What are the advantages of Semi-Hermettc Screw Refrigeration Compressor in terms of operational stability?

The rotor design of Semi-Hermettc Screw Refrigeration Compressor is the basis for their stable operation. The rotors are supported by rolling bearings. This design makes the gap between the rotors very small, thereby ensuring the stability of the axis. This tight gap not only reduces the leakage loss of gas, but also improves the compression efficiency. In addition, the internal structure design of the compressor has also been carefully optimized to ensure smooth operation under various working conditions. In terms of cooling capacity adjustment, Semi-Hermettc Screw Refrigeration Compressor usually use a mobile slide valve for stepless adjustment. This adjustment method is superior to the step-by-step cooling capacity adjustment of reciprocating compressors because it can more accurately match the actual cooling demand and avoid energy waste or poor cooling effect caused by excessive or insufficient cooling capacity. This precise adjustment capability enables the compressor to maintain a stable operating state under various working conditions.
The lubrication and cooling system of Semi-Hermettc Screw Refrigeration Compressor is also one of the key factors for their stable operation. The compressor usually uses a differential pressure oil supply method, which simplifies the lubrication oil supply system and reduces the failure rate. At the same time, the inhaled gas is first cooled by the motor before entering the cylinder for compression and discharge. This design not only helps to reduce the temperature of the motor and improve operating efficiency, but also ensures that the gas temperature in the cylinder is moderate, which is conducive to the stable operation of the compressor. Some advanced Semi-Hermettc Screw Refrigeration Compressor also use liquid refrigerant injection for cooling. This cooling method can more effectively reduce the temperature of the compressor, especially when operating in a high temperature environment, and can significantly improve the stability and reliability of the compressor.
Modern Semi-Hermettc Screw Refrigeration Compressor are usually equipped with advanced control systems, such as PLC control systems. These control systems can realize the precise start and stop of the compressor, energy regulation, and operating status monitoring of key components. By accurately controlling the operating parameters of the compressor, such as speed, cooling capacity, etc., it can ensure that the compressor can maintain the best operating state under various working conditions. In addition, the advanced control system also has a remote communication function, allowing managers to grasp the operating data of the unit in real time. Once an abnormality or potential problem is found, the manager can immediately take measures to deal with it, thereby avoiding the occurrence of failures and ensuring the stable operation of the unit.
Semi-Hermettc Screw Refrigeration Compressor have a wide range of adaptability and can adapt to different refrigerants, temperatures, pressures and other conditions. This allows it to maintain stable performance in various application scenarios. Whether used in cold storage, air conditioning or other refrigeration equipment, Semi-Hermettc Screw Refrigeration Compressor can provide reliable and stable refrigeration effects.
Since the semi-hermetic screw refrigeration compressor has a reasonable structural design and few wearing parts, it is relatively easy to maintain. This helps to reduce downtime and improve the overall operating efficiency of the equipment. Regular maintenance and care can ensure the long-term stable operation of the compressor and extend its service life.
