Hydraulic Accumulator

A hydraulic accumulator can allow a system to increase its cost-effectiveness, offer continuous, dependable operation and are able to store emergency power should there be an electrical failure…

You will usually be able to find an hydraulic accumulator in hydraulic systems and they have two functions: one, to store energy and two, to smooth out pulsations. If your hydraulic system includes an accumulator within it, it will be able to operate with a smaller pump. This is because the accumulator is able to store energy from the pump when the demand is lower. The built-up energy is ready for use the moment it is needed and can be released at a rate much higher than what would be release with the pump on its own.

A hydraulic accumulator can also double-up as surge or pulsation absorbers, just like an air dome used on pulsating piston or rotary pumps. Accumulators cushion the hydraulic hammer, which helps to reduce shocks caused by the quick movement or sudden starting and stopping of power cylinders in a hydraulic circuit.

There are four main types of hydraulic accumulator: the weight-loaded piston-type accumulator, the diaphragm accumulator (also known as a ‘bladder’), spring-type accumulator and the hydro-pneumatic piston type accumulator. The weight-loaded piston-type accumulator was the first to be used, however it is much larger and heavier than a modern piston or bladder accumulator. This version of the piston accumulator and the spring-type are seldom used nowadays, but the hydro-pneumatic accumulators are the kind that are most commonly found in modern hydraulic systems.

What are accumulators used for?

Storing energy – Hydropneumatic accumulators use a gas as well as hydraulic fluid, which can be compressed into smaller volumes at higher pressures. Potential energy is stored in the compressed gas and will be released once it is required. This kind of energy is similar to that of a raised pile driver transferring its huge energy upon the pile. With a piston accumulator, the energy in the compressed gas exerts pressure against the piston separating the gas and hydraulic fluid. This forces the fluid from the cylinder into the system and consequently to the location where it is required.

Pulsation absorption – In a hydraulic system, pumps create the power that needs to be used or stored. The majority of pumps distribute this power in a pulsating flow. As the piston pump is usually used thanks to its ability to operate under high pressure, the pulsations can be damaging to a system working under high pressure. An accumulator cushions the system against the pressure variations.

Shock cushioning – There are a number of hydraulic applications where the driven member of the system makes a sudden stop, which produces a pressure wave that moves back through the system. During operation, this means that the peak pressures that appear are much greater than the usual working pressures. This creates unpleasant noise or in severe circumstances, system failure. The accumulators gas cushion can help to reduce the shock.

Maintaining pressure – When the liquid in a hydraulic system is exposed to rising and falling temperatures, it causes pressure changes. There could also be drops in pressure due to a hydraulic fluid leak. By giving or taking a little bit of the hydraulic fluid, a hydraulic accumulator compensates for pressure changes.

Fluid dispensing – Accumulators are able to distribute small volumes of hydraulic fluid, including as soon as they are required.

Hydraulic AccumulatorsA couple of examples of some of the work we’ve undertaken include some Parker bladder accumulators that were for a UK-based electro-mechanical equipment exporter and on the right, these accumulators that were despatched to a company who specialise in the services and repair of plant and hydraulics. They were 10 litre nitrile bladder accumulators with elastomeric seals. They have a maximum pressure of 345 bar. We have also dispatched a .75 litre accumulator with a maximum pressure of 350 bar, pressure on port line: 10-70 bar, maximum back pressure on tank line: 3 bar, minimum pressure: 10 bar and oil capacity of 12 litres/minute.

You can find out more about the accumulators we’ve provided in our blogs here and here.

Bonfiglioli Hydraulics - Press Release

Bonfiglioli wheel-traction drives improve precision and efficiency in Huddig revolutionary Tigon Technology backhoe loaders.

Bonfiglioli has designed and developed a dedicated solution to the new full hybrid technology machine created and manufactured by Huddig, a leading backhoe loader manufacturer in Sweden.

Bologna, Italy, March 2, 2017- Bonfiglioli, a leader in the manufacture of gearboxes, gearmotors and drive systems, has announced the development of the 600 series wheel-traction drives – specifically designed for Tigon Technology backhoe loaders, manufactured by Huddig. Each of the special 4-wheel traction drives is capable of reaching an output torque of 40.000 Nm, and is driven by a liquid cooled 30kW electric motor. The independent control of each wheel improves the backhoe loader’s performance on slippery surfaces. The Bonfiglioli 610 drives also increase the precision of the machine, making maneouverability easier in tight spaces, e.g. in building sites located at city centres. And in line with Huddig’s requirements, the 4 drives are perfectly quiet.

