Maintenance thiab txij nkawm cov ntsiab lus:
1. Kev tshuaj xyuas txhua hnub: Ua qhov kev tshuaj xyuas qhov muag ntawm cov qhov muag thiab cov hooks tsis tu ncua txhawm rau saib pom cov kab nrib pleb, deformation, hnav lossis corrosion.
2. Kev Tu: So tus nuv kom huv si ua ntej thiab tom qab siv kom tshem tawm cov plua plav, roj thiab cov khib nyiab los tiv thaiv corrosion thiab hnav.
3. Lubrication: Lubricate rotating qhov chaw ntawm tus nuv thiab cov khoom uas muaj roj txiv mis tsis tu ncua kom txo tau hnav thiab ua kom zoo ua haujlwm.
4. Kev tshuaj xyuas lub fastener: xyuas tag nrho cov bolts, screws thiab cotter pins kom paub meej tias lawv ua tiav thiab txhim kho kom zoo yam tsis muaj qhov xoob lossis puas.
5. Kev soj ntsuam kev hnav: Tshawb xyuas cov hlua khi thiab lub log rau kev hnav tsis tu ncua, paub meej tias txoj hlua hlau sib tw rau lub log, thiab lub rubey tsis xoob lossis tshee.
6. Kev ywj pheej ntawm kev sib hloov: xyuas kom meej tias qhov kev sib hloov ntawm qhov sib txuas ntawm qhov sib txuas yog qhov sib txawv thiab qhov sib txawv tsis tuaj yeem loj dhau. Yog tias nws nyuaj rau tig los yog xav tias daig, xyuas seb cov bearings thiab lub tes tsho puas puas lossis tsis txaus lubricated.
7. Kev tshuaj xyuas kev puas tsuaj ntau dhau: Tshawb xyuas seb lub ntsiab sib txuas puas muaj cov cim ntawm kev puas tsuaj, seb lub phaj sab yog elongated, seb lub qhov taub yog elongated, seb lub ntsia liaj qhov rooj yog khoov lossis elongated, tawg, thiab lwm yam.
8. Anti-unhooking ntaus ntawv: Xyuas seb lub anti-unhooking ntaus ntawv puas zoo lawm thiab xyuas kom meej nws ib txwm ua hauj lwm.
9. Kev tshuaj xyuas cov kws tshaj lij tsis tu ncua: Ua cov kws tshaj lij kev tshuaj xyuas tsawg kawg ib xyoos ib zaug, siv txoj hauv kev xws li kev kuaj pom cov xim tsis zoo, kuaj pom cov khoom sib nqus, kuaj xyuas qhov tsis zoo ultrasonic lossis X-ray flaw nrhiav kom pom kev puas tsuaj sab hauv.
10. Cov txheej txheem khib nyiab: Yog tias tus nuv muaj cov xwm txheej hauv qab no, nws yuav tsum tau muab pov tseg: qhov qhib loj dua li qhov qub, cov kab nrib pleb, qhov txaus ntshai ntu hnav mus txog 10% ntawm qhov loj me, torsional deformation tshaj 10 degree, phaj nuv bushing los yog mandrel hnav mus txog 5% ntawm qhov loj me, vuam kho lossis cuam tshuam los ntawm qhov kub thiab txias, muaj zog corrosion, thiab lwm yam.
Ua raws li cov ntsiab lus tu xyuas no yuav pab tiv thaiv kev sib tsoo thiab ua kom muaj kev nyab xeeb ntawm kev ua haujlwm.
