Hydraulic Training Seminars 2014 - Photos

Both Christchurch and Auckland Training seminars sold out again this year. People for the Auckland seminar came from wide and far - Dubai, Gisborne and Wellington.

For the Christchurch seminar we had people from the Hawkes Bay, Nelson through to Dunedin. SI Class of 2014

We had fun with lively discussions on hydraulics, how the different components worked, why hydraulics fail and how to get longer life out of machinery and general fault finding. Our hydraulic training seminars are such a mine of information on hydraulics that even our competitors attend! 

Some of the highlights - Hands on learning with parts and cross sections of parts passed around the class, stories of Luigi. The tour of Hyspecs products - for some it was like being a kid in a candy factory!

In Auckland another highlight was the tour of the Hytech manufacturing facility where our Manifolds are designed and manufactured.

In Christchurch the test equipment tour had some service engineers wheels spinning.

Some of the feedback we received "my knowledge has greatly increased and taken another persons perspective", "was excellent, can now apply this knowledge at work in practical applications", "The Topics covered gave a good general base on hydraulic components, applications and systems". See more photos on our Face book pageNI Class of 2014Hytech Tour

Hydraulics Overheating?

As summer approaches the extra heat in the atmosphere puts more pressure on hydraulic systems.

Hyspecs recommends, as operating temperature is 60 degrees Celsius. Do not test with your hand, as even touching for a split second is too hot. Instead use the temperature gauge to get an accurate reading.

Eaton recommends a maximum system operating temperature of no higher than 82 degrees Celsius. Keeping your system cool will increase the life of your system and save you money in the long run.

In a perfect hydraulic world all energy put into a system could be transferred to the job at hand, whether it is a cylinder, motor or some other hydraulic machinery. However we are lucky if we get 65-75% of the input energy turned into useful work. The rest gets turned into heat, noise and vibration.

The loss of power can be attributed to many things:

  • High pressure drop across hoses, orifices and valves
  • Mismatched motor sizes in a pressure compensated system
  • In-built inefficiencies in pumps and motors
  • Poorly designed hydraulic systems 

Try as we may to get the system 100% efficient we will never do it, so we are usually stuck with two options to overcome heat:

 Emmegi Water Cooler

  • Build a large oil tank to dissipate the heat. This is usually the easiest and cheapest option if designing a system from new. Hyspecs recommends a tank size of at least 2.5-3 times the maximum flow of oil in the system (not applicable to closed loop systems where the designer can get away with a much smaller tank). 
  • Install a hydraulic oil cooler cable of cooling approximately 30% of the system input power. Oil coolers typically come as either air/oil or water/oil variety. The air/oil coolers are pretty much the same as a car radiator with either an electric or hydraulic fan blowing over the fins to cool the oil flowing inside the radiator. Oil/water coolers are designed to have oil running through a large outer tube with a separate series of smaller tubes running inside this, containing flowing fresh or slat water which carries the heat away from the oil.  Emmegi Air cooler

Engineer Profile - Craig Kemp

Project engineer Craig Kemp says the thrills and excitement of hydraulic engineering are with the large projects undertaken by Hyspecs. Recruited into the Hyspecs team in January 2007, Craig's primary work focus is managing projects in New Zealand and Australia as well as quality control and company process improvements.

Hyspecs are proud of their team here at Hyspecs. This year we have been profiling various staff in Engineering News.

"With our staff of highly proficient hydraulic engineers like Craig, Hyspecs is able to offer customers a complete system solution," Mr Krebs says. "To ensure that our customers' expectations are met, all projects go through a design review process before a final proposal is presented to the customer. The types of projects that we have worked on are varied, ranging from simple hydraulic power units to large marine systems for controlling A-frames, deck winches and cranes."

Hydraulic Motors - how stuff works

Hyspecs provides a full range of hydraulic motor with a brief explanation of each hydraulic motor category below. Click the headings for more detailed information.

Gear Motor

Consit essentially of two intermeshing toothed gears enclosed in a common housing.

Gerotor/Geroler Motor

The H series motor uses a Gerotor while the rest of the Char-Lynn motors use a Geroler.

Piston Motor

Axial piston Motors are displacement machines in which the pistons are arranged in parallel to the axis of rotation of a cylinder barrel.

Swash-Plate Motor

In this version, the cylinder barrel is driven and, as a result, the pistons which are located and guided in the barrel rotate with it.

Bent Axis Motor

With this type of hydraulic motor, the cylinder barrel is driven by the pistons which in turn are themselves driven by the drive flange.

Wobble-Plate Motor

With this type of hydraulic motor, a so-called wobble plate is driven by the input or drive shaft.

For a more detailed description of each of these motors please visit our "How stuff works" motor series page or contact one of our Hyspecs Engineers 0508 497 732.

Hydraulic Winches

Boat Hydraulics Including Remote Control of the Hydraulic Winches. Hyspecs was contracted by a major North Island boat builder to supply the hydraulics for a 24m catamaran work boat.

See the winches in action on youtube http://www.youtube.com/watch?v=-B-BYu0p9_0 

In order to make this a multi purpose work boat, Hyspecs had to design the hydraulic system to seamlessly run various deck equipment simultaneously.

Log Splitter Parts

Build Your Own Log Splitter With Hyspecs Log Splitter Parts. Hyspecs has a range of log splitter parts to suit a variety of size requirements and performances.

Hyspecs source only quality parts that you can rely on.

The log splitter parts can be sized to suit portable petrol engine units, tractor PTO set-ups and electric motors. When designing your log splitter, take into consideration the throughput you would like to achieve. The more horsepower you have, the faster you will be able to split the wood.

See in action a Hyspecs custom built commercial 30 tonne log splitter with integral conveyor. Hyspecs sales engineers designed the system with a Galtech double gear pump, unloader valve and auto kick out valve. So much easier than weilding an axe!
