Rotary Vane Pump Offers High Vapor Capacity for Aggressive Gases

Pascal 2021 HW two-stage rotary vane pump is said to offer the highest vapor capacity in its class, making it suitable for working with aggressive gases in freeze drying and medical sterilization applications. An optimized design and gas ballast system allows the pumping of large volumes of vapor without condensation inside the pump. This prevents accumulation of fluid that would adversely affect the service life of the pump and the pump oil. The pump is constructed of materials that tolerate aggressive chemicals, such as hydrogen peroxide. The pump is ready to deliver vapor in just a few minutes due to a customized temperature management system. Its safety device impedes the water from entering into functional sections of the pump if the steam capacity is inadvertently exceeded. Its compact design enables easy installation into OEM and custom equipment.

Alleviating Firing System Safety Risks And Costs

The need to streamline perforating operations while alleviating the risk of misfires, assembly and downhole time, labor and maintenance costs is a key component to hydraulic fracturing operations, particularly when completing long horizontal wellbores in unconventional shale plays. DynaEnergetics’ DynaStage perforating system incorporates technology in the addressable firing system and an improved mechanical design to help improve overall plug-andperf (PNP) operations. It optimizes perforating operations with fully assembled and ready-to-shoot gun modules delivered to the base or well site.

The fully disposable, maintenance-free system is made more robust by eliminating traditional approaches to selective perforating, detonators, gun hardware and accessory equipment and, with its additional safety features, allows other wellsite operations to run in conjunction with the perforation process.

System features

The system includes intrinsically safe, integrated switch-detonators, preassembled guns with shaped charges and a composite plug, a firing panel, and a surface tester. Commercialized in 2016, the DynaStage system has targeted two areas to improve efficiency and reduce costs.

The first is safety, for which the system has a simple design that eliminates the risk of inadvertent detonation from stray current or voltage. Surface explosive handling and arming can be conducted in less time and in conjunction with other operations. The design eliminates the need to hold the gun system at shallow subsurface depth during simultaneous operations. Both factors reduce wait times at the well site.

The second targeted area is reliability. The design of the electronic system and simplification of the mechanical field assembly process help to reduce the number of misruns, which increases efficiency and lowers the cost of completions.

Improved assembly at surface

During the assembly of conventional perforating systems, including mechanical component assembly, arming the system and connecting the gun string to the wireline, there is a risk that resistorized detonators can be initiated with radio frequency energy, stray current or stray voltage on the surface. These traditional detonators can contribute to an increased risk of injury and destruction when connecting the detonator to the gun string and wireline truck.

Improve your haul cycles

Haul road design, construction, and maintenance have a huge impact on truck haulage cycle efficiency, costs, and production. Design factors, including road materials, grades, curve designs, and traffic layout, play critical rolls in efficient truck haulage. But proper maintenance of roads — to ensure smooth surface conditions, low rolling resistance, and consistent grades — is equally important to achieving lowest cost per ton of material hauled.

As an example of the importance of haul road design and maintenance, a 5-percent increase in rolling resistance can result in as much as a 10-percent decrease in production and 35-percent increase in production cost. Though 5-percent rolling resistance doesn’t sound like much, it is equivalent to about 2 inches of tire penetration.

Good haul road design, construction, and maintenance reduce fuel burn, help minimize tire heating and damage, and reduce wear on truck components. The results are lower operating and maintenance costs and less downtime.

Motor graders play critical role

Motor graders are not only critical to maintaining haul roads, but also to building haul roads to the right specifications, which, in turn, enables the roads to resist damage and provide optimum hauling conditions for longer periods.

Motor graders are the best grading machines for ensuring that cross slopes and cross falls are built to specifications. Building to spec helps ensure that roads drain water efficiently, which reduces the formation of potholes and washboards, and reduces the need for frequent haul road maintenance.

Motor graders are also the best machines for building superelevated curves. Such curves help trucks maintain proper weight distribution and constant speed, reducing the frequency of transmission gear shifts and braking for less wear on truck components.

