Weichai Engine Parts

The function of Weichai engine parts of filter: To filter out harmful particles and water in the engine fuel gas system to protect oil pump nozzles, cylinder liners, piston rings, etc., reduce wear and avoid blockage.
Principle of Weichai engine parts of filter: When the diesel engine is working, the diesel oil is filtered by the diesel precipitator after coarse filtration, and then filtered by the special paper filter element in the diesel filter in two stages for oil supply. The filter element material is made of imported filter paper, so it has high filtration efficiency, low flow resistance, and can filter out some corrosive impurities to reduce the damage of fuel system parts and improve the quality of diesel fuel itself, so as to guarantee the best performance and service life of the engine.

The function of Weichai engine parts of water pump: Its role is to pump the coolant, so that the coolant in the engine’s cooling water channel fast flows to take away the heat generated by the engine work, to maintain the normal working temperature of the engine.
Principle of Weichai engine parts of water pump: The pump bearing and impeller are driven by the pulley to rotate, and the coolant in the pump is driven by the impeller to rotate together and is thrown to the edge of the pump shell under the action of centrifugal force while generating a certain pressure, and then flows out from the outlet waterway or water pipe. The pressure at the center of the impeller is reduced because the coolant is thrown out, and the coolant in the water tank is sucked into the impeller through the water pipe under the action of the pressure difference between the pump inlet and the center of the impeller to realize the reciprocal circulation of coolant.
