Embodiment 1

[0056] In this embodiment, the first aspect provides a testable air filter structure. The structure of the air filter is a comprehensive filtering system, which is composed of a primary filter 2, a secondary filter 9, and a dust extraction device 3. The primary filter is a centrifugal separation filter device, which mainly separates the larger particles in the dusty air from the air by forcing the dusty air to rotate and accelerate; the secondary filter is a paper filter element filter structure, which receives a The air filtered by the first-stage filter is finely filtered, that is, the smaller particles in the air are intercepted, so that the clean air is sent into the engine to ensure the reliable operation of the engine; this structure is also equipped with a dust extraction device to filter the first-stage The dust separated by the filter is drawn out of the dust collection chamber and discharged to the outside of the vehicle, thereby improving the separation efficiency o...

Abstract

The invention belongs to the machinery and air filter field, and particularly relates to a testable armored vehicle air filter. The testable armored vehicle air filter comprises a primary filter, a secondary filter, a dust exhaust device and a gas collection tank. An assembly structure can be obtained after an engineering design scheme is adopted according to the spatial position and structure features of the testable armored vehicle air filter. Based on the above, flow field simulating calculation is performed on the air filter, and then pressure and flow speed distribution characteristics ofthe air filter can be obtained, and furthermore test points are set according to a simulating result. By carrying out a research for the testable armored vehicle air filter, figuring out laws of internal and external pressure distribution, temperature distribution and flow variation of an air intake system, and reasonably matching filtering elements different in performance, integrated design forthe air intake system is achieved. On the premise of guaranteeing that test components do not influence normal use of the air filter, monitoring for the internal and external pressure distribution, the temperature distribution and the flow variation of the air intake system is achieved.

Description

technical field [0001] The invention belongs to the field of machinery and air filtration, and in particular relates to a testable air filter for armored vehicles. Background technique [0002] The air intake system of an armored vehicle is a comprehensive filtration system, which is composed of a primary filter, a secondary filter, and a dust extraction device. Its function is to filter the dusty air at the front end of the engine intake to ensure reliable work. Nowadays, there is no air filter for armored vehicles that can be tested online, and the obtained flow field data is basically obtained by simulation or laboratory test. This makes the actual application design of the air filter without actual data as a support. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is: how to provide a testable armored vehicle air filter, and realize the pressure distribution inside and outsid...
