Li-valve tsa metsing li bohlokoa bakeng sa ts'ebetso e bonolo ea likepe le liforomo tsa leoatle, ho netefatsa taolo ea mokelikeli, taolo ea khatello, le polokeho ea sistimi. Leha ho le joalo, ka lebaka la tikoloho e thata ea leoatle, li-valve tsena li ka ba le mathata a 'maloa a ka senyang ts'ebetso le polokeho. Ho utloisisa lintlha tsena tse tloaelehileng ke habohlokoa bakeng sa tlhokomelo ea thibelo le ho netefatsa hore ts'ebetso e tšepahala.
1. Ho Rua le ho Senyeha ha Lintho
Bothata:
Ho pepesehela metsi a letsoai le mocheso o feteletseng ho potlakisa ho bola, ho lebisang ho senyeha ha thepa le ho hloleha ha valve. Corrosion e ka fokolisa likarolo tsa li-valve, ea baka ho lutla le ho fokotsa nako ea bophelo ba tsona.
Tharollo:
- Sebelisa lisebelisoa tse thibelang ho bola joalo ka tšepe e sa hloekang, boronse kapa lialloys tse koahetsoeng ka ho khetheha.
- Etsa litlolo tse sireletsang 'me u hlahlobe khafetsa matšoao a pele a ho bola.
- Kenya ts'ebetso ea ts'ireletso ea cathodic ho fokotsa ho bola ho li-valve tse ka tlas'a metsi.
2. Leakage le Tiiso Ho hloleha
Bothata:
Ha nako e ntse e ea, li-seal le li-gaskets li ka senyeha, tse lebisang ho lutla. Khatello e phahameng, ho thothomela, le ho kenya ka mokhoa o sa lokelang ho mpefatsa taba ena. Ho lutla ho ka fella ka tahlehelo ea mokelikeli, likotsi tsa tikoloho, le ho se sebetse hantle ha tšebetso.
Tharollo:
- Hlahloba litiiso khafetsa 'me u li nkele sebaka e le karolo ea tlhokomelo ea kamehla.
- Sebelisa litiiso tsa boleng bo holimo, tsa boemo ba metsing le li-gaskets.
- Netefatsa hore li-valve li kentsoe ka nepo 'me li tiisitsoe ho latela lintlha tse khothaletsoang.
3. Li-blockages le ho koala
Bothata:
Li-valve tsa metsing li ka koaheloa ke maloanlahla, sediment le kholo ea leoatle, tsa thibela phallo ea mokelikeli le ho fokotsa ts'ebetso ea sistimi. Sena se atile haholo lits'ebetsong tsa ho noa metsi a leoatle.
Tharollo:
- Kenya li-strainers le li-filters holimo ho li-valve tsa bohlokoa ho tšoasa maloanlahla.
- Etsa ho hloekisa nako le nako ha valve le tsamaiso ea lipeipi.
- Sebelisa li-strainers tsa ho itlhoekisa libakeng tse atisang ho ba le tšoaetso e matla.
4. Mechini e Apehang le ho Khapha
Bothata:
Ts'ebetso e sa khaotseng, khatello e phahameng, le moferefere oa mokelikeli li baka ho roala ha mochini ho li-valve tsa kahare, tse lebisang ho fokotseng ts'ebetso le ho hloleha ho ka bang teng. Likarolo tse kang li-valve stems, litulo le li-discs li kotsing haholo.
Tharollo:
- Kenya tšebetsong kemiso ea ka mehla ea tokiso ho hlahloba le ho kenya likarolo tse tsofetseng.
- Sebelisa lisebelisoa tse sa senyeheng le liphahlo tse thata bakeng sa likarolo tsa bohlokoa.
- Lubribetsa likarolo tse tsamaeang khafetsa ho fokotsa likhohlano le ho senyeha.
5. Ts'ebetso e sa nepahalang ea Valve
Bothata:
Phoso ea motho, joalo ka boemo bo fosahetseng ba valve kapa ho tiisa ho feta tekano, e ka senya valve, e lebisang litabeng tsa ts'ebetso. Ho se lumellane ho ka boela ha etsahala nakong ea ho kenya.
Tharollo:
- Koetlisa basebetsi ka ts'ebetso e nepahetseng ea li-valve le mekhoa ea ho sebetsana le eona.
- Sebelisa li-valve tse ikemetseng kapa tse sebetsang hole le ho fokotsa liphoso tsa matsoho.
- Etsa tlhahlobo ea kamora ho kengoa ho netefatsa ho tsamaisana le tšebetso e nepahetseng.
6. Ho phahama ha Khatello le Hamore ea Metsi
Bothata:
Liphetoho tsa tšohanyetso tsa khatello, tse tsejoang e le hamore ea metsi, li ka senya li-valve tsa leoatleng, tsa baka mapetsong, ho senyeha, kapa ho falla ha tiiso. Sena se ka etsahala ha li-valve li koetsoe ka potlako haholo kapa haeba lipompo li koala ka tšohanyetso.
Tharollo:
- Kenya li-surge arrests le li-valve tse koalang butle ho laola liphetoho tsa khatello.
- Sebelisa liphaposi tsa moea kapa li-dampeners ho monya li-spikes tsa khatello ea tšohanyetso.
- Butle-butle li-valve li bula le ho koala ho thibela liphetoho tse potlakileng tsa khatello.
7. Valve Jamming kapa Sticking
Bothata:
Li-valve tsa metsing li ka 'na tsa jama kapa tsa khomarela ka lebaka la mafome, litšila kapa ho hloka mafura. Sena se ka thibela valve ho bula kapa ho koala ka botlalo, ho beha ts'ireletso ea sistimi kotsing.
Tharollo:
- Kamehla lubricate likarolo tsa valve ho thibela ho khomarela.
- Sebelisa li-valve nako le nako ho netefatsa hore li lula li sebetsa.
- Tlosa litlolo tse thibelang litšila ho thibela ho bokellana ha maloanlahla le mafome.
8. Calibration Drift
Bothata:
Ha nako e ntse e ea, li-valve tse hlokang ho lekanyetsoa hantle, joalo ka taolo ea khatello kapa li-valve tsa polokeho, li ka suthela kantle ho se boletsoeng, tsa senya ts'ebetso.
Tharollo:
- Rulahanya licheke tsa kamehla tsa calibration le ho lokisa li-valve ha ho hlokahala.
- Sebelisa li-valve tse nepahetseng haholo tse nang le ho hoholeha ho fokolang bakeng sa lits'ebetso tsa bohlokoa.
- Rekota lintlha tsa tlhophiso ho latela mekhoa ea ts'ebetso le ho tseba mathata a ka bang teng esale pele.
