The working process of the twin-screw compressor
The motor drives the main rotor through the coupling, the speed increasing gear or the belt. Since the two rotors mesh with each other, the main rotor directly drives the auxiliary rotor to rotate together. Under the relative negative pressure, the air is sucked in.
Under the action of the tooth peak and the tooth groove, the gas is transported and compressed, and when the rotor meshing surface is turned into communication with the exhaust port of the casing, the compressed gas begins to be discharged.
The working process of the worm compressor: the motor transmits the power to the worm shaft by a coupling or a belt, and the worm drives the star gear to move relatively in the worm groove, the volume of the closed element changes, the gas, the conveying compression, when the design is reached The pressure value is discharged into the oil separator by a symmetrical triangular exhaust port on the left and right sides of the main body casing.
And the Oil circuit of our LGFD rotary screw compressor is the amount of oil in the units is determined in such a way as to extend the oil change intervals (depending on ambient conditions).An oil level sensor is integrated as standard and is read by the controller. All the units in this series have a horizontal oil separation vessel in which the oil is separated from the compressed air highly efficiently at low speeds.
