Kugwiritsiridwa ntchito kwa zida zodziŵika bwino, zokhazikitsidwa ndi zosungidwa zotetezera kubwerera kumbuyo kungapewe ngozi ya zochitika zomwe zimayambitsidwa ndi anti-siphon ndi kupanikizika kumbuyo.
Kubwerera m'mbuyo kukupitiriza kuopseza kwambiri madzi athu abwino. Chifukwa cha kugwirizana pakati pa madzi akumwa ndi gwero lomwe likuganiziridwa kuti lili ndi madzi ogwiritsidwa ntchito, madzi a m'mafakitale, gasi, kapena zinthu zina zowononga, zochitika zobwerera m'mbuyo zimakhala zovuta kuzizindikira pokhapokha ngati pali zolakwika ndi zizindikiro zomwe zingakhale zoopsa. Kugwiritsiridwa ntchito kwa zida zodziŵika bwino, zokhazikitsidwa ndi zosungidwa zotetezera kubwerera kumbuyo kungapewe ngozi ya zochitika zomwe zimayambitsidwa ndi anti-siphon ndi kupanikizika kumbuyo.
Kutchula njira yoyenera yobwereranso kumadalira kugwiritsa ntchito. Ndikofunikira kudziwa zolakwika zomwe zingachitike pamapangidwe a mapaipi omwe alipo. Zotsatirazi ndi mfundo 10 pofotokoza.
Pankhani yochepetsera kutayika kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. Ngati kutayika kwamphamvu kuli kwakukulu kwambiri kuti dongosololi lipereke mphamvu zokwanira pazigawo zake, zikhoza kutanthauza kuti pampu yowonjezera iyenera kuwonjezeredwa kapena chitoliro chokulirapo chiyenera kugwiritsidwa ntchito, zomwe zidzawonjezera ndalama zambiri. Ngakhale kutaya mphamvu ndi gawo lodetsa nkhawa pamakina onse, ndikofunikira kwambiri pamakina oteteza moto.
Onse opanga reflow amasindikiza ma curve othamanga / oyenda pazida zawo. Poyerekeza ma curve oyenda, onetsetsani kuti onse akuwonetsa momwe zinthu zilili - chifukwa kuchuluka kwa ma curve ndi kutsika kwapakati nthawi zambiri kumakhala kosiyana kwambiri.
Chiwopsezo chonse chazomwe zimafunikira pamakina operekera madzi amawerengedwera ndikuwonjezera kuchuluka komwe kukudziwika kwa zida zonse mudongosolo. Makhalidwe otaya a chipangizo chobwezera amatha kukhudza mwachindunji kayendedwe ka madzi akumwa a nyumbayo kapena makina opopera moto. Mukamapanga, chonde tcherani khutu ku zofunikira zoyendetsera nyumba.
Pamlingo wapamwamba kwambiri wogwiritsiridwa ntchito wamba, simukufuna kupitilira kuchuluka kwamayendedwe oyezera, pamwamba pake mudzawona kuwonjezeka kwakukulu kwa kung'ambika. Pazida zozimitsa moto, kuchuluka kwa moto wathunthu sikuyenera kupitilira kuchuluka kwa UL kwa valve.
Ngakhale kuyesayesa kwabwino, ntchito yanthawi zonse komanso magwero akunja osapeŵeka (monga zinyalala zochulukirapo m'madzi) zitha kupangitsa kuti woletsa kubwerera kumbuyo avale. Woletsa kubwerera m'mbuyo amafunikira kusamalidwa, zomwe ziyenera kuchitidwa ndi plumber waluso.
Pali zinthu zambiri zomwe muyenera kuziganizira posankha cholepheretsa kubwereranso: Ndikosavuta bwanji kupeza zigawo zamkati? Kodi magawowa angakonzedwe padera? Kodi amapezeka nthawi iliyonse? Kodi zinthu monga valavu yopumira kapena valavu yotseka zingachotsedwe kuti zikonzedwe kapena kusinthidwa? Kukonzekera kumakhala kovuta kwambiri komanso kumatenga nthawi yayitali, ndiye kuti mtengo wokonzanso umakwera.
Mikhalidwe yogwiritsira ntchito idzakhudza kwambiri mapangidwe, kukhazikitsa ndi bajeti ya dongosolo. Akuluakulu am'deralo ali ndi ulamuliro pa mitundu ya ma valve omwe amagwiritsidwa ntchito pamtundu uliwonse wa ntchito. Kutalika konse kwa valavu kumatha kupezeka muzolemba zaukadaulo zomwe zimaperekedwa ndi wopanga, zomwe ndizofunikira pakuchotsa pulogalamu yomwe ilipo. Ngati danga lili pamtengo wapatali, lingakhudzenso kukhazikitsa kwatsopano.
Kodi chipangizochi chidzakhala malo otani? Mwachitsanzo, zigawo za decompression zone sizingagwiritsidwe ntchito m'matangi kapena maenje apansi panthaka chifukwa zitha kumizidwa. Ganiziraninso za nyengo yomwe valavu idzawonekere komanso momwe idzakhudzire zigawo zomwe zikuwonekera.
