Tungsten carbide wear plate and wear ring is a pair of close coordination with the relatively moving part, the surface of these two parts coated with wear material, through the end of the spline nut opposite sex in S-shaped tube, concrete pump could adjust their gap between (0.1~0.2)mm. The rubber spring assembly in the middle of S-shaped tube and wear ring, the wear ring and wear plate will be flexible and comfortable on relative movement.
Tungsten Carbide Wear Plate and Wear Ring Affecting Factors
1.The difference between each site of concrete pumping. In general, a reasonable proportion of concrete (such as ready-mixed concrete), wear plate, wear ring's life will be longer. If the site using concrete, wear plate's life up to more than 1.5 Articles, but also the life of the wear ring is also between 0.8 and 1.2 Articles.
2. Each site pumping conditions differences. In height, long distance pumping concrete conditions, tungsten carbide wear plate and wear ring is bear a greater back pressure, so the shorter life expectancy.
3.The gap of tungsten carbide wear plate and wear ring will affect the life. wear ring has a great preload, which can squeeze in glasses plate. When pumping, the pump will not be able to enter the pulp. At this spectacle wear plate occur on the entire plane, wear more evenly, so the longer life expectancy. The wear ring wear occurs on the edges of the wear ring, if we can promptly adjust the direction of the wear ring to wear uniform edge, then wear ring life will be doubled. Since each work cycle will be cut with the wear ring twice, so the tungsten carbide wear plate at the bridge of the nose is the most easily accessible place small aggregates, which can easily cause the nose to wear tungsten carbide wear plate scrapped.
Therefore, concrete pump at work for some time, you should adjust the direction of the wear ring, tighten the nut straight, which will greatly extend the tungsten carbide wear plate and wear ring's life.
Main material for tungsten carbide EDM electrode is copper, iron and tungsten copper alloy, these electrode material with their own characteristics, can be used for different occasions. Copper is the most common for electrode material,which can be manufacture more complex electrode tool under cold extrusion processing. Tungsten copper with the best heat resistance, which is the best material for electrode tools, but it with high costs and highest unit price. In the early iron is widely used as tungsten carbide EDM electrode during the period of thyratron pulse power, and now is continue to use the EDM pulse power transistor for some mold makers. The three electrode materials used in tungsten carbide EDM electrode with the completely different wear characteristics. Find out the processing rules of tungsten carbide EDM electrode, which is able to provide some date under developing special carbide machining pulse power. Also with some practical significance on the development of EDM technology and improving the mold machining accuracy.
