 Starting with the Basics

Hydraulic hoses consist of three main components: the inner tube, reinforcement, and outer cover. The inner tube carries the fluid, the reinforcement provides strength and withstands pressure, and the outer cover protects the reinforcement. This structure makes hoses quite similar to car tires.

A lay line is printed straight along the outer cover of the hose, serving two purposes: it provides essential information like product codes, ID, and working pressure, and it acts as a visual cue to indicate if the hose has been twisted during installation.

Temperature is a critical factor in hydraulic system design. When fluid flows under pressure, restrictions can generate heat, which can harm the hose assembly. Heat can also come from external sources, like an engine compartment. Consequently, some manufacturers produce hoses that can withstand higher temperatures or offer heat-resistant sleeving as an option.

 Hose Bend Radius

Automotive Lift Repair Tampa Florida Hoses come with various minimum bend radii, some more flexible than others. Hoses designed for high abrasion resistance may sacrifice some flexibility. Exceeding the bend radius can stress the reinforcement, especially on the outer curve, leading to bubbles under the outer cover.

Changes in hose length can occur under pressure, so it’s essential to allow extra length for this movement.

Ensure the hose assembly is designed to bend in only one plane to avoid twisting the wire reinforcement. Even a slight twist of 5% can reduce a hose’s lifespan by 60-70%, while a twist of 7-8% can lead to a reduction of up to 90%. If avoiding twists isn’t possible, consider changing the hose’s orientation or using a swivel coupling. If neither option is feasible, install a hose clamp between bends, allowing enough length on both sides to relieve stress on the reinforcement.

 Avoiding Abrasion

To prevent abrasion, use clamps to secure the Automotive Lift Repair Tampa Florida hose and avoid contact with surfaces or sharp edges. The clamps should fit snugly around the outer diameter (OD) of the hose, ensuring it doesn’t move but without damaging the cover. Leave enough slack on either side of the clamp to allow for expansion and contraction.

When bending in multiple planes is unavoidable, install a clamp between the bends.

Adding a protective sleeve to the hose assembly can enhance abrasion resistance. Common protective options include nylon sleeving, plastic spiral wrap, and heavy-gauge galvanized wire. Nylon sleeving is widely used where hose assemblies may be subject to damage. Plastic spiral wrap is an economical choice for wrapping individual hoses or bundling them together and can be applied after the ends are crimped. For harsh operating conditions, galvanized wire protection combined with a spring over the hose can help manage bending radius and reduce kinking.

Swivel joints (live swivels) can minimize flexing of the hose assembly caused by equipment movement.

An alternative option is to use a swivel fitting, also known as a live swivel. It’s crucial to distinguish between a swivel fitting that’s crimped onto a hose assembly, which can rotate under pressure but isn’t meant for continuous rotation, and a true live swivel.

 Keeping it Simple and Neat

Designing for a clean appearance in Automotive Lift Repair Tampa Florida hose routing not only prevents twisting and abrasion but can also lower maintenance costs by making assemblies easier to manage.

To maintain a neat look, opt for angled hose fittings instead of adapters, as each connection can be a potential leak point. Minimizing the number of adapters reduces additional components in the assembly. Crimped hose fittings and adapters are available in 45- and 90-degree angles.

In applications requiring angled fittings at both ends, consider the orientation between them. For example, a hose with two 90-degree fittings may need special alignment, sometimes referred to as “clocking.”

For systems with long runs of multiple hose assemblies, consider using hose carriers. Available in plastic and steel, these carriers link together like chains and protect hose assemblies from dirt, debris, and other environmental hazards.

 Introduction

The work truck industry often overlooks basic knowledge. In this article, we’ll explore different types of hydraulic hoses, clarify laylines, and explain what various hydraulic hose ratings mean.

The primary function of Automotive Lift Repair Tampa Florida hydraulic hoses is to facilitate the movement of hydraulic oil between two port locations in a hydraulic system. Additionally, they can absorb vibration and noise.

 Parts of a Hydraulic Hose

– Inner Tube: Typically flexible, this component allows fluid transfer.

– Reinforcement Layer: Comes in three types: braided, spiral, and helical (often used for suction/vacuum applications).

– Outer Layer: Designed to endure harsh weather, abrasions, and chemicals.

 Understanding Laylines

The layline printed along the length of the hydraulic hose contains important information, including the manufacturer/brand, hose series, construction standards, internal diameter, maximum working pressure, and any additional approvals.

 Pressure Ratings for Hydraulic Hoses

Automotive Lift Repair Tampa Florida Hydraulic hoses are classified based on the pressure they can handle during normal operation: low, medium, and high pressure. They can also be categorized by construction type, temperature range, and other performance factors.

– Low Pressure: Below 250 PSI, usually with textile/fabric braid reinforcement.

– Medium Pressure: Up to 3,000 PSI, typically featuring wire braid reinforcement.

– High Pressure: Ranges from 3,000 to 6,000 PSI, using a combination of wire braid and spiral braid reinforcement.

 Reinforcement Types for Automotive Lift Repair Tampa Florida Hydraulic Hoses

– Braided: Features a crisscross pattern for flexibility, allowing for tight bends while improving burst resistance. Braided hoses are the most common and suitable for medium to high-pressure applications, such as dump trucks and farm equipment. However, they are not ideal for high-impulse situations, like rock crushers.

 Inner Diameter Measurement

The inner diameter (I.D.) of hydraulic hoses is usually measured in inches, typically ranging from 1/4″ to 2″.

 Selecting the Best Automotive Lift Repair Tampa Florida Hydraulic Hose

The industry acronym STAMPED can help identify the best hydraulic hose for your needs:

– Size: Consider both the inner and outer diameters, along with the required length.

  – Questions: What are the I.D. and O.D.? What length is necessary?

– Temperature: Ensure the hose can withstand the maximum expected temperatures.

  – Questions: What are the fluid and surrounding temperatures?

– Application: Assess the environment and use case for the hose.

  – Questions: What type of application is it? Will the connection points be rotated or experience vibrations?
