Description
Technical field
This utility model relates to the angle adjusting mechanism of a kind of axial pump vane blade, particularly to a kind of governor motion being automatically adjusted axial pump vane sheet angle.
Background technology
Axial-flow pump is a kind of important universal machine, is widely used in various occasion industrial, civilian. There is optimum operating condition point when design in axial-flow pump, when the duty deviation optimum operating condition point of axial-flow pump is more, arises that the situations such as backflow, cavitation, cause that axial-flow pump efficiency reduces, blade surface can be caused spot corrosion when cavitation is serious. Therefore, it is necessary to make axial pump vane blade angle to be adjusted, along with the increase and decrease of flow, flowing more flow field can be made by adjusting guide vane angle, improve the generation that efficiency is anti-cavitation in advance.
Existing guide vane angle regulator is not a lot, and automatic mechanism is often more complicated, and cumbersome in manufacturing installing/dismounting maintenance etc., some control method then need manually dismount guide vane and carry out angle adjustment, wastes time and energy very inconvenient.
This utility model patent is intended to by simple mechanism adjustable axle stream pump guide vane angle.
Utility model purpose
This patent is intended to the automatic adjustment being realized axial pump vane sheet angle by simple as far as possible mechanical mechanism.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple mechanical mechanism and realizes being automatically adjusted of axial pump vane sheet angle.
In order to solve above-mentioned technical problem, the angle adjusting mechanism of the axial pump vane blade that this utility model provides, mainly includes support, the first and second straight-tooth gears, spring, the first and second spiral bevel gears, blade base, poke rod, rotation bar, rotates disk.
Described spring need keep compressive state to guarantee the first and second spiral bevel gears good engagement all the time.
The first described straight-tooth gear and the second spiral bevel gear are rigidly connected, and both remain identical peripheral speed.
Described rotation disk and the first spiral bevel gear are rigidly connected, and both remain identical kinestate.
The described bar one end that rotates is enclosed within the boss rotating disk, and the other end is enclosed within support, rotates and drives rotation bar to do reciprocating swing motion when disk moves in a circle.
Described poke rod also does reciprocating swing motion, band moving vane base reciprocating swing within the scope of certain angle under the drive rotating bar, and guide vane is arranged on blade base, the reciprocating swing in certain angular range together along with blade base.

Detailed description of the invention
Referring to Fig. 1 and Fig. 2, the angle adjusting mechanism of a kind of axial pump vane blade is mainly made up of 1. wheel hubs, 2. support, 3. the second straight-tooth gear, 4. spring, 5. pump shaft, 6. the first straight-tooth gear, 7. the second spiral bevel gear, 8. blade base, 9. poke rod, 10. rotation bar, 11. rotation disks, 12. first spiral bevel gears
Second straight-tooth gear 3 and by driven by motor, with the first straight-tooth gear 6 good engagement, the first straight-tooth gear 6 and the second spiral bevel gear 7 are rigidly connected, and keep engaging with the first spiral bevel gear 12 under the thrust of spring 4. The circular motion of motor can drive the first spiral bevel gear 12 to do circular-rotation.
First spiral bevel gear 12 with rotate disk 11 and be rigidly connected and keep identical kinestate, rotate the cylinder boss at disk 11 place of keeping to the side and can stir and rotate bar 10.
Rotating bar 10 one end and be enclosed within the cylinder boss rotating disk 11, other end is enclosed within support 2, and cylinder boss rotates rotation bar 10 can be driven to do reciprocating swing motion along with rotating disk 11.
Rotating bar 10 and have a cylinder boss, poke rod 9 traverse from blade base 8 near extreme position, one end is enclosed within cylinder boss, poke rod 9 can be driven to swing back and forth, and then stir blade base 8 reciprocating swing when rotating bar 10 reciprocally swinging.
Driven by motor the second straight-tooth gear 3 moves in a circle, and by a series of transmissions, blade base 8 is reciprocally swinging in certain angular range, and axial pump vane blade swings along with base, and stator blade angle obtains adjustment.
