Mapaipi apamwamba kwambiri ogulitsa

Kufotokozera kwaifupi:

Mapazi athu owoneka bwino a kaboni pazipilala za kaboni yamiyala yapangidwa kuti apirire malo ovuta, ndikuwonetsetsa kudalirika komanso moyo wautali. Kaya mukufuna mapaipi a malo opangira, kugwiritsa ntchito mphamvu kapena kugwiritsa ntchito kwina kulikonse kwa mafakitale, malonda athu amapangidwa kuti apereke magwiridwe antchito kwambiri.

Tumizani imelo kwa ife

Tsatanetsatane wazogulitsa

Matamba a malonda

Mapaipi athu amapangidwa pogudubuza chitsulo chotsika-kaboni zilembo za chubu chotsitsimutsa, kenako ndi nyongolotsi yowuma kuonetsetsa kuti kukhulupirika ndi kukhazikika kwa seams. Njira yopanga yopangayi yopanga imatipatsa mapaipi akuluakulu omwe siabwino komanso osinthasintha, zimapangitsa kuti akhale abwino kugwiritsa ntchito osiyanasiyana pomanga mafuta ndi mayendedwe a mpweya.

Fakitale yathu ili mumtima wa Cangzhou City, Dera m'chigawo cha Hebei ndipo wakhala mtsogoleri wazipasumbu wachitsulo kuyambira kukhazikitsidwa kwake mu 1953. Makina aluso ndi makina, zomwe zimatithandiza kupanga mapaipi apamwamba kwambiri omwe amakumana ndi miyezo yapadziko lonse. Ndi zinthu zonse za RM 680 miliyoni ndi antchito odzipereka a 680 odzipereka, timadzinyadira kudzipereka kwathu ku ntchito yabwino komanso kukhutitsidwa kwamakasitomala.

Mayeso a Hydrostatic

Kufotokozera Za Zogulitsa

Chitolirochi chizipirira mayesedwe a hydrostatic popanda kutaya msoko kapena chipika
Ojowina sayenera kusinthidwa, pokhapokha ngati magawo a chitoliro omwe amagwiritsidwa ntchito polemba zolemberawo adayesedwa bwino kwambiri asanafike.

Phindu lazinthu

1. Chimodzi mwazikhalidwe zazikulu za mapaipi athu achitsulo ndi kuthekera kopanga mapaipi asanu ndi awiri. Izi zimatheka kudzera mu chinthu china chopanga chomwe chimaphatikizapo kusungunuka kofatsa m'matumba a chubu pamalo ena a herdical kenako ndikulowetsa seams.

2. Njira imeneyi siyikuwonjezera mphamvu ndi kukhazikika kwa chitoliro, komanso limaperekanso kusinthasintha pakupanga ndi kugwiritsa ntchito.

3. Mapaipi athu akuwononga ndipo amatha kupirira zovuta zambiri, zimapangitsa kuti akhale abwino kwa mafakitale osiyanasiyana kuphatikizapo mafuta ndi mpweya, kupezeka kwamadzi, ndi zomanga.

Kuperewera

1. Njira yopanga, ngakhale yothandiza, imatha kubweretsa kusiyanasiyana ngati sikunayang'anire mosamalitsa.

2. Mtengo woyamba wachitoliro chachitsuloZitha kukhala zapamwamba kuposa njira zina zochepetsetsa, zomwe zingaganize ntchito zamalonda.

3.Komwe matope athu adapangidwa kuti akhale olimba, angafunikire kukonza pafupipafupi kuti akwaniritse moyo wambiri, makamaka m'malo osokoneza bongo.

Msika

Misika yathu yofunika imafalikira kumadera osiyanasiyana, kuonetsetsa kuti titha kukwaniritsa zosowa za makasitomala athu padziko lonse lapansi. Tikunyadira kupereka mapaipi apamwamba kwambiri omwe samangokumana komanso kuposa malamulo ogulitsa. Kudzipereka kwathu kwa ulamuliro wabwino komanso kukhutitsidwa kwa makasitomala kwatipatsa mbiri yabwino yogulitsa wodalirika ku mafakitale achitsulo.
