Udinga namanye ama-valve ukuze uphephe futhi usebenze kahle. Ama-valve okuhlola avimba uketshezi ukuthi lungahambi ngendlela engafanele. Amavalvu esibili okusiza agcina i-actuator iphephile ekucindezelweni kakhulu. Ama-valve e-anti-cavitation asiza ngezinkinga eziphansi zokucindezela. Ama-valve okudambisa enza izinguquko zengcindezi zithambe. Ama-valve okwehlisa ingcindezi asiza izilawuli zomshayeli ukuthi zisebenze kangcono.
Amavalvu angu-4/3 akuvumela ukuthi ulawule amasilinda asebenza kabili ngezindlela ezintathu: ukuphuma, ukungena, nokuma. Ama-valve angu-4/2 ashintsha ukugeleza ngezindlela ezimbili. Ukhetha i-valve ngohlobo lwesilinda kanye nendlela ofuna ukuyilawula ngayo i-tipping.
Amapayipi kanye ne-Reservoir
Kufanele ukhethe amapayipi kanye nedamu elilingana nesistimu yakho ye-hydraulic. Amapayipi ahambisa uketshezi olusebenzisa amanzi phakathi kwezingxenye. Ukhetha impahla ye-hose ngokusekelwe kulokho okudingayo. Insimbi, insimbi engagqwali, i-aluminium, nepulasitiki yizinto ezijwayelekile zamapayipi. Ngamunye unamaphuzu amahle namabi.
I-reservoir ibamba uketshezi lwe-hydraulic. Kufanele ibe nkulu ngokwanele ukugcwalisa amasilinda futhi igcine inani elengeziwe elingu-20%. Ungakwazi futhi nosayizi we-reservoir ukuze ubambe isilinganiso sokugeleza esiphindwe kabili samamotho. Beka i-reservoir eduze ne-pump inlet. Lokhu kumisa i-cavitation futhi kugcina iphampu iphephile. Sebenzisa amapayipi amakhulu, aqondile endaweni yokungena kumasistimu we-hydraulic wamaloli.
I-reservoir idinga i-vent noma i-cap yokuphefumula. Lokhu kuvimbela iphampu ukuthi yome futhi ilimale. Kufanele ubeke amachweba endaweni efanele ukuze kuphole kahle futhi kubuye uwoyela.
Uma ukhetha izingxenye ze-hydraulic, ubheka amandla, ubude be-stroke, isivinini, ingcindezi, isitayela sokukhuphuka, isimo sezulu, ukuthi uyisebenzisa kaningi kangakanani, nokuthi kufanele ihlale isikhathi eside kangakanani.

Ithiphu: Njalo hlola ipayipi kanye nosayizi wereservoir ngaphambi kokuqala umsebenzi wakho we-hydraulic. Ukukhetha izingxenye ezifanele kugcina isistimu yakho ye-hydraulic iphephile futhi isebenza kahle.
Ukuphepha Nokusebenza Kwesistimu
Ukuhlola Imikhawulo Yengcindezi
Kufanele ngaso sonke isikhathi uhlole imikhawulo yokucindezela yesilinda sakho se-hydraulic tipping. Lokhu kugcina okokusebenza kwakho kuphephile futhi kusebenza kahle. Okokuqala, fanisa isilinganiso sokucindezela kwe-valve kusistimu yakho. Imisebenzi eminingi isebenzisa ama-valve alinganiselwe ngamabha angama-300-350. Imisebenzi enzima idinga amavalvu alinganiselwe ngamabha angama-400 noma ngaphezulu. Engeza njalo imajini yokuphepha ngaphezu kokucindezela kwakho okuphezulu kwesistimu. Ukunyakaza okusheshayo kungabangela ukukhuphuka kwengcindezi kanye nemithwalo yokushaqeka. Lawa ma-spikes angalimaza isilinda sakho se-hydraulic uma ungazihleleli.

