Description
Technical field
The utility model relates to a kind of actuating device being applied to variable oar vane pump adjustable angle.
Background technique
The application of vane pump is more and more extensive.Particularly nuclear power plant is to the wilderness demand of seawater, vane pump be tending towards large discharge, heavy caliber, high efficiency and high-power.The operation of unit because of the amount of freezing mixture (as seawater) needed for season difference different.Oar form is fixed in the many employings of existing vane pump, and namely blade angle is non-adjustable, can only, with single flow feeding medium, can not regulate the flow of freezing mixture, and the blade of fixing oar be non-exchange according to calendar variation.
Summary of the invention
The purpose of this utility model be to provide a kind of can by the Angulation changes flow of adjusting vane pump variable oar, and then the actuating device being applied to variable oar vane pump adjustable angle of saving power.The technological scheme that the utility model adopts is: a kind of actuating device being applied to variable oar vane pump adjustable angle, it is characterized in that: hollow main shaft (2) is inner is set with controlling rod (1), controlling rod (1) and hollow main shaft (2) Spielpassung, be fixedly mounted on the crosshead (3) on controlling rod (1), for the setscrew nut (10) of axially locating crosshead (3), setscrew nut (10) mode of being threaded connection is tightened on controlling rod (1), by pin-and-hole orientation type, locating stud (4) is fixed in crosshead (3), spheric connection (5) and crosshead (3) link together by locating stud (4), locating stud (4) is hinged fixing by one end of pin-and-hole and spheric connection (5), spheric connection (5) the other end and parallel pin (6) hinged, parallel pin (6) is fixedly connected with vane arm (7), blade (8) and vane arm (7) are fixed by spline, crosshead (3) is equipped with by dovetail groove and sliding tile (9).
Utility model works principle: the utility model is when the flow of adjusting vane pump, moved by the axial reciprocating being arranged on the inner controlling rod (1) of hollow main shaft (2), the crosshead (3) be fixed on controlling rod (1) by setscrew nut (10) is driven to move up and down, and then the spheric connection (5) driving locating stud (4) to be connected with crosshead (3) moves up and down, spheric connection (5) drives vane arm (7) to rotate around blade rotor by parallel pin (6), blade (8) and vane arm (7) are fixed by spline form, and then blade (8) can rotate with vane arm (7), realize the adjustable of blade (8) angle, constant in circumferencial direction angle for ensureing crosshead (3), solve by adopting to coordinate with the dovetail groove of sliding tile (9), described oat tail groove structure can realize the sliding tile (9) that cooperatively interacts and crosshead (3) to-and-fro motion and not throw off.
Technique effect of the present utility model is: the utility model is based on adjustable blade burner and then realize that pump duty is adjustable to be designed, all systems needing pump duty to change that is in operation all can adopt, due to this device convenient disassembly, each blade all can be changed, and therefore practicability is very strong; Part that device of the present utility model adopts is the simple conventional mechanical structure of structure, and common process equipment can realize, and installation and removal do not need to prepare special tool yet, and conventional conventional tool can realize the dismounting of this device.
