For the refrigeration effect and service life of automobile air conditioner, the leakage check of evaporator and condenser (commonly known as “the two devices”) of automobile air conditioner is indispensable. With the improvement of product quality, the requirement of performance index for leakage check is getting higher and higher, and the traditional leakage checking method can no longer satisfy the demand, and helium mass spectrometry leakage checking system, as a leakage checking method of high precision, has become the The helium mass spectrometry leak detection system, as a high precision leak detection method, has become the choice of officer leak detection for air conditioners. Non-standard customized vacuum chamber type helium mass spectrometry leak detection system has been widely used in automobile air conditioning system.
I. Main functions of vacuum chamber type helium mass spectrometry leak detection system
1、Vacuum chamber type can be designed according to the size of customer’s products, which can meet the leak testing function of evaporator and condenser at the same time;
2、Pressure strength and large leakage airtightness test for both products;
3, the two ware products for vacuum and helium filling, vacuum chamber method helium mass spectrometry detection, automatically determine the product leakage rate qualified and unqualified;
4、Automatic recovery and recycling of helium gas upon completion of the test;
5, the system PLC control, touch screen operation, the detection process is fully automatic, professional and convenient.
2.Second, the air conditioning two commonly used detection leakage rate: 1 × 10-6Pa.m3 / S (R134A, 2 grams / year )
Gadro helium mass spectrometry leak detection system
1、Industry non-standard customization: specialized customization according to customer requirements
2、Intelligent detection: touch screen operation, one key start, vacuum, leak detection, helium recovery, SF6/environmental gas filling fully automatic
3、Safety protection: grating protection, built-in safety switch, electrical interlocking, hierarchical password control;
4、Customizable remote module: remote control, remote maintenance
5、Altitude correction: when the demand-side products are used in high-altitude areas, altitude correction can be carried out
6、Intelligent manufacturing system access: can provide port access to enterprise management system or factory intelligent manufacturing system.