Tigon Technology by Huddig, is a hybrid technology that combines diesel and electric power allowing energy generation and regeneration in a way that has never been possible before for construction machinery: the concept machine achieves significantly lower fuel consumption than a traditional backhoe loader. Based on this technology and equipped with Bonfiglioli 4-wheel traction drives, the new Huddig hybrid backhoe loader stands apart from other types of construction equipment without producing emissions.

Bonfiglioli has been designing and manufacturing drives for the construction and off-highway industry for more than 40 years. Already a leader in these markets, Bonfiglioli increased its offering in 2015 with the acquisition of O&K Antriebstechnik and now offers the widest range of final drives on the market, including the largest final drive ever made (up to 3000 kNm torque). Over 30 years ago, Bonfiglioli combined its competence in electric motors with expertise in final drives to begin producing electric and hybrid technology products for mobile equipment, and now offers a complete portfolio of electromobility solutions – find out more about the Bonfiglioli product range here.

Back to our new customer down in Antarctica…

When we say we trade the world over, we aren’t joking! A recent enquiry came from a new customer in Antarctica, who sent the team a photo of a hydraulic pump. Not knowing what they wanted and with the identification plate missing from the unit, the team were tasked with finding out what type of hydraulic pump it was. We never back away from a challenge!

Surely enough, the team identified the pump as a Denison P Series tandem pump and were able to quote on a seal kit to needed to undertake some important repairs on the pump; the pump came from a pristine environment into which the unit had been leaking – a repair was essential.

But sometimes a repair may just not be feasible, providing poor or unreliable performance at best. If this is what we find, we will always contact you to explain why and to quote for a brand new replacement pump.

Hydraulic Gear Pump

Looking for a hydraulic gear pump? We offer extensive access to a vast range of hydraulic manufacturers from around the world…

Hydraulic manufacturersParker, Roquet, Bosch Rexroth, Casappa, Eaton, Caproni, Turolla, Vivoil Vivolo, Ronzio, Salami and Bondioli and Pavesi are just some of the hydraulic gear pump brands that we regularly supply.

The technical team here at Hydraulics Online have more than 75 years’ combined experience between them, so don’t worry if you don’t know what you’re looking for, or can’t identify an existing pump that you’re trying to replace. Leave that to us. And with our ISO 9001 accreditation, you can relax knowing that you’re in capable hands.

Hydraulic gear pump

Large or small, a hydraulic gear pump is a simple and economical pump that creates pressure through the meshing of the gear teeth, forcing fluid around the gears to pressurize the outlet side. They may be quite loud during operation, but modern gear pumps are hugely dependable and much quieter than their older counterparts.

A hydraulic gear pump can be found in a variety of hydraulic systems. They have few moving parts, work effortlessly, and operate easily even with pressures of up to 250 bar. The displacement chambers are located between the housing of the pump and the rotating gear wheel.

There are two main types of hydraulic gear pump…

External hydraulic gear pump

External gear pumps – These pumps are typically found in industrial and mobile applications, e.g. log splitters and lifts. Some of the features of this pump include:

  • Light-weight;
  • High working pressures;
  • Variety of speeds;
  • Large temperature and viscosity range (i.e. flexibility);
  • Low cost.

Internal hydraulic gear pump

Internal gear pumps – These pumps are used predominantly in non-mobile applications e.g. machine tools and presses or fork-lifts. Key features of the internal gear pump include:

  • Low flow pulsation;
  • Decreased operating noise;
  • High efficiency.

Hydraulics CatalogueAs we said, if you’re not sure what sort of pump would be suitable for your application that’s no problem for our technical team; we are always up for a challenge and can usually work miracles with unrecognisable or seemingly obsolete hydraulic pumps and equipment too. We also undertake hydraulic pump repairs and refurbishment and can often offer “direct equivalents” where it is more cost-effective to do so. Don’t forget to visit our catalogue to see the different types of hydraulic gear pump we supply.

Hydraulic Cylinder

Whether you’re looking for a single or double-acting, tie-rod, marine, subsea or welded hydraulic cylinder, something standard or made-to-order, we have it covered…

Better still, you can relax knowing that you’re dealing with a company with over 75 years’ technical experience, backed by ISO 9001 accreditation… and that means that you’re in safe hands. We never compromise on quality. Ever.

… I searched for ages to find the right size hydraulic cylinder and you guys came up trumps. Excellent service… really helpful.

