Description détaillée

The A2FO is a fixed displacement pump featuring an axial piston, bent axis design, specifically engineered for hydrostatic drives in open-circuit systems. Its bent axis structure ensures efficient power transmission and stable oil flow output, which is critical for the reliable operation of open-circuit hydrostatic drive systems in various scenarios. This pump is widely applicable to both mobile and industrial applications, including construction machinery, agricultural equipment, industrial hydraulic stations, and other equipment that requires stable hydraulic power supply, adapting well to different working environments and load conditions. The output flow of the A2FO pump is strictly proportional to the drive speed and displacement, meaning the flow can be predictably adjusted by changing the drive speed, ensuring consistent performance that matches the actual working demands of the system. Its drive shaft bearings are specially designed and optimized to meet the service life requirements of mobile and industrial operation areas, with strong wear resistance and load-bearing capacity to reduce maintenance frequency. Additionally, the pump boasts high power density, integrating powerful hydraulic output into a compact structure, which saves installation space while delivering reliable and efficient power, making it an ideal choice for equipment with limited installation space and high power requirements.

1)the values shown are valid for an absolute pressure(P_abdos)of 0.1 MPa at suction inlet S and when operated on mineral oil (with a specific mass of 0.88kg/L)

2)by increase of the input pressure (P_a_b_s>0.1 MPa) the rotational speeds can beincreased to the max. admissible speeds n_{max limit} (speed limits)(see diagram page 99)

Determining the size

Torque	T=(V_g ∙ Δp) / 20 ∙ π ∙ η_hm	Rien
Puissance	P=(2π ∙ T ∙ n)/60000=(q_v∙ Δp)/600 ∙ η_t	kW

V_g = Displacement per revolution in mL/r

Δp = =Differential pressure in MPa

n = Speed in rpm

η_v= Volumetric efficiency

η_hm = Mechanical-hydraulic efficiency

η_t = Efficacité globale
