Ezindaweni zokusebenza zanamuhla, amasistimu e-hydraulic ayisisekelo semisebenzi eminingi, enika amandla konke kusukela emishinini yokwakha enzima kuya emishinini yokukhiqiza enembile. Ukusebenza kahle kwesistimu ye-hydraulic kunquma ngqo ukuthi amandla emishini adluliswa, alawulwe, futhi asetshenziswe kanjani ngempumelelo kulo lonke uhlelo lokusebenza. Lapho isistimu isebenza ngokusebenza kahle okuphezulu, idla amandla amancane, ikhiqiza ukushisa okuncane, futhi iletha umphumela ongaguquki ngaphansi kwezimo zomthwalo ezihlukahlukene. Ngokuphambene, noma ukwehla okuncane ekusebenzeni kahle kwesistimu ye-hydraulic kungaholela ezindlekweni zokusebenza eziphakeme, isikhathi sokungasebenzi esingahleliwe, kanye nokuguga okusheshayo ezingxenyeni ezibalulekile. Kubaphathi bezikhungo kanye namathimba okulungisa, ukuqonda ubudlelwano phakathi kokunakekelwa okuvamile nokwethembeka kwesikhathi eside akulona ilungelo — kuyisidingo esiyisisekelo sokukhiqiza okuqhubekayo. Izindlela zokulungisa ezisebenzayo ezibhekana nesimo soketshezi, ubuqotho bezingxenye, kanye nemingcele yokusebenza zakha isisekelo sanoma yiluphi uhlelo oluphumelelayo lokuthuthukisa ukusebenza kahle. Lesi sihloko sihlola izici eziyinhloko ezilimaza ukusebenza futhi sinikeze amathiphu okulungisa asebenzayo angasiza amabhizinisi ukuthi athole ukwethembeka kwesistimu ye-hydraulic okuhlala isikhathi eside ngenkathi kuncishiswa izindleko eziphelele zobunikazi.

Izinto eziningana ezihlangene zinomthelela ekwehleni kancane kancane kokusebenza kahle kohlelo lwe-hydraulic, futhi ukuzibona kusenesikhathi kubalulekile ukuze kungenelelwe ngempumelelo. Ukungcola koketshezi kuseyingozi enkulu kunazo zonke, njengoba izinhlayiya ezincane ezivela emfucumfucwini wokugqokwa, ukungcola okungenile, kanye nemikhiqizo yokonakala koketshezi zijikeleza emavulvini, emaphompini, nasezintweni ezisebenzayo, zibangele ukuguguleka nokukhathala kwendawo. Ngokuhamba kwesikhathi, lokhu kungcola kwandisa ukuvuza kwangaphakathi, kunciphisa ukusebenza kahle kwevolumu, futhi kukhuphule amazinga okushisa okusebenza, okusheshisa ukonakala koketshezi. Ukuvuza kwama-seal, noma ngabe kwangaphandle noma kwangaphakathi, kungomunye umthombo omkhulu wokulahlekelwa ukusebenza kahle — noma ukuvuza okuncane kungavumela umoya ukuba ungene, okuholele ekwakhekeni kwemigodi, ukugqwala, nokuncipha kokuqina kohlelo. Izilungiselelo ezingafanele zomfutho, noma ngabe ziphezulu kakhulu noma ziphansi kakhulu, ziphoqa izingxenye ukuba zisebenze ngaphandle kwemikhawulo yazo yokuklanywa, zimose amandla futhi zinciphise isikhathi sokusebenza. Ukushisa ngokweqile, okuvame ukubangelwa ukupholisa okunganele noma ukungqubuzana okweqile, kunciphisa ukujiya koketshezi lwe-hydraulic, kunciphisa amandla wefilimu yokugcoba, futhi kukhuthaze ukugqwala, kudale umjikelezo olimazayo wempendulo. Ukwengeza, ukonakala koketshezi ngenxa yengcindezi yokushisa, ukungcola kwamanzi, nokonakala kwamakhemikhali kushintsha i-viscosity kawoyela kanye nephakheji yezithako, kubeke engcupheni kokubili ukugcoba nokuvikela. Ngayinye yalezi zinkinga, uma ingalungiswa, ihlanganisa nezinye, okwenza ukuthi ukuthuthukiswa kokusebenza kahle kohlelo kube umsebenzi oqhubekayo hhayi owesikhathi esisodwa.

