Energy Saving Air Cooling Screw Compressor Two Stage Direct Driven Screw Air Compressor

Short Description:

The two-stage compression oil injection screw air compressor has a reasonable equal pressure ratio, ultra-small leakage, and ultra-low noise host design. It combines the first-stage compression rotor and the second-stage compression rotor in one casing, and directly drives them respectively through the front gear, so that each stage of the rotor can obtain the best line speed matching the gas production during operation, and at the same time, the reasonable compression The ratio can effectively reduce the compression leakage. Therefore, the compression efficiency is much higher than that of single-stage compression. Therefore, compared with single-stage compression, two-stage compression is more energy-efficient.

Product Description

The two-stage compression oil injection screw air compressor has a reasonable equal pressure ratio, ultra-small leakage, and ultra-low noise host design. It combines the first-stage compression rotor and the second-stage compression rotor in one casing, and directly drives them respectively through the front gear, so that each stage of the rotor can obtain the best line speed matching the gas production during operation, and at the same time, the reasonable compression The ratio can effectively reduce the compression leakage. Therefore, the compression efficiency is much higher than that of single-stage compression. Therefore, compared with single-stage compression, two-stage compression is more energy-efficient.

With the same power, it can have 12%-18% more displacement than single-compression compressors. Compared with single-stage compression, two-stage compression saves 15% power. The force on the rotor and bearing is small, and the diameter of the rotor is large and the speed is low. , so the operation is more reliable.
