Description
The utility model relates to a kind of air cooling device angle of fan leaves controlling device, belongs to the blade control device of the axial-flow pump that is exclusively used in elastic fluid, the angle that can regulate fan blade automatically with working condition and variation of ambient temperature.
Air cooling device blower fan in the past mostly is the permanent wind amount blower fan of stator blade, and in order to satisfy the requirement of maximum amount of cooling water, blower fan need be operated under the maximum power state always, wastes a large amount of energy, and causes the medium temperature instability, and influence is produced.In the prior art, have the pneumatic paddle angle regulator in the more advanced air cooling device blower fan, form by casing, pneumatic positioning component, plate-like executive component, blade rotor, blade etc.Blade rotor is installed in the hub portion of casing, blade is fixed on its outer end, the eccentric pin that the inner has an axis to parallel with this blade rotor axis, eccentric pin insert the annular groove that is positioned at the perpendicular plate-like executive component periphery of its axis of casing and blade rotor axis.The plate-like executive component moves up and down, and drives the rotating shaft of eccentric pin rotation blade, regulates the angle of inclination of the blade that is installed on the blade rotor outer end.Existing deficiency is: pneumatic positioning component part-structure complexity, and cooperatively interacting between several springs is difficult to regulating and controlling in it, and diaphragm of rubber is easily aging, influences working life.In addition, the shortcoming of pneumatic low speed own or load variations time running poor stability also must be reflected in the blade control device.
The purpose of this utility model provide a kind of simple in structure, be easy to regulate control, easy to maintenance, long service life, the stable air cooling device angle of fan leaves controlling device of running, with working condition and the automatic adjusting vane angle of variation of ambient temperature.
The purpose of this utility model is achieved in that
A kind of air cooling device angle of fan leaves controlling device, comprise casing, the plate-like executive component, blade rotor, blade etc., blade rotor is installed on the hub portion of casing, blade is fixed on its outer end, there is the eccentric pin of an axis and this blade rotor parallel axes the inner, eccentric pin inserts the annular groove that is positioned at the perpendicular plate-like executive component periphery of its axis of casing and blade rotor axis, the upper end is equipped with an oil hydraulic cylinder with plate-like executive component coaxial line in the casing, hydraulic cylinder piston rod and plate-like executive component are connected, and between plate-like executive component and its below casing preloading spring are installed.
On the same circumference of plate-like executive component lower surface equally distributed directional post is installed, directional post stretches in its below pilot hole on casing and is slidingly matched with pilot hole.
The end that blade rotor is positioned at casing be equipped with one with the disk that has eccentric pin of its coaxial line, the axis of eccentric pin parallels with the blade rotor axis.
Blade is to be fixed on the blade rotor outer end by the flange plate that is installed on the blade rotor.
The advantage that the utility model is compared with prior art had is: simple in structure, be easy to regulate control, easy to maintenance, easy aging rubber spare in the no pneumatic paddle angle regulator, improved working life, it has good run stability hydraulic transmission decision itself.Under the automatic controlling system of forming by process computer, PIC regulator etc., can realize of the automatic adjusting of air cooling device angle of fan leaves with working condition and variation of ambient temperature.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Fig. 1 is the structure diagram of the utility model air cooling device angle of fan leaves controlling device.
Fig. 2 is 1 A-A sectional view.
As shown in Figure 1 the utility model air cooling device angle of fan leaves controlling device mainly by casing 1, oil hydraulic cylinder 2, plate-like executive component 3, blade rotor 4, be with eccentric pin disk 4b, flange plate 5, blade 6, directional post 7, preloading spring 8 etc. to form.Blade rotor 4 is installed on the wheel hub 1a part of casing 1.Blade 6 is fixed on blade rotor 4 outer ends by the flange plate 5 that is installed on blade rotor 4 three.Unclamp the attachment bolt between blade 6 and the flange plate 5, promptly rotatable vane 6, and the angle of blade 6 is carried out coarse adjustment.Blade rotor 4 the inners be equipped with one with the disk 4b that has eccentric pin 4a of its coaxial line, the axis of eccentric pin 4a parallels with the axis of blade rotor 4, sees Fig. 2.Eccentric pin 4a inserts the annular groove that is positioned at perpendicular plate-like executive component 3 peripheries of casing 1 its axis and blade rotor axis.Casing 1 upper end and plate-like executive component 3 coaxial lines are equipped with an oil hydraulic cylinder 2, and the piston rod of oil hydraulic cylinder 2 and plate-like executive component 3 are connected.Between plate-like executive component 3 and its below casing 1 preloading spring 8 is installed.On the same circumference of plate-like executive component 3 lower surfaces equally distributed directional post 7 is installed, directional post 7 stretches in its below pilot hole on casing 1 and is slidingly matched with pilot hole, makes the motion of plate-like executive component 3 more steady.
During work, motor drives the main shaft 10 that is supported on the base 9 through the pulley decelerates machine and rotates.Main shaft 10 drives blower fan by the supporting disk 1b of casing 1 below, makes blade 6 produce rotatablely moving around the blower fan axis.Usually executive component 3 keeps balance in the hydraulic coupling of oil hydraulic cylinder 2 piston rod transmission and below it under preloading spring 8 effects, makes fan blade 6 fixed angle in certain certain value.When variation of ambient temperature or process parameter change, cause that air cooling device outlet medium temperature changes, this information machine is as calculated handled, and is sent to PID.Handle through PID, output a control signal to hydraulic system,, oil hydraulic cylinder 2 pistons are subjected to displacement, drive plate-like executive component 3 and move by electro-hydraulic proportional valve.Plate-like executive component 3 moves up and down and changes into the rotation of eccentric pin 4a around blade rotor 4 axis, and drive vane rotating shaft 4 is rotated.Blade 6 is connected with blade rotor 4, thereby the rotation of blade rotor 4 just makes the angle of blade 6 adjusted.
