HPW - HIGH PRESSURE WATER PUMPS
TROUBLESHOOTING
5.1
Adjust the hydraulic pressure up as much as
necessary to enable proper operation of
water pressure unloader valve.
Note that the maximum hydraulic pressure
should not be overrun !
If boosting the hydraulic pressure is not
possible, the water unloader pressure setting
should be dropped.
5.2
Repair or replace water pressure unloader
valve.
6.1
Check the tightness of component mating,
tighten screws.
Replace when necessary sealings of pump's
mated surfaces.
Check and tighten/replace couplings.
6.2
Check the tightness of component mating,
tighten screws.
Replace when necessary sealings of pump's
mated surfaces.
Check and tighten/replace couplings.
6.3
If the draining from leakage detectors exceeds
rate of 10 drops per minute, pump's sealings
should be replaced.
The rule applies to dropping of hydraulic fluid,
pumping fluid and their commixture.