Ukuqalisa uhlelo olunzima lokuhlaziya uketshezi kungenzeka kube yisinyathelo esinomthelela omkhulu kunazo zonke iqembu noma yiliphi elinakekela elingalithatha ukuze ligcine ukusebenza kahle kohlelo lwe-hydraulic futhi landise impilo yezingxenye. Ngokuthatha amasampula ngezikhathi ezithile kawoyela we-hydraulic nokuhlola inani lezinhlayiya, ukujiya, umswakama, inani le-asidi, nezinsimbi ezigqokile eziyisisekelo, ochwepheshe bathola umfanekiso ocacile wempilo yoketshezi kanye nesimo somshini. Le datha inika amandla izinqumo zokunakekela ezisekelwe esimweni, okuvumela izihlungi ukuthi zishintshwe ngokusekelwe esidingweni sangempela kunasezinhlelweni ezingahleliwe. Izinhlelo zokuhlunga ezisezingeni eliphezulu, okuhlanganisa izihlungi zomugqa wokucindezela kanye nezomugqa wokubuyisela ezinamazinga afanele e-micron, zibalulekile ekugcineni amazinga okuhlanzeka koketshezi ahlangabezana nezincomo ze-OEM. Ezimweni eziningi, ukuthuthela ezingeni lokuhlunga elihle kakhulu noma ukwengeza ukuhlunga kwe-kidney-loop okungaxhunyiwe kunganciphisa kakhulu ukugqoka okubangelwa ukungcola futhi kuthuthukise ukusebenza kahle kohlelo lonke. Emisebenzini esebenzisa amaphampu e-piston aguquguqukayo noma amavalvu e-servo-proportional, lapho izikhala zixine kakhulu, ukuhlanzeka kuba kubaluleke nakakhulu. Ukuhlanganisa ukuthatha amasampula okuvamile nokuhlunga okulungisayo kuqinisekisa ukuthi uketshezi luhlala luyindlela ethembekile yokudlulisa amandla kunokuba lube ngumthwali wezinhlayiya ezonakalisayo.

Ukusungula uhlelo oluhleliwe lokuhlola amahose, izivalo, nezingxenye ezishintshwayo kungavimbela ukwehla okuncane ekukhuleni kube yizinkinga ezinkulu ezingaphazamisa ukwethembeka kohlelo lwe-hydraulic. Amahose kufanele ahlolwe ukuthi awona yini, aqhekekile, anamabhamuza, noma ukugqwala kwe-fitting, njengoba noma yimuphi umonakalo wangaphandle ukhombisa ukuwohloka kwangaphakathi okuqinisa okungaholela ekuqhekekeni maduze. Izivalo ezisezintini zama-cylinder, emishinini yamaphampu, nasezintini zamavalvu kufanele zihlolwe ukuthi ziyavuza yini futhi zibonisa izimpawu zokukhishwa noma ukuqina, okuvumela kokubili ukulahleka koketshezi nokungena kokungcola. Lapho kudingeka ukushintshwa, ukusebenzisa izingxenye zekhwalithi ephezulu ezihambisana nezimfuneko zokuqala zokuhambisana kwempahla, izinga lokucindezela, nobubanzi bezinga lokushisa kubalulekile ekugcineni ubuqotho bohlelo. Isibonelo, ukukhetha izivalo ezenziwe nge-polyurethane noma i-FKM esikhundleni se-NBR evamile kungathuthukisa kakhulu impilo yesevisi ezinhlelweni ezinamazinga okushisa aphezulu noma uketshezi olunamandla. Ngokufanayo, ukukhetha amahose aqiniswe ngocingo anemingcele yokucindezela eyanele kunciphisa ubungozi bokwehluleka okungalindelekile. Ilogi yokuhlola ebhalwe kahle elandelela izikhathi zokushintsha namaphethini okwehluleka inikeza idatha ebalulekile yokuthuthukisa amasu okulungisa nokuhlonza izinkinga eziphindaphindayo emijikelezweni ethile noma ezimweni zokusebenza.

