I-Hydrostatic
I-Hydrostatic lisebe le-fluid mechanics elijongenecernixutywe nolwelo xa iphumle. Njengoko bekutshiwo ngaphambili, akukho xinzelelo lwe-tangential okanye lwe-shear olukhoyo phakathi kwamasuntswana olwelo angashukumiyo.
Ngoko ke kwi-hydrostatic, onke amandla asebenza ngokuqhelekileyo kumphezulu womda kwaye azimele kwi-viscosity. Ngenxa yoko, imithetho yokulawula ilula kakhulu, kwaye uhlalutyo lusekelwe ekusetyenzisweni okulula kwemigaqo yoomatshini yamandla kunye nomzuzu. Izisombululo zichanekile kwaye akukho mfuneko yokuba kusetyenziswe uvavanyo.
Injini yedizili I-Vertical Turbine multistage centrifugal inline shaft water I-Drainage Pump Olu hlobo lwe-vertical drainage pump lusetyenziswa kakhulu ekupompeni ngaphandle kokubola, ubushushu bungaphantsi kwama-60 °C, izinto eziqinileyo ezixhonyiweyo (ngaphandle kwefayibha, iigrits) ngaphantsi kwe-150 mg/L yomxholo we-lindle okanye amanzi amdaka. I-VTP type vertical drainage pump ikwi-VTP type vertical water pumps, kwaye ngokusekelwe ekunyukeni kunye nekhola, i-tube lubrication ibekwe ngamanzi. Ingatshaya ubushushu obungaphantsi kwama-60 °C, ithumele ukuba iqulathe ingqolowa ethile eqinileyo (njenge-crap iron kunye nesanti entle, amalahle, njl.njl.) ye-lindle okanye amanzi amdaka.
Uxinzelelo oluphezulu
Uxinzelelo okanye, ngokulula, uxinzelelo olukumphezulu ngamandla oxinzelelo ngokwendawo nganye. KuMfanekiso 4, amandla oxinzelelo olusezantsi oluthe nkqo asebenza ngokuthe tye
I-lamina ilingana nobunzima beprism yolwelo ngokuthe nkqo ngaphezulu kwayo, kunye noxinzelelo oluphezulu kwindawo edibana nolunye ulwelo. Ukuze kubekho ukulingana okungaguqukiyo kufuneka kubekho uxinzelelo oluhambelanayo oluphezulu oluthe nkqo ngaphantsi kwe-lamina. Kwimeko yolwelo olungacinezelekiyo oludibana nomoya, uxinzelelo lwe-gauge p (kwii-pascals) lunikwa yi
apho u-w bubunzima obuthile bolwelo kwaye u-h bubunzulu obungaphantsi komphezulu okhululekileyo. Lo wokugqibela ubizwa ngokuba yi-press-
Fig.4. Amandla oxinzelelo kwi-lamina ethe tyaba engaphantsi kwamanzi
Intloko eqinisekileyo kwaye ngokubanzi ichazwa kwiimitha zolwelo. Uhlobo lwe-equation lubonisa ukuba uxinzelelo luyanda ngokulandelelana ngobunzulu. Njengoko umxhuzulane uyimpawu ebonakalayo ebandakanyekayo, umphezulu okhululekileyo wolwelo oluzinzileyo uhlala uthe tyaba kwaye uxinzelelo lufana nakweyiphi na indawo ethe tyaba ngaphakathi komzimba wolwelo. Ngaphezu koko, kunokuboniswa ukuba uxinzelelo oluphezulu kuyo nayiphi na isuntswana eliphambili lufana kuzo zonke iindlela. Oku kulandela ekuqwalaselweni kwamandla oxinzelelo asebenza kwiprism emile okwesithabatho esinxantathu (Umzobo 5) yobude obuthe tyaba beyunithi, enobukhulu becandelo δ.l,δx,δy, kunye nobunzima δw.
Umfanekiso 5. Uxinzelelo lweces kwiprism engaphantsi komhlaba enemilo engunxantathu
Ukuze kubekho ulungelelwano kwicala elithe tye,
Ngokufanayo kwicala elithe nkqo,
ukungahoyi imiqathango yesibini yomlinganiselo omncinci kakhulu,
Ngoko ke, ubunzulu boxinzelelo abuxhomekekanga kwi-engile yokuthambekela komphezulu we-elemental kwaye buyafana kuzo zonke iindlela.
Umlinganiselo woxinzelelo
Tiintlobo zesixhobo
Kwimeko yolwelo olunomphezulu okhululekileyo, i-pressUbungakanani kuyo nayiphi na indawo bumelwa bubunzulu obungaphantsi komphezulu. Xa ulwelo luvalekile ngokupheleleyo, njengakwimibhobho nakwiindlela zoxinzelelo, uxinzelelo alunakuqondwa lula kwaye kufuneka isixhobo sokulinganisa esifanelekileyo. Kukho iintlobo ezintathu eziphambili: (a) i-piezometer, (b) i-manometer, kunye (c) i-Bourdon gauge. Ezi ziboniswe zifakwe kumbhobho kuMfanekiso 6.