After roads are built, the motor grader is the most efficient tool to keep them in good condition. Motor graders provide smooth roads, constant grades, and reduced rolling resistance. They also can maintain safety berms and drainage ditches, and, with their fast travel speeds, graders can be dispatched to quickly clean up rock spillage from haul trucks.

Hydraulic Actuators Handle Heavy Doors

Hydraulic systems are often the first choice for opening and closing gigantic one-piece doors used on airplane hangars, agricultural buildings, and structures requiring large openings. Sometimes exceeding 100 ft. in width and weighing well over 10,000 lb., these doors need powerful mechanisms to operate smoothly and dependably. Hydraulic power is ideal and adaptable to any size door by increasing cylinder size in proportion to door size and weight.

One-piece doors are preferable in these applications because they swing up and away from the building, and their operation is simple. They do not protrude inside the structure like roll-up doors, which can reduce headroom. Bifold doors, on the other hand, pivot outward as they are raised. This feature presents a different set of advantages and disadvantages. Because bifold doors lift from the bottom, lifting force can be distributed across the width of the door. An electromechanical drive is generally used for these doors, but because one-piece doors must be pivoted from both sides, hydraulics is generally used.

A big advantage of the one-piece doors is that they provide a large, shaded canopy outside the building when open. With hydraulic power, the doors can be clad with almost any material, including heavy glass and steel siding. Entire storefronts have been incorporated into door designs.

Smart Hydraulic Design

Schweiss Doors, Hector, Minn., offers both types and has developed design features specifically addressed to improve hydraulic door operation over other designs. At the heart of the company’s system is a hydraulic gear pump driven by an electric motor ranging in size from 2 to 20 hp. The complete hydraulic power unit (HPU) is a compact package that can be mounted anywhere in a building, whether on the floor or a wall close to the door or farther away.

UL-listed electrical components are housed in control boxes, including contactors, transformers, relays, motor timers, rectifiers, and control fuses. The gear pump is 95% efficient and operates quietly at 1,800 rpm. The HPU also incorporates a 3,000-psi pressure gauge, fluid temperature gauges, and a service filter.

Structural features include a proprietary hinge design that provides considerably greater surface area than standard hinges for distributing the load of the moving door evenly. The patented hinges each feature four connection points, with grease-lubrication and removable hinge pins for extended service life. Spherical bearings connecting cylinders on each side of the door to the door frame and the building accommodate horizontal movement or deflection. They also allow for flexibility of the door and frame without binding on the cylinder pins and brackets.

Specifying the Right Hydraulic Cylinder for the Right Job

Hydraulic cylinders essentially convert fluid pressure and flow into force and linear motion. They are available in a wide range of styles, sizes, materials, and configurations. Many OEM engineers play it safe by over-engineering cylinder specifications. But less can sometimes be more when it comes to complex hydraulics. Let’s first identify some of the key factors that should be considered when specifying hydraulic cylinders.

Design Factors for Hydraulic Cylinders

Specifying hydraulic cylinders is essentially a balancing act or a cascade of compromises, as each design factor influences one or more of the other design factors. Designers must weigh each positive effect against potential negatives to get the best performance. Here ‘s a concise look at those factors:

Capacity. Most industrial hydraulics are considered medium-duty and operate at 1,000 psi. Heavy-duty hydraulics, which are common in presses and automotive machinery applications, can handle pressures up to 3,000 psi. If loads are extremely high, tandem cylinders are preferred to larger-bore or custom high-pressure cylinder designs.

Stroking distance. Stroke distances can exceed 10 ft (5.05 m) for custom-built cylinders, but pressure ratings can be a problem with such long strokes. The rod diameter needs to be determined in order to gauge its ability to handle the load. If necessary, a pressure rating on load in thrust (push mode) must be specified. In horizontal applications, which are common, premature rod bearing wear can lead to rod sag over long strokes. Although custom stroke distances above 10 ft (3.05 m) are possible, pressure rating can be a concern.

