When preparing to purchase an air compressor, first determine the working pressure required for the gas end, plus a margin of 1-2 bar, and then select the pressure of the air compressor. (The margin is considered from the installation site of the air compressor. (For the pressure loss from the actual gas-side pipeline, the pressure margin should be properly considered between 1-2 bar according to the distance). Of course, the size of the pipe diameter and the number of turning points are also factors that affect the pressure loss. The larger the pipe diameter and the fewer turning points, the smaller the pressure loss; otherwise, the greater the pressure loss.
Therefore, when the distance between the air compressor and each gas-side pipe is too far, the path of the main pipe should be enlarged appropriately. If the environmental conditions meet the installation requirements of the air compressor and the working conditions permit, it can be installed near the air end.
Selection of volume flow:
1. When selecting the volumetric flow rate of an air compressor, you should first understand the volumetric flow rate of all gas-using equipment, and multiply the total flow rate by 1.2 (that is, enlarge the 20% margin);
2.The new project can be selected based on the flow value provided by the design institute;
3.Know the volume flow parameters of the gas equipment from the gas equipment supplier for selection;
4.Air compressor station reconstruction can refer to the original parameter values in combination with actual gas usage for selection;
Appropriate selection is beneficial to both the user and the compressor equipment. Too large selection is too wasteful. Too small selection may cause the compressor to be in a long-term loading state or lack of gas or pressure.
The relationship between power and working pressure and volume flow
Under the condition of constant power, when the rotation speed changes, the volume flow and working pressure also change accordingly; for example: a 22KW air compressor, the working pressure is determined to be 7bar during manufacture, and calculated based on the technical curve of the compressor Rotational speed, the displacement is 3.8 m3 / min; when the working pressure is determined to be 8 bar, the rotational speed must be reduced (otherwise the drive motor will be overloaded), at this time, the displacement is 3.6 m3 / min; because the rotational speed is reduced, the displacement Qi is reduced accordingly, and so on.
The power is selected under the conditions of working pressure and volume flow, and the power supply capacity can meet the used power of the matched drive motor.
Therefore, the steps for selecting an air compressor are: first determine the working pressure, then the corresponding volume flow, and finally the power supply capacity.
Linsheng is one of the professional Air compressor Suppliers in China. Compressed air can also be used in automotive areas to provide power. The car air compressor is suitable for inflating bicycle tires, car tires and sports balls. It inflates ordinary tires in 5 to 6 minutes. This is a built-in pressure gauge with compactness and low power consumption. We have obtained ISO9001-2000 and BSCI certificates. Our products are exported to customers in the United States, Europe, Africa and Asia. We also welcome OEM and ODM orders.
