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).

Manufacturer's specifications on the max. admissible tightening torques of the fittings used are to be observed! For mounting screws according to DIN 13, we recommend checking the tightening torque case by case according to VDI 2230, version 2003.

Installation in MB or MB1 (pump) in connection with electronic version "actual pressure value input F" For attaching an HM20-2X/315-F-C13-0,5 in MB attachment, an adapter from M14x1.5 to G1/4 (mat. no. R900695665) is necessary. Due to the installation position, the HM20 cable version cannot be used for all sizes without restrictions (use with M12 extension cable).

When using an external pressure transducer:

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.

Size 40 to 71

with through-drive shaft, without hub, without intermediate flange, closed by means of a pressure-resistant cover in a fluid-tight way

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 SYHDFEn control system can be found in the operating instructions (See section “Further information about this control system”).
