Valve ea Heke ke eng
A valve ea hekee laola phallo ea mokelikeli ka ho phahamisa kapa ho theola heke (wedge) ka holimo. E etselitsoets'ebetso e felletseng ea ho bula/ho koala– ha e laole phallo – e fana ka khanyetso e fokolang ea phallo le ho tiisa ho phahameng. Kaha e sebelisoa haholo oli/khase, lifemeng tsa lik'hemik'hale le tlhahisong ea motlakase, ho tšepahala ha eona ho etsa hore e be ea bohlokoa bakeng sa litsamaiso tsa bekapo.
Molao-motheo oa ho Sebetsa oa Valve ea Heke
Heke e tsamaea ka ho otloloha ho ea phallong ea mokelikeli. Ha e phahamisitsoe ka botlalo, e lumella phallo e sa thibeloang; ha e theotsoe, e etsa tiiso e tiileng khahlanong le litulo tsa li-valve.Le ka mohla u se ke ua bula karolo e itsengli-valve tsa heke - sena se baka khoholeho ea seal le tšenyo ea ho thothomela.
Mehato e 5 ea Bohlokoa bakeng sa ho Boloka Li-valve tsa Heke
Polokelo e nepahetseng e thibela mafome mme e netefatsa hore di-valve tsa bekapo di sebetsa ha ho hlokahala.
1. Tikoloho e Loketseng ea Polokelo
–Ka tlung le ho oma: Boloka libakeng tse koetsoeng, tse nang le mongobo o tlase (<60% RH).
–Qoba Lintho Tse Senyang: Boloka hole le lik'hemik'hale, letsoai, kapa mosi o nang le asiti.
–Taolo ea Mocheso: Boloka mocheso o bataletseng oa 5°C–40°C (41°F–104°F).(Sheba tekanyetso ea ISO 5208: Mongobo o feteletseng o ka lebisa mafome likarolong tsa tšepe le ho tsofala ha litiiso tsa rabara.)
- Li-valve tse kholo le tse nyane li lokela ho bolokoa ka thoko:Li-valve tse nyane li ka beoa lishelefong, 'me li-valve tse kholo li lokela ho hlophisoa hantle fatše la ntlo ea polokelo, ha ho ntse ho netefatsoa hore bokaholimo ba khokahano ea flange ha bo ame fatše.
- Ho boloka di-valve kantle:U lokela ho etsa bonnete ba hore u li koahela ka lintho tse sa keneleng pula le tse sa keneleng lerole, tse kang tarpaulin, linoleum, jj. (Haeba maemo a lumela, ho khothaletsoa hore u se ke ua li boloka kantle)
Malebela:Boloka valve ea heke ka tlung 'me u boloke kamore e omme ebile e na le moea o kenang.
2. Tokisetso ea Valve
–Koala Heke: E thibela ho kena ha lerōle.
–Likou tsa Tiiso: Sebelisa likhaba tsa PVC kapa lipolaka tse koahetsoeng ka boka holim'a li-flange.
–Lubricate Likutu: Tlotsa mafura a boleng bo holimo holim'a likutu tse pepesitsoeng.
Malebela:Lipheletso ka bobeli tsa tsela li tlameha ho koaloa ka pampiri ea boka kapa maqephe a polasetiki ho thibela litšila ho kena.
3. Protokhole ea Polokelo ea Nako e Telele
–Litlhahlobo tsa Kotara le Kotara: Hlahloba mafome, botšepehi ba sekoahelo le setlolo.
–Potoloha Mabili a Matsoho: Phetla 90° likhoeli tse ling le tse ling tse 3 ho thibela ho tšoaroa ke eona.
–Litokomane: Li-valve tsa tag tse nang le letsatsi la polokelo le li-log tsa tlhahlobo.
- Kalafo ea ho thibela mafome:
1. Li-valve tsa tšepe (tse kang li-valve tsa heke le li-valve tsa ho emisa) li hloka ho tlotsoa ka oli e thibelang mafome kapa mafura, haholo-holo libaka tsa flange, manonyeletso a khoele le likarolo tse ling tse oxidized habonolo.
2. Ha e bolokiloe nako e telele (ho feta likhoeli tse 6), ho kgothaletswa ho hlahloba le ho eketsa sebolaya mafome ka dikgwedi tse 3 (ho latela maemo a API 598).
4. Valve ea Heke ea Tšepe e sa Cheseng le ea Khabone e Arohileng
- Kotsi ea ho Sila ha Galvanic:
1. Ho kopana + mongobo ho hlahisa sele ea electrochemical.
2. Tšepe ea khabone e fetoha anode, e bola ka potlako.
3. Tšepe e sa ruseng (cathode) e senyehile lera la eona le sireletsang le sa sebetseng, e leng se potlakisang ts'enyeho nakong e tlang.
