I-Hydrostatic
IHydrostatic igatsha le-fluid mechanics okuyi-concerned noketshezi lapho uphumule.Njengoba kushiwo ngaphambili, akukho ukucindezelwa kwe-tangential noma kwe-shear okukhona phakathi kwezinhlayiya ezimile zoketshezi.
Ngakho ku-hydrostatic, wonke amandla asebenza ngokujwayelekile endaweni yomngcele futhi azimele ku-viscosity.Ngenxa yalokho, imithetho elawulayo ilula, futhi ukuhlaziya kusekelwe ekusetshenzisweni okuqondile kwezimiso zemishini zamandla kanye nomzuzu.Izixazululo zinembile futhi asikho isidingo sokuzama ukuzama.
Injini kadizili i-Vertical Turbine multistage centrifugal inline shaft water Pump Iphampu yokudonsa Lolu hlobo lwepompo lokudonsa amanzi oluma mpo lusetshenziselwa ikakhulukazi ukumpompa okungagqwali, izinga lokushisa elingaphansi kuka-60 °C, okuqinile okumisiwe (okungafaki i-fiber, amagrits) ngaphansi kuka-150 mg/L okuqukethwe indle noma amanzi angcolile.Iphampu yamanzi yohlobo lwe-VTP eqondile ikuhlobo lwe-VTP lwamaphampu amanzi aqondile, futhi ngesisekelo sokwanda kanye nokhololo, setha ukugcotshwa kukawoyela weshubhu kungamanzi.Ingabhema izinga lokushisa elingaphansi kuka-60 °C, ithumele ukuqukatha okusanhlamvu okuqinile okuthile (okufana nensimbi eyizilahlwa nesihlabathi esicolekileyo, amalahle, njll.) yendle noma amanzi alahlwayo.
Amandla okucindezela
Amandla okucindezela noma, kalula nje, ingcindezi engaphezulu ingamandla okucindezela endaweni ngayinye yeyunithi.Emfanekisweni wesi-4, amandla okucindezela abheke phansi ame mpo asebenza ngokuvundlile
I-lamina ilingana nesisindo se-prism yoketshezi ngokuma mpo ngaphezu kwayo, kanye namandla okucindezela kusixhumi esibonakalayo nolunye uketshezi.Ukuze kube nokulingana okumile kufanele kube nokucindezela okuqondile okukhuphukayo okuhambisanayo ngezansi kwe-lamina.Endabeni yoketshezi olungenakucindezelwa lapho luthintana nomoya, umfutho wegeji u-p (kuma-pascals) unikezwa
lapho u-w eyisisindo esithile soketshezi kanye no-h ukujula ngaphansi kwendawo ekhululekile.Lesi sakamuva sibizwa ngokuthi i-Pres-
Fig.4.Ingcindezi iphoqa ku-lamina evundlile engaphansi kwamanzi
ikhanda eliqinisekile futhi ngokuvamile lishiwo ngamamitha oketshezi.Ifomu le-equation libonisa ukuthi ingcindezi ikhuphuka ngokulandelana ngokujula.Njengoba amandla adonsela phansi eyinto ebonakalayo ehilelekile, indawo ekhululekile yoketshezi olumile ihlala ivundlile futhi amandla okucindezela ayafana kunoma iyiphi indiza evundlile ngaphakathi komzimba woketshezi.Ngaphezu kwalokho, kungase kuboniswe ukuthi amandla okucindezela kunoma iyiphi izinhlayiya eziyisisekelo ayafana kuzo zonke izinhlangothi.Lokhu kulandela ukucatshangelwa kwamandla okucindezela asebenza kuprism eyisisekelo emise okukanxantathu(Fig.5) yeyunithi yobude obuvundlile, enobukhulu besigaba δl,δx,δy, nesisindo δw.
Fig.5.Ingcindezi yeces on the prism engaphansi emise okukanxantathu
Ukuze uthole ukulinganisa endaweni evundlile,
Ngokufanayo ekuqondeni mpo,
ukunganaki imigomo ye-oda lesibili lamanani amancane kakhulu,
Ngakho-ke Ukuqina kokucindezela kuzimele ku-engeli yokuthambekela kwendawo eyisisekelo futhi kuyafana kuzo zonke izinkomba.
