- I-Slurry Pump: Kuyini, futhi kusebenza kanjaniAmaphampu adizayinelwe ukumpompa ama-slurries azoba umsebenzi osindayo kunalawo aklanyelwe uketshezi olunamehlo amancane njengoba ama-slurries enzima futhi kunzima ukuwapompa.Amaphampu we-Slurry ngokuvamile zinkulu ngosayizi kunamaphampu avamile, anamandla ehhashi engeziwe, futhi zakhiwe ngamabherengi namashafti aqinile. Uhlobo oluvame kakhulu lwepompo le-slurry yiphampu ye-centrifugal. Lawa maphampu asebenzisa i-impeller ezungezayo ukuze anyakazise i-slurry, ngendlela efanayo nendlela uketshezi olufana namanzi oluzohamba ngayo kupompo evamile eyi-centrifugal.
Amaphampu e-Centrifugal alungiselelwe ukumpompa ngodaka ngokuvamile azofaka okulandelayo uma kuqhathaniswa namaphampu amaphakathi amaphakathi:
• Ama-impeller amakhulu enziwe ngezinto eziningi. Lokhu okokunxephezela ukuguga okubangelwa ama-slurries abrasive.
Lezi zimo zihlanganisa:
• Izinga lokugeleza kwe-slurry eliphansi
• Ikhanda eliphakeme (okungukuthi, ubude lapho iphampu ingahambisa khona uketshezi)
• Isifiso sokusebenza kahle kakhulu kunaleso esinikezwa amaphampu amaphakathi
• Ukulawulwa kokugeleza okuthuthukisiwe
Izinhlobo ezijwayelekile zamaphampu ahambayo asetshenziswa ezinhlelweni zokupompa i-slurry zifaka:
Lawa maphampu asebenzisa ama-meshing lobe amabili azungeza ngaphakathi kwendlu yephampu ukuze asuse uketshezi olusuka endaweni yokungena yephampu luyise endaweni yalo.
Amaphampu angama-twin-screw
Lawa maphampu asebenzisa izikulufu ezizungezisayo ukuhambisa uketshezi nezinto eziqinile ukusuka komunye umkhawulo wepompo ukuya komunye. Isenzo sokujika sezikulufu sidala ukunyakaza okuphotha okupompa okubalulekile.
Lawa maphampu asebenzisa ulwelwesi olunwebekayo olunweba ivolumu yegumbi lokumpompa, oluletha uketshezi oluvela ku-valve yokungena bese lulukhipha nge-valve yokuphuma.
Ukukhetha nokusebenza aiphampu ye-slurry
Ukukhetha iphampu elungile yohlelo lwakho oludaka kungaba umsebenzi oyinkimbinkimbi ngenxa yebhalansi yezinto eziningi ezihlanganisa ukugeleza, ingcindezi, i-viscosity, ukuhuga, usayizi wezinhlayiyana, nohlobo lwezinhlayiyana. Unjiniyela wezinhlelo zokusebenza, owazi ukuthi angazicabangela kanjani zonke lezi zici, angaba usizo olukhulu ekuzuleni izinketho eziningi zamaphampu ezitholakalayo.
Ekunqumeni ukuthi yiluphi uhlobo lweiphampu ye-slurrylufaneleka kakhulu uhlelo lwakho lokusebenza, landela lezi zinyathelo ezine ezilula.
Umhlahlandlela Wabasaqalayo Wokupompa Udaka
I-slurry ingenye yoketshezi oluyinselele kakhulu ukunyakaza. Iyaluma kakhulu, iwugqinsi, kwesinye isikhathi iyagqwala, futhi iqukethe ukugcwala okuphezulu kwezinto eziqinile. Akungabazeki ukuthi, udaka luqinile kumaphampu. Kodwa ukukhetha iphampu efanele yalezi zinhlelo zokusebenza ezilimazayo kungenza umehluko ekusebenzeni kwesikhathi eside.
IYINI “I-SLURRY”?
I-slurry yinoma iyiphi ingxube yoketshezi kanye nezinhlayiya eziqinile eziqinile. Izibonelo zama-slurries zingabandakanya: umquba, usimende, isitashi, noma amalahle alenga emanzini. Ama-slurries asetshenziswa njengendlela elula yokuphatha izinto eziqinile ezimayini, ukucubungula insimbi, izisekelo, ukukhiqiza ugesi, futhi kamuva nje, imboni yezimayini ye-Frac Sand.
Ama-slurries ngokuvamile aziphatha ngendlela efanayo noketshezi oluwugqinsi, lwe-viscous, olugeleza ngaphansi kwamandla adonsela phansi, kodwa futhi luyampontshwa njengoba kudingeka. Ama-slurries ahlukaniswe abe izigaba ezimbili ezijwayelekile: ukungalungisi noma ukuhlalisa.
Ama-slurries angahlali ahlanganisa izinhlayiya ezinhle kakhulu, ezinikeza inkohliso yokwanda kwe-viscosity ebonakalayo. Lawa ma-slurry ngokuvamile anezakhiwo ezigqoke kancane, kodwa adinga ukucatshangelwa ngokucophelela lapho kukhethwa iphampu elungile ngoba awaziphathi ngendlela efanayo noketshezi oluvamile.
