Chitsimecasing headamatanthauza nkhokwe yomwe imayikidwa pachitsime pobowola.Ntchito yake yayikulu ndikuteteza chitsime ku kuwonongeka kwa chilengedwe chakunja, ndipo ingagwiritsidwe ntchito kulumikiza mapaipi obowola ndi zitsulo zoboola.Mitu ya Wellhead casing ingagwiritsidwenso ntchito powongolera madzi ndi gasi, mwachitsanzo, kuwongolera kuthamanga ndi kuyenda pakubowola.
Mutu wa casing wa wellhead ungagwiritsidwenso ntchito kulumikiza zida zina zobowola, monga zida zodula mitengo, zida zoyezera mphamvu, zida zoyezera kutentha, etc. Itha kugwiritsidwanso ntchito kulumikiza mapaipi obowola, mwachitsanzo, kulumikiza mapaipi obowola ndi nsanja zoboola.
Zida zomwe zimagwiritsidwa ntchito kwambiri pamutu wa casing headhead ndi zitsulo, aluminiyamu alloy, copper alloy, etc., ndipo kukula ndi mawonekedwe ndizosiyana.Kuyika kwa chitsimecasing headziyenera kuchitidwa mosamalitsa malinga ndi zomwe zafotokozedweratu kuti zitsimikizire kuyika kolondola komanso kugwiritsa ntchito bwino mutu wa casing headhead.
Pobowola, mutu wa chitsime cha chitsime ndi gawo lofunikira.Sikuti amangoteteza chitsime ku kuwonongeka kwa chilengedwe chakunja, komanso angagwiritsidwe ntchito kulumikiza mipope kubowola ndi bits, kulamulira madzimadzi ndi mpweya, kulumikiza zida zina pobowola, kulumikiza pobowola payipi.Pobowola, kusankha ndi kuyika mitu yobowola bwino kumafunika kutsatira mosamalitsa zomwe zafotokozedwazo, kuti zitsimikizire chitetezo ndi magwiridwe antchito akubowola.
Kuphatikiza pa ntchito zomwe zili pamwambapa, mutu wa casing wa wellhead uli ndi ntchito zina zofunika.Mwachitsanzo, pobowola chitsime chopingasa, mutu wa casing wa chitsime ukhoza kugwiritsidwa ntchito kusintha njira yobowola kuti zitsimikizire kulondola kwa njira yobowola.Kukankha bwino kumatha kuchitika pobowola, ndipo mutu wabowo ungagwiritsidwenso ntchito kuwongolera kukankha kuwonetsetsa kuti ntchito yoboola ili yotetezeka.Kuonjezera apo, mutu wa chitsime ukhoza kugwiritsidwanso ntchito kusindikiza pamutu kuti zisawonongeke ndi kuipitsidwa ndi malo ozungulira.Atha kugwiritsidwanso ntchito ngati ngalande pachitsime kuti madzi asachuluke pachitsime.
Mwachidule, mutu wa chitsime cha chitsime ndi gawo lofunika kwambiri pakubowola, ndipo kusinthasintha kwake ndi kufunikira kwake kumawonekera.
Pobowola, kusankha ndikuyika mitu yachitsime chamadzi kuyenera kutsatiridwa mosamalitsa.Choyamba, zida zoyenera zamutu wamutu ziyenera kusankhidwa molingana ndi kuya kwake ndikubowola.Nthawi zambiri, pamene kuya kwa kubowola kukuchulukirachulukira, mutu wa chitsime cha chitsime umafunikira kukana kupanikizika kwambiri.M'malo otentha komanso othamanga kwambiri, ndikofunikira kugwiritsa ntchito kutentha kwambiri komanso kuthamanga kwambiri kwamutu wokhazikika wamutu.Kachiwiri, pakuyika mutu wa casing wa chitsime, uyenera kukhazikitsidwa molingana ndi kukula ndi mawonekedwe a chitoliro chobowola.Kawirikawiri, kukula kwa mutu wa casing wa chitsime kuyenera kufanana ndi kukula kwa chubu chobowola.Pakuyika, chidwi chiyenera kulipidwa pakukhazikika ndi kukhazikika kwa mutu wa casing wa chitsime kuti zitsimikizire kulimba kwa kukhazikitsa.
Pomaliza, pakubowola, momwe mutu wa chitsime umayendera uyenera kuyang'aniridwa pafupipafupi kuti azindikire ndikuwongolera zovuta zilizonse munthawi yake.Izi zitha kuwonetsetsa kugwiritsidwa ntchito kwabwino kwa mutu wa casing headhead ndi chitetezo pakubowola.
