Detailed description

Reverzibilna pumpa T2 - 24V (M81123) tvrtke Raymarine ključni je komponenta za sustave autopilota, namijenjena za upravljanje mehanizmom kormilarenja na brodovima opremljenima postojećim hidrauličkim sustavom. Također se može koristiti na brodovima s mehaničkim kormilarenjem putem sekundarnog kormilarskog cilindra. Ova pumpa ističe se mogućnošću integracije u različite konfiguracije, uključujući uravnotežene ili neuravnotežene cilindre te sustave s tlačnim spremnikom.

Konstrukcija i tehničke performanse

Pokreće je motor s trajnim magnetom od 24V DC, a T2 pumpa prikladna je za hidrauličke cilindre kapaciteta od 230 cc do 350 cc (14 do 21.4 in³). U okviru linije tvrtke Raymarine, ona se pozicionira kao rješenje srednje snage, iznad pumpe Tip 1 (80-230 cc) i ispod Tip 3 (350-500 cc). Isporučuje vršni protok od 2300 cc/min (140.4 in³/min) bez opterećenja i podnosi maksimalni intermitentni tlak od 55 bar (800 psi). Tipična potrošnja iznosi 11A pri 24V i 55 bar.

Motori imaju klasifikaciju IP67, što osigurava zaštitu u strojarnicama i otpornost na privremeno uranjanje. Njihova konstrukcija omogućuje uklanjanje motora bez unošenja zraka u hidraulički sustav ili curenja fluida. Ugrađeni su pilotirani povratni ventili koji sprječavaju protjecanje pumpe kroz ručni sustav kormilarenja ili opterećenje kormila, doprinoseći stabilnosti kormilarenja.

Integracija i sukladnost

Dimenzije pumpe T2 iznose 59.5 mm za dimenziju A i 204 mm za dimenziju B. Svi hidraulički priključci imaju format 1/4 inča BSPP (paralelni navoj). Ovaj proizvod udovoljava normama CE, uključujući 2004/108/EC (EMC) i EN60945:2002, kao i direktivi 94/25/EC (RCD), EN28846:1993 i EN ISO 10592:1995, što potvrđuje njegovu pouzdanost i elektromagnetsku kompatibilnost u pomorskom okruženju.

« Integration and performance of the Raymarine T2 24V pump for autopilots »

The Raymarine T2 reversible pump in 24V (M81123) is a targeted solution for autopilot systems on mid-sized vessels. Its 24V power supply makes it naturally suited for boats with an adapted electrical system, often cruising sailboats or larger motorboats compared to those equipped with 12V systems. It integrates at the heart of the autopilot system, particularly with SPX autopilot computers or Evolution actuator control units (ACUs).

During installation, absolute cleanliness of the hydraulic circuit must be ensured to prevent contamination of the check valves. Mounting below deck on a robust structure is mandatory to minimize vibrations and ensure the longevity of the fittings. The 230 to 350 cc cylinder capacity makes the T2 a relevant choice for medium-sized hydraulic cylinders, where a Type 1 pump would be underpowered and a Type 3 pump oversized, thus offering a balance between power and electrical consumption. It is crucial to ensure that the existing cylinder volume matches this range to guarantee optimal autopilot performance.

While installation can be performed by a knowledgeable user, Raymarine professional expertise is recommended due to the critical importance of the steering system for safety at sea. The quick-disconnect motors without hydraulic circuit bleeding simplify maintenance operations. This pump is not suitable for very low-volume steering systems (less than 230 cc) or very large cylinders (more than 350 cc), for which Type 0.5/1 or Type 3 models would be more appropriate.

Frequently Asked Questions

Need help? Contact us

What is the Raymarine T2 - 24V reversible pump used for?

The Raymarine T2 - 24V reversible pump is designed to function as an essential component of autopilot systems. Its primary function is to actuate the steering mechanism of a vessel. It is primarily intended for boats equipped with an existing hydraulic steering system. It can also be used on vessels with mechanical steering in conjunction with a secondary steering cylinder.

Which types of hydraulic rams is this pump compatible with?

This pump is compatible with hydraulic rams with a displacement ranging from 230 cc to 350 cc (14 to 21.4 in³). It can be used with balanced or unbalanced rams, whether single or double acting.

What is the required power supply for the Raymarine T2 pump - 24V?

The Raymarine T2 pump is powered by a 24V DC permanent magnet motor. Typical consumption is 11A at 24V under 55 bar pressure.

What are the physical dimensions of the reversible T2 pump?

The dimensions of the T2 pump are as follows:

Dimension A: 59.5 mmDimension B: 204 mmFor mounting, it has 4 holes for M6 bolts (0.25 in).

Where is the best place to install the hydraulic pump on my boat?

The pump must be installed below deck, on a solid structure to avoid vibrations that could damage the pipes. It is important to mount it away from heat sources, excessive vibrations, and fumes. Do not install it in confined areas containing flammable materials. It is also recommended to install it above the highest possible bilge water level.

What type of hydraulic connection does this pump use?

All hydraulic ports on the T2 reversible pump are in 1/4 inch BSPP format (parallel thread).

What are the flow rate and pressure performance specifications of the T2 pump?

The T2 pump delivers a peak flow rate of 2300 cc/min (140.4 in³/min) at no load. It can withstand a maximum intermittent pressure of 55 bar (800 psi).

Is the Raymarine T2 pump waterproof?

Yes, the T2 pump motors have an IP67 rating. This ensures protection in engine compartments and against temporary immersion. However, Raymarine does not guarantee products subjected to commercial high-pressure washing.
