Study of Energy and Demand Savings on a High Efficiency Hydraulic Pump System with Infinite Turn Down Technology (ITDT)
Abstract
Detailed field measurement and verification of
electrical energy (kWh) and demand (kW)
savings is conducted on an injection molding
machine used in typical plastic manufacturing
facility retrofitted with a high efficiency
hydraulic pump system. Significant energy
usage and demand savings are verified for the
retrofitted injection molding machine. The
savings are realized by electronically attenuating
the torque of a positive displacement pump
irrespective of the volumetric flow required by
the cycle. With help of a power analyzer, power
quality issues are addressed. Some voltage
distortion was observed due to the harmonic
currents introduced by the control algorithm of
the high efficiency hydraulic system. A
comparative study of electrical energy and
demand savings between an injection molding
machine retrofitted with the high efficiency
hydraulic pump system or variable frequency
drive will also be presented.
