Trelleborg Showcases Fluid Power Capabilities 

Trelleborg Sealing Solutions will showcase their complete range of sealing solutions for fluid power applications next month at the Fluid Power & Systems exhibition in Birmingham. A new “best in class” seal for hydraulic cylinders with the ability to thrive in unforgiving conditions will be highlighted, as well as a design study on ‘Lubrication Management’.

The Zurcon® Glyd Ring® D piston seal has “leapfrogged” competitors thanks to its combination of performance and service life through optimized contact pressure and minimized heat generated from friction. The innovative design incorporates two special grooves in the D-shaped profile of the seal to sustain an oil film for sufficient lubrication of the seal against its counter surface, ensuring adequate friction.

The compact seal, which has been subjected to extensive laboratory testing and long-term field testing, was developed in response to increasing demands from high-pressure hydraulic applications. Machines, equipment and motors are now being fitted with more powerful hydraulic cylinders, subjecting the hydraulics to higher pressures and temperatures.

The seal is manufactured from Zurcon® Z13 polyurethane (PU) material, specially developed to cope with pressures of up to 500 bar/ 7,250 psi at both sides of the seal and at temperatures up to +120 °C / +248 °F. This lengthens the seal’s life, even under demanding conditions, offering superb mechanical and elastic properties.

Andrew Longdon, UK Technical Manager at Trelleborg Sealing Solutions, said: “We have made subtle but significant changes to our previous Glyd Ring® compact double-acting piston seal, leading to a new and improved best-in-class seal for hydraulic cylinders with the ability to thrive in unforgiving conditions.

“In the latest more powerful hydraulic applications, high pressure is combined with elevated temperatures. Our new Zurcon® Z13 PU material used in Zurcon® Glyd Ring® D is specially developed to cope with this combination. We can now offer a seal for hydraulic cylinders that has a long life – leapfrogging the competition.”

The pioneering seal was a joint development between Trelleborg’s research and development centre in Stuttgart, Germany, and their Polyurethane Centre of Excellence in Livorno, Italy.

Core industrial applications for Zurcon® Z13 Glyd Ring® D include construction machinery, earthmoving equipment, mobile cranes, forklift trucks and any other solutions involving mobile hydraulics. The seal offers superior resilience and good friction properties. It is compatible with hydraulic, mineral, synthetic and water-based fluids and with a hardness of 60 shore D offers outstanding wear resistance, excellent extrusion properties and hydrolysis resistance.

Meanwhile, Trelleborg Sealing Solutions has developed a whitepaper, film, webinar and brochure to showcase its work in Lubrication Management Technology, which is helping to revolutionize hydraulic sealing.

The technology is transforming hydraulic sealing by adjusting lubrication conditions of all single sealing elements within a sealing system, which in turn, optimizes the performance of the hydraulic system in terms of friction, wear and lifetime.

Trelleborg Sealing Solutions will be exhibiting on stand AF1350 at Fluid Power & System 2018, which takes place at the NEC in Birmingham from April 10 to 12.

How to Decide Between Electric, Pneumatic and Hydraulic Actuators 

Fluid power is a well-established technology; but in case you haven’t noticed, electric actuators have come a long way in the past ten years. But does that mean that fluid power systems are obsolete?

To answer that question, I spoke to experts from automation suppliers Festo and SMAC. Festo carries both electric and pneumatic technology, while SMAC specializes in a variety of types of electric actuators from ball screw-driven devices to linear motors.

According to Jim Ackert, applications specialist at Festo, fluid power systems may not be going anywhere. In many applications where they were once ubiquitous, however, electrics are pushing in.

“For the time being, I think all three technologies have their place in industry,” said Ackert. “But, the flexibility of electric drives, coupled with the fact that the price of electric components has been steadily coming down over the years, makes them more popular and affordable than they once were.”

Tradeoffs Between Electric, Pneumatic and Hydraulic Actuators

It may sound frivolous, but choosing the right actuator technology is a lot like choosing a role-playing game character: the Fighter, Mage and Thief are classic character archetypes in video games, with trade-offs in damage, health and speed. When it comes to actuators, the trade-offs are force, positioning accuracy and speed.

In general, the overlap between the force and speed capabilities of fluid and electric actuators is growing. Electric actuators are even making their way into heavy equipment presses and other traditionally hydraulic-dominated markets.

Refresher on Use and Care of Hydraulic Breaker Attachments

Designed to demolish rock, concrete and intact construction materials, hydraulic breakers can be a best friend on a jobsite where demolition is the end goal. Using proper operating techniques, pulverizing rock and breaking apart concrete can be accomplished efficiently and effectively. However, improper operation can just as easily derail a project, costing valuable time if a breaker fails unexpectedly on the job, or costing money by potentially increasing maintenance and/or shortening attachment life.

To ensure a long, productive life for your breakers, make sure operators are adequately trained and follow these recommended operating tips.

Don’t Dwell Too Long in One Place

In an attempt to finish a job quickly and break material all at once, some operators may start at the center of a rock or large piece of concrete. “But it’s better to work from an edge,” says Rob Sherwin, president, Arrowhead Rockdrill. “When you go straight to the center of the work, you can damage the working tool or wear it out prematurely. If it’s a rock breaking application, look for a natural crack to aid in the process.”

