Abstract
A screw axial flow pump with a novel guide blade is characterized in that end connection between the guide blade (3) and an oil chamber (4) is replaced by side wall connection to enable the oil chamber (4) and a motor (7) to extend into an inner cavity of the guide blade (3). The mounting mode of the guide blade is modified, the oil chamber and the motor extend into the inner cavity of the guide blade instead of directly mounting the oil chamber at the end of the guide blade, and the oil chamber and an inner cavity wall of the guide blade are connected and fixed through screws. The guide blade can be mounted by connecting an outer cavity wall of the guide blade with the outer wall of a suction section through screws. The mounting mode enables the axial length of the pump to be shortened greatly, the pump can be more impact structurally, mounting, operation and maintenance are greatly facilitated, and the effects are more evident especially on larger-sized vertical submersible axial flow pumps.
Description
Technical field
The utility model relates to a kind of main hydraulic part of axial-flow pump, particularly a kind of stator of spiral axial-flow pump.
Background technique
Axial-flow pump belongs to big flow, low-lift pump, is mainly used in agricultural and irritates aspects such as draining, municipal plumbing, power plant's confession circulating water, regional water transfer, and also obtaining application aspect nuclear power, the naval vessel hydraulic jet propulsion this year.At present, general axial-flow pump adopts spatial guide blade mostly, and spatial guide blade is blower inlet casing again; Its main feature is that axial major diameter is to weak point; And axial-flow pump when mounted, generally all the grease chamber is directly installed on the stator, thereby make the axial dimension of axial-flow pump very long; Often make troubles the waste lot of manpower and material resources to installation and operation.
Summary of the invention
For addressing the above problem, the utility model improves the mounting type of stator, no longer the grease chamber is directly installed on the stator end, but the stator inner chamber is goed deep in grease chamber and motor, and the grease chamber is connected through screw with the stator internal chamber wall and fixes.The outer chamber wall of stator links to each other with the outer wall of suction casing through screw, thereby has realized the installation of stator.This kind mounting type makes the axial length of pump shorten dramatically, and makes pump structure compact more, safeguards to installation and operation and has brought convenience, and particularly for the large-scale vertical submersible axial flow pump, effect is more obvious.
Realize that the technological scheme that above-mentioned purpose adopted is:
The used stator of the utility model adopts common mounting type that the axial length of pump is increased because its axial dimension is very long, makes troubles for installation and transportation each side.Therefore, just considered its mounting type during stator, reserved the Conncetion cimension of required thickness, grease chamber and motor of screw joint in advance in design.Adopt stator to be connected and replace its end to connect, make grease chamber and motor stretch into the stator inner chamber, shortened the axial length of pump greatly, make pump structure compact more, install and use and move more convenient with grease chamber's sidewall.
Described spiral axial-flow pump is characterized in that: electromechanical integration, compact structure is diving spiral axial-flow pump.
Described spiral axial-flow pump is characterized in that: stator is a spatial guide blade, adopts the orthodrome transition with the impeller outlet place.
The utility model has the advantages that: make grease chamber and motor stretch into the stator inner chamber, shortened the axial dimension of whole pump, reduced the production and the operation expense of pump.
The beneficial effect of the utility model is: evaded the long stator of axial-flow pump this shortcoming is installed, realized the energy-saving material-saving of whole pump.
The utility model is on probation through the user, and reaction effect is good.
Description of drawings
Fig. 1 is an embodiment's of the utility model spiral axial flow pump structure figure.
Fig. 2 is an embodiment's of the utility model the axial plane figure of stator.
Among Fig. 1: 1. suction casing, 2. impeller, 3. stator, 4. grease chamber, 5. in the hexagonal round head bolt, 6. hexagon head bolt, 7. motor, 8. bearing, 9. mechanical seal, 10. spool, 11. mounting discs, 12. screws.
Among Fig. 2: 13. inlet side, 14. blades, 15. outlet limits, 16. tapped holes, 17. stator inwalls, 18. stator outer walls.
Embodiment
Fig. 1 is spiral axial flow pump structure figure in the present embodiment, and it is mainly by suction casing (1), impeller (2), and stator (3), grease chamber (4), and motor (7), bearing (8), mechanical seal (9) and axle (10) are formed.Fig. 2 is the axial plane figure of spiral axial-flow pump stator in the present embodiment, and it is mainly by blade (14), and stator inwall (17) and stator outer wall (18) are formed.In this example; Take grease chamber (4) to be connected fixing mode through interior hexagonal round head bolt (5) with stator (3) inwall (17); Motor (7) directly is fixed on the top of grease chamber (4) through hexagon head bolt (6); And the outer wall (18) of stator (3) is fastened on the suction casing (1) through screw (12), thereby has realized installing and fixing of grease chamber (4), motor (7) and stator (3).This kind mounting type makes grease chamber (4) and motor (7) stretch into stator (3) inner chamber, thereby the axial dimension of pump is shortened dramatically.
Be specifying that embodiment did with Fig. 1 more than, but the utility model is not limited to the foregoing description, also comprises other embodiments or variation in the utility model concept for the utility model.
Claims (3)
1. spiral axial-flow pump that adopts novel guiding blade is characterized in that: stator (3) adopts sidewall to be connected with grease chamber (4) to replace its end to connect, make grease chamber (4) and motor (7) stretch into stator (3) inner chamber.
2. spiral axial-flow pump according to claim 1 is characterized in that: electromechanical integration, compact structure is diving spiral axial-flow pump.
3. spiral axial-flow pump according to claim 2 is characterized in that: stator is a spatial guide blade, adopts the orthodrome transition with the impeller outlet place.
