Kwixesha lotshintsho olukrelekrele loomatshini bokwakha, isiphatho sevalvu yokulawula umqhubi wombane we-excavator siye saba yinto ephambili kwishishini ngokubeka kwayo ngokuchanekileyo ukusebenza, ukuguquguquka kwendawo ebanzi kunye neempawu zobugcisa ezibalaseleyo. Eli candelo litsha elidibanisa ulawulo lwe-elektroniki kunye nokusebenza koomatshini libonelela ngezisombululo ezisebenzayo kwimisebenzi yobunjineli phantsi kweemeko ezahlukeneyo zokusebenza ngokuphucula ukusebenza kwayo yonke indawo.
Umbane ozinzileyo ukuqinisekisa ukusebenza okuthembekileyo kwezixhobo
Ngokuphathelele umbane, esi siphatho sevalvu yokulawula sinokuzivumelanisa nezimo ngendlela egqwesileyo. Uluhlu lwamandla ayo ombane yi-10-32VDC, kwaye ingasebenza ngokuzinzileyo kwiindawo ezahlukeneyo zombane, nokuba kwiimeko zokusebenza ezingazinzanga zombane wexeshana kwintsimi okanye kwiimeko eziqhelekileyo ezinobume obuqhelekileyo bombane, inokuqinisekisa ukusebenza okuqhelekileyo kwesixhobo. Kwangaxeshanye, iimpawu zayo zokusetyenziswa kwamandla aphantsi zibalasele kakhulu, yi-100mA okanye ngaphantsi, nto leyo enciphisa kakhulu ukusetyenziswa kwamandla kwesixhobo kwaye iphucula ukusebenza kakuhle kwamandla. Umbane we-pulse unqunyelwe kwi-10A okanye ngaphantsi, nto leyo ethintela ngokufanelekileyo umonakalo kwisixhobo obangelwa kukukhwankqiswa kwamandla okugqithisileyo kwaye iqinisekisa ukhuseleko kunye nokuzinza kwenkqubo yombane yonke.
Ukudluliselwa kwesignali ngokufanelekileyo kulawulo oluchanekileyo
Inxalenye yesiphumo sesignali yeyona nto ibalulekileyo kule mveliso. Xa kusetyenziswa iprotocol yonxibelelwano ye-CAN (SAE J1939) EJM1, idilesi yomthombo imiselwe kwi-249, izinga lonxibelelwano lifikelela kwi-250kbps, kwaye ngexesha lesampulu ye-10ms, imiyalelo yokusebenza ingadluliselwa ngokukhawuleza nangokuchanekileyo kwinkqubo yolawulo lwe-excavator. Oku kuvumela ukuba yonke into eyenziwa ngumsebenzisi ibuyiselwe kwisixhobo ngexesha elifanelekileyo nangendlela echanekileyo, kufezekisa ukuchaneka kokusebenza kwinqanaba le-millimeter. Ukuchaneka kwesiphumo nako kugqwesile phantsi kweemeko ezahlukeneyo zobushushu. Kwimeko-bume ye--10 – +50°C, ukuchaneka okuphakathi kunokufikelela kwi-±2%, kwaye kwimeko-bume ye--40 – +75°C, inokugcinwa malunga ne-±3%, ukuqinisekisa ukuba izixhobo zinokwenza imisebenzi ngokuzinzileyo nangokuchanekileyo kwiindawo ezahlukeneyo ezinzima.
Iiparameters zoomatshini ezichanekileyo, zombini ukuqina kunye nentuthuzelo
Ngokwembono yeeparamitha zokusebenza koomatshini, isiphatho sevalvu yokulawula sisebenza kakuhle. I-hysteresis yaso ilawulwa kwi-±1.6% okanye ngaphantsi, kwaye ukuphambuka okuphakathi koomatshini yi-0.5° okanye ngaphantsi, okwenza ukusebenza kwesiphatho kubonakale kuthambile kwaye kuphendula, kunciphisa ngempumelelo iimpazamo zokusebenza kwaye kuphucule intuthuzelo kunye nokuchaneka kokusebenza. Uluhlu lobushushu benkonzo yi--40-75°C, enokuziqhelanisa neendawo ezahlukeneyo ezigqithisileyo ukusuka kwiindawo ezibandayo ze-polar ukuya kwiintlango ezishushu, yandisa kakhulu iimeko zokusetyenziswa kwezixhobo. I-torque ephezulu yokusebenza yi-226N/m, eqinisekisa ukuba isiphatho sihlala ixesha elide ngokwaneleyo ukumelana nokusetyenziswa ngamandla aphezulu ngelixa kuqinisekiswa amandla afanelekileyo okusebenza.
Imiyalelo yokutshintsha ekrelekrele, amava okusebenza alungiselelwe kakuhle
Ngokwemiyalelo yokutshintsha, imveliso nayo yenzelwe ngononophelo. I-voltage kunye nombane olinganisiweyo zahlulwe zibe ziinkcukacha ezimbini: i-DC30V/3A (umthwalo wokumelana) kunye ne-DC30V/1A (umthwalo wokumelana). Umthamo omncinci wokuboleka yi-DC5V/160mA kunye ne-DC30V/26mA. Umthamo wokusebenza kunye namandla okusebenza nawo amiselwe ngokufanelekileyo ngokweeswitshi ezahlukeneyo, ezifana neeswitshi 1 kunye ne-3 ziyi-1mm/4N, kwaye iswitshi 2 yi-1mm/6N. Ezi parameters zenza ukuba ukusebenza kweswitshi kube buthathaka kwaye konge abasebenzi, nto leyo ephucula ngakumbi amava omqhubi. Kwangaxeshanye, ubushushu bayo benkonzo bukwayi-40 - 75°C, ukuqinisekisa uzinzo kunye nokuthembeka komsebenzi weswitshi kwiindawo ezahlukeneyo.
Esi siphatho sevalvu yokulawula umqhubi wombane we-excavator sisebenza kakuhle kakhulu kwiiparameter kumbane, ukuhanjiswa kwesignali, ukusebenza koomatshini kunye nemiyalelo yokutshintsha, ngokungathandabuzekiyo inika isiqinisekiso esiqinileyo sokusebenza ngobuchule nangokuchanekileyo kwe-excavator. Ngokukhuthazwa kwayo kancinci kancinci kunye nokusetyenziswa kwayo kwimarike, ngokuqinisekileyo iya kukhuthaza ishishini loomatshini bokwakha kwinqanaba eliphezulu kwaye izise ukusebenza kakuhle kunye nokuphuculwa komgangatho kwiiprojekthi ezahlukeneyo zokwakha zobunjineli.
