As highlighted by Chart Attack’s recent publication, “Hydraulic Hose vs. Pneumatic Hose: Differences and Uses,” hoses are the unsung heroes of industrial and mechanical processes, facilitating the movement of fluids and gases in various applications. In this journey, we’ll delve into the world of hydraulic and pneumatic hoses, dissecting their essence, construction, and applications, while emphasizing the distinctions between them to assist you in selecting the ideal conduit for your specific needs.

Definition and Function

Imagine a pathway through which pressurized hydraulic fluid travels, powering a multitude of machinery – this is the fundamental role of a hydraulic hose. Engineered to transport hydraulic fluid among components, these hoses are the lifeblood of hydraulic systems, channeling the energy that drives everything from automobile brakes to heavy-duty machinery.

Beyond fluid transport, hydraulic hoses are integral to managing heat and maintaining optimal pressure levels. Their design is tailored to withstand high-pressure operations, and they are crafted from heat-resistant materials, making them indispensable in industries heavily reliant on hydraulic systems.

Construction and Materials

The construction of a hydraulic hose comprises several layers, each assigned a specific function. The innermost layer, known as the tube, is typically crafted from rubber or thermoplastic material, chosen for its chemical resistance and ability to contain hydraulic fluid. Encasing the tube is the reinforcement layer, often composed of braided or spiral-wound wire, imparting strength and flexibility to the hose.

The outermost layer, referred to as the cover, serves as protection against external elements such as abrasion, weather, and chemicals. Various types of rubber or thermoplastic materials are selected for the cover based on the hose’s intended operating environment. These layers collaborate seamlessly to confer distinct properties upon the hydraulic hose.

Malone Specialty: The Importance of Hydraulic Fluid Maintenance

As reported in the article “Why Maintenance of Water Glycol Hydraulic Fluids Makes All the Difference“, hydraulic fluids with hydrofluorocarbon or HFC technology have gained significant traction, boasting a market adoption rate of 50-55%. These water-based fluids find applications in industries where fire risks are prevalent. HFC hydraulic fluids are renowned for their exceptional fire-resistant properties and lubrication performance, making them the preferred choice for various sectors.

HFC technology, known for its low flammability, is a crucial asset in industries like high-pressure die casting (HPDC) foundries and steel-making shops. Besides their remarkable fire resistance, these fluids are favored for their OEM endorsements.

However, maintaining hydraulic systems that employ HFC technology is paramount to mitigate corrosion-related issues in system components. Neglecting maintenance can lead to substantial expenses associated with part replacements and unplanned downtime.

Effective maintenance entails routine sampling and analysis, safeguarding against costly component damage. A well-maintained HFC system exhibits remarkable reliability. In contrast, neglecting maintenance often results in unanticipated downtime, necessitating careful scheduling to minimize inconveniences and revenue losses. However, the long-term cost-efficiency and safety advantages of HFC become evident when accompanied by an efficient maintenance plan.

Four Key Maintenance Parameters:

  • Viscosity: The viscosity of a water glycol fluid is closely linked to its water content. As water is non-volatile, while glycol and PAG (polyalkylene glycol) thickeners remain in the hydraulic reservoir regardless of fluid temperature, viscosity tends to increase over time due to water evaporation. The rate of viscosity increase depends on factors such as ambient temperature, reservoir temperature, airflow across the reservoir breather, and the quantity of makeup fluid added. Hydraulic fluid suppliers often provide HFC users with viscosity-water content graphs, streamlining maintenance procedures. It’s important to note that water addition should be gradual.

Malone Specialty: Revolutionizing Hydraulic Systems for Heavy Commercial Vehicles

As reported by the Institution of Mechanical Engineers (IMechE) in their article titled “Hydraulic Systems Redesigned to Boost Efficiency of Heavy Commercial Vehicles,” the energy consumption of heavy commercial vehicles primarily occurs during lifting, carrying, or digging activities rather than during transportation. Unfortunately, the hydraulic systems responsible for these functions have often been outdated and inefficient.

In response to this challenge, the Advanced Propulsion Centre (APC) granted £10.9 million to the DDisplace project in 2018. The project’s aim is to revolutionize hydraulic systems, making them more efficient. Leading this initiative is Artemis Intelligent Power, a technology developer based in Edinburgh. They are collaborating with Danfoss Power Solutions, a Danish-American multinational, and hydraulic system specialist Robbie Fluid Engineering.

Alasdair Robertson, marketing director at Danfoss Power Solutions, highlighted a significant issue: “Hydraulic systems in a machine like an excavator have been shown to waste up to 70% of the energy that goes into them as heat. This inefficiency is a barrier to widespread electrification of off-highway machines and needs to be tackled urgently as part of the global road to net zero.”

The DDisplace project introduces a radical shift by adopting a radial configuration for its DDP096 Digital Displacement pump, replacing the traditional mechanically governed axial pump. This innovative design features pistons that are actuated by computer-controlled valves.

Robertson explained the potential benefits: “By replacing a conventional pump with a DD one, you can expect to save 10-20% of the input energy. For more complex implementations where we start to use the ability of the DD pump to have multiple independent outputs, we will leverage that to develop more advanced system architectures.”

Malone Specialty Inc.Purity in Motion: Insights on Mitigating Built-in Contamination in Hydraulics

The challenge of built-in contamination in hydraulic systems takes center stage in the article “Minimizing the Impact of Built-in Contamination in Hydraulic Systems,” featured on Machinery Lubrication. The adverse effects of contamination in hydraulic fluid power systems are well-known. The rationale is straightforward – reducing the gaps or clearances between moving parts enhances efficiency and allows for precise machine control. Particles compromise efficiency through abrasive wear and can disrupt machine control when they lodge in hydraulic valves.

The importance of addressing contamination-related issues, especially in hydraulic equipment assembly. Built-in contaminants introduced during the assembly of components contribute to increased warranty costs. Hydraulic equipment manufacturers adopt three primary strategies to mitigate the impact of such contamination.

The first strategy involves establishing contamination limits for new components. This decision entails a cost/benefit analysis, considering the trade-off between cleanliness and associated costs. Verification of component compliance with contamination limits is the second strategy, ensuring adherence to set standards. Lastly, flushing the assembled system to achieve a predetermined cleanliness target is the third approach, ensuring the roll-off cleanliness level.

The approach to contamination control should consider a hydraulic system’s contamination sensitivity and working pressure. By implementing these strategies, it supports industries in minimizing the impact of built-in contamination, thereby enhancing hydraulic system performance and reliability.
