Модельная серия: The A4FO series is a line of fixed axial piston pumps by Rexroth, recognized for its stable performance and high reliability in the hydraulic field.
Приложение: It is widely used in industrial machinery, Строительное оборудование, agricultural machinery and other fields that require a stable hydraulic power supply. Например, it can be used in metal processing machine tools, вилочные погрузчики, and tractors.
Технические характеристики
Смещение: The displacement of the A4FO series usually ranges from 25 см³/об до 100 см³/об. Different models within the series offer specific displacement values to meet various flow requirements in hydraulic systems.
Номинальное давление
Рейтинг давления: Номинальное давление обычно составляет около 280 бар. This is the pressure at which the pump can continuously operate under normal working conditions to provide the required flow.
Максимальное давление: The maximum pressure that the pump can withstand reaches up to 350 бар на короткое время. This allows the pump to handle sudden pressure surges and high – load situations in the hydraulic system.
Скорость
Рейтинг скорости: The rated speed of the A4FO series pumps is typically between 1500 об/мин и 2000 rpm. Operating at the rated speed ensures optimal performance in terms of flow and pressure output.
Максимальная скорость: The maximum allowable speed is around 2200 rpm. Exceeding this speed may cause increased wear and reduced pump lifespan.
Скорость потока: The flow rate of the A4FO pump depends on its displacement and operating speed. It can be calculated by the formula: Скорость потока (L/мин) = Смещение (см³/об) × Скорость (rpm) / 1000. В практических приложениях, due to internal leakage and other factors, the actual flow rate is about 90% – 95% теоретического значения.
