Hydraulic Power Units are used whereby energy is transmitted, controlled and distributed using pressurised liquid fluid as medium. Modern day applications of hydraulic power units are extremely diverse and are divided into mobile applications (agriculture machinery, diggers, graders, road maintenance vehicle, forklift trucks, excavators etc.), industrial applications (machine tools, food processing machinery, automatic handling and assembly equipment, steel works and mining etc.), and other (automotive, aerospace and marine industry, civil engineering, theatre and leisure, medicine etc.).
Hydraulic Power Units can be designed as open, closed and combined. What makes a hydraulic power unit?
A typical hydraulic power unit may include the following components:
++ pump to convert mechanical power into hydraulic power,
++ cylinders or motors to convert hydraulic power to linear or rotary
mechanical power,
++ valves to control direction, pressure and amount of fluid,
++ filters and regulators which maintain the condition of fluid,
++ hoses, tubes and fittings,
++ reservoirs and accumulators to store the fluid and energy,
++ Instruments to monitor the performance of the hydraulic power unit.
