The sand tube is an indispensable part of the waterjet, and its importance must not be emphasized again by Xiaobian. Besides the quality of the sand tube will affect its performance, the installation method is also critical. Let's share the installation method of the water knife sand tube for your reference.
Before installing the sand tube, we must first ensure that the nozzle surface of the gemstone nozzle and the sand jacket of the gemstone are cleaned and there is no dust; when installing, the gem nozzle is firstly installed, and the water column is tested straight, and then the sand tube is installed; After completion, do not forget to use low-pressure sand-free water until the sprayed water column is straight and free of scattering, thus confirming that the sand tube remains concentric with the gem nozzle.
The next step is to add sand and pressurize the normal incision, and it is necessary to rotate it by 120 degrees every 10-20 hours after using the water knife sand tube so that it always maintains a good working condition.
