Detailed description

Dizajnirana za zahtjevne hidrauličke sustave kormila, Raymarine reverzibilna pumpa T3 24V (M81124) je rješenje namijenjeno brodovima opremljenim cilindrima kapaciteta od 350 do 500 cc. Ovaj model dio je serije hidrauličkih pumpi Raymarine i predstavlja najsnažniju opciju, iznad modela Tip 0.5 (50-110 cc), Tip 1 (80-230 cc) i Tip 2 (230-350 cc), nudeći tako kompatibilnost s većim brodovima. Može raditi s cilindrima jednostrukog ili dvostrukog djelovanja te se može integrirati u sustave s tlačnim spremnikom.

Performanse i tehnička integracija

Pumpa T3 24V napaja se istosmjernim motorom od 24 V, pružajući vršni protok od 3100 cc/min pri praznom hodu. Tipična potrošnja iznosi 15.5 A pri 24 V i tlaku od 55 bar, što ju čini učinkovitom za 24V električne sustave. Motori su certificirani IP67, omogućavajući ugradnju u strojarnice i osiguravajući zaštitu od privremenog uranjanja. Ugrađeni pilotirani nepovratni ventili sprječavaju povrat sile iz ručnog upravljanja ili opterećenja kormila, osiguravajući veću stabilnost i odgovornost autopilota.

Usklađenost i ugradnja

Ova pumpa usklađena je s normama EMC (EN60945:2002) i RCD (EN28846:1993 & EN ISO 10592:1995), što osigurava minimalizaciju elektromagnetskih smetnji. Ugradnja je namijenjena okruženjima ispod palube, zahtijevajući čvrstu montažnu strukturu za ograničavanje vibracija. Raymarine preporučuje uporabu specifičnih kabela i odvojene napajanje od baterije za pokretanje motora kako bi se optimirale performanse EMC. Apsolutna čistoća ključna je prilikom rukovanja hidrauličkim sustavima kako bi se osigurao ispravan rad nepovratnih ventila i spriječila kontaminacija hidrauličke tekućine. Hidraulički priključci su u formatu 1/4 inča 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 between 350 and 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 rudders, 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 load on the vessel’s electrical system and 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 done below deck on a rigid structure to prevent excessive vibration that could compromise hydraulic fittings. Extreme cleanliness is required during hydraulic connections; even a tiny particle can disrupt the operation of the check valves. While the unit is rated IP67, protecting it from direct spray and areas of high condensation is still advisable to maximize its service life. 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 equipped with cylinders with a capacity between 350 cc and 500 cc (21 to 30.5 cubic inches). It is compatible with single 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 with a 24 V DC power supply.

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

The pump is designed for installation below deck only. It is critical 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 under no-load conditions.

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

For optimal EMC performance, it is recommended to use the cables specified by Raymarine and to 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.
