Modern industrial machinery is creating ever-increasing demands on hydraulics to provide more efficient and quieter solutions with a smaller footprint, while maintaining the benefits traditionally associated with hydraulic systems, i.e., high power density, precise control and enduring performance. But historically, these benefits have come with the high cost of inefficient energy allocation, heat generation and noise. The variety of discreet components constituting each hydraulic system has complicated the challenge.
Knowledge requiredNo two hydraulic systems are identical, and effective integrations require a deep understanding of
- Hydraulic systems
- Hydraulic pumps
- Electric motor technologies
- Control algorithms
– and how these interact with each other.
Conventional hydraulic power units require oversize pumps and motors to ensure performance during a system’s highest duty-cycle demands. When energy costs were predictable and environmental regulations less stringent, the wasted energy and high CO2 emissions were not seen as problematic. In today’s eco-conscious and globally competitive economic environment, a transition to systems in which power is precisely modulated to the requirements of specific tasks within highly complex hydraulic systems is essential.
This is where Drive Controlled Pump (DCP) technology can provide a solution to address the challenges of
- More demanding applications
- Rising energy costs
- Rising staff costs
- Greater environmental requirements
