Introduction of single screw air compressor

When the single screw is running, the screw and the star wheel have a speed difference, one-way compression, air is easy to compress, and the speed is low. The twin-screw is co-extrusion, which requires high speed, and the lubrication of water is not enough compared to the oil density, and the compressed air is easy to flow backwards. The lubrication part is water, pure water.

Air contains absolutely no oil, but it contains water. In the field of high gas quality requirements, such as textile, metallurgy, food, chemical industry, petroleum and air separation and other places that need pure oil-free compressed air, oil-free screw compressor can provide high-quality compressed gas to meet various needs, so the application prospect is broad.

When the compressor is working, the air is sucked in through the self-cleaning air filter. Through the automatic cleaning filter, the air enters the first-stage compression after being automatically adjusted by the inlet guide vanes. The gas temperature after the first-stage compression is higher, and then enters the intercooler for cooling (the water goes through the pipe, the air goes outside the pipe, and the water flow of the intercooler is required to be 110 m/h) and then enters the second-stage compression system, in order to prevent the gas in the system from pouring into the compression cavity (to avoid starting under pressure), a hanging full-open check valve is installed in the exhaust pipe of the compressor. The gas discharged from the compressor pushes the check valve into the exhaust muffler. Then enter the primary aftercooler, the secondary aftercooler, and then enter the main exhaust pipe.

oil-free air compressor in the process of operation is not involved in the oil, whether it is oil-free piston machine or oil-free screw machine, they will produce a lot of high temperature in the process of operation, if there is oil air compressor oil participation will take away the high temperature generated in the process of air compressor compression, so as to cool the machinery. Explosion-proof oil-free air compressor manufacturers take you to know more!

Stable and continuous displacement (usually expressed by L/MIN): refers to the number of liters of gas flow per minute under the rated working pressure, and to ensure a continuous and stable gas flow, so the air compressor work stability requirements are very high.

Due to the poor intake and exhaust valves of the previous stage, the backflow will cause the interstage air pressure to drop. The poor secondary intake and exhaust valves will cause the interstage air pressure to increase, and the connecting pipe resistance will be large, and the exhaust temperature will increase abnormally.

treatment measures: repair the air valve or replace the new parts, check and clean the pipeline;

the intermediate stage exhaust gas temperature is abnormally low due to the leakage to the outside of the aircraft before the second stage suction.

Treatment measures: check the leakage position and take measures to stop the leakage;
