I-Hydrostatic
I-Hydrostatic igatsha le-fluid mechanics elihambisanayocernihlanganiswe noketshezi lapho iphumule. Njengoba kushiwo ngaphambili, akukho ukucindezeleka okungathi sína noma okushelelayo okukhona phakathi kwezinhlayiya zoketshezi ezimile.
Ngakho-ke ku-hydrostatic, wonke amandla asebenza ngokujwayelekile endaweni enomphetho futhi azimele ekuqineni. Ngenxa yalokho, imithetho yokulawula ilula kakhulu, futhi ukuhlaziywa kusekelwe ekusetshenzisweni okuqondile kwezimiso zomshini zamandla nomzuzu. Izixazululo zinembile futhi asikho isidingo sokusebenzisa izindlela zokuhlola.
Injini yedizili I-Vertical Turbine multistage centrifugal inline shaft water I-Drainage Pump Lolu hlobo lwe-vertical drainage pump lusetshenziswa kakhulu ekupompeni ngaphandle kokugqwala, izinga lokushisa lingaphansi kuka-60 °C, izinto eziqinile ezimisiwe (ngaphandle kwe-fiber, ama-grits) ngaphansi kuka-150 mg/L kokuqukethwe kwendle noma amanzi angcolile. I-VTP vertical drainage pump itholakala kuma-VTP type vertical water pumps, futhi ngokusekelwe ekukhuleni kanye nekhola, i-tube lubrication isetshenziswa ngamanzi. Ingabhema izinga lokushisa elingaphansi kuka-60 °C, ithumele ukuqukatha okusanhlamvu okuqinile okuthile (njenge-scrap iron kanye nesihlabathi esihle, amalahle, njll.) kwendle noma amanzi angcolile.
Ukuqina kokucindezela
Umfutho wokucindezela noma, kalula, umfutho ebusweni amandla okucindezela endaweni ngayinye. KuMfanekiso 4, amandla okucindezela aqonde phansi asebenza ngokuvundlile
I-lamina ilingana nobunzima be-prism yoketshezi oluqondile ngaphezu kwayo, kanye nokuqina kokucindezela endaweni ehlangana nolunye uketshezi. Ukuze kube nokulingana okuzinzile kumele kube nokucindezela okuqondile okuphezulu okuhambisanayo ngaphansi kwe-lamina. Uma kwenzeka uketshezi olungacindezeleki luthintana nomoya, ingcindezi yegeji p (kuma-pascals) inikezwa yi
lapho u-w eyisisindo esithile soketshezi kanti u-h uyikujula okungaphansi kobuso obukhululekile. Lokhu kokugcina kubizwa ngokuthi i-press-
Fig.4. Amandla okucindezela ku-lamina evundlile engaphansi kwamanzi
Ikhanda eliqinile futhi ngokuvamile lishiwo ngamamitha oketshezi. Uhlobo lwesibalo lubonisa ukuthi ingcindezi iyanda ngokuhambisana nokujula. Njengoba amandla adonsela phansi kuyisici esibonakalayo esihilelekile, ubuso obukhululekile boketshezi olunganyakazi buhlala buvundlile futhi amandla okucindezela ayafana kunoma iyiphi indawo evundlile emzimbeni woketshezi. Ngaphezu kwalokho, kungabonakala ukuthi amandla okucindezela kunoma iyiphi inhlayiya ye-elemental afana kuzo zonke izinhlangothi. Lokhu kulandela ekucabangeni kwamandla okucindezela asebenza ku-prism eyisikwele engunxantathu (Umfanekiso 5) wobude obuvundlile beyunithi, enobukhulu besigaba δ.l,δx,δy, kanye nesisindo δw.
Umfanekiso 5. Ingcindezi yeces ku-prism engaphansi komhlaba enomumo ongunxantathu
Ukuze kube nokulingana ohlangothini oluvundlile,
Ngokufanayo ohlangothini oluqondile,
ukunganaki imigomo ye-oda lesibili enamanani amancane kakhulu,
Ngakho-ke umfutho wokucindezela awuncikile ekhoneni lokuthambekela kobuso be-elemental futhi uyafana kuzo zonke izinkomba.
