1. Refers to the high pressure abrasive water jet machine tool jet exit is used as the abrasive nozzle is mixed withwater.Because of its internal Jet conditions are harsh, the abrasive wear was accelerated after the sand inside the tube is very large, so need to use very wear resisting material.Materials for manufacturing, sand tube structure is very simple,basically consists of two sections, and a cone entrance and columnar exports.Due to the different USES its size slightly difference.

2. The use of ultra-high pressure technology can turn ordinary tap water pressure to 250 ~ 400 mpa pressure, and then through the inner hole diameter to 0.15 ~ 0.35 mm ruby nozzle spray forming speed is about 800 ~1000 m/s high speed jet, commonly known as it is Water arrows, if arrow has the very high energy, can be used to cut soft materials.If we add right amount ground in water arrows Material can be used to cut almost all hard and soft materials.Adjust the water jet pressure and flow, can use its various cleaning objects, such as glue, paint, rust removal, etc., we can also use for high pressure sterilization of ultra-high pressure technology, food preservation, etc Many beneficial to human work.

3. The nozzle and sand tube not to cause the premature wear of pipe, in order to prolong the service life of the sand tube, before use, first with sand tube with water, ensure that the water in the center position.Rotary sand tube will increase to 120 degree of wear and tear.Should pay attention to the following three questions:
(1) the gem (diamond) have tube to the nozzle from the sand.
(2) check whether there is new gems (diamond) nozzle hole.
(3) the room appear mixed sand abrasion.

If there is no on the jet, jet will directly impact the tube wall, led to the decrease of the cutting speed, at the same time, sand tube service life will be dramatically reduced.Normal sand tube wear an from inlet to outlet of centripetal and continuous wave wear trace.
