Scroll Compressors: The Heart of Superior Technology and Reliable Efficiency As an advanced type of positive displacement compressor, the scroll compressor operates on the principle of two intermeshing scrolls (one orbiting, one fixed) creating a series of gas pockets. These pockets continuously move towards the center while decreasing in volume, enabling smooth and continuous compression of the gas. This fundamental principle grants it significant technical advantages over traditional compressor types. Core Technical Characteristics
Low Noise and Smooth Operation
Mechanism: The suction and discharge processes are continuous and stable, fundamentally eliminating the severe gas pulsations and component knocking sounds caused by the frequent opening and closing of suction and discharge valves found in piston compressors.
Advantage: Multiple compression chambers work simultaneously, resulting in minimal torque fluctuation. The operating torque is only about one-tenth that of reciprocating compressors. This translates to extremely low mechanical vibration and noise levels, creating a quieter operating environment for equipment and reducing vibrational stress on the system piping.
Exceptional Reliability and Durability
Mechanism: Its mechanical structure is remarkably simple, with far fewer moving parts than piston compressors. The core orbiting and fixed scrolls engage via an precision anti-rotation mechanism, operating without contact and thus without wear.
Advantage: This "non-contact" design prevents wear on the primary friction pairs, significantly extending the compressor's service life. It can withstand more demanding operating conditions, such as minor liquid slugging or system fluctuations, demonstrating exceptionally high reliability.
Low Maintenance Requirements and Long Life Cycle
Mechanism: Due to the simple structure and the absence of wear-prone parts like suction/discharge valves or piston rings, primary mechanical wear is eliminated.
Advantage: Users avoid frequent replacement of vulnerable parts, requiring only routine filter changes and system maintenance. This significantly reduces maintenance costs, downtime, and the total cost of ownership over the entire lifecycle.
High Energy Efficiency
Mechanism: The pressure difference between adjacent compression chambers is small, leading to minimal gas leakage loss and typically achieving a volumetric efficiency exceeding 98%. Simultaneously, the absence of mechanical friction between the scrolls results in high mechanical efficiency.
Advantage: Whether at full or part load, scroll compressors maintain excellent Energy Efficiency Ratios (EER/COP), directly saving users substantial operational electricity costs and meeting the stringent energy conservation and environmental protection requirements of modern industry.
