Madzi Osasintha
Hydrostatic ndi nthambi ya makina amadzimadzi omwe ali ndi mphamvucernYopangidwa ndi madzi panthawi yopuma. Monga tafotokozera kale, palibe kupsinjika kwa tangential kapena shear komwe kulipo pakati pa tinthu tamadzi tosakhazikika.
Motero mu hydrostatic, mphamvu zonse zimagwira ntchito bwino pamalo ozungulira ndipo sizimayenderana ndi kukhuthala. Zotsatira zake, malamulo owongolera ndi osavuta, ndipo kusanthula kumachokera pakugwiritsa ntchito mosavuta mfundo zamakina za mphamvu ndi mphindi. Mayankho ndi olondola popanda chifukwa choyesera.
Pampu Yoyimirira Yopangira Mphamvu
Injini ya Dizilo Vertical Turbine multistage centrifugal inline shaft water Pump Drainage Pump yamtunduwu imagwiritsidwa ntchito makamaka popopera madzi opanda dzimbiri, kutentha kwake kuli pansi pa 60 °C, zinthu zolimba zomwe zimapachikidwa (osaphatikizapo ulusi, grits) zosakwana 150 mg/L mu zimbudzi kapena madzi otayira. Pump ya mtundu wa VTP vertical drainage ili mu mapampu amadzi otayira a mtundu wa VTP, ndipo potengera kuchuluka ndi kolala, mafuta odzola amayikidwa mu chubu. Ikhoza kusuta kutentha kochepera 60 °C, kutumiza kuti ikhale ndi tinthu tating'onoting'ono tolimba (monga chitsulo chodulidwa ndi mchenga wabwino, malasha, ndi zina zotero) za zimbudzi kapena madzi otayira.
Kupanikizika kwamphamvu
Mphamvu ya kupanikizika kapena, mwachidule, kupanikizika pamwamba ndi mphamvu ya kupanikizika pa gawo lililonse. Mu Chithunzi 4, mphamvu ya kupanikizika yotsika yoyimirira ikugwira ntchito mopingasa
Lamina ndi yofanana ndi kulemera kwa prism ya madzi pamwamba pake, kuphatikiza mphamvu ya kupanikizika pamalo olumikizirana ndi madzi ena. Kuti pakhale kukhazikika kwa static payenera kukhala kupanikizika kofanana kokwera pansi pa lamina. Ngati madzi osagwedezeka akhudzana ndi mlengalenga, kupanikizika kwa gauge p (mu pascals) kumaperekedwa ndi
kumene w ndi kulemera kwa madzi ndipo h ndi kuya pansi pa malo omasuka. Chomalizachi chimatchedwa kuti press-

Mutu wotsimikizika ndipo nthawi zambiri umafotokozedwa mu mamita a madzi. Kapangidwe ka equation kamasonyeza kuti kuthamanga kumawonjezeka molunjika ndi kuya. Popeza mphamvu yokoka ndi katundu weniweni womwe umakhudzidwa, pamwamba pa madzi osagwedezeka nthawi zonse pamakhala mopingasa ndipo mphamvu ya kuthamanga ndi yofanana pa ndege iliyonse yopingasa mkati mwa thupi la madzi. Kuphatikiza apo, zitha kuwonetsedwa kuti mphamvu ya kuthamanga pa tinthu tating'onoting'ono ta elemental ndi yofanana mbali zonse. Izi zikutsatira kuchokera ku kuganizira mphamvu za kuthamanga zomwe zimagwira ntchito pa prism yooneka ngati triangular (Chithunzi 5) ya kutalika kopingasa kwa unit, yokhala ndi miyeso ya magawo δ.l,δx,δy, ndi kulemera δw.

Kuti pakhale kufanana munjira yopingasa,
Mofananamo m'njira yolunjika,
kunyalanyaza malamulo achiwiri a kuchuluka kochepa kwambiri,
Chifukwa chake, mphamvu ya kupanikizika siidalira ngodya ya pamwamba pa chinthucho ndipo ndi yofanana mbali zonse.
Kuyeza kuthamanga
Tmitundu ya chipangizo
Pankhani ya zakumwa zokhala ndi malo omasuka, pressMadziwo akamatsekedwa kwathunthu, monga m'mapaipi ndi njira zoyendetsera mpweya, kuthamanga kwa mpweya sikungatheke kudziwika ndipo chipangizo choyenera choyezera chimafunika. Pali mitundu itatu yayikulu: (a) piezometer, (b) manometer, ndi (c) Bourdon gauge. Izi zikuwonetsedwa kuti zayikidwa paipi mu Chithunzi 6.
Pumpu yopangira chitsime cha vacuum
Nambala ya Chitsanzo: TWP
Mapampu amadzi a injini ya dizilo oyenda okha a TWP odzipangira okha ntchito zadzidzidzi amapangidwa ndi DRAKOS PUMP ya ku Singapore ndi kampani ya REEOFLO ya ku Germany. Pampu iyi imatha kunyamula mitundu yonse ya tinthu tating'onoting'ono toyera, topanda ndale komanso towononga tomwe tili ndi tinthu tating'onoting'ono. Kuthetsa mavuto ambiri achikhalidwe a pampu yodzipangira yokha. Mtundu uwu wa pampu yodzipangira yokha ndi kapangidwe kake kouma komwe kamakhala koyambira kokha komanso koyambitsanso popanda madzi poyambira koyamba, Mutu wokoka ukhoza kukhala woposa 9 m; Kapangidwe kabwino kwambiri ka hydraulic ndi kapangidwe kake kapadera kamapangitsa kuti magwiridwe antchito apamwamba akhale opitilira 75%. Ndipo kuyika kwa kapangidwe kosiyana ndi kwina kulikonse kosankha.
Piezometer
IKugwira fa kumapangidwa pamwamba pa malire ndipo chubu cholumikizidwa bwino, madziwo adzakwera mu chubucho mpaka atakhazikika ndi mphamvu ya mlengalenga. Kupanikizika m'thupi lalikulu la madziwo kumaimiridwa ndi kutalika koyima kwa mzere wamadziwo. Mwachionekere, chipangizochi ndi choyenera kokha kupsinjika pang'ono, apo ayi madziwo adzakwera kwambiri mu chubu cha piezometer kuti muyeze mosavuta.
Chithunzi 6. Zipangizo zoyezera kuthamanga
Madzi akamayenda, kugogoda kwa piezometer sikuyenera kupitirira 3 mm m'mimba mwake ndipo kuyenera kukhala kosalala ndi malire. Kuti zikhale zolondola kwambiri, mphete ya piezometer ikhoza kuyikidwa. Izi zimakhala ndi chipinda chozungulira chitolirocho ndikulumikizidwa nacho ndi kugogoda kofanana.
Manometer
Manometer Mfundo yake ndi yofanana ndi yomwe yafotokozedwa pamwambapa, koma mavuto okhudzana ndi chubu chachitali kwambiri amatha kuthetsedwa poyika chubu cha U chokhala ndi madzi osasakanikirana. Mercury (mphamvu yokoka 13,6) ndi madzi a manometer omwe nthawi zambiri amagwiritsidwa ntchito poyesa kuthamanga kwa madzi. Kuthamanga kwa gauge p mupayipi kumaperekedwa ndi

