Iphampu likakhonkoloi-valvelawula ukhonkolo wephampu yeloli ye-hydraulic system lapho uhlangabezana nokwehluleka ukuthi ungabhekana kanjani nakho?
Ukuxuba uhlelo lwesekethe lusetshenziswa kabanzi empompini kakhonkolo njengamanje. Uhlelo luqukethe impompo eyisizayo (iphampu yegiya), ivalvu yokukhulula ebekwe phezulu, i-pressure relay, i-electromagnetic reverse valve kanye ne-two-way hydraulic motor. Ukuxuba umfutho ophakeme kawoyela kulawulwa yi-valve echichimayo yesitaki, i-electromagnetic directional valve electromagnetic DT amandla okusebenza ngokufanele, i-valve ehlehlisayo kwesokunxele, injini ye-hydraulic motor enezindlela ezimbili iyazungezisa, shayela i-hopper ku-blender uye kwi-hopper yesibili yokuxuba kukhonkolo, futhi i-cylinder kakhonkolo yokudla, lapho i-mixer blade iyinhlanganisela enamathele ngaphakathi kwe-hopper, Lapho ingcindezi ohlelweni ikhuphukela kungcindezi emisiwe ye-relay yokucindezela, i-relay yokucindezela iyaphuma.
Ukuxuba isistimu yesekethe yephampu kakhonkolo evame ukusetshenziswa njengamanje, isistimu yakhiwe ngepompo elisizayo (iphampu yegiya), ivalvu yokukhulula indawo ephezulu, i-pressure relay, i-electromagnetic reversing valve kanye ne-two-way hydraulic motor.
Ukuxuba umfutho ophakeme kawoyela kulawulwa yi-valve echichimayo yesitaki, i-electromagnetic directional valve electromagnetic DT amandla okusebenza ngokufanele, i-valve ehlehlisayo kwesokunxele, injini ye-hydraulic motor enezindlela ezimbili iyazungezisa, shayela i-hopper ku-blender uye kwi-hopper yesibili yokuxuba kukhonkolo, futhi i-cylinder kakhonkolo yokudla, lapho i-mixer blade iyinhlanganisela enamathele ngaphakathi kwe-hopper, Lapho ingcindezi ohlelweni ikhuphukela kumfutho omisiwe we-pressure relay, i-pressure relay ithumela isignali ukuze inikeze amandla i-electromagnetic DT, i-valve ehlehlayo isebenza indawo efanele, kanye ne-hydraulic motor ishayela i-agitator ukuthi ijikelezise emuva, ukuze isamba esibambeke ku-agitator iwe.
Lapho i-agitator ihlehla izikhathi ezimbalwa, i-electromagnetic izocisha ngokuzenzakalelayo, i-valve ehlehlayo izophinde iqhubeke kwesokunxele, futhi injini ye-hydraulic izoshayela i-agitator ukuthi iguquke.
Izici Zomsebenzi:
l) Isistimu yesekethe kawoyela eyinhloko inomsebenzi wamandla njalo. Ipompo eyinhloko ihlinzeka ngamafutha okucindezela kumjikelezo kawoyela oyinhloko kanye nomjikelezo wamafutha we-valve yokusabalalisa. Indima yephampu eyisizayo ukulungisa ngokuzenzakalelayo indlela eguquguqukayo yepompo eyinhloko ukuze kuqinisekiswe ukuthi iphampu eyinhloko isesimweni samandla angashintshi. Lapho ingcindezi iyancipha ngokushintsha komthwalo, ukugudluzwa kwepompo eyinhloko kuyanda futhi amandla okukhipha iphampu eyinhloko agcinwa engashintshi, engawasebenzisa ngokugcwele amandla emoto, ithuthukise ukusebenza kahle nokusebenza futhi ivimbele imoto ukuthi ingangeni. ukulayisha ngokweqile.
2) kumasilinda amabili amakhulu we-hydraulic amise i-valve yokuthembela, i-valve inemisebenzi emithathu: lapho i-hydraulic cylinder piston isendleleni, ukuphela kwamafutha phezu kwe-buffer ye-throttle valve yendlela eyodwa ukuze uvule umlomo, wenze ingxenye ephezulu. uwoyela wokucindezela ngowoyela we-buffer endaweni enengcindezi ephansi, wehlise umehluko wengcindezi ye-cavity, isivinini se-piston siyancishiswa, ufeze inhloso ye-buffer, futhi ulungiselele ukuguqulwa kwepiston; Ingasetshenziselwa ukugcwalisa umgodi wamafutha ukuze kuqinisekiswe ukushaywa okuphumelelayo kwepiston. Amafutha esignali ngokulawula imbobo kawoyela ukwenza i-valve yokushintsha i-hydraulic ukuze iqedele isenzo sokumpompa esilandelayo sepompo likakhonkolo.
