I-Hydrostatic
IHydrostatic lisebe lobuchwephesha bolwelo oluyi-concerned kunye nolwelo xa uphumle.Njengoko bekutshiwo ngaphambili, akukho xinzelelo lwe-tangential okanye lokucheba lukhoyo phakathi kwamasuntswana olwelo olumileyo.
Ngaloo ndlela kwi-hydrostatic, zonke imikhosi zisebenza ngokuqhelekileyo kumda womda kwaye zizimeleyo kwi-viscosity.Ngenxa yoko, imithetho yokulawula ilula, kwaye uhlalutyo lusekelwe kwisicelo esicacileyo semigaqo yomatshini yamandla kunye nomzuzu.Izisombululo zichanekile kwaye akukho mfuneko yokuba ufune ukulinga.
I-injini yedizili ethe nkqo iTurbine yenqanaba le-centrifugal emgqeni weshafti yamanzi Impompo yokukhupha amanzi ilindle okanye amanzi amdaka.Uhlobo lwe-VTP yempompo yokukhupha amanzi ethe nkqo ikwi-VTP yohlobo lweempompo zamanzi ezithe nkqo, kwaye ngesiseko sokwanda kunye nekhola, seta i-tube oil lubrication ngamanzi.Inokutshaya iqondo lobushushu elingaphantsi kwe-60 °C, ithumele ukuqulatha iinkozo ezithile eziqinileyo (ezifana nentsimbi elahliweyo nesanti ecolekileyo, amalahle, njl.njl.) yamanzi amdaka okanye amdaka.
Ukuqina koxinzelelo
Ukunyanzeliswa koxinzelelo okanye, ngokulula ngakumbi, uxinzelelo oluphezu komhlaba luxinzelelo lwamandla kwindawo nganye yeyunithi.KuMzobo 4, amandla oxinzelelo oluthe nkqo asezantsi asebenza ngokuthe tye
i-lamina ilingana nobunzima beprism yolwelo ngokuthe nkqo phezu kwayo, kunye noxinzelelo loxinzelelo kujongano nolunye ulwelo.Ulungelelwaniso lwe-static kufuneka kubekho uxinzelelo oluhambelanayo oluya phezulu oluthe nkqo ngaphantsi kwe-lamina.Kwimeko yolwelo olungenakucinezeleka xa ludibana nomoya, igeyiji yoxinzelelo lwe-p (kwi-pascals) inikwa
apho u-w bubunzima obuthile bolwelo kwaye u-h bubunzulu obungaphantsi komhlaba okhululekileyo.Le yokugqibela ibizwa ngokuba yi-pres-
Fig.4.Amandla oxinzelelo kwi-lamina ethe tye entywiliselwe emanzini
intloko eqinisekileyo kwaye ixelwe ngokubanzi ngeemitha zolwelo.Ifom ye-equation ibonisa ukuba uxinzelelo luyanda ngokuhambelana nobunzulu.Njengoko umxhuzulane uyipropathi ebonakalayo ebandakanyekayo, umphezulu okhululekileyo wolwelo olumileyo usoloko uthe tyaba kwaye ukuqina koxinzelelo kuyafana kuyo nayiphi na inqwelomoya ethe tye ngaphakathi emzimbeni wolwelo.Ngaphezu koko, kunokuboniswa ukuba ukuqina koxinzelelo kuyo nayiphi na i-elemental particle iyafana kuzo zonke iinkalo.Oku kulandela uqwalaselo lwamandla oxinzelelo asebenza kwiprism emilise okonxantathu (Fig.5) yobude obuthe tye, kunye nemilinganiselo yecandelo δl,δx,δy, kunye nobunzima δw.

Ulungelelwaniso kwicala elithe tye,
Ngokufanayo kwicala elithe nkqo,
ukutyeshela imimiselo yodidi lwesibini lwemilinganiselo emincinci kakhulu,
Ngaloo ndlela Uxinzelelo loxinzelelo luxhomekeke kwi-angle ye-inclination ye-elemental surface kwaye iyafana kuzo zonke iindlela.
