HYDROSTATIC TSHUAB

Hydrostatic

Hydrostatic yog cov ceg ntawm cov dej mechanics uas yog concerned nrog kua thaum so. Raws li tau hais dhau los, tsis muaj tangential lossis shear stress tshwm sim ntawm cov kua dej nyob ruaj khov.

Yog li hauv hydrostatic, txhua lub zog ua haujlwm ib txwm ua rau thaj tsam ntawm thaj tsam thiab tsis muaj viscosity. Yog li ntawd, cov kev cai tswjfwm yog qhov yooj yim, thiab kev tshuaj xyuas yog ua raws li kev ncaj ncees ntawm kev siv tshuab ntawm lub zog thiab lub sijhawm. Cov kev daws teeb meem yog qhov tseeb uas tsis tas yuav muaj kev rov qab los rau kev sim.

Vertical Turbine Pump

Diesel cav Vertical Turbine multistage centrifugal inline shaft dej Drainage Pump Hom twj tso kua dej ntsug no feem ntau yog siv rau kev siv tsis muaj corrosion, kub tsawg dua 60 ° C, tshem tawm cov khib nyiab (tsis suav nrog fiber ntau, cov grits) tsawg dua 150 mg / L cov ntsiab lus ntawm cov dej phwj los yog dej khib nyiab. VTP hom ntsug dej twj tso kua mis yog nyob rau hauv VTP hom ntsug dej twj tso kua mis, thiab nyob rau hauv lub hauv paus ntawm qhov nce thiab lub dab tshos, teem lub raj roj lubrication yog dej. Muaj peev xwm haus luam yeeb kub hauv qab 60 ° C, xa kom muaj cov khoom nplej (xws li cov hlau nplaum thiab cov xuab zeb zoo, thee, thiab lwm yam) ntawm cov dej phwj tuaj lossis dej pov tseg.

Siab siv zog

Lub siab siv los yog, yooj yim dua, lub siab ntawm qhov chaw yog lub zog quab yuam ntawm ib cheeb tsam. Nyob rau hauv daim duab 4, ntsug downward siab quab yuam ua rau kab rov tav

lamina yog sib npaug rau qhov loj ntawm lub prism ntawm cov kua vertically saum nws, ntxiv rau lub siab siv ntawm lub interface nrog rau lwm cov kua. Rau static equilibrium yuav tsum muaj ib tug sib xws upward ntsug siab hauv qab lub lamina. Nyob rau hauv cov ntaub ntawv ntawm ib tug incompressible kua nyob rau hauv kev sib cuag nrog cov cua, lub gauge siab p (hauv pascals) yog muab los ntawm

paub meej lub taub hau thiab feem ntau teev nyob rau hauv meters ntawm kua. Daim ntawv ntawm kab zauv qhia tau hais tias lub siab nce linearly nrog qhov tob. Raws li lub ntiajteb txawj nqus yog cov cuab yeej ntawm lub cev uas koom nrog, qhov chaw dawb ntawm cov kua tseem yog ib txwm kab rov tav thiab lub siab siv tib yam ntawm txhua lub dav hlau kab rov tav hauv lub cev ntawm cov kua. Tsis tas li ntawd, nws yuav pom tau tias qhov kev siv lub zog ntawm txhua lub ntsiab lus yog tib yam hauv txhua qhov kev qhia. Qhov no ua raws li los ntawm kev txiav txim siab ntawm lub zog siab ua haujlwm ntawm lub hauv paus ntawm daim duab peb sab zoo li lub prism (Fig.5) ntawm chav tsev kab rov tav ntev, nrog rau seem seem δl, δx, d y, thiab mass δ w.

Kev ntsuas siab

Types of device

Nyob rau hauv cov ntaub ntawv ntawm cov kua nrog ib tug dawb nto, lub pressure ntawm txhua qhov taw tes yog sawv cev los ntawm qhov tob hauv qab ntawm qhov chaw.Thaum cov kua ua kom tag nrho, xws li hauv cov kav dej thiab cov kav dej siab, lub siab tsis tuaj yeem paub tseeb thiab yuav tsum muaj cov cuab yeej ntsuas tsim nyog. Muaj peb yam tseem ceeb: (a) piezometer, (b) manometer, thiab (c) Bourdon gauge. Cov no tau pom tias haum rau lub raj xa dej hauv daim duab 6.

Nqus Priming zoo point twj tso kua mis

Model No: TWS

TWP series Movable Diesel Cav self-priming Well point Dej twj rau thaum muaj xwm ceev yog sib koom tsim los ntawm DRAKOS PUMP ntawm Singapore thiab REEOFLO lub tuam txhab ntawm lub teb chaws Yelemees. Cov twj tso kua mis no tuaj yeem thauj txhua yam huv, nruab nrab thiab corrosive nruab nrab uas muaj cov khoom. Txhim kho ntau cov tsoos self-priming twj faults. Qhov no hom ntawm tus kheej-priming twj tso kua mis tshwj xeeb qhuav khiav qauv yuav tsis siv neeg pib thiab rov pib dua yam tsis muaj kua rau thawj zaug, Lub taub hau nqus tau ntau tshaj 9 m; Cov qauv hydraulic zoo heev thiab cov qauv tshwj xeeb khaws cov kev ua haujlwm siab tshaj 75%. Thiab txawv qauv installation rau kev xaiv.

