1. Matla a Radial

Lipalopalo tsa indasteri li bonts'a hore sesosa se seholo sa nako e sa reroang ea lipompo tsa centrifugal ke ho koala le/kapa ho hloleha ha tiiso ea mochini. Li-bearing le litiiso ke "li-canaries morafong oa mashala" - ke matšoao a pele a bophelo bo botle ba pompo le selelekela sa ho hloleha ka har'a sistimi ea pompo. Mang kapa mang ea sebelitseng indastering ea pompo ka nako e telele mohlomong oa tseba hore mokhoa oa pele o molemo ka ho fetisisa ke ho sebelisa pompo sebakeng kapa haufi le Best Efficiency Point (BEP). Ho BEP, pompo e etselitsoe ho mamella matla a fokolang a mahlaseli. Ha o sebetsa hole le BEP, sephetho sa matla a vector a matla ohle a radial a sekhutlong sa 90 ° ho rotor mme a leka ho kheloha le ho koba pompo ea pompo. Matla a phahameng a radial le ho kheloha ha shaft ke 'molai oa mochini oa litiiso ebile ke ntho e tlatsetsang ho khutsufatseng bophelo ba ho beleha. Haeba matla a mahlaseli a maholo ka ho lekaneng, a ka etsa hore shaft e khelohe kapa e kobehe. Haeba u emisa pompo 'me u lekanya ho phalla ha shaft, u ke ke ua fumana letho le phoso hobane sena ke boemo bo matla, eseng bo tsitsitseng. Shaft e kobehileng e mathang ka 3,600 rpm e tla kheloha habeli ka phetohelo, kahoo e tla kobeha makhetlo a 7,200 ka motsotso. Phapang ena e phahameng ea potoloho e etsa hore ho be thata ho lifahleho tsa tiiso ho boloka ho kopana le ho boloka lera la mokelikeli (filimi) e hlokahalang hore tiiso e sebetse hantle.

2. Tšilafalo ea Lubricant

Bakeng sa li-ball bearings, ho feta 85% ea ho beleha ho hlōleha ho bakoa ke tšilafalo, e ka ba lerōle le lintho tse tsoang linaheng tse ling kapa metsi. Likarolo tse 250 feela ho milione (ppm) tsa metsi li ka fokotsa bophelo bo belang ka karolo ea tse 'nè. Bophelo ba mafura bo bohlokoa.

3. Khatello ea ho hula

Lintlha tse ling tsa bohlokoa tse amang bophelo ba ho beleha li kenyelletsa khatello ea ho hula, ho tsamaisana le bakhanni, le ho ba le khatello e itseng ea lipeipi. Bakeng sa ANSI B 73.1-mohato o le mong oa lipompo tsa ts'ebetso tse holimo, matla a axial a hlahisoang ho rotor a lebile boema-kepe ba ho hula, kahoo ho isa bohōleng bo itseng le ka har'a meeli e itseng, khatello ea maikutlo e tla fokotsa matla a axial, ka tsela eo e fokotsa meroalo. le ho lelefatsa bophelo balipompo tsa turbine tse tebileng hantle tse otlolohileng.

4. Ho tsamaisana ha Mokhanni

Ho se tsamaisane hantle ha pompo le mokhanni ho ka kenya tšebetsong radial bearing. Bophelo ba "radial bearing" bo amana haholo le boemo ba ho se tsamaisane hantle. Ka mohlala, ka ho se lumellane ho fokolang (ho sa nepahale) ha lisenthimithara tse 0.060 feela, mosebedisi oa ho qetela a ka 'na a ba le mathata a ho beleha kapa a ho kopanya ka mor'a likhoeli tse tharo ho isa ho tse hlano tsa ts'ebetso. Leha ho le joalo, haeba karohano e fosahetseng e le 0.001 inches, pompo e tšoanang e ka sebetsa ho feta likhoeli tse 90.

5. Phala ea Pipe

Khatello ea lipeipi e bakoa ke ho se tsamaisane hantle ha lipeipi tse monyang le/kapa tse ntšang metsi ka li-flange tsa pompo. Leha e le ka moralo o matla oa pompo, khatello ea lipeipi e ka fetisetsa likhatello tsena tse phahameng habonolo ho li-bearings le ho lekana ha tsona. Matla (mathata) a ka etsa hore ho behoa ho lekaneng ho be ho pota-pota le / kapa ho se lumellane le li-bearings tse ling, ho etsa hore li-centerlines li be lifofaneng tse fapaneng.

