The oil filter plays an irreplaceable role in the construction machinery oil circuit: a small oil filter seems to be inconspicuous, but it has an irreplaceable position in construction machinery. Machinery does not start to oil, just like the human body can not be separated from healthy blood, life will be seriously threatened if the body loses too much blood or the blood changes qualitatively. The same is true for the machine. If the oil in the engine does not pass through the filter and directly enters the lubricating oil circuit, the impurities contained in the oil will be brought into the friction surface of the metal to accelerate the wear of the parts and reduce the service life of the engine. Changing the oil filter is extremely simple, but the correct method of operation can extend the life of the machine.

1. The appearance of good machine filter must look good

The machine filter produced by well-known brands is not only good in materials and workmanship, but also not sloppy in the handling of details. Only famous brands are willing to invest in the details of the details to achieve the best, cottage filter or refurbished machine Filtering does not have this ability at all, and it is too lazy to do it well.

The method of “filtering by appearance” is actually very useful, because good machine filtration must have a good appearance. The source of the cheap machine filter itself is very suspicious. Their predecessor may be the used waste machine filter, re-assembled and re-sold through refurbishment, and of course the process can save the province.

2. Look at the filter rubber ring for toughness and softness

The rubber ring that filters the filter into and out of the oil outlet is also one of the references for judging the filter. You can take off the rubber ring and squeeze it by hand to feel the texture of the rubber ring.

Good machine filter, the material of the rubber ring will be very thick, and there will be a soft feeling when pinching by hand to ensure the tightness around the oil inlet and outlet.

3. See if there is a check valve structure inside

Whether or not there is a check valve is also an important basis for judging the level of a machine filter quality. You can use the gadgets around you to identify whether the filter has a check valve structure.

The machine filter check valve is actually a rubber cup, a very simple one, but the effect is very important – it can block the oil return, to ensure that the engine can be formed in the lubrication system as soon as possible during the cold start of the engine. Oil, as much as possible to shorten the engine dry grinding time.
