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