Abstract

The utility model discloses a corrugated tube detection device for an intercooler in an engine test, which comprises a bench and an air source. The first pipe joint and the second pipe joint with matching caliber are respectively fixed on the first pipe frame and the second pipe frame; one end of the first pipe joint is connected to the gas source through the pipeline and the air pressure valve, and the other end is used as the corrugated pipe to be tested. The first connection end of the second pipe joint; one end of the second pipe joint is blocked, and the other end is used as the second connection end of the corrugated pipe under test. Four universal rollers are installed on the bottom of the stand. The first pipe joint and the second pipe joint are equipped with clips. After the utility model is ventilated, the air leakage point can be found out and marked for welding repair. The utility model can find out the leakage point of the corrugated pipe for welding repair without going on the stand, which ensures that the broken corrugated pipe of the stand can be replaced in time. The utility model has the advantages of simple structure, convenient use and remarkable economic effect.

Description

Engine test intercooler bellows detection device

technical field

The utility model relates to a bellows detection device for an engine test intercooler, which belongs to the technical field of bellows air leakage detection equipment. the

Background technique

The bellows of the intercooler in the engine test are often damaged, and it is difficult to find the leak point outside the bench when repairing, but it is stipulated that personnel are prohibited from entering the bench when the engine is running; it is difficult to find the leak point. A corrugated pipe is worth 1,600 yuan; frequent breakage causes waste. the

Contents of the invention

The purpose of this utility model is to design a bellows detection device for an engine test intercooler, which can find out the leaks of the bellows and repair them in time without going on a stand. the

Technical scheme of the present utility model: the engine test intercooler bellows detection device of the present utility model comprises a bench and an air source, and two pipe racks are installed on the bench, the first pipe rack and the second pipe rack, two and The first pipe joint and the second pipe joint matching the caliber of the corrugated pipe to be tested are respectively fixed on the first pipe frame and the second pipe frame; one end of the first pipe joint is connected to the air source through a pipeline and a pneumatic valve, and the other end is used as The first connection end of the corrugated pipe under test; one end of the second pipe joint is blocked, and the other end is used as the second connection end of the corrugated pipe under test. the

Four universal rollers are installed on the bottom of the stand. the

The first pipe joint and the second pipe joint are equipped with clips. the

The utility model has the advantages: after the utility model is ventilated, the air leakage point can be found out and marked for welding repair. The utility model can find out the leakage point of the corrugated pipe for welding repair without going on the stand, which ensures that the broken corrugated pipe of the stand can be replaced in time. The utility model has the advantages of simple structure, convenient use and remarkable economic effect. the

Detailed ways

As shown in Figure 1 and Figure 2:

The engine test intercooler bellows detection device of the present utility model comprises a stand 1, and four universal rollers 10 are installed on the bottom of the stand 1. Two pipe racks, a first pipe rack 2 and a second pipe rack 3 are installed on the bench 1 . Two first pipe joints 4 and second pipe joints 5 matching the caliber of the corrugated pipe to be tested are respectively fixed on the first pipe frame 2 and the second pipe frame 3; one end of the first pipe joint 4 passes through the pipeline and the air pressure valve 6 is connected to the air source 7, the other end is the first connecting end of the bellows to be tested, and 8 is the main valve. One end of the second pipe joint 5 is blocked, and the other end is used as the second connection end of the corrugated pipe to be tested. the

The first pipe connection 4 and the second pipe connection 5 are equipped with clips 11 , 12 . the

Operation of the utility model is as follows:

Connect the two ends of the bellows 9 to be tested to the first pipe joint 4 and the second pipe joint 5 respectively, and fasten them with clamps 11 and 12 . Open the main valve 8, then open the air pressure valve 6, the high-pressure gas flows into the bellows 9, observe the air pressure gauge 6a on the air pressure valve 6, adjust the air pressure valve 6 to meet the detection pressure requirements, observe the bellows 9, find out the leak point, and use the symbol Make a mark with a pen. the

After testing, close the air pressure valve 6 and the main valve 8. Carry out welding repair to bellows 9 leaks. the

Air pressure valve 6 can filter the impurity in the air, adjust the size of intake air. The barometer 6a on it is used for observing the size of air pressure. Two clips 11 and 12 are used to fasten the two ends of the bellows. Four universal rollers 10 can move the stand 1 easily. the
