Detailed description

Črpalka za dvojni tok Raymarine T2 12V (referenčna številka M81121) je namenjena upravljanju krmilnega mehanizma plovil v okviru avtopilota Raymarine. Predvsem je namenjena čolnom, ki so opremljeni z obstoječim hidravličnim krmilnim sistemom, lahko pa se uporablja tudi na plovilih z mehanskim krmilom v kombinaciji z sekundarnim krmilnim cilindrom. V primerjavi s črpalko Tip 0.5 (50-110 cc) in Tip 1 (80-230 cc) ima Tip 2 povečan kapacitet cilindra od 230 do 350 cc, kar jo uvršča v srednje velike do velike krmilne sisteme, medtem ko je Tip 3 (350-500 cc) namenjen največjim cilindrom.

Tehnične značilnosti in integracija

Ta črpalka je poganjana z motorjem s trajno magnetno vzbujo (12 V DC) in vključuje pilotirane protitlačne ventile, ki preprečujejo vračanje ročnega krmilnega sistema ali obremenitve krmila. Z razredom zaščite IP67 je motor odporen na vodo in ga je mogoče odstraniti iz črpalke brez vdora zraka v hidravlični sistem ali izlitja tekočine. Kompatibilna je z uravnoteženimi in neuravnoteženimi cilindri in jo je mogoče uporabljati z sistemi s tlačnim rezervoarjem.

Zmogljivost in skladnost

Črpalka za dvojni tok Raymarine T2 dosega vršni pretok 2300 cc/min (v praznem teku) in vzdržuje največji prekinjen tlak 55 barov (pri 12 V). Običajni tok pri 12 V in 55 barih je 24 A. Vsi priključki so tipa 1/4 palca BSPP. Namenjena je za namestitev pod palubo in je zaščitena za uporabo v motornih predelih. Ta izdelek je v skladu z direktivami EU 2004/108/EC (EMC), EN60945:2002, 94/25/EC (RCD), EN28846:1993 in EN ISO 10592:1995.

« Technical analysis of the Raymarine T2 12V hydraulic pump »

The Raymarine Type 2 reversible hydraulic pump, model M81121, is a critical component for integrating an autopilot system on sailboats and motorboats equipped with hydraulic steering. With a cylinder capacity ranging from 230 to 350 cc, it is ideally suited for mid-sized vessels, offering a balance between power and space requirements. It differs from the Type 1, which is more compact (80-230 cc), and is designed for applications where the Type 3 (350-500 cc) would be oversized.

This pump must be installed below deck on a sturdy structure to minimize vibrations that could affect the longevity of hydraulic hoses. Absolute cleanliness is required when handling fittings and hoses to prevent system contamination, which could compromise the function of the integrated non-return valves. For optimal EMC performance, connection to a battery separate from the engine starter battery is recommended. While the installation manual is detailed, intervention by a Raymarine-certified technician is strongly advised to ensure system safety and performance.

This pump is not intended as a replacement for the primary steering system but as an assist for autopilot functions. Its use is not recommended in confined areas where flammable materials are present. Its design with a separable motor facilitates maintenance without depressurizing the entire hydraulic circuit, a practical advantage in the long term.

Frequently asked questions

Need help? Contact us

What is the Raymarine T2 12V reversible pump used for?

The Raymarine reversible T2 12V pump (part number M81121) 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 mechanically steered vessels in conjunction with a secondary steering cylinder.

What is the hydraulic cylinder capacity compatible with this Raymarine Type 2 pump?

The Raymarine Type 2 reversible pump is designed for medium to large steering systems, handling a cylinder capacity of 230 to 350 cc (14 to 21.4 cubic inches). For reference, the Type 0.5 handles 50-110 cc, the Type 1 handles 80-230 cc, and the Type 3 handles 350-500 cc.

What are the electrical specifications of the Raymarine T2 12V pump?

This pump is powered by a 12 V DC permanent magnet motor. It is designed to operate with a typical current draw of 24 A at 12 V and 55 bar pressure. All pump ports are 1/4 inch BSPP type.

Is the Raymarine T2 pump compatible with all types of hydraulic rams and systems?

Yes, the Raymarine T2 pump is compatible with balanced or unbalanced rams. It can also be used with pressurized reservoir systems. Its design includes pilot-operated check valves that prevent feedback from the manual steering system or rudder load.

Where and how to install the Raymarine T2 reversible pump?

The T2 pump is designed exclusively for installation below deck. For optimal performance and to avoid vibrations that could damage the pipes, it must be mounted on a solid structure. It is critical to install it away from heat sources, excessive vibrations, and fumes, and not to mount it in confined areas containing flammable materials. Additionally, it must be installed above the waterline. Absolute cleanliness is essential during the installation of hydraulic systems to prevent dirt particles from affecting the operation of the non-return valves.

Is the Raymarine T2 pump waterproof?

Yes, the Raymarine T2 reversible pump motor has an IP67 protection rating, making it water-resistant. This design allows you to remove the pump motor without introducing air into the hydraulic system or causing fluid leaks.
