The relationship between the gas flow meter of the air compressor and the pressure

Abstract: The information on the relationship between the gas flow meter of the air compressor and the pressure is provided by the excellent manufacturers of flow meters and flow meters. Our Liangbang Instrument Factory often encounters customers who need to measure the gas flow of the air compressor, so what type or style of flowmeter is more suitable? To solve this problem, we must first understand the working principle and flow parameters of the air compressor. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the relationship between the gas flowmeter and the pressure of the air compressor. Our factory often encounters customers who need to measure the gas flow of the air compressor, so what type or style of flowmeter is more appropriate? To solve this problem, we must first understand the working principle and flow parameters of the air compressor. Let's take a detailed description of the three most basic parameters. What is the relationship between air compressor power, working pressure and volume flow? First, let's understand the definitions of the three. First of all, we need to know what is the working pressure of the air compressor? In fact, the working pressure of the air compressor is often called the exhaust pressure by domestic users. It refers to the maximum pressure of the exhaust gas from the air compressor. The commonly used working pressure unit is: bar or Mpa, and the conversion method is: 1 bar = 0.1 Mpa. Many users usually refer to the unit of pressure as Kg, and the conversion method is: 1 bar = 1 Kg. 2. What is the volume flow of the air compressor? The volume flow is often called the exhaust volume or the nameplate flow by domestic users. It refers to the amount of the gas volume discharged by the air compressor per unit time converted to the intake state under the required exhaust pressure. The volume flow unit is: m3/min or L/min. Generally, the commonly used flow unit is: m3/min. The conversion method is: 1m3= 1000L. 3. What is the power of the air compressor? The power of the air compressor refers to the nameplate power of the matching drive motor or diesel engine. The unit of power is: KW or HP. The conversion method is: 1KW≈ 1.333HP. ① In general, the power of the air compressor refers to the nameplate power of the matching drive motor or diesel engine; ② The unit of power is: KW (kilowatt) or HP (horsepower), 1KW≈ 1.333HP. Secondly, let's look at the relationship between the three: under the condition of constant power, when the rotational speed changes, the volume flow and working pressure also change accordingly; for example, a 22KW air compressor is determined at the time of manufacture The working pressure is 7bar, the speed is calculated according to the technical curve of the compressor host, and the displacement is 3.8 m3/min; when the working pressure is determined to be 8bar, the speed must be reduced (otherwise the drive motor will be overloaded). At this time, the displacement is 3.6 m3/min; because, as the RPM decreases, the exhaust also decreases accordingly, and so on. The power selection is that the power supply capacity can meet the use power of the matched drive motor under the conditions of satisfying the working pressure and volume flow. Therefore, the steps for selecting an air compressor are: first determine the working pressure, then determine the corresponding volume flow, and finally the power supply capacity. What is the relationship between the gas flow and pressure in the pipeline? Pipe diameter - timing, flow is proportional to pressure Pressure - timing, pipe diameter is proportional to flow When the flow is constant, pressure is inversely proportional to the pipe diameter. After figuring out the relationship between these parameters, it is easier to choose the correct and suitable gas flow meter Now, we are a manufacturer specializing in the production of float type differential pressure flowmeters, with product structures such as glass rotor flowmeters, metal tube rotameters, tiny metal tube rotameters, purging device flowmeters and so on. This type of flowmeter has the characteristics of high accuracy, relatively low cost, convenient installation and use, and low maintenance cost for gas measurement, and is deeply loved by users. Consult our company, we have a professional technical team for your selection. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'The relationship between the gas flow meter of the air compressor and the pressure'
