Centrifugal pombi inoshandiswa zvakanyanya mukuchengetedza mvura, indasitiri yemakemikari nemamwe maindasitiri, kusarudzwa kwenzvimbo yayo yekushandisa uye kuongororwa kwekushandiswa kwesimba kuri kuwedzera kukosha. Iyo inonzi nzvimbo yekushanda, inoreva pombi yepombi mune imwe nguva chaiyo inobuda mvura, musoro, shaft simba, kunyatsoita uye suction vacuum urefu, nezvimwewo, inomiririra kugona kushanda kwepombi. Kazhinji, iyo centrifugal pombi inoyerera, yekumanikidza musoro inogona kunge isingaenderane neyepombi system, kana nekuda kwebasa rekugadzira, nzira inoda shanduko, kudiwa kwekudzora kuyerera kwepombi, hunhu hwayo kushandura centrifugal pombi yekushanda. Pamusoro peiyo engineering dhizaini nhanho yekusarudzwa kwepombi yecentrifugal kwakaringana, iko iko kushandiswa kwecentrifugal pombi yekushandisa kunozokanganisa zvakananga kushandiswa kwesimba remushandisi uye mutengo. Naizvozvo, nzira yekushandura zvine musoro iyo centrifugal pombi inoshanda nzvimbo inonyanya kukosha. Nzvimbo yekushanda yepombi ye centrifugal inobva pachiyero pakati pekupa uye kudiwa kwesimba repombi uye hurongwa hwepombi. Chero bedzi imwe yemamiriro maviri aya ichichinja, nzvimbo yekushanda ichachinja. Kuchinja kwenzvimbo yekushanda kunokonzerwa nezvikamu zviviri: kutanga, kuchinja kwepiping system characteristic curve, yakadai sevhavha throttling; Chechipiri, hunhu hwepombi yemvura pachayo curve shanduko, senge frequency kutendeuka kumhanya, kucheka impeller, pombi yemvura inoteedzana kana parallel.

Nzira dzinotevera dzinoongororwa nekuenzaniswa:
Kuvharwa kwevhavha: nzira iri nyore yekushandura centrifugal pombi inoyerera ndeyekugadzirisa kuvhurwa kwepombi yekubuda, uye kumhanya kwepombi inoramba isina kuchinjika (kazhinji yakayerwa kumhanya), musimboti wayo kushandura chinzvimbo chepombi maitiro curve kushandura pombi inoshanda. point. Kana vharuvhu ichidzimwa, kupikisa kwepanzvimbo yepombi kunowedzera uye nzvimbo yekushanda yepombi inofamba kuruboshwe, nokudaro kuderedza kuyerera kunoenderana. Kana iyo valve yakavharwa zvachose, yakaenzana nekusingaperi kusagadzikana uye zero kuyerera. Panguva ino, iyo pombi yehunhu curve inopindirana neiyo vertical coordinate. Kana vharuvhu yakavharwa kuti idzore kuyerera, simba rekupa mvura yepombi pachayo rinoramba risingachinji, maitiro ekusimudza anoramba asina kuchinjika, uye hunhu hwekupikisa pombi huchachinja nekushandurwa kwekuvhura kwevhavha. Iyi nzira iri nyore kushanda, inoenderera ichiyerera, inogona kugadziridzwa pakuda pakati peimwe yakanyanya kuyerera uye zero, uye hapana yekuwedzera mari, inoshanda kune dzakasiyana siyana dzezviitiko. Asi throttling regulation ndeyekushandisa simba rakawandisa repombi ye centrifugal kuchengetedza humwe huwandu hwekugovera, uye kushanda kwepombi ye centrifugal kuchadererawo, izvo zvisina musoro mune zvehupfumi.

Variable frequency speed regulation uye kutsauswa kwenzvimbo yekushandira kubva pakakwirira kunyatsoshanda zone ndiwo mamiriro ekutanga epombi yekumhanya kudzora. Kana pombi yepombi ichichinja, kuvhurika kwevharuvhu kunoramba kwakafanana (kazhinji kuvhura kwakanyanya), maitiro epombi system anoramba akafanana, uye simba rekupa mvura uye hunhu hwekusimudza hunochinja zvinoenderana.
Muchiitiko chekuyerera kunodiwa kuduku kudarika kwakarongwa, musoro wekusiyana-siyana wekugadzirisa kukurumidza kukurumidza kuduku kudarika valve throttling, saka kudiwa kwekusiyana kwemaitiro ekumhanya kwekugadzirisa simba rekupa mvura iduku kudarika valve throttling. Zviripachena, kana zvichienzaniswa nevharuvhu throttling, frequency kutendeuka kukurumidza saving effect yakakurumbira, centrifugal pombi kushanda zvakanaka kwakakwira. Mukuwedzera, kushandisa variable frequency speed regulation, haisi kungobatsira chete kuderedza dambudziko rekugadzira cavitation mu centrifugal pombi, uye inogona kudzorwa neacc / dec nguva yekuwedzera preset kutanga / kumira, nokudaro kuderedza zvikuru torque ine simba, saka yakabviswa inosiyana zvakanyanya uye inoparadza mvura sando mhedzisiro, inowedzera zvakanyanya hupenyu hwepombi uye pombi system.

