A barrel helium leak detection device

Abstract

The invention discloses a barrel helium leak detection device, comprising a frame, a leak detection cover, a vacuum pump, a helium leak detector, a workbench and a lifting mechanism. The leak detection cover is arranged on the upper end of the front side of the frame and is connected with The vacuum pump and the helium leak detector are connected. The worktable is located directly under the leak detection cover for placing the barrel. The lifting mechanism is arranged on the front side of the frame to drive the worktable to rise and fall. On one side of the worktable There is a conveying frame for conveying the barrel to the worktable, a limit mechanism that can limit the barrel on the worktable is provided on the other side of the worktable, and a limiter mechanism is provided on the worktable that can limit the position The release mechanism is used to separate the mechanism from the barrel. The release mechanism drives the release mechanism to work through the upward movement of the worktable, so that the barrel can be smoothly and accurately extended into the leak detection cover to ensure the normal operation of the equipment. The gas leak detector works for leak detection; the structure is simple and reasonable, and it can be used in industrial production lines.

Description

technical field [0001] The invention relates to the field of barrel helium leak detection equipment, in particular to a barrel helium leak detection device. Background technique [0002] Since many items such as pesticides, chemical solvents and other chemicals must be stored in a sealed environment due to safety and environmental protection requirements, the sealing performance of steel drums used to hold various chemicals is very important, so it is also used for testing. The leak detection device for container tightness puts forward higher requirements in terms of sensitivity and reliability. As a highly sensitive, clean, environmentally friendly and reliable detection method, helium leak detection has been gradually used in steel drum leak detection. Helium is an inert gas, which has the advantages of small molecular weight, light weight, strong diffusivity and penetration, fast and stable response, and has no chemical effect, does not pollute the detected parts, and is...

Problems solved by technology

However, the existing helium leak detection device consumes a lot of helium gas during detection, the response is slow, and the detection cost is too high, so it is difficult to popularize and apply it on a large scale in industrial production lines.
