Hunhu hwekutenderera kwepombi-pombi kune hukama pakati pepombi (kureva kuti simba rekupomba) uye kuyerera kweWell.duite kunounza kutsanangurwa kwakadzama

• Hunhu hwekutenderera kwe centrifugal pombi

Musoro, kuyerera, simba uye kushanda zvakanaka ndiwo mafungiro makuru emapapeti e centrifugal pombi. Ukama huri pakati peiyi paramita dzinogona kutsanangurwa nekuedza. Iyo centrifugal pombi yekugadzira Dhipatimendi inoshandisa iyo curve yeakakosha perform parameter yezvigadzirwa zvayo, uye aya ma curves anonzi hunhu hwehurumende ye centrifugal pombi. Zvekureva kushandiswa kwemapombi uye mashandiro ekushandiswa kwedhipatimendi.

Iyo yehunhu curve inoedzwa pasi pekumhanya kwakarongedzwa, uye zvakangoerekana zvaita kuti kumhanya. Naizvozvo, kukosha kwekumhanya n kunoratidzwa pane hunhu curve yemepu. Mufananidzo 2-6 ndiyo imba yepamusoro 4b20 centrifugal pump kana n = 2900r / min feica. Essence pane matatu curves pamufananidzo

1. H -Q Curve

Iyo H -Q curve inoratidza hukama pakati peiyo kuyerera Q uye musoro wePombi uye muchina weChinjanidzo yeCentrifugal pombi yakawedzera mukati meiyo hombe yekuyerera. Mhando dzakasiyana dze centrifugal pumps ine maumbirwo akasiyana eH -Q curve. Kana mamwe ma curves ari pasi, zvakakodzera kuti zviitiko zvidiki zvine shanduko midiki mumusoro uye hukuru hwekuyerera; Mamwe ma curves ari akanyura, uye akakodzera kuti nguva nekuchinja kukuru mumusoro wemusoro pasina kubvumira shanduko dzemigwagwa.

2. N -Q curve

Iyo N -Q curve inoratidza hukama pakati peiyo kuyerera Q uye axis simba n ye pombi, uye nyoka inowedzera, kana q = 0, iyo Simba rekushandisa pombi yepombi ndeyekupedzisira. Naizvozvo, kana uchitanga pombi yezentrifugal, kuitira kuti uderedze simba rekutanga, vharuvhu rinofanira kuvharwa.

3. Η -q curve

-Q curve inomiririra hukama pakati peiyo kuyerera q uye kushanda kwepombi. Pakutanga, yakawedzera nekuwedzera kweQ, uye mushure mekusvika pakanyanya kukosha, yakadzikira nekuwedzera kweQ. kukosha kwakanyanya kweiyo curve iyi yakaenzana neyakanyanya kunaka. Iyo pombi inoshanda kune inoenderana kumanikidza musoro uye traffic yeiyi pfungwa, uye kushanda kwayo ndiko kwakanyanya. Saka iyi poindi ndiyo gadziriro yekugadzira ye centrifugal pombi. Kana uchisarudza pombi, ini ndinogara ndichitarisira kuti pombi iri kushanda nekukwira kwakanyanya, nekuti kuvhiya ndiyo hupfumi hwakawanda pasi pemamiriro ezvinhu aya. Nekudaro, kutaura idi, mapapipi anowanzoita kuti ashandire pasi pemamiriro ezvinhu aya. Naizvozvo, zvinowanzo kuve madikanwa kuti utaure chiyero chebasa, inonzi nzvimbo yakakwirira yekubudirira yepombi, sezvakaratidzwa mumufananidzo 2-6 mitsetse mitsetse. Kubudirira kwemazwi akakwirira -Elicercy zoni hakufanirwe kunge kushoma pane 92% yekubudirira kwakanyanya. Pumps ese akaiswa chiratidzo pane iyo complate, musoro, musoro uye simba pakubata kwakanyanya. Iyo centrifugal pombi yechigadzirwa chechigadzirwa uye mirayiridzo zvakare kazhinji inoratidza kuyerera kwetraffic, musoro uye simba renzvimbo yepamusoro yekunyora nzvimbo.

• Kukanganiswa kwekutenderera kwe centrifugal pombi pane hunhu curve

Hunhu hwekutenderera kwe centrifugal pombi inotsunga kune imwe kumhanya. Kana kumhanya kwacho kuchichinjwa kubva kuN1 kusvika kuN2, iyo yekuyamwa kwekuyerera, musoro, uye simba resimba riri

Formula (2-6) inonzi mutemo wehuwandu. Kana shanduko yekumhanyisa isingasviki 20%, kugona kunogona kufungwa nezvisina kuchinjika, uye kukanganisa kwekuverenga hakuna kukura.

• Pesvedzero yemhando yemuviri

Hunhu hwehunhu hwakapihwa nedhipatimendi rekugadzira pombi rinowanikwa nemvura yekuedza. Kana chimiro chemvura inotakurwa iri hombe uye mvura yakakura, mhedzisiro yeViscosity uye density pane hunhu curves dzinofanirwa kutariswa.

1. Mhedzisiro yeViscosity:

Iyo yakakura iyo visikopa yemvura inotakurwa, iyo yakawanda simba mundiro yemapomba. Semhedzisiro, kudzvinyirira musoro uye kuyerera kwepombi kunofanirwa kuderedzwa, kugona kunoderera, uye simba reAxis rinofanira kuwedzera, saka hunhu hwekudzora.

2. Chikonzero chekushambadzira:

Iyo yakadzvanywa musoro wepombi yeCentrifugal haina chekuita nehuremu, iyo inogona kutsanangurwa concepent. Pane imwe kumhanya, iyo centrifugal simba inoenderana nekuwedzera kwemvura. Nekudaro, kudzvinyirira kwemvura nekuda kwemhedzisiro yeCentrifugal simba kwakaenzana nekumanikidza kwakaumbwa neyekumanikidza kwekunze kweiyo its, uyezve iyo yakawanda yekuwedzera kweiyo density uye kukwidziridzwa kwemvura uye kukwirisa kwakakura. Mhedzisiro yekudzimba mumusoro inobviswa. Nekudaro, iyo axis simba repombi shanduko nehurema hwemvura. Naizvozvo, apo density yemvura yekufambisa isiri panguva imwe chete semvura, iyo n-q curve yakapihwa ne pombi haigone kushandiswa,

3. Chikonzero chekushamisira:

Kana iyo iyo yekufambisa mvura isimbiso yemvura, shanduko yekushongedza ichave inokanganisa zvevasokisi uye density yemvura. Iyo yepamusoro pokusangana, iyo yakakura musiyano kubva kumvura. Mhedzisiro yekuisa pfungwa pane hunhu hwehunhu hwe centrifugal pombi inoratidzwawo muViscosity uye density. Kana iyo yekufambisa yemvura ine zvinhu zvakasimba sekumiswa, iyo pombi yemapomba inokanganiswawo nerudzi rwezvinhu zvakasimba uye kugoverwa kwegraurality mukuwedzera pakuwedzera.

Ruite pombi ine nyanzvi yeboka, inogona kubatsira mutengi kuwana pombi chaiyo nemutengo wehupfumi hwakanyanya.
