Aviso

▶Valores teóricos, sin eficiencia ni tolerancias; valores redondeados

▶Operation above the maximum values or below the minimum values may result in a loss of function,a reduced service life or in the destruction of the axial piston unit. Prance recommends testing the loads by means of experiment or calculation /simulation and comparison with the permissible values.

Determinación de las características de funcionamiento

Flujo	qv=(Vg ∙ n ∙ ηv) / 1000	l/min
Par de torsión	M=(Vg ∙ Δp) /(20 ∙ π ∙ ηhm)	Nm
Poder	P=(2π ∙ M ∙ n)/60000=(qv ∙ Δp)/(600 ∙ ηt)	kW

Clave

V_g  Cilindrada por revolución en [cm³]

Δp Presión diferencial [bar]

n   Velocidad de giro [rpm]

η_v   Eficiencia volumétrica

η_hm  Rendimiento hidráulico-mecánico

η_t   Eficiencia total (η_t= η_v*η_hm)

1)The values are applicable:

- for the optimum viscosity range from Vopt = 36 ... 16 mm²/s

- for hydraulic fluid based on mineral oils (for HF hydraulic fluids,observe the technical data in 90225)

2)Valid at half corner power (e.g. at Vg max and pi/2)

3) Valid at Ap = 70 ... 150 bar or Ap < 300 bar and t < 0.1 s

4)Without boost pump

5)The data are valid for values between the minimum required and maximum permissible rotational speed.

Valid for external excitation (e. g. diesel engine 2 to 8 times rotary frequency; cardan shaft twice the rotary frequency).

The limit value is only valid for a single pump.

The load capacity of the connection parts must be considered.

6)Weight may vary by equipment.
