenoid valve gives a signal through the switch to reduce the vacuum, thereby achieving the purpose of defoaming, and is widely used in special low-end oil filters. However, during the defoaming process, the vacuum degree will be reduced, which is time-consuming and power-consuming, not energy-saving and environmentally friendly, and the oil purification effect cannot be achieved in a short time.
