Description détaillée

This axial piston variable pump adopts a swashplate rotary group structure, professionally designed for open-circuit hydrostatic drive systems and suitable for various industrial hydraulic operation scenarios. It supports a high permissible drive speed, enabling efficient and high-speed operation of the whole equipment to meet high-frequency working demands. Featuring an optimized power-to-weight ratio, the pump boasts compact overall dimensions and lightweight construction, which facilitates flexible installation and equipment integration while saving layout space. It delivers excellent suction performance with low suction resistance and stable oil filling capacity, effectively preventing cavitation and air suction issues to ensure continuous and reliable hydraulic system operation. Equipped with electro-hydraulic pressure control and independent power control functions, the pump can precisely adjust system pressure and output power according to actual load changes, realizing stable operation, reasonable power matching and effective energy consumption reduction.

Determining the operating characteristics

Flux	q_v=(V_g∙ n ∙ η_v) / 1000	L/min
Torque	M=(V_g ∙ Δp) /(20 ∙ π ∙ η_h_m)	Rien
Puissance	P=(2π ∙ M ∙ n)/60000=(q_v∙ Δp)/(600 ∙ η_t)	kW

Key

V_g Displacement per revolution in [cm³]

Δp Differential pressure [bar]

n Rotational speed [rpm]

η_v Volumetric efficiency

η_h_m Hydraulic-mechanical efficiency

η_t Total efficiency (η_t= η_v*η_hm)

¹⁾ The values are applicable:

- At an abs. pressure p_abdos = 1 bar at the suction port S

- for the optimum viscosity range from V_opt = 36 to 16 mm²/s

- with hydraulic fluid on the basis of mineral oils

²⁾See diagram on page 9 at speed increase up to n_{max adm}.

³⁾The data are valid for values between the minimum required and maximum permissible rotational speed. It applies for external stimuli (e.g. diesel engine 2 to 8 times rotary frequency, cardan shaft twice the rotary frequency). The limit value is only valid fora single pump. The load capacity of the connection parts must be considered.
