Ulwazi olusisiseko lwee-motor-proof-proof motors
1. Imodeli yohlobo lwemoto olungaqhushumba
Ingcamango:Into ebizwa ngokuba yi-motor-proof-proof ibhekisela kwi-motor ethatha amanyathelo athile okuthintela ukuqhuma ukuqinisekisa ukuba inokusetyenziswa ngokukhuselekileyo kwiindawo ezinobungozi bokudubula.
Iimoto ezinobungqina bokudubula zinokwahlulwa zibe zezi ntlobo zintathu zilandelayo okanye iintlobo zazo eziyintlanganisela ngokwemigaqo yazo esisiseko yokuhlangabezana neemfuno zobungqina bokudubula:
1. Uhlobo lwe-flameproof, uhlobo lwe-B
I-motor engabangeli ukuqhuma komxube oqhumayo wangaphandle xa kwenzeka ukuqhuma ngaphakathi kwemoto.I-motor casing inamandla okwaneleyo omatshini (i-high-grade cast iron, i-steel plate njenge-casing), ukwenzela ukuba ikwazi ukumelana noxinzelelo lokuqhuma kunye nempembelelo yamandla angaphandle ngaphandle komonakalo; Iiparamitha zesakhiwo (i-gap kunye nobude) bendawo edibeneyo yomlilo; iimfuno zeebhokisi zesiphambuka, izixhobo zokungena ngocingo, njl.; lawula ubushushu bomphezulu weqokobhe ukuze lingakwazi ukufikelela kubushushu obunobungozi.
2. Uhlobo lokhuseleko olwandisiweyo, uhlobo A
Ukutywinwa kwe-motor kungcono, kwaye iimfuno zomgangatho wokukhusela we-IP55 zamkelwe; uyilo lwe-electromagnetic kufuneka luthathele ingqalelo ukunciphisa ukunyuka kobushushu; ixesha apho i-rotor ifikelela kwiqondo lokushisa eliyingozi xa ivaliwe, kwaye ixhotywe ngesixhobo sombane esizilawulayo; ukuphucula i-turn-to-turn, i-ground-to-ground kunye nesigaba-to-isigaba sovavanyo lombane wokugquma; ukuphucula ukuthembeka koqhagamshelo lomqhubi; lawula ubuncinci be-unilateral clearance ye-stator kunye ne-rotor.Ngamafutshane, ikhusela iintlantsi zengozi, ii-arcs okanye amaqondo okushisa ayingozi ukusuka kwisakhiwo kunye nemiba yombane, ngaloo ndlela iphucula ukhuseleko lokusebenza.
3. Uhlobo loxinzelelo oluhle, uhlobo lwe-P
I-motor-proof-proof motor efaka umoya omtsha opholileyo kwindlu okanye iyigcwalise ngegesi engasebenziyo (efana nenitrogen) ukunqanda imixube eqhumayo yangaphandle ukuba ingangeni kwinjini.
Ubungakanani bosetyenziso:Iintlobo zoxinzelelo oluvuthayo kunye noxinzelelo olufanelekileyo zilungele zonke iindawo ezinobungozi eziqhumayo, kunye neenjini ezingatshiyo (Udidi B) zisetyenziswa kakhulu eTshayina.Iindleko zokwenziwa kunye nexabiso lemoto eyonyusiweyo yokhuseleko isezantsi kunezo zohlobo olungatshiyo, kwaye zilungele kuphela uMmandla.iindawo ezi-2.
2. Ukuhlelwa kweenjini kwi-atmospheres yerhasi eqhumayo
1. Ngokohlelo lweendawo eziqhushumbayo
| Ukuhlelwa kweendawo zogqabhuko-dubulo | indawo0 | Isithili1 | Zowuni2 |
| Ukuphindaphinda kunye nobude bomoya werhasi eqhumayo | Iindawo apho i-atmospheres yerhasi eqhumayo ibonakala ngokuqhubekayo okanye ikhona ixesha elide | Iindawo apho i-atmospheres yerhasi eqhumayo inokuthi yenzeke ngexesha lokusebenza kwesiqhelo | Ngexesha lokusebenza okuqhelekileyo, akunakwenzeka ukuba kubekho indawo yegesi eqhumayo, okanye indawo apho ibonakala khona ngamaxesha athile kwaye ikhona kuphela ixesha elifutshane. |
2. Ngokohlobo lwerhasi eqhumayo
| umoya oqhumayo Ukuhlelwa kwezixhobo zombane | Iklasi I Izixhobo zoMbane zoMgodi wamalahle | Udidi II Izixhobo zombane zegesi eqhumayo emoyeni ngaphandle kwemigodi yamalahle | ||
| II A | II B | II C | ||
| Indawo yegesi esebenzayo | imethane | Ngaphezulu kwe-100 yeentlobo ze-toluene, i-methanol, i-ethanol, idizili, njl. | Phantse ngama-30iintlobo zeethylene, igesi, njl. | I-Hydrogen, i-acetylene, i-carbon disulfide, njl. |
3. Ihlelwa ngokobushushu bendalo berhasi eqhumayo
| iqela lobushushu | Elona qondo lobushushu bomphezulu °C | uhlobo lwemidiya |
| T1 | 450 | Toluene, Xylene |
| T2 | 300 | Ethylbenzene, njl. |
| T3 | 200 | Idizili, njl. |
| T4 | 135 | Idimethyl ethernjl. |
| T5 | 100 | carbon disulfide njl. |
| T6 | 85 | I-Ethyl nitrite, njl. |
3. Iimpawu ezikhusela uqhushumbo kwiinjini ezikwazi ukudubula
1. Imizekelo yamanqaku angangenwa luqhushumbo kwiimotor ezinezigaba ezithathu ezingatshiyo:
Imoto ye-ExDI engatshiyo yomgodi wamalahle
ExD IIBT4 umzi-mveliso IIBod T4 iqela ezifana: tetrafluoroethylene indawo
2. Imizekelo yamanqaku angangenwa luqhushumbo okhuseleko olwandisiweyo lweemotor ezinenqanaba lesithathu:
I-ExE IIT3 iyasebenza kwiindawo apho iqondo lobushushu liyi T3 yeqela elinokutsha kumzi-mveliso.
4. Iimfuno ezintathu zoqinisekiso lweemoto ezingaqhushumba
Xa i-motor-proof-proof ishiya umzi-mveliso, ukusebenza kufuneka kuhlangabezane neemfuno zeemeko zobugcisa kunye nemigangatho, kwaye kufuneka kwakhona ukufumana izatifikethi ezithathu ezikhutshwe ngamasebe afanelekileyo karhulumente. Icwecwe lemoto kufuneka libonise amanani amathathu esatifikethi, angala:
1. Isatifikethi sobungqina bokudubula
2. Inombolo yelayisenisi yokuvelisa iimoto engenakuqhushumba
3. Inombolo yesiqinisekiso sokhuseleko ye-MA.
Kufuneka kubekho uphawu olubomvu lwe-EX kwikona ephezulu ngasekunene ye-nameplate yemoto kunye nakwiqweqwe lebhokisi yokuphuma.
