Compressed air is the most important power source in the production industry today, and the compressed air system of Screw Air Compressor is very important for the production enterprise.The correct use of screw air compressor purification equipment dryer and filter in the system, can improve the service life of the pneumatic control system, reduce control system failure and fault, has important significance to improve the work efficiency and economic benefit.
So how to choose dryer based on Screw Air compressor ?According to the following two side :
1.Type of screw air compressor
If using oil lubricated screw air compressor, its oil content indicator >15mg/m3 should be equipped with high efficiency and precision filter and select the external heating type micro-heat regeneration dryer.
2.Exhaust temperature and exhaust pressure of screw air compressor
According to the exhaust temperature and exhaust pressure of screw air compressor, the drying device and supporting equipment can be selected.
When the exhaust temperature above 35 ℃, consideration should be given before the drying machine and oil removal filter equipment after cooler, the gas temperature drop to below 35 ℃.When low exhaust pressure is lower than 0.5mpa, no heat regeneration and micro-heat regeneration dryer should be used, and the external heating, residual heat and internal heat regeneration and drying device should be used with large filling volume and deep adsorption.When the exhaust pressure below 0.2 MPa, again after freeze drying machine should be treated with hot regeneration secondary drying device to get to 40 ℃ under good drying effect.
Because of oil-free Screw Air Compressor screw on the compression process, the whole host of lubrication, sealing and cooling by water, as a result, the letter but oil-free air compressor is oil-free compressed in the true sense.
1) unlubricated structure: the whole machine has no oil to participate in, and the lubricant we use is water, so it can provide users with very clean compressed air.Operation and maintenance costs are extremely low (no air compressor oil, oil fine separation core, oil filter).
2) ideal isothermal compression: because the water cooling performance is far higher than that of air compressor oil, we only 40 ℃, the machine running temperature close to the suction temperature, achieve ideal isothermal compression efficiency.
3) real environmental protection products: because there is no lubricating oil, there is no oil pollution, and all the parts are made of anti-rust materials, such as stainless steel, copper alloy, ceramic and carbon fiber, etc.High precision water filter ensures that the water is kept clean.
4) high efficiency: the pure water used by the BEST-F(N) series air compressor has three functions: sealing, cooling, and lubrication, which is 20% higher than the normal dry compressor.
