Detailed description

Obratna hidravlična črpalka Raymarine T1 12V (M81120) je namenjena za pogon krmilnega mehanizma plovila v sistemu avtopilota Raymarine. Ta model je primarno namenjen čolnom, opremljenim z obstoječim hidravličnim krmilnim sistemom, ali pa se lahko uporablja z mehanskim krmilom v kombinaciji z sekundarnim cilindrom. Elektromotor 12V DC s trajnim magnetom ima klasifikacijo IP67, kar zagotavlja zaščito pred začasnim potopom in prahom, ter ga je mogoče odstraniti iz črpalke brez vdiranja zraka v hidravlični sistem ali povzročanja uhajanja tekočine.

Tehnične sposobnosti

Črpalka T1 (M81120) je združljiva s hidravličnimi cilindri enojnega ali dvojnega delovanja, ki pokrivajo kapaciteto od 80 do 230 cc. Dosega vršni pretok 1000 cc/min (brez obremenitve) in podpira največji prekinjen tlak 55 bar (800 psi) pri 12V. Tipična poraba toka je 19 A pri 12V in 55 bar. Vgrajeni pilotirani protitlačni ventili preprečujejo, da bi črpalka bila poganjana z ročnim krmilnim sistemom ali obremenitvijo krmila, kar zagotavlja stabilnost kursa. Ta model je tudi združljiv s sistemi s tlačnim rezervoarjem in je zaščiten za uporabo v motornih predelih.

Pozicija v Raymarineovi ponudbi

Obratna hidravlična črpalka Raymarine T1 12V (M81120) predstavlja vmesno rešitev v ponudbi hidravličnih črpalk Raymarine. Nudi večjo kapaciteto in pretok v primerjavi s črpalko Tip 0.5 (E12139), katere kapaciteta cilindra je 50-110 cc in pretok 600 cc/min. Vendar pa so modeli Tip 2 (M81121 12V, M81123 24V) in Tip 3 (M81122 12V, M81124 24V) namenjeni cilindrom z večjo kapaciteto, ki segajo od 230-350 cc za Tip 2 in 350-500 cc za Tip 3, z ustreznimi vršnimi pretoki 2300 cc/min in 3100 cc/min. Model T1 12V (M81120) predstavlja ravnotežje med zmogljivostjo in kompaktno zasnovo za širok spekter športnih čolnov. Vsi modeli Raymarine iz te serije delijo skupne značilnosti, kot so skladnost z normami CE 2004/108/EC (EMC) in 94/25/EC (RCD), ter zaščita IP67.

« Analysis of the Raymarine T1 12V hydraulic pump »

The Raymarine T1 12V hydraulic pump (M81120) is a fundamental component for autopilot systems on a wide range of recreational vessels, typically those equipped with mid-sized steering cylinders. Its capacity to handle cylinders from 80 to 230 cc makes it suitable for cruising sailboats or motorboats around 8 to 12 meters, where manoeuvring requirements demand more power than a 0.5 model but do not reach the needs of very large vessels. The 12V DC choice is standard and simplifies electrical integration on most boats.

Installing this pump requires absolute cleanliness of the hydraulic circuit to prevent contamination of the integrated check valves, which is critical for system reliability. Although the motor is rated IP67, it is recommended to install it in a dry, ventilated compartment, away from heat sources and excessive vibrations, to maximize its lifespan and the stability of hydraulic connections. This pump must be considered a secondary steering system drive, not a replacement for the primary system, in accordance with the manufacturer's safety directives.

Compared to Raymarine type 2 or 3 pumps, the T1 12V offers an optimal balance in size, power consumption, and delivered power, making it relevant for vessels whose cylinder does not justify the higher flow rate of higher-end models. For a successful installation, using high-quality hydraulic fittings and hoses is essential, along with thorough bleeding of the circuit after assembly.

Frequently asked questions

Need help? Contact us

What is the primary function of the Raymarine T1 reversible pump - 12V (M81120)?

The Raymarine T1 reversible pump - 12V (M81120) is designed to operate the steering mechanism of a vessel within a Raymarine autopilot system. It is primarily intended for boats equipped with an existing hydraulic steering system. It can also be used on a boat with mechanical steering in combination with a secondary ram.

Which types of hydraulic rams is the T1 pump (M81120) compatible with?

The Raymarine T1 pump (M81120) is compatible with single-acting or double-acting hydraulic rams. It is specifically designed for rams with a capacity between 80 and 230 cc (4.9 to 14.0 cubic inches).

What are the performance specifications of the T1 reversible pump - 12V?

The Raymarine T1 - 12V pump (M81120) delivers the following performance specifications at its nominal voltage:

Peak flow rate (no load): 1000 cc/minMaximum intermittent pressure (at 12 V): 55 bar (800 psi)Typical current draw (at 12 V and 55 bar): 19 A

Where and how should I mount the Raymarine T1 hydraulic pump?

The pump is designed exclusively for installations below deck. It must be mounted on a substantial structure to prevent vibrations that could damage the hoses. It must be installed away from heat sources, excessive vibrations, and fumes, and must never be placed in confined areas containing flammable materials. It is also recommended to install it above the waterline.

Is the T1 pump (M81120) protected against water and dust?

Yes, the Raymarine T1 pump (M81120) has an IP67 rating. This means it is protected against temporary immersion in water and against dust. The motor can be removed from the pump without introducing air into the hydraulic system or causing fluid leaks.

What are the EMC (Electromagnetic Compatibility) installation guidelines for the Raymarine T1 pump?

To ensure optimal electromagnetic compatibility (EMC) performance, Raymarine equipment and its cables should be:

At least 1 meter (3 feet) away from any equipment transmitting or cables carrying radio signals (e.g., VHF radios, cables, and antennas). For SSB radios, this distance must be increased to 2 meters (7 feet).More than 2 meters (7 feet) away from the path of a radar beam.Powered by a separate battery from the one used for engine starting to prevent erratic behavior and data loss.It is also recommended to use the cables specified by Raymarine and not to cut or extend them unless detailed in the installation manual.
