Performance comparison between piston compressors and screw compressors: Piston compressors are noisy and difficult to maintain; most of them experience problems during operation, which causes great inconvenience to users. It can also reduce production costs in factories, increase economic benefits, facilitate equipment management, improve the company’s environment, and enhance its image. Replacing existing piston air compressors with high-efficiency and reliable screw compressors to create an advanced and cost-effective air compression station is an inevitable trend for factories as they continue to expand in the future. The basic criteria for selecting an air compressor are cost-effectiveness, reliability, and safety (the two-certification system). Performance comparison: Traditional piston air compressors have poor economic efficiency and reliability in operation. Piston air compressors are a type of machine that is well-known among many users; they were once a product widely accepted by everyone. However, with continuous technological advancements and the emergence of new types of air compressors, the disadvantages of piston air compressors have become increasingly apparent. Compared to screw air compressors: a) Piston air compressors have numerous wear-prone components such as valves, pistons, piston rings, and rod bearings, which results in poor reliability when operating continuously. This not only affects production but also increases the costs associated with maintenance and management. b. Compared to screw air compressors, piston air compressors have lower efficiency; especially when operating continuously for long periods, their economic viability is even worse. Since there are many vulnerable components in the compression chamber of piston air compressors, the wear and damage of these components lead to greater leakage during gas compression, ultimately resulting in a decrease in the compressor’s efficiency. Since there are no vulnerable components in screw compressors that affect the machine’s efficiency, the pair of rotors used for compression does not experience wear due to the characteristics of their structure. Therefore, the economic efficiency of long-term continuous operation is far superior to that of piston air compressors.
