Oil filter, also known as oil grid. It is used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine.
We have the oil filter for the brand as following: Komatsu; Hitachi; Caterpilliar; Kobelco; Case; Sumitomo; JCB; Volvo; SANY; Liugong; XCMG; XGMA and so on.
Oil filter, also known as oil grid. It is used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine.
Oil filters are available in full flow and split flow. The full-flow filter is connected in series between the oil pump and the main oil passage, so that all the oil entering the main oil passage can be filtered. The split type cleaner is connected in parallel with the main oil passage to filter only part of the lubricating oil sent by the oil pump.
● Filter paper: The oil filter requires higher filter paper than the air filter, mainly because the temperature change of the oil varies from 0 to 300 degrees. Under the severe temperature change, the oil concentration also changes accordingly. Will affect the filtration flow of the oil. The filter paper of a high-quality oil filter should be able to filter impurities under severe temperature changes while ensuring sufficient flow.
●Rubber seal: The filter seal of high-quality oil is made of special rubber to ensure 100% oil leakage.
● Reflow suppression valve: only available in high quality oil filters. When the engine is turned off, it prevents the oil filter from drying out; when the engine is re-ignited, it immediately generates pressure and supplies oil to the engine. (also known as check valve)
● Overflow valve: Only available in high quality oil filters. When the external temperature drops to a certain value or when the oil filter exceeds the normal service life, the relief valve will open under special pressure, allowing unfiltered oil to flow directly into the engine. Despite this, the impurities in the oil will enter the engine together, but the damage is much smaller than the damage caused by the lack of oil in the engine. The relief valve is therefore the key to protecting the engine in an emergency.
Under normal circumstances, the various components in the engine are lubricated by the oil to achieve normal operation, but the metal debris generated during the operation of the components, the incoming dust, the carbon deposits oxidized at high temperatures, and some of the water vapor will continue to mix. In the oil, the service life of the oil will be reduced for a long time, and in severe cases, it may affect the normal operation of the engine.
Therefore, the role of the oil filter at this time is reflected. Simply put, the role of the oil filter is mainly to filter most of the impurities in the oil, to keep the standby oil clean and prolong its normal service life. In addition, the oil filter should also have the characteristics of strong filtration capacity, low flow resistance and long service life.
For the oil filter, it is used for the construction machines as following brand:
CATERPILLAR, KOMATSU,VOLVO,HITACHI,HYUNDAI,DOOSAN,FIAT-HITACHI,JCB,KOBELCO,SUMITOMO,KATO,CASE,MITSUBISHI,TATA-HITACHI,NEWHOLLAND,JOHN-DEER,KUBOTA, LIEBHERR, TAKEUCHI,KAWASAKI,SANYI,LIUGONG,XCMG,SHANTUI,ZOOMLION;
There are many types of generator sets, and there are different types of generator sets according to different standards. 1. Divided by power source: diesel generator sets, gas generator sets, gasoline generator sets, wind generator sets, solar generator sets, hydroelectric generator sets, coal-fired generator sets, etc. 2. Electric energy mode: According to the converted electric energy mode, i...more
