MAINTENANCE & ITS TYPES


MAINTENANCE AND ITS TYPES

MAINTENANCE:-
MAINTENANCE INVOLVES KEEPING THE WORKPLACE, ITS STRUCTURES, EQUIPMENT, MACHINES, FURNITURE AND FACILITIES IN GOOD REPAIR AND OPERATING EFFICIENTLY AND SAFELY

BREAKDOWN MAINTENANCE
IT MEANS THAT PEOPLE WAITS UNTIL EQUIPMENT FAILS AND REPAIR IT. SUCH A THING COULD BE USED WHEN THE EQUIPMENT FAILURE DOES NOT SIGNIFICANTLY AFFECT THE OPERATION OR PRODUCTION OR GENERATE ANY SIGNIFICANT LOSS OTHER THAN REPAIR COST.

PREVENTIVE MAINTENANCE
IT IS A DAILY MAINTENANCE (CLEANING, INSPECTION, OILING AND RE-TIGHTENING), DESIGN TO RETAIN THE HEALTHY CONDITION OF EQUIPMENT AND PREVENT FAILURE THROUGH THE PREVENTION OF DETERIORATION, PERIODIC INSPECTION OR EQUIPMENT CONDITION DIAGNOSIS, TO MEASURE DETERIORATION. IT IS FURTHER DIVIDED INTO PERIODIC MAINTENANCE AND PREDICTIVE MAINTENANCE. JUST LIKE HUMAN LIFE IS EXTENDED BY PREVENTIVE MEDICINE, THE EQUIPMENT SERVICE LIFE CAN BE PROLONGED BY DOING PREVENTIVE MAINTENANCE.
  •  PERIODIC MAINTENANCE (TIME BASED MAINTENANCE - TBM)

TIME BASED MAINTENANCE CONSISTS OF PERIODICALLY INSPECTING, SERVICING AND CLEANING EQUIPMENT AND REPLACING PARTS TO PREVENT SUDDEN FAILURE AND PROCESS PROBLEMS. 
  •  PREDICTIVE MAINTENANCE

THIS IS A METHOD IN WHICH THE SERVICE LIFE OF IMPORTANT PART IS PREDICTED BASED ON INSPECTION OR DIAGNOSIS, IN ORDER TO USE THE PARTS TO THE LIMIT OF THEIR SERVICE LIFE. COMPARED TO PERIODIC MAINTENANCE, PREDICTIVE MAINTENANCE IS CONDITION BASED MAINTENANCE. IT MANAGES TREND VALUES, BY MEASURING AND ANALYZING DATA ABOUT DETERIORATION AND EMPLOYS A SURVEILLANCE SYSTEM, DESIGNED TO MONITOR CONDITIONS THROUGH AN ON-LINE SYSTEM.

CORRECTIVE MAINTENANCE
IT IMPROVES EQUIPMENT AND ITS COMPONENTS SO THAT PREVENTIVE MAINTENANCE CAN BE CARRIED OUT RELIABLY. EQUIPMENT WITH DESIGN WEAKNESS MUST BE REDESIGNED TO IMPROVE RELIABILITY OR IMPROVING MAINTAINABILITY.

MAINTENANCE PREVENTION
IT INDICATES THE DESIGN OF A NEW EQUIPMENT. WEAKNESS OF CURRENT MACHINES ARE SUFFICIENTLY STUDIED (ON SITE INFORMATION LEADING TO FAILURE PREVENTION, EASIER MAINTENANCE AND PREVENTS OF DEFECTS, SAFETY AND EASE OF MANUFACTURING) AND ARE INCORPORATED BEFORE COMMISSIONING A NEW EQUIPMENT.

MANUFACTURING PROCESS - DRAFT OR TAPER ALLOWANCE

DRAFT OR TAPER ALLOWANCE BY DRAFT IS MEANT THE TAPER PROVIDED BY THE PATTERN MAKER ON ALL VERTICAL SURFACES OF THE PATTERN SO THAT IT CAN BE REMOVED FROM THE SAND WITHOUT TEARING AWAY THE SIDES OF THE SAND MOLD AND WITHOUT EXCESSIVE RAPPING BY THE MOLDER. FIGURE  SHOWS A PATTERN HAVING NO DRAFT ALLOWANCE BEING REMOVED FROM THE PATTERN. IN THIS CASE, TILL THE PATTERN IS COMPLETELY LIFTED OUT, ITS SIDES WILL REMAIN IN CONTACT WITH THE WALLS OF THE MOLD, THUS TENDING TO BREAK IT.  FIGURE  IS AN ILLUSTRATION OF A PATTERN HAVING PROPER DRAFT ALLOWANCE. HERE, THE MOMENT THE PATTERN LIFTING COMMENCES, ALL OF ITS SURFACES ARE WELL AWAY FROM THE SAND SURFACE. THUS THE PATTERN CAN BE REMOVED WITHOUT DAMAGING THE MOLD CAVITY.  PATTERN HAVING DRAFT ON VERTICAL EDGES DRAFT ALLOWANCE VARIES WITH THE COMPLEXITY OF THE SAND JOB. BUT IN GENERAL INNER DETAILS OF THE PATTERN REQUIRE HIGHER DRAFT THAN OUTER SURFACES. THE AMOUNT OF DRAFT DEPENDS UPON THE LENGTH OF THE...

Boiler Mounting - Water Level Indicator

WATER LEVEL INDICATOR Function:   It is indicates the water level inside the boiler to an observer. Working:  The water of the boiler comes into the glass tube through the lower tube and the steam through the upper tube. The water then stands in the glass tube at the same level as in the boiler. Two cocks are used to control the passage of between the boiler and the glass tube while the third cock is in used to discharge some of the water from inside the boiler to see whether the gauge is in proper order or not. The glass tube is protected by means of a cover, made of specially toughened glass, which will prevent any accident that may happen due to breaking of glass tube. It is used for ordinary boilers.
