⑴ Cov khoom xau ntawm qhov sib txuas ntawm pwm thiab lub thoob:
Cov laj thawj yog:
① Kev ua tiav qhov tseeb ntawm kev sib txuas thiab mating ntawm ob qhov chaw yog tsawg. ⒈ Cov mating nto yog ntxhib; ⒉ Qhov tseeb qhov tseeb ntawm qhov chaw mating thiab cov kab nruab nrab ntawm lub cev pwm yog tsawg. ② Ob qhov chaw sib txuas ntawm kev sib txuas tsis huv thiab muaj cov khoom txawv teb chaws.
Txoj kev daws teeb meem muaj xws li:
① Rov ua kom haum cov pwm lub cev qhov sib koom ua ke, ⒈ Txhim kho qhov smoothness ntawm mating nto; ⒉ Xyuas kom meej qhov perpendicularity ntawm mating nto thiab kab nruab nrab ntawm lub pwm lub cev. ② Tshawb xyuas thiab tshem tawm cov av thiab cov khoom txawv teb chaws ntawm ob qhov chaw sib cuag.
⑵ Tsis yooj yim rau disassembly:
Cov laj thawj yog:
① Muaj ntau dhau ntawm cov khoom sib dhos hauv lub cev pwm. ② Yuav tsum tsis muaj burrs ntawm tag nrho cov mating qhov chaw ua ntej sib dhos. ③ Cov khoom sib txuas bolts tsis coated nrog silicone roj ua ntej sib dhos. ④ Deformation ntawm qhov chaw.
Txoj kev daws teeb meem muaj xws li:
①Remanufacture los txhim kho qhov tseeb ntawm qhov sib txuam. ② Ntxuav cov khoom ua ntej sib dhos. ③ Siv cov roj silicone roj uas kub kub ua ntej sib sau ua ke. ④ Hloov cov khoom yuav tsum tau ua los ntawm kub resistant thiab me me deformation hlau.
⑶ Cov ntsia hlau txuas yog yooj yim tawg:
Cov laj thawj yog:
① Kev siv tsis raug. ② Kev xaiv cov khoom tsim khoom tsis tsim nyog.
Txoj kev daws teeb meem muaj xws li:
① Thaum kho cov ntsia hlau tuag qhov sib txawv, ua ntej loosen cov ntsia hlau ntawm qhov me me ntawm qhov sib txawv ntawm qhov tuag, thiab tom qab ntawd kho thiab zawm cov ntsia hlau rau ntawm qhov loj ntawm qhov tuag qhov sib txawv. ② Yog tias tsim nyog, nws yuav tsum tau ua los ntawm 45 steel thiab kho cua sov kom lub hardness ntawm 40 ~ 45HRC.
⑷ Deformation ntawm qhov chaw hauv pwm:
Cov laj thawj yog:
① Txoj kev disassembly tsis raug. ②Squeezed los ntawm cov khoom hnyav thaum khaws cia. ③ Kev xaiv cov khoom tsim khoom tsis tsim nyog.
Txoj kev daws teeb meem muaj xws li:
① Tsis txhob ntaus nrog rauj hnyav thaum lub sij hawm disassembly thiab installation. ② Tsis muaj cov khoom hnyav raug tso cai rau muab tso rau hauv pwm lub cev thaum khaws cia. ③ Ua los ntawm kub resistant, me me deformation steel.
⑸ Cov khoom lag luam tsis ruaj khov thiab kev hloov kho yog qhov nyuaj:
Cov laj thawj muaj xws li: kev tsim khoom tsawg tsawg ntawm cov khoom hauv pwm, kev xaiv tsis raug ntawm kev sib koom ua ke raug, thiab cov khoom sib xyaw ntxhib.
Txoj kev daws teeb meem muaj xws li:
Cov pwm yog remanufactured, thiab qhov haum ntawm qhov chaw yuav tsum yog H7 / h6; Qhov saum npoo roughness Ra ntawm mating nto yuav tsum tsis txhob ntau tshaj 1.25um; qhov nto roughness Ra ntawm lub yaj ntws channel yuav tsum tsis txhob ntau tshaj 0.25um; xyuas kom meej qhov tseeb ntawm qhov mating nto thiab qhov nruab nrab ntawm qhov.
⑹ Tus nqi ntws ntawm cov khoom extruded los ntawm kev tuag tsis ruaj khov:
Cov laj thawj yog:
① Qhov kub ntawm ntau qhov ntawm lub cev pwm yog qhov tsis sib xws thiab qhov yuam kev loj. ② Qhov sib txawv ntawm qhov tuag thiab lub mandrel tsis sib xws. ③ Muaj cov khoom txawv teb chaws thaiv cov pwm. ④Plasticizing system teeb meem (txhim kho cov khoom siv raw hauv lub hopper; tsis ruaj khov plasticizing kub, qhov kub thiab txias hloov pauv ntau, qhov sib txawv ntawm cov ntsia hlau thiab lub thoob; tsis ruaj khov ceev ceev, thiab lwm yam).
Txoj kev daws teeb meem muaj xws li:
① Tshawb xyuas lub rhaub thiab hloov cov khoom puas; xyuas kom lub tsho cua sov nyob rau hauv kev sib cuag zoo nrog pwm. ② Kho qhov sib txawv ntawm qhov tuag thiab lub mandrel. ③ Disassemble lub pwm thiab tshem tawm cov khoom txawv teb chaws. ④ Tshawb xyuas cov txheej txheem plasticizing thiab daws teeb meem.
