Comparison between piston air compressors and screw air compressors 2

Thread Content

c. Piston air compressors are reciprocating mechanisms that possess inherent inertial forces, which result in significant vibration and high noise levels during operation. Larger piston air compressors require a specialized mounting foundation for installation. Screw air compressors are rotary machinery with excellent balance; they generate little vibration and low noise. They do not require a foundation, and they also avoid contaminating the working environment. d. Piston air compressors provide air in a reciprocating, intermittent manner, resulting in significant fluctuations in airflow during operation. In contrast, screw compressors operate at high speeds, delivering air smoothly without any fluctuations in flow, which makes them suitable for users with high air volume requirements. e. Piston air compressors basically lack automatic control systems, whereas screw compressors have sophisticated automatic control and protection systems; they are mechatronic products that facilitate equipment maintenance and management, while also minimizing energy consumption. f. Screw air compressors are products with a highly centralized design; they occupy less space. Without the complex piping systems found in piston air compressors, they help to improve the company’s production environment. There are too many different types of models in use, and they are too dispersed; this not only makes equipment management difficult but also increases the number of wear-and-tear parts, thereby inevitably raising the operational costs. At the same time, the dispersed layout further exacerbates pollution of the production environment. Poor air supply quality leads to high fuel consumption. Piston air compressors suffer from wear of the piston rings. Even though there are oil-scraping rings on the pistons in these compressors, a significant amount of lubricating oil still seeps into the cylinder and is discharged along with the gas. This not only reduces the quality of the gas but also increases oil consumption. The inevitable leakage of lubricating oil further increases oil consumption and pollutes the environment. Screw air compressors feature efficient oil-gas separation systems and filtration equipment; they have no wearing parts, offer high-quality air supply, and have very low fuel consumption. It is for these reasons that **the relevant authorities issued a document in 2000, requiring domestic companies to gradually phase out piston air compressors, which have high operating costs and low reliability, in favor of efficient screw compressors – a practice that has already become a reality in developed countries. In light of the above, in order to reduce production costs, increase economic efficiency, facilitate equipment management, improve the company’s environment, and enhance its image, it is an inevitable trend for your company to replace the existing piston air compressors with high-efficiency, reliable screw compressors, and to build an advanced and cost-effective air compression station.
