ubuchwepheshe obukhulu | Imboni entsha | Feb 27.2025
Njengengxenye ebalulekile yokudlulisa amandla nezimpawu emishinini yezimboni, ukukhethwa kwezindandatho zokushelela zekhebula kuthinta ngqo ukuzinza kwesikhathi eside nokuphepha kwemishini. Kodwa-ke, ekuthengweni kwangempela, onjiniyela noma abathengi abaningi bavame ukuwela ekungaqondani kokukhetha ngenxa yokuqonda okunganele kwemingcele yobuchwepheshe, okuholela ekuhlulekeni kwemishini njalo ngisho nezingozi zokuphepha. Lesi sihloko sizoxazulula ukungaqondani okuningana okuvamile ukukusiza uhambisane nezidingo zakho ngokunembile, ikakhulukazi amaphuzu ayinhloko ahilelaIzindandatho zokushelela zokuvikela ze-IP68futhiindandatho yokushelela engaqhumiumthamo wamanje.
Umbono Oyiphutha 1: Unganaki izinga lokuvikelwa kwemvelo bese ukhetha imodeli evamile ngokunganaki
Abasebenzisi abaningi bakholelwa ukuthi "uma izinga lokuvikela lendandatho yokushelela liphezulu, izindleko ziyoncipha kakhulu", ngakho-ke bavame ukukhetha imodeli yokuvikela ephansi ezindaweni ezingezona ezeqile. Kodwa-ke, lo mbono awukunaki ubunzima bezimo zezimboni. Isibonelo, echwebeni elivulekile noma e-workshop enothuli, uma indandatho yokushelela yokuvikela ye-IP68 ingasetshenziswa, umhwamuko wamanzi noma izinto ezincane zingangena endandatho yokushelela, okubangela ukubola kwendawo yokuxhumana kanye nokuphazamiseka kwesignali. Isiphakamiso: Qondanisa ngokuqinile izinga lokuvikela ngokuya ngendawo yokuthunyelwa kwemishini. Isibonelo, indinganiso ye-IP68 kumele ikhethwe ezindaweni ezinomswakama nezinothuli, kuyilapho i-IP65 ingakhethwa ezindaweni zokusebenzela ezivamile.
Umbono Oyiphutha 2: Umthamo wamanje wama-slip rings angangeni ukuqhuma ubhekisela kuphela kumapharamitha angaguquki
Ezimweni ezingamelani nokuqhuma (njengemboni yamakhemikhali kanye nezimayini), abasebenzisi bavame ukukhetha ngqo imodeli ngokusekelwe kumthamo wamanje ojwayelekile wamasongo angaguquki, kodwa banganaki umthelela wezimo zokusebenza eziguquguqukayo. Isibonelo, inani eliphakeme lamanje ngesikhathi sokuqala nokuma kwemishini lingadlula kakhulu inani elilinganiselwe, futhi ukugcwala ngokweqile kwesikhathi eside kuzosheshisa ukuguguleka kwendandatho yokuguguleka futhi kubangele ngisho nezingozi zokuphepha.
Incazelo yecala: Iqembu lezimayini lake lakhetha izindandatho zokushelela ezinomthamo wamanje "owawusanda kufinyelela izinga", okwabangela ukukhubeka kwemishini njalo. Ngemva kokuhlola, kwatholakala ukuthi umfutho wamanje osheshayo ekusebenzeni kwangempela ufinyelele inani elijwayelekile ngokuphindwe ka-1.5, futhi inkinga ekugcineni yaxazululwa ngokufaka esikhundleni imodeli yamandla aphezulu.
Umbono Ongeyiwo 3: Ukudideka kwezindinganiso zezinga ezingaqhumi kanye nokwahlulela kabi izimo zokusetshenziswa
Abanye abasebenzisi bakholelwa ukuthi "ingaqhumi = yonke indawo", bengazinaki izimo ezifanele zezindinganiso ezahlukene ezingaqhumi. Isibonelo, izindawo ezisebenzayo ze-Ex d (engaqhumi umlilo) kanye ne-Ex e (ukuphepha okwandisiwe) zihluke kakhulu. Uma imodeli engaguquki ikhethwe ngephutha endaweni enegesi evuthayo, kungase kwenzeke izingozi ezinkulu.
