Z12B hom xauv sib dhos
1. Piv nrog rau kev cuam tshuam dav dav thiab kev sib txuas tseem ceeb, lub tes tsho sib txuas muaj ntau yam zoo:
(1) Kev siv lub tes tsho nthuav dav ua rau kev tsim khoom thiab kev teeb tsa ntawm lub tshuab tseem ceeb qhov chaw yooj yim. Lub machining ntawm lub ncej thiab lub qhov rau kev txhim kho lub tes tsho expansion tsis yuav tsum tau siab precision raug kam rau ua xws li cuam tshuam haum. Tsis tas yuav tsum muaj cua sov, cua txias lossis cov cuab yeej siv zog thaum lub tes tsho nthuav dav, tsuas yog yuav tsum tau ceev cov bolts raws li qhov xav tau torque. Thiab qhov kev hloov kho tau yooj yim, lub log hub tuaj yeem hloov kho kom yooj yim rau txoj haujlwm xav tau ntawm lub ncej. Lub tes tsho nthuav dav tuaj yeem siv los koom nrog cov khoom siv tsis zoo.
(2) Lub neej ua haujlwm ntev thiab lub zog siab ntawm lub tes tsho nthuav dav. Lub tes tsho nthuav dav cia siab rau kev sib txhuam sib kis, tsis muaj qhov tseem ceeb los ua kom tsis muaj zog ntawm qhov kev sib txuas, tsis muaj kev sib txheeb ze, thiab yuav tsis hnav hauv kev ua haujlwm.
(3) Thaum lub tes tsho nthuav dav yog overloaded, nws yuav poob qhov kev sib txuas muaj nuj nqi, uas tuaj yeem tiv thaiv cov cuab yeej los ntawm kev puas tsuaj.
(4) Lub tes tsho nthuav dav txuas tuaj yeem tiv taus ntau lub nra, thiab nws cov qauv tuaj yeem ua rau ntau hom. Raws li qhov loj ntawm lub installation load, ntau lub tes tsho nthuav dav tuaj yeem siv tau hauv cov koob.
(5) Lub tes tsho nthuav dav yog yooj yim rau disassemble thiab muaj kev sib hloov zoo. Txij li thaum lub tes tsho nthuav dav tuaj yeem muab cov ncej hub nrog qhov sib txawv loj dua, cov ntsia liaj qhov rooj tuaj yeem loosened thaum disassembled, yog li ntawd qhov txuas txuas tau yooj yim disassembled. Thaum qhov chaw sib cuag yog nruj, nws tsis yooj yim los tsim xeb, thiab nws kuj yog ib qho yooj yim rau kev sib txuas thiab disassemble.
2. Torque torque thiab axial torque ntawm lub tes tsho expansion
(1) Torque Mt yog hais txog qhov siab tshaj plaws theoretical torque thaum hloov lub zog ntshiab, thiab axial force Ft yog hais txog qhov siab tshaj plaws axial quab yuam uas tuaj yeem hloov pauv yam tsis hloov lub zog. Yog hais tias koj kis tsis tau tsuas yog torque tab sis kuj axial quab yuam.
(2) Tightening torque MA ntawm lub ntsia liaj qhov rooj
Lub torque Mt thiab axial quab yuam Ft teev nyob rau hauv tus txheej txheem yog xam raws li qhov sib thooj ntsia hlau nro, thiab zawm torque ntawm cov ntsia hlau yuav tsum ncav cuag qhov yuav tsum tau ntaus nqi nyob rau hauv lub technical parameter lub rooj.
