1. I-NPSHA Engaqondakali

Into ebaluleke kakhulu i-NPSHA yepompo yokudonsa kabili. Uma umsebenzisi engayiqondi kahle i-NPSHA, iphampu izokwenza i-cavitate, ibangele umonakalo obiza kakhulu kanye nesikhathi sokuphumula.

2. Iphuzu Elingcono Kakhulu Lokusebenza

Ukugijimisa iphampu kude ne-Best Efficiency Point (BEP) inkinga yesibili evamile ethinta amaphampu adonsa kabili. Ezicelweni eziningi, akukho okungenziwa mayelana nesimo ngenxa yezimo ezingaphezu kwamandla omnikazi. Kodwa kuhlale kukhona othile, noma isikhathi esifanele, sokucabangela ukushintsha okuthile ohlelweni ukuze kuvunyelwe iphampu ye-centrifugal ukuthi isebenze endaweni eklanyelwe ukusebenza kuyo. Izinketho eziwusizo zihlanganisa ukusebenza kwejubane eliguquguqukayo, ukulungisa i-impeller, ukufaka iphampu yosayizi ohlukile noma imodeli yepompo ehlukile, nokuningi.

3. Ukuxineka Kwepayipi: I-Silent Pump Killer

Kubonakala sengathi i-ductwork ngokuvamile ayiklanywanga, ayifakiwe noma ifakwe ihange ngendlela efanele, futhi ukunwetshwa nokuncipha kwe-thermal akucatshangelwa. I-Pipe strain iyimbangela esolwa kakhulu yezinkinga zokuzala kanye ne-seal. Isibonelo: ngemva kokuba siyalele unjiniyela osendaweni ukuthi asuse amabholothi esisekelo sephampu, iphampu yethani elingu-1.5 yaphakanyiswa ipayipi ngamashumi amamilimitha, okuyisibonelo sobunzima obukhulu bepayipi.

Enye indlela yokuhlola ukubeka inkomba yokudayela ekuhlanganiseni ezindizeni ezivundlile nezime mpo bese ukhulula ipayipi lokumunca noma lokukhipha. Uma inkomba yokudayela ibonisa ukunyakaza okungaphezu kuka-0.05 mm, ipayipi licindezelwe kakhulu. Phinda izinyathelo ezingenhla kwenye i-flange.

4. Qala Ukulungiselela

Amaphampu adonsa kabili anoma imuphi usayizi, ngaphandle kwamandla aphansi aqinile, amayunithi ephampu agibele phezulu, awavamile ukufika elungele ukuqala esizeni sokugcina. Iphampu ayiyona "ipulaki futhi idlale" futhi umsebenzisi wokugcina kufanele engeze uwoyela endlini ethwalayo, asethe i-rotor ne-impeller clearance, asethe uphawu lomshini, futhi enze ukuhlola kokuzungezisa kudrayivu ngaphambi kokufaka ukuhlanganisa.

5. Ukuqondanisa

Ukuqondanisa idrayivu empompini kubalulekile. Kungakhathaliseki ukuthi iphampu iqondaniswe kanjani efekthri yomkhiqizi, ukuqondanisa kungalahleka lapho iphampu ithunyelwa. Uma ipompo igxile endaweni efakiwe, ingase ilahleke lapho ixhuma amapayipi.

6. Izinga likawoyela kanye Nenhlanzeko

Amafutha amaningi ngokuvamile awangcono. Kumabhola amabheringi anezinhlelo zokuthambisa ze-splash, izinga elilungile likawoyela yilapho uwoyela uthintana naphansi kwebhola elingaphansi. Ukwengeza uwoyela owengeziwe kuzokhulisa ukungqubuzana nokushisa kuphela. Khumbula lokhu: Imbangela enkulu yokwehluleka ukuthwala ukungcoliswa kwamafutha.

7. Ukusebenza Kwephampu Eyomile

Ukucwiliswa emanzini (ukucwiliswa okulula) kuchazwa njengebanga elikalwa ngokuqondile ukusuka endaweni ewuketshezi ukuya emgqeni omaphakathi wembobo yokudonsa. Okubaluleke kakhulu ukucwiliswa kwamanzi okudingekile, okwaziwa nangokuthi ukucwiliswa okuncane noma okubucayi (SC).

