Test procedure
Use a test stand that supplies
a ow of about 30 l/min. and
pressures of up to 300 bar.
A secondary ow of 3-5
l/min. at a pressure of 25
bar is required to supply
low pressure for externally
supplied controls.
EP control requires an
amplier supplying correct
current according to
specication.
Test
1. Fill housing with hydraulic
uid and start the pump in the
test stand.
2. Increase the pressure
with the restrictor valve on
the return line. Max allowed
pressure is 150 bar / 2150 psi.
3. Check the drain ow and
compare with the table.
V12-60, -80 V12-110, -160
3.0 4.0
För funktionskontroll behövs
en provbänk med kapacitet
30l/min och 300 bar. Ett
sekundäröde på 3-5 l/min
och tryck 25 bar krävs för
ställdon med extern matning.
EP ställdon kräver en
förstärkare.
Test
1. Fyll V12 med olja i
huset och starta pumpen i
testbänken.
2. Öka trycket med stryp-
ventilen på returledningen.
Trycket får inte överstiga
150 bar / 2150 psi.
3. Mät läcködet och
kontrollera mot tabellen
