Ayingobemi kuphela abanamakhadi esazisi, kodwa neempompo zamanzi, ezikwabizwa ngokuba “zii-nameplates”. Zeziphi iinkcukacha ezahlukeneyo kwiipleyiti zegama ezibaluleke ngakumbi, kwaye sifanele siqonde kwaye simbe njani ulwazi lwabo olufihliweyo?
01 Igama lenkampani
Igama lenkampani luphawu lweemveliso kunye neenkonzo. Sinokusebenzisa olu lwazi ukujonga ukuba ngaba inkampani inazo iziqinisekiso zemveliso ezihambelanayo kumaqumrhu esiqinisekiso soshishino esifanelekileyo ukubonisa ubuni nokuthembeka komenzi wempompo yamanzi. Umzekelo: Isiqinisekiso senkqubo yolawulo lomgangatho we-ISO, isiqinisekiso selungelo elilodwa lomenzi wechiza, njl.njl.
Ukufumana olu lwazi kuya kusinceda siqonde imeko yenkampani yokuvelisa kwaye sibe neqondo elithile lokuzithemba kumgangatho wemveliso. Okukhona ikumgangatho ophezulu inkampani, kokukhona iphezulu inqanaba lenkonzo iyonke, kwaye inkonzo yasemva kokuthengisa kubasebenzisi nayo iqinisekisiwe.
02 imodeli
Imodeli yempompo yamanzi iqulethe umtya weeleta kunye namanani, amele ulwazi olufana nohlobo kunye nobukhulu bompompo wamanzi. Umzekelo, i-QJ yimpompo yombane engaphantsi kwamanzi, i-GL yimpompo ye-centrifugal enenqanaba elinye, kwaye i-JYWQ yimpompo yogutyulo oluzenzekelayo oluyaluza.
Njengoko kuboniswe kumzobo ongezantsi: inombolo "i-65" emva kweleta ye-PZQ imele "i-diameter ye-pump inlet", kunye neyunithi yayo mm. Ichaza ububanzi bombhobho odibanisayo kwaye inokusinceda sifumane umbhobho ofanelekileyo wokudibanisa kwindawo yokungena amanzi.
Ithetha ukuthini i-“50″ emva kuka-“80”? Lithetha "i-diameter yegama le-impeller", kwaye iyunithi yayo yi-mm, kwaye owona bubanzi be-impeller buya kumiselwa ngokokuhamba kunye nentloko efunwa ngumsebenzisi."7.5″ ithetha amandla emoto, emele i Amandla aphezulu anokuthi i-motor isebenze ixesha elide phantsi kombane olinganisiweyo. Iyunithi yayo yi-kilowatts. Okukhona umsebenzi owenziwayo ngexesha leyunithi, kokukhona amandla makhulu.
03 ukuhamba
Isantya sokuhamba yenye yedatha ebalulekileyo yereferensi xa ukhetha impompo yamanzi. Ibhekisa kumyinge wolwelo oluhanjiswa yimpompo ngexesha leyunithi. Olona nqanaba lokuqukuqela esilidingayo xa sikhetha impompo yamanzi ikwangomnye wemigangatho yereferensi. Umlinganiselo wokuhamba awukho mkhulu kangangoko. Ukuba inkulu okanye incinci kunobungakanani obufunekayo obufunekayo, iya kwandisa ukusetyenziswa kwamandla kwaye ibangele inkcitho yemithombo.
04 intloko
Intloko yempompo inokuqondwa ngokulula njengobude apho impompo inokumpompa amanzi, iyunithi ngu-m, kwaye intloko yohlulwe ibe yintloko yokufunxa amanzi kunye nentloko yokukhupha amanzi. Intloko iyafana nokuhamba kwempompo, iphakamileyo ingcono, ukuhamba kwempompo kuya kuncipha ngokunyuka kwentloko, ngoko ke intloko ephezulu, incinci, kwaye incinci ukusetyenziswa kwamandla. Ngokuqhelekileyo, intloko yempompo yamanzi imalunga ne-1.15 ~ 1.20 amaxesha okuphakama kwamanzi.
05 I-NPSH efunekayo
I-NPSH eyimfuneko ibhekiselele kumlinganiselo ophantsi wokuhamba kwamanzi apho ulwelo lusenokuthi luhambe ngokuqhelekileyo xa ukuguga kunye nokudleka kodonga lwangaphakathi lombhobho lufikelela kwinqanaba elithile ngexesha lokuhamba kolwelo. Ukuba izinga lokuhamba lingaphantsi kweNPSH efunekayo, i-cavitation iyenzeka kwaye umbhobho uyahluleka.
Ukuyibeka ngokulula, ipompo ene-cavitation allowance ye-6m kufuneka ibe nentloko ubuncinane ye-6m yekholomu yamanzi ngexesha lokusebenza, ngaphandle koko i-cavitation iya kwenzeka, yonakalise umzimba wempompo kunye ne-impeller, kwaye inciphise ubomi benkonzo.

06 Inombolo yemveliso/umhla
Inombolo kunye nomhla zikwangumthombo ongundoqo wolwazi lokulungiswa kwempompo ye-aftermarket kunye nokugcinwa. Ngolu lwazi, unokufumana ulwazi olubalulekileyo olunje ngeendawo zokuqala zempompo, incwadana yokusebenza, ubomi benkonzo, umjikelo wokulondoloza, njl. .
Isiphelo: I-nameplate yempompo yamanzi ifana nekhadi lesazisi. Sinokuyiqonda inkampani kwaye sibambe ulwazi lwemveliso nge-nameplate. Sinokuqinisekisa amandla ebhrendi kwaye sifumanise ixabiso lemveliso ngemveliso.
Thanda kwaye ulandeleUbunyuluIshishini lempompo ukufunda ngakumbi malunga neepompo zamanzi ngokulula.
