Design And Research Of Detachable Pipeline Pump

Pipeline pump is a kind of widely used centrifugal pump products,mainly used in urban water supply and heating engineering.The index of lift and efficiency is the most important of pipe pump.With the more and more stringent energy saving and emission reduction requirements,the domestic pipeline pump products are still inadequate in performance.With the chance of developing new product of pipeline pump,the product is completely redesigned.The main contents of this paper are as follows:?1?Analyze the market situation of pipeline pump and the development and research of pipeline pump in the world are summarized and elaborated.Determine the performance parameters of new product.?2?Based on many years of practical experience,hydraulic design of pipeline pump's overflowing parts is mainly carried out by using velocity coefficient method,including impeller,water absorption chamber and water pressure chamber.?3?The Catia is used to model the hydraulic components of the primary design of the pipe pump,so as to prepare for the further improvement of the design.?4?By the advanced numerical simulation software of the advanced centrifugal pump,the hydraulic design of the pipe pump is further optimized.The influence of the impeller outlet width b₂ and the blade warp angle?on the performance of the pipe pump is mainly studied.The increase of outlet width helps to improve the lift of pipeline pump,and select the best blade warp angle to help get the best efficiency of the pipeline pump,and finally determine the outlet width of the pump impeller b₂=48mm,?=100.?5?According to the relevant regulations of API610-2010,we design the detachable pipeline pump,and carry out the overall plan design,the main parts'structure design,material selection and the strength calculation of the main parts.?6?According to the design content,the prototype is developed and tested according to national standard.The test results show that the newly designed products fully get the design requirements.
