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
