The main components of the scroll compressor are fixed scroll, moving scroll, motor suction port and exhaust port.
The internal structure of the scroll compressor is different from the reciprocating piston and rotary piston compressors. Its motor winding is in the lower part, and the cylinder is in the upper part. The installation angle of the movable scroll and the fixed scroll is 180°, and the working volume of the cylinder is formed between the fixed scroll and the movable scroll. When the two scrolls move relatively, the enclosed space moves and the volume changes. When the space shrinks, the gas is compressed and discharged through the exhaust port
Characteristics of scroll compressor
① The torque change of the scroll compressor is small, the vibration is small, and the noise is low. Since the compression process of the compressor is slower during the operation, and two or three compression processes can be performed at the same time, this makes the machine run smoothly, the vibration is small, and the change of the crankshaft torque is small, and the drive torque of the scroll compressor The change is only 1/10 of the rolling rotor and piston compressors. In addition, because the gas is basically continuous flow, the suction and discharge pressure pulsation is small, so that the ability of the air flow in the nozzle to generate vibration is small.
②The scroll compressor has high efficiency. The suction, compression, and discharge of the scroll compressor are continuous and unidirectional, so the harmful superheat of the suction gas is small. Since there is no expansion process of clearance gas, its gas transmission coefficient is high. At the same time, the pressure difference between two adjacent compression chambers is small, and the gas leakage is small. In addition, all points on the rotating vortex are synchronized with a small radius, the friction speed is small, and the friction loss is also small; there is no suction and exhaust valve, and the flow loss is small, so the efficiency is high.
③ Simple structure, light weight, small size and high reliability. The scroll compressor has a simple structure and small moving parts. Compared with a reciprocating piston compressor, its volume is reduced by 40% and weight by 15%. In addition, the axially adjustable performance provided by the controllable thrust mechanism can avoid liquid impact Losses and damage caused. There is no suction or exhaust valve, and the loss is small, so the operation reliability is high. The disadvantage of the scroll compressor is its high price, which is currently limited to use in high-end refrigerators, which is not conducive to popularization.