Speed. Every application engineer has their own definition of “excessive speed.” A good rule of thumb is that standard hydraulic cylinder seals can easily handle speeds up to 3.28 ft/sec. (1 m/sec.). The tolerance threshold for standard cushions is roughly two-thirds of that speed. Standard low-friction seals are often a better choice for high-speed applications, but what you gain in one aspect of performance you lose in another. The higher the fluid velocity, the higher the fl

Hydraulics Technology is Alive and Well, Thank You

Rumors of fluid power’s death have been greatly exaggerated. To the contrary, electronic control and more-sophisticated components have advanced hydraulic power transmission far beyond its state of the art from only a few years ago.

I have been doing hydraulic motion control projects for 35 years. During that time, I have seen pundits predict the imminent demise of the hydraulic industry. So why hasn’t it happened? The answer is simple. Advances in hydraulic technology and training have allowed the inherent benefits of hydraulics versus other means of powering machines and mobile equipment to be demonstrated in real applications.

Two decades ago I was sitting in front of a major hydraulic company’s vice president of valves. The vice president didn’t seem to be all that interested in servo control because it was less than 5% of his company’s total business. He also deemed servo control as a little risky. Some people might have been discouraged about that, but it was obvious an opportunity existed to increase that percentage by replacing traditional on-off hydraulic valves with computer-controlled hydraulics.

Need for Better Control
The opportunity seemed clear. In essence, replace old open-loop “bang-bang” systems with hydraulic servo controls that could execute all the commands a servo motor controller could and move with the same precision. This was a lofty goal because feedback from magnetostrictive displacement transducers (MDTs) in the mid-1990s provided only about 0.001-in. resolution. Servomotors using encoders could achieve better than 0.001-in. resolution. However, hydraulic servo controllers now can use the same feedback devices as servo motors can. The playing field has been leveled. MDTs with 1.0 µm resolution are now the norm—and if they aren’t, they should be!

Back in the 1980s, one of my first hydraulic “control” applications had to move a block of wood into position at a lumber mill. One high-speed valve and one low-speed valve were controlled by two digital outputs. The operation was simple enough:

New Bobcat Bob-Dock System is Designed for Repeatable Hydraulic Connections

Bobcat Company introduces the new Bobcat® Bob-Dock™ system – a cutting edge, hands-free hydraulic attachment mounting system. The Bob-Dock mounting system is designed for strong, easy and repeatable hydraulic connections, without operators leaving the Bobcat compact loader cab.

The Bob-Dock system will be available for M2-Series T630, T650, T740 and T770 compact track loaders; S630, S650, S740 and S770 skid-steer loaders; and the A770 all-wheel steer loader.

“Fleet owners, equipment managers and operators who worry about machine downtime will love the Bob-Dock mounting system because it prevents many common operator errors, like failing to disconnect hydraulic hoses before backing away from an attachment, and the system routes and protects auxiliary hydraulic hoses from tire and track contact,” says Jason Boerger, Bobcat Company marketing manager. “The Bob-Dock system is also going to be a favorite of operators who will appreciate not having to leave their cabs to connect or disconnect hydraulic hoses.”

How it works

To connect an attachment to a compact loader equipped with the Bob-Dock system, an operator lines up the loader with the attachment’s Bob-Dock adapter plate. The operator then presses the Power Bob-Tach® switch inside the cab. The Bob-Tach system secures the attachment, while the Bob-Dock system automatically connects the hydraulics. The attachment is then ready to use.

When you’re done using the attachment, retract the Bob-Tach wedges and pull away. The hydraulics instantly release, providing simple, hands-free removal.

Versatile and made for easy use

If a loader has a Bob-Dock attachment mounting system installed, and the operator wants to use an attachment that lacks a Bob-Dock adapter plate, it’s no problem. While the Bob-Dock™ attachment mounting system’s floating coupler block equips your loader with a hands-free connection point, the standard couplers located on the lift arm remain ready to use. You can utilize the full lineup of approved Bobcat attachments – with or without the Bob-Dock adapter plate attached.
