A na-etinye valvụ enyemaka isi na elu na njedebe nke valvụ nchịkwa isi, otu elu na nke ala. valvụ ahụ na-edozi nrụgide kachasị maka usoro hydraulic dum na-arụ ọrụ. Mgbe nrụgide usoro ahụ karịrị nrụgide setịpụrụ nke valvụ enyemaka isi, valvụ enyemaka bụ isi na-emepe sekit mmanụ nke tankị nlọghachi iji jupụta mmanụ hydraulic azụ na tank iji chebe usoro hydraulic dum ma zere nrụgide mmanụ dị ukwuu.

Ka o si arụ ọrụ:

① Mgbapụta mgbapụta PP na-ebili;

② Karịrị 355kg / cm2 (380kg / cm2 mgbe mmanụ ụgbọelu na-agbanye ọkụ);

③ Nrụgide mgbapụta ịkwanye isi ebuli elu (2) imeri mmiri (1) ike ịkwaga elu;

④ Obere oghere (naanị φ0.5) na plunger (3) na-amalite inwe mmanụ mmanụ;

⑤ The plunger (3) na-ebuli elu n'ihi nrụgide dị iche n'etiti ihu na azụ (nnukwu n'okpuru, obere n'elu);

⑥ Mmanụ nrụgide azụ na tank;

⑦ Nrụgide mgbapụta na-adaba na 355kg / cm2 (380kg / cm2 mgbe mmanụ ụgbọ elu ON)

Mgbe mgbapụta mgbapụta na-erughị 355kg / cm2:

① A na-emechi isi ihe na-ebuli elu (2) n'okpuru nrụgide nke mmiri (1);

Enweghị mmanụ na-eru n'obere oghere dị na plunger (3);

③ Ọdịiche nrụgide dị n'etiti nsọtụ abụọ nke plunger (3) bụ 0, ọ na-alaghachikwa n'okpuru ọrụ nke ike mmiri na nrụgide mmanụ;

④ A na-ewepụ mmanụ nrụgide site na ụzọ tank;
