原理：

煤矿用自救器外壳气密性测试仪的工作原理基于差压法‌。测试时，仪器会向自救器外壳内充入一定压力的气体，然后测量一定时间内外壳内压力的变化值。通过对比初始压力和最终压力，仪器可以判断出自救器外壳的气密性是否合格‌。

Principle:

The working principle of the air tightness tester for the shell of self rescue devices used in coal mines is based on the differential pressure method. During testing, the instrument will fill a certain pressure of gas into the shell of the self rescue device, and then measure the change in pressure inside and outside the shell for a certain period of time. By comparing the initial pressure and final pressure, the instrument can determine whether the airtightness of the self rescue device casing is qualified.

应用领域：

主要是煤矿行业和消防安全领域‌。

在煤矿行业中，自救器是矿工在紧急情况下保护自身安全的重要装备。煤矿用自救器外壳气密性测试仪能够检测自救器的气密性能，确保自救器在使用时能够有效地阻隔有害气体的侵入，从而提高矿工在紧急情况下的生命安全。

同时，在消防安全领域，化学氧消防自救器是消防员和其他人员在火灾等紧急情况下进行自救的重要工具。化学氧消防自救器外壳气密性测试仪的应用，可以确保自救器的气密性能符合标准，从而在关键时刻发挥其应有的作用，保障人员的生命安全‌。

此外，这类气密性测试仪还可能被应用于其他需要检测产品密封性能的领域，如电子产品、医疗器械等，但其核心应用领域仍集中在煤矿和消防安全方面。

Application Areas:

Mainly in the coal mining industry and fire safety field.

In the coal mining industry, self rescue devices are important equipment for miners to protect their own safety in emergency situations. The airtightness tester for the shell of self rescue devices used in coal mines can detect the airtightness performance of self rescue devices, ensuring that they can effectively block the invasion of harmful gases during use, thereby improving the safety of miners in emergency situations.

Meanwhile, in the field of fire safety, chemical oxygen fire self rescue devices are important tools for firefighters and other personnel to perform self rescue in emergency situations such as fires. The application of the chemical oxygen fire self rescue device shell airtightness tester can ensure that the airtightness performance of the self rescue device meets the standards, thereby playing its due role in critical moments and ensuring the safety of personnel's lives.

In addition, such airtightness testers may also be applied to other fields that require testing the sealing performance of products, such as electronic products, medical devices, etc., but their core application areas are still concentrated in coal mines and fire safety.
