Hydraulic jack

1.Mfundo yogwiritsira ntchito hydraulic cylinder

Mfundo yotumizira ma hydraulic: ndi mafuta ngati sing'anga yogwirira ntchito, kudzera pakusintha voliyumu yosindikiza kuti asamutsire mayendedwe, kudzera kupsinjika mkati mwamafuta kusamutsa mphamvu.

2. Mitundu ya silinda ya hydraulic

Malinga ndi mawonekedwe amtundu wa hydraulic cylinder:

Malinga ndi zoyenda mumalowedwe akhoza kugawidwa mu mzere wowongoka reciprocating zoyenda mtundu ndi rotary swing mtundu;

Malinga ndi zotsatira za kuthamanga kwamadzimadzi, zitha kugawidwa kukhala chinthu chimodzi ndikuchita kawiri

Malinga ndi mawonekedwe mawonekedwe akhoza kugawidwa mu pisitoni mtundu, plunger mtundu;

Malinga ndi kuthamanga kalasi akhoza kugawidwa mu 16Mpa, 25Mpa, 31.5Mpa etc.

1) mtundu wa piston
Silinda imodzi ya pistoni ya hydraulic cylinder ili ndi malekezero amodzi okha a piston rod, mbali zonse ziwiri za madoko amafuta A ndi B amatha kupitilira kukakamiza kwamafuta kapena mafuta kubwerera, kuti akwaniritse kuyenda kwanjira ziwiri, komwe kumatchedwa silinda yochita zinthu ziwiri.

2) mtundu wa plunger

Plunger hydraulic cylinder ndi mtundu wa silinda imodzi yokha yama hydraulic cylinder, yomwe imatha kukwaniritsa njira imodzi ndi kuthamanga kwamadzimadzi Movement, plunger kubwerera kudalira mphamvu zina zakunja kapena kulemera kwa plunger.

Plunger imangothandizidwa ndi silinda ya silinda popanda kukhudzana ndi cylinder liner, kotero kuti cylinder liner ndiyosavuta kukonza, yoyenera kwa silinda yayitali ya hydraulic cylinder.

3.Hydraulic cylinder kukhazikitsa njira ndi zodzitetezera

1) Silinda ya hydraulic ndi malo ozungulira ayenera kukhala oyera, thanki yamafuta iyenera kusindikizidwa kuti iteteze kuipitsidwa, mapaipi ndi thanki yamafuta ziyenera kutsukidwa kuti ziteteze kugwa kwa oxide peel ndi zinyalala zina.

2） Clean with no velvet cloth or special paper, can not use hemp thread and adhesive as sealing material, hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure。

3) Kulumikizana kwa chitoliro sikungatheke.

4) Pansi pa silinda ya hydraulic hydraulic cylinder iyenera kukhala ndi kuuma kokwanira, apo ayi silinda ya silinda ikhale mu uta, yosavuta kuti ndodo ya pistoni ipinde.

5) Mzere wapakati wa silinda yosuntha yokhala ndi mpando wa phazi wokhazikika uyenera kukhala wokhazikika ndi mzere wapakati wa mphamvu yonyamula katundu kuti upewe mphamvu yapambuyo pake, yomwe ingapangitse chisindikizo kuvala ndikuwononga pisitoni, ndikusunga silinda ya hydraulic kufanana ndi kusuntha kwa chinthu choyenda pamtunda wa njanji, ndipo kufanana kwake sikuposa 0.05mm / m.
