Leak detection alarm timing apparatus

Abstract

The invention discloses a leak detection alarm timing apparatus comprising a leak detection work bench. A support rack is arranged on the leak detection work bench; and leak detection alarm warning lamps and alarm devices are installed at the support rack. A timer and a control panel are arranged at the top board of the leak detection work bench. The control panel includes a power switch button, a warning light switch button, an alarm switch button, a timer switch button and a time setting button and is connected with the leak detection alarm warning lamps, the alarm devices, and the timer. According to the invention, leak detection time is adjusted based on the client requirement; and the operation is simple and convenient. Leak detection time is set on the control panel; a heat exchanger with full air is placed in a leak detection pool and a leak detection timing switch is pressed synchronously; the leak detection alarm timing apparatus starts to count time, the leak detection worker can observe whether a welding point is leaked or not with concentration; and when time is up, the alarm timing apparatus will send an acousto-optic warning signal and the like simultaneously to warn the leak detection worker that the leak detection time is up.

Description

technical field [0001] The invention specifically relates to a leak detection alarm timing device. Background technique [0002] There is a leak detection process in the whole process of the heat exchanger, and the leak detection process can be divided into two leak detection methods: water detection and helium detection respectively. Helium detection requires high-precision equipment for leak detection, but because the value of helium detection equipment itself is more than one million yuan, and the energy consumption used in leak detection is relatively large, the energy consumption is electricity, high-purity nitrogen, and ordinary nitrogen. , Composed of helium. The overall cost of leak detection is at least 10 times higher than that of water inspection. Therefore, most heat exchanger manufacturers will use the water test method to detect leaks. During the leak detection process of the heat exchanger, there are special requirements for the leak detection time. General...

Problems solved by technology

Generally, the heat exchanger factory will put a big clock next to the leak detection pool. During the leak detection, the employees need to watch the clock while checking whether the solder joints of the heat exchanger are leaking. Watching the clock will distract their attention and cannot concentrate Putting in to check the solder joints caused the leaking heat exchanger to flow out of the factory, which brought unnecessary troubles, and at the same time, the leak detection time was somewhat uncontrollable
