Ukuhlaziywa nokuxazulula izinkinga zamaphutha esistimu yokugcotshwa kwe-excavator

Lesi sihloko sethula kafushane ukuhlaziya amaphutha athile kanye nezindlela zokuxazulula izinkinga ngokusebenzisa izimo zangempela zokwehluleka okuyingxenye ohlelweni lokugcotshwa okumaphakathi lwabavubukuli ngesikhathi sokusebenza, ngethemba lokuba usizo kubangani nabo abanezinkinga ezinjalo.

Phakathi nokusebenza kwefosholo likagesi, i-alamu yephutha yakhala kungazelelwe, futhi isikrini sokubonisa ikhonsoli esisebenzayo sabonisa: ukucindezela okuphansi epayipini legesi kanye nokwehluleka kokugcotshwa kukawoyela owomile okuphezulu. Iya ekamelweni lokuthambisa ukuze uhlole isistimu kawoyela eyomile ephezulu usebenzisa ukulawula okwenziwa ngesandla. Qala uhlole ukuthi ithangi likawoyela liyashoda yini kugrisi, bese uphendulela inkinobho yokulawula uwoyela owomile ephezulu isuke endaweni ezenzakalelayo iye endaweni esebenza ngesandla, bese uhlola umfutho womthombo womoya ophakela iphampu yomoya. Ukucindezela kuvamile, i-valve ye-solenoid inikwe amandla, futhi iphampu ye-pneumatic iqala ukusebenza (ipompo ijwayelekile) , lapho ingcindezi epayipini ifinyelela inani elibekiwe, i-valve ehlehlayo ihlehla ngokujwayelekile, kodwa iphampu ye-pneumatic iyaqhubeka nokusebenza. Ngemuva kokuhlaziywa, iphutha lokuvuza kukawoyela epayipini elikhulu laqala ukuqedwa, kodwa iphampu ye-pneumatic yaqhubeka nokusebenza ngemva kokuba i-valve ehlehlayo ihlehlisiwe (ukulawulwa kohlelo lukagesi lwe-PLC yilokhu: ngesikhathi sokusebenza okwenziwa ngesandla, i-valve ehlehlayo ihlehla ngemva kokucindezela ipayipi ifinyelela inani elibekiwe , iswishi yayo yokuhamba inika isignali kagesi, i-valve ye-solenoid ivaliwe, futhi iphampu iyeka ukusebenza). Kunganqunywa ukuthi kukhona iphutha endaweni ethile ku-valve ehlehlayo. Okokuqala hlola iswishi yokuvakasha. Uma i-valve yokuhlehla isebenza, iswishi yokuhamba isebenza ngokujwayelekile. Bese uhlola idivayisi yokuthumela isignali yeswishi yokuhamba bese uvula ikhava yebhokisi. Kuvele ukuthi enye yezintambo zangaphandle zedivayisi yokuthumela iwile. Ngemva kokuyixhuma, phinda uhlole, yonke into evamile.

Isizathu somfutho ophansi epayipini legesi senzeka. Ngemva kokuhlaziya ngokucophelela, kwavela ukuthi ngemva kokuba i-valve ehlehlayo ohlelweni lokugcobisa uwoyela owomile olungaphezulu lwehlulekile, i-valve ye-solenoid yayilokhu inika amandla futhi iphampu yomoya yayilokhu isebenza, okwenza umfutho wepayipi omkhulu ube ngaphansi kunenani eliphansi kakhulu elibekwe i-relay yokucindezela. ukuqapha umfutho womoya. Ingcindezi yokuqala yokulayisha yokulayisha ye-compressor yomoya ingu-0.8MPa, kanti ingcindezi evamile ebekwe imitha yokubonisa umfutho womoya wethangi lokugcina komoya futhi ingu-0.8MPa (umugqa oyinhloko wokuqapha umfutho womoya inani eliphansi kakhulu lomfutho womoya ojwayelekile) . Njengoba iphampu ye-pneumatic iqhubeka nokusebenza futhi idla umoya, futhi i-compressor yomoya nayo inenqubo yokukhipha okuzenzakalelayo lapho ilayisha kabusha, idinga futhi ukusebenzisa inani elithile lomoya. Ngale ndlela, umfutho womoya wepayipi elikhulu ungaphansi kuka-0.8MPa, futhi idivayisi yokutholwa komfutho womoya I-alamu yephutha yepayipi eliphansi izokhala.

ukuxazulula inkinga:
Lungisa ingcindezi yokuqala yokulayisha yokulayisha ye-compressor yomoya ibe ngu-0.85MPa, futhi umfutho ojwayelekile obekwe imitha yokubonisa umfutho womoya wethangi lokugcina komoya uhlala ungashintshile, osengu-0.8MPa. Ngesikhathi sokusebenza okwalandela, akuzange kube khona ukwehluleka kwe-alamu kokucindezela komugqa oyinhloko ophansi.

