Yogwiritsidwa ntchito pofukula PC60-7 valve yothandizira hydraulic control valve 709-20-52300

Valavu yaikulu yothandizira imayikidwa pamwamba ndi m'munsi mwa valavu yaikulu yolamulira, imodzi pamwamba ndi pansi.Valavu imayika kupanikizika kwakukulu kwa hydraulic system yonse kuti igwire ntchito.Pamene kupanikizika kwa dongosolo kumadutsa kupanikizika kwa valve yaikulu yothandizira, valavu yaikulu yothandizira imatsegula kayendedwe ka mafuta a thanki yobwerera kuti iwononge mafuta a hydraulic kubwerera ku thanki kuteteza dongosolo lonse la hydraulic ndikupewa kuthamanga kwa mafuta kwambiri.

Momwe zimagwirira ntchito:

① Kuthamanga kwa PP kukwera;

② Kuposa 355kg/cm2 (380kg/cm2 pamene woyendetsa mafuta kuthamanga ON);

③ Pampu kukakamiza kukankhira mutu wokweza (2) kugonjetsa kasupe (1) kukakamiza kukankhira mmwamba;

④ Bowo laling'ono (okha φ0.5) mu plunger (3) limayamba kutulutsa mafuta;

⑤ Plunger (3) imakankhidwira m'mwamba chifukwa cha kusiyana kwapakati pakati pa kutsogolo ndi kumbuyo (yaikulu pansi, yaying'ono pamwamba);

⑥ Kukakamiza mafuta kubwerera ku thanki;

⑦ Kuthamanga kwapampu kutsika mpaka 355kg/cm2 (380kg/cm2 pamene woyendetsa mafuta kuthamanga ON)

Pamene mphamvu ya mpope ili yosakwana 355kg/cm2:

① Mutu wokweza (2) umatsekedwa ndi kukanikiza kasupe (1);

Mafuta samatuluka m’bowo laling’ono la plunger (3);

③ Kusiyana kwapakati pakati pa malekezero awiri a plunger (3) ndi 0, ndipo imabwerera pansi pa mphamvu ya masika ndi kuthamanga kwa mafuta;

④ Mafuta opanikizika amachotsedwa pa thanki;

⑤ Kuthamanga kwapampu kumatha kusungidwa;