Muchokwadi, frequency conversion speed regulation inewo painogumira, kunze kwekudyara kukuru, mari yekuchengetedza yakakwirira, apo pombi yekumhanya ichave yakakura kwazvo ichakonzera kuderera kwehunyanzvi, kupfuura chiyero chepombi proportional law, hazvibviri kukurumidza kusingagumi.

Kucheka impeller: kana kumhanya kuri kwechokwadi, iyo pombi yekumanikidza musoro, kuyerera uye impeller dhayamita. Kune imwechete yemhando yepombi, nzira yekucheka inogona kushandiswa kushandura maitiro epombi curve.

Mutemo wekucheka unobva pane nhamba huru ye data yekuongorora, inofunga kuti kana chiyero chekucheka chemuputi chinodzorwa mukati meimwe muganhu (muganho wekucheka unoenderana nekushanduka kwakananga kwepombi), ipapo kushanda kwakafanana kwepombi. pombi isati yasvika uye mushure mekucheka inogona kuonekwa seisina kuchinjwa. Kucheka impeller inzira iri nyore uye iri nyore yekushandura mashandiro epombi yemvura, ndiko kuti, iyo inonzi inoderedza dhayamita kugadziriswa, iyo kune imwe nhanho inogadzirisa kupokana pakati pemhando shoma uye kutsanangurwa kwepombi yemvura uye kusiyanisa kwemvura. chinhu chinodiwa, uye inowedzera chiyero chekushandiswa kwepombi yemvura. Zvechokwadi, impeller yekucheka inzira isingadzoki; mushandisi anofanirwa kuverengerwa nemazvo uye kuyerwa kusati kwaitwa hungwaru hwehupfumi.

Series parallel: pombi yemvura inotevedzana inoreva kubuda kwepombi kuenda kunopinza kweimwe pombi kutamisa mvura. Mumhando mbiri dzakareruka dzakafanana uye kuita kwakafanana kwecentrifugal pombi yakatevedzana, semuenzaniso: mutsara wekuita curve yakaenzana nepombi imwechete yekuita curve yemusoro pasi pekuyerera kwakafanana, uye kuwana nhevedzano yekuyerera uye musoro zvakakura kupfuura. pombi imwe yekushanda pombi B, asi ipfupi pombi imwechete kaviri saizi ye, izvi imhaka yekuti pombi yakatevedzana kune rimwe ruoko, kuwedzera kwekusimudza kwakakura kupfuura kuramba kwepombi kunowedzera, kusara kwekusimudza simba kuyerera kunowedzera, kuwedzera kwekuyerera uye kuwedzera kupikisa kune rumwe rutivi, kudzivisa kuwedzera kwemusoro wose. , pombi yemvura yakatevedzana oparesheni, inofanirwa kutarisisa kune yekupedzisira pombi inogona kutsungirira kuwedzera. Pamberi pekutanga kwevhavha yega yega yepombi inofanira kuvharwa, uye ipapo kutevedzana kwekuzarura pombi nevharuvhu kuti ipe mvura.

Pombi yemvura parallel zvinoreva mapombi maviri kana anopfuura maviri kune imwechete yekumanikidza pombi kuendeswa kwemvura; chinangwa chayo ndechekuwedzera kuyerera mumusoro mumwechete. Zvichiri mune yakanyanya kupfava yemhando mbiri dzakafanana, yakafanana centrifugal pombi yakafanana semuenzaniso, kuita kweparallel performance curve yakaenzana neyepombi imwechete yekuita curve yekuyerera pasi pemamiriro emusoro yakaenzana nepamusoro, kugona uye. Musoro weparallel working point A wanga wakakura pane imwe pombi yekushanda pombi B, asi funga nezvepombi resistance factor, zvakare ipfupi pombi imwechete ka2.

Kana chinangwa chiri chekuwedzera mwero wekuyerera, saka kuti kushandisa parallel kana nhevedzano kunofanirwa kuenderana nekupfava kwepipeline hunhu curve. Iyo inopfavira iyo pombi maitiro emhando yecurve ndeye, iyo yakawanda yekuyerera kweyero mushure mekufanana iri pedyo nekaviri iyo yepombi imwe chete kushanda, kuitira kuti kuyerera kunopfuura kweiyo munhevedzano, iyo inonyanya kubatsira kushanda.

Mhedziso: Kunyange zvazvo kuputika kwevharuvhu kuchigona kukonzera kurasikirwa kwesimba uye kupera, ichiri nzira inokurumidza uye iri nyore yekudzora kuyerera mune dzimwe nguva dziri nyore. Frequency yekushandura yekumhanyisa regulation iri kuwedzera kufarirwa nevashandisi nekuda kweyakanaka simba rekuchengetedza simba uye yakakwirira degree re automation. Kucheka impeller kunowanzoshandiswa pakuchenesa pombi yemvura, nekuda kwekuchinja kwechimiro chepombi, iyo yakawanda haina kunaka; Pombi yakatevedzana uye parallel inokodzera chete pombi imwe chete haigone kusangana nebasa rekufambisa mamiriro, uye nhevedzano kana kuenzanisa yakawandisa asi kwete yehupfumi. Mukushandisa kunoshanda, isu tinofanirwa kufunga kubva kune akawanda maficha uye kubatanidza yakanakisa chirongwa munzira dzakasiyana dzekuyerera kuyerera kuti tive nechokwadi chekushanda kwakanaka kwepombi yecentrifugal.
