Eli nqaku ngokufutshane lazisa uhlalutyo lweempazamo ezithile kunye neendlela zokusombulula ingxaki ngokweemeko zokwenyani zokungaphumeleli kwinxalenye yenkqubo yokuthambisa esembindini yabembi ngexesha lokusebenza, ngethemba lokuba luncedo kubahlobo nabo baneengxaki ezinjalo.
Impazamo 1:
Ngethuba lokusebenza kwefosholo yombane, i-alarm yephutha ngokukhawuleza yakhala, kwaye isikrini sokubonisa i-console yokusebenza sibonise: uxinzelelo oluphantsi kumbhobho wegesi kunye nokungaphumeleli kwe-lubrication yeoli ephezulu. Yiya kwigumbi lokuthambisa ukuze ujonge inkqubo yeoli eyomileyo ephezulu usebenzisa ulawulo lwezandla. Kuqala jonga ukuba itanki yeoyile imfutshane na igrisi, emva koko ujike iqhosha lokulawula i-oyile eyomileyo ukusuka kwindawo ezenzekelayo ukuya kwindawo yesandla, uze ujonge uxinzelelo lomthombo womoya obonelela ngempompo yomoya. Uxinzelelo luqhelekileyo, i-valve ye-solenoid inamandla, kwaye ipompo ye-pneumatic iqala ukusebenza (ipompo iyinto eqhelekileyo), xa uxinzelelo kwipayipi lufikelela kwixabiso elimiselweyo, i-valve yokubuyisela ibuyele ngokuqhelekileyo, kodwa ipompo ye-pneumatic iyaqhubeka isebenza. Emva kohlalutyo, impazamo yokuvuza kweoyile kumbhobho oyintloko yapheliswa kuqala, kodwa impompo yepneumatic iqhubekile nokusebenza emva kokuba ivalve yokubuyisela umva (ulawulo lwenkqubo yombane yePLC yile: ngexesha lokusebenza ngesandla, ivalve ebuyela umva ibuyela umva emva koxinzelelo kwi-valve. umbhobho ufikelela kwixabiso elimiselweyo , ukutshintshela kwayo ukuhamba kunika uphawu lombane, i-valve ye-solenoid ivaliwe, kwaye ipompo iyeka ukusebenza). Inokumiselwa ukuba kukho impazamo kwindawo ethile kwivalve yokubuyisela umva. Qala ujonge iswitshi yokuhamba. Xa ivalve yokubuyisela umva isebenza, iswitshi yokuhamba isebenza ngokuqhelekileyo. Emva koko jonga isixhobo sokuthumela umqondiso weswitshi yokuhamba kwaye uvule isigqubuthelo sebhokisi. Kuvela ukuba enye yeentambo zangaphandle zesixhobo sokuthumela ziwile. Emva kokuyidibanisa, phinda uphinde, yonke into eqhelekileyo.
Isizathu soxinzelelo oluphantsi kwipayipi yegesi yenzeke. Emva kohlahlelo olucokisekileyo, kwafumaniseka ukuba emva kokuba ivalve ebuyisela umva kwinkqubo yokuthambisa yeoli ephezulu eyomileyo ingaphumelelanga, ivalve yesolenoid yahlala inika amandla kwaye impompo yepneumatic yahlala isebenza, nto leyo ebangela ukuba uxinzelelo lwemibhobho oluphambili lube sezantsi kunelona xabiso liphantsi libekwe luxinzelelo loxinzelelo. ukujongwa koxinzelelo lomoya. Ubuncinci bokulayishwa koxinzelelo lokuqalisa lwe-compressor yomoya yi-0.8MPa, kwaye uxinzelelo oluqhelekileyo olusetiweyo kwimitha yokubonisa uxinzelelo lomoya lwetanki yokugcina umoya lukwayi-0.8MPa (umgca ophambili wokujongwa koxinzelelo lomoya lelona xabiso liphantsi loxinzelelo lomoya oluqhelekileyo) . Ekubeni ipompo ye-pneumatic iqhubeka nokusebenza kwaye idla umoya, kwaye i-compressor yomoya nayo inenkqubo yokukhupha ngokuzenzekelayo xa iphinda ilayishwa, ifuna kwakhona ukuchitha umlinganiselo othile womoya. Ngale ndlela, uxinzelelo lomoya lombhobho oyintloko lungaphantsi kwe-0.8MPa, kunye nesixhobo sokubona uxinzelelo lomoya I-alarm ephantsi yoxinzelelo lwe-alarm iya kuvakala.
ukulungisa ingxaki:
Lungisa ubuncinci bokuqala ukulayishwa koxinzelelo lwe-compressor yomoya kwi-0.85MPa, kunye noxinzelelo oluqhelekileyo olubekwe kwimitha yokubonisa uxinzelelo lomoya kwitanki yokugcina umoya ihlala ingatshintshi, eseyi-0.8MPa. Ngexesha lomsebenzi olandelayo, akukho nto ingaphumeleliyo ye-alarm yoxinzelelo oluphantsi olusezantsi.
