Description

A kind of wind motor leaf angle automatic regulating device
Technical field
The utility model relates to a kind of axial flow blower component, in particular to a kind of wind motor leaf angle automatic regulating device.
Background technique
Axial flow blower is widely used in the industry, can be accurate by changing the angle of its blade when axial flow blower operates Change its air quantity, wind pressure, power, and be widely used in the cooling of large scale equipment.Due to needing accurate control, and automatically controlled interference It is larger, therefore the blade angle of axial flow blower is mainly controlled by being installed on the servo-cylinder in blower centre, staff It not only needs to control servo-cylinder movement and also adjusts blade angle size, it is also necessary to which the moment grasps each real-time blade of blower and opens Degree, therefore servo-cylinder also needs to match corresponding monitoring system.
Since blower interior wind-force is big, air quality is very poor, and has electronic interferences, therefore it is difficult to install electrically controlled monitoring equipment Degree is big, and monitoring accuracy is poor, sometimes even can not complete feedback data, monitoring device now is mostly mechanical, electronic execution Device moves along a straight line to control cylinder action by rotation driven gear rack drives spool, and such control mode was mechanically connected In cumbersome, so that its control misses by a mile, high failure rate;Due to Electric Actuator output shaft and Mechanical course servoBcylinder input shaft Rigid connection, concentricity bad guarantee when leading to its assembly is easy stuck, damages the sealing on input shaft, Electric Actuator peace Very big danger and difficulty are brought to repair and maintenance mounted in high-altitude.
In continual rotation for a long time, big due to shaking, the mounting parts between oil cylinder and blower can not be kept away That exempts from will appear loosening, obscission, according to mechanical structure, once have loose phenomenon, rigid connector will transient breakdown, Not only itself loss is big, and more seriously the external world can not continue adjustment monitoring, causes blower uncontrollable, staff can not obtain Know the damaged condition of oil cylinder and executing agency, can not also learn the state of blade, can only maintenance down, to cause greatly to pass through Ji loss.
Summary of the invention
In view of the deficiencies of the prior art, the utility model provides a kind of wind motor leaf angle automatic regulating device.
The technical solution adopted in the utility model is: a kind of wind motor leaf angle automatic regulating device, including servo-cylinder, The first oil duct is arranged in the servo-cylinder, and the second oil duct is connected to its internal two-piston chamber, the servo-cylinder piston rod respectively Blade connection, first oil duct are installed, the second oil duct is set in piston rod, wherein the first oil duct is located in piston rod Center portion position, the piston rod Matching installation have a hydraulic rotary joint and displacement sensor, institute's displacement sensors measuring staff access the In one oil duct, setting and the matched magnet ring of the measuring staff in the servo-cylinder cylinder body.
A kind of wind motor leaf angle automatic regulating device, it is characterized in that: the electronics storehouse of institute's displacement sensors Equipped with pickup dust-proofing part.
A kind of wind motor leaf angle automatic regulating device, it is characterized in that: the rear end cap of the servo-cylinder is arranged There is rear end cap to expand part, the rear end cap expands part and is provided with sensor measuring staff expansion hole.
The utility model enables sensor measuring staff to be set to oil duct by the way that oil cylinder oil duct position to be set on piston rod It is interior, to realize built in displacement sensor, to adapt to bad working environments, mechanical structure is thoroughly abandoned, realizes electronic monitoring, it is internal Electronic structure is simple, it is only necessary to which one group of conducting wire can connect, strong antijamming capability, and greatly reduce quality and volume, oil cylinder Integrated with sensor, failure rate can decline 80% or more, even if there is partial exfoliation phenomenon, will not damage sensor, and still It can normally monitor, later period maintenance difficulty, maintenance time substantially reduces, to reduce use cost.
