Extruder chim

Nws feem ntau yog ib lub thoob hlau ua los ntawm cov hlau alloy lossis cov yeeb nkab sib xyaw nrog cov hlau hlau hauv ob sab phlu. Nws cov yam ntxwv tseem ceeb yog kub kub thiab siab tsis kam, muaj zog hnav tsis kam thiab corrosion kuj. Feem ntau, qhov ntev ntawm lub thoob yog 15 mus rau 30 npaug ntawm nws txoj kab uas hla, thiab nws qhov ntev yog raws li lub hauv paus ntsiab lus uas cov khoom tuaj yeem ua kom sov thiab cov yas sib npaug. Lub thoob yuav tsum muaj txaus thickness thiab rigidity. Sab hauv yuav tsum du, tab sis qee lub thoob tau kos nrog ntau yam grooves kom muaj kev sib txhuam nrog cov yas. Sab nraud ntawm lub thoob yog nruab nrog hluav taws xob cua sov, kub tsis siv neeg tswj cov cuab yeej thiab cov tshuab cua txias rau cua sov los ntawm kev tiv thaiv, inductance thiab lwm txoj kev.
1. Muaj peb hom qauv ntawm cov thoob:
(1) Integral chim
Txheej txheem - ua tiav ntawm tag nrho cov khoom.
Qhov zoo - yooj yim los xyuas kom meej kev tsim khoom siab thiab kev sib dhos raug, tuaj yeem ua kom yooj yim rau kev sib dhos ua haujlwm, lub thoob yog rhuab sib npaug, thiab muaj ntau daim ntawv thov.
Qhov tsis zoo - vim qhov ntev ntawm lub thoob, cov txheej txheem ua tiav yog siab, thiab cov kev cai rau kev ua cov cuab yeej tseem nruj heev. Sab hauv ntawm lub thoob yog qhov nyuaj los kho tom qab hnav.
(2) Cov khoom sib xyaw ua ke
Txoj kev ua: Faib lub thoob rau ob peb ntu, thiab tom qab ntawd txuas txhua ntu nrog flanges lossis lwm yam ntaub ntawv.
Qhov zoo: Kev ua haujlwm yooj yim, yooj yim los hloov qhov sib piv, feem ntau yog siv rau hauv cov xwm txheej uas qhov sib piv ntawm cov ntsia hlau yuav tsum tau hloov.
Disadvantages: High processing raug yuav tsum tau. Vim muaj coob tus ntawm cov seem, nws yog ib qhov nyuaj los xyuas kom meej lub coaxiality ntawm txhua seem. Qhov kev sib txuas ntawm flange rhuav tshem qhov sib xws ntawm lub thoob cua sov, ua kom sov poob, thiab nyuaj rau kev teeb tsa thiab tswj cov cua sov thiab cua txias.
(3) Bimetallic chim
Txoj kev ua: Inlay lossis nrum txheej ntawm cov khoom siv hlau hlau hauv cov pa roj carbon dav hlau lossis cam khwb cia hlau matrix. Nws tuaj yeem tsis tsuas yog ua tau raws li lub thoob cov khoom siv, tab sis kuj txuag cov khoom siv hlau zoo nkauj.
① Bushing chim: Lub thoob yog nruab nrog ib tug hloov tau alloy steel bushing. Nws txuag cov khoom muaj txiaj ntsig zoo, lub bushing yog hloov tau, thiab kev pabcuam lub neej ntawm lub thoob yog nce. Txawm li cas los xij, nws cov qauv tsim, kev tsim khoom thiab kev sib dhos yog qhov nyuaj.
② Casting chim: Ib txheej ntawm alloy txog 2 hli tuab yog centrifugally cam khwb cia rau sab hauv phab ntsa ntawm lub thoob, thiab ces qhov yuav tsum tau lub thoob sab hauv txoj kab uas hla loj yog tau los ntawm kev sib tsoo. Cov txheej txheej hlau yog zoo sib koom ua ke rau hauv lub thoob khib nyiab thiab sib npaug sib npaug raws li qhov ntev axial ntawm lub thoob. Nws tsis muaj qhov xav tau tev tawm lossis tawg, thiab muaj cov khoom zawv zawg, hnav tsis kam, thiab ua haujlwm ntev.
(4) IKV ib
1. Longitudinal grooves yog muab rau ntawm phab ntsa sab hauv ntawm lub thoob ntim khoom noj
Txhawm rau txhim kho tus nqi thauj khoom, cov kev xav tau ntawm cov khoom xa tawm qhia tau hais tias ib txoj hauv kev yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm mus rau qhov ntsia hlau axis. Cov grooves ntev yog muab rau ntawm phab ntsa sab hauv ntawm lub thoob ntim khoom noj thiab cov phab ntsa sab hauv ntawm lub thoob nyob ze ntawm qhov chaw noj mov yog ua rau lub khob hliav qab, uas yog cov kev siv ntawm ob txoj kev no.
2. Kev quab yuam txias ntawm cov khoom noj khoom haus
Txhawm rau ua kom cov khoom muaj peev xwm, muaj lwm txoj hauv kev. Nws yog ua kom txias qhov chaw pub mis, lub hom phiaj yog ua kom qhov kub thiab txias ntawm cov khoom xa tawm hauv qab qhov muag muag los yog melting point, tsis txhob pom cov yeeb yaj kiab yaj, thiab tswj cov khoom sib txhuam ntawm cov khoom.
Tom qab siv cov txheej txheem saum toj no, qhov kev xa tawm tau nce los ntawm {{0}}.3 mus rau 0.6, thiab cov ntim extrusion tsis tshua muaj siab rau kev hloov pauv ntawm lub taub hau tuag.
