What Role Does Temperature Play in Hydraulic Hoses?

Hydraulic systems are vital to the operation of industrial equipment and heavy machinery.  They are integral from the manufacturing of parts to systems that power agricultural combines.  In any application, hydraulic hoses can fail due to selection of the wrong hose over pressurizing, improper installation of fittings and more.  Yet a commonly overlooked potential hazard is extreme temperatures.  Both high and low temperatures can a have significant effect on the efficiency, performance, and safety of a hydraulic system.

Hydraulic Hoses for Heavy Lifting and Handling Equipment

As with most critical applications, the correct choice of hydraulic hose for heavy lifting is vitally important. Whether it’s for system design or preventative maintenance, one must consider the temperature ranges, pressure ratings, bend diameter, and cover material.  Use support brackets where applicableto avoid unnecessary flexing and ensure the best hose position and avoid a bend that is tighter than the minimum radius allowed.  And use thermoplastic hoses for lightweight options, tighter than normal bend radiuses and wherever electricity may be present because a hydraulic hose with steel braids in it will have the high potential of conducting electricity.

Hydraulic System Trouble Shooting and Safety Precautions

Approximately 80% to 90% of all hydraulic equipment failures are caused by air or water contamination, or excessive heat.  Faulty pumps, temperature issues and system breaches (loss of fluid pressure most often caused by leaks or burst hydraulic hose) can each be a root cause of contamination.

Maintainable Hydraulic System Design: Redundant Systems

Safe system design and component placement in hydraulics are critical to maintainability and long service life. The proper location of components allows for easy access where they can be readily serviceable. And hydraulic systems are only as good as the components and fluid selection for the application.

Considerations for Proper Hydraulic Component Selection

Proper Component Selection

Ensuring hydraulic system components and their functions are leak-free begins with the design, which involves selection of the correct hydraulic fittings, hoses and other components for the application.  This could be a hose-end connection, hose or tube to port, a tube end or flange fitting.

Understanding Lockout & Tagout Safety Procedures

Lockout and Tagout Safety Procedures 

LOTO, or lockout and tagout procedures, is the most relied upon procedure for hydraulic maintenance safety.  According to OSHA, "Lockout/tagout refers to specific practices and procedures to safeguard employees from the unexpected energization or startup of machinery and equipment, or the release of hazardous energy during service or maintenance activities.

The Importance of Being Proactive With Corrective Hydraulic Maintenance

Corrective Maintenance
System components should be inspected during preventative hydraulic maintenance to address any anticipated issue before failure occurs.  Ideally the need for corrective maintenance can be identified and addressed during PM or in preparation for a scheduled or planned shutdown.  Be sure any repair of components is performed properly.  If not, issues may arise that can cause even greater harm.

Do You Have an Effective Preventative Maintenance Plan?

Preventative Maintenance

Preventative maintenance (PM) of a hydraulic system is a crucial function to maintaining the service life of equipment, reducing costs associated with unplanned equipment shutdown and the safety of personnel.

One the most important considerations in a PM plan is addressing stored hydraulic energy, such as a pressurized hydraulic reservoir.  Pressure must be released from the reservoir before replacing hydraulic fitting types, hose or any other maintenance procedure.

Keeping Safe Hydraulic System Maintenance Top of Mind

Hydraulic system maintenance is critical to the service life of equipment and the safety of personnel.  It is imperative that hydraulic maintenance technicians comply with necessary safety precautions.  This many involve crossing things off of a hydraulics maintenance checklist. They must have the necessary training and continuing education on the specific equipment and know how to properly take samples, use the right test equipment and record data that can be used for ongoing preventative and corrective maintenance.
