Description détaillée

Performanțe și integrare mecanică

Vérinul liniar mecanic tip 2 scurt 24V Raymarine este un actuator pentru pilot automat de înaltă performanță, conceput pentru ambarcațiuni cu vele și bărci rapide care necesită o forță de împingere semnificativă. Spre deosebire de modelele de tip 1, acest vérin de tip 2 oferă o robustețe superioară pentru sistemele de direcție solicitante, păstrând totodată un format compact de instalare datorită cursei de 300 mm. Alimentat la 24V, se integrează perfect cu calculatoarele de cap Raymarine (precum seriile ACU sau SPX) pentru a asigura o reacție rapidă și precisă a cârmei.

Instalare și geometrie a cârmei

Acest vérin mecanic acționează direct asupra sectorului de cârmă sau brațul de eche. Instalarea necesită o aliniere riguroasă pentru a garanta o eficiență mecanică maximă: brațul de împingere trebuie să fie strict perpendicular pe brațul de eche atunci când cârma este în poziție centrală (variația de aliniere tolerată este mai mică de 5 grade). Cu o greutate de 7,72 kg, construcția sa industrială necesită o fixare pe o structură capabilă să absoarbă sarcini importante. Pentru menținerea performanțelor optime, Raymarine recomandă o revizie completă la fiecare 1000 de ore de utilizare sau o dată la 2 ani.

Cerințe electrice și cablare

Pentru a asigura o alimentare stabilă la 24V fără căderi de tensiune (care ar putea reseta sistemul), dimensionarea cablurilor este esențială. Conform specificațiilor de instalare ale producătorului, este necesară o secțiune de 4 mm² (12 AWG) pentru lungimi de până la 3 metri, 6 mm² (10 AWG) până la 5 metri, respectiv până la 16 mm² (6 AWG) pentru lungimi de până la 16 metri. Respectarea acestor secțiuni și a directivelor de instalare CEM (menținerea unei distanțe de cel puțin 1 metru față de cablurile VHF și 2 metri față de semnalele BLU) asigură o imunitate totală la interferențe radio.

« Mechanical reliability and 24V electrical optimization for demanding steering systems »

The Raymarine Type 2 mechanical linear actuator (M81133) is the industrial standard for cruising sailboats and medium-displacement vessels up to 15,000 kg. Operating at 24V, this electromechanical power unit is designed to deliver flawless reliability and absolute control during long offshore passages. Mechanically, it delivers an impressive maximum thrust of 480 kg and handles a rudder torque of up to 1,190 Nm, ensuring authoritative course holding even in rough seas.

The internal design of this actuator combines a high-power electric motor, a high-strength belt drive, and a precision epicyclic gearbox. This setup ensures an extremely fast port-to-starboard response time of just 11 seconds. One of its key advantages in navigation is its built-in fail-safe electromagnetic clutch. When the autopilot is in standby, this clutch instantly disengages the mechanism, providing minimal mechanical resistance (back-drive force). This completely preserves the smoothness of manual steering, with no friction or motor-related resistance.

In terms of system integration, its compact 300 mm stroke makes it a strategic solution for tight helm spaces while maintaining high-level performance. It interfaces optimally with the Raymarine Evolution ACU-400 control unit. Regarding installation, it is critical to note that the mechanical stresses generated by this actuator require mounting on a floor beam or a substantial vessel structure. Rigorous geometric alignment with the independent tiller arm or quadrant is mandatory, as the spherical joint allows a maximum misalignment of +/- 5 degrees. With an average power consumption between 66 and 96 W and exceptionally quiet operation, this actuator is the preferred choice for 24V integration combining endurance, power, and discretion.

Questions fréquentes

Besoin d'aide ? Contactez-nous

What type of boat is the Type 2 short mechanical linear actuator designed for?

This Raymarine actuator (reference M81133) is designed for sailboats and motorboats requiring high thrust force for their steering system.

What is the stroke length of this Raymarine linear actuator?

The standard Type 2 short model has a 300 mm stroke, allowing it to maintain a compact installation format while delivering high mechanical performance.

What is the supply voltage for this model?

This mechanical linear actuator operates exclusively at 24V.

Which autopilot computers is this linear actuator compatible with?

It integrates seamlessly with Raymarine autopilot computers, including the ACU or SPX series, to ensure fast and highly accurate rudder response.

How should the ram be aligned relative to the rudderstock?

Installation requires precise alignment. The pushrod must be strictly perpendicular to the tiller arm when the rudder is in the central position. The allowed alignment variation is less than 5 degrees.

On which part of the steering system does the ram act?

This mechanical actuator acts directly on the tiller sector or the rudder arm of your boat.

What is the weight of the M81133 ram?

The cylinder alone weighs 7.72 kg. Due to this weight and the thrust force exerted, it must be mounted on a very solid structural base.

What is the recommended maintenance interval for this hydraulic ram?

Raymarine recommends a full service by an authorized dealer every 1,000 hours of use or every 2 years, whichever comes first.

Which cable section to use for a 3-meter distance?

For a 24V installation with cable length up to 3 meters, a 4 mm² (12 AWG) cross-section is required to prevent voltage drops.

What wiring is required for a 5-meter distance?

If the power cable length reaches 5 meters, the manufacturer's specifications require the use of a 6 mm² (10 AWG) cable.

What cable size is required for a 10-meter installation?

For a distance up to 10 meters at 24V, you must use cables with a cross-section of 10 mm² (8 AWG).

At what distance from a VHF radio should the hydraulic ram be installed?

To avoid electromagnetic interference, the actuator must be installed at least 1 meter (3 feet) away from any equipment or cables transmitting radio signals, such as a VHF.

Should the hydraulic ram be kept away from an HF radio (SSB)?

Yes, for HF radios (SSB), the minimum separation distance from the hydraulic ram must be increased to 2 meters (7 feet).

Can I connect the hydraulic ram to the engine starter battery?

No, it is strongly recommended to power the equipment from a dedicated battery. Voltage drops during engine start (below 10V) could cause the autopilot system to reset.

Can this actuator be used on a 12V electrical system?

No, the M81133 reference is specifically designed for 24V systems. If you have a 12V network, you will need to use the corresponding cylinder reference (M81131).

What are the installation precautions regarding a radar?

The actuator must be installed more than 2 metres (7 feet) from the radar beam path to avoid any electromagnetic interference.

What is the main difference between a type 1 cylinder and this type 2 cylinder?

Unlike type 1 models, the type 2 actuator offers superior robustness and greater thrust force, making it suitable for heavier and more demanding steering systems.

Does the cylinder mounting structure need to be reinforced?

Yes, the industrial design of this hydraulic ram generates very high thrust forces. It therefore requires mounting on a structure capable of absorbing heavy loads. If in doubt, consult the manufacturer of your steering system.

Is it possible to cut and extend the supplied power cables?

It is not recommended to cut and splice the cables specified by Raymarine, as this may compromise electromagnetic compatibility (EMC) performance, unless the procedure is explicitly detailed in the installation manual.

What cable section is required for a very long distance (up to 16 meters)?

For a very distant installation, up to 16 meters at 24V, it is imperative to use thick wiring, specifically 16 mm² (6 AWG), to ensure stable power supply to the actuator.
