Mesebetsi ea Bohlokoa le Melao-motheo ea Ts'ebetso ea Li-cylinder tsa Hydraulic Litsamaisong tsa Kajeno
Kamoo Li-cylinder tsa Hydraulic li Sebetsang Kateng
Silindara ea hydraulic ke sesebelisoa sa ho susumetsa litsamaisong tsa hydraulic. E fetola matla a hydraulic hore e be matla a mechini bakeng sa motsamao o otlolohileng. Molao-motheo oa ho sebetsa o latela molao oa Pascal. Khatello ea oli ea hydraulic e sutumelletsa piston ka har'a tube ea silindara.
Mokhoa oa ho Sebetsa:
- Kenyelletso ea Oli: Pompo ea hydraulic e romela oli ka har'a tube ea silindara
- Motsamao oa Piston: Tlas'a khatello, piston e sutumelletsa mojaro ka mola o otlolohileng
- Setoroko sa ho Khutlela: Kamora ho fihla boemong, oli e phalla hape ho phethela potoloho.
Moralo ona o bonolo o fana ka matla a matla a tlhahiso. Silindara ea hydraulic e ka sebetsana le meroalo e boima ka taolo e nepahetseng.
Libaka tse ka Sehloohong tsa Kopo:
Lisilindara tsa haeteroliki li sebeletsa liindasteri tse ngata. Li fana ka matla a maholo a ho sutumelletsa mechine e hlokang motsamao o otlolohileng. Libaka tsa bohlokoa li kenyelletsa:
- Mechine ea haeteroliki bakeng sa ho etsa tšepe
- Mechini ea kaho e kang ea ho epa
- Lisebelisoa tsa tšepe
- Mechini ea ho enta ka ente
- Mekhoa ea tlhahiso
Mofuta o mong le o mong oa silindara ea hydraulic o fana ka mefuta e fapaneng ea matla. Baenjiniere ba khetha ho latela litlhoko tsa mojaro le moralo oa sistimi.
Liphapang tsa Bophara ba Boro le Tšusumetso ea Tsona Tshebetsong ea Matla a Tsoang ho Silindara
Kamano Pakeng tsa Bore le Matla
Bophara ba mokoti bo khetholla matla a tlhahiso ea silindara ea hydraulic. Mokoti o moholo o hlahisa matla a mangata. Foromo e bonolo:
Moo:
- F= Matla a khopolo-taba (Newtons)
- D= Bophara ba mokoti (mm)
- P= Kgatelelo ya sistimi (MPa)
Mefuta ea Boholo ba Bore:
Boholo bo fapaneng ba li-bore bo phetha merero e fapaneng:
| Mofuta oa Bore | Bophara | Melemo | Meeli | Likopo |
|---|---|---|---|---|
| Bore e Nyenyane | 50-80mm | Moralo o monyane, theko e tlase, karabelo e potlakileng | Matla a fokolang a hlahisoang | Lisebelisoa tse nepahetseng, libaka tse patisaneng |
| Bore e Mahareng | 100-160mm | Matla le lebelo tse leka-lekaneng, tse tenyetsehang | E hloka litsamaiso tsa khatello e mahareng | Mechine e akaretsang ea hydraulic, mechine |
| Bore e Kholo | 200mm+ | Matla a maholo, ts'ebetso e tsitsitseng | Boholo bo boholo, theko e phahameng, bo hloka khatello e phahameng | Likhatiso tse boima, lisebelisoa tsa tšepe |
Bophara ba Piston Rod le bona boa ba bohlokoa
Bophara ba thupa ea piston hangata ke 30% ho isa ho 70% ea boholo ba mokoti. Thupa e teteaneng e hanela ho kobeha hamolemo. Sena se bohlokoa bakeng sa ho kobeha ho hole kapa meroalo e ka thoko. Bakeng sa ho kobeha ho fetang limithara tse 1.5, moralo o thibelang ho kobeha oa hlokahala. Ntle le moralo o nepahetseng, thupa e ka 'na ea kobeha tlas'a mojaro.
Ha o kgetha silindara ya hydraulic, nahana ka boholo ba mokoti le thupa. Motswako o nepahetseng o netefatsa tshebetso e tshepahalang le bophelo bo bolelele ba tshebeletso.
Tataiso ea Khetho ea Thepa bakeng sa Li-Tube tsa Silindara, Lithupa tsa Piston, le Likarolo tsa Bohlokoa
Lisebelisoa tsa Tube ea Silindara
Tube ea silindara e tšoara oli ea hydraulic 'me e tataisa piston. Khetho ea thepa e itšetlehile ka khatello le tikoloho:
| Thepa | Matlo | Tekanyetso ea Khatello | Lintlha |
|---|---|---|---|
| #20 Tšepe e se nang seamless | Khabone e tlase, ho tjheseletsa hantle, theko e tlase | Tlase (≤10MPa) | E hloka ho holisoa ho fihlela ho Ra ≤0.4μm |
| #35 Tšepe e se nang seamless | Khabone e mahareng, matla a leka-lekaneng | Bohareng (10-20MPa) | Tshebetso e ntle ka kakaretso |

Bakeng sa boholo ba lits'ebetso tsa silindara ea hydraulic, tšepe e se nang seamless #45 e fana ka boleng bo botle ka ho fetisisa. E sebetsana le khatello e phahameng 'me e hanela ho tsofala.
Lisebelisoa tsa Piston Rod
Thupa ea piston e hokahana le mojaro. E tlameha ho hanela ho kobeha le ho tsofala:
| Thepa | Kalafo | Bothata | Likopo |
|---|---|---|---|

Lisilindara tsa hydraulic li sebetsa e le li-actuator tsa bohlokoa indastering ea sejoale-joale. Li fetola matla a mokelikeli hore e be motsamao o tšepahalang oa mola o otlolohileng. Bophara ba mokoti bo ama ka ho toba matla a tlhahiso, ka li-bore tse kholo tse hlahisang matla a ho sutumelletsa a mangata. Khetho ea thepa e khetholla ho tšoarella ha silindara le ts'ebetso. Li-tube tsa silindara hangata li sebelisa tšepe e se nang sekoli ea #45 bakeng sa lits'ebetso tse nang le khatello e phahameng. Lithupa tsa piston li hloka kalafo ea bokaholimo joalo ka ho penta ka chrome bakeng sa ho hanyetsa ho tsofala. Baenjiniere ba tlameha ho leka-lekanya litlhoko tsa matla, maemo a tikoloho, le litšenyehelo ha ba khetha silindara ea hydraulic. Ka ho utloisisa litlamorao tsa mokoti le thepa ea thepa, basebelisi ba ka khetha silindara e nepahetseng bakeng sa ts'ebeliso e 'ngoe le e 'ngoe. Sena se netefatsa bophelo bo bolelele ba ts'ebeletso le ts'ebetso e ntle ho pholletsa le likhatiso tsa hydraulic, lisebelisoa tsa kaho le litsamaiso tsa tlhahiso.