Phakathi nokuhlolwa okuvamile, kwatholakala ukuthi i-valve ehlehlayo ohlelweni lokugcobisa uwoyela owomile olungaphezulu ithatha imizuzwana engaphezu kweshumi ubude kunokuvamile. Ukusabela kokuqala kwaba ukuthi ingabe kukhona ukuvuza kukawoyela epayipini elikhulu. , ihlolwe eduze kwepayipi elikhulu ukusuka ku-valve ehlehlayo ukuya kumsabalalisi ngamunye, futhi yathola ukuthi akukho ukuvuza kukawoyela. Hlola ithangi likawoyela. Amafutha anele. Kungase kube nokuvinjwa kwamapayipi. Hlukanisa ipayipi likawoyela elixhuma iphampu yomoya kanye nevalvu ehlehlayo. Ngemuva kokusebenza ngesandla, ukuphuma kwamafutha kujwayelekile. Inkinga ingase ilele ku-valve ehlehlayo. Okokuqala, qaqa idivayisi yokuhlunga endaweni yokungena kawoyela yevalvu ehlehlayo, khipha isici sokuhlunga, futhi uthole ukuthi kunemfucumfucu eminingi kusici sokuhlunga, futhi yonke ingxenye yesihlungi isicishe ivalwe uhhafu. (Kungase kube ukungcola okuwele ethangini ngenxa yokunganaki komsebenzisi lapho efaka uphethiloli). Ngemuva kokuhlanza, yifake, xhuma ipayipi, qala iphampu ye-pneumatic, futhi isebenza ngokujwayelekile.

Ngesikhathi sokusebenza kwe-excavator, ama-alamu okwehluleka kokugcoba avame ukukhishwa, okungenzeka kungabangelwa izinkinga zamapayipi noma izingxenye zokugcoba ohlelweni lokugcoba. Uma lokhu kwenzeka, qala uhlole ukuthi ithangi likawoyela liyashoda yini kuwoyela, bese uhlola izingxenye zokugcoba (okuhlanganisa i-valve ye-solenoid enikeza umoya empompini yomoya) kanye nokucindezela komthombo womoya wepompo ye-pneumatic ngokulandelana. Uma konke kujwayelekile, udinga ukusebenzisana nabasebenzi bakagesi ukuze nisebenze ndawonye. Hlola izintambo zesistimu kagesi ukuze uthole izingxenye ezihlobene nesistimu yokugcoba. Ngaphezu kokuthola nokubhekana nezinkinga ngesikhathi esifanele ngemva kokutholakala kwephutha ohlelweni lokuthambisa, ukuhlolwa okudingekayo nokugcinwa kokugcinwa kwesistimu yokugcoba kufanele kwenziwe ukuze kutholwe futhi kuqedwe izingozi ezifihliwe kusenesikhathi ukuze kuqinisekiswe ukusebenza okuvamile kwemishini.

Uhlelo lokuthambisa oluphakathi nendawo lusebenzisa ukunikezwa kukawoyela okumaphakathi kusuka kumaphampu kawoyela kanye nokugcotshwa kwephuzu elingaguquki ohlelweni oluvaliwe, olugwema izinkinga ezinjengokungcoliswa kwamafutha kanye namaphoyinti okugcoba angekho okubangwa ukugcwaliswa kwamafutha okwenziwa ngesandla. Ukusebenzisa ukulawulwa kohlelo lwe-PLC, ukunikezwa kukawoyela okuvamile nokulinganisa kugwema izinkinga ezinjengokumosha uwoyela wokugcoba kanye nesikhathi sokugcoba esingalungile esibangelwa ukugcwaliswa kwamafutha okwenziwa ngesandla. Ukuthi amaphutha enzeka ngesikhathi sokusebenza kohlelo lokuthambisa oluphakathi nendawo angasingathwa ngesikhathi azodlala indima ebaluleke kakhulu ekuthuthukiseni ukusebenza kahle kwemishini.

Uma i-excavator yakho idinga ukuthenga okuhlobeneizesekeli excavatorngesikhathi sokulungisa nokulungisa, ungaxhumana nathi. Uma udinga ukuthenga i-excavator entsha noma i-i-excavator eyenziwe ngesandla, ungaphinda usithinte. I-CCMIE ihlinzeka ngezinsiza eziphelele zokuthengisa ama-excavator.
