- INCORRECT DISC SIZE
- TOO HIGH FUEL OIL TEMPERATURE
- TOO MUCH FEED RATE
- TOO MUCH SLUDGE I SIDE THE BOWEL
- LOW RPM OF THE BOWL
- SEALING WATER FAILURE
- OPERATING WATER FAILURE
- MAIN SEALING RING WORN OUT.
WHAT ARE THE REASON FOR VIBRATION ON PURIFIER?
- TOO MUCH SLUDGE
- BEARING FAILURE
- FAILURE OF FOUNDATION BOLT
- GEAR WORN OUT
- UNEVEN TOUCHING WITH FRICTION CLUTCH
- MOTOR SPEED IS TOO LOW OE TOO HIGH.
WHY WE ARE NOT GETTING ENOUGH RPM WHEN PURIFIER IS RUNNING?
- IMPROPER TOUCHING WITH FRICTION CLUTCH
- TOUCHING WITH BREAK
- EXCESSIVE SLUDGE IN SIDE THE PURIFIER
- BEARING FAILURE
- ONE PHASE POWER FAILURE
- MOTOR RUNNING OVERSPEED.
SURVIVER WILL ASK YOU GOW TO CHANGE THE PURIFIER HFO TO DO?
- REPLACE THE GRAVITY DISC
- (WHICH IS SMALLER THAN HEAVY OIL)
- OPEN HEATER BYPASS VALVE
- CLOSE THE HFO HEATER'S IN AND OUT VALVE
- AND OPEN THE DRAIN VALVE OF HEATER.
(SOME PURIFIER DESIGN ONLY FOR DO WHICH WILL NOT CHANGEOVER TO HFO.)
HOW WILL YOU ADJUST PURIFIER BOWEL HEIGHT?
- FOR SMALL VARIATION ADJUST THE VERTICAL SHAFT ADJUSTING SCREW
(SURVIVER MAY ASK WHAT HAPPENED IF REDUCE PURIFIER BOWEL HEIGHT)
ANSWER IS - OIL GO WITH WATER OUTLET.
HOW WILL YOU SELECT THE GRAVITY DISC?
- MONOGRAM METHOD
- TRIALS AND ERROR METHOD
MONOGRAM METHOD ?
THERE WILL BE A CHART ( LIKE ABOVE I MENTIONED.) USING THIS CHART WE CAN FIND THE GRAVITY DISC SIZE BY USING SOME PARAMETERS
- SPECIFIC GRAVITY
- SEPARATION OF TEMPERATURE
- FEED RATE M3/HOURS OR LITTERS/HOURS
- GRAVITY DISC SIZE
TRAIL AND ERROR METHOD?
- FIRST PUT THE LARGE DISC AND CHECK OIL IS OVERFLOWING OR NOT .. IF OVERFLOWING. PUT SMALL ONE. LIKE THIS WE WILL SELECT THE GRAVITY DISC
WHAT HAPPENED IF GRAVITY DISC DIAMETER IS TOO HIGH?
- WATER WILL GO THROUGH WITH OIL
WHAT HAPPENED IF DIAMETER OF GRAVITY DISC SIZE IS TOO SMALL?
- WE WILL GET THE PURE OIL BUT SOME MORE GOOD OIL WILL GO WITH SLUDGE.
NOTES:
DENSITY OF OIL IS INCREASE - DECREASE THE DIAMETER OF DISC
DENSITY OF OIL IS DECREASE- INCREASE THE DIAMETER OF DISC.
WHAT IS PARING DISC?
- IT IS A STATIONARY IMPELLER MOUNTED ON THE NECK OF THE BOWL
- FUNCTION OF THE PARING DISC IS CONVERT THE ROTATIONAL ENERGY INTO PRESSURE ENERGY.
WHAT IS FRICTIONAL CLUTCH?
- TO GRADUALLY INCREASE THE RPM OF RGE PURIFIER
- TO PREVENT THE STARTING OVER CURRENT OF MOTOR .
WHERE IS PILOT VALVE IS LOCATED IN PURIFIER?
- BOWL OPENING AND CLOSING WILL BE DONE BY PILOT VALVE
WHAT IS BLIND DISC ?
- THE DISC HAVE NO HOLES, ITS USED TO CONVERT THE PURIFIER INTO CLARIFIER.
HOW BACK PRESSURE IS MAINTAINED?
- USING BACK PRESSURE VALVE
WHY BACK PRESSURE IS MAINTAINED?
- IF WE WILL NOT MAINTAIN BACK PRESSURE PURIFIER IS ACT LIKE A CENTRIFUGAL PUMP.
WHAT IS THROUGH PUT?
- FEED RATE IS CALLED THROUGH PUT (OIL WHICH GIVEN TO PURIFIER FOR PURIFICATION)
WHAT IS WEAK LINK? WHERE ITS LOCATED?
- WEAK LINK IS PROVIDED BETWEEN MOTOR AND HORIZONTAL SHAFT TO BREAK THE LINK IN CASE OF MOTOR OVERLOAD. TO AVOID THE DAMAGE OF GEAR AND SHAFT .
