The difference between vacuum oil filter and centrifugal oil filter

The difference between vacuum oil filter and centrifugal oil filter

1. Vacuum oil filter and centrifugal oil filter are oil filters, which can filter oil impurities and moisture, but there are many differences in terms of technology, application scenarios, after-sales maintenance, and price.

2, the first is the difference in the principle of oil filter technology, vacuum oil filter uses vacuum flash to filter water, emulsification, degassing, acid reduction, use of filter core to intercept impurities, decolorization by adsorbent, etc.; and centrifugal oil filter The machine uses centrifugal force to generate centrifugal force to “crack out” impurities and water. The principle of washing water is exactly the same. The filtration precision is not very high. It can quickly filter a large amount of water and impurities, but it cannot filter a small amount of water. Emulsification, inability to remove gas, and inability to reduce acid value. For industrial oils with high cleanliness and water content and gas content, the centrifugal oil filter has relatively insufficient capacity.

3. The technical principle and basic technical points of the vacuum oil filter and the centrifugal oil filter are analyzed. Therefore, we can know that the vacuum oil filter is mainly used for industrial oil, and the centrifugal type is still used for filtering edible oil. Centrifugal oil filters can also be used in situations where technical requirements such as cleanliness and water content are not high. If the waste oil is emulsified and the acid value is unqualified, then only the vacuum oil filter is used. The centrifugal oil filter cannot be emulsified and reduced in acid value. 4, after the sale of this piece, the centrifugal oil filter is mainly easy to damage the centrifuge and bearings, long-term high-speed operation, high thermal friction, so that the life of centrifugal and related linkage bearings is greatly shortened, once the damage needs to be replaced, the cost is more High, and the oil pump is also prone to problems. Vacuum oil filter is generally a small component such as sensor, liquid level control, filter element, etc. It is easy to damage, and the price is not expensive. In addition, if you buy a poor quality oil filter, the quality of the oil pump and vacuum pump is also easy to damage. The main consumable is the filter element. If it is used with a cleanable filter element, the later cost is still relatively low.

5. Vacuum oil filter and centrifugal oil filter machine With the increase of substitute materials and localization of accessories, the overall price trend is lower, but there are also many sacrifices for quality and low price, and then by not providing after-sales service, high-priced selling accessories Bad companies that make money need to pay more attention when making decisions. The price of the vacuum oil filter is similar to that of the centrifugal oil filter. Due to the specific configuration, flow size, and functional requirements, the price varies greatly. This requires careful understanding by the user. The oil filter is a non-standard machine. The function, structure, pipe diameter and filtration capacity can be customized according to user requirements.
