There are two types of rotary screw air compressors: single-screw air compressors and twin-screw air compressors. A twin-screw air compressor is a machine designed based on the working principle of the rotation of the twin-screw (also called the yin and yang rotor) to make the volume change of the air. It can take in natural air and complete the work through several internal processes. And finally, discharge the compressed air that meets the pressure requirements. YG Machinery has a professional industry screw air compressor for sale.
The invention of the twin-screw air compressor was more than ten years later than the single-screw air compressor. The design of the twin-screw air compressor is more reasonable and advanced. The twin-screw air compressor overcomes the single-screw air compressor shortcomings of unbalanced bearings easily to fragile. YG twin screw air compressor has the advantages of long life, low noise, and more energy saving. After the technology matured in the 1980s, the scope of application of rotary screw air compressors was gradually expanded. If you are looking for reliable screw air compressor manufacturers, YG Machinery will be your best partner.

Air compressor equipment – screw air compressor adopts high-capacity compression components. Its rotor outer circle speed is low and can reach the best oil injection level. Realize the characteristics of high efficiency and high reliability. The latest design of the YG screw air compressor ensures extremely low system temperature and compressed air temperature. At the same time, all components achieve the best cooling effect and the longest service life.
The screw air compressor has the advantages of high stability, high efficiency, low vibration, and low noise.
The coordination of the rotor and the casing are set. Therefore, there is less leakage of air backflow and no excess gap volume, so the compression efficiency is high.
The sprayed lubricating oil has the functions of sealing, cooling, noise reduction, and lubrication.
Compared with piston-type air compressors, rotary screw-type air compressors have fewer wearing parts and a lower failure rate.
The screw compression working curve is smooth. Compared with the piston-type air compressor, the vibration is small and the noise is low.
Cooling methods have a water cooling type and an air cooling type.
Heat dissipation system: Adopting Plate-fin structure and high-quality materials to ensure the pressure resistance of the cooler, high heat dissipation efficiency, and good corrosion resistance.
Air filter: Heavy-duty, multi-stage air inlet filter, dust removal accuracy 1um (98% efficiency). Large working surface, relatively long service life.
Oil/air separator: The new generation of oil-air separators adopts brand-new filter material, with higher efficiency, and the air-oil content is lower than 2ppm.
Intelligent controller: All operations and related data of the air compressor are displayed on the control panel, which is easy, convenient, and accurate.
Exhaust Pressure
The greater the exhaust pressure of an air compressor, the more energy it consumes. The sum of the operating pressure, and pipeline resistance loss. And the pressure drop of the supporting equipment is set as the lower limit of the rated exhaust pressure of the rotary screw air compressor. Under normal circumstances, the diameter of the air pipeline should be selected larger to reduce resistance loss and achieve the purpose of long-term operation and reduce energy consumption. The higher the discharge pressure of the air compressor, the more energy it consumes. Therefore, do not buy a screw air compressor with a higher discharge pressure than you are using.
Displacement
Calculate the actual total air consumption × 1.1-1.2 coefficient, as the selected displacement model. If the displacement of the selected air compressor is too low, it cannot reach the specified value of the air equipment. The selected air compressor has an excessively large displacement, which will result in high energy consumption for load shedding and uneconomical operation of load shedding. At the same time, a large displacement screw air compressor cost is higher.
