Hydraulic machines are used in many industrial applications to accomplish significant work requiring high amount of mechanical energy in a single stroke. Hydraulic machines perform this work through the use of the high pressure fluid method. The fluid which is typically oil is pumped from a reservoir to the cylinder with the help of hydraulic pump to actuate the piston. Thus, a hydraulic pump needs to generate enough pressure to overcome the pressure induced by the piston load. The pump creates a vacuum at the inlet which draws the fluid from the reservoir to the hydraulic system. Hydraulic gear pump is fixed displacement pump which has a set flow rate.

Hydraulic gear pump moves a high amount of fluid with a constant flow rate at relatively low pressure. They are best suited for mobile equipment as most of the hydraulic machines need a constant flow rate for their operation. Thus, hydraulic gear pump finds its applications in many agricultural and construction machines which require less pressure up to 3000 psi. On the basis of design, hydraulic gear pump can be classified as external and internal gear pump. The internal gear pump is majorly used in mobile applications due to its capability in handling thick fluids and providing high efficiency compared to external gear pumps. Hydraulic gear pumps are cheaper as compared to vane pump, axial piston and radial piston pump due to simplicity in construction. Further, the maintenance required and number of breakdowns in gear pump is lesser as compared to other types of hydraulic pump. This is due the gradual wear down of the main bushing due to the less stress exerted on gears.

Another major component which controls the flow of fluid in a hydraulic machine is a hydraulic valve. A hydraulic valve is capable of controlling the flow of fluid in a cylinder and thereby maintains the required pressure in the system. A hydraulic valve consists of a spool which slides to different positions and thus controls the flow of fluid. The hydraulic valve can be categorized on the basis of applications into directional valve, pressure valve and flow valve. Hydraulic control valve is designed to be stackable, with each output valve used for particular operation and a single input valve for supplying fluid. These valves need to have a high tolerance for withstanding high pressure and avoid any leakage of fluid. Thus, the price of the control valve is high compared to other parts of a hydraulic system. The hydraulic valve and gear pump work in parallel to control the pressure of fluid inside a cylinder. Thus, both the components are very crucial considering the operation of mobile hydraulic system. Most of hydraulic component manufacturers provide a range of products under these two categories in order to cater to the demand from customers. Some of the hydraulic gear pump and control valve manufacturers are Eaton Corporation Plc, Peerless Engineering, Bosch Rexroth AG, Danfoss Power Solutions, Permco, Inc., Actuant Corporation, Parker Hannifin Corp., Atos spa, Dalian Hydraulic Component Co., Ltd., Bailey International, Hydreco Hydraulics Pty Ltd., Bondioli & Pavesi S.p.A., Hawe North America, Inc., Haldex AB and Casappa SpA.

Electronics Simplify Wheel Loader Operation

Advanced electronic technologies continue to simplify wheel loader operation, resulting in increased productivity for both experienced and novice operators.

Electro-hydraulic (EH) controls have gained popularity in the mid-size wheel loader market and bring many benefits including return-to-dig, soft stops at the end of the hydraulic cylinder stroke and customizable hydraulic response settings.

“Electro-servo hydraulic controls enable the return-to-dig feature and end-stroke dampening,” says Eric Yeomans, product manager, wheel loaders, Volvo Construction Equipment. “This allows the operator to set detent functions, as well as bucket and boom positions from inside the cab with switches found on the right-side A-pillar. EH controls also provide the ability to adjust the lever response control. There are three settings available – active, normal and soft – so an operator can adapt the control behavior to his or her liking.”

Troubleshooting Challenge: Shaft Seal Fails on Pressure-Compensated Pump

A simple 2,000-psi hydraulic system was designed and installed to run a conveyor in a hog-processing plant (see schematic). Two belt conveyors at a vertical angle to each other create a V shape, with about a 12-in. gap at the bottom and about a 30-in. gap at the top. A flat floor at the bottom of the conveyor slopes down from the entrance. Hogs travel down single file into the conveyor. As they enter the conveyor, the sloping floor causes the hogs to be wedged in and carried to where they are dispatched, and processing begins.

The new system developed a problem with the C-face mounted pump shaft seal failing after six weeks or so. The seal lip with a garter spring was pushed out. The maintenance crew replaced the seal and was told by the power-unit builder that this type of failure was normally due to excessive pump case pressure. The crew installed a standard 0- to 300-psi pressure gauge teed into the case line to monitor case pressure.

They observed it for several hours, then every day for a week or two. They noticed that when the pump compensated each time the conveyor was stopped, the pressure would spike between 10 and 15 psi but then only read about 5 to 8 psi. When the directional valve was shifted to run the system, the pressure would drop even lower.

The pump shaft seal failed again five weeks later. The power-unit builder said case pressures this low shouldn’t cause these failures, but they did not know what could be causing the failures.

Do you have any ideas?

Electro-Hydraulic Pump System reduces fuel costs on high-power lifting applications

The new integrated solution provides the opportunity to realise fuel cost savings of up to 50% and gives the potential for customers to downsize or remove the diesel engine, therefore creating an optimised, highly-efficient, completely electric vehicle.

There is a huge shift towards electrification across many areas of industry and society delivering environmental and sustainability as well as performance benefits. As a result, large numbers of OEMs are looking to tap into the technology which also supports improved maintainability, greater safety, and compliance with increasingly stringent emissions regulations.

Conventional solutions in this area work with coupled power distribution, where the engine is sized for peak demand with no energy storage or recovery capability. In addition, the efficiency (torque/speed operation) of the internal combustion engine (ICE) tends to be low.

With its EHPS, Parker has addressed a market need for decoupled loads and power distribution. This design concept facilitates far better engine management whereby energy storage and recovery functions can be introduced. With its separate drive train, the EHPS also offers high ICE efficiency via power point operation.

