Descrição detalhada

This hydraulic pump is equipped with an integrated boost pump, responsible for providing stable boost pressure and pilot oil supply to ensure reliable system control and normal startup operation. When the swashplate passes through the neutral position, the pump can realize smooth switching of flow direction, avoiding impact and pressure fluctuation. It adopts high-pressure relief valves with integrated boost function, and is fitted with independent boost-pressure relief valve to realize overpressure protection and stable pressure regulation. The pump is optionally configured with pressure cut-off function to set limit pressure according to working conditions and protect components from overload damage. Meanwhile, it supports a large variety of control modes, adaptable to different working scenarios and system matching demands, featuring compact structure, stable running and convenient parameter adjustment.

Notice

▶Theoretical values, without efficiency and tolerances;values rounded

▶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.

Determining the operating characteristics

Fluxo qv=(Vg ∙ n ∙ ηv) / 1000 L/min
Torque M=(Vg ∙ Δp) /(20 ∙ π ∙ ηhm) Nm
Energia P=(2π ∙ M ∙ n)/60000=(qv ∙ Δp)/(600 ∙ ηt)  kW

Key

Vg  Displacement per revolution in [cm3]

Δp  Differential pressure [bar]

n   Rotational speed [rpm]

ηv   Volumetric efficiency

ηhm  Hydraulic-mechanical efficiency

ηt   Total efficiency (ηt= ηvhm)

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.
