Air intake system of power system and engineering machinery

Abstract

The invention discloses an air intake system of a power system and engineering machinery. The air intake system of the power system comprises an air filter, a flow guide cover and a radiating cabin, wherein one end of the air filter is connected with an engine air intake pipe, the other end of the air filter is connected with the flow guide cover, and the other end of the flow guide cover is connected with the radiating cabin; the radiating cabin comprises a radiating cabin body, a first cabin partition arranged in the radiating cabin body and a second cabin partition arranged on the outer surface of the radiating cabin body, first air inlets are formed in the first cabin partition, a second air inlet connected with the flow guide cover is formed in the second cabin partition, and the airinlet area of the first air inlets can be adjusted. The air intake system of the power system has the advantages that the problems that the air intake pipe is sucked flat or an engine emits black smoke because the second air inlet is blocked by large impurities and large particles are solved, standard design of a rainproof cap is avoided, and the problem of limited air intake amount of air inletsof existing rainproof caps is solved.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to an intake system of a power system and an engineering machinery. Background technique [0002] The performance of construction machinery mainly depends on the performance of the engine, and the performance of the engine is often related to the quality of the intake air. [0003] figure 1 For the structural representation of the rain cap air intake system in the prior art, please refer to figure 1 , the air intake system of existing engineering machinery generally installs a rainproof cap 2' above the air filter 1' to improve the air intake system's filtration of air. The air intake system using the rainproof cap generally has the following disadvantages: the rainproof cap is generally The standard design parts matched with the air filter, the air intake of the rainproof cap is limited, and the rainproof cap is exposed outside, which is often blocked by...

[0003] figure 1 For the structural representation of the rain cap air intake system in the prior art, please refer to figure 1 , the air intake system of existing engineering machinery generally installs a rainproof cap 2' above the air filter 1' to improve the air intake system's filtration of air. The air intake system using the rainproof cap generally has the following disadvantages: the rainproof cap is generally The standard design parts matched with the air filter, the air intake of the rainproof cap is limited, and the rainproof cap is exposed outside, which is often blocked by large impurities and particles, and needs to be cleaned frequently. If it is not cleaned in time, the engine will fail The air resistance increases, and the intake pipe is sucked flat, which may easily cause black smoke, speed drop and other faults of the engine
