The air conditioning compressor extracts the refrigerant from the low-pressure area and sends it to the high-pressure area for cooling and condensation after compression, and dissipates heat into the air through the heat sink, and the refrigerant also changes from gaseous to liquid, and the pressure increases. The compressor of the household air conditioner is small, and the outer diameter is generally a few millimeters to a millimeter, which belongs to the small one. For small compressors for air tightness testing or operational testing, there are many standard products to choose from. For the compressor of commercial large-scale air conditioner, the compressor itself is relatively large, and the corresponding test interface will be large, the diameter will often exceed 20mm, and the interface shape is varied.
Gripseal Gray Hill Quick Seal Fitting Custom Series can solve large diameter sealing challenges.
Grayhill's custom G70 series features a jaw-style design that extends to the protrusion on the outer wall of the workpiece interface during operation and grasps the protrusion to achieve the gripping function. The inner sealing ring can squeeze the outer wall after the joint is tightened, and the outer wall of the large nozzle can be sealed. The inside can be filled with 2-3 sealing rings, and increasing the number of sealing rings can improve the sealing effect during helium detection. This solution has great advantages in working pressure, sealing stability and helium detection tightness.
Large-caliber customization features:
1. The pressure of the sealing ring can reach 50bar
2. The safety lock design can be added, so that the connector can firmly resist the connector sliding sleeve and prevent it from sliding down in the high-voltage resistant occasions during the working process, which greatly improves the safety.
3. A multi-sealing scheme of 2-3 sealing rings can be made internally to improve the leakage stability of helium mass spectrometry detection.
4. The fluoroelastomer sealing ring can adapt to a higher temperature range, up to 140 degrees Celsius.
