An intelligent bellows airtightness batch detection device and detection method

Abstract

The invention discloses an intelligent air tightness batch detection device for corrugated pipes, and relates to the technical field of air tightness detection equipment for the corrugated pipes. Theintelligent air tightness batch detection device comprises an odd number of detection stations, and further comprises a control system and an alarm mechanism; connecting joints are arranged at the twoends of the detection stations; one end of each detection station is connected to an outlet of an air pump through connecting pipes I; the other end of each detection station is connected to an inletof a pressure measuring mechanism through connecting pipes II; and the two ends of each detection station are connected separately to form a parallel structure. According to the intelligent air tightness batch detection device, the multiple detection stations can be connected into a whole in series according to needs and then are connected to the air pump and the pressure measuring mechanism in series, so that the multiple corrugated pipes can be detected at the same time, if the corrugated pipes are unqualified, the corrugated pipes are changed into three parts which are connected in parallel, the air tightness of the three parts is detected separately, and the unqualified parts are repeatedly detected according to a same method. The invention further discloses a detection method for theintelligent air tightness batch detection device for the corrugated pipes.

Description

technical field [0001] The invention relates to the technical field of bellows airtightness detection equipment, in particular to an intelligent bellows airtightness batch detection device and detection method. Background technique [0002] Stainless steel corrugated pipe is installed in the liquid conveying system as a flexible pressure-resistant pipe fitting to compensate for the mutual displacement of the connecting ends of pipes or machines and equipment, absorb vibration energy, and can play the role of vibration reduction and noise reduction. It has good flexibility and light weight. , corrosion resistance, fatigue resistance, high and low temperature resistance and many other characteristics. However, the use of existing bellows generally requires a component structure with flanges welded at both ends. When in use, the inner cavity of the bellows is filled with a certain pressure of gas or liquid medium, such as gas and other flammable gases. Therefore, its sealing mu...

Problems solved by technology

[0005] 1) Whether there are bubbles needs to be judged manually, so there are cases of misjudgment and misjudgment;

[0006] 2) Water itself has a certain corrosive effect on stainless steel, which affects product quality;

[0007] 3) During the inspection, the sealing of the product requires manual operation, and the cooperation of two people is required. Manually screw the sealing plugs into the pipe joints at both ends, 8 hours a day, the number of inspections is about 500 pieces, and 0.5 cubic meters of water is needed every day. Low, which increases the detection cost;

[0008] 4) After the product is tested, it needs to be dried. The power of the dryer is 10KW. It needs to be dried continuously for 3 hours a day, and the power consumption is 30KWH per day, which increases the production cost and reduces the production efficiency.

[0010] However, it still has relatively serious shortcomings. For example, the operation steps are still cumbersome. It is necessary to first insert the detection core rod into the corrugated tube to be tested, and then connect the two ends of the corrugated tube to be tested to the equipment testing device through the connecting joints. After the completion, it is necessary to disassemble the tested bellows, and then repeat the above process

In this detection method, only one can be detected at a time, and the detection efficiency is low, which still needs to be improved.