Isilinganiso sokucindezela
Tizinhlobo zedivayisi
Endabeni yoketshezi olunendawo yamahhala, i-pressi-ure kunoma iyiphi indawo imelelwa ukujula okungaphansi komhlaba.Lapho uketshezi luvaleke ngokuphelele, njengamapayipi namapayipi okucindezela, ukucindezela akukwazi ukutholakala kalula futhi idivayisi yokulinganisa efanelekile iyadingeka.Kunezinhlobo ezintathu eziyinhloko:(a) i-piezometer,(b) i-manometer, kanye (c) ne-Bourdon gauge.Lezi ziboniswa zifakwe epayipini kuMfanekiso 6.
Vacuum iphampu yephuzu lomthombo
Inombolo Model: TWP
Uchungechunge lwe-TWP Injini ye-Movable Diesel Engine ezenzelayo Iphuzu Lamanzi Amaphampu ezimo eziphuthumayo ahlanganiswe aklanywa i-DRAKOS PUMP yaseSingapore kanye nenkampani ye-REEOFLO yaseJalimane.Lolu chungechunge lwephampu lungathwala zonke izinhlobo zezinto ezihlanzekile, ezingathathi hlangothi kanye nezibolayo eziqukethe izinhlayiya.Xazulula amaphutha amaningi ephampu azilungisayo.Lolu hlobo lwe-self-priming futha isakhiwo esiyingqayizivele sokugijima esomile sizoqalisa futhi siqalise kabusha ngaphandle koketshezi ekuqaleni kokuqala, Ikhanda lokumunca lingaba ngaphezu kuka-9 m;Umklamo omuhle kakhulu we-hydraulic kanye nesakhiwo esiyingqayizivele sigcina ukusebenza kahle okuphezulu ngaphezu kwama-75%.Nokufakwa kwesakhiwo okuhlukile kokuzikhethela.
I-Piezometer
IUkuthepha kwe-fa kwenziwa endaweni yomngcele kanye neshubhu elide ngokwanele elixhunyiwe, uketshezi luzokhuphuka ku-tube kuze kube yilapho kulinganisa ukucindezela komkhathi.Ingcindezi emzimbeni oyinhloko woketshezi imelelwa ukuphakama okuqondile kwekholomu yoketshezi.Ngokusobala, idivayisi ifaneleka kuphela ukucindezela okulinganiselwe, ngaphandle kwalokho uketshezi luzokhuphuka kakhulu ku-piezometer tube ukuze kulinganiswe kalula.
Fig.6.Amadivayisi okulinganisa ukucindezela
Lapho uketshezi lugeleza, ukuthepha kwe-piezometer akufanele kudlule ububanzi obuyi-3 mm futhi kufanele kushaywe nge-surface yomngcele.Ukuze uthole ukunemba okukhulu, indandatho ye-piezometer ingase ifakwe.Lokhu kuhlanganisa igumbi elihlala njalo ngonyaka elizungeze ipayipi futhi lixhunywe kulo ngokuthinta okumbalwa okulinganayo.
I-Manometer
I-Manometer Isimiso siyefana nalesi esichazwe ngenhla, kodwa ubunzima obuhambisana neshubhu elide ngokwedlulele bunqotshwa ngokufaka i-U-tube equkethe uketshezi olungenakulinganiswa.I-Mercury(i-gravity ethize 13,6) iwuketshezi lwe-manometer ngokuvamile olusetshenziselwa ukukala umfutho wamanzi.I-gauge pressure p ephayiphini inikezwa ngu
Kuphi
h = umehluko ezingeni le-manometer liquid emilenzeni emibili,
z=ubude bomugqa omaphakathi wepayipi ngaphezu kwe-meniscus esithweni ohlangothini lwepayipi, futhi
w, wm = ubukhulu obuthile bepayipi kanye noketshezi lwe-manometer ngokulandelanayo.
