Air compressor crankshaft manufacturers talk to you about what factors should be paid attention to when selecting screw air compressors?
Many customers don’t know how to choose when buying a screw air compressor. Today, I will talk to you about what needs to be paid attention to when choosing an air compressor, mainly in the two directions of working pressure and volume flow. For selection, please read the overview below carefully.
1. Selection of working pressure (exhaust pressure):
When the user is preparing to purchase a screw air compressor, he must first know the working pressure required by the air end, plus a margin of 1-2 bar, and then select the pressure of the air compressor. (The margin is considered from the air compressor The pressure loss from the installation location of the machine to the actual gas end pipeline, according to the length of the distance between 1-2 bar, appropriately consider the pressure margin). Of course, the size of the pipeline diameter and the number of turning points are also factors that affect the pressure loss. The larger the pipeline diameter and the fewer turning points, the smaller the pressure loss; on the contrary, the greater the pressure loss.
2. Selection of volume flow:
① When selecting the volumetric flow rate of an air compressor, you should first understand the volumetric flow rate of the air-consuming equipment to be used, and multiply the total flow rate by 1.2 (that is, enlarge the margin by 20%);
② The new project can be selected according to the flow value provided by the design institute;
③ Learn about the volumetric flow parameters of the gas-consuming equipment from the gas-consuming equipment supplier for selection;
④ The air compressor station can be selected with reference to the original parameter values and the actual gas consumption situation;
Appropriate selection is beneficial to both the user and the air compressor equipment. Excessive selection is wasteful, and too small selection may cause the air compressor to be in a long-term loading state or insufficient air or pressure can not reach the disadvantages. Therefore, when the distance between the air compressor and each gas end pipeline is too far, the diameter of the main pipeline should be appropriately enlarged. If the environmental conditions meet the installation requirements of the air compressor and the working conditions permit, it can be installed near the gas end.
