An automobile engine system pipeline airtight performance testing equipment

Abstract

The invention relates to an automobile engine system pipeline airtightness detection device. The device comprises a fixing device, an air inlet device and an airbag device, the air inlet device is fixedly mounted at the upper end of the fixing device; the airbag device is fixedly mounted in the left side of the fixing device; the fixing device comprises a rectangular table, universal wheels, an inverted-L-shaped plate, an electric air cylinder, a pressing column, a fixing frame and a buckle. The air bag device comprises a pool tank, a water inlet pipe, a water pump, a graduated scale, a long pipe, an air bag and a positioning plate; a pipeline is fixed through the fixing device, the fixing device can fix pipelines of different sizes, so that the use efficiency of the equipment is improved,the air inlet device is matched with the air bag device, the air outlets and the air inlets of the pipelines are sealed, and the air tightness between the pipelines is detected and compared.

Description

technical field [0001] The invention relates to the field of automobile molding and processing, in particular to a detection device for the airtight performance of pipelines in automobile engine systems. Background technique [0002] With the development of society, the car has almost become a necessary travel tool for every family. In the composition of the car, the car engine is particularly important. It is the device that provides power for the car, also known as the heart of the car, which determines the car Power, economy, stability and environmental protection, the engine pipeline is like the blood vessel of the car, which plays the role of transportation, and the engine pipeline needs to be tested for air tightness before installation. [0003] In the process of testing the engine pipeline, due to the structural limitations of the pipeline, there are the following problems in the actual operation process: [0004] (1) Traditional engine pipeline inspection equipment...

AI Technical Summary

Problems solved by technology

[0004] (1) Traditional engine pipeline inspection equipment can generally only detect pipelines of one size, and can only detect whether the airtightness of the pipeline is good, and cannot compare the airtightness of pipelines

[0005] (2) The traditional engine pipeline testing equipment generally adopts the bubble method and the smear method. The subsequent use of the pipeline increases the difficulty of pipeline processing
