The oil filter, as the name suggests, plays a role of filtering and cleaning. If you just think so, it is far from enough. The quality of the filter is directly related to the engine’s power output performance, engine durability and fuel consumption rate. Harmful substances (metal abrasive particles, dust, sludge, etc.) produced by the engine during operation will affect the engine. In order to make the lubricating oil flow smoothly, the oil filter prevents impurities from scratching and roughening the surface of the parts. The oil is being delivered. Before rubbing the surface, it must be strictly filtered.
However, the oil will clean and dissolve the impurities generated and then flow back to the oil pan. After re-filtering, the oil filter will work to filter out harmful impurities in the oil from the oil pan. The filtered oil is supplied to the crankshaft. , Connecting rod, camshaft, supercharger, piston ring and other motion pairs, play the role of lubrication, cooling and cleaning, thereby extending the life of parts. Therefore, it is recommended to replace the oil filter together with oil maintenance.
Generally, the lubrication system of an engine will be equipped with several filters of different capabilities—collector, coarse filter and fine filter, which are respectively connected in parallel or in series in the main oil passage of the engine. The oil filter structure mainly includes filter paper, rubber sealing ring, backflow suppression valve, overflow valve, etc.
Bypass valve: also known as the overflow valve, when the external temperature drops to a certain value or when the oil filter exceeds the normal service life, the overflow valve will be opened under special pressure to allow the unfiltered oil to flow directly Into the engine.
Nevertheless, the impurities in the oil will enter the engine together, but the damage is much smaller than the damage caused by the absence of oil in the engine. Therefore, the overflow valve is the key to protect the engine in an emergency.
Filter paper: It is the key to the oil filter. The requirements are particularly high. The main reason is that the temperature of the oil varies from 0 to 300 degrees. Under severe temperature changes, the concentration of the oil will also change accordingly, which will affect the oil. Filter traffic. The filter paper of a high-quality oil filter must be able to filter impurities under severe temperature changes while ensuring sufficient flow.
Check valve: also known as the backflow suppression valve, when the engine is turned off, it can prevent the oil filter from drying out; when the engine is re-ignited, it immediately generates pressure to supply oil to lubricate the engine.
Sealing rubber ring: A sealing ring made of special rubber to ensure 100% oil leakage.
As a common consumable for trucks, filter technology has continued to innovate and the structure has been optimized. However, the best product structure is still inseparable from the reasonable maintenance of the driver and friends. Observe and pay more attention during the daily driving process, and the maintenance is due. Only in this way can the truck be safe and efficient, and the engine will be durable, thereby reducing the overall transportation cost of drivers and friends.
GHL oil filter has clear texture, good paper material, uniform density, strong resistance to pressure, and good oil flow. After a long time of oil bubble, it will not be deformed or blistered. Inferior filters can’t do this.
