Advantages of Zigong Xingyu
The pump tungsten carbide bushing made by Zigong Xingyu has the excellent capability of good wear-resistance, superb bending strength, corrosion-resistance, especial keep the high hardness under 1000 degree, and hot-resistance, cannot deform even under 500 degree. The bushing are used 100% raw material and HIP sintering technology, and high accuracy. Good concentricity and verticality greatly improve the lifespan of bushing and save the cost for the companies. Zigong Xingyu has various machines to make the tungsten carbide machines, like OD&ID grinding machines, surface grinding machines, centerless grinding machines and chamfer making machines. And the ID surface finish of some bushings can reach the mirror after many times grinding and polishing.
Application of Tungsten Carbide Bushing
In centrifugal pump and chemical pump, tungsten carbide bushing can reduce the wear of pump shaft, balance the multi-stage pump, and lower the fail sealing which caused by vibration. The advantages of tungsten carbide bushing are higher wear-resistance compared to the stainless bushings can prolong the fix period of pumps and valves; wear-resistance, which is suitable for the media such as hydrochloric acid, sulfuric acid, seawater, etc. In control valve and ball valve, tungsten carbide bushing can avoid the jam fault, as the valve seat support ring, because of tungsten carbide hasn’t adhere wear with the stainless steam and can work well under the temperature from -196℃ to 450℃.
