What are the simple methods for measuring gas volume? How to operate and calculate.
As the air volume of the air compressor is generally measured by using ASME nozzle measuring device to measure the flow of the compressor, as shown in the following figure:
However, as the field conditions cannot meet the test requirements, the more direct method is to use the tank filling method to roughly measure the exhaust volume. The specific methods are as follows:
1) Ensure that there is no long pipeline or other equipment pipeline affecting the volume from the air compressor to the air storage tank. If so, the volume shall be included.
2) There is no air leakage between the air compressor and the air storage tank. The air storage tank has a closed valve to hold the pressure and ensure that the valve does not leak. The pressure gauge on the air reservoir is good.
3) It is suggested that the adjustment of air compressor capacity adjustment fails to prevent the capacity adjustment from affecting the measured value during the test.
4) The frequency conversion or belt conveyor shall ensure that there shall be no speed drop caused by frequency conversion or belt slip under the rated speed of the head during the test.
5) The initial pressure is recommended to be above the opening pressure of the pressure maintenance valve, so as to prevent the calculation from being affected by the non opening of the pressure maintenance valve and avoid the influence on the gas calculation during the start-up loading process.
6) After the above conditions are met, close the exhaust ball valve of the air storage tank, start the air compressor and hold the stopwatch. For example, the opening pressure of the machine pressure maintenance valve is 4kgf and the rated pressure is 10kgf. We'd better calculate the time consumed by the air storage tank from P1 = 4.5kgf to P2 = 9.5kgf, t = 0.5 (min), and the volume of the air storage tank is v = 2m ³， Then the formula of air compressor exhaust volume is q = V (p2-p1-1) / T = 2 × (9.5-4.5-1)/0.5=16m ³/ min。 The above formula ignores the influence of temperature. If the gas temperature difference before and after tank filling is very large, the temperature should be taken into account in the calculation.
