Tlhahlobo e latelang e lebisa tlhokomelo ho sebopeho sa sebopeho, mekhoa ea ho tiisa, le ts'ebetsong ea ts'ebetso tlas'a maemo a matla.
1. Sebopeho sa Sebopeho le Maemo a Motheo a Mosebetsi
Sebopeho sa motheo sa sehokelo sa hydraulic ka kakaretso se na le likarolo tse tharo: 'mele o ka sehloohong (karolo e kopanyang), kopano ea ho tiisa, le mochini oa ho notlela. 'Mele o ka sehloohong o ikarabella bakeng sa ho hokahanya le melapo ea haeteroliki (joalo ka liphaephe tsa tšepe le li-hoses) kapa likarolo tsa haeteroliki (joalo ka lipompo, li-valve le li-cylinders). Sebopeho sa eona sa ka hare sa lebota se tlameha ho lumellana le bophara le sebōpeho sa mocha oa mokelikeli. Karolo ea ho tiisa ke karolo ea mantlha ea ts'ebetso, 'me mefuta e tloaelehileng e kenyelletsa O-rings (rabara kapa polyurethane), li-gaskets tse kopaneng (metsoako ea tšepe le ea rabara), kapa libaka tse tiisitsoeng tse thata (joalo ka bokaholimo ba khokahanyo). Mochine oa ho notlela o boloka le ho thibela ho hlephisa ha sehokelo ka likhokahano tse khoele (joalo ka maemo a NPT le BSPP), li-compression fittings (joalo ka SAE J514 compression fittings), kapa{6}mahanya manala a potlakang (joalo ka{7}}khatello kapele{8}fetola likhokahano tse sebelisoang hangata mochining oa kaho).
Ho latela pono ea ts'ebetso, likhokahano tsa hydraulic li tlameha ka nako e le 'ngoe ho fihlela litlhoko tse tharo tsa mantlha: pele, ho theha tsela e tsoelang pele ea mokelikeli ho netefatsa phallo ea oli e sa tsitsang; ea bobeli, ho mamella khatello ea ts'ebetso ea tsamaiso (ka tloaelo 10-50 MPa, empa e feta 100 MPa maemong a feteletseng) ntle le deformation ea polasetiki kapa ho phatloha; 'me ea boraro, ho boloka khatello ea tsamaiso e tsitsitseng ka ho thibela litsela tsa ho lutla ka hare le ka ntle ka karolo ea ho tiisa.
2. Mokhoa oa ho Tiisa: Tekanyo e Matla e Tsamaisang Ke Khatello
Ts'ebetso ea ho tiisa ha li-hydraulic fittings ke motheo oa ts'ebetso ea bona. Molao-motheo oa eona o theiloe holim'a mekhoa e 'meli ea "khatello ea boithati-ea ho itlama" le "pre{2}}matšeliso a khatello." Ha tsamaiso ea hydraulic e sebelisoa, mokelikeli o hlahisa khatello ea pele tlas'a ketso ea pompo. Nakong ena, matla a hatellang karolong ea ho tiisa a eketseha ha khatello e ntse e phahama. Mohlala, selikalikoe sa O- se hatelloa ka radially, 'me sebaka sa eona sa ho kopana le khatello ea ho kopana li eketseha ka nako e le' ngoe, ho tlatsa likheo tse nyenyane haholo pakeng tsa 'mele o moholo le sehokedi (joaloka mekoti e bakoang ke ho ba mahoashe holimo). Bakeng sa li-conical seal (tse kang 74℃taper angle of hydraulic pipe fittings),-oli ea khatello e phahameng e sebetsa ka morao holim'a sebaka se tapered, se sutumelletsa libaka tse koalang haufi, ho hlahisa maikutlo a nepahetseng: "ha khatello e phahame, tiiso e tiisa le ho feta."
Ke habohlokoa ho hlokomela hore ho tiisa ha hoa itšetleha feela ka elasticity ea lintho tse bonahalang. -Moetso oa pele oa compression o bohlokoa. Ka mohlala, O-rings e hloka 15%-30% compression ratio nakong ea ho kenya (theko e khethehileng e itšetlehile ka boima ba rabara le mocheso oa ho sebetsa) ho netefatsa ho tiisoa ha pele le tlas'a khatello e tlaase. Tlas'a{{8}maemo a khatello e phahameng, karolo e koalang e tlameha ho hanana le extrusion (mohlala, fiber-reinforced polyurethane O{11}}rings) 'me e hana ho bola ha media (mohlala, fluoroelastomer e loketseng maro a hydraulic hydraulic). Khatello ea pele{12} e sa lekaneng e ka lebisa ho -ho lutla hanyane ka likhatello tse tlase, athe ho petetsa ho feteletseng ho ka etsa hore ho be thata ho tiisa bokaholimo kapa ho thatafalletsa ho kopanya le ho qhaqha.

Ts'ebetsong ea 'nete, likhokahano tsa haeteroliki li tlameha ho mamella ho feto-fetoha ha khatello khafetsa (joalo ka ho phahama ha nako e telele-ho bakoang ke hydraulic shock), ho fetoha ha thempereichara (ho sebetsa ho feta mocheso o fapaneng oa likhato tse -40 ho isa ho +120), le ho sisinyeha ha mochini (joalo ka ho thothomela ho sa khaotseng ha mochini oa kaho). Ho rarolla mathata ana, molao-motheo oa eona oa ts'ebetso o fihlella botsitso ka mekhoa e latelang:

Ha ts'oaetso ea hydraulic e etsahala tsamaisong, sebopeho sa damping se lelefatsa nako ea ho phahama ha khatello 'me se thibela ho hlōleha ha tiiso ka lebaka la ho imeloa ke nakoana. Mohlala, lihokelo tse ling tse phahameng-li na le likanale tsa spiral flow tse ka hare tse eketsang tsela ea oli ho fokotsa matla a ts'oenyehileng.
