This helium hood lea test system for SF6 switch gears is with rectangular bell vacuum chambers, two chambers can work linkage, the cycle time is 7 min/pc, can filling helium pressure 5bar, detect large workpiece by helium hood.

Test Schematic:

Test Procedures:

• Charge high pressure gas into the product for gross leak test and proof test；

• Evacute the vacuum chamber.

• Vent gas from the product.

• Evacuate the product and charge helium into the product.

• Test the helium signal from the vacuum chamber by the leak detector for fine leak judge.

• Recover helium from the product.

• Vent vacuum chamber.

Technical Parameters:

Internationally renowned brand hardwares:

Except above internationally renowned brand hardwares, hongce also adopts to our own components of independent intellectual property rights, such as gas recovery unit, helium concentration meter, standard leak holes (with third party calinration certificates) and etc.

Helium concentration meter

Standard leak holes

Why need helium leak detection?

1. The sealing performance requirements increased due to industry development, general leak detection method is hard to achieve the high level leak detection.

2. The pursuit of production capacity increased due to enterprise development , helium leak detection can process the high level leak detection to achieve fast production cycle .

3.Helium leak detection can be fully automatic controlled, reliability is high and the product quality is traceability.