6. Thepa ea Mokelikeli

Lintho tsa metsi tse kang pH, viscosity, le matla a khoheli a itseng ke lintlha tsa bohlokoa. Haeba mokelikeli o le asiti kapa o senya, phallo-ka likarolo tsa a pompo ea turbine e tebileng e otlolohileng hantle joalo ka 'mele oa pompo le impeller li hloka ho thibela kutu. Lintho tse tiileng tsa mokelikeli le boholo ba oona, sebōpeho sa oona, le ho khopama ha oona kaofela ke mabaka.

7. Khafetsa ea Tšebeliso

Khafetsa ea tšebeliso ke ntlha e 'ngoe ea bohlokoa: Pompe e qala hangata hakae ka nako e itseng? Ke bone ka bonna lipompo tse qalang le ho emisa metsotsoana e meng le e meng. Sekhahla sa ho roala lipompong tsena se phahame haholo ho feta ha pompo e ntse e sebetsa e sa khaotse tlas'a maemo a tšoanang. Tabeng ena, moralo oa tsamaiso o lokela ho fetoloa.

8. Net Positive Suction Head Margin

Ho na le moeli o moholo pakeng tsa Net Positive Suction Head Available (NPSHA, kapa NPSH) le Net Positive Suction Head E Hlokehang (NPSHR, kapa NPSH E Hlokehang), ha ho na monyetla oa seliba se tebileng. pompo ea turbine e otlolohileng tla cavitate. Cavitation e senya impeller ea pompo, 'me ho sisinyeha ho ka ama bophelo ba litiiso le libere.

9. Lebelo la Pompo

Lebelo leo pompo e sebetsang ka lona ke ntlha e 'ngoe ea bohlokoa. Mohlala, pompo e mathang ka lebelo la 3,550 rpm e tla roala ka makhetlo a mane ho isa ho a robeli ho feta e le 'ngoe e mathang ka 1,750 rpm.

10. Impeller Balance

Li-impellers tse sa leka-lekaneng lipompong tsa cantilever kapa meralo e itseng e emeng e ka etsa hore shaft e sisinyehe, boemo bo khelosang sefate, joalo ka matla a radial ha pompo e baleha BEP. Ho kheloha ha radial le shaft wobble ho ka etsahala ka nako e le 'ngoe.

11. Tokiso ea Liphaephe le Sekhahla sa Phallo ea Inlet

Ntho e 'ngoe ea bohlokoa eo ho nahanoang ka eona bakeng sa ho lelefatsa bophelo ba pompo ke hore na lipompo li hlophisoa joang, ke hore na mokelikeli o "kenngoa" joang ka har'a pompo. Ka mohlala, setsoe ka sefofaneng se otlolohileng ka lehlakoreng la pompong se tla ba le liphello tse fokolang ho feta setsoe se otlolohileng - ho beleha ha hydraulic ea impeller ho feta, ka hona, li-bearings li jarisoa ka mokhoa o ts'oanang.

12. Mocheso o sebetsang oa pompo

Thempereichara ea ts'ebetso ea pompo, ebang e chesa kapa e bata, haholo-holo sekhahla sa phetoho ea mocheso, e ka ba le tšusumetso e kholo bophelong le ho tšepahala ha pompo e tebileng ea turbine e otlolohileng hantle. Mocheso o sebetsang oa pompo o bohlokoa haholo 'me pompo e tlameha ho etsoa ho finyella mocheso o sebetsang. Empa habohlokoa le ho feta ke lebelo la ho fetoha ha mocheso.

13. Pump Casing Penetrations

Le hoja e sa nkoe hangata, lebaka la hore ho kenella ha pompo ea casing ke khetho ho e-na le maemo a tloaelehileng bakeng sa lipompo tsa ANSI ke hore palo ea ho kenella ha pompo ea casing e tla ba le phello e itseng bophelong ba pompo, kaha libaka tsena ke tsona libaka tse ka sehloohong tsa ho senya le. khatello ea maikutlo (e phahama). Basebelisi ba bangata ba ho qetela ba batla hore casing e chekoe ebe e tapiloe bakeng sa drain, exhaust, likou tsa lisebelisoa. Nako le nako ha sekoti se phunngoa 'me se kenngoa holim'a khetla, ho sala khatello ea maikutlo ka har'a thepa, e fetohang mohloli oa ho phunyeha ha khatello ea kelello le sebaka seo kutu e qalang ho sona.

Tse ka holimo ke tsa litšupiso tsa mosebelisi feela. Bakeng sa lipotso tse tobileng, ka kopo ikopanye le CREDO PUMP.
