Whether the entire compressed air system can do the best energy efficiency, and select the appropriate compressor capacity is closely related to the basic principles are as follows: 1, be sure to require manufacturers to provide air consumption and pneumatic equipment Air consumption changes as the analysis of air compressor selection volume basis. 2, if seasonal, time difference, or other factors that may affect changes in gas consumption also detailed assessment. 3, looking to do the whole audience to consider, respectively, the estimated amount of wind lists short, medium, long-term investment plans. 4, do not adhere to the air compressor type, form, capacity must be consistent and use the spare parts are interchangeable concepts, changes in the scope of the air consumption is relatively large, the selection of large and small capacity of both the air compressor The system can provide a more resilient strain range, received an unexpected energy savings. 5, if more than 3-5 compressor air compressor systems manufacturers, as long as careful to select the appropriate control mode and peripherals, without regard to large and small-capacity compressor is configured both to Avoid small-capacity compressor may be idle. Businesses or compressed using the characteristics of the various parts of the plant have their own distinct differences, so choose the capacity of the compressor with a considerable degree of complexity, how to choose the right capacity air compressor, a very detailed assessment in advance important. Six, after cooler by the minimum pressure valve out of the air, through to the after cooler. After the cooler is formed integrally with the oil cooler air compressor factory outlets, the same structure, are all board Alice style. The cold air pumped into the cooling fan, after blowing cooler rocker. The temperature of the compressed air after cooling in ambient temperature typically below + 15 ℃. Seven, minimum pressure valve located above the oil and gas poke fine separator outlet at large air compressor manufacturers, opening pressure set at about 0.45MPa, the minimum pressure valve mainly has the following functions: 1. oil barrel after the gas pressure exceeds 0.4MPa party line turn, can reduce the oil flow through the thin separator air flow, in addition to ensuring the well-known outside the oil fine separation of air compressor manufacturers, and to protect the oil fine separation due to the pressure difference is too large to avoid damage. Priority of cycles required to establish the lubricant pressure 2. start, ensure that the machine lubrication. 3. To return function: When Sullair air compressor parts after running down the barrel of oil and gas pressure drops, the compressed air pipes to prevent backflow. Air compressor manufacturers offer Qin Wei Air (certified), Handan air compressor manufacturers to provide the Compressor Co., Ltd., Xianyang Qin Wei. Xianyang Qin Wei Compressor Co.