Impazamo 2:
Ngethuba lokuhlolwa kwesiqhelo, kwafunyaniswa ukuba i-valve yokubuyisela kwi-oyile eyomileyo ye-lubrication system ithatha ngaphezu kwemizuzwana elishumi kunexesha eliqhelekileyo. Intsabelo yokuqala yaba kukuvuza kweoyile kumbhobho oyintloko. , ihlolwe ecaleni kombhobho oyintloko ukusuka kwivalve ebuyela umva ukuya kumsasazi ngamnye, yaze yafumanisa ukuba akukho kuvuza kweoyile. Jonga itanki yeoli. Igrisi yanele. Kusenokubakho ukuvaleka kwemibhobho. Hlukanisa umbhobho we-oyile odibanisa impompo ye-pneumatic kunye nevalve yokubuya umva. Emva kokusebenza ngesandla, ukuphuma kweoli kuqhelekileyo. Ingxaki isenokuthi ikwivalve ebuyela umva. Okokuqala, qhaqha isixhobo sokucoca kwindawo yokungena yeoli yevalve ebuyela umva, khupha into yokucoca, kwaye ufumanise ukuba kukho inkunkuma eninzi kwindawo yokucoca, kwaye yonke into yokucoca iphantse yavaleka. (Kungaba ukungcola okuwele kwitanki ngenxa yokungakhathali komsebenzisi xa ufaka i-refueling). Emva kokucoca, yifake, udibanise umbhobho, qalisa ipompo ye-pneumatic, kwaye isebenza ngokuqhelekileyo.
Ngethuba lokusebenza kwe-excavator, ii-alamu zokungaphumeleli kwe-lubrication zihlala zikhutshwa, ezinokuthi zingabangelwa yingxaki yemibhobho okanye i-lubrication components kwi-lubrication system. Xa oku kusenzeka, jonga kuqala ukuba itanki yeoli iphelelwe yioyile, kwaye emva koko ujonge amacandelo okuthambisa (kubandakanywa nevalve ye-solenoid enika umoya kwimpompo ye-pneumatic) kunye noxinzelelo lomthombo womoya wempompo yomoya ngokulandelelana. Ukuba yonke into iyinto eqhelekileyo, kufuneka usebenzisane nabasebenzi bombane ukuze usebenze kunye. Jonga i-wiring yesixokelelwano sombane kwizinto ezinxulumene nenkqubo yokuthambisa. Ukongeza ekufumaneni kunye nokujongana neengxaki ngexesha elifanelekileyo emva kokuba impazamo ifunyenwe kwinkqubo yokuthambisa, ukuhlolwa okuyimfuneko kunye nokugcinwa kwenkqubo yokuthambisa kufuneka kwenziwe ukuze kubonwe kwaye kupheliswe iingozi ezifihliweyo kwangethuba ukuze kuqinisekiswe ukusebenza okuqhelekileyo kwesixhobo.
Inkqubo ye-lubrication ephakathi isebenzisa unikezelo lwe-oyile oluphakathi ukusuka kwiimpompo ze-oyile kunye ne-fixed-point lubrication kwinkqubo evaliweyo, ethintela iingxaki ezifana nokungcoliswa kwe-lubricant kunye neendawo ezilahlekileyo zokuthambisa ezibangelwa ukuzaliswa kweoli ye-manual. Ukusebenzisa ulawulo lwenkqubo ye-PLC, ukunikezelwa kweoli rhoqo kunye nobuninzi kuthintela iingxaki ezifana nokuchithwa kweoli yokuthambisa kunye nexesha elingafanelekanga lokuthambisa elibangelwa ukuzaliswa kweoli yezandla. Ingaba iimpazamo ezenzeka ngexesha lokusebenza kwenkqubo ye-lubrication ephakathi ingaphathwa ngexesha iya kudlala indima ebaluleke kakhulu ekuphuculeni ukusebenza kakuhle kwezixhobo.
Ukuba excavator yakho kufuneka ukuthenga ezinxulumeneizixhobo excavatorngexesha lokugcinwa kunye nokulungiswa, ungaqhagamshelana nathi. Ukuba ufuna ukuthenga i-excavator entsha okanye ii-excavator yesandla sesibini, unokuqhagamshelana nathi. I-CCMIE ibonelela ngeenkonzo zentengiso ye-excavator ebanzi.
