Zigawo zazikulu ndi makhalidwe ogwiritsira ntchito zida zamachubu ozungulira.

Zigawo zazikulu za zida zolumikizira mapaipi.

1. Ng'oma: imasunga ndi kutumiza machubu ozungulira;

2. Mutu wa jakisoni: umapereka mphamvu yokwezera ndi kutsitsa chubu chozungulira;

3. Chipinda chogwirira ntchito: Ogwiritsa ntchito zida amayang'anira ndikuwongolera machubu ozungulira apa;

4. Gulu la mphamvu: gwero la mphamvu ya hydraulic lofunikira kuti ligwiritse ntchito zida zamachubu ozungulira;

5. Chipangizo chowongolera chitsime: chipangizo chotetezera mutu wa chitsime pamene chubu chozungulira chikugwiritsidwa ntchito mopanikizika.

Chipangizo chowongolera chitsime

Zipangizo zowongolera zitsime ndi gawo lina lofunika kwambiri pa ntchito zozungulira mapaipi. Chipangizo chowongolera zitsime chozungulira chimaphatikizapo choletsa kuphulika (BOP) ndi bokosi lozungulira kuphulika lolumikizidwa kumtunda kwa BOP (ntchito zozungulira mapaipi opitilira kuthamanga kwambiri nthawi zambiri zimakhala ndi mabokosi awiri ozungulira ndi BOP yowonjezera). Zipangizo zonsezi ziyenera kuganizira za kuthamanga kwawo ndi kutentha koyenera zikagwira ntchito pamalopo.

Bokosi loletsa kuphulika lili ndi chinthu chotsekera, chomwe chimagwiritsidwa ntchito kupatula makina opanikizika omwe ali mu chitsime. Nthawi zambiri chimayikidwa pakati pa BOP ndi mutu wa jakisoni. Bokosi loletsa kuphulika limagawidwa m'mitundu iwiri: chisindikizo champhamvu ndi chisindikizo chosasinthasintha. Chipangizo choletsa kuphulika chimapangidwa ngati chitseko cham'mbali kuti chithandize kusintha zinthu zotsekera za chubu chozungulira pamene chili m'chitsime.

BOP imalumikizidwa kumapeto kwa bokosi loletsa kuphulika ndipo ingagwiritsidwenso ntchito kuwongolera kuthamanga kwa mpweya. Malinga ndi zofunikira pa ntchito zozungulira mapaipi, BOP nthawi zambiri imapangidwa mwapadera, kuphatikiza mapeyala angapo a nkhosa zamphongo, iliyonse ili ndi ntchito yake yapadera. Dongosolo la zipata zinayi ndilo BOP yodziwika kwambiri yomwe imagwira ntchito.

Makhalidwe ogwirira ntchito a chubu chozungulira

1. Ntchito yochotsa zinthu m'thupi.

2. Musasunthe chingwe cha chubu m'chitsime kuti muteteze chubu chopangira.

3. Kutha kumaliza ntchito zina zomwe sizingatheke pogwiritsa ntchito njira zachikhalidwe.

4. M'malo mwa ntchito zina zachizolowezi, magwiridwe antchito ndi ubwino wake zimakhala zapamwamba.

5. Yosunga ndalama, yosavuta komanso yosunga nthawi, yotetezeka komanso yodalirika, komanso yogwiritsidwa ntchito kwambiri.
