What Is a Rotary Compressor?
The rotary compressor is a new type of compressor. The motor does not need to convert the rotary motion of the rotor into the reciprocating motion of the piston, but directly drives the rotary piston to perform a rotary motion to complete the compression of the refrigerant vapor.

- The rotary compressor is a new type of compressor. The motor does not need to convert the rotary motion of the rotor into the reciprocating motion of the piston, but directly drives the rotary piston to perform a rotary motion to complete the compression of the refrigerant vapor.
- This type of air compressor is more suitable for small air conditioners, especially in household air conditioners. For example, the rotary air compressors produced by the General Electric Company of the United States and Worp have designed better anti-heating and lubrication devices. It adopts a cooling method in which a part of the refrigerant liquid at the condenser is introduced into the compression chamber with a pipe, so that it is sprayed in the cylinder, thereby improving the cooling effect.
- Its main advantages are: due to the rotary motion of the piston, the compression work is smooth, smooth and balanced. In addition, the rotary air compressor has no clearance volume and no re-expansion gas interference, so it has high compression efficiency, fewer parts, small size, light weight, good balance performance, low noise, complete protection measures and low power consumption. advantage. The disadvantage is that the air compressor has high requirements on material, processing accuracy, heat treatment, assembly process and lubrication system. Because it is sealed by the lubricant in the movement gap, in order to separate the oil from the exhaust, the inside of the casing must be made high pressure. Therefore, motors and air compressors are prone to overheating if no special measures are taken. It cannot be used in large air compressors and low-temperature air compressors. Because it has more obvious advantages than other types of air compressors, it has been widely used. For example, domestic refrigerators such as BCD-180W and Ariston BCD-220W refrigerators all use rotary air compressors. Especially in household air conditioners, the application is more common. From the perspective of development trends, rotary air compressors may become the leading products in the market in the future.
- The rotation speed of the rotary compressor is 2900 rpm, the filling oil is 105 grams, and the starting capacitance is 3-4 microfarads.
