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

2. Draw the relationship curves between vacuum degree, input power, suction power, efficiency, and air volume based on the data from each test

3. The equipment adopts a 17 inch industrial control computer display, which can display real-time test electrical parameters, maximum/minimum air volume, vacuum degree, input power, suction power, and efficiency; When the air duct is fully closed, test parameters such as maximum/minimum vacuum degree and input power and record them.

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

5. Pressure equalization box: manufactured according to standards

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