Egagasini lokuguqulwa okuhlakaniphile kwemishini yokwakha, isibambo se-valve yokulawula umshayeli kagesi we-excavator sesibe yindawo ebalulekile embonini ngokubeka kwayo ukusebenza okunembile, ukuzivumelanisa nezimo kwendawo ebanzi kanye nezici zobuchwepheshe ezivelele. Le ngxenye entsha ehlanganisa ukulawulwa kwe-elekthronikhi kanye nokusebenza kwemishini inikeza izixazululo ezisebenzayo zokusebenza kobunjiniyela ngaphansi kwezimo zokusebenza ezahlukene ngokusebenzisa ukulungiswa kokusebenza okuphelele.
Ukunikezwa kukagesi okuzinzile ukuqinisekisa ukusebenza okuthembekile kwemishini
Ngokuphathelene nokunikezwa kwamandla, lesi siphathi se-valve yokulawula sinokuvumelana nezimo okuhle kakhulu. Ububanzi baso bamandla kagesi buyi-10-32VDC, futhi singasebenza ngokuzinzile ezindaweni ezahlukahlukene zokunikezwa kwamandla, kungakhathaliseki ukuthi kusezimweni zokusebenza ezingazinzile zokunikezwa kwamandla kwesikhashana ensimini noma ezimweni ezivamile ngokulungiswa kokunikezwa kwamandla okujwayelekile, singaqinisekisa ukusebenza okuvamile kwemishini. Ngesikhathi esifanayo, izici zayo zokusetshenziswa kwamandla aphansi zivelele kakhulu, ziyi-100mA noma ngaphansi kuphela, okunciphisa kakhulu ukusetshenziswa kwamandla kwemishini futhi kuthuthukise ukusebenza kahle kokusetshenziswa kwamandla. Umshini wokushaya ukhawulelwe ku-10A noma ngaphansi, okugwema ngempumelelo ukulimala kwemishini okubangelwa ukushaqeka kwamandla amaningi futhi kuqinisekise ukuphepha nokuzinza kohlelo lonke lukagesi.
Ukudluliswa kwesignali okusebenzayo kokulawula okunembile
Ingxenye yokukhipha isignali iyinto evelele kulo mkhiqizo. Uma sisebenzisa iphrothokholi yokuxhumana ye-CAN (SAE J1939) EJM1, ikheli lomthombo libekwe ku-249, izinga lokuxhumana lifinyelela ku-250kbps, futhi ngesikhathi sokuthatha isampula esingu-10ms, imiyalelo yokusebenza ingadluliselwa ngokushesha nangokunembile ohlelweni lokulawula i-excavator. Lokhu kuvumela ukuthi isenzo ngasinye somqhubi sibuyiselwe emishinini ngendlela efanele nangesikhathi, kufezwe ukunemba kokusebenza kwezinga le-millimeter. Ukunemba kokukhipha nakho kuhle kakhulu ngaphansi kwezimo zokushisa ezahlukene. Endaweni engu--10 – +50°C, ukunemba okuphakathi kungafinyelela ku-±2%, futhi endaweni engu--40 – +75°C, kungagcinwa cishe ku-±3%, kuqinisekiswe ukuthi imishini ingenza imisebenzi ngokuqina nangokunembile ezindaweni ezahlukahlukene eziyinkimbinkimbi.
Amapharamitha omshini oqondile, kokubili ukuqina kanye nenduduzo
Ngokombono wamapharamitha okusebenza kwemishini, isibambo se-valve yokulawula naso sisebenza kahle. I-hysteresis yaso ilawulwa ku-±1.6% noma ngaphansi, kanti ukuphambuka okuphakathi kwemishini kungu-0.5° noma ngaphansi, okwenza ukusebenza kwesibambo kuzwakale kubushelelezi futhi kuphendula, kunciphisa ngempumelelo amaphutha okusebenza futhi kuthuthukise induduzo nokunemba kokusebenza. Ububanzi bokushisa kwesevisi bungu--40-75°C, obungazivumelanisa nezimo ezahlukahlukene ezimbi kakhulu kusukela ezifundeni ezibandayo ze-polar kuya ezihlane ezishisayo, okwandisa kakhulu izimo zokusetshenziswa kwemishini. I-torque ephezulu yokusebenza ingu-226N/m, okuqinisekisa ukuthi isibambo siqinile ngokwanele ukumelana nokusetshenziswa okunamandla aphezulu ngenkathi kuqinisekiswa amandla okusebenza afanele.
Imiyalelo yokushintsha ehlakaniphile, ulwazi olusebenzayo olulungiselelwe
Ngokwemiyalelo yokushintsha, umkhiqizo nawo uklanywe ngokucophelela. I-voltage kanye nogesi olinganiselwe kuhlukaniswe ngezincazelo ezimbili: i-DC30V/3A (umthwalo wokumelana) kanye ne-DC30V/1A (umthwalo wokumelana). Umthamo omncane wokuboleka yi-DC5V/160mA kanye ne-DC30V/26mA. Umthamo wokusebenza kanye namandla okusebenza nawo abekwe ngokufanele ngokwezishintshi ezahlukene, njengezishintshi 1 no-3 eziyi-1mm/4N, kanti iswishi 2 iyi-1mm/6N. Lezi zinhlaka zenza ukusebenza kweswishi kube bucayi futhi konge abasebenzi, okuthuthukisa ulwazi lomqhubi. Ngesikhathi esifanayo, izinga lokushisa lesevisi yayo nalo lingu-40 - 75°C, okuqinisekisa ukuzinza nokuthembeka komsebenzi weswishi ezindaweni ezahlukahlukene.
Lesi siphathi se-valve yokulawula umshayeli kagesi we-excavator sisebenza kahle kakhulu ekuhlinzekeni kwamandla, ekudlulisweni kwesignali, ekusebenzeni komshini kanye nemiyalelo yokushintsha, okungangabazeki ukuthi sinikeza isiqinisekiso esiqinile sokusebenza okuhlakaniphile nokunembile kwe-excavator. Ngokukhushulwa kwayo kancane kancane kanye nokusetshenziswa kwayo emakethe, ngokuqinisekile izothuthukisa imboni yemishini yokwakha ibe sezingeni eliphezulu futhi ilethe ukusebenza kahle okuphezulu kanye nokuthuthukiswa kwekhwalithi kumaphrojekthi ahlukahlukene okwakha obunjiniyela.
