Ntau tus phooj ywg muaj lus nug txog lub twj tso kua mis submersible, uas yog, dab tsi yog txoj kev khiav dej num. Cov hauv qab no yuav qhia koj txog kev ua haujlwm tshwj xeeb.
1. Qhov hluav taws xob throttling: Rau cov twj tso kua mis qis thiab nruab nrab, qhov no yog ib qho kev hloov pauv uas pheej yig thiab pheej yig. Throttling mus rau qhov tuag taw tes yuav ua rau overheating ntawm cov kua nyob rau hauv lub twj tso kua mis, ib tug bypass yuav siv tau los tswj qhov tsim nyog txaus, los yog ib tug txawv txoj kev yuav siv tau. Qhov no yog qhov tseem ceeb heev rau cov twj uas tau hais los saum toj no tuav cov dej kub lossis cov kua dej tsis haum.
2. Suction port throttling: Yog tias muaj NPSH txaus, ces qee lub zog tuaj yeem txuag tau los ntawm throttling hauv cov kab nqus. Dav hlau cav roj kab twj feem ntau siv throttling nyob rau hauv vim throttling yuav ua rau overheating los yog vaporization ntawm cov kua. Ntawm tus nqi qis heev, lub impeller ntawm cov twj tso kua mis tsuas yog ib feem ntawm cov kua, yog li lub zog nkag thiab qhov kub thiab txias yog li 1/30 ntawm tag nrho cov impeller txoj hauj lwm ntawm qhov hluav taws xob throttling. Qhov no sib npaug rau throttling. Cov qauv tsim tshwj xeeb txo cov cavitation kev puas tsuaj ntawm cov twj tso kua mis mus rau theem tsis tseem ceeb, tab sis cov qib zog kuj tseem qis dua.
3. Kev hloov kho bypass: Tag nrho lossis ib feem ntawm cov dej ntws tuaj yeem hloov tau los ntawm kev tso tawm ntawm lub raj xa dej, thiab coj mus rau qhov chaw nqus ntawm lub twj tso kua mis lossis lwm cov ntsiab lus tsim nyog los ntawm cov yeeb nkab bypass. Ib los yog ntau tshaj ntws orifices thiab tsim nyog tswj li qub tuaj yeem ntsia tau rau hauv lub bypass. Metering bypass feem ntau yog siv los txo cov boiler pub twj tso kua mis ntws, feem ntau los tiv thaiv overheating. Kev txuag hluav taws xob ntau tuaj yeem ua tiav yog tias qhov ntau dhau ntawm lub tshuab bypass kiv cua siv los hloov lub qhov hluav taws xob throttling.
4. Kev hloov kho ceev: Thaum siv txoj kev no los kho qhov ntws, qhov xav tau lub zog yuav raug txo kom tsawg, thiab qhov tshwm sim overheating thaum lub sij hawm hloov cov txheej txheem yuav raug tshem tawm. Chav turbines thiab combustion engines yog yooj yim yoog raws li kev ceev ceev nrog me ntsis nqi ntxiv. Ntau yam khoom siv hluav taws xob, sib nqus, thiab hydraulic hloov pauv ceev, nrog rau DC thiab AC hloov pauv ceev motors, tuaj yeem siv los kho qhov ceev. Feem ntau, qhov sib txawv ntawm qhov ceev ntawm lub cev yog txwv tsis pub kim, thiab kev hloov kho vane yuav tsum tsuas yog siv thaum kev tshawb fawb txog kev lag luam rau qhov xwm txheej tshwj xeeb rau nws.
5. Cov khoom siv cua: muab cua rau qhov chaw nqus ntawm lub raj xa dej kuj yog ib txoj hauv kev kho tus nqi ntws, uas tuaj yeem txuag tau qee lub zog piv nrog lub qhov hluav taws xob throttling. Feem ntau, lub xub ntiag ntawm huab cua nyob rau hauv cov kua xa tawm tsis xav tau, thiab huab cua ntau dhau ib txwm ua rau muaj kev pheej hmoo ntawm lub twj tso kua mis poob nws lub taub hau priming, yog li txoj kev no tsis tshua muaj siv hauv kev xyaum tshwj tsis yog hauv cov xwm txheej cais.
