11-
THE COMPRESSOR OPERATES HOTTER THEN NORMAL
1- OIL LEVEL IS LOW
CHECK THE OIL LEVEL AND FILL IF NECESARRY
2- THE AMBIENT TEMPERATURE IS HIGH
CHECK THE AMBIENT TEMPERATURE
3- VENTILATION IS INSUFICIENT
THE HOT AIR OUTLET CAN NOT BE DISCHARGED OUT OF COMPRESSOR ROOM HEALTHILY.
THE COOLER MAY BE DIRECTLY SUBJECT TO SUN LIGHT AND THERE MAY BE STRONG WIND
OPPOSITE TO THE HOT AIR OUTLET. CHECK AND TAKE NECESSARY PRECAUTIONS.
4- COMPRESSOR COOLER CELLS OR FAN IMPELLERS ARE CLOGGED / DIRTY
CHECK AND CLEAN
5- THE INTAKE FILTER IS CLOGGED
CHECK AND CLEAN.
6- THE BELTS ARE LOOSE.
CHECK THE TENSION OF BELTS. IT IS EASY TO UNDERSTAND THAT THE BELTS IS LOOSE BY
LOOKING AT THE MOVEMENT OF BELT WHEN THE COMPRESSOR IS RUNNING. PROPERLY
ADJUSTED BELTS ARE NOT BEATS. STRAIN THE BELTS BY CHECKING ITEMS AT "BELT
REPLACEMENT AND ALIGNMENT" SECTION OR INFORM THE SERVICE.
ALSO BELTS MAY BE OILY. IN THIS CASE WHEN THE PRESSURE INCREASES, THE OILY BELTS
MAY BE SLIP. HIGHLY NOISE IS HEARD AND SMOKE IS OBSERVED. CLEAN THE PULLEYS AND
REPLACE THE BELTS
7- THERE IS A MECHANICAL PROBLEM AT COMPRESSOR UNIT
IT COULD BE UNDERSTOOD BY NOISY OPERATION. INFORM THE SERVICE.
12-
THE OIL LOOSES ITS CHARACTERISTICS AND THE SEPARATOR GETS BLOCKED
RAPIDLY
1- THE RECOMMENDED OIL OR ORIGINAL SEPARATOR IS NOT BEING USED.
2- AMBIENT HUMIDITY IS TOO HIGH
3- THERE IS DUST, GAS ETC. IN THE ENVIRONMENT THAT IMPAIR THE PROPERTY OF OIL.
THIS POINT MUST IS TAKEN INTO CONSIDERATION WHEN DETERMINING THE COMPRESSOR
ROOM IN SANDBLASTING CASTING CHEMICAL AND PAINT / CHEMICAL FINISHING FACILITIES.
4- CONTINUOUSLY OPERATING IN HIGH AMBIENT TEMPERATURE
AT THE COMPRESSORS THAT OPERATE NEAR THE BOILER ROOMS, GENERATOR ROOM OR
AT AREAS WITH INSUFFICIENT VENTILATION, THE OPERATING TEMPERATURE ADVERSELY
AFFECTS THE LIFE OF SEPARATOR.
13-
THE CONTACTOR CONTACTS RAPIDLY WEAR OUT (RAPIDLY STICK):
1- THE VOLTAGE IS LOW
SEE ITEM 2.2
2- STAR PERIOD IS SHORT
IF THE STAR DELTA PERIOD IS ADJUSTED SHORTER THAN NORMAL, IT GETS LOADED UP
BEFORE FULL SPEED AND THE CONTACTOR CONTACTS ARE SUBJECTED TO EXCESSIVE
CURRENT. AS A RESULT OF THIS, THE CONTACTS MAY STICK AND YOUR MOTOR MAY BURN.
THE STAR DELTA PERIOD IS 4-6 SECONDS (ACCORDING TO COMPRESSOR TYPE). DO NOT
ADJUST IT FOR SHORTER PERIOD. REPLACE YOUR OLD CONTACTS WITH NEW ONES.
3- THE COMPRESSOR EXCESSIVELY STARTS AND STOPS
THE SUGGESTED MAXIMUM NUMBER OF START IN 1 HOUR IS 6. MORE RAPIDLY STARTING
AND STOPPING
CURRENT DRAW AT START UP THE OPERATIONAL COST INCREASES. FOR DETAILED
INFORMATION, CONTACT THE SERVICE.
4- ORIGINAL CONTACT SET IS NOT USED
THE ELECTRICAL RESISTANCES OF THE NON ORIGINAL CONTACT SETS ARE VERY LOW. FOR
PROVIDING ORIGINAL SPARE PARTS CONTACT SERVICE.
14-
THE BELTS ARE RAPIDLY WEAR OUT (ON BELT DRIVING COMPRESSORS)
1- THE PULLEY ADJUSTMENT IS DEFECTED
CHECK THE PULLEY ADJUSTMENT AND CORRECT IT. INFORM THE SERVICE
2- THE BELT TENSION IS TOO TIGHT / LOOSE.
CHECK THE BELT TENSION, INFORM THE SERVICE
3- CONTINUOUSLY OPERATING IN HIGH TEMPERATURE AN CORROSIVE ENVIRONMENT
INFORM THE SERVICE
AFFECTS ADVERSELY THE MECHANICAL LIFE AND DUE TO THE EXCESSIVE
