Liindastering tse boima tse kang merafo, ho kenya le ho theola thepa koung, le mechini ea kaho, li-winches tsa hydraulic, ka matla a tsona a matla a ho hula le ts'ebetso e tsitsitseng ea ts'ebetso, li fetohile lisebelisoa tsa bohlokoa bakeng sa ts'ebetso ea ho phahamisa le ho hula thepa. Leha ho le joalo, litsebi tse ngata tsa indasteri li tla fumana hore li-winches tsa hydraulic li hloka yuniti ea matla a hydraulic (HPU) bakeng sa ts'ebetso e nepahetseng. Ke eng e bakang "tšebelisano-'moho ena ea khauta"? Hobaneng HPU e fetoha "pelo" le "boko" ba winch ea hydraulic?
I. HPU: "Mohloli oa Matla" oa Winch ea Hydraulic, e nolofalletsang Phetoho e Nepahetseng ea Matla
Karolo ea bohlokoa ea ts'ebetso ea winch ea hydraulic ke enjene ea hydraulic, e itšetlehileng ka oli ea khatello e phahameng ho sebetsa—mohloli ona oa bohlokoa oa motlakase o fanoa ke HPU. Ts'ebetsong ea 'nete, HPU e sebelisa enjene ea motlakase kapa enjene ea diesel ho khanna pompo ea hydraulic, e fetolelang matla a motlakase kapa a mechini ka katleho hore e be matla a hydraulic. Matla ana ebe a tsamaisoa e le oli ea khatello e phahameng ka liphaephe ho ea ho enjene ea hydraulic ea winch ea hydraulic. “Ntle le HPU, winch ea hydraulic e tšoana le koloi e se nang motlakase—e ke ke ea qala,” ho hlalositse Monghali Li, moenjiniere k'hamphaning ea tlhahiso ea mechini e boima. “Maemo a fapaneng a ts'ebetso a hloka matla a fapaneng a ho hula. HPU e ka fetola khatello ea tlhahiso ea pompo ea hydraulic ho lekana matla a ho hula a winch ea hydraulic ho tloha ho mashome ho isa ho makholo a likilonewton, e fihlela litlhoko tse fapaneng tsa kaho ea merafo, koung le borokho.”
II. Taolo e Nepahetseng: "Boko": HPU e Etsa Hore Ts'ebetso ea Winch e Tenyetsehe le ho Laoleha Haholoanyane
Ntle le ho fana ka motlakase, HPU e boetse e sebetsa e le "setsi sa taolo" sa winch ea hydraulic. Ka har'a sistimi e kopaneng ea HPU, li-valve tse fapaneng tsa taolo, ho kenyeletsoa li-valve tsa khatello, li-valve tsa phallo, le li-valve tse tataisang, li sebetsa 'moho ho laola khatello, sekhahla sa phallo, le tataiso ea oli ea hydraulic ka nepo—ntlha ea bohlokoa e khethollang ka ho toba lebelo la ts'ebetso ea winch ea hydraulic, tataiso ea ho hula, le ho nepahala ha ts'ebetso. Mohlala, nakong ea ts'ebetso ea ho kenya le ho theola lijana likoung, valve ea phallo ea HPU e lumella li-winches tsa hydraulic ho phahamisa le ho theola thapo ea terata butle-butle, ho thibela tšenyo ea lijana tse bakoang ke ho thulana. Nakong ea ts'ebetso ea ho hula cable ea borokho, valve ea khatello ea HPU e lekola khatello ea sistimi ka nako ea sebele, e netefatsa hore matla a ho hula a lula a le sebakeng se sireletsehileng le ho thibela ho jara cable le ho robeha. Motsamaisi oa ts'ebetso ea koung o itse, "Ka lebaka la taolo e nepahetseng ea HPU, katleho ea ts'ebetso ea winch ea hydraulic e eketsehile ka 20% ha e ntse e fokotsa sekhahla sa ho hloleha ha lisebelisoa ka 15%.
III. Ho netefatsa botsitso ba sistimi: Li-winches tsa Hydraulic tsa "Guards" tsa HPU
Ts'ebetso e tsitsitseng ea litsamaiso tsa hydraulic e itšetlehile ka oli e hloekileng le mocheso o loketseng oa ts'ebetso - mosebetsi o mong oa mantlha oa HPU. Moqolotsi oa litaba o hlokometse setsing sa tlhahiso ea mechini ea kaho hore HPU e tloaelehileng hangata e kopanya likarolo tse thusang tse kang tanka ea oli, sefe ea oli le sehatsetsi. Tanka ea oli e boloka oli e lekaneng bakeng sa sistimi mme e boetse e sebeletsa ho thibela litšila. Sefe ea oli e nepahetseng haholo e tlosa litšila tse kang lerōle le lithōle tsa tšepe ho tsoa oli, e thibela ho tsofala ha likarolo tse nepahetseng tse kang li-motor tsa hydraulic le li-valve. Sehatsetsi se fokotsa mocheso oa oli ka katleho, se thibela mocheso o feteletseng oa oli ho baka phokotso ea viscosity ea oli ea hydraulic le khatello e sa tsitsang ea sistimi.
