Halnn Superhard Materials Co.,Ltd
Halnn Superhard Cutting tools has the technology to process the slurry pump and its parts With the high-speed development of Chinese economy. A variety of light and heavy industry rose and developed quickly,slurry pump demand is also increasing, how to manufacture and process an excellent performance in all aspects of slurry pump became the goal of continuing to explore contemporary academia . This article describes the usage and material, and the tools which suit for processing the of slurry pump parts. Part 1 The usage and the material of the slurry pump Slurry pump can also be called centrifugal pump, it is a equipment which use the rolling power of the centrifugal pumps impeller with the help of the is the role of the rotating pump impeller to increase the energy with mixing solid and liquid media, and convert electrical energy into kinetic and potential energy of the medium. As slurry pun works in poor conditions, commonly working in strong acid, alkali or other corrosive substances environment, leading to short life, for obtaining a longer life of slurry pump, we used in high strength and hardness, corrosionresistance and and strong high-chromium alloy cast iron as the main material of the slurry pump, such as Cr15Mo3, Cr15Mo2Cu,KmTBCr12, Cr20, Cr26,etc. The hardness of the High-chromium alloy can reach about HRC60, it is one of the best current performance wear-resistant materials, mainly widely used in mining, electricity, metallurgy, coal, transport and environmental protection industries which abrasive slurry containing solid particles. Slurry pump named differently with its different environment it works, as in the coal washing industry, sea and sand dredging election and other fields, also known as mud pumps, mud pumps, etc. Part 2 Technology to process the slurry pump parts There are many Slurry pump parts, the main components includes impeller, shaft, jacket, front fender, rear fender, pump casing and shaft seal devices. the role of the impeller is transmitting the original motivation of the mechanical energy to the liquid directly, for increasing the static pressure energy and kinetic energy (mainly increase static pressure)of the liquid. The shaft sealing device is used for preventing the liquid in pump housing leaky along the axis or ambient air leaking into the pump housing. The technological process of the Impeller: Rough turn import port ring and front panel----Pure front mouth ring and inner hole(Ensure the concentricity requirement)----Insert keyway (guarantee the keyway symmetry degree)----Drill Impeller balance holes(uniform size distribution)---Test (balance test)--- Checkout. The technological process of the pump shaft: Rough turn----heat treatment (quenching)---- Half finished turning---- finish machining---- external grinding---checkout.
