Detailed description

Tvíhreyfispumpan T2 - 24V (M81123) frá Raymarine er lykilhluti fyrir sjálfstýringakerfi, hönnuð til að stjórna stýrisbúnaði á skipum með tilkomandi vökvakerfi. Hún getur einnig verið notuð á bátum með mekaníska stýrisbúnað með hjálparstýrisvél. Þessi pumpa getur verið sett upp í mismunandi uppsetningar, með jafnvægis- eða ójafnvægisvökvavélum og kerfum með þrýstihólf.

Hönnun og tæknilegir eiginleikar

Knúin með 24V DC rafsegulvél með fastmögnun, er T2-pumpan hönnuð fyrir vökvavélar með rúmmál frá 230 cc upp í 350 cc (14 til 21.4 tommur³). Á meðal Raymarine-vörum er hún millistærð, sem er öflugri en pumpan Type 1 (80-230 cc) en veikari en Type 3 (350-500 cc). Hún gefur af sér toppstraum 2300 cc/mín (140.4 tommur³/mín) við engri álagningu og þolir hámarksskammtaþrýsting 55 bar (800 psi). Venjuleg straumnotkun er 11A við 24V og 55 bar.

Rafsegulvélarnar eru með IP67-vörn, sem tryggir vernd í vélahólfum og gegn tímabundinni neðansjávarnotkun. Hönnun þeirra gerir kleift að fjarlægja vélar án þess að loft komist inn í vökvakerfið eða vökvi leki út. Stýrðar afturstreymisventilar eru innbyggðir til að koma í veg fyrir afturstreymi frá stýrikerfinu eða stýrihreyfingu, sem stuðlar að stöðugleika sjálfstýringar.

Uppsetning og samræmi

Mál pumpunnar T2 eru 59.5 mm fyrir mál A og 204 mm fyrir mál B. Öll vökvahol eru með 1/4 tommu BSPP-göng (jafnþræðing). Þessi vara er samrýmd við CE-viðmið, meðal annars 2004/108/EC (rafsegulþol) og EN60945:2002, ásamt stefnunni 94/25/EC (RCD), EN28846:1993 og EN ISO 10592:1995, sem staðfestir áreiðanleika og rafsegul-samhæfni í sjávarumhverfi.

« 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 a natural fit for boats with an adapted electrical network, often cruising sailboats or larger motorboats than 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 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 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. Plug-and-play motors with no 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 a key component in autopilot systems. Its primary role 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-acting 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 power draw 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 prevent 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 reversible T2 pump are in 1/4 inch BSPP format (parallel thread).

What are the flow rate and pressure performance 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.
