Brief Introduction of Carbide Nozzle with Water Cutting Tools
1)Outer diameter is usually taken as 6.35mm and 7.14mm
2)Length is 76mm normally,but also has 50mm and 101.6mm dimensions,as the lenght influence the inflow of water and sands mixtures,as well as its assembly and diffusion.
3)Inner hole is normal as 0.76mm and 1.02mm,depending on the cutting precision requirement.Furthermore,have to consider other factors coordination,such as the carbide nozzle's inner holes's size,pressure situation with the equipment,coarse or fine of the sands as well.
Installation steps for the sand tubes
In order to make the sand blending tubes work,please pay attention to the following points.
1)Make the working area with the carbide nozzle seat and fixing sloove of the sand tube clean.
2)To fix the carbide nozzle first,so as to test the water straighness,and then assemble the sand blending tube.
3)Test with the low-pressure water unitl it sprays water straight,no scattering,don't increase pressure to do the cutting work unitl verifying absolute concentricity between the blending tube and carbide nozzle.
4)Turn the sand tube 120 degree every 10~20 working hours.
The above tips are available to keep the sand tube service life at most.
