How to Achieve Huge Energy Savings on Hydraulic Systems

In Booth A-1756, MJC Engineering & Technology, Inc. (Huntington Beach, CA), a builder of CNC metal spinning, rotary forge and flow-forming machines for the automotive, aerospace and wheel industries, will showcase Green Hydraulic Power®, a new hydraulic power system offered as standard on the hydraulic power units in MJC machine builds that provides higher machine yield, reduces noise emissions by 20 dBA, generates less heat, produces a shorter cycle time on various machine types and involves less oil volume, all resulting in a system that saves up to 70 percent in energy costs to reduce the user’s carbon footprint. This unit is now offered for OEM integration by other machine builders. Green Hydraulic Power utilizes components by Parker, Siemens and ABB, and high demand hydraulic systems on many machine types significantly improve by using this system.

“We saw how the servo pump could control pressure and flow, as they precisely convert electric energy nto hydraulic power,” explained Carl Lorentzen, the president of MJC Engineering. “In some cases, the use of control valves is partially or completely eliminated, depending on the application. We quickly realized our development could be utilized on many other types of machinery as an OEM component. We have already generated substantial new business for the unit and know we are onto something big.” MJC subsequently developed a subsidiary unit, Green Hydraulic Power, Inc., with a separate sales force for the unit’s development in the market. “The applications are many for this new system concept,” added Lorentzen, “because almost all machine tools use hydraulic power, making them candidates for variable-speed servo pump drive technology. Injection presses, materials handling equipment, stamping presses, other metal forming machines and more can utilize Green Hydraulic Power.”

Complete payback on the system is estimated at 12 to 24 months, with the additional benefit of control data output from the onboard diagnostic capability in the drive that supplies information for a predictive maintenance protocol in an Industry 4.0 scenario. The basics of pressure, temperature and acceleration data measurement are standard, with additional data outputs on oil level, filter condition, running efficiency and other parameters available. The servo pump results in as much as a 70 percent reduction in onsite servicing, according to the manufacturer. This new line is offered in 100 gal, 200 gal and 300 gal tank units rated up to 3,000 psi and available in two styles: one with a VFD, asynchronous motor and internal gear pump, the other with a servo inverter, synchronous servo motor, and internal gear pump. Green Hydraulic Power, Inc. has been working closely with local power utility companies to develop technology specific solution codes that enable end-users to qualify for incentive programs. Custom incentive programs are available where standard incentive programs have not yet been established.