Uphiko oluya ezikhundleni eziguquguqukayo ze-menisci, ukulinganisa okuqondile akunakwenzeka.Kodwa-ke, lokhu kungase kufinyelelwe uma isitho esohlangothini lwepayipi sikhuliswa kakhulu ukuze izinga le-meniscus lihlale lifana.Izingcindezi zingabe sezifundwa esikalini esineziqu esixhunywe kwesinye isitho.
Fig.7.I-manometer ehlukile
Ukuhlolwa kobuningi bokugeleza kwepayipi ngokuvamile kusekelwe esilinganisweni somehluko wengcindezi phakathi kokuthepha okuseduze.I-manometer ehlukile (Fig.7) isetshenziswa futhi i-manometer liquid ngokuvamile i-mercury.Uma umehluko wengcindezi umncane, uketshezi olulula olungenakulinganiswa luzoveza imiphumela enembe kakhudlwana.
Umehluko we-pressure pt- pzis onikezwe ngu
lapho izimpawu zinencazelo efanayo ne-Equation 6. Uma ipayipi livundlileal,
Kuye kwaklanywa ama-manometer ahlukene emvelo eyinkimbinkimbi ukuze ahlangabezane nezidingo ezithile zebhizinisi nelabhorethri.
Byethudon gauge
Leli ithuluzi lokuthengisa elifakwe ngqo epayipini ngokwalo noma ekugcineni komugqa we-piezometer.Iqukethe ishubhu eligobile elilengiswe ngokukhululekile engxenyeni egobile futhi libanjwe ngokuqinile esiqwini.Ukwanda kokucindezela kwangaphakathi kuvame ukuqondisa ithubhu futhi, njengoba ukuphambuka kuhambisana ngokuqondile nokucindezela okusetshenzisiwe, indlela elula yenza lokhu okulandelayo kuqoshwe ngokuqondile.Njengoba ingcindezi engaphandle kweshubhu isendaweni yasemkhathini, ingcindezi yegeji ibhalisiwe futhi lokhu kuvame ukusebenza endaweni emaphakathi yethuluzi.
I-gauge ye-Bourdon iwusizo njengenkomba evamile yokucindezela kodwa ayifaneleki lapho kudingeka khona ukunemba okukhulu, njengoba kuvame ukuba njalo lapho izingcindezi ezihlukene zizokalwa.
Iphampu yomlilo ye-Turbine emile
Inombolo Model:XBC-VTP
I-XBC-VTP Series amaphampu okucisha umlilo amile kushaft eside awuchungechunge lwesiteji esisodwa, amaphampu okukhipha amanzi esiteji amaningi, akhiwe ngokuvumelana ne-National Standard GB6245-2006 yakamuva.Siphinde sathuthukisa idizayini ngereferensi yezinga le-United States Fire Protection Association.Isetshenziselwa ikakhulukazi ukuhlinzekwa kwamanzi omlilo ku-petrochemical, igesi yemvelo, imboni yamandla, indwangu kakotini, i-wharf, izindiza, indawo yokugcina impahla, izakhiwo eziphakeme nezinye izimboni.Ingasebenza futhi emkhunjini, ithangi lasolwandle, umkhumbi wezicishamlilo nezinye izikhathi zokuhlinzeka.
I-Centrifugal Sea Water Destination Pump
Inombolo Model:ASN ASNV
Amaphampu emodeli ye-ASN kanye ne-ASNV angamaphampu esiteji esisodwa esiphindwe kabili ahlukanisa i-volute casing casing centrifugal futhi asetshenzisiwe noma ezokuthutha eziwuketshezi ukuze asebenze amanzi, ukujikeleza kwe-air-conditioning, isakhiwo, ukuchelela, isiteshi sokumpompa amanzi, isiteshi samandla kagesi, uhlelo lokuhlinzeka ngamanzi ezimbonini, ukulwa nomlilo. uhlelo, umkhumbi, isakhiwo nokunye.
