Expansion of Air Performance

1. Empty load open circuit parameters: maximum air volume when the air duct is fully open, maximum vacuum, empty load power consumption, empty load suction power

2. Full blockage parameters: maximum static pressure of fully enclosed air outlet, locked rotor input power, locked rotor power factor (required to be measured by American standard F558)

3. Full operating condition characteristic curve: four-dimensional linkage curve of vacuum degree air volume, input power air volume, suction power air volume, efficiency air volume (automatically collected from 15 sets of throttle points, mandatory according to European standard IEC60312)

4. Maximum suction power point locking: peak suction power corresponds to air volume, vacuum, and input power

5. Air resistance/filter bag pressure difference: The pressure difference between the air duct before and after the filter is installed, the pressure difference changes after dust accumulation, and the ventilation resistance of the filter screen

Standard environmental compensation content

1. Real time collection of environmental temperature, humidity, and atmospheric pressure: automatic correction of air density, compensation of air volume/vacuum degree

2. Automatic calculation of air density correction factor: convert the measured air volume into standard atmospheric pressure and 20 ℃ reference operating condition values

Actual cleaning efficiency

1. Multi working condition dust removal rate: hard smooth floor, crevice floor, short/long velvet carpet, wall dust removal efficiency

2. Fiber/thread pick-up rate: carpet hair, fabric debris grabbing ability

3. Rated dust collection capacity: rated full load volume and effective dust collection capacity of dust collection bucket/bag

Special Project on Noise and Energy Efficiency

1. Weighted noise of whole machine A: noise values under rated operating conditions and maximum suction operating conditions

2. Energy efficiency coefficient: comprehensive energy efficiency of suction power/input power, unit power consumption dust collection capacity

Durability attenuation test

1. Short term continuous aging: The whole machine runs continuously for 1-4 hours, and the power and suction attenuation curves are recorded regularly

2. Durability of switch gear switching: Changes in electrical parameters and air performance after repeated start stop of multiple gears

Adapt to multiple categories of cleaning appliances, expand floor scrubbers/robotic vacuum cleaners/commercial vacuum cleaners, IEC62885 full series

1. Wet and dry dual working conditions of floor scrubber: suction flow rate, negative pressure in sewage chamber, power consumption of clean water pump

2. Vacuum cleaning robot air duct: negative pressure of roller brush compartment, air volume of side suction port, air duct loss rate

3. Commercial industrial vacuum cleaners: high flow, high static pressure segmented testing, multi motor parallel power distribution