If you’re looking for a “standard” hydraulic cylinder, then hop over to our catalogue where we showcase some of the more popular hydraulic cylinders we have on offer:

Hydraulic cylinder catalogue

If you can’t find what you’re looking for, you can always contact one of our hydraulic engineers – they love to talk – or fill in a stock enquiry form. If you’re looking for something a bit different, then our Bespoke Hydraulic Cylinder Design Form will help you capture the information we need to design a custom-made hydraulic cylinder tailored to your specific requirements and operating parameters. Just fill in as much as you can… we can work through the rest together afterwards.

Let’s take a quick look at the different types of hydraulic cylinder design available…

Tie Rod Cylinder: Tie rod style hydraulic cylinders use high-strength threaded steel rods to hold the two end caps to the cylinder barrel. This technique is most often seen in industrial factory applications. Small bore cylinders usually have 4 tie rods, while large bore cylinders could need as many as 16 or 20 tie rods to be able to keep the end caps under the extreme forces generated.

Welded Cylinder: A welded body hydraulic cylinder doesn’t have tie rods. The barrel is welded directly to the end caps; the ports are welded to the barrel; the front rod gland is then usually threaded into or bolted to the cylinder barrel. This enables the piston rod assembly and the rod seals to be removed for service.

Telescopic Cylinder: The length of a hydraulic cylinder is the total of the stroke, the thickness of the piston, the thickness of bottom and head and the length of the connections. If this total length does not fit in the space available, then a telescopic hydraulic cylinder enables the piston rod to also be used as a piston barrel housing a smaller second piston rod.

Plunger Cylinder: A plunger cylinder can only be used as a pushing cylinder; the maximum force is piston rod area multiplied by pressure. This generally means that a piston cylinder has a relatively thick piston rod.

Differential Cylinders: A differential hydraulic cylinder moves like a normal cylinder when pulling. However, If the hydraulic cylinder has to push, the hydraulic oil from the piston rod side of the cylinder is not returned to the reservoir, but instead is forced to the bottom side of the cylinder. This means the cylinder moves much faster, but the maximum force the cylinder can give is like a plunger cylinder. A differential cylinder can be manufactured like a normal cylinder, only a special control is added.

Rephasing Cylinders: Rephasing hydraulic cylinders are a combination of two or more cylinders plumbed in series or parallel, with the bores and rods sized such that all rods extend and/or retract equally when flow is directed to the first, or last, cylinder within the hydraulic system. In “parallel” applications, the bore and rod sizes remain the same, and the hydraulic cylinders are always used in pairs.

Single and Double-Acting Cylinders: A double-acting hydraulic cylinder is a cylinder in which the working fluid acts alternately on both sides of the piston. It has a port at both ends, provided with hydraulic fluid for both the retraction and extension of the piston. A double-acting hydraulic cylinder is used where an external force is not available to retract the piston or where high force is required in both directions of travel. With a single-acting cylinder, when fluid flow is applied to a port in the closed end, the shaft extends until the collar or piston reaches the shaft end. When an external weight or load is placed on the shaft, the shaft will retract into the chamber until the piston or collar reaches the closed end. The cylinder generates an output force at the shaft end in proportion to its internal closed end area multiplied times the pressure potential of the fluid power system.

Can you let the boys know that they are providing us with great service, parts and information in all our locations. Your service is prompt and reliable; you’re our “go to” guys when it comes to hydraulics.

We’ve supplied hydraulic cylinders to customers all over the world, literally, in a vast range of markets…

Hydraulic Cylinders… including an international refuse and waste management services company who needed a number of 3-stage telescopic, double-acting hydraulic cylinders, and a power transmission equipment manufacturer who needed a complete hydraulic system and hydraulic cylinders for a tipping hopper application.

Welded Hydraulic Cylinders

Then there was the new overseas customer, a leading product design and manufacturing company within the renewable energy industry, who contacted our technical team needing support on a new product development project. Having used a tie-rod cylinder within one of their product designs before, they wanted to prototype a welded construction hydraulic cylinder instead. The cylinders (pictured right) were made to order for the customer… Remember that bespoke cylinder design service we spoke about?

 

These bespoke double-acting hydraulic cylinders pictured were designed as part of a bigger system design project for a new prototype machine for a British Original Equipment Manufacturer. We love bringing ideas to life!

 

And finally… If you’re just looking for technical information, then the good news is that we have a number of articles that may be of interest: how hydraulic cylinders work, hydraulic cylinder maintenance, hydraulic cylinder seals, hydraulic cylinder testing, hydraulic cylinder repair and hydraulic cylinder storage.

