MARINE HYDRAULICS – BESPOKE SOLUTIONS, FALMOUTH

This is dependent on the oil temperature, the application, work cycle and level of filtration installed within the hydraulic circuit. To discuss in further detail, please contact our specialist team.

The most common reasons for hose bursts are the wrong application, corrosion of the ferrules, high-pressure pulsing of the hydraulic installation, incorrect bend radius of the installed hose and out-of-date hoses. For more assistance and to discuss your hose requirements, please contact us.

Hydraulic temperature depends on oil type and viscosity. Use the oil manufacturer's data to determine expected heat. Consider ambient temperature, duty cycle and system design. Typically, 32-grade suits temperate climates; 46-grade suits are better for hotter conditions.

Before opening a hydraulic system, check if it's live, under pressure or affected by gravity. Isolate using valves or caps. For spills, use granules or pads. For supplies, contact our sales team on 01326 375566.

You must always refer to the original manufacturer's official information. However, most hydraulic systems will have a return filter that either has a visual clogging indicator or an electrical clogging indicator for your observation.

Check your operator's manual. Small yacht steering often uses 15-grade oil. Use 32-grade in temperate climates and 46-grade in tropical conditions. Some systems need flame-retardant synthetic oils, which are toxic, so always follow COSHH guidance.

As with all oils, protective clothing should be worn, and COSH information will be available from the oil supplier. To purchase protective clothing, visit www.armada24.co.uk or call our sales team on 01326 375566.

Stainless steel fittings resist corrosion and look good, but need anti-galling paste to prevent seizing. Steel-plated fittings corrode in marine use but are cheaper and practical for non-marine environments.

All your hydraulic component needs are catered for at www.armada24.co.uk, where we offer over 70,000 products combined with next-day delivery. If you prefer or need assistance with your order, you can contact our expert sales team on 01326 375566.

Yes. However, fireproofing of hoses is a complicated matter. We offer a range of MSHA-approved hoses, which are flame-resistant to US MSHA Approval IC-188. To cover the hydraulic range, please contact us for the full range and related data sheets.

Marked on all hydraulic hoses is the following information:

• Date of manufacture

• Manufacturer's name

• Working pressures

• DIN specification

In brief, the wire reinforcement integrated in the hose assembly denotes its strength relative to working pressure. The more wire reinforcement, the higher the pressure relative to the bore of the hose.

For example:

SAE100R2AT 2 wire 4SP Multispiral 4 wire

3/8” bore 330 bar wp 3/8” bore 460 bar wp

1⁄2” bore SAE100R2AT 275 bar wp 1⁄2” bore 440 bar wp

3⁄4” bore SAE100R2AT 215 bar wp 3⁄4” bore 380 bar wp

1" bore SAE100R2AT 165 bar wp 1" bore 320 bar wp

1 1/4” bore SAE100R2AT 125 bar wp 1 1/4” bore 240 bar wp

Please note that when selecting a hose, care must be taken as hydraulic systems can vary with the pulsing and spikes generated within the system. Professional advice should be sought.

Please contact us regarding the selection of hoses, as this is only a small sample of the products available to satisfy your requirements.

The basic components of any hydraulic system are as follows:

1. The prime mover (engine, electric motor, etc.)

2. Hydraulic pump pressure and flow

3. Control gear

4. Relief valve system pressure

5. Motor or cylinder, etc.

With any fault finding, if you break the system down into manageable areas as above, you can identify the location of the fault. To progress further, please contact us to discuss your exact requirements, and we will advise the correct way to proceed.

Basically, the pumps and motors available in the marketplace relate to a number of

• Design factors:

• Working pressures

• Applications

• Selection of hydraulic fluid

• Noise level

• Available horsepower

• Flexibility,i.e. hydraulic pressure and flow control, which includes electrical control.

• Cost

We offer a design and consultancy facility which offers full computer-aided design. Contact us for further information.

Firstly, you must consult the originator's equipment manual for starting procedures. However, we do not recommend any person without knowledge to start a system, as damage to the equipment, yourself and others may result. If you would like advice, we would be pleased to help. Just give us a call.
