Background technology
Pulp pump is a kind of pump body structure being widely used in the conveying of the liquid mediums such as papermaking, starch and sewage disposal, paper
The impeller form of stock pump can use enclosed, semi-open type and full-open type structure as needed；In the impeller of traditional paper pulp pump housing
In hydraulic structure design, often with the flow of liquid, the hub diameter of wheel speed and impeller is related for the inlet diameter of impeller,
And impeller pump case is often divided into eight pump case sections by pulp pump pump shell structure on the basis of the diameter structure of its pump case basic circle
Segmental arc is designed, and forms whirl room；It is located at the beginning of minor air cell's spiral part in traditional impeller pump shell structure design
End, the position that helical wire portion and diffuser are separated become cut water, are 0 section by the section for crossing cut water head, cut water and the
The angle of eight sections is known as cut water laying angle；But the import of the impeller inlet diameter of the pulp pump of traditional design and pump case is straight
Diameter is often identical, and 1.03~1.08 times that the base circle diameter (BCD) of pump case is impeller diameter；So, if the paper pulp pump housing is solid
Under the operating mode of liquid mixed flow, since in the inlet of the pump housing, flow accelerates flowing, and solid ratio is great in water, so fixed
Inertia force is also more than water, so fixed movement velocity can lag behind the movement velocity of flow, is generated to the flow channels of flow
" relative suction " so that the distortion speed of flow improves, and the strong influence service efficiency of pulp pump pump case shortens paper pulp
The service life of the pump housing；So providing a kind of unusual necessity that new structural pulp pump just seems.
Invention content
The goal of the invention of the utility model：
Primarily to provide a kind of new structural pulp pump, making for paper pulp impeller of pump and pump case is not only effectively improved
With efficiency, the relative suction situation that pulp pump flow channels mouth generates under solid-liquid mixed flow regime is effectively avoided, and effectively
The service life for improving pulp pump, effectively reduce the production cost of enterprise, improve the production efficiency of enterprise, improve
The economic benefit of enterprise.
The technical solution of the utility model is：
A kind of novel pulp pump, including pulp pump ontology are provided, the front end of pulp pump ontology is provided with material inlet
And material outlet, it is provided with impeller body between material inlet and material outlet, pump case is additionally provided on pulp pump ontology
Ontology, in impeller body front end, the impeller inlet diameter of setting is greater than pump case inlet diameter 5mm~8mm；The base of pump case ontology
Circular diameter is 1.2~1.5 times of impeller body diameter；The cut water laying angle being arranged on pump case ontology is 35 °~45 °.
In impeller body front end, the impeller inlet diameter of setting is more than pump case inlet diameter 6mm.
The base circle diameter (BCD) of pump case ontology is 1.25 times of impeller body diameter.
The cut water laying angle being arranged on pump housing ontology is 40 °.
The utility model has the beneficial effects that：
The novel pulp pump of the structure setting, not only effectively raises the service efficiency of paper pulp impeller of pump and pump case, has
Effect avoids the relative suction situation that pulp pump flow channels mouth generates under solid-liquid mixed flow regime, and effectively raises
The service life of pulp pump effectively reduces the production cost of enterprise, improves the production efficiency of enterprise, improves enterprise
Economic benefit.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram at the pump case position of the utility model.
In figure；1 is pulp pump ontology；2 be material inlet；3 be material outlet；4 be impeller body；5 be pump case ontology；6
For impeller inlet；7 be pump case import；8 be basic circle；9 be cut water laying angle.
Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.
As shown in Fig. 1~2, a kind of novel pulp pump, including pulp pump ontology 1 are provided, in the front end of pulp pump ontology
It is provided with material inlet 2 and material outlet 3, impeller body 4 is provided between material inlet and material outlet, in pulp pump sheet
Pump case ontology 5 is additionally provided on body, 6 diameter of impeller inlet of setting is greater than 7 diameter 5mm of pump case import in impeller body front end
~8mm；1.2~1.5 times of 8 a diameter of impeller body diameter of basic circle of pump case ontology；The cut water peace being arranged on pump case ontology
It is 35 °~45 ° to put angle 9.
In impeller body front end, the impeller inlet diameter of setting is more than pump case inlet diameter 6mm.
The base circle diameter (BCD) of pump case ontology is 1.25 times of impeller body diameter.
The cut water laying angle being arranged on pump housing ontology is 40 °.
The Novel paper stuff pump body of the structure setting is simple in structure to be applicable in, during producing and processing pulp pump, by paper pulp
The impeller inlet diameter of pump becomes larger, and is larger than the inlet diameter of pump case, so under mixed flow operating mode, impeller impeller of pump
Inlet -duct area increases, and slows down the movement velocity of flow, keeps it same or similar with the solids movement speed under mixed flow operating mode, this
Sample once come effectively avoid pulp pump flow channels mouth generation relative suction situation, be effectively reduced slurry to impeller
Wash away and wear；After slurry enters impeller, because impeller flow rate on axial surface gradually slows down because active cross-section area expands, solid-liquid
The inertia force of particle is more than the inertia force of water, and under the action of turbine centrifugal power, gradually accelerates to lead over flow, go out in impeller
Relative jam is generated at mouthful so that the flow section of flow is opposite to be expanded, so the distortion speed of flow reduces, will not be produced
Mouth blocks；After increasing the cut water laying angle of the base circle diameter (BCD) of pump case and the pump housing in the pump shell structure design of pulp pump, effectively
Avoid under mixed flow operating mode, when solid-liquid particle is moved out with the axis plane velocity higher than flow, quickly touch pump case
Edge line and to the flow channels of section generate transient occlusion phenomenon so that solid-liquid particle slowly connects with pump case edge line
After touch, it can rapidly leave pump case to enter in pipeline, to effectively reduce slurry washing away and wearing to pump case, improve
The service life of pump case；The novel pulp pump of the structure setting not only effectively raises making for paper pulp impeller of pump and pump case
With efficiency, the relative suction situation that pulp pump flow channels mouth generates under solid-liquid mixed flow regime, Er Qieyou are effectively avoided
The service life for improving pulp pump of effect, effectively reduces the production cost of enterprise, improves the production efficiency of enterprise, carry
The economic benefit of Gao Liao enterprises.