Parker Hannifin

Parker Hannifin offer a huge range of hydraulic products for both mobile and industrial applications…

Parker HydraulicsUsually considered to be the world’s leading manufacturer of motion and control technologies, the Parker Hannifin hydraulic product range includes: accumulators, cartridge valves, controls, filters, pumps and motors, systems, valves, cylinders, hose and accessories:

As an ISO 9001 accredited company, we are resolutely committed to quality and continuous improvement – that extends to only ever supplying top quality hydraulic equipment and components. We simply won’t put our name to anything less. Ever.

It’s genuinely hard to think of an industry, market or corner of the world where we haven’t been involved to date – You name it, we’ll have done it! Our competitive pricing and deliveries are backed by over 75 years’ combined technical experience, or in the words of a customer:

… you don’t just shift boxes, you know your business inside out.

As a quick example of a Parker Hannifin enquiry that we’ve handled in the past, a UK-based ship maintenance and services company, contacted our technical team about a Parker Hannifin Commercial Hydraulics P365 Series pump. After quoting on the unit we also provided a quote on a “direct equivalent” with a lower cost and quicker lead time.

Parker Hannifin

The equivalent P365 pump is a quality, British product which offers identical features and performance to the original Commercial Hydraulics pump. The customer ordered the direct equivalent and took delivery sooner than later – with leftover cash to spare!

We like a challenge…

You guys really helped me out last time I was stuck (was how an email from a returning customer began recently, and it continued)… I apologise for the lack of available details.

Parker Hannifin electrohydraulic stroker 2

The email came from a worldwide marine engineering and underwater services provider, the email itself having been written by the Ship Superintendent of a vessel that was “struggling as one of her Linear Cable Engines has developed a serious problem and is now out of action.” Challenge accepted!

Our technical team have a reputation for consistently providing practical, trusted advice and solutions backed up by an ability to deliver – supplying both well-known and niche products – even against the most challenging of timescales and budgets. In this particular case, within 24 hours our team had worked with the small amount of information available to identify and quote the equipment required – a Denison Hydraulics electrohydraulic stroker (S23-12413-0, EHS 5A* with deadband) to suit a Denison Gold Cup pump, type P14P. Another happy customer!

Don’t forget…

With quality in-demand products, lead times can sometimes become protracted creating a challenge for end users and original equipment manufacturers alike. But here at Hydraulics Online we like a challenge…

Parker PumpAs an example, a company specialising in the design and manufacture of heat exchangers contacted our technical team requiring 5 Parker PV Series axial piston pumps on a quick delivery time. They had already contacted a number of other hydraulic suppliers, only to be consistently told that delivery times would be 8-10 weeks. We tried harder…

Our technical sales team have a wealth of knowledge between them, over 75 years to be precise, and don’t like to be beaten. And they weren’t. We were able to quote the 5 Parker axial piston pumps that the customer needed on a much reduced 5 week lead time. And, as an ISO 9001 accredited company we consistently deliver against our promises and do what we say we’re going to do. The result? Another very happy customer who took delivery of his Parker PVplus pumps in just over half the time that he had originally been led to believe would be possible.

We export to over 150 countries worldwide – technology and extensive carrier networks actually make the world a very small place – and in addition to Parker PV series axial piston pumps, we supply a huge range of other hydraulic pumps including: gear pumps, rotary vane pumps, fixed displacement pumps / screw pumps, bent axis piston pumps, axial piston pumps and radial piston pumps. If you’re up against particularly tight deadlines or budgets, we can often offer quality, direct equivalents to well-known hydraulic brands, then there’s our hydraulic repair service offering an alternative cost-effective solution for you.

Parker hydraulic pump GR Screw PumpOffering a long service life and quiet operation, Parker GR screw pumps are dependable, economical low pressure pumps free from pulsations. These rotary pumps with axial flow have only three moving parts and can be installed in any position, as well as above oil level. The secondary screws act as seals and are turned hydraulically by the fluid being pumped.  There is only a rolling action between the main screw and the secondary screws, which eliminates noise and vibration.

A number of other brands come under the Parker banner too; the Parker hydraulic pumps range actually also includes “Commercial Hydraulics” and “Denison Hydraulics” pumps.

The Commercial Parker hydraulic pump range…

Commercial Hydraulics are now part of the Parker Group, with the Commercial Parker hydraulic pump series often referred to as the industry standard against which all others are measured. Previously branded Commercial pumps, motors and flow dividers are still made to the same exacting standards by Parker; the only difference is that the previous Commercial product codes are now preceded by “PG” (Parker Group).
