Admissible load ‒ determination of nominal load and minimum speed

1)	At SYHDFEN, the minimum speed can be determined by means of the derating function.

Example 1:

A4VSO125 may be operated at ν = 16 mm2/s

as of n = 1328 rpm with nominal load

Example 2:

the admissible load for A4VSO250

is n = 500 rpm and 10 mm2/s

x = 10/25*500/550 = 0.364 (= 127 bar at Vgmax)

Bearing flushing

With the following operating conditions, bearing flushing is necessary for safe continuous operation:

Applications with special fluids (not mineral fluids) due to limited lubricity and tight operating temperature range Operation with boundary conditions of temperature and viscosity with mineral oil operation

With vertical installation (drive shaft upwards), bearing flushing is recommended for lubrication of the front bearing and the shaft seal ring.

The bearing is flushed using port "U" in the area of the front flange of the variable displacement pump. The flushing fluid flows through the front bearing and exits with the pump leakage at the leakage connection.

For the individual sizes, the following flushing quantities are recommended:

Size			40	71	125	180	250	355
recommended flushing quantity	qSp	l/min	3	4	5	7	10	15

The specified flushing quantities result in a pressure differential between port "U” (including fitting) and the leakage chamber of approx. 2 bar (series 1) and approx. 3 bar (series 3).

When using the external bearing flushing, the throttle screw in port U has to be screwed-in to the stop.

Leakage pressure

The admissible leakage pressure (housing pressure) depends on the speed (see diagram).

Max. leakage pressure (housing pressure)

pL abs max = 4 bar absolute

These specifications are guidelines; under special operating conditions, a limitation may become necessary.

Notes:

The specified values are only valid when using the system-related components specified in this data sheet. At pressures < 20 bar, higher tolerances have to be anticipated due to lower actuating forces.

Installation in the B line (preferably close to the actuator) and electrical connection via the central connection X1. Explanation in the operating instructions.

Important notes on external supply:

In the case of an actuating system with external supply, the pump adjustment will - in case of voltage failure - not switch to zero stroke but to the negative stop (displacement of 100 % flow from the system to the tank). With an active fault message, it is imperative that the machine control reacts (e. g. switching off the drive motor of the pump, interrupting the external supply of the actuating system). The command values for pressure and flow must always be greater than zero (pcommand ≥ 3 bar, αcommand ≥ 5 %) as due to drift or tolerances, there is no exact "zero" pressure or "zero" swivel angle. Under unfavorable conditions, smaller command value presettings can lead to cavitation. The actual pressure value must not be less than 10 bar for more than 10 minutes (lubrication).

Through-drive "K99"

The control systems of size 40 to 71 are partly supplied with through-drive K99.

Their advantage is that the through-drive can be subsequently modified. By simply exchanging the intermediate flange and the hub, the through-drive can be adjusted to the on-site requirements.

The assemblies as exchange kits can be ordered separately, see "Accessories for through-drives" as well as data sheet 95581.

Small centering diameters are directly worked into the pump subplate. Subsequent modification is not possible. Please note the type key under ordering code and the overview under "Accessories for through-drives". Hubs for through-drives can be ordered separately.

Command values may only be switched via relays with gold-plated contacts (low voltage, low currents) Always shield command and actual value cables. The distance to aerial lines or radios must be at least 1 m. Do not lay signal lines close to power lines. Amending notes on the SYHDFE control system can be found in the operating instructions (See section “Further information about this control system”).
