Detailed description

Skirta reikliems hidraulinio vairo sistemų poreikiams, Raymarine reversinis siurblys T3 24V (M81124) yra sprendimas laivams, įrengtiems su cilindrais, kurių talpa nuo 350 iki 500 cm³. Šis modelis priklauso Raymarine hidraulinio siurblių serijai ir yra galingiausias variantas, pralenkiantis Type 0.5 (50-110 cm³), Type 1 (80-230 cm³) ir Type 2 (230-350 cm³) modelius, todėl tinka didesnėms valtim. Jis gali veikti su vieno ar dvigubo veikimo cilindrais ir integruojamas į sistemas su slėginiu rezervuaru.

Techninės charakteristikos ir našumas

Siurblys T3 24V maitinamas nuolatinės srovės 24 V varikliu, kuris be apkrovos pasiekia 3100 cm³/min srauto debitą. Tipinė srovė – 15,5 A esant 24 V ir 55 bar slėgiui, todėl jis efektyvus 24 V elektrinėms sistemoms. Varikliai atitinka IP67 apsaugos standartą, leidžiantį įrengti juos variklių skyriuose ir užtikrinantį apsaugą nuo laikinos panirimo. Įmontuoti valdomi grįžtamieji vožtuvai neleidžia grįžti jėgai iš rankinio vairo arba vairo apkrovos, užtikrindami autopiloto stabilumą ir reaguojamumą.

Atitikties normos ir montavimas

Siurblys atitinka EMC (EN60945:2002) ir RCD (EN28846:1993 & EN ISO 10592:1995) normas, garantuojančias elektromagnetinių trikdžių minimizavimą. Montavimas skirtas laivo apačioje esančiose erdvėse, todėl rekomenduojama naudoti tvirtą montavimo konstrukciją, siekiant sumažinti vibracijas. Raymarine rekomenduoja naudoti specialius kabelius ir atskirą maitinimo šaltinį nuo variklio starterio baterijos, kad optimizuoti EMC charakteristikas. Absoliučiai švarus darbo procesas yra būtinas hidraulinėms sistemoms, siekiant užtikrinti grįžtamųjų vožtuvų veikimą ir išvengti hidraulinio skysčio užteršimo. Hidrauliniai jungtys yra 1/4 colio BSPP formato.

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

The Raymarine T3 reversible 24V hydraulic pump (M81124) is specifically sized for autopilot applications on medium to large vessels where the hydraulic ram 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 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 strain 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 forced by the manual steering system or rudder pressure, which is essential for system longevity and safety.

Installation must be done below deck on a sturdy structure to prevent excessive vibrations that could compromise hydraulic fittings. 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 heavy condensation is still preferable to maximize its lifespan. This model is a sound choice for boats requiring a reliable, high-power autopilot capable of handling large hydraulic rams 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 having a displacement 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 on 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 vibration, or fumes, and do not install it in confined spaces containing flammable materials.

What are the benefits of the integrated 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 helps ensure greater 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 secure 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, it is recommended to use the cables specified by Raymarine and to provide a power supply separate 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.