Amaphuzu abalulekile: Izindandatho zokushelela ezingaqhumi kumele zihlangabezane nomthamo wamanje kanye nezitifiketi zemvelo (njenge-ATEX, i-IECEx), futhi zihlukanise ngokuqinile amaqembu egesi kanye namazinga okushisa.
Umbono Ongalungile 4: Ukunganaki umehluko phakathi kwamapharamitha aguquguqukayo namapharamitha angaguquki
"Ukumelana kokuthintana okuguqukayo" kanye "nokumelana kokuthintana okumile" kwama-slip rings kuvame ukudidaniswa. Ama-slip rings asebenza kahle ekuhlolweni okumile angabangela ukuguquguquka kokumelana ngenxa yokudlidliza lapho ejikeleza ngesivinini esikhulu, okuthinta ukunemba kokudluliselwa kwesignali. Lokhu kubaluleke kakhulu ezimweni ezinembe kakhulu njengemigqa yokukhiqiza ezenzakalelayo.
Isixazululo: Kudingeka abahlinzeki banikeze imibiko yokuhlola isimo sokusebenza esishintshashintshayo, begxile ekuqineni kokumelana kanye nama-life curve.
Umbono Oyiphutha 5: Ukuphishekela ngokweqile amanani aphansi, ukunganaki ubuchwepheshe bomkhiqizo kanye nensizakalo yangemva kokuthengisa
Nakuba izindandatho zokushelela ezishibhile zingonga izindleko zesikhashana, izinto ezisezingeni eliphansi (njengokungeneli kwegolide) zingabangela ukuguguleka kwangaphambi kwesikhathi kwezindawo zokuxhumana. Ngaphezu kwalokho, izinhlobo ezingenalo ukwesekwa kobuchwepheshe zingase zingakwazi ukunikeza izinsizakalo ezenziwe ngokwezifiso (njengokwenza ngcono isakhiwo sokuvalela izindandatho zokushelela ezivikelayo ze-IP68).
Idatha yemboni: Ngokwezibalo, ukulahleka kwesikhathi sokungasebenzi kwemishini okubangelwa ukwehluleka kwendandatho yokushelela kuvame ukuphindwe kayishumi kunezindleko zokuthenga zendandatho yokushelela.
Isiphetho
Ukukhethwa kwezindandatho zokushelela zekhebula kudinga ukucabangela ngokuphelele amapharamitha anobukhulu obuningi njengokuvikelwa kwemvelo, umthwalo oguquguqukayo, kanye nezindinganiso zokuvikela ukuqhuma. Kumasongo okushelela okuvikela i-IP68, ukuvalwa kwesikhathi eside kudinga ukuqinisekiswa; futhi kumthamo wamanje wendandatho yokushelela okuvikela ukuqhuma, kudingeka kugodlwe isilinganiso sokuphepha esingaphezu kuka-20%. Kunconywa ukubambisana nabaphakeli abanolwazi lobunjiniyela ukuze kugwenywe izingozi ezingaba khona ngokusebenzisa idatha elinganisiwe kanye nokulingisa isimo ukuqinisekisa ukusebenza kwesikhathi eside nokuzinzile kwemishini.
Imibuzo Evame Ukubuzwa
Q: Ingabe izindandatho zokuvikela ze-IP68 zifanelekile ezindaweni ezingaphansi kwamanzi?
A: I-IP68 imelela kuphela izinga eliphezulu kakhulu lokumelana nothuli namanzi, kodwa ukucwiliswa emanzini isikhathi eside kudinga ukuqinisekiswa okwengeziwe kokumelana nokugqwala kwezinto.
Q: Ungabala kanjani amandla amanje ezindandatho zokushelela ezingaqhumi?
A: Kudingeka ukuhlolwa okuphelele ngokusekelwe kumandla amanje aphezulu, isikhathi sokusebenza esiqhubekayo kanye nezimo zokushabalalisa ukushisa. Kunconywa ukubhekisela kumazinga e-IEC 60079.
U: Ingabe impilo yendandatho yokushelela ihlobene nesivinini?
A: Yebo, isivinini esikhulu sizokwandisa ukuguguleka, futhi inani lokuzibophezela empilweni ngesivinini esiphezulu kumele lihambisane lapho ukhetha.
