Serie de modelos: 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.
Solicitud: Es ampliamente utilizado en maquinaria industrial., equipo de construcción, agricultural machinery and other fields that require a stable hydraulic power supply. Por ejemplo, it can be used in metal processing machine tools, montacargas, and tractors.
Especificaciones de rendimiento
Desplazamiento: The displacement of the A4FO series usually ranges from 25 cm³/rev a 100 cm³/rev. Different models within the series offer specific displacement values to meet various flow requirements in hydraulic systems.
Clasificaciones de presión
Presión nominal: La presión nominal generalmente es de aproximadamente 280 bar. This is the pressure at which the pump can continuously operate under normal working conditions to provide the required flow.
Máxima presión: The maximum pressure that the pump can withstand reaches up to 350 bar for a short time. This allows the pump to handle sudden pressure surges and high – load situations in the hydraulic system.
Velocidad
Velocidad nominal: The rated speed of the A4FO series pumps is typically between 1500 rpm y 2000 rpm. Operating at the rated speed ensures optimal performance in terms of flow and pressure output.
Velocidad máxima: La velocidad máxima permitida es de aproximadamente 2200 rpm. Exceeding this speed may cause increased wear and reduced pump lifespan.
Tasa de flujo: The flow rate of the A4FO pump depends on its displacement and operating speed. It can be calculated by the formula: Caudal (L/min) = Desplazamiento (cm³/rev) × Velocidad (rpm) / 1000. In practical applications, due to internal leakage and other factors, the actual flow rate is about 90% – 95% del valor teórico.
