Uhlobo ngalunye lwesilinda ye-hydraulic lubonelela ngeentlobo ezahlukeneyo zamandla. Iinjineli zikhetha ngokusekelwe kwiimfuno zomthwalo kunye noyilo lwenkqubo.
Umahluko wobubanzi beBore kunye nempembelelo yawo ekusebenzeni kwamandla okuphuma kweSilinda
Ubudlelwane Phakathi Kokudinwa Nokunyanzela
Ububanzi bembobo bumisela amandla okukhupha isilinda ye-hydraulic. Imbobo enkulu ivelisa amandla angakumbi. Le fomyula ilula:
Apho:
- F= Amandla ethiyori (amaNewton)
- D= Ububanzi bembobo (mm)
- P= Uxinzelelo lwenkqubo (MPa)
Iindidi zobungakanani beBore:
Ubungakanani obahlukeneyo bebhore busebenza ngeenjongo ezahlukeneyo:

Ububanzi bePiston Rod bubalulekile kakhulu
Ububanzi bentonga yepiston budla ngokuba yi-30% ukuya kwi-70% yobukhulu bebhore. Intonga etyebileyo imelana nokugoba ngcono. Oku kubalulekile xa kugotywa ixesha elide okanye kumthwalo osecaleni. Xa kugotywa ngaphezulu kwe-1.5 yeemitha, uyilo oluchasene nokugoba luba luyimfuneko. Ngaphandle koyilo olufanelekileyo, intonga inokugoba phantsi komthwalo.
Xa ukhetha isilinda se-hydraulic, qwalasela ubukhulu bebhore kunye nenduku. Umxube ochanekileyo uqinisekisa ukusebenza okuthembekileyo kunye nobomi benkonzo ende.
Isikhokelo soKhetho lwezinto ezisetyenzisiweyo kwiityhubhu zeSilinda, iiPiston Rods, kunye neenxalenye eziphambili
Izixhobo zeSilinda Tube
Ityhubhu yesilinda ibamba ioyile ye-hydraulic kwaye ikhokela i-piston. Ukhetho lwezinto luxhomekeke kuxinzelelo kunye nendawo engqongileyo:
| Izinto eziphathekayo | Iipropati | Uvavanyo loxinzelelo | Amanqaku |
|---|---|---|---|
| #20 Intsimbi Engenamthungo | Ikhabhoni ephantsi, ukuwelda okuhle, ixabiso eliphantsi | Iphantsi (≤10MPa) | Ifuna ukuhluzwa ukuya kwiRa ≤0.4μm |
