The factors Influence Service Life of Water Cutting Tool's Sanding Tube
1)Having to pay attention to the proportion between carbide nozzle's and sanding tube's inner hole,it is the best one as 1:3,for example,if the sanding tube's inner hole is 1.0mm,so the carbide nozzle's should be 0.33mm,such proportion has been tested by a lot times,it has the strongest cutting strength and the lowest fray on the wall of sanding tube.
2)The sands' size and weight,if they are too coarse and mixed with impurities,resuled in the tube weared quickly.
3)Dirty and hard water without filtration is easy to break the carbide nozzle against high pressure situation,leading to it scatters and damages the tube's inner wall soon.
4)Actually the most important factor is the concentricity between the carbide nozzle and sand tube,as even a very small deviation of the concentricity,the water wont spray straight vertically and wear some part of the tube's inner wall,meanwhile,also make the cutting strength weak with low speed.
