AUTOMATIC GREASE LUBRICATION GENERAL
INFORMATION
THE AUTOMATIC GREASE LUBRICATION SYSTEM IS
EMPLOYED AS A MEANS OF LUBRICATING THE SEAM-
ING ROLLS WHILE THE SEAMER IS RUNNING, AND
NOT HAVING TO SHUT DOWN THE SEAMER TO MANU
ALLY GREASE THE ROLLS. AT PREDETERMINED IN
TERVALS, THE SYSTEM WILL SUPPLY AN ADEQUATE
AMOUNT OF GREASE TO THE ROLLS AND ALSO RID
THE ROLLS OF OLD GREASE BY USING THE VACUUM
FEATURE.
AUTOMATIC GREASE LUBRICATION
OPERATION
GREASE CYCLE INTERVALS
THE GREASE CYCLE INTERVAL AT WHICH A GREASE
COMMAND IS GIVEN BY THE PLC, IS NORMALLY PRE
SET AT ONE (1) HOUR. NOTE: IF THE SEAMING ROLLS
HAVE THE CERAMIC BEARINGS INSTALLED, THE PRE
SET INTERVAL IS CHANGED TO SEVENTY TWO (72)
HOURS.
VACUUM SYSTEM OPERATION
WHEN A GREASE COMMAND IS INITIATED BY THE PLC PROGRAM THE CYCLE WILL START AS
LONG AS THE SEAMER IS IN OPERATION. THE VACUUM PUMP WILL TURN ON, BY THE VALVE
BEING ENERGIZED. THE TIME THE VACUUM PUMP IS ON IS PRESET IN THE PLC AND THIS WILL
BE
ENOUGH TIME TO SUCK OR PULL THE OLD GREASE FROM THE SEAMING ROLL. THE OLD
GREASE
WILL BE DEPOSITED IN THE RETURN GREASE JAR.
GREASE PUMP OPERATION
AT THE END OF THE VACUUM CYCLE, THE GREASE PUMP CYCLE WILL NOW START. THE
SOLENOID VALVE FOR THE PUMP WILL NOW ENERGIZE, AND THE PUMP WILL PROVIDE GREASE
INTO THE SYSTEM. THE PUMP WILL CONTINUE TO PUMP UNTIL THE SYSTEM PRESSURE SWITCH
IS ACTUATED. AT WHICH TIME THIS WILL RESET THE SYSTEM.
DIRECTIONAL VALVE OPERATION
THIS DIRECTIONAL VALVE HAS THREE (3) POSITIONS, THE CENTER POSITION BEING OPEN TO
SYSTEM VENT. ENERGIZING SOLENOID A WILL DIRECT THE GREASE TO THE SEAMER.
SOLENOID
"B" IS USED FOR DIRECTING THE GREASE TO THE FILLER CONNECTED TO THE 180S
SEAMER.
SYSTEM GREASE PRESSURE SWITCH OPERATION
THE GREASE SYSTEM CYCLE WILL BE COMPLETE IF THE SYSTEM PRESSURE SWITCH IS
ACTUATED. THE SWITCH IS ADJUSTABLE FROM 1500 TO 2500 PSI. ONCE THE SYSTEM
PRESSURE
IS MET, THIS WILL IN TURN DE-ENERGIZE THE GREASE PUMP SOLENOID AND
THE DIRECTIONAL
VALVE SOLENOID.