3) Xhuma umjikelezo kawoyela we-valve yokusabalalisa ohlelweni oluyinhloko lwesifunda samafutha. Njengamanje, uhlelo lwasekhaya lwe-hydraulic lwephampu kakhonkolo luvamise ukuhlonyiswa ngohlelo lwesekethe kawoyela olungcono kakhulu lwevalvu yokusabalalisa. Ukuze uqinisekise ukuguqulwa okunamandla nokusheshayo kwe-valve yokusabalalisa, i-accumulator kufanele isethwe ohlelweni.
Ekwakhiweni kwesistimu ye-hydraulic, ngokusebenzisa i-hydraulic reversing valve kanye ne-electromagnetic reversing valve izosabalalisa uwoyela we-valve kanye nesistimu kawoyela eyinhloko. I-hydraulic reversing valve kanye ne-electromagnetic reverse valve valves ayinhlanganisela. Alawulwa uwoyela ocindezelayo osuka ku-autonomous hydraulic cylinder, ukuze uwoyela ocindezelayo ophuma empompini omkhulu ungene ngokushintshana kumasilinda amabili okusabalalisa ama-valve, ebona ukuhlehliswa kwe-valve yokusabalalisa, futhi ahlangabezane nezidingo zephampu kakhonkolo ngokushesha. kanye nokuhlehla okunamandla kwe-valve yokusabalalisa.
Indlela yokubhekana nokuhluleka kwesistimu ye-hydraulic yeloli yepompo likakhonkolo? Amaphutha ajwayelekile kanye nezindlela zokwelapha ze-hydraulic system yeloli yepompo likakhonkolo:

Isixazululo: Lungisa ukucindezela kwe-valve yokusiza enanini elishiwo, futhi uthuthukise isifunda uma kunesidingo.
Inkinga: Ukulahlekelwa amandla amaningi ngenxa yokuvuza nokungqubuzana komshini ohlelweni.
Isixazululo: Hlola ukuvuza, uthuthukise uphawu, uthuthukise ukunemba kwemishini yezingxenye ezihambayo, ukunemba komhlangano kanye nezimo zokugcoba.
5, ukudlidliza
Izinkinga: iphampu ye-hydraulic, i-air inhalation, indawo yokufaka iphezulu kakhulu, ukumelana nokumuncwa kukawoyela, ukunemba kwezinyo legiya akwanele, i-blade ibambekile futhi iphukile, i-plunger ibambekile futhi iselula ayiguquki, ukugqokwa kwezingxenye kwenza imvume ibe nkulu kakhulu.
Isixazululo: Faka esikhundleni sophawu lwendawo yokufaka uwoyela, idigri esuka embobeni yokudonsa uwoyela iye embotsheni yokudonsa uwoyela wephampu kufanele ibe ngaphansi kuka-500mm, uqinisekise ububanzi bepayipi lokudonsa, ukulungisa noma ukushintsha izingxenye ezilimele.
Izinkinga: Amafutha we-hydraulic, izinga le-liquid liphansi kakhulu, ukujula kokufakwa kwepayipi lokudonsa akwanele, i-viscosity yamafutha inkulu kakhulu, isihlungi sivinjiwe.
Isixazululo: Engeza uwoyela, welule ipayipi lokumunca bese ucwilisa ekujuleni okucacisiwe, buyisela uwoyela we-viscosity hydraulic, bese uhlanza isisefo.
Izinkinga: i-valve echichimayo, imbobo yokumanzisa evinjiwe, imvume eningi phakathi komgogodla we-valve nesihlalo se-valve, ukwehluleka kwentwasahlobo.
Isixazululo: Hlanza imbobo yokumanzisa, lungisa igebe phakathi kukamongo wevalvu nesihlalo, bese ubuyisela isiphethu.
Inkinga: Enye i-spool ayinyakazi kalula.
Isixazululo: Geza bese ususa.
Izinkinga: Amapayipi, amapayipi azacile, akukho divayisi engashintshi, ukushayisana, ipayipi lokudonsa kanye nepayipi lokubuya kusondele kakhulu.
Isixazululo: Umshini ongashintshi usethelwe ukwandisa ibanga phakathi kwamapayipi nebanga phakathi kwepayipi elimunca nepayipi elibuyayo.
