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 50ºC.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.
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.
