Pwm Cartridge rhaub kom kub kub? Txoj kev teeb tsa yuav yog qhov teeb meem

Ntau tus kws tshaj lij tsim khoom tau muaj qhov teeb meem ntxhov siab no: lub tshuab hluav taws xob tshiab tso tseg tsis ua haujlwm tom qab siv sijhawm luv luv, cov pwm tuaj yeem kub tsis txaus, thiab cov khoom zoo pib poob qis. Qhov teeb meem lub hauv paus tseem tsis tau paub dua tom qab kuaj xyuas cov khoom siv hluav taws xob thiab xyuas kom cov xaim yog OK.

Raws li ntau qhov kev paub dhau los, cov teeb meem no feem ntau tshwm sim los ntawm qhov lawv tau teeb tsa li cas. Tib neeg siv txoj cai- lub kaum sab xis txhuas lub tshuab tso cua sov ntau rau cov pwm pwm, xws li txhaj tshuaj pwm thiab tuag- casting pwm. Cov hlau lead uas tawm ntawm lub tshuab cua sov no yog khoov ntawm 90-degree lub kaum sab xis ntawm lub tshuab rhaub lub cev. Qhov kev tsim no zoo meej rau qhov chaw uas tsis muaj ntau chav thiab cov hlau lead yuav tsum khiav ntawm cov pwm nto.


Nyob rau hauv qhov tseeb, lub rhaub thiab nws bore yuav tsum haum ua ke zoo kawg nkaus rau pwm cua sov ua hauj lwm. Yog hais tias qhov kev ncua deb ntawm lub rhaub lub sab nraud txoj kab uas hla thiab cov pwm bore yog ntau tshaj 0.05 millimeters, qhov ua tau zoo ntawm tshav kub hloov mus rau ntau heev. Lub rhaub yog tam sim no "tso tseg" nyob rau hauv lub bore. Qhov kub thiab txias sab hauv tuaj yeem nce sai vim tias lub rhaub dej tsis tuaj yeem tshem tawm ntawm nws cov cua sov, uas ua rau kom muaj kev laus ntawm magnesium oxide rwb thaiv tsev thiab txiav lub rhaub lub neej luv luv los ntawm ntau. Qee cov kws tshaj lij txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhim kho yooj yim dua, tab sis qhov no feem ntau tsis ua haujlwm.


Lwm qhov tseem ceeb uas yuav tau xav txog thaum xaiv yog qhov chaw thau khoom. Rau cov pwm cua sov li qub, nws yog qhov zoo tshaj kom khaws cov khoom ntim ntawm 5 thiab 10 watts ib square centimeter. Higher power densities let the heater heat up faster, but they put a lot of stress on the sheath material and interior structure. Yog tias koj xav tau ib yam dab tsi los ua haujlwm rau lub sijhawm ntev yam tsis muaj teeb meem, zoo li lub tshuab ua haujlwm kub, koj yuav tsum xaiv tus qauv nrog lub teeb tsa- hauv thermocouple kom koj tuaj yeem saib xyuas qhov kub ntawm lub sijhawm.

Kev siv cov thermal muab tshuaj txhuam rau hauv lub tshuab rhaub dej thaum lub sij hawm teeb tsa pab sau cov qhov khoob me me, uas ua rau cov cua sov hloov tau zoo dua. Tsis txhob rub cov hlau lead thaum koj tshem tawm lub rhaub. Hloov chaw, siv tus pas tooj tooj kom ua tib zoo coj mus rhaub nws tawm ntawm sab nraub qaum kom tsis txhob muaj cov xaim sab hauv los ntawm kev puas tsuaj. Cov ntaub ntawv pwm sib txawv, suav nrog P20 steel thiab H13 steel, nthuav thiab cog lus ntawm cov nqi sib txawv thaum lawv kub. Lub clearance tso cai yuav tsum tau hloov kom haum qhov no.

Thaum kawg, cua sov pwm yog ib qho teeb meem uas cov engineers yuav tsum tau daws ntawm qhov system theem. Txhua yam me me tseem ceeb, los ntawm kev xaiv lub tshuab cua sov kom zoo rau kev siv lub tshuab kom raug rau kev txhim kho kom raug. Cov cuab yeej siv tau tsuas yog ua haujlwm ntseeg tau yog tias tag nrho nws cov khoom raug muab tso ua ke kom tsim nyog. Rau ntau qhov nyuaj- kab noj hniav pwm lossis tuag loj- cov pwm pwm, nws yog qhov zoo tshaj plaws los tham nrog cov chaw tsim khoom tshwj xeeb txog kev tsim cov cua sov tag nrho los tiv thaiv kev ua yuam kev kim.
