Li-valve tse Laolang Mocheso o Phahameng o Tiisitsoeng li Ntlafatsa Sebetsa sa Mouoane ka Matla
Li-valve tse Laolang Mocheso o Phahameng o Tiisitsoeng li Ntlafatsa Sebetsa sa Mouoane ka Matla
I. Molao-motheo oa ho sebetsa oa mocheso o phahameng o tiisitsoeng valve e laolang
Molao-motheo o sebetsang oa mocheso o phahameng o tiisitsoebelofo e laolange tšoana le li-valve tse ling tsa pneumatic regulating, empa e ikhethang e itšetlehile ka thepa e hanyetsanang le mocheso o phahameng le moralo o khethehileng. Ha moea o hatelitsoeng o kena ho actuator, kutu ea valve e khannoa ka converter ea metsi a khase kapa ka ho toba ka cylinder ho laola motsamao oa motheo oa valve. Ho sisinyeha ha mokokotlo oa valve ho fetola boholo ba mocha oa phallo ea mouoane, kahoo ho finyella taolo e nepahetseng ea phallo ea mouoane.
II. Likarolo tsa sebopeho
1. Lisebelisoa tsa mocheso o phahameng: 'Mele oa valve le likarolo tse ka hare li entsoe ka thepa e khonang ho mamella mocheso o phahameng, joalo ka tšepe e sa hloekang, li-alloys tse khethehileng, joalo-joalo.
2. Sebopeho sa ho tiisa: Setulo sa valve le mokokotlo oa li-valve li entsoe ka thepa e phahameng ea mocheso le e sa senyeheng ho netefatsa ts'ebetso e ntle ea ho tiisa mocheso o phahameng.
3. Tšireletso ea tšireletso: Li-valve tse ling tse laolang mocheso o phahameng oa mocheso li na le lisebelisoa tsa tšireletso tse kang tšireletso e feteletseng le tšireletso ea khatello ho thibela likotsi.
III. Sebaka sa kopo
Mocheso o phahameng o tiisitsoeng li-valve tse laolang li sebelisoa haholo liindastering tse hlokang ho sebetsana le mocheso o phahameng oa mocheso, joalo ka petrochemical, matla a motlakase, metallurgy, papermaking, joalo-joalo Hangata li sebelisoa ka marang-rang a liphaephe tsa mouoane, li-turbine tsa mouoane, lijenereithara tsa mouoane, lihlahisoa tsa mocheso le tse ling. lisebelisoa ho fihlela taolo ea phallo ea mouoane.
IV. Melemo ea tekheniki
1. Ho hanyetsa mocheso o phahameng: E ka sebetsa ka mokhoa o tsitsitseng mocheso o phahameng kapa esita le tikoloho ea mocheso o phahameng haholo ho finyella litlhoko tsa mefuta e sa tšoaneng ea liindasteri.
2. Taolo e nepahetseng: Ka mekhoa e tsoetseng pele ea taolo le theknoloji ea ho beha maemo, e ka finyella taolo e nepahetseng ea ho phalla ha mouoane o phahameng oa mocheso.
3. Ho tšepahala ho phahameng: Tšebeliso ea lisebelisoa tsa boleng bo phahameng le mekhoa e tsoetseng pele ea tlhahiso e etsa bonnete ba hore ts'ebetso e tsitsitseng ea nako e telele ea valve sebakeng sa mocheso o phahameng.
V. Paballo le tlhokomelo
E le ho eketsa bophelo ba tšebeletso ea valve e laolang mocheso o phahameng oa mocheso, ho hlokahala hore u qale ho tloha likarolong tse latelang:
1. Ho kenngwa ka nepo: Netefatsa bohlweki ba phaepe ho qoba ditshila tse thibelang kapa ho thiba karolo ya throttle kapa tataiso.
2. Tšebeliso e utloahalang: Tlas'a motheo oa ho finyella litlhoko tsa ts'ebetso, tlohela valve e laolang hore e sebetse sebakeng se phahameng sa ho bula ho fokotsa ho senyeha.
3. Taolo ea tikoloho: Qoba ts'ebetso ea nako e telele ea valve e laolang mocheso o phahameng, khatello e phahameng kapa mocheso le ho fetoha ha khatello. Haeba ho hlokahala, nka mehato e kang ho boloka mocheso, ho thibela mocheso, ho pholisa, le ho tsitsisa khatello.
VI. Tlhahlobo ea nyeoe
Nka mohlala oa tsamaiso ea turbine ea mouoane ea k'hamphani e itseng ea matla. Tsamaiso e hloka ho sebetsa ka mokhoa o tsitsitseng tlas'a mocheso o phahameng le maemo a khatello e phahameng. Ka ho hlahisa valve e laolang mocheso o phahameng o tiisitsoeng, eseng feela taolo e nepahetseng ea phallo ea mouoane e finyelloang, empa hape le katleho ea kakaretso le polokeho ea tsamaiso e ntlafatsoa haholo. Kamora nako ea ts'ebetso, katleho ea tlhahiso ea k'hamphani e eketsehile ka 15% mme sekhahla sa ho hloleha ha lisebelisoa se theohile ka 30%.
Tšebeliso ea li-valve tse laolang tse nang le mocheso o phahameng oa mocheso tsamaisong ea mouoane oa mocheso o phahameng ha e ntlafatse feela ts'ebetso ea ts'ebetso le polokeho ea tsamaiso, empa hape e fana ka liphallelo tsa bohlokoa ho boloka matla, ho fokotsa mocheso le nts'etsopele e tsitsitseng ea likhoebo. Ka tsoelo-pele e tsoelang pele ea theknoloji ea indasteri, li-valve tse laolang tse tiisitsoeng ka mocheso o phahameng li tla bontša boleng ba tsona bo ikhethang le litebello tse pharaletseng tsa ts'ebeliso libakeng tse ngata.
Ka kutloisiso e tebileng le ts'ebeliso e sebetsang ea li-valve tsa taolo tse tiisitsoeng tsa mocheso o phahameng, likhoebo li ka ntlafatsa lits'ebetso tsa tlhahiso hamolemo, tsa ntlafatsa boleng ba sehlahisoa, le ho fokotsa litšenyehelo tsa ts'ebetso, ka hona tsa ba maemong a matle tlholisanong e matla ea 'maraka.
