How To Choose Pu Steel Wire Vacuum Hose?
PU steel wire hose is mainly used for vacuum cleaning of industrial vacuum cleaners or household vacuum cleaners. The requirements for wear resistance are relatively high, so how to choose a suitable vacuum hose? Need to think about the following points:
1. Clear conveying medium
Why is it necessary to clearly convey the medium? Because the dust suction tube and the dust suction tube have different requirements on the degree of wear resistance. The friction of the dust against the pipe wall is relatively smaller, and a thinner suction hose can be used, while the larger friction of the particles on the pipe wall, the thicker suction pipe must be used. More often, the thickness of the pipe wall directly affects the degree of wear resistance and service life of the suction pipe.
2. Determine the thickness of PU steel wire hose according to the conveying medium
When the conveying medium is clearly defined, the thickness of the wear-resistant dust suction tube can be determined. For example: the conveying powder can be relatively thinner, such as 0.4mm and 0.6mm. These two thickness tubes are generally used to suck powder. The woodworking machinery industry generally sucks wood powder, so it will use a lighter and thinner tube.
3. Determine the material of PU steel wire hose according to the use temperature
If you are using it in the north or in winter, you may encounter problems. The vacuum tube becomes hard and brittle. This is because the temperature of the vacuum hose used does not meet the requirements. Some customers may use PVC suction hoses to save costs, but PVC can only be used from -5 degrees to 65 degrees. Once below 0 degrees, the hose will become hard and brittle, and of course it is relatively wear-resistant In general, PVC is far from the PU material, so most of the materials used for wear-resistant vacuum tubes are pu materials, and generally more steel wire hoses. The wear resistance of PU vacuum hoses is more than three to five times that of PVC vacuum hoses, and the temperature resistance is -40 to 125 degrees, and it will not become hard and brittle at minus 40 degrees, like some industrial vacuum cleaner hoses, woodworking The dust suction pipe mostly uses pu steel wire hose.
