1. Mfundo ya kapangidwe ka zinthu
Pulagi yolumikizira phulusa yomwe ingathe kubwezeretsedwa imakhala ndi chosindikizira cha mpando ndi njira yolumikizira, njira yotsekera ndi kutsegula, chosinthira cha manja chotsetsereka ndi njira yoletsa kumatira, njira yolowetsa machubu ndi njira yopulumutsira.
Chida chokhazikitsira chingwe kapena chida chokhazikitsira mafuta cha hydraulic payipi chingagwiritsidwe ntchito kutumiza pulagi ya mlatho pamalo omwe adakonzedweratu kuti ayike ndikutaya, kenako kuchotsa chida chokhazikitsira ndi kudyetsa, kuyika chida chokhazikitsira mu pulagi yokhazikitsira phulusa, ndikuchita ntchito yokanikiza phulusa. Mukakanikiza phulusa, kwezani chubu chokhazikitsira ndikutsuka chitsime. Mukayika koyamba matope, onjezerani pamwamba kuti muchotse pulagi ya mlatho.
2. Njira yogwirira ntchito
1. Kukhazikitsa ndi kutsegula ntchito ndi chimodzimodzi ndi ntchito yachizolowezi yotsekera.
2. Pambuyo poti pulagi yofinyira phulusa yakhazikitsidwa, lumikizani kannula yofinyira phulusa pansi pa chingwe cha chubu ndikuyiyika mu chitsime, ikani mu mandrel ya pulagi yofinyira phulusa ya mtundu wa recovery, ndikukankhira valavu yotsetsereka.
3. Sinthani matope a simenti ndi galimoto yopangira simenti kuti mugwiritse ntchito kufinya phulusa.
4. Phulusa likatha kufinyidwa, tulutsani chingwe cha chitoliro nthawi yomweyo, tulutsani chitoliro cholowetsa madzi kuti mutseke valavu yotsatsira, ndipo nthawi yomweyo tsukani chitolirocho kuti mutsuke matope ochulukirapo a simenti kuchokera m'chitoliro. Chifukwa valavu yotsatsira imatsekedwa, matope a simenti omwe ali kunja kwa kapangidwe kake kapena chitolirocho sangabwererenso m'chitolirocho, zomwe zimatsimikizira kuti matope a simenti ndi abwino komanso kuti matopewo azitsekeka, zimafupikitsa nthawi yokhalamo kwa matope a simenti m'chitolirocho, ndikuchepetsa chingwe cha matope a simenti.
5. Ngati gawo lapamwamba likugwiritsidwa ntchito, Retrievable Bridge Plug of Cement Squeeze imagwiritsidwa ntchito ngati chisindikizo chofala cha mlatho ndipo ikhoza kuyikidwa mu kupanga mwachindunji; ngati gawo lapansi lakumbidwa, chingwe chosungiramo zinthu chosatsekedwa chimayikidwa m'chitsime kuti chichotse pulagi ya mlatho. Pulagi ya mlatho ikatulutsidwa, ikani nsapato zopukutira pansi pa chitsime kuti muboole pulagi ya simenti. Popeza palibe zitsulo, kuboola ndi kupukuta n'kosavuta.
3. Mbali zaukadaulo
1. Njira yosinthira yosinthika: Pulagi ya mlatho ikhoza kutumizidwa mu chokonzera pogwiritsa ntchito chida chosinthira chamtundu wa chingwe kapena chida chosinthira cha hydraulic, ndipo chida choyenera chosinthira chingasankhidwe malinga ndi momwe chitsime chilili.
2. Kuwongolera kolondola kwa malo: Mphamvu yokhazikitsira ya pulagi ya mlatho imayendetsedwa ndi ndodo yokakamiza (mphete), yomwe imatsimikizira kuti pulagi ya mlatho imakhala yotetezeka komanso yodalirika. Nthawi yomweyo, imatsimikizira kuti chida chokhazikitsira chikhoza kuchotsedwa bwino m'bowo la chitsime pansi pa zovuta.
3. Kapangidwe kodalirika koletsa kutsekeka: Gawo lotsetsereka limagwiritsa ntchito kapangidwe kotsekeka komwe kali mkati, ndipo pulagi ya mlatho sikophweka kukumana ndi kukana ndi kutsekeka ikakwezedwa ndikutsitsidwa mu shaft. Pambuyo poyika, zotsekeka za pulagi ya mlatho ndi chubu cha rabara zimayikidwa pakati pawokha, ndipo zitha kugwiritsidwa ntchito mosamala m'zitsime zokhala ndi zitsime zilizonse zopendekera komanso zopingasa.
4. Njira yapadera yomangira: Pulagi ya mlatho imagwiritsa ntchito kuphatikiza kwanzeru kwa ma slip, ma slip cones, ndi ma slip outer cylinders. Ili ndi mphamvu yabwino yonyamula mphamvu ya bidirectional pressure ndipo ingagwiritsidwe ntchito pa ma casing amitundu yosiyanasiyana.
5. Njira yotsekera yotetezeka: Kutsegula pulagi ya mlatho kumachitika pang'onopang'ono motsatira dongosolo la njira yotsekera, njira yotsekera, ndi njira yotsetsereka. Kaya mphamvu zapamwamba ndi zotsika za pulagi ya mlatho zili bwino, mphamvu yotsekera yofunikira ndi yochepa kwambiri.
6. N'zosavuta kuboola ndi kupukuta pulagi ya phulusa: pulagi ya mlatho wobwezeretsanso phulusa ikatha kufinyidwa, pulagi ya mlatho imatha kuchotsedwa, ndipo n'zosavuta kuboola ndi kupukuta pulagi ya phulusa.
7. Ali ndi kuthekera koboola: pulagi ya mlatho ili ndi kapangidwe kakang'ono, kapangidwe kake kapamwamba kamapangidwa ndi zipangizo zomwe zimatha kuboola bwino, ndipo njira yotsekera mkati ili pamwamba pa pulagi ya mlatho, ngakhale pulagi ya mlatho singachotsedwe pazifukwa zachilendo, ikhoza kukhala yosavuta kuboola.
