Cishe zonke izici ezingena ekuphileni okuthembekile kwephampu zifika kumsebenzisi wokugcina, ikakhulukazi indlela iphampu esebenza futhi inakekelwa ngayo. Yiziphi izici umsebenzisi wokugcina angazilawula ukuze andise impilo yephampu? Izici ezilandelayo eziyi-13 ezibalulekile ziyizinto ezibalulekile zokucatshangelwa ukuze kunwetshwe impilo yephampu.

1. Amandla Emisebe

Izibalo zemboni zibonisa ukuthi imbangela enkulu yokungasebenzi kahle okungahleliwe kwamaphampu aphakathi nendawo ukuthwala kanye/noma ukuhluleka kokuvalwa komshini. Ama-Bearings kanye ne-seal "ama-canaries emayini yamalahle" - ayizinkomba zakuqala zempilo yepompo kanye nesandulela sokwehluleka ngaphakathi kohlelo lokumpompa. Noma ubani oke wasebenza embonini yepompo nganoma yisiphi ubude besikhathi cishe uyazi ukuthi umkhuba wokuqala ongcono kakhulu ukusebenzisa iphampu endaweni noma eduze kwe-Best Efficiency Point (BEP). Ku-BEP, iphampu iklanyelwe ukumelana namandla amancane e-radial. Uma isebenza kude ne-BEP, umphumela wevector yawo wonke amandla e-radial iku-engeli engu-90° ku-rotor futhi izama ukuphambukisa nokugoba i-pump shaft. Amandla e-radial aphezulu kanye nokuchezuka kwe-shaft okuwumphumela kuwumshini wokubulala uphawu futhi kuyisici esinomthelela ekufinyezweni kwempilo yokuzala. Uma amandla e-radial emakhulu ngokwanele, angabangela ukuthi i-shaft iphambuke noma igobe. Uma umisa iphampu futhi ulinganise ukuphuma kwe-shaft, ngeke uthole lutho olungalungile ngoba lesi yisimo esiguqukayo, hhayi esimile. Ishafti egobile egijima ngo-3,600 rpm izochezuka kabili ngokuphenduka ngakunye, ngakho-ke izogoba izikhathi ezingu-7,200 ngomzuzu. Lokhu kuchezuka komjikelezo ophezulu kwenza kube nzima ukuthi ubuso be-seal bugcine ukuxhumana nokugcina ungqimba lwamanzi (ifilimu) oludingekayo ukuze uphawu lusebenze kahle.

2. Ukungcoliswa kwamafutha

Ngama-ball bearings, ngaphezu kwe-85% yokwehluleka ukuthwala kubangelwa ukungcoliswa, okungaba uthuli nodaba lwangaphandle noma amanzi. Izingxenye ezingu-250 nje esigidini ngasinye (ppm) zamanzi zinganciphisa ukuphila okuthwalayo ngesilinganiso samane. Impilo yamafutha ibalulekile.

3. Ingcindezi Yokudonsa

Ezinye izici eziyinhloko ezithinta ukuphila kokuzala zihlanganisa ukucindezela kokumunca, ukuqondanisa komshayeli, kanye nokuqina kwepayipi ngezinga elithile. Ku-ANSI B 73.1 yesigaba esisodwa samaphampu enqubo yokweqa okuvundlile, amandla e-axial akhiqizwe ku-rotor abheke embobeni yokudonsa, ngakho-ke ngokwezinga elithile nangaphakathi kwemikhawulo ethile, ukucindezela kokudonsa kokusabela kuzonciphisa amandla e-axial, ngaleyo ndlela kunciphise imithwalo ethwala i-thrust. kanye nokwelula impilo yeamaphampu eturbine ajulile kahle.

4. Ukuqondisa Umshayeli

Ukungalungi kahle kwepompo nomshayeli kungalayisha kakhulu i-radial bear. Impilo ye-radial bear ihlobene kakhulu nezinga lokungaqondani kahle. Isibonelo, ngokungahambi kahle okuncane (ukungalungi kahle) okungamayintshi angu-0.060 kuphela, umsebenzisi wokugcina angase ahlangabezane nezinkinga zokuzala noma zokuhlanganisa ngemva kwezinyanga ezintathu kuya kweziyisihlanu zokusebenza. Nokho, uma ukungaboni ngaso linye kungu-0.001 amayintshi, iphampu efanayo ingase isebenze ngaphezu kwezinyanga ezingu-90.

5. I-Pipe Strain

Ubunzima bepayipi kubangelwa ukungahambi kahle kwamapayipi okumunca kanye/noma akhiphayo ngama-flange epompo. Ngisho nasekwakhiweni kwephampu eqinile, uhlobo lwamapayipi lungadlulisela kalula lezi zingcindezi ezingase zibe phezulu kumabheringi kanye nokulingana kwazo kwezindlu ezihambisanayo. Amandla (i-strain) angabangela ukuthi i-bearing fit iphume nxazonke kanye/noma ingahambisani namanye ama-bearings, okubangela ukuthi imigqa emaphakathi ibe ezindizeni ezahlukene.