Umlinganiselo woxinzelelo
Tiintlobo zesixhobo
Kwimeko yolwelo olunomphezulu okhululekileyo, i-pressure nakweyiphi na indawo imelwe bubunzulu obungaphantsi komhlaba.Xa ulwelo luvalekile ngokupheleleyo, njengakwimibhobho kunye nemibhobho yoxinzelelo, uxinzelelo alunakuqinisekiswa kwaye isixhobo esifanelekileyo sokulinganisa siyafuneka.Kukho iintlobo ezintathu eziphambili: (a) ipiezometer, (b) i-manometer, kunye (c) ne-Bourdon gauge.Ezi zibonisiwe zifakwe kumbhobho kuMfanekiso 6.
Vacuum yempompo yomthombo wentsusa
Inombolo yomzekelo: TWP
TWP uthotho lwe-Movable Diesel Engine self-priming Well point Iipompo zaManzi ezingxamisekileyo zidityaniswe yiDRAKOS PUMP yaseSingapore kunye neREEOFLO inkampani yaseJamani.Olu luhlu lwempompo lunokuthutha zonke iintlobo zokucoca, ukungathathi hlangothi kunye ne-corrosive medium equkethe amasuntswana.Sombulula iziphene ezininzi zempompo zokuziqala.Olu hlobo impompo self-priming isakhiwo eyomileyo esebenzayo iya kuba uqalo oluzenzekelayo kwaye uqale ngokutsha ngaphandle ulwelo ekuqaleni kokuqala, Intloko yokufunxa inokuba ngaphezu kwe-9 m;Uyilo olugqwesileyo lwe-hydraulic kunye nesakhiwo esikhethekileyo sigcina ukusebenza okuphezulu ngaphezulu kwe-75%.Kunye ufakelo olwahlukileyo lwesakhiwo ngokuzikhethela.
Ipiezometer
IUkucofa kwe-fa kwenziwa kumda womda kunye netyhubhu ende ngokwaneleyo edityanisiweyo, ulwelo luya kunyuka kwi-tube de lulungelelaniswe luxinzelelo lwe-atmospheric.Uxinzelelo kumzimba oyintloko wolwelo umelwe kukuphakama okuthe nkqo kwikholamu yolwelo.Ngokucacileyo, isixhobo sifanelekile kuphela kuxinzelelo oluphakathi, ngaphandle koko i-liquid iya kunyuka kakhulu kwi-tube ye-piezometer yokulinganisa okulula.
Fig.6.Izixhobo zokulinganisa uxinzelelo
Xa i-liquid ihamba, ukucofa kwe-piezometer akufanele kudlule ububanzi be-3 mm kwaye kufuneka kuhlanjululwe kunye nomda womda.Ukuchaneka okukhulu, i-piezometer ring inokuthi ifakwe.Oku kubandakanya igumbi le-annular elijikeleze umbhobho kwaye lixhunywe kuyo ngamanani alinganayo alinganayo.
Imanometer
I-Manometer Umgaqo ufana naleyo ichazwe ngasentla, kodwa ubunzima obunxulumene nombhobho omde ngokugqithisileyo bunqotshwa ngokufaka i-U-tube equlethe ulwelo olungenakulinganiswa.I-Mercury (i-gravity ethile 13,6) ngulwelo lwe-manometer oluhlala lusetyenziselwa ukulinganisa uxinzelelo lwamanzi.Uxinzelelo lwegeyiji p kumbhobho lunikezelwa ngu
Apho
h = umahluko kwinqanaba le-manometer engamanzi kumalungu amabini,
z=ubude bomgca osembindini wombhobho ngaphezu kwe-meniscus kwilungu kwicala lombhobho, kunye
w, wm = ubunzima obuthile bombhobho kunye ne-manometer liquids ngokulandelanayo.
iphiko kwiindawo eziguquguqukayo ze-menisci, ukulinganisa ngokuthe ngqo akunakwenzeka.Nangona kunjalo, oku kunokufezekiswa ukuba ilungu kwicala lombhobho likhuliswe kakhulu ukwenzela ukuba inqanaba le-meniscus lihlale lihlala lihlala lihlala lihleli.Iingcinezelo zinokufundwa kumlinganiselo ophumeleleyo odityaniswe kwelinye isebe.