- Ho falla ha Khabone (Carburization):
1. Ho kopana ka ho toba ho dumella diathomo tsa khabone ho tloha tshepeng ya khabone ho ya tshepeng e sa ruseng.
2. Sena se sitisa sebopeho sa tšepe e sa ruseng, se fokotsa haholo ho hanyetsa ha eona ho rusang.
- Mekhoa e Metle ea Polokelo:
1. Polokelo e Arohileng: Boloka libakeng tse fapaneng kamehla.
2. Sebaka se fokolang: Boloka bonyane sebaka sa 50 cm (20 inches), haholo-holo libakeng tse mongobo.
3. Ho kopana le metsi ka nakoana: Sebelisa lithibelo tse omileng, tse sa tsamaiseng motlakase (lehong, polasetiki, rabara) kapa lintho tse sireletsang.
5. Melao ea Bohlokoa bakeng sa Ntlafatso ea Polokelo ea Li-valve
- Tlhahlobo ea ho Khouta Mebala
• Li-valve tsa tšepe e sa ruseng → Theipi e putsoa
• Li-valve tsa tšepe ea khabone → Theipi e tšehla
E thibela liphoso tsa taolo ea pono le ho bola ha galvanic.
- Sebaka sa polokelo ea thepa sa FIFO
• Libaka tse khethehileng tsa polokelo li nolofalletsa ho potoloha ha pele ho ea pele ho tsoa
• E felisa ho siuoa ke nako ha setoko (e leng sa bohlokoa bakeng sa li-valve tsa bekapo)
- Karohano ea Tšireletso ea Litšenyehelo
• Arola li-valve tsa tšepe e sa ruseng (li bitsa makhetlo a 3-5 ho feta)
• E thibela tšebeliso e mpe ka phoso le tšenyo ea mafome
- Ho kenya tshebetsong Boenjiniere
• Tlhaloso ea Mokhoa
• Sebaka sa ho arola likarolo tse ka tlase ho ≥500mm
• Di-pad tsa rabara tse sa tsamaiseng motlakase tsa 8-10mm tse sa tsamaiseng motlakase
*Ho latela Melao: E fihlela maemo a GB/T 20878-2017.*
Malebela a Bohlokoa a Litsebi
• Mekhahlelo ea thepa e qhibilihisitsoeng ka laser (mohlala, “WCB”) mebeleng ea li-valve
• Boloka <45% RH libakeng tsa polokelo
• Li-valve tsa heke ea polokelo li eme li otlolohile - ho bokella ka ho rapama ho sitisa ho koaloa ha maemo a tšohanyetso
Papiso ea Mekhoa ea ho Boloka Li-valve tsa Heke ea Backup
Tlhokomelo ea Valve ea Heke: Mekhoa e 4 ea Bohlokoa
1. Tlhokomelo ea Ts'ebetso ea Kamehla
–Lubricate Likhoele: Tlotsa peista ea molybdenum disulfide ho linate tsa kutu ka kotara.
–Mantle a Hloekileng: Hlakola litšila/lithōle khoeli le khoeli ka masela a sa senyeheng.
–Hlahloba Mabili a Matsoho: Tiisa diboutu tse hlephileng hang-hang ho qoba ho se tsamaellane hantle.
2. Tlhokomelo ea ho Paka/Tšoelesa
–Hlahloba Kotara: Batla ho dutla ho potoloha kutu.
–Fetola Linate tsa Tšoelesa: Tiisa butle-butle haeba ho lla –u se ke ua hatella ho feta tekano.
–Nka Sebaka sa ho Paka: Sebelisa thapo e kentsweng ka graphite dilemo tse ding le tse ding tse 2-5.
3. Mekhoa e Metle ea ho Lubella
| Hlahisa | Tharollo |
| Ho tlotsa ka tlase ho setlolo | Kenya mafura ho fihlela a tsoa litiisong |
| Ho tlotsa ho feta tekano | Ema ha khanyetso e eketseha (max 3,000 PSI) |
| Grease e thatafetseng | Hlatsoa ka parafini pele o tlotsa hape |
4. Tlhokomelo ea Sistimi ea Phetisetso
–Mabokose a li-gearFetola oli selemo le selemo (e khothaletsoa ke ISO VG 220).
–Li-Actuator tsa Motlakase: Hlahloba litiiso tsa mongobo habeli ka selemo.
–Litlhaloso tsa letsoho: Etela khoeli le khoeli ho thibela ho tšoaroa ke sethoathoa.
Malebela a Ikhethang bakeng sa Li-valve tsa Backup
–Phomolo ea Khatello: Bula lipolaka tsa ho ntsha metsi pele o tlotsa ho thibela ho phatloha ha sekwahelo.
–Sebaka: Li-valve tsa heke ea polokeloe koetsoe ka botlaloho boloka litiiso li ntse li tšoarehile.
–Likiti tsa Maemo a Tšohanyetso: Boloka lisebelisoa tsa ho paka tse ling le linate tsa gland haufi.
Qetello: Ho Eketsa Nako ea Bophelo ea Valve
Latela melao ena bakeng sa li-valve tsa heke tse tšepahalang:
1. Polokelo= E omme, e koetsoe, 'me e ngotsoe.
2. Tlhokomelo= Ho tlotsa le ho hlahloba ka kemiso.
3. Litokiso= Lokisa ho dutla ha metsi hang-hang.
Ka ho beha tlhokomelo e potlakileng pele, o qoba 80% ea ho hloleha ha li-valve - e leng ea bohlokoa bakeng sa litsamaiso tsa maemo a tšohanyetso.
