Description
Hydraulisk servomotor-styresystem.Hydraulic servo motor control system.
Oppfinnelsen vedrører hydrauliske styresystemer, primært beregnet for servostyring av stillbare propellere, styremaskiner, stråleror og annet utstyr. The invention relates to hydraulic control systems, primarily intended for servo control of adjustable propellers, steering machines, thrusters and other equipment.
Det er kjent et servo-styresystem (Escher Wyss) som benyttes for stillingsregulering av innstillbare propellvinger. Slike systemer innbefatter komplekse og heterogene styrearrange-menter innbefattende en dobbeltvirkende hydraulisk servomotor av stempeltypen, hvilken servomotor betjenes av olje som sirku-leres ved hjelp av en flerstempel-radialpumpe som reguleres med hjelpehydraulikk som styres i fra en pneumatisk-hydraulisk styr-ingsregulering. Flerstempelpumpen drives av en elektromotor med konstant turtall. A servo control system (Escher Wyss) is known which is used for position regulation of adjustable propeller blades. Such systems include complex and heterogeneous control arrangements including a double-acting hydraulic servo motor of the piston type, which servo motor is operated by oil that is circulated by means of a multi-piston radial pump that is regulated with auxiliary hydraulics that is controlled from a pneumatic-hydraulic steering control. The multi-piston pump is driven by an electric motor with constant speed.
Den pneumatisk-hydraulisk stillingsregulerer, som sammenligner det innstilte pneumatiske signal for den ønskede propellvingestigning med et hydraulisk signal som indikerer den virkelige stigning, tilveiebringer et styresignal for hjelpe-hydraulikken som på sin side 'omdanner signalet til en lineær for-skyving av det element som regulerer leveringen fra flerstempelpumpen. Det hydrauliske målesignal blir i tillegg omdannet i en diferensialtrykk-transmitter til et elektrisk utgangssignal for måleinstrumenter som overvåker den virkelige propellvingestigning . The pneumatic-hydraulic position controller, which compares the set pneumatic signal for the desired propeller blade pitch with a hydraulic signal indicating the actual pitch, provides a control signal for the auxiliary hydraulics which in turn 'converts the signal into a linear advance of the element which regulates the delivery from the multi-piston pump. The hydraulic measurement signal is additionally converted in a differential pressure transmitter into an electrical output signal for measuring instruments that monitor the actual propeller blade pitch.
Ifølge oppfinnelsen benyttes det en SCR-(halvleder-styrt.forsterker) krets med to innganger i startkretsen for den elektriske motor som styrer den hydrauliske servomekanisme. En av SCR-krets-inngangene er forbundet med en elektromekanisk transduser som mottar de manuelt eller automatisk innstilte signaler. Den andre inngangen i kretsen er, for å sikre en difer-ensialvirkning - forbundet med den .elektromekaniske transduser som følger stemplets virkelige bevegelse i servomotorsylinderen. According to the invention, an SCR (semiconductor controlled amplifier) circuit with two inputs is used in the starting circuit for the electric motor that controls the hydraulic servo mechanism. One of the SCR circuit inputs is connected to an electromechanical transducer that receives the manually or automatically tuned signals. The other input in the circuit is, to ensure a differential action - connected to the electromechanical transducer which follows the actual movement of the piston in the servo motor cylinder.
i in
En informasjonsstrøm med hensyn til stempelstill-ingen i servomotorsylinderen til SCR-kretsen via den elektromekaniske transduser oppnås ved en mekanisk kobling av trans-duseren og stempelstangen, utført med egnede bevegelsesledd. An information flow with regard to the piston position in the servomotor cylinder of the SCR circuit via the electromechanical transducer is obtained by a mechanical coupling of the transducer and the piston rod, made with suitable movement joints.
En fordel med det nye system er at det er mulig å oppnå en enhetlig styring av den hydrauliske servo via den direkte elektro-hydrauliske virkning, uten ekstra mellomliggende styreanordninger.' Systemet får derfor en enkelt utførelse, stor nøyaktighet og hurtig utførelse av servomotor-fjernstyringen for stillingsregulering av de styrte elementer innenfor det ønskede område. Systemet har lave drifts- og grunnlagsomkostninger. An advantage of the new system is that it is possible to achieve uniform control of the hydraulic servo via the direct electro-hydraulic effect, without additional intermediate control devices.' The system therefore has a simple design, high accuracy and fast execution of the servo motor remote control for position regulation of the controlled elements within the desired range. The system has low operating and basic costs.
Det er også med det nye system tilveiebragt en mulighet for bruk av identiske komponenter og enheter i arrangementet som innbefatter regulerbare propeller og styrmaskiner. The new system also provides an opportunity to use identical components and units in the arrangement, which include adjustable propellers and steering engines.
Oppfinnelsen skal beskrives nærmere under henvisning til tegningen som viser et hydraulisk servomotor-styresystem. The invention shall be described in more detail with reference to the drawing showing a hydraulic servo motor control system.
På tegningen er det vist en dobbeltvirkende hydraulisk sylinder 3 hvor stemplets 2 bevegelse tilveiebringer et arbeidsmediumtrykk i sirkulasjonssystemet for pumpen 1, med re-versibel rotasjon og regulerbar vinkelhastighet. Pumpen 1.. drives direkte av en elektromotor 4 hvis startkrets er tilknyttet SCR-enheten 5. Denne enhet har to innganger. Den ene inngang er forbundet med en elektromekanisk transduser 6 som omdanner de manuelt eller automatisk innstilte signaler (ordrer) fra skipets styrepult. Den andre inngangen er tilknyttet en elektromekanisk transduser 7 som følger bevegelsen til stemplet 2 i servomotorsylinderen 3. Således er den elektromekaniske transduser 7 mekanisk sammenkoblet med stempelstangen ved hjelp av en egnet mekanisk forbindelse. SCR-enheten 5 mottar elektriske signaler fra transduserne 6 og 7, og i samsvar med forskjellen mellom den innstilte verdi og stemplets 2 virkelige stilling i sylinderen 3 påvirkes så den elektriske motor 4. Den elektriske motor 4 driver pumpen 1 som tilveiebringer ønskede endringer i stemplets 2 stilling i forhold til sylinderen 3, hvorved arbeidsbetingel-sene forandres. The drawing shows a double-acting hydraulic cylinder 3 where the movement of the piston 2 provides a working medium pressure in the circulation system for the pump 1, with reversible rotation and adjustable angular speed. The pump 1.. is driven directly by an electric motor 4 whose starting circuit is connected to the SCR unit 5. This unit has two inputs. One input is connected to an electromechanical transducer 6 which converts the manually or automatically set signals (orders) from the ship's control desk. The second input is connected to an electromechanical transducer 7 which follows the movement of the piston 2 in the servomotor cylinder 3. Thus, the electromechanical transducer 7 is mechanically connected to the piston rod by means of a suitable mechanical connection. The SCR unit 5 receives electrical signals from the transducers 6 and 7, and in accordance with the difference between the set value and the actual position of the piston 2 in the cylinder 3, the electric motor 4 is then affected. The electric motor 4 drives the pump 1 which provides desired changes in the piston's 2 position in relation to the cylinder 3, whereby the working conditions change.