Parker’s system solution comprises motor and pump technology to recover energy while materials are being lowered – all controlled by a power inverter. Embedded Parker-derived software provides the system function and operational interface, while peripheral manifolds and system components deliver functionality to key services throughout the wider hydraulic system.

TRACTORS: THE BACKBONE OF THE FARM

The astonishing production capability of modern agriculture can, in no small part, be attributed to the tractor. Once the internal combustion engine hit the farm, there was no turning back. Farms grew bigger, with farmers able to cover more ground faster. Cash crops replaced oats needed for horses. Family size became smaller as less labor was needed to farm.

Rural America was forever changed.

Today’s tractors are incredible, amazing, powerful feats of mechanical engineering and precision.

MANUFACTURERS UNVEIL NEW TRACTORS
New innovations in tractor technology are coming out all the time. In other words, it’s not your grandpa’s tractor anymore. In 2018, equipment manufactures seemed to focus on combines. In 2019, their shift has turned to tractors. Sales are up nearly 5%, and the new models offer innovative possibilities.

CASE IH unveiled its AFS Connect Magnum series at the National Farm Machinery Show, with its updated exterior and cab design and improved precision technology.

Other manufacturers feature versatility to perform multiple operations around the farm, along with improved precision technology.

John Deere’s new 6230R and 6250R models focus on the needs of livestock and hay producers with an infinitely variable transmission (IVT) that allows the machine to accelerate quickly, haul heavy loads, and reach optimal transport speed in a hurry, making it perfect for baling and hauling hay. An improved factory-installed command center works smarter and adds to driver comfort.

John Deere also has updates to its largest lineup of tractors. The new John Deere 9R series offers 120-inch track spacing and 30- and 36-inch tracks to help reduce field compaction and increase stability on hilly ground. A new command center and software upgrade is geared toward saving fuel and allowing more acres to be covered in less time by reducing overlap. A hydraulic kit, in either factory or field installed versions, helps manage implements that require continuous hydraulic power. The kit is retrofittable on some older models.

Making Sense of Hydraulic Hose Standards

Hydraulic hose construction and performance is covered by various national and international standards including ISO, BSI, SAE, DIN, API, and CETOP. Most proprietary hoses conform to one standard or another, the SAE standards being the most widely followed in the U.S. SAE standards provide general, dimensional, and performance specifications for the most common hoses used in hydraulic systems on mobile and stationary equipment.

For decades, SAE J517 has published guidelines for 100R1 through 100R12 series hydraulic hoses. These manufacturer-driven SAE standards have been based on design, construction, and pressure ratings to ensure that hydraulic hoses meet minimum construction requirements. SAE established minimum pressure ratings for various hoses (inside diameters and were later revised to also include constant-pressure hoses, which are hoses that maintain pressure ratings within a group regardless of size). Some common constant-pressure hoses are R13, R15, R17 and R19.

What Happens When Hydraulic Systems Get Too Much Sun?

Most of us are aware that prolonged exposure to the sun—especially in hot weather—can wreak havoc on rubber, polymers, and other synthetics, rendering them weak and brittle. But prolonged exposure to the sun can also cause problems inside a hydraulic system.

Hydraulic component failures from pressure overload have been reported in agricultural equipment, which often is left exposed to the sun for long periods when it is not being used. These pressure overloads can be above and beyond system relief valve settings, and they occur while equipment is shut down, rather than when it is operating. These seemingly improbable events result from thermal radiation absorptivity from prolonged exposure to the sun.

Many designers believe that system relief valves will prevent such heat-related high pressures from developing or that expansion of hydraulic hoses will absorb any pressure increases. They will, but many system designers do not specify relief valves in the implement because they rely on relief valves in the tractor’s hydraulic system.

Obviously, the problem is more complex. Through laboratory stress analysis of a failed component, the pressure that caused the failure can be computed. Working backward from that number, an analysis of the situation can be made.

A Typical Scenario
Let’s begin with this scenario: Assume the failed component came from an agricultural implement. The implement had been disconnected from the tractor on a fall day. It was a heavy implement that could trap 2,500 to 3,000 psi in its hydraulic system. Further assume that the ambient temperature was between 20° and 30°F on that fall day. If we know what the failure pressure is, and subtract the trapped pressure, what remains is the amount of pressure that would have to be generated by external sources to cause failure.

For this thermal-expansion problem, the bulk modulus of the fluid is a key factor. The bulk modulus for typical hydraulic oils ranges from 240,000 to 250,000 psi and varies with temperature. For this example, we’ll use an average value to get a useful indication of the possibility of thermally generated pressure increases.

First-person digger: Stanley Black & Decker’s game controller for excavators

In a parking lot at an industrial and office park just outside Baltimore, I took an excavator for a spin. I pushed around some cinder blocks with a leveling blade, nosed them around with the excavator’s shovel, and maneuvered the heavy metal beast around to make room for an incoming tractor-trailer. And I did all of this with a wireless controller that was almost identical to the one I used to play Forza the night before.

The excavator was configured with a prototype of the Remote Operated Control (ROC) System from Stanley Black & Decker’s Infrastructure Innovation unit—a bolt-on remote control system that allows heavy machinery from major manufacturers to be operated either from in the cab as usual or with a wireless game-style controller.

Stanley is currently recruiting contracting companies to act as beta testers for the technology, which is currently being targeted at Bobcat, CAT, Kubota, and John Deere excavators under 10 tons. The remote control kit can be installed in existing excavators in about 5 hours by someone with little to no mechanical experience. And the control system has a physical switch that allows an operator to quickly switch back and forth between local and remote control.
