high precision automatic helium mass spectrometer leak detection equipment principle and composition

In recent years, helium mass spectrometer leak detector system has been paid more and more attention and widely used. At present, domestic large-scale air conditioner manufacturers all adopt this technology for their own heat exchangers. Vacuum box helium automatic leak detection device is a typical on-line special high-precision automatic helium mass spectrometer leak detection equipment. It can carry out nitrogen leak detection, pre vacuum, helium pressurization, vacuum box helium leak detection, helium recovery and compression storage, so as to realize the recycling of helium.


This device is matched with helium mass spectrometer with high automation in domestic and foreign manufacturing industry. It is mainly suitable for rapid leakage detection of air conditioner, refrigerator and "two components" on the assembly line, and can also be used in the recovery field of other rare and precious gases.


High precision automatic helium mass spectrometer leak detection equipment working principle :


According to the basic principle of helium leak detection, helium is used as a tracer gas, and helium is filled into the workpiece and put into the vacuum box. Then, the leakage of the workpiece can be quickly and accurately judged by the helium leak detector.


High precision automatic helium mass spectrometer leak detection equipment composition:


Vacuum tank helium automatic leak detection device includes: vacuum tank, evacuation pump group, helium mass spectrometer leak detector, pneumatic valve, solenoid valve, stainless steel pipeline, pneumatic pipeline and electronic control system. The whole device adopts an integrated design, sharing a set of pump set and leak detector, with compact structure, beautiful appearance, convenient maintenance and daily maintenance.

Vacuum box: all stainless steel design, all surfaces are sandblasted after processing. The vacuum box door is automatic sliding door mechanism, which can be opened and closed easily. For the workpiece filled with helium in the vacuum box, the vacuum box is evacuated to 10-sopa (absolute pressure) by the evacuation pump group. If there is helium leakage in the workpiece, it can be detected by helium mass spectrometer leak detector, and the vacuum box is kept in the vacuum state to detect whether there is leakage;


Evacuation pump group: it is divided into rough pump group and fine pump group. The whole set of evacuation pump is assembled on a movable base, which is located in the center of vacuum tank system. The vacuum degree in vacuum box is pumped to 5-30pa (absolute pressure) by the evacuation pump group, which provides a good environment for helium leak detection.


Helium mass spectrometer leak detector: the leak detector unit is equipped with helium mass spectrometer leak detector with high degree of automation at home and abroad. It can detect whether the workpiece can leak helium into the vacuum box, so as to determine whether the workpiece is qualified.


Pneumatic pipe and stainless steel pipe: all stainless steel pipe system ensures high reliability and long service life of the whole system. The pneumatic pipeline provides the pneumatic power for the pneumatic components, and the stainless steel pipe is used to connect the vacuum tank, helium mass spectrometer leak detector and evacuation pump into an integrated system.
