Kuvandudzwa kwepombi dzesimbi nhema

Nzira yeWhitehouse yakakwenenzverwa naJohn Moon muna 1911. Tekinoroji yake inoita kuti vagadziri vagadzire kuyerera kwepombi. Akashandisa tekinoroji yake kugadzira michina uye zvirimwa zvakawanda zvekugadzira zvakazvigamuchira. Ipapo kwakauya kudiwa kwepombi dzesimbi dzisina musono. Machubhu asina musono akatanga kuumbwa nemaburi ekuchera pakati pehumburumbira. Nekudaro, zvinonetsa kudhiraivha nemazvo anodiwa kuti ive nechokwadi chekufanana kwemadziro. Kuvandudzwa kwa1888 kwakawedzera kugona nekukandira mabheti kumativi ezvidhinha zvisingadziviriri moto. Mushure mekutonhora, bvisa chidhinha, uchisiya gomba pakati.

Kushandiswa kwepombi yesimbi yakasviba

Kusimba kwepombi yesimbi nhema kunoita kuti ive yakanaka pakufambisa mvura uye gasi rechisikigo munzvimbo dzekumaruwa nemaguta, pamwe nekudzivirira tambo dzemagetsi nemakombi anotakura mhepo inotsikirira nemhepo. Pombi dzesimbi nhema dzinoshandiswa neindasitiri yemafuta nepetroleum kutakura mafuta akawanda kunzvimbo dziri kure. Izvi zvinobatsira nekuti pombi yesimbi nhema inoda kugadziridzwa kushoma. Zvimwe zvinoshandiswa papombi dzesimbi nhema dzinosanganisira kugovera gasi mukati nekunze kwemba, matsime uye masisitimu etsvina. Pombi dzesimbi nhema hadzimboshandiswi kutakura mvura yekunwa.

Kufambira mberi musainzi kwakavandudza zvikuru nzira yekugadzira pombi yakasungwa neWhitehouse. Nzira yake ichiri nzira yekutanga yekugadzira mapaipi, asi zvigadzirwa zvemazuva ano zvekugadzira zvinogona kuunza kupisa kwakanyanya uye kumanikidzika kunoita kuti kugadzira pombi kuve kwakanyanya. Zvichienderana nedhayamita yazvo, mamwe maitiro anogona kugadzira pombi yakakandwa pamwero unoshamisa wemamita 1,100 paminiti. Nekuwedzera kukuru kwehuwandu hwekugadzirwa kwepombi dzesimbi, kunaka kwechigadzirwa chekupedzisira kwakagadziridzwawo.

Kuvandudzwa kwezvigadzirwa zvemazuva ano zvekugadzira uye kugadzirwa kwezvigadzirwa zvemagetsi zvakakonzera kuvandudzwa kukuru mukushanda uye kutonga kwehutano. Vagadziri vemazuva ano vanoshandisa mageji eX-ray akakosha kuti ave nechokwadi chekufanana kwemadziro. Kusimba kwechubhu kunoedzwa nemuchina unozadza chubhu nemvura pasi pekumanikidzwa kwakanyanya kuti ive nechokwadi chekuti chubhu inobatwa panzvimbo. Mapombi akakundikana anoraswa.

Kushandiswa kukuru kwepombi yakabatiswa kutakura mvura kuenda kudzimba uye zvivakwa zvekutengesa. Zinc zvakare inodzivirira kuunganidzwa kwemamineral deposits anogona kuvhara pombi dzemvura. Mapaipi ane galvanized anowanzo shandiswa semafuremu echikafu nekuda kwekusaora kwawo.

pombi yesimbi yakasviba

Nyeredzi nhema pombi yakasiyana nenyere nekuti haina coating. Iyo yakasviba ruvara inobva kune iron oxide inoumba pamusoro payo panguva yekugadzira. Iko kushandiswa kukuru kwepipe dzesimbi nhema ndeyekutakura propane kana gasi rechisikiro kune zvivakwa zvekugara uye zvekutengesa. Iyo pombi inogadzirwa isina seams, zvichiita kuti ive nzira iri nani yekutakura magasi. Pombi yesimbi nhema inoshandiswawo mumasisitimu ekupfapfaidza moto nekuti inodzivirira moto kupfuura pombi yemarara.

