Adapter Wells - Niaj hnub nimno zoo tiav txoj kev

Workers dej rau koj lub teb chaws qhov chaw, muaj kev los daws tau ib tug ntau ntawm cov lus nug. Piv txwv li, yuav ua li cas zoo drilled li muab ib tug kaw qhov nyob rau hauv lub sidebar, xaiv ib tug zoo twj tso kua mis thiab ntau npaum li cas. Nyob rau hauv cov khw lub qhov muag diverge los ntawm lub nplua mais ntawm downhole khoom. Yog hais tias peb tham txog cov kev ntseeg ntawm cov zoo khi-nyob rau hauv, tab sis tam sim no muaj cov plaub yooj yim cawm: ib tug zoo, ib tug pavilion, ib tug caisson rau qhov dej thiab cov qhov dej adapter. Lawv txawv los ntawm txhua lwm yam los ntawm tus nqi, uas muaj kev ua hauj lwm thiab kev cia siab. Yuav pib, muab pov tseg ua ntej ob txoj kev rau lub hom phiaj vim li cas (qhov dej - yog heev unreliable, thiab pavilions nqi yog li ntawd siab hais tias lawv yog tsuas yog siv nyob rau hauv lub koom haum ntawm collective dej). Yog li ntawd, nyob rau hauv no tsab xov xwm peb yuav tsom ntsoov rau cov ob nrov tshaj plaws txoj kev kho ntawm cov dej qhov dej: caissons thiab borehole adapters.

Caisson yog ib tug loj chim ua los ntawm yas los yog hlau, uas muaj ib lub qhov nyob rau hauv qab (mus nkag rau lub casing ntawm lub zoo), thiab ib lub qhov uas muaj ib tug manhole nyob rau sab saum toj.

Rau ib ntev lub sij hawm hlau caissons rau lub qhov dej yog ib tug monopolist nyob rau hauv lub mov kho lub teb chaws. Cov khoom muaj ib tug xov tooj ntawm drawbacks: nqi siab, complexity ntawm installation, impressive qhov ntev thiab luj, lub dubious aesthetic nqi, cov neeg pluag tiv thaiv txhaum kev txhaum cai qhib. Tab sis lub ntsiab drawback - nws yog yuav luag tiav helplessness tiv thaiv corrosion. Tom qab ntawd tuaj lub yas caissons, nyob rau hauv uas muaj yog ib tug tseem ceeb kom zoo dua li hlau caissons: Yas tsis xeb. Tiam sis hmoov tsis tsis muaj disadvantages: tshiab caissons muaj heev me ntsis tsis kam mus av siab. Qhov no disadvantage yog predestined tsis muaj peev xwm rau nruab yas caissons qhov twg lub nqhuab theem siab txaus.

Tu siab los yog tsis, txhua txhua yam hais txog yog hais tias lub sij hawm ntawm kim tua caissons tuaj mus rau qhov kawg - qhia tawm rau ntawm competing muaj lawv ntau npaum thiab compact kwv tij txheeb ze nrog txhua dua hnub nws yuav ntau thiab ntau dua. Hais txog seb nws yog ib qhov zoo los yog phem, nws yuav ua tau ib tug ntev heev lub sij hawm mus hais lus cam, tab sis cov kev muaj tiag yog tias tau txais kev pab yog nce siab nyob rau hauv cov lus teb rau lo lus nug "yog dab tsi zoo dua yuav ib tug adapter rau hauv lub qhov."

Adapters rau qhov dej (Eng. Pitless adapter) nyob rau kuj ntev los no, nyob rau hauv lub 60s ntawm lub xeem caug xyoo, tiam sis tsuas yog nyob rau hauv nruab nrab-80s, lawv tau tau koob meej ntawm tau txais kev pab. Pitless-adapters yog cov ntsaws ruaj ruaj dej siab kav, ua los ntawm cov bronze los yog dag.

Yog hais tias koj xav mus yuav cov zoo adapter, koj yuav tsum tau paub txog qhov sib txawv ntawm bronze thiab tooj dag fittings. Toog thiab bronze alloys yog tooj liab hom uas siv sib txawv alloying Cheebtsam. Toog yog doped siv zinc, thaum lub sij hawm bronze - sib txawv co tsuas yog zinc thiab npib tsib xee. Bronze tshaj dag rau xeb kuj ntawm lub cov neeg kho tshuab thiab anti-kev sib txhuam zog. Bronze yog ruaj khov nyob rau hauv huab cua, hiav txwv dej, carbonic acid tshuaj thiab cov kev daws ntawm feem ntau organic acids. Raws li ib tug tsim nyog tau, nyob rau hauv lub Bronze adapter tsis nyuaj siab xeb cracking yuav tshwm sim. Nws yuav tsis leach zinc. Tsis txhob yuav nyob rau hauv cov dej system ntawm hnyav hlau xws li npib tsib xee thiab cov hlau lead. Tsis tas li ntawd peb yuav tsum tsis txhob hnov qab hais tias ib tug bronze separator ntawm ob tug sib txawv cov ntaub ntawv yuav pab tiv thaiv tau tus phenomenon ntawm galvanic corrosion. Lub tsuas drawback ntawm bronze wares nyob rau hauv pem hauv ntej ntawm lub dag yog lawv nqi. Qhov no yog vim muaj ib tug ntau dua cov ntsiab lus ntawm tooj liab nyob rau hauv lub bronze.

Ntsiab lus, peb yuav hais tias kom tau raws li lub hygienic yuav tsum tau, cov qauv ntawm kev ntseeg tau thiab durability tsis muaj kev siv ntawm bronze borehole adapters yog yooj yim ua.