Ukumisa ama-slurries akhiwa yizinhlayiya eziqinile ezivame ukwakha ingxube engazinzile. Ukunakwa okukhethekile kufanele kunikezwe izibalo zokugeleza namandla lapho kukhethwa iphampu. Iningi lezicelo ze-slurry zenziwe ngezinhlayiya ezimahhadla futhi ngenxa yalokhu, zinezakhiwo zokugqoka eziphakeme.
Ngezansi izici ezivamile zama-slurries:
• Abrasive
• Ukungaguquguquki okukhulu
• Ingaqukatha inani eliphezulu lokuqinile
• Ngokuvamile lungisa ngokushesha
• Idinga amandla amaningi ukuze isebenze kunepompo “yamanzi”
Izinhlobo eziningi zamaphampu zisetshenziselwa ukudonsa ama-slurries, kodwa avame kakhuluiphampu ye-slurryiphampu ye-centrifugal. I-centrifugaliphampu ye-slurryisebenzisa amandla aphakathi nendawo akhiqizwe i-impeller ezungezayo ukuze ithinte amandla e-kinetic ku-slurry, ngendlela efanayo nendlela uketshezi olufana namanzi oluzohamba ngayo kwiphampu ye-centrifugal evamile.
Izicelo ze-slurry zinciphisa kakhulu impilo yokugqoka elindelekile yezingxenye zokupompa. Kubalulekile ukuthi amaphampu adizayinelwe lezi zinhlelo zokusebenza ezisindayo akhethwe kusukela ekuqaleni. Cabangela lokhu okulandelayo lapho ukhetha:
IZIQINISEKISO zamaphampu
Ukuqinisekisa ukuthi iphampu izobhekana nokuguga, usayizi/idizayini ye-impeller, into yokwakha, nokulungiselelwa kokukhipha amanzi kufanele kukhethwe kahle.
Ama-impeller avulekile yiwona avame kakhulu kumaphampu anodaka ngoba mancane amathuba okuthi avale. Ngakolunye uhlangothi ama-impeller avaliwe yiwona okungenzeka kakhulu ukuthi avimbe futhi anzima kakhulu ukuwahlanza uma evala.
Ama-slurry impellers amakhulu futhi aminyene. Lokhu kuzisiza ukuthi zisebenze isikhathi eside ezixubeni ezinodaka oluqinile.
Amaphampu athambilengokuvamile amakhulu ngosayizi uma eqhathaniswa namaphampu oketshezi ane-viscosity ephansi futhi ngokuvamile adinga amandla ehhashi amaningi ukuze asebenze ngoba awasebenzi kahle. Ama-bearings kanye nama-shafts kufanele abe magobolondo futhi aqine futhi.
Ukuvikela isikhwama sephampu ekuhutsheni,amaphampu aludakazivame ukulayishwa ngensimbi noma irabha.
Ama-casings ensimbi akhiwe ngama-alloys aqinile. Lawa ma-casings akhelwe ukumelana nokuguguleka okubangelwa ukwanda kwengcindezi nokujikeleza kwegazi.
Ama-casings akhethiwe ukuze ahambisane nezidingo zohlelo lokusebenza. Ngokwesibonelo, amaphampu asetshenziswa ekukhiqizeni usimende aphatha izinhlayiya ezinhle lapho kunengcindezi ephansi. Ngakho-ke, i-casing yokwakha elula iyamukeleka. Uma iphampu ibamba amatshe, isikhwama sepompo kanye ne-impeller izodinga i-casing ewugqinsi futhi enamandla.
IZINCABANGO ZOKUPHONSA OKUHLELI
Labo abanolwazi lokupompa ama-slurries bayazi ukuthi akuwona umsebenzi olula. Ama-slurries ayasinda futhi kunzima ukuwapompa. Zibangela ukuguga ngokweqile kumaphampu, izingxenye zawo, futhi zaziwa ngokuvala imigqa yokumunca nokukhipha uma zinganyakazi ngokushesha ngokwanele.
Kuyinselele ukwenzaamaphampu aludakahlala isikhathi esikahle. Kodwa, kunezinto ezimbalwa ongazenza ukuze welule impilo yakhoiphampu ye-slurryfuthi wenze ukupompa udaka kungabi yinselele.
• Thola indawo yobumnandi evumela ukuthi iphampu ihambe kancane ngangokunokwenzeka (ukunciphisa ukuguga), kodwa isheshe ngokwanele ukuze kuvinjwe izinto eziqinile zingami futhi zivale imigqa.
• Ukuze unciphise ukuguga, yehlisa ingcindezi yokukhipha iphampu iye endaweni ephansi kakhulu ngangokunokwenzeka
• Landela izimiso zamapayipi ezifanele ukuze uqinisekise ukulethwa okungaguquki nokufana kwe-slurry epompo
Ukupompa ama-slurries kubangela izinselele nezinkinga ezimbalwa, kodwa ngokukhetha okufanele kobunjiniyela nemishini, ungathola iminyaka eminingi yokusebenza ngaphandle kokukhathazeka. Kubalulekile ukusebenzisana nonjiniyela oqeqeshiwe lapho ukhetha iphampu enodaka ngoba ama-slurries angadala umonakalo epompo uma ingakhethwanga kahle.
