Mapaipi a Goolow-Seapect of Mobisa Founa Lalikulu

Mapaipi a Goolow-Seapector a pansi panthaka

Kufotokozera kwaifupi:

Pokhazikitsa matumbo apansi panthaka lachilengedwe, kusankha kwa zinthu ndi kofunikira kwambiri kuti muwonetsetse chitetezo ndi kuchita bwino kwa zomangamanga. Gawo la Holloloolod Surctional Machubu a arc, akuwoneka bwino kwambiri chifukwa cha mphamvu zawo zazikulu, kukhazikika komanso kukana kuwonongeka. Mu blog iyi, tiona kufunika kwa mbiya-Gawo la kapangidwe kapangidwe kakumanga kwa pansi pa mapipu a mpweya wobisika ndi zabwino zomwe amapereka.

Tumizani imelo kwa ife

Tsatanetsatane wazogulitsa

Matamba a malonda

Arc yokhazikikamkatesamagwiritsidwa ntchito kwambiri pantchito yomanga mizere yobisika yamagesi chifukwa cha kupanga kwawo kwapadera. Mapaipi amapangidwa ndi kupanga zitsulo zokhala ndi chitsulo chotentha mu mawonekedwe a kuzungulira kenako kuwawalitsa pogwiritsa ntchito njira yotentha. Izi zimapanga mapaipi a Hurc-Hurmer Arc omwe ali ndi makulidwe ofanana ndi kulondola bwino kwambiri, ndikuwapangitsa kukhala abwino pagalimoto yamagesi.

Limodzi mwa maubwino akuluakulu a m'chimanda cha Howlow-sepict ndi kukana kwawo kovunda. Ataikidwa m'manda mobisa, mapiyo achilengedwe amawonekera ndi chinyezi, mankhwala a dothi komanso zinthu zina zodula. Mapaiwo a Arc amagwera amapangidwa makamaka kuti apirire pansi paukadaulo mwankhanza izi, kuonetsetsa kukhala ndi moyo wokhalitsa komanso kudalirika kwa mapaipi achilengedwe.

Kuphatikiza pa kukana kwa chimbudzi,Mapaipi a Goolow-SeaPatsani mphamvu zazikulu ndi kukhazikika, kuwapangitsa kukhala oyenera kukhazikitsa pansi panthaka. Kupanga kwapakatikati pa mapaipi awa kumapereka mwayi wabwino kwambiri wonyamula katundu komanso kuwaloleza kulemera kwa nthaka ndi mphamvu zina zakunja popanda kunyalanyaza zinthu zawo. Izi ndizofunikira makamaka m'malo ovuta, pomwe mapaipi amayenera kuyang'anizana ndi gulu lapansi ndi malo okhalamo.

Kuphatikiza apo, mapaipi okhala ndi kapangidwe kake amadziwika chifukwa chogwiritsa ntchito bwino zinthu komanso kugwiritsa ntchito mtengo. Amabwera m'mitundu yambiri ndi makulidwe ndipo amatha kusinthidwa kuti akwaniritse zofunikira zina za pobisalira masitepe a gasi yamagesi. Izi zimachepetsa kufunikira kwa zowonjezera zowonjezera ndi kuwotcherera, zomwe zimapangitsa kukhazikitsa mwachangu ndikuchepetsa ndalama zonse. Kupepuka kwa mapaipi awa kumapangitsanso mayendedwe ndikuthana ndi kugwiritsa ntchito bwino, amaperekanso ndalama zothandizira kusungidwa.

Pankhani ya chitetezo ndi mphamvu yaPansi pa Magesi a Magesi, kusankha kwa zinthu ndi kofunikira. Mapazi a Goolow-Seaffic Mapictaged Mapaipi a Arc, kuphatikiza mphamvu, kukhazikika, kukhazikika kwa kuchuluka kwa kuchuluka kwa mtengo wake, kumapangitsa kuti akhale abwino potumiza mankhwala osokoneza bongo. Mwa kuyika ndalama m'mapaipi apamwamba kwambiri omwe amapangidwa mobisa, makampani ogulitsa amatha kutsimikizira kudalirika komanso kukhazikika kwa malo awo pokonzanso ndikukonzanso mtengo nthawi yayitali.

Mwachidule, gawo la gawo la Hollololot pamtanda limakhala gawo lofunikira pomanga mizere yobisika. Kukana kwake kutukuka kwa kuchuluka kwa mphamvu, mphamvu zazikulu ndi zowononga mtengo zimapangitsa kuti ikhale chisankho choyamba pa ntchito zachilengedwe zamagesi. Posankha zinthu zoyenera pamalo obisika, makampani achilengedwe amatha kukhalabe chitetezo komanso kudalirika kwa zomangamanga zawo, pamapeto pake amathandiza kupereka mafuta achilengedwe mpaka ogula.
