When the engine is running, a small part of the oil is pumped from the oil pump and enters the filter through the oil port. Then it enters the rotor body through the oil hole and ejects from the two nozzles, so the ejection reaction force pushes the rotating hand to rotate. Under the action of the rotating centrifugal force, they are thrown to the rotor wall, and Attach the cover to the wall.

When the oil pressure is lower than 9s kPa, the oil inlet pressure limiting valve is closed and the fine filter does not work. When the oil pressure rises to 294 kPa, the speed of the rotor can reach 5000r/min or more, and the specific gravity of impurities in the lubricating oil in the rotor cavity is larger than that of the lubricating oil.When the oil pressure exceeds 98 kPa, the pressure limiting valve is gradually opened, and the oil is sprayed from the oil outlet through the center hole of the rotor shaft.

It is connected to the oil inlet of the oil pump. Float type oil filter, in order to make the oil pump work well, the large particles in the lubricating oil must be removed before entering the oil pump. A compression nut fastens the rotor cover and the rotor body together. In order to achieve a satisfactory filtering effect without increasing the resistance of Casting Automotive Mould Manufacturers the oil passage, the coarse filter is generally connected in series with the main oil passage, and the fine filter is connected in parallel with the main oil passage. The clean lubricating oil at the center enters the two nozzles from the center and continuously sprays outward, and the sprayed lubricating oil flows back to the lower crankcase.

It is mainly composed of upper cover, shell, paper filter element and bypass valve. parts-its function is to filter out smaller impurities in the lubricating oil. When the oil pump is working, the oil is sucked in from the slit between the cover and the float, filtered through the filter screen to remove coarse impurities, and then enters the oil pump through the oil pipe welded to the float.