Qondanisa isilinganiso se-valve nesistimu yakho. Engeza imajini yokuphepha ngaphezu kokucindezela okukhulu. |
Cabanga nge-Pressure Spikes |
Hlela ama-spikes kanye nemithwalo yokushaqeka ukuze ugcine isilinda sakho se-hydraulic siphephile. |
Ukuhlola i-Hydrostatic kukusiza ukuthi uhlole amamajini okuphepha. Hlola isilinda sakho se-hydraulic ngaphansi kwezimo zangempela zokushisa nezimo zomjikelezo. Lokhu kuqinisekisa ukuthi amasistimu wakho we-hydraulic angakwazi ukuphatha umsebenzi wangempela.
Ukuvikelwa kokulayisha ngokweqile
Udinga ukuvikeleka kokugcwala kakhulu ukuze ugcine isilinda sakho se-hydraulic tipping siphephile. Ukulayisha ngokweqile kungabangela ukuvuza, izimpawu eziphukile, noma ukwehluleka kwesilinda. Sebenzisa ama-valve okusiza ukumisa ingcindezi ekukhuphukeni kakhulu. Lawa mavalvu avuleka uma umfutho ukhuphuka kakhulu futhi avikele okokusebenza kwakho. Hlola ukuvuza kwamapayipi, okokufakwayo, namasilinda. Buka ileveli ye-hydraulic fluid bese ubheka uketshezi olumnyama noma olungcolile. Buyisela uketshezi uma kudingeka. Ngaso sonke isikhathi landela uhlelo lokulungisa oluvela kumkhiqizi.
Hlola ukuvuza kwamapayipi, okokufakwayo, namasilinda.
Buka izinga loketshezi kanye nesimo. Faka esikhundleni uma kumnyama noma kungcolile.
Landela ishejuli yokunakekelwa kwazo zonke izingxenye ezisebenza ngogesi.
Ukuhlola Ukusebenza kahle
Ufuna isilinda sakho se-hydraulic tipping sisebenze kahle. Hlola izinga lokugeleza futhi uqiniseke ukuthi lifana nezidingo zesilinda sakho. Khetha ivalvu enamandla okugeleza ngo-20-30% ngaphezu kokugeleza kwakho okuphezulu. Lokhu kusiza ukuvimbela ukwehla kwengcindezi futhi kugcina isilinda sakho se-hydraulic sihamba kahle. Buka ukuhamba kancane noma ukushisa ngokweqile. Lezi zimpawu zisho ukuthi isistimu yakho ye-hydraulic ingase idinge isevisi. Ukunakekelwa okuhle nokuhlola okuvamile kusiza isilinda sakho esisebenza nge-hydraulic ukuthi sihlale siphephile futhi sisebenza kahle.
Ithiphu: Ukuhlola okuvamile nokugcinwa kahle kugcina isilinda sakho se-hydraulic tipping siphephile futhi sisebenza kahle. Ungalokothi weqe lezi zinyathelo uma ufuna ukusebenza kahle kakhulu.
Ungathola ukuthi yini isistimu yesilinda sakho sokusikisela ngokulandela isinyathelo ngasinye. Okokuqala, thola isisindo somthwalo, i-engeli yokufika, nesivinini osifunayo. Okulandelayo, hlola amandla, ukucindezela, nosayizi wesilinda. Futhi, bheka izinga lokugeleza bese ukhetha izingxenye ezifanele. Hlala ubuka imikhawulo yengcindezi futhi wengeze imajini yokuphepha. Abantu abaningi bathola izibalo ezingalungile. Bheka ithebula elingezansi ukuze uthole amaphutha abantu abavame ukuwenza:
Iphutha Elivamile |

I-asymmetry ekunwebeni nasekuhoxiseni amandla |
Indawo yokuhlehla iyindawo ebhorekile kukhishwe indawo yenduku, ngakho amandla awalingani uma kusebenza. |
Ukuziba izici zokuphepha zokubopha induku |
Uma ungahloli ukubosheka kwezinduku, induku ingase igobe noma iphuke ohlelweni lwakho lwe-hydraulic. |
Ugcina isistimu yakho ye-hydraulic iphephile ngokusebenzisa ingcindezi efanele futhi uhlole yonke into. Kumaphrojekthi aqinile, cela uchwepheshe noma usebenzise amathuluzi akhethekile.
FAQ
Iyiphi into ebaluleke kakhulu lapho ulinganisa isilinda esithiphu?
Kufanele uhlole isisindo somthwalo kuqala. Le nombolo ithinta zonke ezinye izibalo. Uma uthwala kanzima, isilinda sakho singase singasebenzi ngokuphepha.
Ungalukhetha kanjani uketshezi olusebenza ngogesi olufanele?
Kufanele ukhethe uketshezi olune-viscosity efanele yesistimu yakho. Hlola imanuwali yakho ngezinhlobo ezinconyiwe. I-viscosity ephezulu ibambezela ukunyakaza. I-viscosity ephansi ingabangela ukushisa ngokweqile.
Kungani amandla okuhoxisa isilinda ehluka kumandla anwetshiwe?
Induku ithatha isikhala ngaphakathi kwesilinda. Lokhu kunciphisa indawo lapho uketshezi luphusha khona ngesikhathi sokuhlehla. Uthola amandla amancane uma uhoxisa.
Kufanele uhlole kangaki ukuphepha kwesistimu ye-hydraulic?
Udinga ukuhlola uhlelo lwakho ngaphambi kwawo wonke umsebenzi. Bheka ukuvuza, amapayipi agugile, noketshezi olungcolile. Ukuhlola okuvamile kugcina okokusebenza kwakho kuphephile futhi kusebenza kahle.
Ungakwazi yini ukusebenzisa ithangi elikhudlwana ukupholisa kangcono?
Ungasebenzisa ithangi elikhulu ukusiza ngokupholisa. Qiniseka ukuthi ithangi lihambisana nezidingo zesistimu yakho. Okukhulu kakhulu kumosha indawo nemali.
