Detailed description

La bomba reversible hidràulica Raymarine T1 12V (M81120) està dissenyada per operar el mecanisme de direcció d'una embarcació dins d'un sistema de pilot automàtic Raymarine. Aquest model està principalment destinat a embarcacions equipades amb un sistema de direcció hidràulica existent, o pot utilitzar-se amb una direcció mecànica en associació amb un cilindre secundari. El motor de 12V DC amb imant permanent disposa d'una classificació IP67, assegurant una protecció contra la immersió temporal i la pols, i pot retirar-se de la bomba sense introduir aire al sistema hidràulic ni provocar fuita de fluid.

Capacitats tècniques

La bomba T1 (M81120) és compatible amb els cilindres hidràulics d'efecte simple o doble, cobrint una capacitat de 80 a 230 cc. Proporciona un cabal màxim de 1000 cc/min (sense càrrega) i suporta una pressió intermitent màxima de 55 bar (800 psi) a 12V. El consum de corrent típic és de 19 A a 12V i 55 bar. Les vàlvules antiretorn pilotades integrades impedeixen que la bomba sigui moguda pel sistema de direcció manual o per la càrrega del timó, garantint una estabilitat de rumb. Aquest model també és compatible amb sistemes amb dipòsit a pressió i està protegit per a ús en compartiments motor.

Posicionament en la gamma Raymarine

La bomba Raymarine T1 12V (M81120) es posiciona com una solució intermèdia en la gamma de bombes hidràuliques Raymarine. Ofereix una capacitat i un cabal superiors a la bomba Tipus 0.5 (E12139), la qual té una capacitat de cilindre de 50-110 cc i un cabal de 600 cc/min. En canvi, els models Tipus 2 (M81121 12V, M81123 24V) i Tipus 3 (M81122 12V, M81124 24V) estan dissenyats per a cilindres de major capacitat, que van de 230-350 cc per al Tipus 2 i 350-500 cc per al Tipus 3, amb cabals màxims de 2300 cc/min i 3100 cc/min respectivament. El model T1 12V (M81120) representa un equilibri entre rendiment i compactesa per a una àmplia gamma d'embarcacions d'esbarjo.
Totes les bombes Raymarine d'aquesta sèrie comparteixen característiques comunes com la conformitat amb les normes CE 2004/108/EC (EMC) i 94/25/EC (RCD), així com una protecció IP67.

« Analysis of the Raymarine T1 12V hydraulic pump »

The Raymarine T1 12V hydraulic pump (M81120) is a fundamental component for autopilot systems on a wide range of recreational vessels, typically those equipped with medium-sized steering cylinders. Its capacity to handle cylinders from 80 to 230 cc makes it suitable for cruising sailboats or motorboats of approximately 8 to 12 meters, where manoeuvring requirements demand more power than a 0.5 model but do not reach the needs of very large vessels. The 12V DC choice is standard and simplifies electrical integration on most boats.

Installing this pump requires absolute cleanliness of the hydraulic circuit to prevent contamination of the integrated check valves, which is critical for system reliability. Although the motor is rated IP67, it is recommended to install it in a dry, ventilated compartment, away from heat sources and excessive vibrations, to maximize its lifespan and the stability of hydraulic connections. This pump must be considered as a secondary steering system drive, not as a replacement for the primary system, in accordance with the manufacturer's safety guidelines.

Compared to Raymarine type 2 or 3 pumps, the T1 12V offers an optimal compromise in terms of size, electrical consumption, and delivered power, making it relevant for boats where the cylinder does not justify the higher flow rate of top-tier models. For a successful installation, using high-quality hydraulic fittings and hoses is essential, along with thorough bleeding of the circuit after assembly.

What is the main function of the Raymarine T1 reversible pump - 12V (M81120)?

The Raymarine T1 reversible pump - 12V (M81120) is designed to operate the steering mechanism of a vessel within a Raymarine autopilot system. It is primarily intended for boats equipped with an existing hydraulic steering system. It can also be used on a mechanically steered vessel in conjunction with a secondary cylinder.

With which types of hydraulic rams is the T1 pump (M81120) compatible?

The Raymarine T1 pump (M81120) is compatible with single-acting or double-acting hydraulic rams. It is specifically designed for rams with a displacement between 80 and 230 cc (4.9 to 14.0 cubic inches).

What are the performance specifications of the T1 reversible pump - 12V?

The Raymarine T1 - 12V pump (M81120) delivers the following performance specifications at its nominal voltage:

Peak flow rate (no load): 1000 cc/minMaximum intermittent pressure (at 12 V): 55 bar (800 psi)Typical current draw (at 12 V and 55 bar): 19 A

Where and how should I install the Raymarine T1 hydraulic pump?

The pump is designed exclusively for installations below deck. It must be secured to a substantial structure to prevent vibrations that could damage the hoses. It must be mounted away from heat sources, excessive vibrations, and fumes, and must under no circumstances be installed in confined areas containing flammable materials. It is also recommended to install it above the waterline.

Is the T1 pump (M81120) protected against water and dust?

Yes, the Raymarine T1 pump (M81120) has an IP67 rating. This means it is protected against temporary immersion in water and against dust. The motor can be removed from the pump without introducing air into the hydraulic system or causing fluid leakage.

What are the EMC (Electromagnetic Compatibility) installation guidelines for the Raymarine T1 pump?

To ensure optimal performance in terms of electromagnetic compatibility (EMC), Raymarine equipment and its cables should be:

At least 1 meter (3 feet) away from any equipment transmitting or cables carrying radio signals (e.g., VHF radios, cables, and antennas). For SSB radios, this distance must be increased to 2 meters (7 feet).More than 2 meters (7 feet) from the path of a radar beam.Powered by a separate battery from the one used for engine starting to prevent erratic behavior and data loss.It is also recommended to use the cables specified by Raymarine and not to cut or extend them unless detailed in the installation manual.