6. Izakhiwo Zamanzi

Izakhiwo eziwuketshezi njenge-pH, i-viscosity, namandla adonsela phansi athile yizici ezibalulekile. Uma uketshezi lune-asidi noma lugqwala, ukugeleza kwezingxenye ze-a iphampu ye-turbine ejulile kahle njengomzimba wepompo kanye ne-impeller kumele imelane nokugqwala. Okuqukethwe okuqinile koketshezi kanye nobukhulu balo, ukwakheka, kanye nokuhubeka konke kuyizici.

7. Imvamisa Yokusebenzisa

Ukuvama kokusetshenziswa kungenye into ebalulekile: Ipompo iqala kangaki esikhathini esithile? Ngizibonele mathupha amaphampu aqala futhi ame njalo ngemizuzwana embalwa. Izinga lokuguga kulawa maphampu liphakeme kakhulu kunalapho iphampu isebenza ngokuqhubekayo ngaphansi kwezimo ezifanayo. Kulokhu, umklamo wesistimu udinga ukushintshwa.

8. I-Net Positive Suction Head Margin

Ubukhulu bemajini phakathi kwe-Net Positive Suction Head Available (NPSHA, noma i-NPSH) kanye ne-Net Positive Suction Head Iyadingeka (NPSHR, noma i-NPSH edingekayo), mancane amathuba okuba nomthombo ojulile. iphampu ye-turbine eqondile izoba yi-cavitate. I-Cavitation ilimaza i-impeller yepompo, futhi ukudlidliza okubangelwayo kungathinta impilo yezimpawu nama-bearings.

9. Isivinini sepompo

Ijubane lapho iphampu lisebenza khona lingesinye isici esibalulekile. Isibonelo, iphampu egijima ku-3,550 rpm izogqoka ngokushesha ngokuphindwe kane kuya kweziyisishiyagalombili kuneyodwa egijima ku-1,750 rpm.

10. I-Impeller Balance

Ama-impeller angalinganiseli kumaphampu e-cantilever noma imiklamo ethile eqondile ingabangela ukugoqa kwe-shaft, isimo esichezukisa i-shaft, njengamandla e-radial lapho iphampu ibaleka ku-BEP. Ukuchezuka kwe-radial nokugegetheka kwe-shaft kungenzeka ngesikhathi esisodwa.

11. Ukuhlelwa Kwepayipi kanye Nezinga Lokugeleza Kokungena

Okunye okucatshangelwayo okubalulekile ekunwebeni impilo yephampu ukuthi amapayipi ahlelwa kanjani, okungukuthi ukuthi uketshezi "lulayishwa" kanjani epompo. Isibonelo, indololwane endizeni eqondile ohlangothini lokumunca lwephampu izoba nemiphumela elimazayo encane kunendololwane evundlile - ukulayishwa kwe-hydraulic kwe-impeller kuyalingana, ngakho-ke ama-bearings alayishwa ngokulinganayo.

12. Pump Operating Temperature

Izinga lokushisa elisebenzayo lephampu, noma liyashisa noma liyabanda, futhi ikakhulukazi izinga lokushisa lokushintsha kwezinga lokushisa, lingaba nomthelela omkhulu empilweni nasekuthembekeni kwephampu yeturbine ejulile emile. Izinga lokushisa lokusebenza kwepompo libaluleke kakhulu futhi iphampu kufanele yakhelwe ukuhlangabezana nezinga lokushisa lokusebenza. Kodwa okubaluleke nakakhulu izinga lokushisa lokushintsha.

13. Ukungena kwe-Pump Casing

Nakuba kungavamile ukucatshangelwa, isizathu sokuthi ukungena kwe-pump casing kuyinketho esikhundleni sezinga lamaphampu e-ANSI ukuthi inani lokungena kwe-pump casing lizoba nomthelela othile empilweni yephampu, njengoba lezi zindawo ziyizindawo eziyinhloko zokugqwala nokugqwala. i-stress gradients (ikhuphuka). Abasebenzisi abaningi bokugcina bafuna ukuthi i-casing ibhojwe futhi ithintwe ukuze kukhishwe amanzi, ukuqeda amandla, izimbobo zezinsimbi. Ngaso sonke isikhathi lapho imbobo ibhobolwa futhi ishaywa egobolondweni, i-gradient yokucindezeleka ishiywa ezintweni, okuba umthombo wokuqhekeka kwengcindezi nendawo lapho ukugqwala kuqala khona.

Okungenhla okwereferensi yomsebenzisi kuphela. Ngemibuzo ethile, sicela uthinte i-CREDO PUMP.
