Electric Vertical Axial Flow Water Pump For Urban Water Supply
New Products From This Supplier
Application
This series of products can be used for clean water or other liquids with physical and chemical properties close to water whose temperature of conveying medium is no more than 50℃.They are widely used in large-scale water conservancy projects, farmland irrigation,industrial conveying water,The thermal power station carries circulating water, shipyard level,urban water supply and drainage and water diversion projects
Working condition
◆ The medium:clear water,rain water,river water,sewage waste water,any of various liquids whose physicochemical properties resemble those of water
◆ Medium temperature: ≤50℃
◆ Running mode: power frequency or frequency conversion
◆Direction of rotation:from the drive end,the pump is rotated in clockwise
◆Installation:vertical single foundation,vertical double foundation
Structure advantages
1. Guide bearding
◆Standard with high quality rubber guide bearings with small friction coefficient, vibration absorption and especially suitable for axial flow pump
◆The lower guide bearing adopts lengthened structure with better length-diameter ratio, which greatly improves the stability of rotor parts;
◆Designed with enough lubricating flume,and good cooling lubrication effect
2. Outlet bending tube
◆Precision casting,reasonable radius of curvature,internal passage smooth transition,performance optimization
◆The design of the multi-rib structure increases the strength and the rigidity of the body
◆Reasonable hoisting hole design,convenient hoisting
3. Impeller chamber
◆ Precision casting,internal passage smooth transition,performance optimization
◆Half structure for easy maintenance
4. Thrust bearding unit
◆Under conventional working condition,the heat radiation rib of the outer circle radiates heat,so that the external water receiving difficulty in the field is solved
◆Under special working conditions,increase the heat radiation of the coil to ensure that the unit runs for a long time
◆Equipped with on-line vibration measurement and temperature measurement device to ensure safe running
5. Principal shaft
◆Standard steel for high strength shaft,high strength,good rigidity,high critical speed,ensure reliable operation
◆And the part matched with guide bearing and packing is provided with removable protective sleeve, with convenient maintenance
6. Impeller
◆The 3-D flow theory design and CFD computational simulation are adopted,with high efficiency and wide high-efficiency zone,and good cavitation performance
◆Independently developed hydraulic model,high efficiency area is wide
◆Adopt metal mould,precision casting
Product advantages
High-efficiency energy saving: the hydraulic model is designed by 3-D flow theory and calculated by CFD computational simulation,with the best performance in theory. Hydraulic components are made of metal mold,cast precisely guide blade mould is machined by CNC;guide blade shell and suction cone blank are cast by resin sand,solid flow channel is completely in accordance with design drawings,with efficiency higher, and wide high efficiency zone
High reliability:the design of the inlet flow channel is reasonable, the inlet water is uniform without vortex, with smooth running, the absolute concentricity o the pump shaft, and the excellent static balance of the rotor parts ensure that the pump has low vibration and low noise when running at high speed
Advanced technology:all parts using metal mold,precision casting,parts quality is reliable
Low maintenance: reasonable structure,convenient assembly and disassembly, and simple maintenance
Inventory management: reasonable inventory management,short lead time,fast delivery
Automatic monitoring: Equipped with intelligent water pump system independently developed,with automatic monitoring function

LEO Group Pump (Hunan) Co.Ltd. founded in 2000, it is a wholly-owned subsidiary established and invested by LEO Group Co., Ltd. and located in Jiuhua Economic Development Zone of Xiangtan City, Hunan Province. It covers an area of 253.2 Mu and construction area of approx. 92, 635 m2 with total investment of approx. 490 million yuan. It is the most important R&D, manufacturing and testing center of LEO group. The leading products include large mixed flow pump, large mixed axial flow pump (vertical, horizontal, oblique, tubular, submersible etc.), double-suction centrifugal pump, multistage centrifugal pump, slurry pump, desulphurization pump and submerged centrifugal pump. Conventional products are mainly used in mine, metallurgy, coal washing, FGD, municipal water etc. There are numerous high-grade precision and advanced processing equipments, such as 8m CNC vertical lathe and 5-axis linkage machining center, 6m CNC grinding machine and 14m deep well-type thermal treatment furnace. A world-class pump testing center with testing power up to 12, 500 kW realizes high precision tests for real pumps which are used for power station, water conservancy and water resources, petrochemical industry, mining and metallurgical industry. The company is a nationally recognized technology center with strong technology research and development capabilities. It undertakes large-scale water conservancy projects such as the National South-to-North Water Diversion, the Yangtze River to Huaihe River Diversion Project, and the Yellow River Diversion Project, and has newly developed several models for large vertical volute pumps, double-suction centrifugal pumps, multi-stage split pumps, vertical guide vane mixed flow pumps, and axial flow pumps. Some models have been successfully accepted at the China Water Resources Beifang Investigation, Design and Research Co. Ltd. (BIDR) , efficiency reaching the international top level. Following models will be applied in the Pearl River Delta, the second phase of the South-to-North Water Diversion, and the Belt and Road Initiative etc. national key projects. LEO has established a complete product quality management system, from product design and development, manufacturing, parts inspection to after-sales service in full compliance with the requirements of the ISO9001 quality management system, thus ensuring that production and operation activities can be highly efficient and high-quality The operation of each product can serve users efficiently and reliably.
