Dn80 ikidozi cya tankum tank ireremba

Dn80valve irerembaigizwe n'umupira ureremba, gutwara igice, no kugenzura icyuma bigenzurwa nuruhererekaneko cyongerewe hydeudic. Piston ikoresha gahunda yigitutu gitandukanye, kandi hejuru yikidodo cyo hejuru ni kinini kuruta iy'ikibanza gikurikira. Amavuta yigitutu aho isoko yamavuta yinjira muri kaburimbo yo hagati ya piston icyo gihe yinjira mu myuka yo hejuru ya piston. Vent hagati ya piston igenzurwa numushinyaguzi ihuza na tank ya peteroli. Iyo urwego rwamazi rwamavuta ari ibisanzwe, buoyancy yumupira ureremba yimurwa binyuze muri lever kandi yiyongera, kugirango ugire umutware usanzwe wumushinyaguke hejuru ya piston. Kubwumuvuduko watewe numuvuduko wamavuta yigitutu kugirango winjire mu mwobo wo hejuru wa piston ahantu hanini muri piston nini kuruta agace ka kashe kari hepfo. Imikorere ya piston yimuka hepfo kandi ikandarikana cyane hejuru yikimenyetso. Valve ikomeje gufungwa.
Buoyancy yumupira ureremba igabanuka hamwe nurwego rwamazi ya tank ya peteroli. Iyo imbaraga zihamye ari nini kuruta imbaraga zihamye zatewe na buoyancy yumupira utandukana, umushinyaguzi wimuka iburyo hamwe nimico yo hagati ya Piston irakinguwe. Amavuta yigiturire mu mwobo wo hejuru wa Piston yamenetse ku tank ya peteroli ya vacuum, kandi amavuta yo mu mwobo wo hagati ya Piston asunika peston iburyo kandi akingura valve kuri tank ya peteroli. Iyo amazi-urwego ruzamuka kumwanya runaka, buoyancy yumupira ureremba wiyongera kandi inshinge ya valve irakandaga cyane kuruhande rwa Centre. Ubwonko bwo hejuru bwa Piston bufitanye isano nisoko yamavuta yumuvuduko. Thevalveirafunze kandi amavuta arangiye. Inzira ya peteroli-itanga hamwe nimpinduka zurwego rwibintu buhoro. Gucomeka inshinge hamwe na piston bigenda icyarimwe. Ihame rikora ni kimwe na valve-drain valve kugirango ugenzure urwego rwibigega.
