Description

Gas leakage-proof detection equipment for gas storage cylinder

Technical Field

The utility model relates to an auto-parts processing equipment, in particular to gas leak protection check out test set of gas holder on car.

Background

Air reservoirs are well known as gas pressure devices in automotive brake systems. The air cylinder is used for storing air compressed by the air compressor (air pump) and is used for an automobile braking system. The air storage cylinder has four functions of energy storage, filtration, pressure stabilization and temperature reduction, wherein in the aspect of energy storage, the air quantity of a truck is too much, namely the air quantity is too small to be used for separating and combining a whistle and the air quantity is too large to be used for braking, and if the air storage cylinder is not arranged, the air quantity pumped out by the air compressor is not enough; at the moment, air pumped out by the air compressor needs to be stored in the air storage cylinder and used at a critical moment; just like a mountain stream, the mountain stream cannot drive a generator set, but can be pushed after being accumulated in a reservoir; in the aspect of filtration, because the air contains a large amount of dust and water molecules, if the air enters the air path of a vehicle, the parts of the vehicle are easy to damage after a long time, certain hidden trouble is caused to the driving safety, the air pumped by the air compressor stays in the air storage cylinder for a short time, and the water molecules, the dust and the engine oil in the air fall to the lower part of the air storage cylinder because the relative weights of the water molecules, the dust and the engine oil in the air are heavier than the air, so that the air storage cylinder plays a role in filtration; the design of the pressure-stabilizing single-pipe inlet and outlet air has the advantages that when no good air is pumped into a vehicle through the air compressor in the pressure-stabilizing effect, the compressed air flowing into the air passage of the vehicle is extremely unstable due to the up-and-down movement of the piston of the air compressor, the air storage cylinder is similar to a reservoir, the flowing unstable air stays firstly, and then the compressed air after pressure stabilization flows out through the outlet; in the aspect of cooling, the outside air is sucked into the air compressor to be compressed, the volume is reduced, meanwhile, a certain temperature is generated, the relative density is reduced when the temperature is increased, and the volume of the stored air is reduced; the moisture carried in the air is not easy to precipitate due to the temperature; therefore, the air entering the automobile air passage must be cooled firstly, and the cooling process is realized in two parts, one is a spiral pipe, and the other is an air storage cylinder; therefore, the air tightness of the air cylinder directly influences the driving safety, and the air cylinder needs to be subjected to air tightness detection after being processed. However, the existing detection method basically adopts manual submergence detection, the detection method is difficult to adapt to the capacity requirement of enterprises, the detection efficiency is low, and an air tightness detection instrument is also adopted, but the selling price of the air tightness detection instrument is higher, so that the processing cost is undoubtedly increased.