“Likarolo tsa haeteroliki li hloka bohloeki bo phahameng haholo ba oli. Esita le litšila tse boholo ba micron li ka baka ho khomarela ha valve le ho senyeha ha enjene,” ho hlalositse Moenjiniere Li, a supa kopano ea sefe ea HPU. “Mesebetsi ea ho hloekisa oli le taolo ea mocheso ea HPU e eketsa bophelo ba winch ea hydraulic, e fokotsa nako ea ho se sebetse ha tlhokomelo, le ho fokotsa litšenyehelo tsa ts'ebetso ea k'hamphani.”
IV. Tšireletso ea Polokeho “Tšitiso”: HPU e matlafatsa polokeho ea ts'ebetso.
Mesebetsing e kotsi haholo, mesebetsi ea tšireletso ea polokeho ea HPU e bohlokoa le ho feta. Hona joale, li-HPU tse tloaelehileng kaofela li kopanya lisebelisoa tsa polokeho tse kang li-valve tsa tšireletso ea overload le li-valve tsa brake tsa tšohanyetso. Ha khatello ea sistimi ea winch ea hydraulic e feta boleng bo behiloeng ka lebaka la mojaro o feteletseng, valve ea tšireletso ea overload e buleha ka bo eona ho lokolla khatello e feteletseng, e thibela tšenyo ho enjene ea hydraulic le thapo ea terata. Maemong a tšohanyetso a kang ho tima ha motlakase ka tšohanyetso kapa ho phatloha ha liphaephe, valve ea brake ea tšohanyetso ea HPU e khaola phepelo ea oli hang-hang, e etsa hore winch ea hydraulic e eme ka ho feletseng, e thibele likotsi tse kang lintho tse boima tse oang kapa tse thellang.
Tšobotsi ena ea polokeho e bohlokoa haholo mesebetsing ea merafo ea ka tlas'a lefatše. Ofisiri ea polokeho ea morafo e boleletse baqolotsi ba litaba, "Sebaka sa ho sebetsa ka tlas'a lefatše se koetsoe, 'me ho hloleha ha winch ea hydraulic ho tla ba le liphello tse mpe. Sistimi ea tšireletso ea polokeho ea HPU e sebetsa joalo ka 'valve ea polokeho,' khafetsa e thibela likotsi tsa polokeho tse bakoang ke ho jara lisebelisoa ka bongata."
V. Ho Ikamahanya le Maemo a Fapaneng a Mosebetsi: Li-HPU li Etsa Hore Li-Winches tsa Hydraulic li “Bohle”
Maemo a tikoloho maemong a fapaneng a ts'ebetso a fapana haholo, 'me moralo o tenyetsehang oa HPU o nolofalletsa li-winches tsa hydraulic ho sebetsa ka katleho maemong a fapaneng a rarahaneng a ts'ebetso. Bakeng sa lifeme le likou tse nang le phepelo ea motlakase e tsitsitseng, li-HPU tse tsamaisoang ka motlakase ke khetho e khethiloeng ka lebaka la lerata la tsona le tlase le ho se be le mosi o tsoang. Bakeng sa libaka tse kantle ho gridi joalo ka lipatlisiso tsa masimo le merafo e bulehileng, li-HPU tse tsamaisoang ka diesel li ka fana ka matla a tsoelang pele ho li-winches tsa hydraulic li sebelisa mohloli oa tsona oa motlakase.
Li-HPU li ka boela tsa fetoloa ho latela lintlha tse kang mocheso oa tikoloho ea ts'ebetso, mongobo le bongata ba lerōle. Mohlala, libakeng tse batang, li-HPU li na le li-heater tsa oli ho thibela ho hoama ha oli mochesong o tlase; libakeng tse mongobo tsa lebopong, likarolo tsa tšepe tsa HPU li koahetsoe ka sekoahelo se thibelang ho hoama ho ntlafatsa ho hanyetsa ho hoama. Ho ikamahanya le maemo hona ho phahameng ho etsa hore li-winches tsa hydraulic li sebelisoe haholo maemong a fapaneng, ho kenyeletsoa le naheng, leoatleng le libakeng tse phahameng.
Qeto: Li-HPU le li-winch tsa hydraulic li theha "motheo oa matla" oa ts'ebetso ea indasteri.
Ho tloha phepelong ea motlakase ho isa taolong e nepahetseng, ho tloha botsitsong ba sistimi ho isa ts'ireletsong ea polokeho, HPU, ka mesebetsi ea eona e mengata ea mantlha, e fetohile molekane oa bohlokoa bakeng sa li-winches tsa hydraulic. Ka tsoelo-pele ea boiketsetso ba indasteri le bohlale, li-HPU le tsona li ntse li ntlafatsoa khafetsa. Kajeno, li-HPU tse bohlale tse kopantsoeng le theknoloji ea IoT li nolofalletsa tlhokomelo e hole le litemoso tsa liphoso, li ntlafatsa haholoanyane bokhoni le ts'epo ea li-winches tsa hydraulic.
Litsebi tsa indasteri li bontša hore nts'etsopele ea tšebelisano-'moho ea li-HPU le li-winch tsa hydraulic nakong e tlang e tla hatisa haholo paballo ea matla, tšireletso ea tikoloho le bohlale, e fane ka tšehetso e matla bakeng sa phetoho e tala le tlhahiso e sebetsang hantle lefapheng la indasteri e boima. Ho utloisisa mohopolo oa tekheniki o ka morao ho "tšebelisano-'moho ena ea khauta" ho tla boela ho thuse basebetsi ba bangata ba indasteri ho sebelisa lisebelisoa hamolemo le ho ntlafatsa katleho ea ts'ebetso.
