Equipment revision services

The primary goal of equipment revision is to avoid or mitigate the consequences of failure of equipment. This may be by preventing the failure before it actually occurs. Preventive maintenance can offer equipment a new lease on life by returning it to its original high-quality performance standards and productivity.

The care and servicing by personnel for the purpose of maintaining equipment in satisfactory operating condition by providing for systematic inspection, detection, and correction of incipient failures either before they occur or before they develop into major defects.

Preventive maintenance tends to follow planned guidelines to prevent equipment breakdown.  It consists in regular and routine actions taken on equipment including tests, measurements, adjustments, parts replacement, and cleaning, performed specifically in order to prevent its breakdown

It is designed to preserve and restore equipment reliability by replacing worn components before they actually fail. Maintenance activities include partial or complete overhauls at specified periods, parts changes, minor adjustments, regasketing, retightening, and so on. In addition, workers can record equipment deterioration so they know to replace or repair worn parts before they cause system failure. The ideal machine maintenance program would prevent any unnecessary and costly repairs.
