Problems solved by technology

The filter elements used in traditional oil-bath air filters are usually made of galvanized iron wire, which is usually wound and formed. It is difficult to ensure uniform winding and low production efficiency; the specificity of galvanized iron wire is large, resulting in heavy air filter; The filter, under partial load conditions, has a filtration efficiency of only 87%-93%, and is prone to oil loss; the traditional oil-bath air filter is suitable for low air flow, and cannot meet the requirements of high-power heavy-duty diesel trucks

Abstract

The invention relates to an efficient oil bath type air filter which comprises a filter casing, an upper end cover, a lower end cover, a clamp, an air inlet cavity, a filter core, an air outlet arranged on one side of the upper portion of the filter casing and an oil storing disc arranged in the lower end cover. The filter core is made of a polyurethane material and comprises an upper filter core and a lower filter core which are sequentially sleeved on the outer side of the air inlet cavity in the filter casing, wherein the upper filter core comprises a primary upper filter core and a secondary upper filter core, and an expansion cavity is arranged between the primary upper filter core and the secondary upper filter core. The efficient oil bath type air filter is simple and compact in structure and reliable in sealing, a user can use and operate the efficient oil bath type air filter conveniently, operation environment of an engine can be effectively improved, and the service life of the engine can be prolonged greatly.

Description

technical field [0001] The invention relates to a high-efficiency oil bath air filter. Background technique [0002] In order to prolong the service life of automobile engines and reduce the dust-holding load of paper air filters, the air intake systems of trucks and construction machinery with generally harsh working environments have a first-stage oil-bath air filter in front of the paper air filter. filter. The oil bath air filter has a simple structure, and oil and oil wire are the main filter materials. The oil bath air filter uses the airflow to hit the oil surface, the viscosity of the oil absorbs the impurities in the air, and at the same time, the airflow plays the role of splashing oil, and the oil mist generated wets the filter element. When the air passes through the filter element, the impurities in the air are stuck Connected to the filter element to achieve the effect of filtration and play the role of coarse filtration. The filter elements used in traditio...
