Is suitable the domain:

　　Refrigeration: Home use commercial air conditioning, refrigerator, refrigerator's evaporator and complete machine, seal compressor and so on.

　　Automobile: Wheel hub, filter, fuel tank, air conditioning evaporator, radiator, air conditioning pipeline and so on.

　　Electricity: The high-voltage switch, presses the switch, the transformer, the electron tube and so on.

　　Other: The pressure vessel, the fire extinguisher and so on internal medium sufficient pressure needs the gas tight examination the work piece, the use helium mass spectrum vacuum tank or attracts the gun leak detection method, carries on the helium charge and the recycling situation.

　　Structure composition:

　　The preventive maintenance leaks the system, to find time the deaeration greatly systematic, the sufficient helium compression system, the helium recovery processing system, the electricity supervisory system as well as attracts the gun helium mass spectrum leak detector.

　　System characteristic:

　　1. might completely or the part simulation work piece working condition, avoids the negative pressure leak detection failing to report the phenomenon.

　　2. the actuating medium pure security does not have the pollution, does not pollute is examined the work piece, avoids the following clean drying work.

　　3. helium recycle, recycling fast highly effective, guaranteed that the leak detection room the environment background satisfies the helium mass spectrum leak detection work the background to request, to enable the leak detection work to carry on continuously.

　　4. the work piece fixed point leak detection, may the fast accurate judgment vent size and the position.

　　5. defers to the production actual situation design, uses the multi-location coordination as well as the operating time matches the method reasonably, raised the equipment working efficiency and the system use factor.

　　6. adopts the "one-stop" work style online working, completes the sufficient helium, the leak detection and the recycling in the identical leak detection location and so on whole set process, reduced was examined the work piece the transmission number of times and the disassemblage number of times, the structure compact reasonable.

　　7. the system automaticity is high, has the job safety protection, prevents the misoperation, real-time carries on the monitoring diagnosis, maintains conveniently, the use is simple, imports the high quality equipment component guarantee system to be stable and to be durable. Technical specification:

　　1. is examined in the work piece the volume: Random size, usually 1 - 1000 liters.

　　2. cycle time: Is examined according to the work piece the number to determine, usually 2 - 5 minutes.

　　3. leak detection pressure: Determined according to the work piece actual operating mode, usually 8 - 30 kilograms.

　　4. helium returns-ratio: above 98%.

　　5. may examine the scope: 1×10 - 7 Pa. Above M 3/S.
