Khetho ea Bohlokoa Ts'ebetsong ea Valve ea Solenoid: Tataiso ea ho Khetha Lisebelisoa tsa ho Tiisa​

Selelekela​

Ka boiketsetso ba indasteri, di-valve tsa solenoid di sebetsa e le dikarolo tsa bohlokwa bakeng sa ho laola phallo ya mokelikeli ditshebedisong ho tloha tlhahisong le ts'ebetsong ya dikhemikhale ho isa ho eneji le tlhokomelo ya bophelo. Le hoja moralo wa di-valve le bokgoni ba motlakase di atisa ho fumana tlhokomelo e kgolo, kgetho ya thepa ya ho kwala​ e ntse e le ntlha ya bohlokwa tshebetsong ya nako e telele. Ditiiso di thibela ho dutla ha ka hare le kantle, di boloka botsitso ba kgatello, mme di hanela ho senyeha ho tswa ho metswedi ya phatlalatso, mocheso le potoloho ya tshebetso. Ho ahlola hampe ho tsamaellana ha tsona le maemo a tshebetso ho ka lebisa ho hloleheng pele ho nako, dikotsi tsa polokeho, le nako e jang nako e sa rerilweng ya ho se sebetse. Sengoloa sena se hlahloba di-polymer tse tharo tse sebediswang haholo tsa ho kwala—NBR, FKM, le EPDM—mme e fana ka moralo o hlophisitsoeng bakeng sa ho bapisa thepa ea thepa le litlhoko tsa ts'ebeliso.

1. Karolo ea Litiiso ho Tšepahalang ha Valve ea Solenoid

Litiiso tse ka har'a li-valve tsa solenoid li etsa mesebetsi e mengata ea bohlokoa:

Ho Thibela ho Dutla ha Metsi: Ka ho theha dithibelo tse thata pakeng tsa dikarolo tse tsamayang le mmele wa di-valve, ditiiso di netefatsa hore ha ho dutla ha letho ditshebedisong tse sa fetoheng le tse fetohang.

Ho Hanela Lik'hemik'hale: Li lokela ho mamella ho pepesehela lintho tse mabifi, ho kenyeletsoa oli, li-acid, li-solvent, kapa mouoane, ntle le ho ruruha, ho petsoha, kapa ho senyeha.

Ho Ikamahanya le Mocheso: Litiiso li boloka ho tenyetseha ho pholletsa le maemo a feteletseng a mocheso, ho tloha maemong a cryogenic ho ea libakeng tsa mouoane tse nang le mocheso o phahameng.

Ho Tšoarella ha Mekaniki: Li mamella khatello le khohlano e pheta-phetoang e bakoang ke ts'ebetso ea li-valve, li hanela ho tsofala le ho tsoa ha tsona ka lipotoloho tse limilione.

Khetho e fosahetseng ea thepa e ka lebisa ho tieheng ha sekwahelo, ho ntšeng ha sona, kapa ho bola ha lik'hemik'hale—lisosa tse tloaelehileng tsa ho hloleha ha valve.

2. Lisebelisoa tsa ho Tiisa Senotlolo: Thepa le Litšebeliso​

2.1 NBR (Rubber ea Nitrile Butadiene)​

Matla a Bohlokoa: E hanyetsa hantle oli, mafura le mafura a thehiloeng ho diminerale, e leng se etsang hore e be tharollo e theko e tlaase bakeng sa litsamaiso tsa hydraulic le pneumatic. E boetse e fana ka khanyetso e ntle ea ho khohlela le matla a ho thaepa.

Meeli: E kotsing ea ozone, ho pepesehela UV, le li-solvents tse thehiloeng ho ketone/ester; mocheso o sebetsang o moqotetsane ho feta li-polymer tse tsoetseng pele.

Maemo a mocheso: -30°C ho isa ho +100°C (nako e khuts'oane).

E Loketseng: Litsamaiso tsa moea tse hatelletsoeng, mela ea mafura a enjene, taolo ea mafura, le li-hydraulic tsa indasteri tse sebelisang oli ea liminerale.

2.2 FKM (Rabara ea Fluorocarbon)​

Matla a Bohlokoa: Ho hanyetsa mocheso o phahameng, lik'hemik'hale le oxidation ka tsela e ikhethang. Litiiso tsa FKM li sebetsa ka mokhoa o tšepahalang mefuteng e matla, ho kenyeletsoa le li-acid, oli tsa maiketsetso le li-hydrocarbon tse nkhang hamonate.

Meeli: Litšenyehelo tse phahameng; ho tenyetseha ho fokolang mochesong o tlase; ha e lumellane le li-ketone, li-ester le ammonia.

Maemo a mocheso: -20°C ho isa ho +200°C (litlhōrō tsa nako e khuts'oane ho fihlela ho 230°C).

E Loketseng: Ts'ebetso ea lik'hemik'hale, lisebelisoa tsa meriana, lithapo tsa mouoane tse nang le mocheso o phahameng, le litsamaiso tsa turbo tsa likoloi.