Ukulinganisa ingcindezi
Tizinhlobo zedivayisi
Uma kwenzeka uketshezi olunobuso obukhululekile, i-pressUketshezi olukhona kunoma iyiphi indawo lumelelwa ukujula okungaphansi kobuso. Uma uketshezi luvalekile ngokuphelele, njengasemapayipini nasezindleleni zokucindezela, ingcindezi ayikwazi ukutholwa kalula futhi kudingeka idivayisi yokulinganisa efanele. Kunezinhlobo ezintathu eziyinhloko: (a) i-piezometer, (b) i-manometer, kanye (c) i-Bourdon gauge. Lezi ziboniswe zifakwe epayipini kuMfanekiso 6.
Iphampu yokubeka umthombo womoya ohlanzekile
Inombolo Yemodeli: TWP
Amaphampu Amanzi e-Wellpoint Water Pumps azimele ochungechungeni lwe-TWP aklanyelwe ngokubambisana yi-DRAKOS PUMP yaseSingapore kanye nenkampani i-REEOFLO yaseJalimane. Lolu chungechunge lwephampu lungathutha zonke izinhlobo zezinhlayiya ezihlanzekile, ezingathathi hlangothi nezingcolisayo. Xazulula amaphutha amaningi ephampu yokuzibopha yendabuko. Lolu hlobo lwephampu yokuzibopha oluhlukile olusebenza ngokuwomile luzoba ukuqala ngokuzenzakalelayo futhi luqale kabusha ngaphandle koketshezi ekuqaleni kokuqala, Ikhanda lokumunca lingaba ngaphezu kwamamitha angu-9; Umklamo omuhle kakhulu we-hydraulic kanye nesakhiwo esiyingqayizivele kugcina ukusebenza kahle okuphezulu kungaphezu kwama-75%. Futhi ukufakwa kwesakhiwo okuhlukile kokuzikhethela.
I-Piezometer
IUkuthepha kwe-fa kwenziwa ebusweni bomngcele futhi ithubhu ende ngokwanele ixhunyiwe, uketshezi luzokhuphuka ethubhuni kuze kube yilapho lulinganiswa yingcindezi yomoya. Ingcindezi emzimbeni oyinhloko woketshezi imelelwa ukuphakama okuqondile kwekholomu yoketshezi. Ngokusobala, idivayisi ifanele kuphela ukucindezela okulinganiselwe, ngaphandle kwalokho uketshezi luzokhuphuka kakhulu ethubhu ye-piezometer ukuze kulinganiswe kalula.
Umfanekiso 6. Amadivayisi okulinganisa ingcindezi
Uma uketshezi lugeleza, ukuthepha kwe-piezometer akufanele kudlule ububanzi obungu-3 mm futhi kufanele kuhlanzeke ebusweni bomngcele. Ukuze kube nokunemba okukhulu, kungafakwa indandatho ye-piezometer. Lokhu kuqukethe igumbi elizungezile elizungeze ipayipi futhi lixhunywe kulo ngokucindezela okuningana okulinganayo.
I-Manometer
I-Manometer Isimiso siyafana naleso esichazwe ngenhla, kodwa ubunzima obuhambisana nethubhu elide kakhulu bunqotshwa ngokufaka ithubhu le-U eliqukethe uketshezi olungaxubeki. I-Mercury (ubukhulu obuthile obungu-13,6) uketshezi lwe-manometer oluvame ukusetshenziswa ekulinganiseni umfutho wamanzi. Ingcindezi yegeji p epayipini inikezwa yi
Kuphi
h= umehluko ezingeni loketshezi lwe-manometer emalungeni amabili,
z= ukuphakama komugqa ophakathi wepayipi ngaphezu kwe-meniscus esithweni ohlangothini lwepayipi, kanye
w, wm = isisindo esithile soketshezi lwepayipi kanye ne-manometer ngokulandelana.
