Innovative Bosch Rexroth Is Celebrated For Its Energy Efficiency

admin — Thu, 10 May 2012 09:11:21 +0000

Rexroth’s innovative variable speed pump range Sytronix, has been shortlisted in the Energy Awards 2011 as a leading energy and cost effective solution.

One of the variable speed pump models in the Sytronix range Rexroth’s innovative Sytronix variable speed pumps have been recognised by the Energy Awards 2011 in its Energy Efficient Product of the Year category.

The Sytronix range provides the best of both worlds – the reliability of powerful hydraulics with the energy efficiency and dynamics of compact electronics and variable speeds. Plus, energy savings of between 30% and 80% provide a rapid return on investment.

Andrew Collins, Machinery Applications and Engineering Sales manager at Bosch Rexroth, said:” In pressure generation, the use of innovative Sytronix speed-variable pump drives offers great potential for saving energy costs and reducing noise pollution. These results are achieved by reducing the speed of the electric motor and thus the power consumption thanks to intelligent frequency converters.

“Having the Sytronix range shortlisted in the Energy Awards 2011 is a great privilege and we’re excited to hear the result in December.”

Rexroth Sytronix comprises of a comprehensive modular system of pumps, controllers and motors as well as software. Depending on the cycle characteristics and configuration, the variable-speed pump drives can reduce energy consumption in the most varied applications by 30 to 80 percent.Further information on Bosch Rexroth can be found at www.boschrexroth.co.uk.

Bosch Rexroth is one of the world’s leading specialists in the field of drive and control technologies.

Due to this fact Rexroth hydraulic product components has always been a preferred choice amongst Neilson Hydraulics customers. Due to this increased demand for genuine Bosch Rexroth hydraulic components, especially in the far east, the ability to maintain constant delivery supplies for the UK market in recent months has been stretched.

Neilson Hydraulics are now delighted to announce that due to increased manufacturing output from Bosch Rexroth along with Neilson Hydraulics being an authorised UK Distributor for Rexroth components, we are now able to better meet the increased demand from clients for these highly sought after components, both at great prices and improved delivery times.

“delivery times of Bosch Rexroth are back on track for 2012”

When Neilson Hydraulics met the Sauer-Danfoss Plus+1 system

When asked to problem solve in the world of hydraulics it pays to only use the best hydraulic components.

CONSTANT PRESSURE – SPRAY CONTROL

Design Brief:
To replace manual control of nozzle pressure (bitumen) when the spray bar length (number of nozzles) is varied to compensate for varying road width.

The Solutions:

As the road width varies, spray bars are extended and retracted. This in turn requires the hydraulic motor driving the bitumen pump to vary the speed in order to maintain a constant pressure and hence flow at each of the spray nozzles.

Neilson designed and supplied a simple Sauer-Danfoss Plus+1 system, which maintained the liquid (bitumen) pressure within +/–

1 psi (at the nozzles) irrespective of the number of nozzles in operation.

The operator selects the required target nozzle pressure and the Sauer-Danfoss Plus+1 system is programmed to constantly compare target to actual pressure from the pressure sensor in the bitumen and adjusts the hydraulic motor speed accordingly.

An additional option would be to link the Plus+1 system to the truck’s Canbus system and vary the nozzle flow with the road speed.

Neilson Hydraulics are more than suppliers of hydraulic components, Neilson are Hydraulic Engineers, with the experience and technical expertise to design and build hydraulic solutions for any type of hydraulics problem. Using only the best components available such as Sauer Danfoss and Bosch Rexroth, Neilson not only supply a design solution that works, but one that lasts!!!

Sauer-Danfoss Launches New 20 cm³ Direct Displacement Control (DDC) Pump

Best-in-class efficiency, compact design and wide range of options make DDC20 the flexible, low-noise solution for wide array of small equipment

OSAKA, Japan, December 2, 2011 – Sauer-Danfoss Inc. (NYSE:SHS). Sauer-Danfoss is pleased to introduce the DDC20 — a new 20 cm³ direct displacement control pump — to their lineup of pumps and motors for transmissions on mobile equipment. As the most compact pump on the market, the DDC20 offers unparalleled efficiency, low noise and the flexibility to perform in a wide array of light-duty equipment applications.

“We developed the DDC20 pump to be one of the most versatile and well-balanced compact pumps on the market,” said Toshihiro Naruse, Product Marketing Manager for Sauer-Danfoss. “With its expanded functionality, excellent total efficiency, low noise and easy installation, we believe the DDC20 is a significant contribution to overall vehicle design.” The DDC20 pump can be applied with most Sauer-Danfoss low speed high torque motors as well as axial piston motors such as Series 40 and LK motors.

Compact Design

At 183.5 mm, the DDC20 has the shortest length of any comparable pump on the market, simplifying circuit design and allowing for easy installation in even the most space-constrained OEM equipment. The DDC20 ensures ample room around the pump, which is typically the most significant design restriction many engineers face when developing compact machines.

“Today’s engine compartments are filled with more components than ever before, making compact design a must,” said Toshihiro. “The DDC20 is not only the most compact pump on the market, but also has the highest power density on the market, making it well-suited for everything from zero-turn mowers, small rollers, sweepers, utility vehicles, sprayers, trenchers, compact tractors and more.”

Best-in-Class Efficiency

The DDC20 boasts best-in-class efficiency without compromising performance. Its male slipper design reduces friction on both the piston and the bore of the cylinder block, which works to reduce oil temperature, improve fuel efficiency and extend oil life, resulting in better overall efficiency.

“As we listen to our OEM customers, efficiency always seems to be at the forefront of their minds, because it equates to overall productivity of their equipment,” said Toshihiro. “We took that sentiment back to our product development team, and they designed the most efficient compact pump on the market.”

Lower Noise and Vibration

Through simulation analysis, Sauer-Danfoss has optimized the valve plate design of the DDC20 in order to reduce noise to 78.5 dBa while operating at 200 bar, 2000 rpm — a level equivalent to the Sauer-Danfoss LPV25 pump, which boasts best-in-class noise reduction. The DDC20 is also designed with a journal bearing in the trunnion, which helps to reduce operating vibration and ensure comfortable human-machine interface.

“Transmissions are typically installed directly below where an operator is sitting, so noise and vibration can often be a big disturbance, impeding productivity,” said Toshihiro. “The journal bearings on the DDC20 help to reduce resonance between the redesigned valve plate and the linkage to the vehicle, which results in quiet operation and lower vibration, keeping the operator comfortable and productive.”

Wide Range of Options

The DDC20 is available with a wide range of options, including various high pressure relief valves, providing OEM vehicle designers the flexibility to use it with an array of motor combinations. With an optional auxiliary pad, the DDC20 also accommodates future conversions and additional components.

The available loop flushing and bypass valves promote ease of use and reliability, allowing a machine or load to be moved without rotating the pump shaft or engine. Additionally, the valves ensure long oil life, satisfying the higher cooling demands and the challenging contamination levels of today’s equipment.

“The DDC20 is meant to stimulate the imaginations of equipment designers while simplifying the installation and integration process,” said Toshihiro. “Its wide range of options coupled with its compact size and power density ensure it can be incorporated into any design, while providing the performance end users demand.”
