Features of scroll refrigeration compressor
Advantages of scroll refrigeration compressors:
1. There is no reciprocating mechanism, so the structure is simple, small in size, light in weight, few parts (especially few wearing parts), and high reliability;
2. Small torque change, high balance, small vibration, stable operation, easy operation and easy automation;
3. It has high efficiency within the range of its adapted cooling capacity;
4. Low noise.
Disadvantages of scroll refrigeration compressor:
1. The surfaces of the moving parts are mostly curved. The processing and inspection of these curved surfaces are complicated, and some require special equipment, so the manufacturing cost is relatively high.
2. Between the moving parts or between the moving parts and the fixed parts, the sealing is often achieved by maintaining a certain movement gap. The gas passing through the gap will inevitably cause leakage, which limits the difficulty of the rotary compressor to achieve greater compression Compared with, therefore, most rotary compressors are used in air-conditioning conditions.
3. High sealing requirements and complicated sealing structure.
