Test Your Skills Competition Result

Thank you to all of those who entered the Hyspecs "Test Your Skills" competition. We had heaps of correct entries but there can only be one winner...

Congratulations to our winner Ross Shultz from Active Engineering Solutions Ltd.

Answer : The new pump was installed with the pressure compensator at the factory setting, which was higher than the system relief valve setting. Whenever the directional control valve is in the centre position full pump flow is relieving across the system relief valve. Depending on the duty cycle of the cylinder this can cause rapid heating of the oil as most of the electric motor power is going into heat.

Stay tuned as we may have another competition in the very near future!

Test Your Skills Competition

A pressure compensated piston pump was leaking excessively after many years of service and a replacement was ordered. Before fitting the new pump the oil and filter element was replaced and existing valves were checked for correct settings. The new pump was started up and it was confirmed to be producing sufficient pressure and the cylinder was cycled a few times before shutting down the powerpack. The next day production started and the hydraulic system overheated after 30 minutes of operation - why?

Send us your answer by 30th July 2015, to be in the draw for a Stanley Thermos flask. All entries qualify (Hyspecs Staff excluded). Answer will be published next Hydrafile. Click here to email us your answer.

Energy Saving Tip: Oil Viscosity Grade

Clean hydraulic oil of the correct viscosity grade and running at optimum temperature will ensure your hydraulics work efficiently. The working viscosity range for most hydraulic systems is 15 to 100 cSt with 20 to 40 cSt being the optimum. For hydraulic oil we generally use the ISO Viscosity Grade classification which is the kinematic viscosity of the oil at 40'C. For lower working temperatures ISO VG 22 or 32 oil is recommended and for higher working temperatures ISO VG 46 or 68 oil is ideal. Hydraulic oil that's too viscous requires extra power to overcome pressure losses, oil that's too thin causes premature wear and excessive internal leakage.

For further advice speak to a Hyspecs Engineer on 0508 497 732.

Hydraulic Oil Testing Kits

Castrol oil sample analysis kits are available from Hyspecs.

The $72 + GST list price of the kit includes postage to Castrol Christchurch and the test cost. Castrol offer a 24 hour turn around on the sample and results can be e-mailed directly to you.

Hytech - Design Doubled

Hyspecs manufacturing division, Hytech have doubled their design capabilities, and reduced their lead times.

Hytech welcomes to the team - Wendy Roberts - CAD Manifold Design Engineer.

Due to increased demand for Hydraulic manifolds, Hytech recruited Wendy as an additional designer to assist Steven Zhou with manifold designs at Hytech.

Wendy has been designing manifolds for 19 years since graduating from Coventry University in the UK with a bachelor of Mechanical Engineering. Wendy worked for UK based family business Integrated Hydraulics for 15 years (this business was bought out by Eaton), she then moved on to Hydraforce (UK) for 4 years before joining Hytech April 2015.

Hytech have been looking for ways to reduce turnaround for the manufacture of their Hydraulic Manifolds. 

This review has involved

  • Matching jobs with similar settings to reduce setting times
  • Tracking setting times
  • Tracking machine hours
  • Looking at the features of the CNC machines to get the most out of these machine
  • Repeat orders can now be managed much more quickly
  • Improved finishing with Nicol plating on all manifolds. The thickness of the plating customised to suit different working environments for longer life.
  • Working towards ISO 9000 acreditation to ensure consistency and quality of products

The results of this continual review process have been

  • Improved turn around in design
  • Increased machine time
  • Improved turn around in production

Mobile Hydraulic Service Centre

Taupo Trailer Montage Web

Hyspecs is pleased to announce the arrival of the Mobile Hydraulic Service Centre otherwise known as "The Service Trailer". 

Based in Taupo this trailer is available to carry out Hydraulic Servicing and repairs at our customers sites. This means that equipment and plant has less downtime during maintenance and repairs.

Hyspecs purchased a trailer, the Hyspecs Chirstchurch service team set out to convert this trailer into a workshop. Johan from Hyspecs Taupo then took over with Ross to put in a Hydraulic Test bench, a Hose press, Welder, Compressor and parts storage. This trailer obviously can not have everything but will be able to help in a number of situations.

As this trailer is mobile we can use this anywhere in the country that is accessible by road should it be required. The trailer has already been used for a number of jobs and with bookings for planned service work. Customers have found this to be a very convenient service. Please call Hyspecs to find out more 0508 497 732 

When Should You Change A Filter?

OMT Tank Top ReturnSpin OnAFilters should be checked at least once a month and elements changed as per the indicators, or every 2000 hours of operation, or every 6 months whichever comes first. Fluid condition should be checked at regular intervals to maintain optimum component life.

Most hydraulic failures and premature wear of components are due to oil contamination.

Hydraulic systems subject to severe service cycles, very high pressures, extreme temperatures or containing piston pumps, proportional and servo valves are more contaminant sensitive and require finer filter media. Hyspecs recommends all filters have visual or electrical pressure differential indicators fitted so you know when to replace the filter elements. An oil particle analysis to ISO 4406 is the best way to determine your filtration effectiveness and the health of the hydraulic system. Hyspecs has oil sample kits available as well as optical oil particle monitors that can be permanently installed on your machine and interfaced with your control system.

Call us here at Hyspecs now for filters or book a service on 0508 497 732.

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

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.
