Kutenga nthawi zambiri kumachitika ndi njira ina yakusintha machubu. Izi zingafunike kuzungulira kapena kufuna kukoka kukanikiza pa chingwe cha chubu.

Packer yokhazikika ndiyosavuta ndipo nthawi zambiri imapereka magwiridwe antchito apamwamba pazigawo zonse za kutentha ndi kupanikizika kuposa momwe amachitira paki yobweza. Nthawi zambiri, imakhala ndi mainchesi ang'onoang'ono akunja (OD), yomwe imapereka chilolezo chokulirapo mkati mwa chingwe cha casing kuposa zonyamula zobweza. OD yaying'ono komanso kamangidwe kake ka chopakira chokhazikika kumathandiza chidacho kuti chizitha kukambirana pamipata yothina ndi kupatuka kwa pachitsime. Packer yokhazikika imaperekanso mainchesi akulu kwambiri mkati (ID) kuti igwirizane ndi zingwe zokulirapo zamachubu ndi kumaliza kwa monobore.

Chojambulira chobwezacho chikhoza kukhala chofunikira kwambiri pa ntchito zotsika kwambiri / kutentha kwapansi (LP / LT) kapena zovuta kwambiri pamagetsi / kutentha kwambiri (HP / HT). Chifukwa chazovuta zamapangidwe awa pazida zapamwamba kwambiri, paketi yobweza yomwe imapereka magwiridwe antchito ofanana ndi a paketi yokhazikika nthawi zonse imawononga ndalama zambiri. Komabe, kumasuka kochotsa paketi pachitsime komanso zinthu zina, monga kukhazikikanso komanso kutha kugwiritsanso ntchito paketi nthawi zambiri, zitha kupitilira mtengo wowonjezera.

Musanasankhe chida, ndikofunikira kuganizira momwe magwiridwe antchito ndi mawonekedwe amapangidwe aliwonse, komanso momwe angagwiritsire ntchito. Nthawi zina, monga pamapulogalamu apamwamba kwambiri / kutentha kwambiri (HP/HT), wopakira okhazikika angakhale njira yokhayo.

Pakumalizidwa kwa mabowo ang'onoang'ono, zinthu zomwe ziyenera kuganiziridwa zikuphatikizapo kukakamiza kosiyana ndi kutentha kwa ntchitoyo, kuya kwa chitsime, kuyika komwe kufunidwa ndi njira yokhazikitsira, komanso kutsetsereka komaliza kwa chubu. Ndikofunikiranso kuganizira njira zogwirira ntchito zomwe zikuyembekezeredwa (kuyenda, kutsekera, jekeseni, kukondoweza) nthawi yonse ya moyo wa chitsime. Kusintha kwa machitidwe ogwirira ntchito kungakhudze kutentha, kupanikizika kosiyana, ndi katundu wa axial, zomwe zimakhudza wonyamula. Kumvetsetsa ntchito ndi malire a mitundu yosiyanasiyana ya paketi kudzakuthandizani kusankha mwanzeru.Ngati mukufuna Vigor's packer kapena zida zina zomwe zimagwiritsidwa ntchito pobowola pansi, chonde musazengereze kulumikizana nafe, tidzakupatsani zabwino kwambiri. zinthu zabwino kwambiri komanso ntchito yabwino kwambiri yopangira zinthu.
