First of all, what is a machine filter?

First of all, it is important to know that when the engine is running, it is in a high-temperature environment, so oxidizing substances, water, metal wear, dust, and so on will constantly enter the oil through operation. The oil filter plays the role of filtering these impurities to keep the lubricating oil clean, thus extending the oil's service life. Therefore, the performance of the oil filter must meet the characteristics of high filtration power, high flow resistance, long service life, etc.

Secondly, what is the role of the machine filter?

The machine filter can filter oil impurities at the bottom of the oil. And it supplies oil to the crankshaft, connecting rod, camshaft, supercharger, and piston ring cleaning.

Thirdly, the structure of the filter

According to the structure of the filter: variable type, rotating type, centrifugal type; Depending on the configuration of the engine system, it can be divided into: full flow, separate type. The filtering technological materials used in oil filters include filter paper, felt, metal mesh, non-woven materials, etc.

Fourthly, the characteristics of the material used in the filter

1. Filter paper: the oil filter has higher requirements for filter paper than the air filter, which not only filters impurities but also ensures sufficient flow.

2. Rubber sealing ring: a good rubber sealing ring should be made of special rubber to prevent oil leakage.

3. Reflux inhibiting valve: when the engine is turned off, it prevents the oil filter from drying out; when the engine is restarted, pressure is immediately created to lubricate it with oil.

4. Safety valve: also called side ventilation, is key to protecting the engine from wear in case of an emergency.

Fifth, the filter replacement cycle of the machine

Xiaobian's combined lubricating oils suggest that owners can change the filter every 5000 kilometers or every six months, but some owners will choose to replace it once every long-term 10000 kilometers. The price is also a bit higher. During installation, special attention should be paid first to draining and disposing of the old oil. It is easier to replace the old oil. Just loosen the fastening screw and remove the old oil filter. Put a layer of oil on the new filter sealing ring, and then turn and fix the new filter.
