Sur­veys show that planning in­creases the pro­duc­tiv­ity of work per­for­mance by as much as 77 per­cent and as a re­sult makes planning and sched­ul­ing one of the most im­por­tant tasks for an or­gan­i­sa­tion. Op­er­at­ing hours or cal­en­dar based main­te­nance tim­ing is typ­i­cally used in in­dus­try, how­ever many com­pa­nies have be­gun us­ing con­di­tion-based main­te­nance (CBM) as an im­por­tant part of ex­tend­ing main­te­nance in­ter­vals and be­ing able to sched­ule main­te­nance work at the re­quired time.

Con­di­tion- based main­te­nance uses a range of pow­er­ful, non- in­va­sive mon­i­tor­ing tech­niques to de­ter­mine ma­chine con­di­tion and stores historical trend data to help pre­dict pos­si­ble fu­ture fail­ure of the ma­chine. This early warn­ing en­ables op­er­a­tors to im­prove their main­te­nance planning ac­tiv­i­ties, giv­ing more time to plan and to or­ga­nize the spare parts and re­sources needed to carry out cor­rec­tive mea­sures. In ad­di­tion, this early de­tec­tion gives the op­er­a­tor the op­por­tu­nity to carry out planned in­ter­ven­tions that help to avoid con­se­quen­tial dam­age to as­so­ci­ated ma­chine com­po­nents and sys­tems. The re­sult is ma­jor sav­ings in di­rect main­te­nance costs.

In­for­ma­tion col­lected through con­di­tion-based main­te­nance can also be used in de­ter­min­ing the root cause of prob­lems in order for these to be min­imised or elim­i­nated and can form the ba­sis of con­tin­u­ous im­prove­ment for both equip­ment avail­abil­ity and re­li­a­bil­ity dur­ing ser­vice.

SKF @ PTITUDE AS­SET MAN­AGE­MENT SYS­TEM

The hard­ware and soft­ware com­po­nents of the SKF @ ptitude As­set Man­age­ment Sys­tem have been de­signed to work to­gether with each other and with your fa­cil­ity’s CMMS in one in­te­grated plat­form. The sys­tem en­ables cus­tomers to in­te­grate all ma­chine con­di­tion data into one com­mon pro­gramme and share data seam­lessly across func­tional lines.

HARD­WARE

SKF vi­bra­tion mea­sure­ment tools put the ben­e­fits of con­di­tion- based main­te­nance within reach for ex­pert and novice users alike, with SKF of­fer­ing a wide va­ri­ety of con­di­tion mon­i­tor­ing hard­ware such as:

• Por­ta­ble i nstru­ments for col­lec­tion, stor­age and re­view of ma­chine con­di­tion and process data.

• In­spec­tion sys­tems and data man­agers for ac­cu­rately and con­sis­tently record­ing, trend­ing, stor­ing, com­mu­ni­cat­ing and act­ing on process and i nspec­tion data.

• On­line sys­tems for con­tin­u­ous ma­chine sur­veil­lance and pro­tec­tion.

• Vi­bra­tion sensors and eddy probe sys­tems for crit­i­cal ma­chine mon­i­tor­ing.

• Elec­tric mo­tor test­ing.

With min­i­mal i nvest­ment and train­ing, these tools can be used to start a new con­di­tion mon­i­tor­ing pro­gramme or com­ple­ment an ex­ist­ing one, eval­u­ate elec­tric mo­tor bear­ings, l ower en­ergy costs and re­duce CO2 emis­sions.
