Detailed description

Črpalka z dvojno smerjo T2 - 24V (M81123) od proizvajalca Raymarine je ključna sestavina za sisteme avtopilota, namenjena upravljanju krmilnega mehanizma na plovilih, opremljenih z obstoječim hidravličnim sistemom. Lahko se uporablja tudi na čolnih z mehanskim krmiljenjem preko sekundarnega krmilnega valja. Ta črpalka se odlikuje po tem, da se lahko vključi v različne konfiguracije, vključno z uravnoteženimi ali neuravnoteženimi valji in sistemi z rezervoarjem pod pritiskom.

Konstrukcija in tehnične lastnosti

Črpalka T2 je poganjana z motorjem s trajno magnetno polje 24V DC in je primerna za hidravlične valje z kapaciteto od 230 cc do 350 cc (14 do 21,4 in³). V seriji Raymarine predstavlja srednjo moč, nad črpalko Tip 1 (80-230 cc) in pod Tipom 3 (350-500 cc). Dosega vršni pretok 2300 cc/min (140,4 in³/min) brez obremenitve in vzdrži največji prekinjen tlak 55 bar (800 psi). Tipična poraba je 11A pri 24V in 55 bar.

Motorji so klasificirani z IP67, kar zagotavlja njihovo zaščito v motornih predelih in pred začasnim potopom. Konstrukcija omogoča odstranitev motorja brez vdora zraka v hidravlični sistem ali uhajanja tekočine. Vgrajeni so pilotirani protitlačni ventili, ki preprečujejo povratni tok črpalke skozi ročni krmilni sistem ali obremenitev krmila, kar prispeva k stabilnosti avtopilota.

Vključevanje in skladnost

Dimenzije črpalke T2 so 59,5 mm za dimenzijo A in 204 mm za dimenzijo B. Vsi hidravlični vhodi so v formatu 1/4 palca BSPP (paralelni navoj). Ta izdelek je v skladu z normami CE, vključno z 2004/108/EC (EMC) in EN60945:2002, ter direktivo 94/25/EC (RCD), EN28846:1993 in EN ISO 10592:1995, kar potrjuje njegovo zanesljivost in elektromagnetno združljivost v morskem okolju.

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

The Raymarine T2 reversible 24V pump (M81123) is a targeted solution for autopilot systems on mid-sized vessels. Its 24V power supply makes it a natural fit for boats with an appropriate 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 helm 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 essential to minimize vibrations and ensure the longevity of the fittings. The 230 to 350 cc cylinder capacity makes the T2 a relevant choice for mid-sized hydraulic cylinders, where a Type 1 pump would be underpowered and a Type 3 pump oversized, offering a balance between power and electrical consumption. It is critical to ensure 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 plug-and-play 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 serve as a key component in autopilot systems. Its primary function is to actuate the steering mechanism of a vessel. It is mainly 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.

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 current draw is 11A at 24V and 55 bar pressure.

What are the physical dimensions of the T2 reversible 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 hoses. 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 is used by this pump?

All hydraulic ports on the reversible T2 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 exposed to commercial high-pressure washing.
