Abstract
The present invention relates to a kind of new double suction Turo pump, the inefficiency and impeller for solving traditional Turo pump run unstable problem, pass through the improvement to pump housing inner-cavity structure, the double-entry impeller of pump simultaneously uses deviated splitter vane simultaneously, the double suction eddy flow efficiency of pump is increased, and ensure the usual of vane channel.Impeller rotation makes medium by the effect energy increase of centrifugal force, moved into interlobate medium by the promotion of blade together with impeller, insertion stream is formd because centrifugal force is larger in the medium of impeller outlet near top, medium in the middle part of impeller forms recycle stream, insertion flows through pump chamber outlet outflow, forms certain lift；Solid particle and fiber in medium obtain energy in the presence of recycle stream, so as to reach the purpose of conveying complex dielectrics or impurity containing fluid.The characteristics of pump inherits Turo pump carries out eccentric placement to axle while the characteristics of having double entry pump concurrently, so that stress convergence is balanced during impeller operation, runs more steady.
Description
Technical field
The invention belongs to pump technical field, primarily directed to the inefficiency of traditional Turo pump, rotate unstable, in blade
Fluid it is not smooth the problems such as.By changing the mechanism of Turo pump inner chamber and impeller, so that its efficiency obtains carrying greatly very much
Rise.
Background technology
Double suction Turo pump is used for pumping complex dielectrics or impurity containing fluid, as containing rubbish, chopped fiber material or excrement
Two-phase fluid, but the efficiency of pump is also ensure that simultaneously, pump suction performance is good, with good anti-cavitation performance, can pump gassiness
The higher liquid of rate, can also pump high concentration, and Turo pump has blocking-free performance good compared with other transh pumps, can be by about
The solid particle suitable with pump discharge bore, but there is certain destructive, the axial direction between impeller and the pump housing to the material of conveying
Influence of the gap to pump performance is sensitive not as centrifugal pump, without gap adjustment.Vortex pump impeller is mostly open type radial direction leaf
Wheel, manufacturing process is simple, and impeller channel is easily worked, but the impeller in operating has equilibrium problem, and impeller operation is not steady enough,
Traditional double suction Turo pump needs certain optimization.
The content of the invention
The purpose of the present invention is the traditional Turo pump of optimization, by the improvement to pump housing inner-cavity structure, and simultaneously using double
Phyllidium wheel, changes the blade construction of impeller, and to the balance optimizing of rotary blade, makes the double suction Turo pump than traditional eddy flow pump efficiency
Rate obtains certain raising, operation it is more steady, overall performance is improved.
The present invention is a kind of double suction Turo pump, and its operation principle is effect energy of the medium by centrifugal force when the impeller is rotated
Increase, moved into interlobate medium by the promotion of blade together with impeller, impeller outlet near top medium because from
Mental and physical efforts are larger to form insertion stream, and the medium in the middle part of impeller forms recycle stream, and insertion flows through pump chamber outlet outflow, forms one
Fixed lift.Solid particle and fiber in medium obtain energy in the presence of recycle stream, most without impeller, and
Without in phyllocyst move after discharged through pump discharge so that reach conveying complex dielectrics or impurity containing fluid purpose.The pump is inherited
The characteristics of the characteristics of Turo pump has double entry pump concurrently simultaneously, it uses double-entry impeller, its single suction equivalent to two same diameters
Impeller works simultaneously, can increase in same impeller outer diameter down-off and be twice, and the blade wheel structure is symmetrical, without axial force, axial direction
Operation is more steady.During due to impeller operation, pump housing intracavitary exit water pressure is smaller, so that the force unbalance of impeller, therefore
The present invention carries out eccentric placement to axle, so that the operating convergence balance of impeller.Turo pump be mainly used in solid particle it is larger compared with
In many environment, blockage problem of the solid particle in runner can effectively be prevented using deviated splitter vane.
It is of the invention main by impeller nut, protecgulum, double-entry impeller, the pump housing, secondary intake chamber, filler chamber, bearing body upper bracket,
Double-entry impeller is provided with right axle pressure cap, wearing plate, gland, bearing body, bearing body lower carriage composition, the pump housing, it is double
Phyllidium wheel is connected by main shaft with bearing body, and the Turo pump uses double-entry impeller, its impeller bias placement 8-15mm；The leaf of impeller
Piece uses deviated splitter vane, and short blade is linear leaf c length (2/5-3/5) times, i.e. L1=(2/5-3/5) L2；Impeller blade exists
Width shared by pump housing inner chamber is (1/4-1/3) of width of blade, i.e. b2=(1/4-1/3) b1.
Prior art is contrasted, beneficial effects of the present invention are as follows：Two-fold advantage of the present invention with Turo pump and Turo pump,
Traditional Turo pump inefficiency problem is overcome, the primary characteristic of Turo pump is remained again.Eccentric placement of the invention can be very
Good out-of-balance force of the fluid to impeller when balancing impeller operation；Rational deviated splitter vane collocation design, is also solved solid very well
Blockage problem of the body particle in vane channel.

Embodiment
Referring to the drawings shown in 1, the double suction Turo pump is, installed in underwater operation, to be pacified the water pump by bearing body support frame
(do not provided on figure) on the support (support height can adjust) of platform, so allow to adjust according to actual needs when mounted
Position of the whole Turo pump on underwater platform simultaneously plays a supportive role, and delivery port connects with fixing pipeline, pump is served certain solid
It is set for using.
Referring to the drawings shown in 1, double suction Turo pump is main by impeller nut 1, protecgulum 2, double-entry impeller 3, the pump housing 4, pair water inlet
Propped up under room 5, filler chamber 6, bearing body upper bracket 7, right axle pressure cap 8, wearing plate 9, gland 10, bearing body 11, bearing body
Frame 12 is constituted.The Turo pump uses double-entry impeller, and the submersible motor of the pump drives the high speed of double-entry impeller 3 to rotate by main shaft,
From two major-minor water inlets enter medium by centrifugal force effect energy increase, into interlobate medium by blade promotion with
Impeller 3 is moved together, insertion stream is formd because centrifugal force is larger in the medium of impeller outlet near top, Jie in the middle part of impeller
Matter forms recycle stream, and insertion flows through pump chamber outlet outflow, effect of the impurity formed in certain lift, medium in recycle stream
Lower acquisition energy, the overwhelming majority is without impeller, without being discharged after being moved in phyllocyst through pump discharge.
As shown in Figure 2,3, 4, the impeller bias placement 10mm of double suction Turo pump of the present invention, carrys out at equalization vent fluid to leaf
The out-of-balance force of wheel；The blade of impeller uses deviated splitter vane, and short blade is the leaf length (1/2) times that comes into leaves, and can make impeller
Runner is more unobstructed；Impeller blade is in width shared by pump housing inner chamber is width of blade 1/4, i.e. b2=(1/4) b1.
