HYDRAULICS & PNEUMATICS
IMPROVE YOUR TROUBLESHOOTING
Would you know what to do if your pneumatic system was experiencing intermittent pressure fluctuations? Are you confident that the component you have just replaced was actually the cause of the fault? How can you extend mean time between failure to optimise productivity?
LSRV LIMITS PRESSURE
Power management company Eaton has introduced a sectional load sense relief valve (LSRV) for its CLS mobile hydraulic control valve. The patented LSRV limits individual section pressure through feed oil reduction, eliminating the need for inefficient work port reliefs for feed-side pressure control. The CLS LSRV improves machine productivity and efficiency by helping prevent functions from slowing down during multi-section actuation and by eliminating unnecessary energy consumption and heat generation.
“Most load sensing mobile valves make you choose between power management and pressure control,” said Jiri Foukner, EMEA product manager, Advanced Mobile Valves, Eaton. “Eaton’s CLS valve eliminates this trade-off. With the new sectional LSRV, the CLS
valve combines the benefits of pre-compensated and post- compensated valves, providing pressure control while maintaining flow sharing and power management capabilities.”
The CLS LSRV enables the use of full available inlet flow to maintain functionality during multi-section actuation, helping improve machine productivity. The LSRV limits pressure by reducing feed oil flow, rather than dumping the flow to the tank. Once the LSRV stops oil flow when a function reaches a specific pressure, which can be lower than maximum system pressure, that flow is available to other sections at full system pressure. This helps prevent machine functions from slowing down when multiple sections are operating at once. Eaton

During the course of everyday operations, hydraulic hose assemblies, and other hoses, are exposed to moisture, dirt, cuts, abrasions, crushing and UV rays. Continuous movement and rubbing against other hoses or equipment - often caused by machine vibrations - can erode hoses, while non- compatible fluids can eat away
According to Festo, these are common dilemmas faced by engineers with responsibility for pneumatic systems in industries across the UK. From pharmaceuticals to machine tooling, electronics assembly to food production and packaging, pneumatic systems play a fundamental role in performing highly repetitive tasks. Understanding how pneumatic systems work and being able to diagnose and correct faults effectively are therefore vital engineering skills. Drawing on its experiences as a manufacturer and employer, Festo has been running training courses for many years that take engineers through the fundamentals of pneumatic system design and operation. It has recently added a new course, available from July 2021, that focuses on troubleshooting and fault diagnosis to further improve skill levels in the pneumatic systems arena.
Hakan Emince, head trainer for Festo Didactic, explains: “The performance of pneumatic systems in industry directly impacts overall equipment effectiveness, productivity and competitiveness. Our new course, Troubleshooting and Maintenance in Pneumatics, offers an introduction to common mistakes, fault finding, maintenance and inefficiency in pneumatics and electro-pneumatics systems. Using a combination of theory and practical exercises, the course aims to improve how engineers approach maintenance of pneumatic systems and enable them to deal with breakdowns more efficiently.” The practical sessions are used to simulate various common problems, helping delegates to understand reasons and consequences of issues from real life. Among other things, participants will learn how to interpret pneumatic system diagrams, how to establish the root cause of a problem quickly, fix faults faster, and avoid costly downtime; and how to optimise system performance to improve the quality, efficiency and lifecycle of the machine. Aspects such as hazard identification and safety are also covered. Troubleshooting and Maintenance in Pneumatics is a two-day course and is applicable for personnel in multiple engineering type roles, who already have a grasp of pneumatic system fundamentals. Courses take place at Festo’s dedicated purpose-built training centre in Northampton, although there is an option to run courses at the customer’s site for groups where circumstances allow. If potential attendees are unsure if they are at the correct level for the course then they can complete a free knowledge check via the Festo Didactic website.

Hose protection products from Essentra Components address these issues in the many ways described in this new guide, which includes information on use, installation and specifications for protecting against hose bursts or leakage, mining safety approval, and fire protection sleeves.
