Description

Technical Field

[0001] The utility model belongs to the technical field of air tightness detection devices, in particular to an air tightness detection device for a magnetic transmission stirrer. Background Art

[0002] The airtightness detection device for the magnetic drive agitator is a device used to detect the sealing performance of the magnetic drive agitator of the reactor. It is usually composed of a pressure sensor, an air pump, an airtightness tester and a control system. The device evaluates the airtightness of the agitator by injecting a certain pressure of gas into the agitator and then monitoring the change in gas pressure. If the airtightness is not good, the pressure will leak, causing the pressure value detected by the pressure sensor to be unstable or decrease. This device can promptly detect the sealing problem of the magnetic drive agitator of the reactor to ensure its normal operation and avoid the impact of gas leakage on the experimental environment or production process.

[0003] The airtightness detection device for magnetic transmission agitators in the prior art can only detect a single model of agitator when detecting the magnetic transmission agitator of a reactor, which limits its scope of application in production practice and increases the complexity and cost of the production line. At the same time, the sealing effect of most detection equipment is not good, resulting in inaccurate detection data, affecting product quality. For this reason, we provide an airtightness detection device for magnetic transmission agitators to solve the above problems. Utility Model Content