Impompo yokuprima amanzi equla
Inombolo yoMzekelo: TWP
Iimpompo zamanzi ze-TWP ezizitshixayo zenjini yedizili ezizitshixayo ze-Wellpoint zenzelwe ungxamiseko yi-DRAKOS PUMP yaseSingapore kunye nenkampani ye-REEOFLO yaseJamani. Olu luhlu lwempompo lunokuthutha zonke iintlobo zezixhobo ezicocekileyo, ezingathathi cala nezirhabaxa eziqulethe amasuntswana. Sombulula iimpazamo ezininzi zempompo ezizitshixayo zemveli. Olu hlobo lwempompo ezizitshixayo luyinkqubo yokusebenza eyomileyo engaqhelekanga kwaye luza kuqala ngokuzenzekelayo ngaphandle kolwelo ekuqaleni, intloko yokufunxa inokuba ngaphezulu kwe-9 m; Uyilo oluhle kakhulu lwe-hydraulic kunye nesakhiwo esikhethekileyo sigcina ukusebenza okuphezulu kungaphezulu kwe-75%. Kwaye ukufakelwa kwesakhiwo okwahlukileyo kokuzikhethela.
I-Piezometer
IUkucofa i-fa kwenziwa kumphezulu womda kwaye ityhubhu ende ngokwaneleyo iqhagamshelwe, ulwelo luya kunyuka kwityhubhu de lulungelelaniswe ngumoya. Uxinzelelo olukwindawo ephambili yolwelo lumelwe kukuphakama okuthe nkqo kwekholamu yolwelo. Ngokucacileyo, isixhobo sifanelekile kuphela kuxinzelelo oluphakathi, kungenjalo ulwelo luya kunyuka kakhulu kwityhubhu ye-piezometer ukuze kube lula ukulinganisa.
Umfanekiso 6. Izixhobo zokulinganisa uxinzelelo
Xa ulwelo luhamba, ukuthepha kwe-piezometer akufuneki kudlule ububanzi be-3 mm kwaye kufuneka kuhlanjululwe kumphezulu womda. Ukuze kube ngokuchanekileyo ngakumbi, kunokufakelwa iringi ye-piezometer. Oku kuquka igumbi elijikelezileyo elijikeleze umbhobho kwaye liqhagamshelwe kulo ngamanani okuthepha alinganayo.
I-Manometer
IManometer Lo mgaqo uyafana nalowo uchazwe apha ngasentla, kodwa ubunzima obunxulumene netyhubhu ende kakhulu buyasoyiswa ngokufaka ityhubhu ye-U equlethe ulwelo olungaxutywanga. I-Mercury (ubunzima obuthile 13,6) lulwelo lwe-manometer oludla ngokusetyenziswa ukulinganisa uxinzelelo lwamanzi. I-gauge pressure p kwipayipi inikwa yi
Phi
h= umahluko kwinqanaba lolwelo lwe-manometer kumalungu omabini,
z= ukuphakama komgca ophakathi wepayipi ngaphezulu kwe-meniscus kwilungu kwicala lepayipi, kunye
w, wm = ubunzima obuthile bolwelo lombhobho kunye nolwelo lwe-manometer ngokulandelelana.
iphiko ukuya kwiindawo ezitshintshatshintshayo ze-menisci, ukulinganiswa ngokuthe ngqo akunakwenzeka. Nangona kunjalo, oku kunokufezekiswa ukuba ilungu elikwicala lombhobho landiswe kakhulu ukuze inqanaba le-meniscus lihlale lifana. Uxinzelelo lunokufundwa kwisikali esimiselweyo esiqhotyoshelwe kwelinye ilungu.
Fig.7. I-manometer eyahlukileyo
Uvavanyo lobungakanani bokuhamba kombhobho ludla ngokusekwe ekulinganisweni komahluko woxinzelelo phakathi kokucofa okukufutshane. Kusetyenziswa i-manometer eyahlukileyo (Umz. 7) kwaye ulwelo lwe-manometer ludla ngokuba yi-mercury. Xa umahluko woxinzelelo umncinci, ulwelo olukhaphukhaphu olungenakuxutywa luya kuvelisa iziphumo ezichanekileyo ngakumbi.
Umahluko woxinzelelo lwe-pt-pzis olunikwe ngu
apho iimpawu zinentsingiselo efanayo nekwiSilinganiso 6. Ukuba umbhobho ungqindililial,
Ii-manometers ezahlukeneyo zohlobo oluntsonkothileyo ziye zayilwa ukuhlangabezana neemfuno ezithile zomsebenzi wezorhwebo nowelebhu.
Bi-ourdon gauge
Esi sisixhobo sorhwebo esifakelwe ngqo kumbhobho ngokwawo okanye ekupheleni komgca we-piezometer. Siqulathe ityhubhu egobileyo exhonywe ngokukhululekileyo kwicandelo eligobileyo kwaye ibanjwe ngokuqinileyo kwisiqu. Ukwanda koxinzelelo lwangaphakathi kudla ngokulungisa ityhubhu kwaye, njengoko ukuphambuka kuhambelana ngqo noxinzelelo olusetyenzisiweyo, indlela elula ivumela ukuba le yokugqibela irekhodwe ngokuthe ngqo. Ekubeni uxinzelelo olungaphandle kwetyhubhu lunomoya, uxinzelelo lwegeyiji luyabhaliswa kwaye oku kudla ngokusebenza kwindawo ephakathi yesixhobo.
I-Bourdon gauge iluncedo njengesalathisi esiqhelekileyo soxinzelelo kodwa ayifanelekanga apho kufuneka ukuchaneka okukhulu, njengoko kunjalo ngokubanzi xa kufuneka kulinganiswe uxinzelelo olwahlukileyo.