2.3 EPDM (Ethylene Propylene Diene Monomer)​

Matla a Motheo: E hanyetsa metsi a chesang haholo, mouoane, ozone le ho putlama ha metsi. E boetse e mamella maro a phosphate ester (mohlala, Skydrol) le ho fokotsa li-acid/alkali.

Meeli: Ha e lokele ho sebelisoa oli ea diminerale kapa mafura; ho pepesehela oli ho baka ho ruruha le ho hloleha kapele.

Maemo a mocheso: -40°C ho isa ho +150°C (nako e khuts'oane).

E Loketseng: Mekhoa ea ho phekola metsi, lipotoloho tsa ho pholisa, ts'ebetso ea lijo le lino, le li-hydraulic tsa lifofane tse sebelisang li-phosphate esters.

3. Tlhahlobo ea Papiso: Ho Khetha Boitsebiso bo Nepahetseng

Tafole e ka tlase e akaretsa litšobotsi tsa bohlokoa tsa ts'ebetso:

4. Mokhoa o Hlophisitsoeng oa Khetho​

Mohato oa 1: Hlalosa Mecha ea Litaba ea Mokelikeli​

Metsi, mouoane, kapa joala: EPDM hangata e sebetsa hantle ka lebaka la botsitso ba eona ba metsi.

Oli, mafura, kapa li-hydrocarbon: NBR kapa FKM li loketse, 'me FKM e khethoa bakeng sa mocheso o phahameng kapa maro a maiketsetso.

Mecha ea phatlalatso e mabifi ea lik'hemik'hale: Netefatsa ho lumellana ho sebelisoa lichate tsa ho hanyetsa lik'hemik'hale; hangata FKM e fana ka khanyetso e pharaletseng.

Mohato oa 2: Lekola Mocheso le Khatello​

Tikoloho tse nang le mocheso o phahameng​ (>150°C): FKM kapa li-polymer tse khethehileng (mohlala, FFKM) lia hlokahala ho qoba ho tsofala ka potlako.

Ditshebediso tsa cryogenic: Disebediswa tse thehilweng ho EPDM kapa PTFE di boloka ho tenyetseha ha mocheso o le tlase.

Maemo a feteletseng a kgatello: Netefatsa hore matla a mechini a tiiso le moralo wa ho thibela ho ntsha ha sekheo di tsamaellana le kgatello ya sistimi.

Mohato oa 3: Hlahloba Litšitiso tsa Bophelo Bohle le Litšenyehelo​

Litsamaiso tsa nako e khuts'oane, tse seng tsa bohlokoa: NBR e fana ka tekano ea ts'ebetso le moruo.

Litšebeliso tse tšoarellang nako e telele, tse thata, kapa tse bohlokoa bakeng sa polokeho: Tsetela ho FKM bakeng sa nako e fokotsehileng ea ho se sebetse le ho tšepahala ho hoholo.

5. Likotsi le Liphello tse Tloaelehileng

Ho sebelisa NBR ka mouoane kapa ozone: Ho baka ho thatafala, ho petsoha le ho dutla ha metsi ka mor'a libeke tse 'maloa.

Ho kenya EPDM liphaepheng tsa oli: Ho lebisa ho ruruha ha sekwahelo ka potlako, ho tshwarwa ha di-valve, le ho hloleha ha sistimi.

Ho kgetha FKM bakeng sa dikhase tse mocheso o tlase: E ka baka ho robeha ha dikhetla ka tlase ho -20°C ntle le dikereiti tsa mocheso o tlase.

6. Mekhoa ea Nakong e Tlang ea Theknoloji ea Litiiso​

Metswako e Tshebetso e Phahameng: Li-elastomer tse tletseng PTFE li ntlafatsa khanyetso ea lik'hemik'hale le mocheso ha li ntse li fokotsa khohlano.

Litiiso tse Bohlale: Li-sensor tse kentsoeng li hlahloba ho tsofala, khatello le mocheso, e leng se nolofalletsang tlhokomelo e boletsoeng esale pele.

Lisebelisoa tse Tšoarellang: Li-polymer tse thehiloeng ho bio le metsoako e ka sebelisoang hape li ntse li hohela liindasteri tse hlokomelang tikoloho.

Qetello​

Ho kgethwa ha thepa ha se tshebetso e lekanang tsohle empa ke ho hokahanya ka mokhoa o hlophisehileng thepa ya thepa le ditlhoko tsa tshebetso. Le hoja NBR e ipabola ditsamaisong tse thehilweng oling, FKM e mamella dikhemikhale tse matla le dithempereichara tse phahameng, mme EPDM ha e bapisoe le ditshebediso tsa metsi le mouoane. Ho utlwisisa dipharologanyo tsena—le ho sebedisa data ya botekgeniki ho tswa ho bafepedi—ho netefatsa tshebetso e ntle ya di-valve, ho fokotsa ditjeo tsa potoloho ya bophelo, le ho fokotsa dikotsi tsa tshebetso.

Sengoloa sena ke sa merero ea tlhahisoleseling. Kamehla sheba maqephe a data a tekheniki 'me u etse liteko tsa ho lumellana bakeng sa lits'ebetso tse itseng.
