    Pombi Yemvura Yepamusoro Inoshanda Zvikuru

    Pombi Yemvura Huru Inoshanda Zvakawanda Mufananidzo Wakaratidzwa
    • Pombi Yemvura Yepamusoro Inoshanda Zvikuru

    Tsananguro pfupi:

    Migero yedu yemvura yakagadzirwa kuti ishande zvakanaka uye ishande zvakasiyana-siyana, uye inogona kushandiswa munzvimbo dzakasiyana-siyana, zvichiita kuti ive yakakodzera kune vanogadzira makambani, madhorobha, uye maindasitiri.

    Nhanganyaya yeChigadzirwa

    Tichiunza mapaipi edu makuru emvura anokwanisa kushanda zvakanaka, akagadzirirwa kusangana nezvinodiwa zvakasiyana-siyana zvemaindasitiri akasiyana-siyana. Kambani yedu yakagadzirwa mufekitori yedu yemazuva ano muCangzhou, Hebei Province, yave iri kutungamira mukugadzira mapaipi kubvira payakatangwa muna 1993. Nenzvimbo ye350,000 square metres uye pfuma yese yeRMB 680 miriyoni, tinodada nekuva nevashandi vakazvipira ve680 vane hunyanzvi.

    Yedupombi huru yemvuradzakagadzirirwa kushanda zvakanaka mumabasa akakosha akadai semapombi emvura nemigero yegesi. Tinonzwisisa kuti zvinodiwa zvemapaipi aya, kusanganisira ma welds nemagadzirirwo espiral seam, zvine basa guru mukushanda kwawo uye kuvimbika. Ndosaka tichishandisa matekiniki ekugadzira epamusoro uye matanho akasimba ekudzora mhando kuti tive nechokwadi chekuti mapaipi edu anosangana nezvinodiwa zvepamusoro zveindasitiri.

    Mapombi edu emvura akagadzirwa kuti ashande zvakanaka uye ashande zvakasiyana-siyana, uye anogona kushandiswa munzvimbo dzakasiyana-siyana, zvichiita kuti akwanise kushandiswa nevanoita mabasa ekuvaka, madhorobha, uye maindasitiri. Ungave uri kuisa pombi itsva yemvura kana kuvandudza tambo yegesi iripo, mapaipi edu anopa kugara kwenguva refu uye simba rinodiwa kuti akwanise kusangana nezvinodiwa zvechero chirongwa.

    Kubatsira Kwechigadzirwa

    Chimwe chezvakanakira zvikuru zvemapaipi makuru emvura ndechekuti anoshandiswa zvakanyanya. Akagadzirwa kuti akwane zvinodiwa munzvimbo dzakasiyana-siyana, zvichiita kuti akwanise kushandiswa munzvimbo dzemaguta nedzekumaruwa. Kushanduka-shanduka kwemapaipi aya kunoita kuti ashandiswe mumabasa akasiyana-siyana, kubva pakupa mvura mudzimba kusvika pakufambisa gasi mumaindasitiri. Kushanduka-shanduka uku kwakakosha kumakanzuru nemabhizinesi, sezvo zvichiita kuti nzira dzekutenga nekuisa dzive nyore.

    Kushaikwa kwechigadzirwa

    Kushanda kwemapaipi aya kunogona kuchinjwa nezvinhu zvakaita semamiriro evhu, kushanduka-shanduka kwetembiricha, uye mwero wekumanikidzwa. Semuenzaniso, mapaipi akasungirirwa anogona kunge ari nyore kukuvadzwa nengura mune dzimwe nzvimbo, nepo mapaipi emusono akasimba anogona kunge asina kusimba zvakanyanya mumamiriro ekumanikidzwa kwakanyanya. Kunzwisisa zvipingamupinyi izvi kwakakosha kune mainjiniya nevarongi kuti vave nechokwadi chekuti mhando chaiyo yemapaipi inosarudzwa pakushandisa kwega kwega.

    Kushandiswa

    Kukosha kwemapombi emvura akavimbika uye emhando yepamusoro mukuvandudza zvivakwa zvinoramba zvichikura hakugone kupfuudzwa zvakanyanya. Mapombi aya anozivikanwa nekugona kwawo kushanda zvakanaka, akakosha mukushandiswa kwakasiyana-siyana, kusanganisira mapaipi emvura negasi. Maitiro awo, akadai sewelds uye dhizaini yespiral seam, anoita basa guru mukuona kuti anoshanda zvakanaka uye hupenyu hwebasa.

    Mapombi edu makuru emvura anoshandiswa mumabasa akasiyana-siyana, izvo zvinoratidzwa muminda yakasiyana-siyana. Ingava sisitimu yemvura yemuguta kana network yekugovera gasi, mapaipi edu anogona kutsungirira kuomarara kwekushandiswa kwezuva nezuva uku achichengetedza kushanda zvakanaka. Akasungirirwa uyepombi yemusono inotendererasarudzo dzinopa mukana wekushandiswa, zvichibvumira mhinduro kuti dzigadziriswe kuti dzienderane nezvinodiwa zvepurojekiti.

    Mibvunzo Inowanzo bvunzwa

    Mubvunzo 1. Pombi huru yemvura inogadzirwa nezvinhu zvipi?

    Midziyo mikuru yemvura inowanzogadzirwa nezvinhu zvinogara kwenguva refu zvakaita sesimbi, PVC neHDPE. Sarudzo yezvinhu zvinoenderana nekushandiswa kwacho uye mamiriro ekunze.

    Mubvunzo wechipiri. Chii chinonzi mapaipi akasungirirwa uye mapaipi emusono anotenderera?

    Pombi yakasungirirwa inoumbwa nekubatanidza mipendero miviri yepombi pamwe chete, iyo ine chimiro chakasimba uye chisingadonhedze mvura. Pombi yemusono inotenderera inoumbwa nekumonera simbi yakati sandara kuita sechubhu, iyo ine kuchinjika kukuru mukugadzirwa uye kushandiswa.

    Mubvunzo 3. Ndingasarudza sei pombi yakakodzera yepurojekiti yangu?

    Funga nezvezvinhu zvakaita serudzi rwemvura iri kutumirwa, zvinodiwa pakumanikidzwa, uye mamiriro ekunze. Kubvunza nyanzvi kunogonawo kubatsira kuona kuti unosarudza pombi yakanakira zvaunoda.
