Green Hydraulic Power Provides up to 70% Energy Savings

MJC Engineering tailors its Spectra hydraulic power system to the application; employs variable speed servo pump drives on standard units in 100-, 200- and 300-gallon tank units rated up to 4,000 PSI

Huntington Beach, California-based MJC Engineering, a longtime U.S. builder of CNC metal spinning, rotary forge and flow forming machines, has announced the development of a new hydraulic power system, termed Green Hydraulic Power. "This system 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% in energy costs to reduce the user's carbon footprint," said a company spokesperson.

Green Hydraulic Power is offered as a value add on to the Spectra Line of hydraulic power units provided on MJC machines and utilizes the Siemens SINAMICS variable speed servo pump drive. "High-demand hydraulic systems on many machine types significantly improve as the result of using this concept from MJC Engineering," said company President Carl Lorentzen. "We saw that the servo pump could control pressure and flow, as they precisely convert electric energy into hydraulic power. In some cases, the use of control valves is partially or completely eliminated, depending on the application."

"Almost all machine tools using hydraulic power are candidates for variable speed servo pump drive technology," said Lorentzen.

"Complete payback on the system is estimated at 12-24 months and the system has the additional benefit of control data output from an onboard diagnostic capability in the drive that supplies information for a predictive maintenance protocol. 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 thereby results in as much as a 70% reduction in onsite servicing," said a company spokesperson.

The Spectra line of hydraulic power units is offered in 100-, 200- and 300-gallon tank units rated up to 4,000 PSI and is available in two styles: one with a VFD, asynchronous motor and internal gear pump; while the second has a servo inverter, synchronous servo motor and internal gear pump.

A full review of Green Hydraulic Power is contained in an informative PowerPoint and literature available from MJC Engineering.
