Dab tsi yog qhov ua rau cov ntsia hlau puas ntawm lub tshuab txhaj tshuaj molding thiab yuav ua li cas?

1. Txhaj tshuaj molding tshuab txhaj cov ntsia hlau, qhov zoo tshaj plaws ntsia hlau chim, ntsia hlau puas yog vim li cas
① Qhov kub ntawm cov khoom raw plasticizing yog tsawg.
② Cov khoom siv raw yog tov nrog hlau impurities los yog muaj ntau impurities nyob rau hauv cov khoom raw.
③ Screw idling lub sij hawm ntev dhau lawm.
④ Kev xaiv cov khoom siv ntsia hlau tsis tsim nyog.
⑤ Cov ntsia hlau raug raug yog tsawg, thiab cov cua sov kho hardness ntawm cov ntsia hlau ua hauj lwm nto yog tsawg.
2. Txhaj tshuaj molding tshuab txhaj cov ntsia hlau, qhov zoo tshaj plaws ntsia hlau chim, ntsia hlau chaw tsim tshuaj paus disassembly ib ntus
Cov cuab yeej tshwj xeeb yuav tsum tau siv rau kev tshem tawm cov ntsia hlau, thiab cov rauj hnyav tsis raug tso cai. Cov txheej txheem tshem tawm tshwj xeeb yog raws li hauv qab no.
① Tshem lub nozzle thiab qhov txuas ntawm lub nozzle thiab lub thoob.
② Sib cais qhov tseem ceeb ntawm kev sib txuas ntawm cov ntsia hlau los ntawm lub tshuab tsav.
③ Tshem tawm cov flange txuas thiab txav cov ntsia hlau rau pem hauv ntej.
④ Thaum lub taub hau ntsia hlau raug rau lub thoob, tam sim ntawd tshem cov ntsia hlau taub hau txuas xov (ceeb toom: feem ntau ntawm cov xov ntawm no yog sab laug).
⑤ Tshem lub nplhaib thiab lub nplhaib sib khi ntawm lub hau.
⑥ Lub tshuab nqus tsev dismantled, kos lub nplhaib, lub nplhaib sib khi thiab cov ntsia hlau yuav tsum tau ntxuav nrog tooj liab txhuam thiab duav cov cuab yeej tam sim ntawd thaum nws kub. Cov khoom nplaum tshwj xeeb uas nyuaj rau kev ntxuav yuav tsum tau rhaub hauv qhov cub ntawm qhov kub qis tshaj plaws uas tuaj yeem ua rau cov khoom muag muag, thiab tom qab ntawd cov khoom seem yuav raug tshem tawm.
⑦ Sib sau tag nrho cov khoom ntawm cov ntsia hlau ua ke, thiab siv cov roj molybdenum disulfide tshav kub-resistant roj rau ntawm cov xov txuas txuas los pab txhawb kev sib cais tom ntej.
⑧ Cov ntsia hlau uas tsis siv rau lub sijhawm yuav tsum tau coated nrog cov roj tiv thaiv tom qab ntxuav, qhwv thiab dai rau hauv qhov chaw muaj cua thiab nyab xeeb.
3. Kev kho thiab hloov cov tshuaj txhaj tshuaj ntawm lub tshuab txhaj tshuaj molding
① Yog tias muaj me ntsis hnav lossis khawb ntawm qhov chaw ua haujlwm ntawm cov ntsia hlau, qhov chaw puas tuaj yeem ua rau hauv av thiab polished nrog oilstone los yog daim ntaub zoo abrasive.
② Thaum qhov chaw ua haujlwm ntawm cov ntsia hlau tau hnav hnyav thiab qhov caws pliav yog qhov sib sib zog nqus, xyuas thiab txheeb xyuas qhov ua rau ntawm cov ntsia hlau hnav thiab tshem tawm qhov txhaum kom tsis txhob muaj qhov tshwm sim zoo sib xws dua, thiab tom qab ntawd kho qhov sib sib zog nqus caws pliav los ntawm vuam. Yog hais tias cov xov ntawm tag nrho cov ntsia hlau yog hnyav heev, qhov haum clearance ntawm cov ntsia hlau thiab lub chim nce, qhov to ntawm cov khoom molten nce thiab qhov kev txhaj tshuaj kom muaj nuj nqis yog tsis ruaj tsis khov thaum lub sij hawm ua hauj lwm, cov xov txheej lub voj voog ntawm cov ntsia hlau yuav tsum thermally sprayed nrog hnav. -resistant alloy, thiab tom qab ntawd cov ntsia hlau yuav tsum tau grinded raws li qhov loj ntawm lub thoob sab hauv txoj kab uas hla thiab qhov haum clearance yuav tsum tau (saib Table 3-3).
Yog hais tias lub thoob yog hnav hnyav, txoj kab uas hla ntawm lub puab lub qhov nce tom qab kho, thiab kev sib tsoo ntawm cov ntsia hlau tom qab txau tsis tuaj yeem ua tau raws li qhov xav tau ntawm qhov sib txawv ntawm lub thoob thiab cov ntsia hlau, cov ntsia hlau yuav tsum rov ua dua. Sab nraud txoj kab uas hla ntawm cov ntsia hlau xov yuav tsum tau ua raws li qhov sib txuam clearance yuav tsum tau ntawm ob qhov chaw thiab qhov tseeb puab lub cheeb ntawm lub chim. 1. Cov ntsia hlau txhaj tshuaj ntawm lub tshuab txhaj tshuaj molding tshuab, qhov zoo tshaj plaws ntsia hlau chim, thiab ua rau cov ntsia hlau puas
① Qhov kub ntawm cov khoom raw plasticizing yog tsawg.
② Cov khoom siv raw yog tov nrog hlau impurities los yog muaj ntau impurities nyob rau hauv cov khoom raw.
③ Screw idling lub sij hawm ntev dhau lawm.
