Introduction to hydraulic groups

Hydraulic groups are integrated assemblies that provide hydraulic power to systems and machines through the generation, regulation and distribution of pressurized fluid. These systems are essential for converting mechanical or electrical energy into hydraulic energy, allowing the movement and control of machinery in various industrial and construction sectors.

A hydraulic group typically comprises a hydraulic pump, a motor or drive, a fluid reservoir, control valves and accessories that ensure efficient and safe operation. Their versatility and robustness make them indispensable in applications that require strength and precision in movement control.

hydraulic pump

The hydraulic pump is the heart of the hydraulic group, responsible for transforming mechanical energy into hydraulic energy by generating a continuous flow of pressurized fluid. There are several types of pumps, such as gear, vane and piston pumps, each adapted to different flow and pressure needs.

Gear pumps are the most common due to their simplicity and low cost, but offer lower efficiency compared to piston pumps, which allow higher pressures and greater performance. Selection of the appropriate pump depends on the specific application, fluid type and working conditions.

The design and quality of the pump directly influence the stability and duration of the hydraulic group, so it is essential to have high precision components and materials resistant to abrasion and corrosion.

Hydraulic fluid reservoir or tank

The reservoir is the container that stores the hydraulic fluid, playing a crucial role in thermal regulation, contamination and continuous supply to the system. In addition, it allows the separation of air and contaminants through integrated filtering systems, ensuring fluid quality.

The tank design must ensure sufficient capacity to dissipate the heat generated, prevent foaming and facilitate access for maintenance and recharging. Common materials are steel, aluminum or reinforced plastics, selected according to the required chemical and mechanical resistance.
