Background
Suction filters refer to devices that utilize a vacuum to force a liquid in a fluid through a filter paper to separate solid particles in the fluid. A filter cavity is formed in the suction filter, and filter paper is arranged in the filter cavity. When the filter is used, the vacuum pump is arranged at the outlet of the suction filter, fluid can be pumped into the filtering cavity from the inlet of the suction filter through the vacuum pump, filtered by the filter paper and flows out from the outlet of the filter, and solid particles in the fluid are trapped by the filter paper, so that the fluid is filtered. Currently, there are flat-type, integrated-type and cylindrical-type automatic transmission suction oil filter structures, wherein when a transmission oil pump is operated, a flat-type suction filter works, a liquid inlet of the suction filter is immersed in oil, and an oil pump is installed at a liquid outlet of the suction filter to generate negative pressure so as to realize suction of the oil. The oil enters the filtering cavity of the suction filter from the oil suction port of the suction filter, and after being filtered by filter paper in the filtering cavity, the oil flows out from the liquid outlet and enters the hydraulic system through the driving of the oil pump.
The filter plate in the existing suction filter is generally fixed between the upper shell and the lower shell in a clamping manner, and when the shell cannot be divided into the upper shell and the lower shell due to the special installation position of the filter plate, the filter plate can be directly welded in the shell. The filter plate is required to be welded in the shell, and the sealing cover of the shell is still required to be welded once, so that the cost is too high, and the production efficiency is low.
