Screw refrigeration compressor is a high-speed compressor, it is the use of two intermeshing screw relative rotational movement to air. Screw compressor can have a single screw and twin screw. Cylinder built twin-screw type with two screws. There are four male called active rotor teeth (also known as male rotor) one, there are six female teeth (also known as the female rotor) is driven rotor on the other. Are helical rotor. Male and female rotors meshed with each other for reverse pump power, the rotor is mounted in bearings at both ends to form a sealed space between it and the cylinder rotor slots, and the intake and exhaust ports provided at both ends of the rotor. In order to reduce exhaust gas temperature and reduce noise, the general cooling of the rotor injection, while allowing between male and female rotors and the cylinder wall sealing. Works twin-screw compressor: (1) Intake Process: When the active rotor (male rotor) driven by rotation of the motor. It meshes with the driven rotor [female rotor) follow as opposed to a clockwise motion [ie, the other counterclockwise). When moved to a position in communication with the suction Day began intake. When the rotor continues to rotate, this time in a sealed space volume increasing screw air compressor manufacturers, gas also continue to enter, when the rotor is rotated to intake trench sealed suction port is complete feed gas process, when the volume reaches a maximum. (2) the compression process: starting from B rotor continues to rotate, the sealing surface of the groove gradually move to point C vent, sealed spatial volume decreases compressor manufacturers build, in the sealed space i.e., the compressed gas refrigerant pressure rises, until the space is compressed until the communication with the exhaust port, the compression step-up process is completed. 1. Displacement: refers to air flow per unit time is. There are two general methods of identification, are rated displacement (no pressure maximum flow) and air traffic case in 4Bar (kg). Its units: m3 / h (cubic meters per hour), L / mim (liters per minute), CFM (cubic feet per minute). Conversion: m3 / h = 1000L / h = 1000 / 60L / min, 1C.FM≈1.7 m3 / h .. 2, pressure: After the compressor compressed air generated by the force. By industry regulations Silent oil free air compressor maximum pressure is 8 Bar (kg) working pressure should be less than or equal to 8 Bar (kg). Its units are: 8 Bar, kgf / cm2, kpa, Mpa, Psi .. Conversion:.. 1Bar≈kgf / cm2 (kg) = 100 kpa = 0.1 Mpa≈14.5 Psi. 3, Power: units W, KW, HP. Conversion: 1 HP = 750W = 0.75KW. 4, the voltage frequency: 220-240 / 110,50 / 60 or DC DC12V \ 24V \ 36V. 5, the motor speed: the unit is RPM (rev / min). 6, tank volume: units liter (L) and US gallons (Gal). Conversion 1Gal≈3.8 L. 7. Other parameters: the decibel dB (A) air compressor manufacturer, weight Kg, size cm.
