Structural Feature
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 Feature
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
