1. Qhov hluav taws xob throttling: Rau cov twj tso kua mis uas muaj qhov ceev thiab nruab nrab, qhov no yog ib qho kev hloov pauv uas tsis tshua muaj nqi. Throttling mus rau qhov chaw tuag yuav ua rau cov kua hauv lub twj tso kua mis overheat. Koj tuaj yeem siv lub bypass los tswj qhov tsim nyog ntws, lossis siv cov kev hloov pauv sib txawv. Qhov no yog qhov tseem ceeb heev rau cov twj uas tau hais los saum toj no uas tuav cov dej kub lossis cov kua dej tsis haum.
2. Throttle ntawm qhov chaw nres nkoj suction: Yog tias muaj NPSH txaus muaj, qee lub zog tuaj yeem txuag tau los ntawm throttling hauv txoj kab nqus. Vim tias qhov hluav taws xob throttling tuaj yeem ua rau muaj cua sov los yog vaporization ntawm cov kua, lub dav hlau cav roj pipeline twj feem ntau siv inlet throttling. Ntawm qhov tsawg txaus txaus, 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 ntawm 1/30 ntawm tag nrho cov haujlwm ntawm lub impeller thaum lub qhov hluav taws xob throttling. Tus nqi ntws ntawm lub twj tso kua mis condensate feem ntau yog tswj los ntawm qhov tob tob. Sib npaug rau inlet throttling. Cov qauv tsim tshwj xeeb tuaj yeem txo qhov kev puas tsuaj ntawm cov twj tso kua mis no mus rau qhov tsis tseem ceeb, tab sis lub zog theem kuj tau qis heev.
3. Kev hloov kho bypass: tag nrho lossis ib feem ntawm cov dej ntws tuaj yeem muab faib thiab tso tawm los ntawm cov pa 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 qhov ntws ntawm lub boiler pub twj tso kua mis, feem ntau los tiv thaiv overheating. Yog tias cov dej ntws ntau dhau ntawm lub tshuab raj bypass siv los hloov lub qhov hluav taws xob qhov hluav taws xob, lub zog loj tuaj yeem cawm tau.
4. Kev hloov kho ceev: Thaum siv txoj kev no los kho qhov ntws, lub zog yuav tsum tau txo kom tsawg, thiab qhov tshwm sim ntawm overheating nyob rau hauv cov txheej txheem kev khiav dej num yuav raug tshem tawm. Chav turbines thiab combustion engines tuaj yeem hloov tau yooj yim rau kev tswj ceev nrog tus nqi me me ntxiv. Ntau yam khoom siv hluav taws xob, sib nqus, hydraulic ceev hloov khoom siv thiab DC thiab AC hloov pauv ceev motors tuaj yeem siv los kho qhov ceev. Feem ntau, kev hloov pauv ceev ntawm lub cev muaj zog yog kim dhau, thiab kev kho cov hniav tuaj yeem siv tau tsuas yog thaum cov kev tshawb fawb nyiaj txiag ntawm cov xwm txheej tshwj xeeb ua pov thawj tias tsim nyog.
5. Replenishing air: Replenishing air to the suction port of the pipeline pump is also a method to adjust the flow. Txoj kev no tuaj yeem txuag tau qee lub zog piv nrog lub qhov hluav taws xob throttling. Feem ntau, nws tsis tsim nyog kom muaj huab cua hauv cov kua thauj, thiab ib txwm muaj kev pheej hmoo ntawm lub twj tso kua mis poob nws lub taub hau yog tias muaj cua ntau dhau. Yog li ntawd, txoj kev no tsis tshua muaj siv hauv kev xyaum tshwj tsis yog qee lub sijhawm.
