Cov txheej txheem ua haujlwm ntawm txoj kev khiav dej num ntawm lub twj tso kua mis submersible

Ntau tus phooj ywg hais txog lub twj tso kua mis submersible muaj teeb meem, uas yog, dab tsi yog txoj kev khiav dej num, cov hauv qab no yog qhia rau koj txog cov txheej txheem ua haujlwm tshwj xeeb.

1. Qhov hluav taws xob throttling: Rau cov twj tso kua mis RPM qis thiab nruab nrab, qhov no yog ib txoj hauv kev pheej yig ntawm kev khiav dej num. Throttling tseem ceeb tuag taw tes yuav ua rau cov kua hauv lub twj tso kua mis overheat, tuaj yeem siv los tswj qhov tsim nyog ntws los ntawm kev hla, lossis nrog ntau txoj kev tswj hwm. Qhov no yog qhov tseem ceeb heev rau cov twj uas siv dej kub lossis cov kua dej tsis haum uas tau hais ua ntej.

2, suction inlet throttling: yog tias siv tau NPSH txaus, ces qee lub zog tuaj yeem txuag tau los ntawm kev throttling hauv cov kab nqus. Inlet throttling feem ntau yog siv nyob rau hauv dav hlau cav roj kab twj vim qhov hluav taws xob throttling yuav ua rau overheating los yog vaporization ntawm cov kua. Ntawm cov dej me me, lub impeller ntawm cov twj tso kua mis tsuas yog ib feem ntawm cov kua. Yog li ntawd, thaum lub hwj chim input thiab kub nce yog hais txog qhov hluav taws xob throttling, qhov ntws ntawm lub twj tso kua mis condensate ntawm 1/30 ntawm lub impeller lub peev xwm ua haujlwm tag nrho feem ntau yog tswj los ntawm submersive qhov tob 7, uas yog sib npaug rau inlet throttling. Cov qauv tsim tshwj xeeb tuaj yeem txo cov cavitation puas ntawm cov twj no mus rau qhov tsis tseem ceeb, tab sis lub zog theem kuj tseem qis dua.

3, bypass txoj cai: cov kab tawm ntawm lub raj xa dej tuaj yeem raug tshem tawm ntawm tag nrho lossis ib feem ntawm qhov ntws, los ntawm cov yeeb nkab hla mus rau lub twj tso kua mis los yog lwm cov ntsiab lus tsim nyog. Ib los yog ntau tshaj qhov ntws ntawm cov paib thiab cov tswj qhov tsim nyog tuaj yeem ntsia tau rau hauv cov bypass. Metering bypass feem ntau yog siv los txo qhov ntws ntawm lub boiler pub twj tso kua mis, feem ntau los tiv thaiv overheating. Kev txuag hluav taws xob ntau tuaj yeem ua tiav yog tias qhov ntau dhau ntawm cov twj bypass paddle twj tso kua mis hloov pauv rau lub qhov hluav taws xob throttling.

4, kev hloov ceev: siv txoj kev no los kho qhov ntws, tuaj yeem ua kom lub zog xav tau raug txo kom tsawg, thiab tuaj yeem tshem tawm cov dej ntws hauv cov txheej txheem ntawm overheating. Chav turbines thiab lub tshuab hluav taws xob sab hauv tuaj yeem hloov kho kom yooj yim rau kev tswj ceev ntawm tus nqi me me. Txhua yam ntawm txhua yam, sib nqus, hydraulic, thiab DC thiab AC hloov pauv ceev motors tuaj yeem siv los kho qhov ceev. Feem ntau, lub cev muaj zog sib txawv yog kim dhau thiab kho cov hniav yuav tsum tsuas yog siv thaum kev tshawb fawb nyiaj txiag ntawm cov xwm txheej tshwj xeeb ua pov thawj tsim nyog.

5. Huab cua rov ntxiv: Huab cua rov ntxiv rau qhov nqus dej ntawm lub raj xa dej kuj yog ib txoj hauv kev los tswj tus nqi ntws. Txoj kev no tuaj yeem txuag tau qee lub zog piv nrog lub qhov hluav taws xob throttling. Feem ntau, koj tsis xav kom huab cua hauv cov kua xa tawm, thiab ib txwm muaj kev pheej hmoo tias huab cua ntau dhau yuav ua rau lub twj tso kua mis poob nws lub taub hau, yog li txoj kev no tsis tshua siv hauv kev xyaum tshwj tsis yog muaj qee zaus.
