  The meaning of the model parameters of the air compressor

  General air compressor manufacturers will start with their own company's English alphabet, then fix the volume flow and work pressure behind them. And W generally follows the machine model at the end of the machine as a water cooled air compressor, and F indicates that the air compressor is air-cooled. 1/8 should be followed as well as units, such as 1m /min or 1m /h fand fand per minute or hour after the 8 unit is Kg or MPa, the former is the MPa kg. The kilogram is written as 8Kg, indicating that the MPa is written as 0.8MPa. 1m /min said fand volume flow per minute for fand 1m. 1m /h said fand per hour volume flow is 1m. If you fand the air compressor model is the representation of the type of WF1/8 is obviously not very standardized, or factory number some small brands. Several big brand models for you to see, such as Atlas Atlas, GA55 said Atlas55 kW machine. For example, on behalf of their Ingersoll Rand SSR-55-MM Ingersoll Rand 55KW machine. For example, Japan's Kobelco KOBELCO AG1070A-55 said, Kobelco Japan 55 kW machine. So the English alphabet is a symbol of the name of each company. The number is very simple. 1/8 must be 1 cubic 8 kilograms. As to whether WF is the name of their company, it doesn't make any sense. W or F should be paid attention to in the back of the model, which may be the difference between the air and the water.

  How to calculate how big a air compressor needs

  You can calculate how much gas you use per minute when you use it.

  For example, you every minute 7 cubic gas, the need is greater than 7 cubic meters of air compressor, such as air compressor air compressor power 45KW 7.5m /min fand.

  The calculation of plant consumption volume is required according to your use of pneumatic tools, pneumatic tools, the gas consumption can contact the manufacturer or watch the manual calculation, the sum of consumption volume of all pneumatic tools is the total gas consumption, gas consumption per unit pay attention not to wrong.

  Answer 2: air compressor selection guide work pressure (exhaust pressure) selection when the user to purchase air compressor, we must first determine the gas end the required pressure, plus the 1-2 bar margin, and then select the air compressor pressure (the allowance is considered from the air compressor to the actual installation site gas pressure loss, end line distance according to the distance between bar 1-2 in due consideration of pressure margin). Of course, the size of pipeline and the number of turning points are also the factors that affect the pressure loss. The larger the pipeline diameter and the fewer turning points, the smaller the pressure loss. Otherwise, the greater the pressure loss is.

  Therefore, when the air compressor and the gas pipeline between the end of the distance is too far, should enlarge the competent Road path. If the environmental conditions are in accordance with the installation requirements of the air compressor and the operating conditions permit, it can be installed near the air end.

  The selection of the volume flow in the choice of air compressor volume flow, should first understand the use of all equipment gas volume flow, the flow rate multiplied by the total number of 1.2 (i.e. 20% margin amplification); the new project on the mark according to the design institute to provide the flow of value selection; 3 gas equipment suppliers understand selection the volume of gas equipment flow parameters; the air compressor station can refer to the original parameter value according to the actual situation of gas selection; appropriate selection, is beneficial for the user equipment itself and the air compressor, the selection is too large waste, too small may be caused by the selection of air compressor in long-term loading state or by gas or not enough pressure to fight not to abuse.

  The relationship between the power and the working pressure and volume flow of the three power unchanged, when the speed changes, the volume of flow and pressure is changed accordingly; for example: air compressor of a 22KW, in the manufacture of determining working pressure is 7bar, the calculation speed according to the compressor technology curve, displacement 3.8 m3/min; when the working pressure is 8bar, the speed must be reduced (or motor overload), then the exhaust volume is 3.6 m3/min; because the speed is reduced, the exhaust is reduced, and so on.

  The selection of power is to meet the working pressure and volume flow, and the power supply capacity can meet the power of the matched drive motor.

  Therefore, the steps of selecting the air compressor are to determine the working pressure first, then determine the corresponding volume flow, and finally the power supply capacity.
