Umehluko omkhulu phakathi kompakishi kanye nepulaki yebhuloho ukuthi umpakishi ngokuvamile ushiywa emthonjeni okwesikhashana ngesikhathi sokuqhekeka, ukufakwa kwe-asidi, ukutholwa kokuvuza nezinye izinyathelo, abese ephuma nentambo yepayipi ngemva kokuqedwa kokwakhiwa; kuyilapho ipulaki yebhuloho isetshenziselwa ukukhiqiza uwoyela ongqimbeni lokuvala Ngenkathi ulinde izinyathelo, yishiye emthonjeni isikhathi esithile noma unomphela. Amapulaki ebhuloho ahlanganisa amapulaki ebhuloho ahlala njalo, amapulaki afinyelelekayo ebhuloho, namapulaki ebhuloho ashayelekayo.
Ngaphandle kophawu, wonke umzimba wompakishi wenziwe izingxenye zensimbi, ezingavalwa. Ngokuvamile, umthombo ugcinwa ngesikhathi esifanayo nentambo yokuvala. Ngesibambo sokukhulula, umthombo ungagcinwa ngokuhlukana. Umehluko wengcindezi uphansi uma kuqhathaniswa (ngaphandle kwama-fracturing seal). . Mayelana nezindlela zokudoba, amapulaki ebhuloho angahlukaniswa abe yizinhlobo ezintathu: ezidotshwayo, ezishayekayo nezidotshwayo nezishayelekayo. Wonke angamathuluzi okuvala ashiya imithombo yodwa futhi anokumelana nokucindezela okuphezulu. Lezo ezingadotshwa ziyefana nalezo zophawu lokujikijela; okungase kubhojwe ngokuyisisekelo izingxenye zensimbi ezisansimbi ngaphandle kweshubhu eliphakathi nendawo; igobolondo, ishubhu eliphakathi nendawo namajoyinti angadotshwa futhi abhojwe zonke izingxenye zensimbi, futhi iziliphu zenziwe ngensimbi ekhonjiwe. Ngaphezu kwalokho, amapulaki ebhuloho nawo anama-valve phansi, futhi ungqimba olungezansi lungavulwa futhi luvalwe nge-cannula ekhethekile. Lona umehluko oyisisekelo phakathi kwamapaki namapulaki ebhuloho.
Kokubili abapakishi namapulaki ebhuloho asetshenziselwa ukuhlukanisa izigaba ezimbili, kodwa indawo ephakathi yesipakishi ayinalutho, okuvumela uwoyela, igesi namanzi ukuthi kugeleze ngokukhululeka, kuyilapho indawo ephakathi yepulaki yebhuloho iqinile futhi ivalwe ngokuphelele.
