Servicing Hydraulic Systems for Harbour Authority

At Rotec Hydraulics, we believe that a well-maintained hydraulic system is the backbone of efficient and reliable operations. We recently carried out essential hydraulic power unit (HPU) servicing for a returning customer – a major harbour authority in Devon.

Our experienced engineers carried out a thorough service of the client’s HPU, including:

  • HPU Draining & Oil Replacement: We began by draining the old hydraulic oil from the HPU, preparing the system for a fresh start.
  • Critical Hose Replacements: The project required the replacement of two steering system “severe rated” hydraulic hose assemblies. Our engineers manufactured new hoses, making them 150mm longer to allow for better routing around a tie-rod. This small modification significantly reduces wear and tear and extends the life of the hoses. We also identified and replaced two additional hose assemblies with damaged outer sleeving, preventing potential future failures.
  • Component Inspection & Servicing: We removed and inspected the slow stow adjuster and its associated solenoid. This step involved servicing, cleaning, and replacing seals as needed, ensuring these components operate flawlessly.
  • System Flushing & Filtration: To guarantee a clean system, we installed a temporary hydraulic filter in the Man Overboard (MOB) system. We then refilled the tank with BIO ISO-32 oil and ran the system through, directing the flow of oil through the pressure filter to effectively flush out any contaminants.
  • Final Commissioning: After the flushing process, we reinstated the system, carefully bled the lines, and performed a comprehensive commissioning to ensure everything was functioning correctly. We also performed fault-finding on the MOB system, addressing any issues proactively.
  • Site Clean-up: We believe a job isn’t complete until the site is left clean and tidy, a final touch that underscores our professionalism and respect for our client’s workspace.

Preventative Maintenance for Hydraulic Pumps to Boost Efficiency and Reduce Downtime

At Rotec Hydraulics, a Parker Certified Hydraulic Technology Centre with over 45 years of experience, we advocate businesses to adopt a proactive approach to hydraulic pump maintenance.

Preventative care is far more cost-effective than reactive repairs, which is why we offer flexible preventative maintenance service contracts to help clients avoid costly and unexpected system failures.

Proactive Hydraulic Pump Maintenance

Hydraulic pumps are at the heart of hydraulic systems. However, without regular maintenance, their performance can quickly degrade, leading to inefficiency, increased energy consumption, and catastrophic failures.

Routine maintenance and inspection are crucial because:

  • They prevent expensive breakdowns: A small, easily fixed issue, like a worn seal or contaminated fluid, can escalate into a complete pump failure, requiring a full and costly replacement.

  • They extend equipment life: Regular servicing and timely replacement of components—such as seals, bearings, and filters—significantly extend the operational life of the pump.

  • They improve efficiency: Clean, well-maintained pumps operate at peak performance, reducing energy waste and ensuring the system performs as designed.

A thorough strip-down and inspection is recommended every 2,000 to 4,000 operating hours or as indicated by the manufacturer. This may also be reduced if operating in a particularly harsh environment. Rotec’s in-depth service allows technicians to identify internal wear and tear that isn’t visible during routine checks.

Managing Hydraulic Systems in High-Temperature Environments

High temperatures pose a significant threat to the performance and longevity of hydraulic systems. Elevated heat can lead to a rapid decline in fluid quality, premature component wear, and potential system failure. We’ve summarised some proactive maintenance measures you can take to mitigate these risks and maintain operational reliability.

Fluid Temperature Monitoring

Regularly monitoring hydraulic fluid temperature is critical. The ideal operating range for most systems is 40°C to 60°C (104°F to 140°F). Temperatures exceeding this range accelerate fluid degradation. Systems should be equipped with a reliable temperature gauge to provide accurate and continuous readings. A significant increase in temperature from a known baseline indicates a potential issue requiring immediate attention.

Hydraulic Fluid Selection and Management

The viscosity of hydraulic fluid is directly affected by temperature. As the temperature rises, viscosity decreases, reducing the fluid’s ability to lubricate components effectively.

  • Adherence to specifications: Always use the hydraulic fluid recommended by the manufacturer. This fluid is designed to maintain optimal performance within the specified operating parameters.
  • Viscosity Index: In consistently hot environments, a fluid with a higher viscosity index (VI) may be considered, but only after consultation with a hydraulics expert or the equipment manufacturer. A higher VI indicates less change in viscosity with temperature fluctuations.
  • Fluid levels: Maintain correct fluid levels to prevent cavitation, which occurs when air bubbles form and collapse, causing damage to pumps and other components.

Cooling System Maintenance

The hydraulic cooler is vital for dissipating heat. Its efficiency is paramount in high-temperature conditions.

  • Regular cleaning: The cooler’s fins must be kept free of debris, such as dust, dirt, and leaves, which can restrict airflow. Use compressed air or a soft brush to clean the surface regularly.
  • Inspection: Inspect the cooler for any damage, such as bent fins, that could impede heat exchange.
  • Fan operation: For forced-air coolers, verify that the fan is operating correctly and is free from any obstructions or electrical faults.

Operational Practices

Operational practices can significantly influence a system’s thermal load.

  • Duty cycles: Avoid continuous, high-load operation during the hottest periods of the day. Scheduling demanding tasks for cooler hours can reduce thermal stress on the system.
  • Load management: Where possible, reduce the load on the equipment to decrease the amount of heat generated.

Component Integrity Checks

High temperatures can degrade seals and hoses, leading to leaks and component failure.

  • Leak inspection: Regularly inspect all hoses, seals, and connections for signs of leaks. Heat can cause materials to harden and crack, compromising their integrity.
  • Physical inspection: Check hoses and seals for signs of blistering, cracking, or other physical deterioration.
  • Connection integrity: Ensure all connections are properly tightened to prevent leaks caused by vibration and thermal expansion.

By implementing these preventative maintenance measures, system operators can ensure the long-term health and efficiency of their hydraulic equipment, even under the stress of high-temperature conditions.

Two HPUs and Ten Jacking Cylinders Manufactured for New Client

Earlier this month, Rotec Hydraulics completed a large project for a new customer who specialises in all aspects of confined space working from sewer rehabilitation, timber headings, tunnelling, grouting, all types of shaft sinking and associated clean and waste water works.

With a wealth of experience constructing shafts up to 30 metres in diameter and to depths of 35 metres, the specialist construction company sink shafts using various techniques – including hydraulically jacking segmental shafts vertically.

Rotec were asked to design, build and deliver ten hydraulic cylinders and two hydraulic power units (HPUs) capable of powering 40 tonne hydraulic jacks with up to 210 bar pressure for a significant shaft sinking project.

The HPUs operate ten hydraulic jacking cylinders using ten off detented levels and a single sprung loaded dead man’s lever. The jacking cylinders have a 160 bore, 110 rod, 1200 stroke and are mounted in frames which push down concrete segments to line holes. Each cylinder can provide up to 40 tonne force with 210 bar pressure which can be controlled by an adjustable knob on the HPU.

To speed up the extension and retraction of the cylinders, the HPUs have been designed with a two-stage pump which produces a faster flow when less hydraulic pressure is required. The pump is powered by a 7.5 kW 3-phase electric motor which is controlled by electrics mounted in an enclosure on each HPU. This allows the pump to be started and stopped easily, as well as providing essential emergency stop buttons.

Both HPUs have a 500 litre tank with pressure and return filters, in addition to a fitted level/temperature gauge. Connections from the HPUs to the cylinders are via protected hoses with quick release connectors.

To increase safety and reduce risk of harm to the operator, the hydraulic hoses on both the HPU and those to the hydraulic cylinders have been fitted with hose burst protection and whip checks where necessary.
