High Efficiency Submersible Sewage Pump

High Head Large Capacity Centrifugal Vertical Cast Iron Submersible Sewage Pump Usage: farm irrigation, mining and so on.

Overview QZ series submersible axial flow pump is a new generation of submersible axial flow pump products independently developed by our company,it is not only simple in structure,easy to disassemble and assemble,but also has excellent performance as an alternative to traditional axial flow pump. This QZ series of products has a wide spectrum,good hydraulic performance and novel structure.it is characterized by high efficiency,good cavitation performance,easy installation and maintenance,at the same time,combined with the latest information control technology,the intelligent water pump system independently developed can be configured,with automatic monitoring function. The design,manufacture,and quality of this series product meet the standard of GB/T13008 Technical conditions for mixed-flow pump and axial-flow pump JB/T Large and medium-sized submersible motor-pumps Application This series of products can be used for clear water or other liquids with physical and chemical properties close to water whose temperature of conveying medium is no more than 43. They are widely used in municipal engineering, large-scale water conservancy projects, farmland irrigation,industrial conveying water.The thermal power station car-ries 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 Rated voltage:380V or 660V 3KV 6KV 10KV,etc Medium temperature: 43 Starting mode : soft start or frequency conversion Direction of rotation:from the drive end,the pump is rotated in clockwise Product features 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
