In pump chamber, guide vane assembly shroud is peripheral in impeller and is fixed on the pump housing；Pump chamber is provided with column jecket, this stator group
Part is fixed between the inwall of the pump housing and the upper end of column jecket, forms cushion chamber between this column jecket and inwall of pump chamber；
Described impeller has the multiple impeller outlets radially extended along this impeller and enters along axially extended one of this impeller
The mouth of a river, this water inlet connects with column jecket；Guide vane assembly has the multiple stators radially extended along this guide vane assembly
Outlet, one end of this stator outlet connects with impeller outlet, and the other end of stator outlet connects with cushion chamber,
The cavity wall of cushion chamber is provided with pump water out.
Preferably, described guide vane assembly includes multiple stators of the axis axial symmetry distribution with pump shaft, respectively leads
Leaf is fixed on a fixed disk, and the inclined divergent shape of each stator tangent with the edge of fixed disk, adjacent
Formation described stator outlet it is separated by between stator.
Preferably, described impeller includes impeller base and by the multiple blades stretched out on impeller base, and each blade is with pump
The axis axial symmetry distribution of axle, is separated by the described impeller outlet of formation, the external part of each blade between adjacent blades
All being connected with an annular guide wall, annular guide wall surrounds described water inlet.
Preferably, described annular guide wall stretches in column jecket, is set with sealing between annular guide wall and column jecket
Ring.
Compared to existing technology, the beneficial effects of the present invention is:
(1), after the driven by motor pump shaft of the present invention rotates, rotation is drawn water by impeller, and external water stream enters through column jecket
Enter water inlet, impeller outlet enter cushion chamber via stator outlet, owing to current buffer also through cushion chamber
Just export from pump water out after boosting, so current will not pat pump chamber strongly, it is possible to reduce shake and drop
Low noise；
(2) blade of the present invention and stator are all with the axis axial symmetry distribution of pump shaft, therefore impeller outlet and
Stator outlet also forms uniform distribution, so the external water stream of suction is by radially mean allocation from impeller
To cushion chamber, such that it is able to average radial force suffered by pump shaft, impeller, can greatly reduce further pump shaft,
The vibrations of impeller, reduce further noise.
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings.

Detailed description of the invention
Noise reduction damping centrifugal pump as shown in Figure 1, including the pump housing 1, motor 2, pump shaft 3, impeller 4 with lead
Leaf assembly 5, motor 2 is fixed on outside the pump housing 1, and pump shaft 3 support is in the pump housing 1 pump chamber that stretches into the pump housing 1
In 100, impeller 4 be installed on pump shaft 3 and be positioned at the pump housing 1 pump chamber 100 in, guide vane assembly 5 shroud is in leaf
Wheel 4 is peripheral and is fixed on the pump housing 1；Being provided with column jecket 6 in pump chamber 100, this guide vane assembly 5 is fixed on the pump housing 1
Inwall and the upper end of column jecket 6 between, between this column jecket 6 and inwall of pump chamber 100 formed cushion chamber 200；
Impeller 4 has the multiple impeller outlets 41 radially extended along this impeller 4 and along this impeller 4 axially extended one
Individual water inlet 42, this water inlet 42 connects with column jecket 6；Guide vane assembly 5 has along this guide vane assembly 5 radially
The multiple stators outlet 51 extended, one end of this stator outlet 51 connects with impeller outlet 41, and stator exports
The other end of 51 connects with cushion chamber 200, and the cavity wall of cushion chamber 200 is provided with pump water out 11.Wherein,
Motor 2 can be secured in the pump housing 1 upper end by pump bracket.
After motor 2 drives pump shaft 3 to rotate, impeller 4 will be followed rotation and be drawn water, and external water stream enters through column jecket 6
Enter water inlet 42, by impeller outlet 41 via stator outlet 51 entrance cushion chamber 200, owing to current pass through
Cushion chamber 200 just exports after buffering and boosting from pump water out 11, therefore can extract water out with buffering impeller 4
The impact of stream, it is achieved damping noise reduction.
As shown in figs. 2 to 4, the guide vane assembly 5 of this example includes that the axis axial symmetry distribution with pump shaft 3 is many
Individual stator 52, each stator 52 is fixed on a fixed disk 53, and the inclined divergent shape of each stator 52 and with
The edge of fixed disk 53 is tangent, is separated by formation stator outlet 51 between adjacent guide vane 52.
As shown in Fig. 5～6, the impeller 4 of this example includes impeller base 45 and multiple by stretch out on impeller base 45
Blade 43, each blade 43, with the axis axial symmetry distribution of pump shaft 3, is separated by formation leaf between adjacent blades 43
Wheel outlet 41, the external part of each blade 43 is all connected with an annular guide wall 44, and annular guide wall 44 surrounds
Water inlet 42.
Blade 43 and stator 52 all with the axis axial symmetry distribution of pump shaft 3, therefore impeller outlet 41 and leading
Leaf outlet 51 is also formed and is distributed shape uniformly, so the external water stream of suction will be average from impeller 4
Distribute to cushion chamber 200, such that it is able to average radial force suffered by pump shaft 3, impeller 4, can subtract further
Few pump shaft 3, the vibrations of impeller 4, reduce further noise.
Directly entering cushion chamber 200 via column jecket 6 for preventing current leakage, annular guide wall 44 stretches into post
In pipe 6, being set with sealing ring between annular guide wall 44 and column jecket 6, sealing ring can be to leaf each on impeller 4
Sheet 43 seals.
