Kuyambitsa Zoyambitsa

Kuyambitsa Utumiki Wathu Kwambiri Mapaipi A Main, adapangidwa kuti akwaniritse zosowa zosiyanasiyana za mafakitale osiyanasiyana. Zopangidwa mu fakitale yathu yaukadaulo ku Cangzhou, kafukufuku wa Hebei, kampani yathu yakhala mtsogoleri wopanga chitumbuwa kuyambira 1953. Ndi malo a mita 350,000, ife amanyadira kukhala ndi ogwira ntchito odzipereka a akatswiri 680 aluso.

Zathuchitoliro chachikulu chamadziAmakhala opangidwa kuti azichita bwino kwambiri pamapulogalamu ofunikira monga maina amadzi ndi mizere yamagesi. Tikumvetsetsa kuti mapangidwe awa, kuphatikiza ma weldes ndi masikono owoneka bwino, amagwira ntchito yovuta kwambiri mwaukadaulo wawo komanso kudalirika. Ichi ndichifukwa chake timagwiritsa ntchito njira zapamwamba zopangira kupanga ndi njira zazikulu zowongolera kuti mapaipi athu azikhala ndi miyezo yapamwamba kwambiri.

Magulu athu amadzi adapangidwa kuti azigwira ntchito mosiyanasiyana komanso mosiyanasiyana, ndipo angagwiritsidwe ntchito m'malo osiyanasiyana, kuwapangitsa kukhala abwino kwa makontrakita, maboma, komanso kugwiritsa ntchito mafakitale. Kaya mukukhazikitsa madzi atsopano kapena kukweza mzere wamafuta omwe alipo, mapaipi athu amathandizira kulimba mtima komanso mphamvu zofunika kukwaniritsa zofuna za ntchito iliyonse.

Phindu lazinthu

Chimodzi mwazabwino za mapaipi amadzi ndi ntchito yawo yayitali. Adapangidwa kuti akwaniritse zofuna za malo osiyanasiyana, ndikuwapangitsa kukhala oyenera kuti akhale oyenera ku madera onse a ukadaulo komanso kumidzi. Kusintha kwa mapaipi awa kumawalola kugwiritsidwa ntchito mu mapulogalamu osiyanasiyana, kuchokera ku madzi ogona kumayendedwe ogulitsa mafakitale. Kusintha kumeneku kuli kofunikira kwa maboma ndi mabizinesi ofanana, monga momwe zimathandizira kugula ndi njira zosinthira.

Kuperewera

Kuchita kwamapaipi awa kumatha kukhudzidwa ndi zinthu monga dothi, kusinthasintha kwa kutentha, komanso magawo okakamizidwa. Mwachitsanzo, mapaipi otwala amatha kutengeka kwambiri ndi kutukuka m'maiko ena, pomwe mapaipi osokosera sangakhale owawa kwambiri. Kuzindikira izi pali zofunika kwa opanga ndi okonza mapulogalamu amtundu woyenera amasankhidwa kuti azigwiritsa ntchito iliyonse.

Karata yanchito

Kufunika kwa madzi odalirika, mabungwe apamwamba kwambiri pakukula kwa zomangamanga zomwe zikuchitikapo sikungafanane. Amadziwika kuti ndi kuchuluka kwawo, ziphuphu izi ndizofunikira pakugwiritsa ntchito mitundu mitundu, kuphatikizapo mapaipi a madzi ndi mafuta. Maudindo awo, monga ma welds ndi sturus stumation, amatenga mbali yofunika kwambiri pakuwonetsetsa zoyenera ndi moyo wa ntchito.

Mapaipi athu akuluakulu amagwiritsidwa ntchito pamapulogalamu osiyanasiyana, omwe amawonetsedwa m'minda yambiri. Kaya ndi njira yamagetsi yamadzi kapena maofesi ogawa mpweya, mapaipi athu amatha kupirira ziwopsezo za kugwiritsa ntchito tsiku ndi tsiku ndikukhalabe bwino. Womenzedwa ndichitoliro cha spiruZosankha zimapereka kusinthasintha mu pulogalamu, kulola mayankho kuti achitidwe kuti akwaniritse zofunika polojekiti.

FAQ

Q1. Kodi chitoliro chachikulu chimapangidwa ndi chiyani?

Makuru amadzi nthawi zambiri amapangidwa ndi zida zokhazikika monga chitsulo, pvc ndi hdpe. Kusankhidwa kwa zinthu kumatengera ntchito inayake komanso nyengo.

Q2. Kodi mapaipi owonda ndi mipata yanji?

Chitoliro chowala chimapangidwa ndi kulowa m'mphepete mwa chitoliro limodzi, chomwe chili ndi mawonekedwe olimba komanso otulutsa. Chitoliro cha spirury chimapangidwa ndi kugubuduza ka chitsulo chowoneka bwino mu chubu, chomwe chimasinthasintha kwambiri pakupanga ndi kugwiritsa ntchito.

Q3. Kodi ndingasankhe bwanji mapaipi oyenera kuti ndilingalire ntchito yanga?

Onani zinthu monga mtundu wamadzi omwe amaperekedwa, zofuna kutengera kutengera kutengera kutengera kutengera kutengera zachilengedwe. Kufunsira ndi katswiri kungathandizenso kuonetsetsa kuti mungasankhe bwino kwambiri pazosowa zanu.