Cholemetsa cha kusankha kwa zida makamaka mtengo wantchito wokhudzana ndi kusamalira ndi kukhazikitsa. Kuphatikiza apo, chonde ganizirani zomwe imapangidwa. Zipangizo zophatikizika ndi zitsulo zosapanga dzimbiri nthawi zambiri zimakhala zopepuka kuposa chitsulo chopangidwa ndi chitsulo kapena chitsulo. Zing'onozing'ono zimakhala bwino, chifukwa zimatha kusiya malo owonjezera a ma valve omwe amafunikira kwambiri mu dongosolo ndi kutenga malo ochepa mu chipinda cha makina.
Zida zopewera kubweza kumbuyo zimayikidwa m'malo osiyanasiyana, kuyambira malo otseguka mpaka zipinda zazing'ono zamakompyuta. Amapangidwa kuti azilola masinthidwe angapo oyika, kupangitsa mainjiniya opangira kupanga kukhazikitsa zida mumlengalenga. Zosankha zokwera ndizopingasa [zambiri], zoyimirira, mtundu wa "N" ndi mtundu wa "Z".
Nthawi zambiri, ntchito ya valve imakhala yosasinthika malinga ndi kasinthidwe kake; komabe, nthawi zonse muyenera kuwerenga zambiri zaukadaulo wa wopanga ndikufunsana ndi woyang'anira malamulo am'deralo musanapange chisankho.
Njira yoyesera valavu imadalira zofunikira za dipatimenti yamadzi am'deralo, koma valavu yokha idzakhudza zovuta za kuyesa valve ndi kuthetsa mavuto. Woyesa ayenera kugwiritsa ntchito tambala woyesa kuti ayese bwino ntchito ya zida. Ngati valavu ili ndi chilolezo chokwanira kumbali zonse, izi nthawi zambiri sizikhala vuto, koma ngati izi sizingatheke (kuphwanya malingaliro a wopanga) kapena pamene valve ikusinthidwa, khoma kapena mapaipi omwe alipo angapangitse kukhala kovuta kapena kosatheka kulowa Mayeso. tambala-izi zipangitsa kuti paipi ibwerenso kapena kusintha valavu kwathunthu.
Kuwonjezera pa kuyesa valavu, ntchito imodzi ya tambala yoyesera ndiyo kuthamangitsa valavu pofuna kuyesa kuchotsa zinyalala zomwe zingasokoneze kuyang'anitsitsa. Tambala wamkulu woyesera adzalola kuyenda kwambiri, motero kumawonjezera mwayi wanu wochotsa zinyalala. Pofuna kuyesa ndi kuthetsa vuto la valve, ndikofunika kuti valavu yotsekera pansi pamtsinje ikhale yotsekedwa mwamphamvu komanso yopanda kutulutsa. Pachifukwa ichi, kutsekedwa kwapamwamba ndi gawo lofunika kwambiri la zigawo zobwereranso, ndipo kuthekera kokonzanso kuti valavu iyesedwe kachiwiri ndiyofunikanso.
Pofotokozera cholepheretsa kubwerera, pali njira zambiri zotsekera zotsekera zomwe zilipo, kuphatikizapo: Ma valve a mpira - omwe amagwiritsidwa ntchito pamagulu a 2-inch. Ndipo imalola kutsegula kapena kutseka kosavuta kwa zida ¼; valavu ya butterfly-pamene kupotoza kwakufupi kumafunika, kumatha kutsekedwa pang'onopang'ono ndi ntchito ya gear kuti mupewe nyundo yamadzi (chofunikira pa chitetezo cha moto), kapena kulamulira kwamagetsi; NRS [tsinde losasunthika] Chipata cha valve-chabwino pamene mulibe kusiyana pamwamba pa gudumu lamanja ndipo simukusowa chisonyezero chowonekera cha malo (kutsegula / kutseka); OSY [tsinde lakunja ndi goli] valavu yachipata-masinthidwe okhazikika a mavavu amoto atali-m'mimba mwake, chifukwa tsinde la valavu lokwera limapereka chiwonetsero cha malo ndipo imatha kukhazikitsidwa ndi chosinthira; PIV [Column Indicator Valve] -kawirikawiri njira yopangira ma valve a zipata za NRS, mavavuwa amapangidwa kuti alumikizike ndi gawo lomwe liziwonetsa m'maso ""Otsegula" kapena "otsekedwa" ndipo nthawi zambiri amagwiritsidwa ntchito pamakina oteteza moto pomwe valavu ilibe. zofikirika, monga mobisa kapena kuseri kwa khoma.
Ndikofunikira kumvetsetsa malamulo amdera lanu ndi zomwe mukufuna, chifukwa chipangizocho chitha kuloledwa kugwiritsidwa ntchito mdera limodzi, koma chikuwoneka kuti sichikwanira mdera lina. Ndibwino kuti mukhalebe paubwenzi ndi woyang'anira mapaipi am'deralo ndi dipatimenti ya madzi kuti mupewe kulephera kwa kuyendera kapena kukhazikitsa zipangizo zodula kwambiri pamene zipangizo zowononga ndalama zikukwaniritsa zofunikira.

Okonza mapaipi, makontrakitala, ndi mainjiniya ali ndi njira zambiri zodziwira, kukonza ndi kupewa ziwopsezo zobwerera m'mbuyo zisanachitike, koma kusintha mawonekedwe a mapaipi ndi makina ovuta a mapaipi kumapangitsa kuti zikhale zovuta kuyenda.
