Industrial energy saving 75hp two-stage compression air compressor
Adopt two-stage main engine, the unique main engine design, the first compression unit and the second compression unit are integrated in one body, through the gear drive, so that the rotor of each compression unit can obtain the linear speed.
Rotor profile reduces leakage area and improves compression efficiency.
Between the primary and secondary compression Chambers, oil injection cooling is introduced to replace the intercooler, significantly reducing the loss of compressed air, and controlling the dew-point temperature of compressed air, preventing liquid water from entering the secondary host to cause corrosion, and preventing oil emulsification.
Part of axial intake design is introduced in the primary and secondary main engine, which makes full use of the effective length of screw and makes compression efficiency.Reducing radial unbalance force and improving component life;It also significantly reduces the running noise.
