QLS-Beispiel
Determine the cause of the blockage as described in the
following e xample and eliminate it.
Â
Let the pu mp run (refe r to ”trigger additional opera ting cy-
cles”, fig. 13-2).
Â
Disconnect a ll feed lines D (fig. 15-1) of the meterin g device
one after the othe r. If oil shows un der pressure the block-
age is located in the line of outlet 3 or in the connected
bearing po in t.
Â
Pump through the blocked line or b earing point using a
hand pump.

NOTE
To check the individual outlet s, leave all
out lets disconnected for a while, since only
one piston stroke is executed with each
mot or re volution. Several strokes are re-
quired fo r a full cycle of all metering d evice s.
Â
Check pressure relief valve (se e chapte r „Operation“) Re-
place it, if necessary.

Replace the mete ring device or clean it as follows:
- Re move a ll threade d tube fit ting s.
- Un screw the piston closure plugs.
- Re move th e piston, if possible, wit h a soft mandrel
(smalle r than Ø 6 mm, 0 .24 in).

IMPORTANT
The piston s a re individually fit in th e bores of
th e metering device. After remo ving the pis-
to ns, mark them in order to reinstall the m in
th e right direction and position. They ma y not
be in tercha nged.
- Tho roughly clean the metering device body in a grease-
dissolving dete rgent and dry it with compressed air.
- Clean through the mate rial passages (Ø 1.5 mm, 0.59 in )
at the t hread ends of the piston bores using a pin.
- Clean the metering device once more and dry it thor-
oughly.
- Re assemble the mete ring de vice .
