Phantse zonke izinto eziya kubomi obuthembekileyo bompompo ukuya kumsebenzisi wokugqibela, ngakumbi indlela ipompo esebenza ngayo kwaye igcinwe ngayo. Ziziphi izinto ezinokulawulwa ngumsebenzisi wokugqibela ukwandisa ubomi bompompo? Le miba ilandelayo ili-13 eqaphelekayo yingqwalasela ebalulekileyo yokwandisa ubomi bempompo.

1. Imikhosi yeRadial

Iinkcukacha-manani zemizi-mveliso zibonisa ukuba oyena nobangela mkhulu wokungacwangciswanga kwexesha leempompo ze-centrifugal kukuzala kunye/okanye ukusilela kotywino koomatshini. Iibheringi kunye netywina "zii-canaries kumgodi wamalahle" - zizibonakaliso zokuqala zempompo yempilo kunye nesandulela sokungaphumeleli ngaphakathi kwenkqubo yokumpompa. Nabani na osebenze kumzi mveliso wempompo ngalo naliphi na ixesha elide mhlawumbi uyazi ukuba eyona ndlela yokuqala yokuqhuba kukusebenzisa impompo okanye kufutshane neNdawo yokuSebenza ngokuFanelekileyo (BEP). Kwi-BEP, impompo yenzelwe ukumelana namandla amancinci e-radial. Xa usebenza kude ne-BEP, umphumo we-force vector kuwo onke amandla e-radial kwi-angle ye-90 ° ukuya kwi-rotor kwaye uzama ukuphambuka nokugoba i-shaft yepompo. Amandla eradial ephezulu kunye nesiphumo sokuphambuka kweshafu ngumbulali wetywina ngoomatshini kunye nento enegalelo kubomi obufutshane bokuzala. Ukuba i-radial force inkulu ngokwaneleyo, inokubangela ukuba i-shaft ijike okanye igobe. Ukuba uyeka impompo kwaye ulinganise i-shaft runout, awuyi kufumana nto iphosakeleyo kuba le yimeko eguquguqukayo, kungekhona enye. Ishafti egobileyo ebaleka nge-3,600 rpm iya kuphambuka kabini kwi-revolution nganye, ngoko iyakugoba amaxesha angama-7,200 ngomzuzu. Oku kuphambuka komjikelo ophezulu kwenza kube nzima kubuso betywina ukugcina uqhagamshelwano kunye nokugcina i-fluid layer (ifilimu) efunekayo ukuze isitywina sisebenze ngokufanelekileyo.

2. Ungcoliseko lweLubricant

Kwiibhola zebhola, ngaphezu kwe-85% yokungaphumeleli kokuthwala kubangelwa ukungcola, okunokuba luthuli kunye nomcimbi wangaphandle okanye amanzi. Iinxalenye nje ezingama-250 kwisigidi ngasinye (ppm) zamanzi zinokunciphisa ubomi balo ngomlinganiselo kane. Ubomi bezithambiso bubalulekile.

3. Uxinzelelo lokufunxa

Ezinye izinto eziphambili ezichaphazela ubomi bokuzala ziquka uxinzelelo lokufunxa, ukulungelelaniswa komqhubi, kunye nomlinganiselo othile wombhobho. Kwi-ANSI B 73.1 yenqanaba elinye leempompo zenkqubo yokuxhoma okuthe tye, amandla e-axial awenziwa kwirotor abheke kwizibuko lokufunxa, ngoko ke ukuya kuthi ga kwinqanaba elithile kwaye ngaphakathi kwemida ethile, uxinzelelo lokufunxa impendulo luya kunciphisa amandla e-axial, ngaloo ndlela inciphisa imithwalo ethwele imithwalo. kunye nokwandisa ubomi beiimpompo zeinjini yeinjini ezithe nkqo.

4. Ulungelelwaniso lomqhubi

Ukungahambi kakuhle kwempompo kunye nomqhubi unokulayisha ngokugqithiseleyo i-radial bear. Ubomi bokuthwala i-radial bunxulumene ngokubonakalayo kwinqanaba lokungahambi kakuhle. Ngokomzekelo, ngokungahambi kakuhle (ukulungiswa kakubi) kwee-intshi ze-0.060 kuphela, umsebenzisi wokugqibela unokufumana iingxaki zokuthwala okanye ukudibanisa emva kweenyanga ezintathu ukuya ezintlanu zokusebenza. Nangona kunjalo, ukuba i-misalignment yi-intshi ye-0.001, ipompo efanayo inokusebenza ngaphezu kweenyanga ze-90.

5. Uxinzelelo lwePipe

Uxinzelelo lwemibhobho lubangelwa kukungahambi kakuhle kokufunxa kunye/okanye ukukhupha imibhobho ngeeflange zempompo. Nakuyilo lwempompo olomeleleyo, uxinzelelo lwemibhobho lunokudlulisa ngokulula olu xinzelelo lunokuba lukhulu kwiibheringi kunye nokuhambelana kwazo kwezindlu ezihambelanayo. Imikhosi (uxinzelelo) inokubangela ukuba i-bearing fit ibe ngaphandle kokujikeleza kunye / okanye ngaphandle kokulungelelaniswa nezinye iibheringi, okubangela ukuba i-centerlines ibe kwiindiza ezahlukeneyo.

