Mfundo yogwiritsira ntchito ndi njira yogwiritsira ntchito mawindo a overshot

1. Kapangidwe ka mazenera opitilira muyeso

Kuwotcha kwazenera kumalumikizidwa ndi mbali ziwiri za thupi la silinda ndi cholumikizira chapamwamba (komanso kulumikizana kwa ulusi)

Malingana ndi zosowa za salvage, mapeto apansi a silinda amatha kupangidwa m'magulu anayi osiyanasiyana:

(1) Kudula kwa spiral semi-oblique ndikosavuta kuzungulira ndikudziwitsa nsomba.

(2) Kudula nsapato za zigzag ndikosavuta kuyika mphero kuyeretsa zinthu zolimba zomwe zili pamwamba pa nsomba ndikuwongolera nsomba kuti zilowemo.

(3) Mlomo wa belu wa chulucho wamkati ndi wosavuta kuyambitsa nsomba mwachindunji.

(4) Chodulira chooneka ngati ntchentche Phatikizani chogwira ndi mazenera opitilira muyeso kuti muwonjezere kusodza.

2. Ntchito mfundo ya zenera overshot

Nsomba zikalowa mu silinda ndikukankhira pawindo lawindo, lilime lazenera limatambasula kunja, mphamvu yake yobwereranso imaluma thupi la nsomba mwamphamvu, ndipo lilime lazenera limagwiranso mwamphamvu masitepe, ndiko kuti, nsomba imagwidwa.

3. Ntchito njira ya zenera overshot

(1) Onani ngati ulusi kapena ma welds a gawo lililonse ali osasunthika komanso olimba. Yesani ngati kukula kwa lilime la zenera ndi kuchepera kwamkati mkati mwa malo otsekedwa kungagwirizane ndi nsomba, ndipo sungani chithunzicho kuti mufufuze.

(2)Borani pansi mpaka 2 ~ 3m pamwamba pa nsomba, ndipo yambani mpope kutsuka chitsime. Pang'onopang'ono tembenuzani chingwe chobowola kuti muchepetse. Yang'anani kusintha kwa sikelo yolemera ndi malo olowera, kumbukirani kugwira nsomba kuti ilowe, ndikuwongolera silinda kuti ilowe mu nsomba.

(3)Pitirizani kutsitsa chingwe chobowola kuti nsomba zilowe mkati mwa mbiya ya zida. Ngati kutalika kwa zinthu zomwe zikugwa ndi zazifupi, chitsimecho ndi chakuya, ndipo zimakhala zovuta kuweruza malo olowera ndi kusintha kwa kulemera kwa kuyimitsidwa, chingwe chobowolacho chikhoza kukwezedwa ndi 1-2m pambuyo pa nsomba imodzi, kenako n'kuzunguliridwa. kutsitsa. Bwerezani kangapo kuti mukweze kubowola.

(4) Pokweza chobowolacho, chiyenera kuyendetsedwa bwino. Musakhudze nsomba ndikugunda chingwe chobowola mwadzidzidzi, kuti musagwedeze nsomba ndikugweranso m'chitsime.