Nhanganyaya kune Kusiyana

• Mapombi matema nemarata anogadzirwa nesimbi.
• Mapaipi ane galvanized ane zinc coating, nepo mapaipi matema haana
• Nemhaka yokuti iri nyore kuita ngura, pombi nhema dzakanyanya kukodzera kutakura gasi. Kune rumwe rutivi, mapaipi ane galvanized anonyanya kutakura mvura, asi kwete rombo
• Mapaipi ane galvanized anodhura nekuti ane zinc coating
• Galvanized pipe inogara yakasimba

Mvura uye gasi zvinofanirwa kupinzwa mupombi kune zvivakwa zvekugara uye zvekutengesa. Zvitofu zvemagetsi egasi, zvidziya zvemvura uye zvimwe midziyo, nepo mvura yakakosha kune zvimwe zvinodiwa nevanhu. Mhando mbiri dzepombi dzinonyanya kushandiswa kutakura mvura negasi pombi dzesimbi nhema uye mapaipi esimbi.

Dambudziko
Iyo zinc iri pamapombi ane galvanized inogona kupera nekufamba kwenguva, ichivhara mapaipi. Kuputika kunogona kuita kuti pombi iputika. Kushandiswa kwepombi dzemarara kutakura gasi kunogona kuva nengozi. Ukuwo, pombi dzesimbi nhema dzinoora zviri nyore kupfuura mapaipi ane marita uye dzinobvumira zvicherwa zvinobva mumvura kuungana madziri.

Mutengo
Mapombi esimbi ane galvanized anodhura kupfuura pombi dzesimbi nhema nekuti kugadzira mapaipi anonatsiridza kunosanganisira kuita galvanizing uye kugadzira. Magalvanized fittings anodhurawo kudarika ayo anoshandiswa pasimbi nhema. Mapaipi esimbi ane galvanized haafanire kubatanidzwa kune nhema simbi pombi panguva yekuvakwa kwezvivakwa zvekugara kana zvekutengesa.

• ASTM A53 ndeye yakajairwa kutsanangurwa kwepombi, simbi, nhema uye inopisa yakanyikwa, yakabatiswa, yakasungwa, uye isina musono.
• ASTM A106 ndiyo yakajairwa yekumisikidza isina musono kabhoni simbi pombi yeyakanyanya tembiricha sevhisi.

inogona kunge yakasungwa kana kuti isina musono, zvichienderana nekuti yakatengwa sei. Iyo yakajairika simbi pombi yakatarwa, kusanganisira galvanized pombi uye nhema pombi.
A106 ikemikari yakafanana nepombi asi yekupisa tembiricha sevhisi (kusvika 750 madhigirii Fahrenheit). Ichubhu isina musono.
MuUS zvirinani, pombi yakasungwa kazhinji ine A53, nepo A106 isina musono. Kana iwe ukakumbira A53 kuUS, ivo vanozotaura A106 seimwe nzira.
Kuumbwa Kwemakemikari
Semuenzaniso, kana tichienzanisa A106-B uye A53-B isina musono kubva kune kemikari kuumbwa maonero, tinowana:

• 1. A106-B ine silicon, shoma. 0.10%, iyo A53-B iri 0%, silicon chinhu chakakosha chekuvandudza chiyero chekupisa.
• 2. A106-B ine manganese 0.29-1.06%, iyo A53-B iri 1.2%.
• 3. A106-B ine sarufa yakaderera uye phosphorus, max. 0.035%, iyo A53-B ine 0.05 uye 0.045%, zvichiteerana.