6. Iipropati zolwelo

Iipropati zolwelo ezifana ne-pH, i-viscosity, kunye nobunzima obuthile zizinto ezibalulekileyo. Ukuba ulwelo luneasidi okanye luyadleka, ukuhamba-hamba kwiindawo ze-a impompo yeinjini yomoya enzulu kakuhle njengomzimba wempompo kunye ne-impeller kufuneka ikwazi ukumelana nomhlwa. Izinto eziqinileyo zolwelo kunye nobukhulu balo, ukumila, kunye nokugqabhuka kwayo zizinto zonke.

7. Ukusetyenziswa rhoqo

Ukuphindaphinda kokusetyenziswa yenye into ebalulekileyo: Iqala kangaphi impompo kwixesha elinikiweyo? Ndizibonele ngokwam iimpompo eziqala kwaye ziyeke rhoqo kwimizuzwana embalwa. Izinga lokugqoka kule mipompo liphezulu kakhulu kunokuba ipompo isebenza ngokuqhubekayo phantsi kweemeko ezifanayo. Kule meko, uyilo lwenkqubo kufuneka lutshintshwe.

8. I-Net Positive Suction Head Margin

Umda omkhulu phakathi kwe-Net Positive Suction Head Available (NPSHA, okanye NPSH) kunye ne-Net Positive Suction Head efunekayo (NPSHR, okanye iNPSH iFunekayo), mancinci amathuba okuba liqula elinzulu. impompo yeinjini ethe nkqo iya cavitate. I-Cavitation iyonakalisa i-pump impeller, kwaye ukunyakaza okubangelwayo kunokuchaphazela ubomi beempawu kunye neebheringi.

9. Isantya sempompo

Isantya apho impompo isebenza khona yenye into ebalulekileyo. Umzekelo, ipompo esebenza kwi-3,550 rpm iya kunxiba amaxesha amane ukuya kwesibhozo ngokukhawuleza kunomnye osebenza kwi-1,750 rpm.

10. I-Impeller Balance

Ii-impellers ezingalungelelananga kwiimpompo ze-cantilever okanye uyilo oluthile oluthe nkqo lunokubangela ukugoba kwe-shaft, imeko ephambukisa i-shaft, efana ne-radial forces xa impompo ibaleka kwi-BEP. Ukuphambuka kweradial kunye ne-shaft wobble kungenzeka ngaxeshanye.

11. ULungiselelo lweMibhobho kunye neNqanaba lokuNgena lokuNgena

Olunye uqwalaselo olubalulekileyo ekwandiseni ubomi bempompo yindlela olungiselelwa ngayo imibhobho, okt indlela ulwelo “lulayishwa” ngayo kwimpompo. Umzekelo, ingqiniba kwinqwelomoya ethe nkqo kwicala lokufunxa lempompo iya kuba neziphumo ezibi kakhulu kune-elbow ethe tyaba - ukulayishwa kwe-hydraulic ye-impeller kuninzi ngakumbi, kwaye ngenxa yoko iibheringi zilayishwa ngokulinganayo.

12. Ubushushu bokusebenza kwempompo

Ubushushu bokusebenza kwempompo, nokuba kushushu okanye kuyabanda, kwaye ngakumbi umyinge wokutshintsha kobushushu, kunokuba nempembelelo enkulu kubomi kunye nokuthembeka kwempompo yeinjini yomoya ethe nkqo enzulu. Ubushushu bokusebenza kompompo bubaluleke kakhulu kwaye impompo kufuneka ilungiselelwe ukuhlangabezana nobushushu bokusebenza. Kodwa okubaluleke ngakumbi lizinga lokutshintsha kobushushu.

13. Ukungena kweMpompo yeCasing

Nangona kungasoloko kuqwalaselwa, isizathu sokuba ukungena kwempompo yempompo kuyindlela yokukhetha kunomgangatho weempompo ze-ANSI kukuba inani lokungena kwempompo ye-casing liya kuba nefuthe elithile kubomi bempompo, njengoko ezi ndawo ziyizona ndawo ziphambili zokubola kunye i-gradients yoxinzelelo (iphakama). Abasebenzisi abaninzi bokugqibela bafuna ukuba i-casing yombiwe kwaye icofe ukuze ikhuphe, ikhuphe, izibuko zezixhobo. Ngalo lonke ixesha umngxuma ugrunjwa kwaye ucofe kwigobolondo, i-gradient yoxinzelelo ishiywe kwizinto eziphathekayo, eziba ngumthombo wokuqhekeka koxinzelelo kunye nendawo apho i-corrosion iqala khona.
