Izibani ze-alamu zomshini we-CNCziyizibonakaliso ezibalulekile zesexwayiso sokuphepha ngesikhathi sokusebenza kwamathuluzi omshini we-CNC. Zazisa opharetha ngesimo sokusebenza kwemishini ngempendulo ezwakalayo (njengemisindo yokukhala noma imisindo yesixwayiso). Ukuthi umsindo wokukhanya kwe-alamu ujwayelekile yini kuhlobene ngqo nokuthi amaphutha emishini angatholakala ngokushesha, okuqinisekisa ukusebenza okuphephile kwamathuluzi omshini. Umsindo wokukhanya kwe-alamu ongajwayelekile, njengokungabikho komsindo noma umsindo oqhubekayo, awuthinti nje kuphela ukusebenza kahle kokulungisa kodwa futhi ungase ube yingozi yokuphepha. Lesi sihloko sizochaza izimpawu zomsindo wokukhanya kwe-alamu ongajwayelekile futhi sinikeze inqubo yokuxazulula izinkinga ehlelekile kanye nokulungisa ukusiza abasebenzi bokulungisa imishini ukuxazulula izinkinga ngempumelelo nokuqinisekisa ukusebenza okuzinzile kwamathuluzi omshini.
Izimpawu Ezivamile Nokuxazulula Izinkinga Zomsindo Wokukhanya Ongajwayelekile We-Alarm
Umsindo wokukhanya kwe-alamu ongajwayelekile uvame ukuvela ngezindlela ezintathu:
· Akukho msindo: Lokhu kuvame ukubangelwa isixhumanisi sokukhipha umsindo esingaxhunyiwe noma inkinga yokunikezwa kwamandla.
· Umsindo noma ukuhlanekezela: Lokhu kuvame ukubangelwa ukuguga noma ukulimala kwezingxenye ezikhiqiza umsindo njenge-buzzer noma isikhulumi, noma i-voltage kagesi engazinzile.
· Umsindo ongapheli noma ongaqhubeki: Lokhu kuvame ukubangelwa ukuxhumana okungekuhle noma uxhumano olungazinzile emugqeni wokudlulisa isignali.
Ngaphezu kwalokho, ukunquma ububanzi bomsindo ongajwayelekile kubalulekile. Ingabe inkinga yenzeka kuphela ezimweni ezithile ze-alamu, njenge-alamu yokuma okuphuthumayo noma i-alamu yokulayisha ngokweqile? Noma ingabe umsindo ongajwayelekile uvame kuwo wonke ama-alamu? Uma amanye ama-alamu ezwakala ngokungajwayelekile, kungase kube nenkinga nge-logic yesistimu ye-alamu noma izinzwa ezihlobene. Uma wonke ama-alamu ezwakala ngokungajwayelekile, kungase kube nenkinga ngehadiwe yesibani se-alamu noma uhlelo lokunikezwa kwamandla. Ukucacisa lezi zinkinga kuzosiza ukunciphisa ububanzi bophenyo futhi konge isikhathi.
Izinyathelo ezihlelekile zokuxazulula izinkinga zomsindo wokukhanya kwe-alamu
1. Hlola ukunikezwa kwamandla kanye nemigqa yesiginali
Imojula yomsindo wesibani se-alamu kumele ithembele ekuhlinzekweni kwamandla okuzinzile, ngakho-ke umsebenzi wokuqala ukuqinisekisa ukuhlinzekwa kwamandla. Abasebenzi bokulungisa kufanele baqale bacime ukuhlinzekwa kwamandla okuyinhloko komshini bese besebenzisa i-multimeter ukukala i-voltage kuma-terminal kagesi esibani se-alamu, ngokuvamile angu-24V DC. Uma i-voltage ingakhombisi i-voltage noma ukushintshashintsha okuphawulekayo, isinyathelo esilandelayo ukuhlola i-fuse evuvukile noma i-oxidation kuma-contact e-contactor. I-fuse evuvukile kufanele ishintshwe ngokushesha, kuyilapho ama-contact e-oxidized kufanele ahlanzwe nge-sandpaper encane futhi aqiniswe kabusha ukuqinisekisa ukuthi axhumana kahle.
Okulandelayo, landela ikhebula lesignali elixhumanisa isibani se-alamu bese uhlola izintambo nezixhumi kusukela kubhulokhi yesibani se-alamu kuze kube yi-module yokukhipha ye-PLC noma iyunithi yokulawula i-alamu.Umshini we-CNCkungakhulula noma kulimaze kalula izixhumi zekhebula. Ukuvikela okonakele nakho kungaletha ukuphazamiseka, okubangela ukungasebenzi kahle kwesignali. Ngesikhathi sokulungisa, hlola ingxenye ngayinye ngayinye, xhuma kabusha ama-terminal, bese uqinisa izikulufo zokuxhuma ukuqinisekisa ukuthi izintambo zisesimweni esihle nokuthi ukuvikela kuphelele.
2. Ukuhlolwa Kwehadiwe Nokushintshwa Kwezingxenye Zomsindo
Ngemva kokuqinisekisa ukuthi imigqa yamandla kanye nezimpawu zivamile, i-buzzer noma isikhulumi esingaphakathi kwesibani se-alamu singase sibe nenkinga. Ngemva kokucima isibani se-alamu, hlukanisa isibani se-alamu bese uhlola ngokubonakalayo ingxenye ezwakalayo ukuze ubone umonakalo osobala, njenge-diaphragm ephukile noma ikhoyili eshisiwe. Uma ukubukeka kujwayelekile, sebenzisa i-multimeter ukuze ulinganise ukumelana kwengxenye ezwakalayo. Inani lokumelana okungavamile (eliphezulu kakhulu noma eliseduze no-zero) libonisa ukwehluleka kwengxenye.
