An intake manifold air tightness water testing device

Abstract

Disclosed is an intake manifold air-tightness water detection device, comprising a water tank (1), a detection seat (2), a sealing assembly (3), and an intake manifold (9). The detection seat (2) is used for sealing and fixing a cylinder cover combination flange face (91) of the intake manifold (9), the sealing assembly (3) is used for sealing and fixing a throttle valve body combination flange face (94) of the intake manifold (9), and the detection seat (2) can be used for filling high-pressure gas into the intake manifold (9) and can automatically overturn to place the intake manifold (9) into water for detection. The device utilizes water buoyancy to automatically immerse the intake manifold (9) in water for a long time for carrying out an air-tightness test, such that a worker's hands are freed up, and it can be conveniently observed whether there is a leakage situation.

Description

technical field [0001] The invention relates to the technical field of intake manifolds, in particular to a water-testing device for air-tightness of intake manifolds. Background technique [0002] The function of the intake manifold is to distribute the air and fuel mixture from the carburetor or throttle body to the intake ports of each cylinder. Due to the low temperature at the intake end, composite materials have become a popular material for the intake manifold. It is light in weight and smooth inside, which can effectively reduce resistance and increase the efficiency of intake air. When the engine is working, the air pressure of the intake manifold fluctuates greatly, which puts forward requirements for the sealing performance of the intake manifold, and requires testing whether the intake manifold leaks; and the general detection method is to put the intake manifold Each opening of the intake manifold is blocked, and then a certain pressure of high-pressure gas is ...

Problems solved by technology

When the engine is working, the air pressure of the intake manifold fluctuates greatly, which puts forward requirements on the sealing performance of the intake manifold, and requires testing whether the intake manifold leaks; and the general detection method is to put the intake manifold Block each opening of the intake manifold, then inject a certain pressure of high-pressure gas into the inner cavity of the intake manifold, and immerse it in water to observe whether there are bubbles; The intake manifold is put into the water and needs to be kept for a period of time, which increases the labor intensity of the workers
