R902137627 A2FE125/61W-VAL100 Technical data:

Note

• The values in the table are theoretical values, without consideration of efficiencies and tolerances. The values are rounded.
• Exceeding the maximum or falling below the minimum permissible values can lead to a loss of function, a reduction in operational service life or total 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 CONTACT US.

• Speed range

  No limit to minimum speed nmin. If uniformity of motion is required, speed nmin must not be less than 50 rpm.

  2)	Special version, please contact us.
  3)	Equates e.g. with the VG 46 a temperature range of +5 °C to +85 °C (see selection diagram)

  Note

  To reduce high temperature of the hydraulic fluid in the axial piston unit we recommend the use of a flushing and boost pressure valve (see chapter Extended functions and versions).

  Explanatory note regarding the selection of hydraulic fluid

  The hydraulic fluid should be selected such that the operating viscosity in the operating temperature range is within the optimum range (vopt see selection diagram).

  Selection diagram

• 

• Filtration of the hydraulic fluid

  Finer filtration improves the cleanliness level of the hydraulic fluid, which increases the service life of the axial piston unit.

  A cleanliness level of at least 20/18/15 is to be maintained according to ISO 4406.

  At a hydraulic fluid viscosity of less than 10 mm²/s (e.g. due to high temperatures in short-term operation) at the drain port, a cleanliness level of at least 19/17/14 according to ISO 4406 is required.

  For example, the viscosity is 10 mm²/s at:

• HLP 32 a temperature of 73°C
• HLP 46 a temperature of 85°C

• Operating pressure range

  Pressure at working port A or B (high-pressure side)			Definition
  Nominal pressure	pnom	see table of values	The nominal pressure corresponds to the maximum design pressure.
  Maximum pressure	pmax	see table of values	The maximum pressure corresponds to the maximum operating pressure within the single operating period. The sum of the single operating periods must not exceed the total operating period.
  Single operating period		10 s
  Total operating period		300 h
  Minimum pressure	pHP min	25 bar	Minimum pressure on high-pressure side (port A or B) required to prevent damage to the axial piston unit.
  Minimum pressure at inlet (pump operating mode)	pE min	see diagram	To prevent damage to the axial piston motor in pump mode (change of high-pressure side with unchanged direction of rotation, e.g. when braking),a minimum pressure must be guaranteed at the working port (inlet). The minimum pressure depends on the rotational speed and displacement of the axial piston unit.
  Total pressure	pSu	700 bar	The summation pressure is the sum of the pressures at both work ports (A and B).
  Rate of pressure change			Definition
  with integrated pressure relief valve	RA max	9000 bar/s	Maximum permissible rate of pressure build-up and reduction during a pressure change over the entire pressure range.
  without pressure relief valve	RA max	16000 bar/s
  Case pressure at port T			Definition
  Continuous differential pressure	ΔpT cont	2 bar	Maximum averaged differential pressure at the shaft seal (case to ambient)
  Pressure peaks	pT peak	10 bar	t

  Note

• Working pressure range valid when using hydraulic fluids based on mineral oils. Values for other hydraulic fluids, please contact us.

• Minimum pressure at inlet (pump operating mode)

• 

• This diagram is only valid for the optimum viscosity range of vopt = 16 to 36 mm2/s

  Please contact us if these conditions cannot be satisfied.

  Pressure definition

• 

• Note

• The service life of the shaft seal is influenced by the speed of the axial piston unit and the case pressure.
• The service life decreases with an increase of the mean differential pressure between the case and the ambient pressure and with a higher frequency of pressure spikes.
• The case pressure must be equal to or higher than the ambient pressure.
