Compression capacity and efficiency detection method of diaphragm 三公

The compression capacity and efficiency of the diaphragm 三公 are detected as follows：

&别尘蝉辫;&别尘蝉辫;一、Compression capacity detection method

1.Pressure measurement method: a high-precision pressure sensor is installed at the inlet and exhaust port of the 三公 to start the 三公, so that it runs under a stable condition, record the intake pressure and exhaust pressure at different times, by comparing the difference between the intake pressure and exhaust pressure, and the difference of the exhaust pressure. Value, to evaluate the compression capacity of the 三公.

2.Flow measurement method: install a flowmeter on the inlet pipe or exhaust pipe of the 三公 to measure the gas flow through the 三公 within a certain time. At the same time, combined with the measurement results of the intake pressure and exhaust pressure, the actual compression ratio and exhaust volume of the 三公 under different working conditions are calculated, so as to evaluate its compression capacity.

3.Power diagram method: draw the power diagram of the 三公 through the pressure sensor and displacement sensor installed on the 三公 cylinder. The work diagram can directly reflect the pressure change and piston displacement of the 三公 in a working cycle, and then analyze the working process and compression capacity of the 三公.

4.Load test method: by gradually increasing the load of the 三公, observe its operation under different loads, such as the change of exhaust pressure, flow, temperature and other parameters, as well as the vibration and noise of the 三公, and evaluate its compression capacity and stability under different loads.

1.Direct measurement method: to measure the input power and output power of the 三公 respectively, the input power can be measured by measuring the input current and voltage of the motor, using the formula into the calculation, the output power can be measured by measuring the exhaust pressure, flow and other parameters, according to the thermodynamic principle of gas compression calculation, and then calculate the efficiency difference.

2.Indirect measurement method: by measuring some key parameters of the 三公, such as exhaust temperature, intake temperature, pressure ratio, etc., to indirectly calculate the efficiency of the 三公 by using empirical formula or theoretical model.

3.Comparative test method: under the same working condition, compare the diaphragm 三公 to be tested with the standard 三公 with known efficiency or the efficiency level of the 三公 to be evaluated by comparing the performance parameters of the two, such as exhaust pressure, flow rate, power consumption, etc.

4.Energy balance method: conduct the energy balance analysis of the 三公 and its auxiliary system, measure the input electric energy, heat energy and the output compression energy and heat energy during the operation, establish the energy balance equation, analyze the energy loss and utilization, so as to evaluate the efficiency of the 三公.
