Detailed description

Namenjena zahtevnim hidravličnim sistemom krmiljenja, je črpalka Raymarine T3 24V (M81124) rešitev za plovila opremljena z cilindri z zmogljivostjo 350 do 500 cc. Ta model spada v serijo hidravličnih črpalk Raymarine in je najmočnejša možnost nad modeloma Type 0.5 (50-110 cc), Type 1 (80-230 cc) in Type 2 (230-350 cc), kar omogoča kompatibilnost z večjimi plovili. Zmožna je delovati na enojno ali dvojno delujoče cilindre in jo je mogoče integrirati v sisteme z tlačnim rezervoarjem.

Zmogljivost in tehnična integracija

Črpalka T3 24V je poganjana z enosmernim motorjem 24 V, ki dosega vršni pretok 3100 cc/min v praznem teku. Tipična poraba je 15,5 A pri 24 V in 55 bar, kar jo naredi učinkovito za sisteme 24V. Motorji so certificirani IP67, kar omogoča namestitev v motorne prostore in zagotavlja zaščito pred začasnim potopitvijo. Vgrajeni so pilotirani protitlačni ventili, ki preprečujejo vračanje sile iz ročnega krmilnega sistema ali obremenitve krmila, kar zagotavlja stabilnost in odzivnost avtopilota.

Usklajenost in namestitev

Ta črpalka je v skladu z normami EMC (EN60945:2002) in RCD (EN28846:1993 & EN ISO 10592:1995), kar zagotavlja minimalno elektromagnetno interferenco. Namestitev je namenjena okoljem pod palubo, ki zahtevajo trdno montažno strukturo za omejevanje vibracij. Raymarine priporoča uporabo specifičnih kablov in ločene napajanja iz baterije za zagotavljanje optimalnih EMC zmogljivosti. Absolutna čistota je bistvena pri rokovanju z hidravličnimi sistemi, da se zagotovi pravilno delovanje protitlačnih ventilov in prepreči kontaminacija hidravlične tekočine. Hidravlični vhodi so v formatu 1/4 palca BSPP.

« Technical analysis: Raymarine T3 24V pump for large hydraulic systems »

The Raymarine T3 24V reversible hydraulic pump (M81124) is specifically sized for autopilot applications on medium to large vessels, where the hydraulic cylinder capacity ranges from 350 to 500 cc. Unlike the T0.5, T1, or T2 models, this pump delivers the power and flow rate (3100 cc/min) required to operate larger rudder surfaces, ensuring adequate autopilot responsiveness.

Its 24V power supply is a major advantage for installations where a 24V electrical system is already in place, reducing current draw (15.5 A at 55 bar) compared to an equivalent 12V version (34 A for model M81122). This minimizes the load on the vessel’s electrical system and the required cable cross-section. The inclusion of pilot-operated check valves is a critical feature, ensuring the pump is not back-driven by the manual steering system or rudder pressure, which is essential for system longevity and safety.

Installation must be performed below deck on a sturdy structure to avoid excessive vibrations that could compromise hydraulic connections. Extreme cleanliness is required during hydraulic connections; even a minute particle can affect the operation of the check valves. While the unit is rated IP67, installation in a location protected from direct spray and areas of high condensation is always preferable to maximize its lifespan. This model is a sound choice for boats requiring a reliable, high-power autopilot capable of handling large hydraulic cylinders without overloading a 12V electrical system.

Frequently asked questions

Need help? Contact us

What is the hydraulic cylinder capacity compatible with the Raymarine T3 24V pump?

The Raymarine T3 24V pump (M81124) is designed for hydraulic steering systems fitted with cylinders having a displacement between 350 cc and 500 cc (21 to 30.5 cubic inches). It is compatible with single-acting or double-acting cylinders.

What is the required supply voltage for this Raymarine T3 pump?

The Raymarine T3 reversible pump (M81124) is specifically designed to operate on a 24 V DC power supply.

Where and how should I install the Raymarine T3 hydraulic pump on my boat?

The pump is designed for installation below deck only. It is crucial to mount it on a substantial structure to minimize vibrations that could damage the hoses. Avoid mounting it near heat sources, excessive vibrations, or fumes, and do not install it in confined areas containing flammable materials.

What are the benefits of the built-in check valves in this pump?

The Raymarine T3 pump integrates pilot-operated check valves. These valves prevent the pump from being driven in reverse by the manual steering system or by the rudder load. This contributes to improved stability and responsiveness of the autopilot.

Is the Raymarine T3 pump water-resistant?

Yes, the Raymarine T3 24V pump motor is IP67 certified. This rating ensures protection against temporary immersion and allows safe installation in engine compartments.

What is the maximum flow rate of this hydraulic pump?

The Raymarine T3 24V pump (M81124) delivers a peak flow rate of 3100 cc/min (189.2 cubic inches per minute) when operating at idle.

How can I optimize electromagnetic performance (EMC) when installing the pump?

For optimal EMC performance, use the cables specified by Raymarine and provide a separate power supply from the engine starter battery. Additionally, Raymarine equipment and cables must be kept at least 1 meter away from equipment transmitting radio signals (such as VHF radios) and more than 2 meters from the path of a radar beam.

What types of hydraulic fittings are used on the Raymarine T3 pump?

All hydraulic ports on the Raymarine T3 pump are 1/4 inch BSPP (parallel thread). Rubber/metal seals are supplied with the pump, and 1/4 inch BSP to 1/4 inch NPT adapters may be required depending on your existing hydraulic system.