Uma sibheka izikhundla ezishintshashintshayo ze-menisci, ukulinganisa okuqondile akunakwenzeka. Kodwa-ke, lokhu kungafezwa uma umlenze ohlangothini lwepayipi ukhuliswa kakhulu ukuze izinga le-meniscus lihlale lifana. Ukucindezela kungafundwa esikalini esihlanganisiwe nesinye isitho.
Fig.7. I-manometer ehlukile
Ukuhlolwa kobuningi bokugeleza kwamapayipi kuvame ukusekelwe ekulinganisweni komehluko wokucindezela phakathi kokuthepha okuseduze. Kusetshenziswa i-differential manometer (Isithombe 7) kanti uketshezi lwe-manometer luvame ukuba yi-mercury. Uma umehluko wokucindezela umncane, uketshezi olulula olungaxubeki luzoletha imiphumela enembe kakhudlwana.
Umehluko wokucindezela we-pt- pzis onikezwe yi-
lapho izimpawu zinencazelo efanayo nesesilinganisweni 6. Uma ipayipi livundlileal,
Ama-manometer ahlukene ayinkimbinkimbi kakhulu aklanywe ukuze ahlangabezane nezidingo ezithile zomsebenzi wezentengiselwano nowelebhu.
Bi-ourdon gauge
Leli ithuluzi lokuhweba elifakwe ngqo epayipini uqobo noma ekugcineni komugqa we-piezometer. Lakhiwe ngepayipi eligobile elilengiswe ngokukhululeka engxenyeni egobile futhi libanjwe ngokuqinile esiqwini. Ukwanda kwengcindezi yangaphakathi kuvame ukuqondisa ipayipi futhi, njengoba ukuphambuka kuhambisana ngqo nengcindezi esetshenzisiwe, indlela elula yenza ukuthi lokhu kwamuva kuqoshwe ngqo. Njengoba ingcindezi engaphandle kwepayipi ingaphakathi, ingcindezi yegeyiji ibhalisiwe futhi lokhu kuvame ukusebenza endaweni ephakathi yethuluzi.
I-Bourdon gauge iwusizo njengesibonakaliso esijwayelekile sokucindezela kodwa ayifaneleki lapho kudingeka khona ukunemba okukhulu, njengoba kunjalo ngokuvamile lapho kufanele kulinganiswe ukucindezela okuhlukile.
Iphampu Yomlilo Eqondile Ye-Turbine
Inombolo Yemodeli: XBC-VTP
Amaphampu okulwa nomlilo aqondile e-XBC-VTP Series ayizinhla zamaphampu okusabalalisa umlilo esiteji esisodwa, anezitezi eziningi, akhiqizwa ngokuhambisana ne-National Standard GB6245-2006 yakamuva. Siphinde sathuthukisa umklamo ngokubhekisela kwendinganiso ye-United States Fire Protection Association. Isetshenziswa kakhulu ekuhlinzekeni ngamanzi omlilo kumakhemikhali kaphethiloli, igesi yemvelo, isitshalo sikagesi, indwangu kakotini, ichweba, izindiza, izindawo zokugcina impahla, izakhiwo eziphakeme kanye nezinye izimboni. Ingasebenza nasemikhumbini, ethangini lolwandle, emikhumbini yomlilo nakwezinye izenzakalo zokuhlinzeka.
Iphampu Yokuya Emanzini Olwandle Oluphakathi
Inombolo Yemodeli: I-ASN ASNV
Amaphampu e-ASN kanye ne-ASNV ayizimpompi ze-centrifugal ezisetshenziswa njenge-single-stage double suction split volute casing kanye nokuthuthwa okusetshenzisiwe noma okuwuketshezi kwemisebenzi yamanzi, ukujikeleza komoya opholile, isakhiwo, ukuchelela, isiteshi sokumpompa amanzi, isiteshi sikagesi, uhlelo lokuphakelwa kwamanzi ezimbonini, uhlelo lokulwa nomlilo, imikhumbi, isakhiwo nokunye.
