Automotive air conditioning compressor parts

Product name: Scrolls Assy

Mechanical properties

 

Scrolls Assy including scroll plates, bearing Chocks and balance weight.

 

Characteristic

1. Stationary and orbiting scroll plates made by the liquid die forging process, with T6 heat treatment to improve the grain anisotropy, solving the machining deformation problem.

 

2. Reliable in-process control to ensure the quality via high precision linear motor machine center, turning center, constant temperature and humidity workshop and work pieces on-line measuring system.

 

3.Stationary and orbiting scroll plates materials are designed as a friction pair, to keep the higher mechanical strength and good anti-friction and wear resistance.

 

4. Base circle involute with fixed and changing radius design; radial flexible mechanism design to make up for the scrolls wall thickness difference and remove the abnormal load;  axial flexible mechanism design to balance the axial gas, reduce the orbiting scroll plates friction. 

 

Application

Electric scroll compressors for new energy vehicles and buses, fuel vehicles scroll compressors, parking air compressors, low speed electric vehicles and refrigerating transportation trucks air compressors.
