Scroll air compressor have superior performance and efficiency compared to traditional compressors. Compared with reciprocating compressors of the same capacity, the number of main parts of scroll compressor is about one-tenth of that of reciprocating compressors, and the inspection is reduced by about 40%, the noise can be reduced by 8dB, the efficiency is increased by 10%, the weight is reduced by 15%, and the fluctuation amplitude of the driving torque is only one-tenth of that of reciprocating compressors.
Oil free scroll compressor compress a specific amount of air into compressed air of decreasing volume. They include a fixed scroll (in the housing) and an eccentrically orbiting scroll driven by an electric motor. These vortices form cavitations with gradually changing volumes, which means that the cavitations they form will increase when air enters, and then decrease to produce compressed air. The positioning of the screw gives the scroll main unit radial stability. This process minimizes leakage as the pressure difference in the cavitation is lower than the pressure difference between the inlet and outlet. One compression cycle requires 2.5 turns, which almost guarantees constant and pulsation-free air flow. This is also the reason why scroll oil-free air compressors run relatively quietly.
Since the scroll air compressor works in an open cycle, the working medium is directly obtained from the atmosphere. Once the solid particles mixed in the gas are sucked into the compression chamber, the hard particles are likely to cause abnormal wear of the scroll teeth. The strength design and verification of the scroll disk of the high compression ratio scroll air compressor requires more precision than that of the refrigeration scroll compressor, so it is particularly important to conduct strength verification and friction and wear research on the scroll teeth.
