Technical field
The utility model relates to blade adjustable shaft flow fan field, particularly relates to a kind of adjustment and the feedback means that regulate the oil hydraulic cylinder of fan blade.
Background technique
Axial-flow blower can be carried gas and improve gas pressure, is widely used in industries such as the mining of national economy, metallurgy, chemical industry, refrigeration, power and metallurgy.When the pipeline dynamic characteristic changing of work system, during the flow pressure that particularly actual conditions is higher than design conditions requirement, for keeping the efficiency of blower fan, generally change fan blade by hydraulic cylinder device, namely movable vane or quiet leaf divergence regulate, therefore oil hydraulic cylinder all has the input and output device of regulated signal, and signal input apparatus makes oil hydraulic cylinder start action, and output unit makes adjustment personnel know the degree of adjustment and whether complete adjustment by the output signal of feedback.
Existing blade adjustable shaft flow fan hydraulic regulation and feedback means, as shown in Figure 1, its input guide rod is that the electric actuator 2 being fixed on fan casing 1 outside drives, input guide rod is to hydraulic pressure installation 6 input signal, hydraulic pressure installation 6 action, the output guide rod simultaneously causing the drive of the feedback mechanism of hydraulic pressure installation 6 to pass casing runner equally rotates outside transmission of signal, and the signal of transmission is finally presented on the indicating device outside casing 1.Input guide rod and output guide rod outside generally all also need to arrange a steel tube dirt-proof boot 3, this makes the occupied ratio of casing flow channel space increase, casing flow channel space is occupied, increase flow resistance, reduce overall efficiency, simultaneously, a vibration stimulus source is added because casing flow channel space is taken by major part, add the probability of blade vibration, shorten the fatigue life of blade most probably, affect the safety of fan operation.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of blade adjustable shaft flow fan hydraulic regulation feedback means, at least one stator is arranged to hollow stator by this device, elastic cable paper and input guide rod are all arranged in the inner chamber of hollow stator, additionally would not take the flow channel space of fan casing like this, adjusting feedback device can not form independent vibrational excitation, while making flowing space smoothness in casing, improving overall efficiency, also assures that safety in operation and the life-span that improve blade.
The utility model is achieved in that a kind of blade adjustable shaft flow fan hydraulic regulation feedback means, comprise electric actuator, input guide rod, stator and hydraulic pressure installation, described electric actuator is fixedly mounted on fan casing outside, electric actuator exports rotation angle signal by input guide rod to hydraulic pressure installation, this adjusting feedback device also includes feedback indicator, described stator is hollow stator, described input guide rod is arranged in stator, described hydraulic pressure installation is provided with feedback output unit, described feedback indicator is provided with feedback reception unit, described feedback output unit matches with feedback reception unit.
