maintenance
As maintenance according to DIN 31051 (2003) measures to delay the degradation of the existing wear reserve understand the viewing unit. It is applied while an object is in use . Maintenance is carried out in accordance with technical rules or a manufacturer's specification (for example, after a certain mileage or duration, the maintenance interval ). In this way, the scope of maintenance (and thus its operating costs ) is already determined as part of the purchase decision . A distinction must be made between maintenance . Maintenance - like repairs and inspections - is part of maintenance. The type and scope of this can be designed by the operator / maintenance engineer according to his specifications.
Maintenance is generally carried out at regular intervals and often by trained specialists. This ensures the longest possible service life and low wear and tear on the objects being serviced. Professional maintenance is often a prerequisite for granting the warranty .
Maintenance of technical objects
After a possibly necessary backup of the maintenance personnel by maintenance safeguards, maintenance includes e.g. For example, readjusting, lubricating, preserving, refilling, adding or replacing operating materials or consumables (e.g. fuel, lubricant or water) and the scheduled replacement of wearing parts (e.g. filters or seals) if their expected service life is obvious or is shorter than the next maintenance interval as specified by the manufacturer. Cleaning is also part of maintenance. Cleaning includes the removal of foreign and auxiliary substances (by vacuuming, scrubbing, using solvents, etc.). The sub-measures of maintenance lead to a slowdown in the degradation of the wear reserve from the time of maintenance.
The replacement of defective parts is part of the repair . Smaller defects are often corrected in the course of regular maintenance work (so-called minor repairs). The demarcation to maintenance and the measures to be carried out as well as the deadlines to be observed are specified in the instructions for use .
Maintenance planning
Maintenance planning software is often used to schedule maintenance. The technical data of the system to be maintained are recorded in the solution. The system then generates automatic reminders when the technical object has to be serviced again. Comprehensive solutions also include a ticket system and planning boards to keep track of all operations. Maintenance planning can also be part of ERP solutions or service management software.
