Water knife sand pipe is also known as abrasive nozzle, it is an important part of high pressure machinery, which means that it can work in high pressure environment, so that the work can be completed smoothly. The internal working conditions of the water knife sand pipe are very bad, because the speed of the work makes the sand pipe broken very badly, so the material of the water knife sand pipe is wearing resistance, so this becomes the key to the making of the water knife sand pipe. In the general enterprise, the best material is used when making the water knife sand pipe, and the mechanical energy can work for a long time. But at present, the use value of the water stop knife sand pipe is still not satisfied.
A water jet sand tube structure
In fact, the structure of the water knife sand tube is very simple. It is not as simple as imagined. It is mainly composed of both ends. It is a cone and a columnar form, because it uses different machines and different uses, so the size is different. Its structural design is mainly based on mechanical design, which can meet the needs of machinery.
Two, water pipe materials
Water jet sand pipe will be high-speed friction at work, so the material is very important. Generally speaking, the water knife sand pipe must have very high strength wear resistance and high strength hardness, so as to ensure the work of water knife sand pipe. It is made mainly of composite tungsten carbide, which is usually very good in the wear resistance of the cemented carbide, and as a compound, the process conditions will affect the wear resistance.
Three, water jet sand tube wear
Water knife sand pipe in the work of wear resistance is divided into different forms of wear resistance, sliding wear, impact wear and so on, different forms of wear resistance to the water knife sand pipe is different, some of the damage is not very big, and some of the damage is very large, so when making the water knife sand pipe, we must select the material, So as not to strengthen the degree of wear.
Four, water jet sand tube life
The life length of the water knife sand pipe is mainly depended on its own making material, and it has a close relationship with its hardness and wear resistance, so the material of the water knife sand pipe is the key.
