Vacuum cleaner performance testing bench (American, European, and national standards)

I. Overview

Vacuum cleaner performance test bench according to GB/T20291.1TheIEC60312，IEC62885Manufacturing according to relevant testing standards such as national and European standards,The testing parameters for the vacuum cleaner performance test bench include the voltage, current, input power, and power factor of the vacuum cleanerInhalation work Rate, speed, flow rate, vacuum degree, and efficiency. The air performance testing platform adopts a one to two dual-mode control andTesting, integrating European standard testing mode and American standard testing mode.（Can be switched between dual modes, with test data not affected by each otherinfluence）According to European standards IEC60312TheIEC62885Vacuum cleaner specialized testing equipment designed and manufactured in accordance with relevant standardsBe prepared. The relevant test data can be obtained through USBExporting test data and testing platforms are widely applicable to various vacuum cleaner manufacturers and inspectorsTesting the air performance of vacuum cleaners by testing institutions.

■ IIInstrument Description

1. Through servo motor control, the air inlet valve is automatically adjusted,PLC Collect the input voltage of the vacuum cleaner during testingData such as current, speed, input power, power factor, frequency, output power, and vacuum degree, as well as relevant test datacan pass throughUSBExport data.

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 adopts17 Inch touch computer display, capable of real-time display of test electrical parameters, maximum/Minimum air volume, vacuum degree, and transmissionInput power, suction power, and efficiency; When the air duct is fully closed, the maximum is/zuiTest parameters such as low vacuum degree and input power, and record them.
