Description
Technical field
The present invention relates to a kind of steering engines to belong to more specifically to a kind of rotary vane type steering gear with leakage compensation function
In marine machinery technical field.
Background technique
Rotary vane type steering gear is a kind of common marine machinery, is often configured on each type ship and self-propulsion apparatus, for protecting
It holds or changes direction of ship travel, guarantee navigation safety.
Existing rotary vane type steering gear includes come about mechanism, hydraulic power unit, electric control system, and coming about for rotary vane type steering gear is dynamic
Work is that the pressure difference promotion between the height pumping cavity by the mechanism that comes about comes about what mechanism generated.But two connected height
Phenomenon is let out in would generally occurring between pumping cavity, with the raising of operating pressure, often leakage rate straight line increases, when serious even
It will lead to the underspeed of coming about of steering engine, or there is a phenomenon where " running rudder "；Meanwhile excessive interior let out limits rotary vane type steering gear
Lightweight and to enlarged marine equipment.
Summary of the invention
The present invention is directed to existing for existing rotary vane type steering gear the problems such as coming about underspeed or " running rudder " occurs, and mentions
For a kind of rotary vane type steering gear with leakage compensation function.
To achieve the above object, the technical solution of the invention is as follows: a kind of rotary blade type rudder with leakage compensation function
Machine, including the mechanism that comes about, hydraulic power unit, electric control system, the hydraulic power unit and the mechanism that comes about are connected by fluid pressure line
It connects, it further includes having leakage compensation mechanism that the electric control system is electrically connected with hydraulic power unit, the leakage compensation mechanism
Including variable-frequency motor and hydraulic pump, the variable-frequency motor and hydraulic pump are connect with electric control system respectively, are come about in mechanism
Steering engine ultramagnifier and rudder angle signalling generator connect respectively with electric control system signal, on the high-low pressure oil circuit of the mechanism that comes about
It is respectively arranged with pressure sensor, the pressure sensor on the high-low pressure oil circuit is electrically connected with electric control system respectively.
Pressure difference between the upper high-low pressure oil circuit of the mechanism that comes about is 5Mpa.
Between the actual rudder angle signal of the steering engine ultramagnifier acquisition and the ordered rudder angle signal of rudder angle signalling generator acquisition
Differential seat angle is 1 °.
The cabinet of the mechanism that comes about is mounted on hull pedestal.
The leakage compensation mechanism is mounted on the cabinet exterior for the mechanism that comes about.
Compared with prior art, the beneficial effects of the present invention are:
In the present invention, when rotary vane type steering gear because leak compensation can will be leaked into low by high pressure chest when pressure difference leads to interior let out
The hydraulic oil of pressure chamber refills high pressure chest again, avoids occurring rotary vane type steering gear and comes about underspeed or that " run about rudder " occurs is existing
As.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Fig. 2 is transfer steering engine structure hydraulic schematic diagram of the present invention.
In figure, the mechanism that comes about 1, hydraulic power unit 2, electric control system 3, rudder angle ultramagnifier 4, rudder angle signalling generator 5, pedestal 6,
Variable-frequency motor 7, hydraulic pump 8, cabinet 9.
Specific embodiment
Below in conjunction with Detailed description of the invention and specific embodiment, the present invention is described in further detail.
Referring to Fig. 1 to Fig. 2, a kind of rotary vane type steering gear with leakage compensation function, including come about mechanism 1, hydraulic power unit
2, electric control system 3 and leakage compensation mechanism, the hydraulic power unit 2 is connect with the mechanism 1 that comes about by fluid pressure line, described
Electric control system 3 be electrically connected with hydraulic power unit 2.The hydraulic power unit 2 has the pump group of two groups of mutual backup, the electric-controlled
System 3 processed is for driving and controlling the hydraulic power unit 2 and the mechanism 1 that comes about.
Referring to Fig. 1 to Fig. 2, the pressure of the high-low pressure oil circuit of the mechanism that comes about 1 inputs to electrically in real time by pressure sensor
Control system 3.The ordered rudder angle signal that the actual rudder angle signal and rudder angle signalling generator 5 that steering engine ultramagnifier 4 acquires acquire is defeated in real time
Enter to electric control system 3.
Referring to Fig. 1 to Fig. 2, specifically, the cabinet 9 of the mechanism 1 that comes about is mounted on hull pedestal 6.
Referring to Fig. 1 to Fig. 2, specifically, the leakage compensation mechanism is mounted on 9 outer wall of cabinet for the mechanism 1 that comes about.
Referring to Fig. 1 to Fig. 2, when the mechanism 1 that comes about rotates, if the difference for the high-low pressure oil circuit that electric control system 3 receives
Value is more than 5Mpa, then electric control system 3 drives variable-frequency motor 7 and hydraulic pump 8, and hydraulic oil is mended from low pressure line to high-voltage tube
Road.
Referring to Fig. 1 to Fig. 2, when the mechanism 1 that comes about stops, if the actual rudder angle signal that receives of electric control system 3 with
Ordered rudder angle signal difference is more than 1 °, then electric control system 3 drives variable-frequency motor 7 and hydraulic pump 8, and hydraulic oil is mended to reduction