Fumz.7.I-manometer eyahlukileyo
Uvandlakanyo lobungakanani bokuhamba kombhobho luhlala lusekwe kumlinganiso womahluko woxinzelelo phakathi kweetephu ezikufutshane.I-manometer eyahlukileyo (Umfanekiso 7) iqeshwe kwaye i-manometer liquid idla ngokuba yi-mercury.Xa iiyantlukwano zoxinzelelo zincinci, i-lighter immiscible liquid iya kunika iziphumo ezichanekileyo.
Umahluko woxinzelelo pt- pzis onikwe ngu
apho iisimboli zinentsingiselo efanayo naleyo iku-Equation 6. Ukuba umbhobho uthe tyeal,
Ii-manometers ezihlukeneyo zendalo eyinkimbinkimbi ziye zayilwa ukuhlangabezana neemfuno ezithile zorhwebo kunye nokusebenza kwebhubhoratri.
Byethudon gauge
Esi sixhobo sorhwebo esifakwe ngokuthe ngqo kumbhobho ngokwawo okanye ekupheleni komgca we-piezometer.Iqukethe ityhubhu egobileyo emiswe ngokukhululekileyo kwisahlulo esigobileyo kwaye ibanjwe ngokungqongqo kwisiqu.Ukunyuka koxinzelelo lwangaphakathi kudla ukulungisa ityhubhu kwaye, njengoko ukuphambuka kuhambelana ngokuthe ngqo noxinzelelo olusetyenzisiweyo, indlela elula yenza ukuba le yokugqibela ibhalwe ngokuthe ngqo.Ekubeni uxinzelelo olungaphandle kombhobho luyi-atmospheric, uxinzelelo lwe-gauge lubhalisiwe kwaye oku ngokuqhelekileyo kusebenza kwindawo ephakathi kwesixhobo.
I-Bourdon gauge iluncedo njengesalathiso esiqhelekileyo soxinzelelo kodwa ayifanelekanga apho kufunwa ukuchaneka okubonakalayo, njengoko ngokuqhelekileyo kunjalo xa uxinzelelo oluhlukeneyo kufuneka lulinganiswe.
Impompo yoMlilo yeTurbine ethe nkqo
Inombolo yomzekelo: XBC-VTP
XBC-VTP Series nkqo iimpompo zokulwa umlilo kwishaft elide ziluthotho lweqonga elinye, iimpompo diffusers multistage, eveliswe ngokuhambelana yamva nje Standard Standard GB6245-2006.Sikwaphucule uyilo ngokubhekisele kumgangatho we-United States Fire Protection Association.Isetyenziselwa kakhulu ukubonelela ngamanzi omlilo kwi-petrochemical, igesi yendalo, iplanti yamandla, i-cotton textile, i-wharf, i-aviation, i-warehousing, isakhiwo esiphakamileyo kunye namanye amashishini.Isenokuthi isebenze kwinqanawa, itanki yolwandle, inqanawa yomlilo kunye nezinye izihlandlo zokubonelela.
Impompo yokuSinga amanzi oLwandle lwase-Centrifugal
Inombolo yomzekelo:ASN ASNV
Iimpompo zemodeli ye-ASN kunye ne-ASNV zinenqanaba elinye lokufunxa kabini ukwahlula iimpompo ze-volute casing centrifugal kwaye zisetyenzisiwe okanye ukuthuthwa kolwelo kwimisebenzi yamanzi, ukujikeleza komoya-moya, ukwakhiwa, ukunkcenkceshela, isikhululo sokumpompa amanzi, isikhululo samandla ombane, inkqubo yonikezelo lwamanzi kwimizi mveliso, ukulwa nomlilo. inkqubo, inqanawa, isakhiwo njalo njalo.