Piezometer

Ifa tapping yog tsim nyob rau hauv ciam teb nto thiab ib tug txaus ntev raj txuas, cov kua yuav nce nyob rau hauv lub raj kom txog thaum sib npaug ntawm atmospheric siab. Lub siab nyob rau hauv lub ntsiab lub cev ntawm cov kua yog sawv cev los ntawm ntsug qhov siab ntawm cov kua kem. Kom meej meej, cov cuab yeej tsuas yog haum rau nruab nrab siab, txwv tsis pub cov kua yuav nce siab dhau ntawm lub raj piezometer rau kev ntsuas yooj yim.

Fig.6.Pressure ntsuas li

Thaum cov kua ntws tawm, lub piezometer tapping yuav tsum tsis pub tshaj 3 hli txoj kab uas hla thiab yuav tsum tau yaug nrog cov ciam teb nto. Rau qhov raug ntau dua, lub nplhaib piezometer yuav haum.Qhov no muaj ib lub voj voog nyob ib puag ncig cov yeeb nkab thiab txuas nrog nws los ntawm ntau qhov sib npaug sib npaug tappings.

Manometer

Manometer Lub hauv paus ntsiab lus yog tib yam li tau piav qhia saum toj no, tab sis cov teeb meem cuam tshuam nrog lub raj ntev ntev tau kov yeej los ntawm kev ua kom haum U-tube uas muaj cov kua dej tsis zoo. Mercury (qhov tshwj xeeb lub ntiajteb txawj nqus 13,6) yog cov kua manometer feem ntau ua haujlwm rau ntsuas dej siab. Lub ntsuas siab p hauv cov kav dej yog muab los ntawm

Qhov twg

h = qhov sib txawv ntawm qib ntawm cov kua manometer hauv ob ceg,

z = qhov siab ntawm cov yeeb nkab center kab saum toj no lub meniscus nyob rau hauv lub limb ntawm cov yeeb nkab sab, thiab

w, wm = qhov loj ntawm cov yeeb nkab thiab manometer kua feem.

tis mus rau qhov hloov pauv txoj haujlwm ntawm menisci, calibration ncaj qha tsis tuaj yeem ua tau. Txawm li cas los xij, qhov no yuav ua tiav yog tias cov ceg ntawm cov yeeb nkab sab yog loj heev kom cov qib ntawm cov meniscus tseem zoo li qub. Lub siab tuaj yeem raug nyeem tawm ntawm qhov kev kawm tiav uas txuas nrog rau lwm tus ceg.

Fua ig.7. Differential manometer

Kev ntsuam xyuas ntau ntawm cov yeeb nkab ntws feem ntau yog ua raws li kev ntsuas ntawm qhov sib txawv ntawm cov tapping nyob ze. Ib qho manometer sib txawv (Fig.7) yog ua haujlwm thiab cov kua manometer feem ntau yog mercury. Thaum qhov sib txawv ntawm qhov sib txawv me me, cov kua sib zog ua kom tsis muaj zog yuav ua rau cov txiaj ntsig zoo dua.

Lub siab sib txawv pt- pzis muab los ntawm

Cov manometers sib txawv ntawm qhov sib txawv ntau dua tau tsim los ua kom tau raws li cov kev xav tau tshwj xeeb ntawm kev lag luam thiab kev sim ua haujlwm.

Bpeb gauge

Qhov no yog cov cuab yeej lag luam uas haum ncaj qha rau cov yeeb nkab nws tus kheej lossis mus rau qhov kawg ntawm kab piezometer. Nws muaj ib tug bent raj tshem tawm dawb do nyob rau hauv lub nkhaus feem thiab tuav rigidly ntawm lub qia. Ib qho kev nce siab hauv siab zoo li ncaj rau lub raj thiab, raws li qhov deflection yog ncaj qha proportional rau lub siab thov, ib qho yooj yim mechanism ua rau yav tas los raug kaw ncaj qha. Txij li thaum lub siab nyob rau sab nraud ntawm lub raj yog atmospheric, lub ntsuas siab tau sau npe thiab qhov no feem ntau siv tau rau qhov chaw nruab nrab ntawm qhov ntsuas.

Bourdon gauge yog qhov tseem ceeb raws li qhov taw qhia dav dav ntawm lub siab tab sis tsis haum qhov twg xav tau ntau qhov tseeb, zoo li feem ntau yog cov teeb meem thaum ntsuas qhov sib txawv.

Vertical Turbine Hluav Taws Twj

Qauv No: XBC-VTP

XBC-VTP Series ntsug ntev ncej tua hluav taws twj tso kua mis yog series ntawm ib theem, multistage diffusers twj, tsim nyob rau hauv raws li qhov tseeb National Standard GB6245-2006. Peb kuj tau txhim kho tus qauv tsim nrog kev siv ntawm tus qauv ntawm United States Fire Protection Association. Nws yog tsuas yog siv rau cov dej tua hluav taws hauv petrochemical, natural gas, fais fab nroj tsuag, paj rwb textile, wharf, aviation, warehousing, high-rising building and other industries. Nws tseem tuaj yeem siv rau nkoj, dej hiav txwv tank, nkoj hluav taws thiab lwm yam khoom siv.