Ukuqapha okuqhubekayo noma ngezikhathi ezithile kwengcindezi kanye nezinga lokushisa lesistimu kubalulekile ekutholeni izinkinga ngaphambi kokuba zidale ukulahlekelwa okukhulu ekusebenzeni kahle. Ingcindezi yokusebenza ephakeme kunokudingekayo imosha amandla ngokwanda kokuvuza kanye nomthwalo owengeziwe, kuyilapho ingcindezi ephansi kakhulu ingakhombisa amaphampu agugile, ama-valve okukhulula anamathele, noma ukudlula kwangaphakathi. Ukufaka ama-digital pressure transducer ezindaweni ezibalulekile zokuhlola kuwo wonke umjikelezo kuvumela abasebenzi ukuthi baqhathanise izinombolo zesikhathi sangempela nezindinganiso eziyisisekelo futhi babone ukwehla kusenesikhathi. Ukuqapha izinga lokushisa kubalulekile ngokufanayo, njengoba ukukhuphuka kuka-10°C ngaphezu kwebanga elifanele kunganciphisa ukuphila kwe-hydraulic fluid ngohhafu futhi kusheshise ukonakala kwe-seal. Ukuqinisekisa ukuthi ama-heat exchanger, ama-cooler, kanye nosayizi we-reservoir anele umthwalo wokushisa wohlelo kusiza ukugcina amazinga okushisa kawoyela ezinzile. Uma kuhlanganiswa nezinqubo ezifanele zokufudumeza ngesikhathi sokuqala okubandayo, le mikhuba yokuqapha ivimbela ukushaqeka okubangelwa ukushisa kanye nokungafani kwe-viscosity okungalimaza izingxenye. Idatha eqoqwe kumarekhodi engcindezi nezinga lokushisa futhi isekela ukumodela okubikezelayo, okunika amandla amaqembu okulungisa ukuhlela ukungenelela ngqo lapho izimo zikhombisa izinkinga ezizayo kunokuthembela ezinhlelweni ezisuselwe ekhalendeni.

Ngisho nezingxenye ze-hydraulic ezigcinwe kahle kakhulu zinesikhathi esilinganiselwe sokusebenza, futhi ukulandela uhlelo lokushintsha olusebenzayo kuyisihluthulelo sokugwema ukuphazamiseka okungahleliwe nokugcina ukusebenza kahle kwesistimu. Amaphampu, ama-motor, ama-valve, nama-cylinder wonke akhombisa izindlela zokuguga ezinciphisa kancane kancane ukusebenza kahle kwe-volumetric ne-mechanical; ukuwashintsha ngezikhathi ezinconyiwe, noma lapho ukuqapha isimo kubonisa ukwehla kokusebenza, kubuyisela isistimu emandleni ayo okuqala. Lapho uhlela ukushintsha, kufanele ucabangele ukuthi imiklamo emisha, esebenza kahle kakhulu ingaletha ukusebenza okungcono noma ukusetshenziswa kwamandla okuphansi. Isibonelo, ukuthuthukisa kusuka kuma-fixed-displacement ukuya kuma-variable-displacement piston pumps kuvumela isistimu ukuthi ifanise ukugeleza nesidingo, kunciphise kakhulu ukulahleka kwe-parasitic ngezikhathi zokungasebenzi noma ngezikhathi zomthwalo ophansi. Ngokufanayo, ukushintsha ama-directional valves amadala ngama-proportional noma ama-servo valves kungathuthukisa ukunemba kokulawula futhi kunciphise ukwehla kwengcindezi. Ukusebenzisa izingxenye zokushintsha ezisezingeni eliphezulu ezivela kubathengisi abathembekile kuqinisekisa ukuthi isistimu ethuthukisiwe ihlangabezana noma yeqe imininingwane yemishini yokuqala. Uhlelo lokushintsha olunamasu, olusekelwa ukuhlaziywa kwezindleko zomjikelezo wempilo, luguqula ukuvuselelwa kwezingxenye kusuka ezindlekweni zokusabela kube utshalomali olukhiqiza inzuzo ekuthembekeni kwe-hydraulic yesikhathi eside.

