                                • 风力涡轮机液压音高控制系统和制动器

                                  Hydraulic pitch control constantly adjusts the angle of the blades to the wind to optimize the wind turbine’s energy production. Also hydraulic pitch systems act as a main brake in extreme weather or wind conditions protecting the high value turbine.

                                  活塞蓄能器在液压音高系统中起着至关重要的作用。通常它们执行三个功能：
                                  • Damping pulsations from the pump and the proportional valve
                                  • 在紧急停止期间，累加器向圆柱体提供额外的油/能量，将刀片倾斜到安全位置

                                  The wind turbine industry tends to use either bladder or piston accumulators. However there are strong factors suggesting the superiority of piston accumulators in wind turbine applications such as:
                                  • 多次降低气体渗透
                                  • Superior reliability
                                  • 活塞蓄能器的故障不是突然的
                                  • High and low temperature tolerances

                                • SOLAR PANEL MOVEMENT

                                  In concentrated photovoltaic (CPV) systems tracking the sun all day is key for system efficiency. In remote locations high reliability with minimum maintenance is one of the key demands for hydraulic systems. Proven Hydroll accumulators are built for this purpose. Hydroll has recently developed a high pressure accumulator to better serve the needs of our customers in the solar sector.