h = kusiyana kwa mulingo wa madzi a manometer m'miyendo iwiri,
z = kutalika kwa mzere wapakati wa chitoliro pamwamba pa meniscus m'mbali mwa chitoliro, ndi
w, wm = kulemera kwapadera kwa madzi a chitoliro ndi manometer motsatana.
Kutengera malo osinthasintha a menisci, kulinganiza mwachindunji sikungatheke. Komabe, izi zitha kuchitika ngati nthambi yomwe ili kumbali ya chitoliro yakulitsidwa kwambiri kotero kuti mulingo wa meniscus ukhalebe wofanana. Kupanikizika kumatha kuwerengedwa kuchokera pa sikelo yomaliza yolumikizidwa ku nthambi inayo.
Fig.7. Manometer yosiyana
Kuwunika kuchuluka kwa kayendedwe ka mapaipi nthawi zambiri kumadalira muyeso wa kusiyana kwa kuthamanga pakati pa kugogoda kwapafupi. Manometer osiyana (Chithunzi 7) amagwiritsidwa ntchito ndipo madzi a manometer nthawi zambiri amakhala mercury. Ngati kusiyana kwa kuthamanga kuli kochepa, madzi opepuka osasakanikirana amapereka zotsatira zolondola kwambiri.
Kusiyana kwa kupanikizika kwa pt- pzis komwe kwaperekedwa ndi
kumene zizindikirozo zili ndi tanthauzo lofanana ndi la mu Equation 6. Ngati chitoliro chili chopingasaal,
Ma manometer osiyanasiyana ovuta kwambiri apangidwa kuti akwaniritse zosowa zenizeni zamakampani ndi ma labotale.
Bourdon gauge
Ichi ndi chida chamalonda chomwe chimayikidwa mwachindunji ku chitolirocho kapena kumapeto kwa mzere wa piezometer. Chimakhala ndi chubu chopindika chomwe chimapachikidwa momasuka mu gawo lopindika ndikugwiridwa molimba pa tsinde. Kuwonjezeka kwa kupanikizika kwamkati kumayambitsa kuwongola chubucho ndipo, popeza kupatuka kumagwirizana mwachindunji ndi kupsinjika komwe kumagwiritsidwa ntchito, njira yosavuta imalola kuti chomalizacho chilembedwe mwachindunji. Popeza kupanikizika kunja kwa chubucho kuli mumlengalenga, kupanikizika koyezera kumalembedwa ndipo nthawi zambiri izi zimagwiritsidwa ntchito pakati pa chidacho.
Gauge ya Bourdon ndi yothandiza ngati chizindikiro cha kuthamanga kwa magazi koma si yoyenera pamene pakufunika kulondola kwakukulu, monga momwe zimakhalira nthawi zambiri pamene kuthamanga kwa magazi kosiyana kumafunika kuyezedwa.
Pampu Yozimitsa Moto Yoyimitsa Turbine
Nambala ya Chitsanzo: XBC-VTP
Mapampu olimbana ndi moto a XBC-VTP Series okhala ndi shaft yayitali ndi mndandanda wa mapampu otulutsa mpweya wa siteji imodzi, okhala ndi masitepe ambiri, opangidwa motsatira muyezo waposachedwa wa National Standard GB6245-2006. Tinakonzanso kapangidwe kake pogwiritsa ntchito muyezo wa United States Fire Protection Association. Amagwiritsidwa ntchito makamaka popereka madzi a moto m'mafakitale a petrochemical, gasi lachilengedwe, malo opangira magetsi, nsalu za thonje, doko, ndege, malo osungiramo zinthu, nyumba zazitali komanso mafakitale ena. Itha kugwiritsidwanso ntchito pa sitima, thanki yamadzi, sitima yamoto ndi zochitika zina zoperekera madzi.
Pampu Yopita Kumadzi a Nyanja ya Centrifugal
