[Tubing Tips] Determine the purchase of suitable wear-resistant dust suction pipes according to the conveying medium
   Wear-resistant vacuum tube is mainly used for industrial vacuum cleaners or household vacuum cleaners. The requirements for wear resistance are relatively high. Some people buy vacuum tubes that can be used for one month, and some people buy vacuum tubes that can be used. One year, what's the inside story? The following editor will carefully explain the skills of buying wear-resistant vacuum cleaners for you.
   One, specify the conveying medium, and buy a more suitable vacuum tube
  Why do you want to specify the conveying medium? Because the dust suction pipes for dust and particles have different requirements for abrasion resistance. The friction of dust on the pipe wall is relatively smaller, so a thinner suction hose can be used, while the friction of particles on the pipe wall is larger, and a thicker suction pipe must be used. More often, the thickness of the tube wall directly affects the wear resistance and service life of the dust suction tube.

   2. Determine the thickness of the wear-resistant dust suction tube according to the conveying medium
   When the conveying medium is clarified, the thickness of the wear-resistant dust suction tube can be determined. For example, a relatively thinner tube can be used to convey the powder. The two thickness tubes like 0.4mm and 0.6mm are generally used for powder suction. Woodworking machinery is mostly used in related industries. Woodworking vacuum pipes generally absorb wood powder, so lighter and thinner pipes are used. For conveying some solid particle materials, sand and stone, ceramic machinery cutting materials, etc., a 0.9mm wall thickness wear-resistant dust suction tube is required.
   Three. Determine the production material of the vacuum hose according to the ambient temperature of use
   If you use it in the north, or use it in winter, you may encounter problems such as hardening and brittleness of the vacuum tube. This is because the vacuum tube used does not meet the requirements for low temperature resistance. Some customers may use PVC dust suction pipe in order to save costs. However, PVC can only be used at -5 degrees to 65 degrees. Once it is below 0 degrees, the pipe will become hard and brittle. Of course, it is relatively wear-resistant. , PVC is far from the level of pu material, so for the wear-resistant vacuum tube, most of the material used is pu material, and generally there are more steel hoses. The wear resistance of the pu vacuum tube is three to five times that of the PVC vacuum tube, and the temperature resistance is -40 to 125 degrees, and it will not become hard or brittle at minus 40 degrees, like some industrial vacuum cleaner hoses and woodworking suction pipes. The dust pipe is mostly pu steel wire hose.
   Four. Give an example to illustrate how to choose a suitable wear-resistant vacuum hose:
  1. The ventilation and dust removal hose selected for woodworking machinery, furniture, and woodworking engraving machines usually adopts a thin tube wall thickness. Due to frequent swings, the 0.6mm wall thickness PU steel wire telescopic tube is usually selected for woodworking dust collection hose.
  2. PCB drilling machines usually use PU steel wire suction hoses with a wall thickness of 0.9mm. Most of the original drilling machine suction hoses use this type.
  3. Printing machinery ventilation and dust collection pipes generally use a 1.5mm thick wear-resistant steel wire hose. Since the printing machinery has a relatively large wind pressure during ventilation, a thicker pipe wall must be used, otherwise the pressure can reach Not required.
