Primary filterThere are three styles of plate type, folding type and bag type. The outer frame materials include paper frame, aluminum frame, and galvanized iron frame. Filter materials include non-woven fabric, nylon mesh, activated carbon filter material, metal mesh, etc., and the protective net has double-sided Plastic sprayed wire mesh and double-sided galvanized wire mesh.

Add filter cotton before the primary filter, and fix the four corners on the primary air filter. The problem is solved. The principle is that due to negative pressure, the filter cotton is naturally adsorbed on the primary air filter, and the filter cotton is cleaned regularly to reduce the number of primary cleanings. After adding filter cotton, it is necessary to follow up and investigate whether the program has an impact on the air supply volume and filtering effect of the air conditioner.

The water enters from the inlet, and the coarse filter is used to filter the large particles of impurities before reaching the fine filter. During the filtration process, the fine filter gradually accumulates impurities in the water to form an impurity layer of the filter. The impurity layer accumulates on the inside of the fine filter, and the pressure difference between the inside and outside of the fine filter is formed. When the pressure difference of the filter reaches the preset value, the automatic cleaning process will start. During this period, the supply of clean water is continuous, the cleaning valve is opened, the water pressure in the cleaning chamber and the suction device drops significantly, passing the pressure of the filter cartridge and the suction pipe Poor, the suction nozzle generates a suction force between the suction pipe and the cleaning chamber, forming a dirt suction process. At the same time, the motor drives the suction pipe to make an axial spiral movement. The combination of axial movement and rotating movement of the dirt suction device cleans the entire inner surface of the filter screen completely. The entire cleaning process only takes tens of seconds. The drain valve is closed at the end of cleaning. The knowledge points of the backwashing primary filter begin to prepare for the next washing cycle.               Mobile: 13355281100