I-SC ibanga eliqondile ukusuka endaweni ewuketshezi ukuya endaweni yokufaka iphampu yokumunca kabili edingekayo ukuze kuvinjelwe ukunyakaza koketshezi nokuzungezisa uketshezi. Isiyaluyalu singethula umoya ongafuneki namanye amagesi, angabangela ukulimala kwepompo futhi kunciphise ukusebenza kwepompo. Amaphampu ase-Centrifugal awawona ama-compressor futhi ukusebenza kungathinteka kakhulu lapho kuphampulwa uketshezi lwe-biphasic kanye/noma lwe-multiphase (ukungena kwegesi nomoya oketshezini).

8. Qonda Ingcindezi Ye-Vacuum

I-vacuum yisihloko esidala ukudideka. Lapho ubala i-NPSHA, ukuqonda okuphelele kwesihloko kubaluleke kakhulu. Khumbula, ngisho nasendaweni engenalutho, kukhona ingcindezi (ephelele) - kungakhathaliseki ukuthi incane kangakanani. Akuyona nje ingcindezi yomoya egcwele ojwayele ukuyazi ukuthi usebenza ezingeni lolwandle.

Isibonelo, phakathi nokubala kwe-NPSHA okubandakanya i-condenser yomhwamuko, ungase uhlangabezane ne-vacuum engu-28.42 amayintshi we-mercury. Ngisho ne-vacuum ephezulu kangaka, kusekhona ukucindezela okuphelele okungu-1.5 amayintshi we-mercury esitsheni. Ingcindezi engamayintshi angu-1.5 we-mercury ihumusha ekhanda eliphelele lamafidi angu-1.71.

Ingemuva: I-vacuum ephelele cishe ingamayintshi angu-29.92 we-mercury.

9. Faka indandatho kanye ne-Impeller Clearance

Ukugqokwa kwephampu. Lapho izikhala ziguga futhi zivuleka, zingaba nemiphumela engemihle empompini yokudonsa kabili (ukudlidliza namandla angalingani). ngokuvamile:

Ukusebenza kahle kwephampu kuzokwehla iphoyinti ngenkulungwane ngayinye ye-intshi (0.001) ekugqokeni kokucaciswa okungu-0.005 kuya ku-0.010 amayintshi (kusuka endaweni yokuqala).

Ukusebenza kahle kuqala ukwehla ngokuphawulekayo ngemva kokuba imvume igugile ifike ku-0.020 kuya ku-0.030 amayintshi ukusuka ekuvunyelweni kokuqala.

Ezindaweni zokungasebenzi kahle, iphampu imane inyakazise uketshezi, ama-bearings alimazayo kanye nezimpawu zenqubo.

10. I-Suction Side Design

Uhlangothi lokumunca luyingxenye ebaluleke kakhulu yepompo. Uketshezi alunawo amandla/amandla okuqina. Ngakho-ke, i-impeller yepompo ayikwazi ukunweba futhi idonse uketshezi empompo. Isistimu yokumunca kufanele inikeze amandla okuletha uketshezi epompo. Amandla angase aqhamuke namandla adonsela phansi kanye nekholomu emile yoketshezi ngaphezu kwephampu, umkhumbi/isitsha esicindezelekile (noma enye iphampu) noma nje asuka kumfutho womoya.

Izinkinga eziningi zephampu zenzeka ohlangothini lokudonsa lwephampu. Cabanga ngalo lonke uhlelo njengamasistimu amathathu ahlukene: isistimu yokumunca, iphampu ngokwayo, kanye nohlangothi olukhiphayo lwesistimu. Uma uhlangothi lokumunca lwesistimu lunikeza amandla oketshezi anele epompo, iphampu izobhekana nezinkinga eziningi ezenzeka ohlangothini lokuphuma lwesistimu uma ikhethwe kahle.

11. Ulwazi nokuqeqeshwa

Abantu abaseqophelweni eliphezulu kunoma yimuphi umsebenzi nabo bahlale belwela ukuthuthukisa ulwazi lwabo. Uma wazi ukuthi ungazifinyelela kanjani izinjongo zakho, iphampu yakho izosebenza kahle kakhulu nangokwethembeka.
