What are the working principles of the vacuum cleaner motor air performance test device?

　　
This equipment plays an important role in the development, production, and quality testing of vacuum cleaners. Let's take a look at how Guangzhou Zhipinhui Electronic Technology explains the working principles of a vacuum cleaner motor air performance tester.

1. Electrical performance parameter input test: High-precision electrical parameter instruments are used.

2. User-provided differential pressure sensor and measuring instrument for vacuum measurement.

3. Pressure equalization chamber: 18" x 18" x 10" high, conforming to the American standards ASTM F558 and F431 orifice plate method.

4. Orifice plate range: One standard orifice plate (0.5" with manual switching), accuracy ±0.05mm.

5. Tested unit: Two types of 32" and 35" hose connectors (or user-specified), or nozzle connectors.

6. Product pass/fail indicator system with audible and visual alarms.

Pass results trigger the cylinder to pop up; failure requires manual operator control of the switch.

7. Operating table height: 700mm (customizable).
