Dongosolo lokhazikika la casing lomwe lili ndi midadada Chithunzi Chowonetsedwa

Concentric casing system yokhala ndi midadada

Kufotokozera Kwachidule:

Kubowola m'mapangidwe ndi zinthu zotayirira, zosaphatikizana nthawi zonse kumabwera ndi zovuta monga bore hole kulowa mkati kapena kugwa.Kodi mungapewe bwanji mavutowa?Pazaka zoyeserera komanso kafukufuku wazaka zambiri, tapanga makina opangira ma concentric casing system okhala ndi midadada yomangira maziko okhala ndi kubweza ndi miyala, kuya kwake mkati mwa 40 metres.

Concentric casing system yokhala ndi mapiko2

Khwerero 1: Kubowola kukayamba, makina amayendetsa nsapato ya casing ndi chubu choyika pansi.
Khwerero 2: Mukafika pamwala, kwezani dongosolo lotchinga, midadada imatsekedwa, sinthani kuzungulira ndikutulutsa chipikacho kuchokera padzenje.
Khwerero 3: Ngati dzenje lafika pakuya komwe mukufuna, malizitsani kubowola ndikupitilira njira ina.
Khwerero 4: Ngati mukufuna kubowola mozama, gwiritsani ntchito kachidutswa kakang'ono ka DTH kubowola mpaka kuya komwe mukufuna.