Uma ushintsha izingxenye, qiniseka ukuthi imininingwane ye-voltage yengxenye entsha kanye nobukhulu bokufaka kufana nobudala. Ngesikhathi sokufakwa, naka kakhulu i-polarity ukuze ugweme ukuxhumana okuphambene, okungadala umonakalo wesibili. Ukukhetha izingxenye ezifanelekile kuqinisekisa ukusebenza okuzinzile kwesikhathi eside nokwesikhathi eside kwesibani se-alamu.
3. Qinisekisa amapharamitha esistimu ye-PLC kanye ne-Alarm Logic
Uma ihadiwe ingasebenzi, isinyathelo esilandelayo ukuqinisekisa izilungiselelo ze-alamu ohlelweni lokulawula amathuluzi omshini. Sebenzisa isikhombimsebenzisi sokuhlela se-PLC noma ikhasi lezilungiselelo zepharamitha ukuhlola ukuthi umsindo we-alamu uyasebenza yini. Amanye amathuluzi omshini avumela umsindo we-alamu ukuthi uthuliswe, okungabangela ukuthi ukukhanya kwe-alamu kuthule. Kubalulekile futhi ukuqinisekisa ukuthi imiphumela ye-PLC yezinhlobo ezahlukene ze-alamu isebenza kahle. Isibonelo, ukuthi umkhiqizo we-PLC we-alamu yokumisa ephuthumayo ungabangela umsindo we-alamu. Uma i-PLC ingaphenduli, hlola inkinobho yokumisa ephuthumayo kanye nezinzwa ezihlobene ukuze ubone ukuthi kukhona iphutha engxenyeni yokuqalisa engaphambili.
Eminye imishini ingalungisa ivolumu kanye nemvamisa yomsindo we-alamu. Uma umsindo ubuthakathaka noma uphambene, buyisela izilungiselelo ezizenzakalelayo bese ulungisa kabusha amapharamitha ukuqinisekisa umsindo ocacile nosebenzayo.
Ukuqinisekiswa Kokusebenza Ngemva Kokulungiswa kanye Nezincomo Zokulungisa Okuvamile
Ngemva kokulungisa, qiniseka ukuthi ulingisa izimo ezahlukahlukene ze-alamu ukuze kuqinisekiswe, njengokucindezela inkinobho yokumisa eziphuthumayo noma ukwenza isivivinyo sokulayisha ngokweqile, ukuqinisekisa ukuthi umsindo wokukhanya kwe-alamu ucacile futhi uzinzile. Amarekhodi anemininingwane yembangela yephutha kanye nenqubo ethile yokulungisa kufanele afakwe efayeleni lokulungisa imishini ukuze kubhekwe kulo ngesikhathi sokulungisa okulandelayo.
Ukuze kuncishiswe ukwanda kwemisindo yokukhanya kwe-alamu engajwayelekile, kunconywa ukuthi kusungulwe uhlelo lokulungisa olujwayelekile. Hlola ukuxhumeka kwezintambo kanye nokuqina kwesibani se-alamu okungenani njalo ngenyanga ukuze uvimbele ukukhululeka ngenxa yokudlidliza kwemishini. Ngaphezu kwalokho, lapho uhlanza i-alamuIsikhungo sokujika se-CNC, qaphela ukuvimbela amanzi namafutha ukuthi angangeni ekukhanyeni kwe-alamu kanye nomswakama ekulimazeni izingxenye ezikhalayo. Uma izingxenye zitholakala ukuthi ziyaguga, ukushintshwa ngesikhathi kubalulekile ukuqinisekisa ukusebenza kahle kwesikhathi eside kohlelo lwe-alamu.
Ngokusungula umjikelezo wokulungisa ohlelekile "wokuxazulula izinkinga - ukulungisa - ukuqinisekisa - ukuvimbela," akugcini nje ngokuthuthukiswa kokuthembeka komsindo wesibani se-alamu, kodwa futhi kungathuthukisa kakhulu amakhono okuxwayisa ngokuphepha ethuluzi lomshini, kuqinisekiswe ukukhiqizwa okubushelelezi.
Isiphetho
Ukuphazamiseka kokukhanya kwe-alamu kungabonakala kuncane, kodwa kubalulekile emsebenzini oyinhloko wesistimu yesixwayiso sokuphepha sethuluzi lomshini. Inqubo yokulungisa kufanele ilandele isimiso esithi "kulula kuqala, kunzima kamuva, ihadiwe kuqala, isofthiwe kamuva," ukukhomba iphuzu lephutha isinyathelo ngesinyathelo, kusukela ekuxhunyweni kwamandla kagesi kanye nokudluliselwa kwesignali kuya kuzilungiselelo zehadiwe nesistimu ezizwakalayo. Kungale ndlela kuphela lapho umsebenzi womsindo wesibani se-alamu ungabuyiselwa ngokushesha, isivinini sokuphendula iphutha lethuluzi lomshini we-CNC singathuthukiswa, kanye nokuphepha kokukhiqiza kuqinisekiswe. Abasebenzi bokulungisa akumele nje babe yizingcweti zezindlela zokulungisa zesayensi kodwa futhi baphinde benze njalo ukulungiswa kokuvimbela ukuze banciphise kakhulu ukwenzeka kokwehluleka nokuqinisekisa ukusebenza okuphephile nokusebenza kahle komshini we-CNC.
