Tsamaisong ea indasteri ea sejoale-joale, sistimi ea hydraulic e sebelisoa haholo masimong a fapaneng a kang mechini ea kaho, mechini ea merafo, le kaho ea likepe ka lebaka la melemo ea eona ea phetisetso ea motlakase e sebetsang hantle le e tsitsitseng. Valve ea brake, e le karolo ea bohlokoa ea sistimi ea hydraulic, ha e bohlokoa hakaalo.
1. Ho netefatsa polokeho ea ts'ebetso ea lisebelisoa
Hangata lisebelisoa tse tsamaisoang ke sistimi ea hydraulic li na le meroalo e meholo le lebelo le phahameng. Haeba kotsi e hlaha 'me braking e sa khone ho etsoa ka nako, ho ka etsahala hore e bake likotsi tse mpe tsa polokeho. Valve ea brake e ka fana ka matla a nepahetseng a braking maemong a tloaelehileng a ts'ebetso, e lumella lisebelisoa ho ema hantle ho latela sepheo sa mokhanni, ho qoba ho se sebetse hantle; maemong a tšohanyetso a kang ho hloleha ha motlakase, ka ho fetola valve ea brake ka lehlakoreng le ka pele le ho hokahanya le likarolo tse kang li-accumulators, e ka arabela kapele 'me ea finyella braking ea tšohanyetso. Mohlala, nakong ea ts'ebetso ea merafo, lisebelisoa tse kholo tse kang li-excavator li itšetleha ka valve ea brake ho ema ka nako haeba ho ka etsahala hore e hlolehe ka tšohanyetso, e thibele lisebelisoa ho thella kapa ho lahleheloa ke taolo, le ho netefatsa polokeho ea basebetsi le thepa ea lisebelisoa.
2. Ho netefatsa ts'ebetso e nepahetseng le e tsitsitseng
Ts'ebetso ea sistimi ea hydraulic e hloka taolo e nepahetseng, 'me litšobotsi tsa valve ea brake li ama ka ho toba ho nepahala le botsitso ba ts'ebetso. Sebopeho sa eona se kopaneng se e lumella ho kenngoa libakeng tse moqotetsane ntle le ho ama sebopeho se akaretsang sa sistimi ea hydraulic, 'me e ka boela ea sebelisana haufi-ufi le likarolo tse ling. Ho feta moo, e na le maikutlo a phutholohileng a leoto, karabelo e potlakileng ea khatello, le phetoho e boreleli, e lumellang basebetsi ho laola matla a brake ka nepo ho latela maemo a sebele a ts'ebetso. Nka mohlala oa crane mechini ea kaho. Nakong ea ts'ebetso ea ho phahamisa, valve ea brake e ka emisa letsoho la ho phahamisa ka nepo sebakeng se khethiloeng, e qoba ho se tsitse ha brake ho ka etsang hore ntho e boima e sisinyehe kapa e be e oa, e ntlafatsa boleng ba ts'ebetso le katleho.
3. Ho ikamahanya le maemo le maemo a fapaneng a mosebetsi
Litsamaiso tsa haeteroliki liindastering tse fapaneng li tobana le maemo le maemo a fapaneng a mosebetsi. Litekanyetso tsa ts'ebetso ea valve ea brake li khetholla ho ikamahanya ha eona. Tafole e latelang e bonts'a li-parameter tsa bohlokoa tsa valve ea brake le maemo a tsamaellanang a ho ikamahanya le maemo:
| Mofuta oa Paramethara | Liparamente tse Ikhethang | Maemo a ho Ikamahanya le Maemo |
| Mokhoa o Sebetsang | Oli ea Hydraulic e thehiloeng ho Mineral | E koahela boholo ba litsamaiso tsa hydraulic tsa indasteri 'me e lumellana hantle. |
| Sebaka sa ho thothomela | 2.8 – 380mm²/s | E ka sebetsa ka botsitso maemong a kang a batang kantle libakeng tse ka leboea (tlhoko e tlase ea viscosity) le li-workshop tsa indasteri tse nang le mocheso o phahameng (tlhoko e phahameng ea viscosity). |
| Mocheso oa Oli ea Haeteroliki | - 30℃ ho isa ho 107℃ | E ikamahanya le maemo a fapaneng a rarahaneng a mosebetsi ho tloha ho batang haholo ho isa ho mocheso o phahameng. |
| Khatello ea ho Beha Khatello | 20 – 200bar | E fihlela litlhoko tsa ho thiba meroalo le matla a fapaneng, ho tloha ho thiba braking e nyane ea lisebelisoa tse bobebe ho isa ho thiba braking e matla ea mechini e boima. |
| Khatello e Phahameng ea ho Kena ea Letoto Lohle | Libara tse 210 | E fana ka tšehetso e lekaneng ea matla a ho brake bakeng sa litsamaiso tsa hydraulic tse nang le litlhoko tse phahameng tsa khatello. |
4. Ntlafatsa botšepehi le bophelo ba tšebeletso ea sistimi
Valve ea brake e na le litlhoko tse tiileng tsa bohloeki (e fihla maemong a 18/16/13, ISO4406), 'me hape e fokotsa khatello e phahameng ka ho fetisisa ea oli e khutlang ho feta bareng e le' ngoe. Sena se thusa ho boloka bohloeki le botsitso ba sistimi ea hydraulic. Tikoloho e hloekileng ea sistimi e fokotsa ho tsofala ha likarolo tsa hydraulic ke litšila, 'me khatello e tsitsitseng ea oli e khutlang e qoba ho tšoha tsamaisong e bakoang ke ho feto-fetoha ha khatello, ka hona e fokotsa sekhahla sa ho hloleha ha sistimi eohle ea hydraulic, e eketsa bophelo ba ts'ebeletso ea lisebelisoa, e fokotsa litšenyehelo tsa tlhokomelo ea khoebo le nako ea ho se sebetse, le ho netefatsa tsoelo-pele ea tlhahiso.
Valve ea brake e bapala karolo ea bohlokoa tsamaisong ea hydraulic mabapi le netefatso ea polokeho, taolo ea ts'ebetso, ho ikamahanya le tikoloho le ts'epo ea sistimi. Ke karolo ea bohlokoa ea bohlokoa bakeng sa ts'ebetso e tsitsitseng, e sebetsang hantle le e sireletsehileng ea sistimi ea hydraulic. Ka nts'etsopele e tsoelang pele ea theknoloji ea indasteri, litlhoko tsa ts'ebetso ea valve ea brake le tsona li tla tsoela pele ho eketseha. Valve ea brake le eona e tla lula e qaptjoa le ho ntlafatsoa, e fana ka tšehetso e matla haholoanyane bakeng sa nts'etsopele ea sistimi ea hydraulic.