Ukubunjwa (Viscosity) kuyisici esibaluleke kakhulu emzimbeni wamanzi we-hydraulic, okuthinta ngqo ubukhulu befilimu, ukuvuza kwangaphakathi, ukusebenza kwepompo, kanye nokusabela kwesistimu iyonke. Ukukhetha izinga elifanele lokubunjwa kwezinga lokushisa elisebenzayo lomsebenzi kuqinisekisa ukuthi uketshezi lugcina ifilimu eyanele yokugcoba ngaphansi kwezimo zokushisa okuphezulu ngenkathi lusagobhoza kalula ngesikhathi sokuqala okubandayo. Empeleni, lokhu ngokuvamile kusho ukukhetha uwoyela we-hydraulic onezigaba eziningi noma ukucabangela ukusetshenziswa koketshezi olune-Indexi Yokubunjwa (VI) ephezulu ukuze kuncishiswe ushintsho lokubunjwa kuwo wonke amazinga okushisa. Lapho kusetshenzwa ezindaweni ezinzima, uketshezi lwe-hydraulic olwenziwe lunikeza ukuzinza okuhle kakhulu kokushisa, ukumelana ne-oxidation, kanye nempilo yokusebenza ende uma kuqhathaniswa namafutha avamile amaminerali, nakuba ngezindleko eziphakeme zokuqala. Ukuhlolwa okuvamile kokubunjwa njengengxenye yohlelo lokuhlaziya uketshezi kuqinisekisa ukuthi uwoyela usahlangabezana nezimfuneko futhi awonakaliswanga ukushefa noma ukungcola. Ukugcina ukubunjwa okufanele akukhona nje ukukhathazeka ngokugcoba — kungumshayeli oqondile wokusebenza kahle kwesistimu ye-hydraulic, njengoba nokuphambuka okungu-10% ekubunjweni okuhlosiwe kungathinta ngokulinganayo ukushefa kwepompo nokungaguquguquki kwejubane le-actuator.

Ukukhetha uhlelo olufanele lokuhlunga kuhilela ukuqonda kokubili isilinganiso se-micron kanye ne-beta ratio yezinto zokuhlunga, njengoba lezi zinquma ukuthi uhlelo lususa kahle kangakanani izinhlayiya zosayizi othile. Isihlungi esine-beta_x = 200 sisa u-99.5% wezinhlayiya ezinkulu kuno-x microns, kuyilapho i-beta_x = 1000 isa u-99.9%, okwenza lokhu kokugcina kuthandeke ezinhlelweni ezinengxenye ezinemikhawulo emincane njengama-valve e-servo noma amaphampu e-piston anomfutho ophezulu. Ukubekwa kwezihlungi — ukumunca, umfutho, ukubuya, nangaphandle kwe-inthanethi — kufanele kuklanyelwe ukuvikela izingxenye ezibucayi kakhulu kuyilapho kugcinwa ukwehla komfutho okwamukelekayo ezintweni zokuhlunga. Ukuhambisana kwezinto kudlulela ngale kwezivalo namahose ukuze kufake nezinto zokuhlunga ngokwazo, njengoba okunye uketshezi olwenziwe noma izinhlelo ezisebenza emazingeni okushisa aphezulu zidinga izinto ezikhethekile ze-fiberglass noma i-metal mesh esikhundleni se-cellulose evamile. Ukwengeza, umklamo we-reservoir kufanele uhlanganise ama-baffles, ama-diffuser, nokucwiliswa okufanele komugqa wokubuya ukuze kugwenywe ukungena komoya nokuhlala kwezinhlayiya. Ngokufanisa isu lokuhlunga nokuzwela kwezinhlayiya eziyingozi ezingxenyeni zohlelo, onjiniyela banganciphisa kakhulu amazinga okuguga futhi bandise isikhathi phakathi kokulungiswa okukhulu.

