PROBLEM
MOTOR DOES NOT
RUN
MOTOR RUNS HOT
MOTOR RUNS BUT
PUMP DOES NOT
INJECT OR
INJECTION IS
INFERIOR TO
NOMINAL ONE
PUMP TRICKLES
LIQUID THROUGH
INFERIOR CYLINDER
HOLE
PUMP TRICKLES OIL
THROUGH INFERIOR
CYLINDER HOLE
PUMP LEAKS OIL
THROUGH
CAUSE
THERE IS NO TENSION
MOTOR PROTECTION HAS BLOWN
UP
A PHASE IS FAILING (three-phase);
WRONG INCOMING TENSION
SUPERIOR CONSUME THAN
NOMINAL ONE
LOW WORK FREQUENCY (only with
inverter)
PUMP HAS NOT BEEN PRIMED
SUCTION FILTER IS DIRTY
AIR COMES INTO SUCTION PIPE
CAVITATION IN SUCTION
DAMAGED SEALS
DAMAGED PISTON
DAMAGED BELLOWS
DAMAGED REGULATOR O’RINGS
SUCTION / IMPULSION VALVES ARE
DIRTY OR DAMAGED
SOLUTION
-Check with a voltmeter incoming
tension
. Check with ammeter that current is not
superior than nominal onel
· Check with volmeter tension in motor
terminals
· Check that injection pressure is not
superior to the one specified in the
module
· Check with a volmeter incoming
tension
· Increase working frequency with
inverter
· Prime the pump injecting at zero
pressure
· Clean filter
- Check sealing in connection points
- Increase pipe diameter.
- Reduce suction pipe length.
- Reduce speed through an inverter.
- Use a less viscous liquid.
-· Change seals
-.Change piston
- Change bellows
- Change o’rings
· Check that incoming tension coincides
with motor one (-10% / +10%)
· Clean or change valves
