Screw air compressor is one of the types of pneumatic devices, its main function is to produce compressed air. The main mechanism of the device is a screw pair, which draws in air during rotation in oil. The helical pair consists of two rotors with helical teeth, this design feature is the main difference from other piston devices. This principle of operation reduces friction and wear of compressor elements several times.
The design has been used since 1934, its widespread use was largely determined by such factors as high reliability, metal consumption and small dimensions. The use of a screw air compressor helps to reduce energy consumption by up to 30% of energy, which increases its competitiveness in relation to other types of compressors.
Other advantages of using air compressors include high resource and productivity, low noise and energy consumption, low vibration, ease of installation and maintenance.
The device is designed for continuous operation, does not require the constant presence of personnel. For its installation, it is not necessary to allocate a separate room, the unit can be placed in an ordinary workshop, there are also no requirements for the foundation. The screw compressor, with all its characteristics, is distinguished by its ease of operation, does not require frequent repairs.
This type of equipment is increasingly being installed in ship refrigeration units and mobile compressor stations.
