Mvura inochinja-chinja
Hydrostatic ibazi remakanika emvura iro rinoshandacernYakasanganiswa nemvura panguva yekuzorora. Sezvambotaurwa, hapana kushushikana kwetangential kana shear kuripo pakati pezvikamu zvemvura zvisina kumira.
Saka mu hydrostatic, masimba ese anoshanda zvakajairika kune imwe nzvimbo uye haana kusimba. Nekuda kweizvozvo, mitemo yekudzora iri nyore, uye ongororo yakavakirwa pakushandiswa kwakananga kwemisimboti yesimba nenguva. Mhinduro dzakanyatsojeka pasina chikonzero chekuyedza.
Injini yedhiziri Vertical Turbine multistage centrifugal inline shaft water Drainage Pump Rudzi urwu rwepombi yemvura inoyerera inoshandiswa zvakanyanya pakupomba isina ngura, tembiricha iri pasi pe60 °C, zvinhu zvakasimba zvakasungirirwa (kusasanganisira fiber, grits) pasi pe150 mg/L yemvura yetsvina kana tsvina. Pombi yemvura inoyerera yemhando yeVTP iri mumapombi emvura anotenderera emhando yeVTP, uye zvichibva pakuwedzera uye kora, chubhu inoisa mafuta emafuta mumvura. Inogona kupfungaira tembiricha iri pasi pe60 °C, kutumira kuti ive netsanga yakasimba (senge simbi yakapwanyika nejecha rakanaka, marasha, nezvimwewo) yetsvina kana mvura yakasviba.
Kumanikidzwa kwakanyanya
Kusimba kwekumanikidzwa kana, zviri nyore, kumanikidzwa pamusoro pechinhu isimba rekumanikidzwa pachikamu chimwe nechimwe. MuMufananidzo 4, simba rekumanikidzwa rinodzika rakamira richishanda pamutsetse wakatwasuka

Kuyerwa kwekumanikidzwa
Tmhando dzemudziyo
Kana paine zvinwiwa zvine pamusoro wakasununguka, pressChero papi zvapo panomiririrwa nekudzika kuri pasi pemvura. Kana mvura yacho yakavharwa zvachose, sezvakaita mumapaipi nemakombi ekumanikidza, kumanikidzwa hakugone kuonekwa zviri nyore uye mudziyo wekuyera wakakodzera unodiwa. Kune mhando nhatu huru: (a) piezometer, (b) manometer, uye (c) Bourdon gauge. Izvi zvinoratidzwa zvakaiswa papaipi muMufananidzo 6.
Pombi yekuisa pombi yemvura inotonhorera
Nhamba yeModhero: TWP
Mapombi emvura eTWP akatevedzana anofambiswa neInjini yeDiesel inozvigadzira ega. Mapombi emvura eWellpoint ekukurumidza akagadzirwa pamwe chete neDRAKOS PUMP yeSingapore nekambani yeREEOFLO yeGermany. Pombi iyi inogona kutakura marudzi ese enzvimbo yakachena, isina divi uye inoparadza ine zvidimbu. Gadzirisa zvikanganiso zvakawanda zvechinyakare zvepombi inozvigadzira yega. Rudzi urwu rwepombi inozvigadzira yega chimiro chakasarudzika chekushanda chakaoma chichatanga otomatiki uye kutangazve pasina mvura yekutanga, Musoro wekusveta unogona kupfuura 9 m; Dhizaini yakanaka ye hydraulic uye chimiro chakasarudzika chinochengetedza kushanda kwepamusoro kupfuura 75%. Uye kuiswa kwechimiro chakasiyana kune sarudzo.
Piezometer
IKubata-bata kwefa kunoitwa pamusoro pemuganhu uye chubhu yakareba zvakakwana yakabatana, mvura inokwira muchubhu kusvika yaenzana nekumanikidzwa kwemhepo. Kumanikidzwa kuri mumuviri mukuru wemvura kunomiririrwa nekukwirira kwakamira kwekoramu yemvura. Zviri pachena kuti mudziyo wacho wakakodzera chete kumanikidzwa kuri pakati nepakati, zvikasadaro mvura inokwira zvakanyanya muchubhu yepiezometer kuti ive nyore kuyerwa.
Mufananidzo 6. Zvishandiso zvekuyera kumanikidzwa
Kana mvura iri kuyerera, piezometer tapping haifanirwe kudarika dhayamita ye3 mm uye inofanira kuyerera nepamusoro pemuganhu. Kuti zvive nyore, ring yepiezometer inogona kuiswa. Izvi zvinosanganisira kamuri rinotenderera pombi uye rakabatana naro nematanho akasiyana-siyana.
Manometer
Manometer Pfungwa yacho yakafanana neyatsanangurwa pamusoro apa, asi matambudziko ane chekuita nechubhu refu zvakanyanya anokundwa nekuisa chubhu yeU ine mvura isingasanganisike. Mercury (yakakosha gravity 13,6) imvura yemanometer inowanzo shandiswa kuyera kumanikidzwa kwemvura. Gauge pressure p iri mupaipi inopiwa ne

Kuongororwa kwehuwandu hwekufamba kwepombi kunowanzo shandiswa pakuyera musiyano wekumanikidzwa pakati pemapombi ari pedyo. Muchina wemanometer wakasiyana (Mufananidzo 7) unoshandiswa uye mvura yemanometer inowanzova mercury. Kana musiyano wekumanikidzwa uri mudiki, mvura yakareruka isingasanganisike inopa mhedzisiro chaiyo.
Musiyano wekumanikidzwa kwe pt- pzis unopiwa na

Manometer akasiyana-siyana akaomarara akagadzirwa kuti agutse zvinodiwa zvemabhizinesi nemabasa emurabhoritari.
Bourdon gauge
Ichi chishandiso chekutengeserana chinoiswa zvakananga papombi pachayo kana kumagumo kwetambo yepiezometer. Chine chubhu yakakombama yakasungirirwa zvakasununguka muchikamu chakakombama uye inobatwa zvakasimba padanda. Kuwedzera kwekumanikidzwa kwemukati kunowanzoita kuti chubhu irurame uye, sezvo kutsauka kwacho kwakaenzana zvakananga nekumanikidzwa kuri kushandiswa, nzira iri nyore inoita kuti yekupedzisira inyorerwe zvakananga. Sezvo kumanikidzwa kuri kunze kwechubhu kuri mumhepo, kumanikidzwa kwegeji kunonyoreswa uye izvi zvinowanzo shanda pakati pechishandiso.
Bourdon gauge inobatsira sechiratidzo chekumanikidzwa asi haikodzeri kana paine kurongeka kwakawanda, sezvinowanzoitika kana kumanikidzwa kwakasiyana-siyana kuchizoyerwa.
