How to judge the quality of the Vacuum Cleaner Hose?
Vacuum cleaner hose is an important part of the vacuum cleaner, its main role is to connect the vacuum cleaner nozzle and vacuum cleaner dust bucket, can not look down on the vacuum cleaner hose, the quality of the vacuum cleaner hose to a certain extent affect the use of the vacuum cleaner effect, the current market vacuum cleaner hose more, in the end how to judge the vacuum cleaner hose good or bad?
1, ventilation Rate:
The medium per unit of time (seconds) can pass the distance (meters), the better ventilation rate can reach 30 meters / second.
2, Caliber, Weight and Pressure:
Caliber is the vacuum cleaner hose inner diameter and outer diameter, usually in millimeters (mm), the weight, usually in kilograms per meter, the weight, usually in the number of kilograms per meter, vacuum cleaner hose generally only allowed to operate in a low-pressure environment not higher than 0.05Mpa, special circumstances will need to bear a certain negative pressure, that is, vacuum.
3, Temperature Range:
Common temperature range is 40 degrees C to 120 degrees C, instantaneous temperature of up to 150 degrees C, bending radius: bending radius refers to r in the right image, it is the vacuum cleaner hose can bend but does not damage or shorten the service life of the inner circle (minimum) radius, if the bending radius is less than the value, the vacuum cleaner hose is likely to kink, The common bending radius is 1 times the inner diameter of the hose.
As above is a simple introduction to the vacuum cleaner hose good or bad judgment method, I believe that through the above introduction, we will have a further understanding and understanding of the vacuum cleaner hose.
