Product Description
Air filter refers to a device that removes particulate impurities in the air. When piston machinery (internal combustion engine, reciprocating compressor air filter, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so an air filter must be installed. The air filter is composed of a filter element and a shell. The main requirements of air filtration are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance. Classification: The engine has three kinds of filters: air, oil, and fuel. The air-conditioning filter in the car is generally called "four filters". They are respectively responsible for the filtration of media in the engine air intake system, lubrication system, and combustion system cooling system. A. The oil filter is located in the engine lubrication system. The upstream of it is the oil pump, and the downstream are the parts of the engine that need to be lubricated. Its function is to filter out harmful impurities in the oil from the oil pan, and supply the crankshaft, connecting rod, camshaft, supercharger, piston ring and other motion pairs with clean oil for lubrication, cooling, and cleaning. Extend the life of these parts. B. Fuel filters are divided into carburetor and electronic injection. For gasoline engines using carburetor, the fuel filter is located on the inlet side of the fuel transfer pump, and the working pressure is relatively small. Generally, nylon shells are used for electronic injection engines. The fuel filter is located on the outlet side of the fuel transfer pump and has a higher working pressure, usually with a metal casing. C. The car air filter is located in the engine air intake system. It is an assembly composed of one or several clean air filter components. Its main function is to filter out harmful impurities in the air that will enter the cylinder to reduce the early wear of the cylinder, piston, piston ring, valve and valve seat. D. The car air conditioner filter is used to filter the air in the car compartment and the air circulation inside and outside the car compartment. Remove the air in the cabin or the dust, impurities, smoke odor, pollen, etc. that enter the air in the cabin to ensure the health of passengers and remove the peculiar smell in the cabin. At the same time, the air-conditioning filter also makes the windshield difficult to atomize| Brand: | Donaldson |
