The main function: 

1. Through servo motor control, the air inlet valve is automatically adjusted. The PLC collects the input voltage, current, input power, power factor, frequency, output power and vacuum degree of the vacuum cleaner during the test. The relevant test data can be exported through USB. .

2. According to the data of each test, draw the relationship between vacuum degree, input power, suction power, efficiency and air volume

3. The equipment adopts a 17-inch touch computer display, which can display the test electrical parameters in real time, the maximum/minimum air volume, vacuum degree, input power, suction power and efficiency; when the air duct is fully closed, the maximum/minimum vacuum degree, input power and other test parameters are recorded and recorded .

4. Tested data can be stored and output test reports and curves according to user requirements.

5. Pressure equalizing box: manufactured according to the standard

6. Temperature compensation and modification: modify according to the atmospheric pressure density specified in 5.2.8.4 of IEC60312