Indawo lapho uhlelo lwe-hydraulic lusebenza khona ibeka izithiyelo okufanele zicatshangelwe kunoma yiluphi uhlelo lokuthuthukisa. Amazinga aphezulu okushisa, umswakama, uthuli, nokudlidliza konke kusheshisa ukuwohloka koketshezi nokugqoka kwezingxenye, okudinga ukuthathwa kwamasampula kaningi kanye nezixazululo eziqinile zokuhlunga nokupholisa. Izinhlelo ezijikeleza njalo noma ezisebenza ngomfutho ophezulu isikhathi eside zikhiqiza ingcindezi eningi yokushisa nemishini, okwenza ukukhethwa kwezinto zokusebenza nokuhambisana kwezivala kube okubaluleke kakhulu. Umklamo ofanele wohlelo futhi uhlanganisa usayizi owanele wethangi — ithangi elincane kakhulu linciphisa isikhathi sokuhlala ukuze umoya uhlukane nokungcola kuhlale phansi, kuyilapho elilinganiswe kahle livumela uketshezi ukuthi luphole futhi lukhiphe umoya ngokwemvelo. Ukusetshenziswa kwama-accumulators kungashelela izingcindezi eziphakeme, kunciphise ukujikeleza kwepompo, futhi kugcine amandla ezidingo eziphakeme, konke okunomthelela ekusebenzeni kahle nokunciphisa umthwalo kumshini oyinhloko. Ngokuhlola lezi zimo zokusebenza nezici zomklamo ngokuphelele, amaqembu okulungisa angathola amathuba okunciphisa izingcindezi nokuthuthukisa ukwethembeka kohlelo lwe-hydraulic ngokuthuthukiswa okuqondisiwe nokulungiswa kwezinqubo.

Uma zonke izindlela zokunakekela kanye nezinto zobuchwepheshe ezichazwe ngenhla zisetshenziswa ngokungaguquki, izinzuzo zidlulela kude nje ngaphezu kokuthuthukiswa kokusebenza okulula. Okokuqala nokubalulekile, uhlelo lwe-hydraulic olulungiselelwe kahle lusebenzisa amandla amancane kakhulu — ngokuvamile kusukela ku-10% kuya ku-30% kuncane kunohlelo olunganakwa — okunciphisa ngqo izikweletu zikagesi kanye nomthelela wekhabhoni womsebenzi. Ukusetshenziswa kwamandla okuphansi nakho kusho ukuthi kukhiqizwa ukushisa okuncane okuyimfucuza, okunciphisa umthwalo ezinhlelweni zokupholisa futhi kuthuthukise ukusebenza kahle jikelele. Ukuncipha kokuvuza kwangaphakathi kanye nokulahlekelwa ukungqubuzana kuhumushela ekusebenzeni okushelelayo, izikhathi zomjikelezo ezihambisanayo, kanye nekhwalithi engcono yomkhiqizo ezinhlelweni zokukhiqiza. Izindleko zokusebenza ziyancipha njengoba ukushintshwa kwezihlungi, ukugcwaliswa kwamafutha, kanye nokulungiswa okungahleliwe kuba yinto engavamile, kuyilapho ukuphila okunwetshiwe kwamaphampu, ama-motor, ama-valve, nama-cylinder kuhlehlisa izindleko zokushintsha impahla. Ukuncishiswa kwesikhathi sokungasebenzi, okungenzeka kube yinzuzo ebonakala kakhulu, kuvikela izinhlelo zokukhiqiza, izithembiso zokulethwa, kanye nemithombo yemali engenayo.