Hammering continuously in one place for more than 30 seconds is also counterproductive and can damage the breaker.

How Many Times Can I Reassemble a Hydraulic Fitting?

Wouldn’t it be great if leak-free connections could last forever? Great, yes. Realistic, no. The good news is that fitting designs have improved significantly over time, making it easier to assemble and reassemble most connections and conduct routine maintenance without increasing the risk of leak paths.

Two common types of fittings, however, generally rank poor for reusability. When dealing with tapered-thread pipe and JIC (Joint Industry Council) or 37° flare fittings, in particular, anyone doing maintenance on a fluid system should always ask: “Can I reassemble this fitting, or does it need to be replaced?”

Tapered-Thread Pipe Fittings

These torque-sensitive fittings have been around for many years, and if you’re working on old equipment, you’re likely to come across tapered-thread pipe fittings. They use a thread interface to make a metal-to-metal seal that generally is supplemented with the use of a sealant, such as tape or paste. Repeated assembly and disassembly can distort the threads, so it’s important to thoroughly inspect the threads for damage before reusing one of these fittings.

It would be wise to replace the male fitting any time you disassemble a tapered-thread fitting. But if you’re being frugal and want to reuse a fitting, here’s a quick way to determine if your reconnection will be leak-free:

LiuGong revamps its 856H hydraulic wheel loader

The new LiuGong 856H hydraulic wheel loader has been redesigned specifically for the North American market.

Powered by a 225 hp, EPA Tier 4 Final Cummins engine, the LiuGong 856H promises high productivity through advanced technology, including a powershift transmission and advanced load-sensing hydraulic system. The company showcased the machine at World of Asphalt 2018 in Houston, Texas.

“It’s completely redesigned. It has an increase in rated payload, and a new and improved cab,” said Hugo Chang, wheel loader product manager for LiuGong North America.

The wheel loader is equipped with LiuGong’s advanced load sensing hydraulic system. The technology matches hydraulic flow with the operator and ensures the mechanical, electrical and hydraulic systems work in harmony. Power is supplied only when it is needed to optimize efficiency.

“The new Tier 4 final hydraulics is a closed centre system with a piston pump swash plate for controlling simultaneous lift and curl functions,” Chang said. “The operator can, with the appropriate use of the joystick, attain simultaneous lift and curl functions which was not possible on our previous Tier 3 product line.”

LiuGong also totally redesigned the cooling system to lower fuel consumption. The airflow from the radiator to the fan, combined with the new hexagon grill, improves ventilation. As well, the variable hydraulic fan drive minimizes power needs, and operators have the ability to reverse airflow to increase radiator cleanout intervals.

“It now allows for the cooling system to react at the speed that is required by the machine, based on its usage and ambient temperature,” Chang said. “This equals lower fuel consumption and lower overall machine noise.”

To further decrease fuel consumption, the wheel loader includes auto-idle speed function, which allocates the appropriate rpm for the task at hand. If activity isn’t detected for 10 minutes, the auto-idle speed function will automatically reduce engine speed to idle. The engine immediately returns to the current throttle setting when commanded work is detected.

The 856H also integrates ZF Powershift transmissions, which are available in two types of 4F/3R. As well, the torque converter is optimized for maximum transfer of power to the transmission.

The kick-down button, located on the loader’s joystick, allows the operator to gear down with the tip of a finger to increase torque generated by the engine to boost breakout force and loading capability.

Variable-Speed Hydraulic Pump Drives Save Energy, Cut Noise and Heat 

The use of variable-speed hydraulic pumps has grown with the development of high-speed controls, quick-response motors, and improved software that give these motor-pump combinations the power and responsiveness to match systems controlled by electrohydraulic valves or a variable-displacement pump, while also reducing energy consumption.

Traditionally, constant-speed ac induction motors have been used to drive the pumps in stationary hydraulic systems, with hydraulic power controlled by flow- and pressure-regulating valves or a variable-displacement pump. However, the constantly-running motor can consume as much as 50% of full-load current, even when the system is not under load. In addition, pumps and motors in conventional hydraulic power units (HPUs) often are oversized to meet maximum duty-cycle demands. By contrast, a variable-frequency drive or servodrive can manage an electric motor’s operating torque and speed more efficiently. Instead of running continuously at full speed, the motor rotates only fast enough to meet system demand at any given time.

A hydraulic system with a variable-speed drive combines the robust, power-dense benefits of hydraulics with the intelligence and ease of integration into automation systems provided by electric drives. Energy efficiency is increased because pump speed is easily adjusted to flow demands, and the motor isn’t running constantly at high speed, regardless of load. Noise is also reduced, especially during operations where pump flow demand is below maximum. Varying the pump speed varies the flow and therefore matches the hydraulic power delivered to the exact amount needed at any point in a machine’s duty cycle, whether during operation, in standby, or while maintaining pressure. In addition, because these systems generally require less oil and consequently a smaller reservoir, the machine footprint can be reduced.
