3. JB/T6439-92

4.3.3 Thaum split case twj tso kua mis Nws yog khiav raws li cov kev cai ua hauj lwm, qhov kub ntawm sab nrauv ntawm lub built-in bearing yuav tsum tsis txhob siab tshaj qhov kub ntawm lub conveying nruab nrab ntawm 20 ° C, thiab qhov siab tshaj plaws kub yuav tsum tsis txhob siab tshaj 80 ° C. Qhov kub nce ntawm qhov chaw sab nrauv ntawm sab nrauv mounted bearing yuav tsum tsis txhob siab tshaj qhov kub ntawm 40 ° C. Qhov kub siab tshaj plaws yog tsis siab tshaj 80 ° C.

4. JB/T7255-94

5.15.3 Qhov kev pabcuam kub ntawm cov kabmob. Qhov kub nce ntawm cov kabmob yuav tsum tsis pub tshaj qhov ntsuas kub ntawm 35 ° C, thiab qhov siab tshaj plaws yuav tsum tsis pub tshaj 75 ° C.

5. JB/T7743-95

7.16.4 Qhov kub nce ntawm cov kabmob yuav tsum tsis txhob siab tshaj qhov ntsuas kub ntawm 40 ° C, thiab qhov siab tshaj plaws yuav tsum tsis pub tshaj 80 ° C.

6. JB/T8644-1997

4.14 Qhov kub nce ntawm cov kabmob yuav tsum tsis pub tshaj qhov ntsuas kub ntawm 35 ° C, thiab qhov siab tshaj plaws yuav tsum tsis pub tshaj 80 ° C.

Lub cev muaj zog Bearing Temperature Regulations & Abnormal Causes & Treatment

Cov kev cai teev tseg tias qhov siab tshaj plaws ntawm cov kabmob dov tsis tshaj 95 ° C, thiab qhov siab tshaj plaws ntawm cov kabmob zawv zawg tsis tshaj 80 ° C. Thiab qhov kub nce siab tsis tshaj 55 ° C (qhov kub nce yog qhov ntsuas kub ntawm qhov ntsuas kub ntawm qhov ntsuas kub thaum lub sijhawm ntsuas).

1. Yog vim li cas: Cov ncej yog khoov thiab tsis pub txoj kab nruab nrab. Txheej txheem; rov nruab nrab.

2. Yog vim li cas: Lub hauv paus screws yog xoob. Kev kho mob: Tighten lub hauv paus screws.

3. Yog vim li cas: Cov roj lubricating tsis huv. Kev kho mob: hloov cov roj lubricating.

4. Yog vim li cas: Cov roj lubricating tau siv ntev dhau lawm thiab tsis tau hloov. Kev Kho Mob: Ntxuav cov bearings thiab hloov cov roj lubricating.

5.Yog vim li cas: Lub pob lossis cov menyuam hauv cov kabmob puas lawm.

Kev kho mob: hloov cov kabmob tshiab. Raws li lub teb chaws tus qauv, F-chav rwb thaiv tsev thiab B-chav soj ntsuam, qhov kub thiab txias ntawm lub cev muaj zog yog tswj ntawm 80K (txoj kev tiv thaiv), 90K (cov qauv txheej txheem). Xav txog qhov ntsuas kub ntawm 40 ° C, qhov siab tshaj plaws ua haujlwm ntawm lub cev muaj zog tsis tuaj yeem tshaj 120/130 ° C. Qhov siab tshaj plaws bearing kub yog 95 ° C. Siv rab phom infrared los ntsuas qhov kub ntawm sab nrauv ntawm cov kabmob. Raws li kev paub dhau los, qhov kub siab tshaj plaws ntawm 4-ncej lub cev muaj zog yuav tsum tsis pub tshaj 70 ° C. Rau lub cev muaj zog, tsis tas yuav tsum tau saib xyuas. Tom qab lub cev muaj zog tsim, nyob rau hauv ib txwm muaj xwm txheej, nws qhov kub thiab txias yog qhov qub, thiab yuav tsis hloov lossis nce ntxiv nrog kev ua haujlwm ntawm lub cev muaj zog. Bearings yog qhov tsis yooj yim thiab yuav tsum tau sim.
