وصف تفصيلي

This hydraulic pump is equipped with a robust motor, which is constructed with high-strength materials and optimized structural design to resist wear, impact and high-temperature effects, ensuring a long service life even in harsh working environments such as mobile machinery and industrial stations, reducing maintenance costs and downtime. The motor is approved for very high rotational speeds, enabling stable and reliable operation at extreme high-speed conditions without excessive vibration, noise or component damage, which is essential for high-efficiency hydraulic drive systems requiring rapid power transmission. It boasts a high control range and can be swiveled to zero displacement, allowing flexible adjustment of output flow from maximum to zero, realizing precise control of the hydraulic system and avoiding energy waste caused by redundant flow. It offers a variety of control options to meet different system control needs, and can be optionally equipped with a mounted flushing and boost-pressure valve to enhance oil cleanliness and maintain stable boost pressure, improving system reliability. Additionally, it can be optionally configured with an integrated or mounted counterbalance valve to prevent load drift and ensure safe and stable operation of the system. Adopting a bent-axis design, it optimizes power transmission efficiency, reduces internal mechanical wear, and maintains a compact structure while enhancing overall operational stability.

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. Other permissible limit values, such as speed variation, reduced angular acceleration as a function of the frequency and the permissible angular acceleration at start (lower than the maximum angular acceleration) can be found in data sheet 90261.

1) The minimum and maximum displacement can be steplessly varied,see Ordering code on page 2. (Standard setting size 250 if not Specified when ordering: Vgmin = 0.2×Vg الحد الأقصى, Vg الحد الأقصى = Vg الحد الأقصى).

2) The values are applicable:

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

- with hydraulic fluid based on mineral oils

Effect of radial force Fq on bearing service life

By selecting a suitable direction of radial force Fq, the load on the bearings, caused by the internal rotary group forces can be reduced, thus optimizing the bearing service life.Recommended position of mating gear is dependent on the direction of rotation. Examples:

▼Gear output drive

1 "Counter-clockwise" rotational direction, pressure at port B

2 "Clockwise" rotational direction, pressure at port A

3 Bidirectional direction of rotation

Notice

▶The values given are maximum values and do not apply

to continuous operation.

▶The permissible axial force in direction -Fax is to be avoided as the bearing service life is reduced.

▶Special requirements apply in the case of belt output drives. Please contact us.

2)When at standstill or when axial piston unit working in depressurized conditions. Higher forces are permissible under pressure, please contact us.
