Ruzivo rwekutanga rwemamota-anoputika
1. Mhando yemhando yemotokari inoputika
Pfungwa:Iyo inonzi inoputika-proof motor inoreva mota inotora mamwe matanho-ekudzivirira kuputika kuti ave nechokwadi chekuti inogona kushandiswa zvakachengeteka munzvimbo dzine njodzi dzinoputika.
Kuputika-proof motors inogona kukamurwa kuita matatu anotevera marudzi kana iwo akaumbwa mhando zvinoenderana nemisimboti yavo yekusangana inoputika-proof zvinodiwa:
1. Flameproof mhando, B mhando
Motokari isingakonzere kuputika kwekunze kwekuputika musanganiswa kana pakaitika kuputika mukati memotokari.Iyo mota casing ine yakakwana mechanical simba (yepamusoro-giredhi simbi yakakandwa, simbi ndiro senge casing), kuitira kuti ikwanise kumirisana nekuputika kwemhepo uye simba rekunze simba pasina kukuvara;Zvimiro zvimiro (gapu uye kureba) yenzvimbo inodzivirira moto;zvinodiwa pamabhokisi ejunction, waya inlet zvishandiso, nezvimwewo;kudzora tembiricha yeganda repamusoro kuitira kuti isasvike pakupisa kune njodzi.
2. Kuwedzera kuchengetedza mhando, mhando A
Kuiswa chisimbiso kwemota kuri nani, uye chiyero chekudzivirira chinodiwa cheIP55 chinogamuchirwa;iyo electromagnetic dhizaini inofanirwa kufunga kudzikisa kukwira kwekushisa;nguva iyo rotor inosvika pakupisa kune ngozi kana yakavharwa, uye yakagadzirirwa nemagetsi ekuzvidzora;kunatsiridza kutendeuka-kutendeuka, pasi-kusvika-pasi uye nhanho-kune-chikamu bvunzo dzemhepo inovhara insulation voltage;kunatsiridza kuvimbika kwekubatanidza conductor;kudzora hushoma unilateral clearance ye stator uye rotor.Muchidimbu, inodzivirira sparks netsaona, arcs kana tembiricha ine njodzi kubva kune zvimiro uye zvemagetsi zvinhu, nekudaro zvinovandudza kuchengetedzwa kwekushanda.
3. Positive pressure type, P type
Motokari inodzivirira kuputika inopinza mweya wakanaka mudzimba kana kuizadza negasi inert (senge nitrogen) kudzivirira masanganiswa anoputika ekunze kupinda mumota.
Kuwanda kwekushandisa:Flameproof uye yakanaka kudzvanywa mhando dzakakodzera kune ese anoputika ane ngozi nzvimbo, uye anopisa moto mota ( Type B.) anoshandiswa zvakanyanya muChina.Mutengo wekugadzira uye mutengo weiyo yakawedzera yekuchengetedza mota yakaderera pane iyo yemhando yemoto, uye inokodzera Zone chete.2 nzvimbo.
2. Kupatsanurwa kwemamota mumhepo inoputika gasi
1. Maererano nekurongwa kwenzvimbo dzekuputika
| Kurongwa kwenzvimbo dzekuputika | zone0 | Ruwa1 | Zone2 |
| Frequency uye nguva yemhepo inoputika gasi | Nzvimbo dzine gasi rinoputika rinoonekwa richiramba riripo kana kuti riripo kwenguva yakareba | Nzvimbo dzinogona kuitika gasi rinoputika panguva yekushanda kwakajairika | Panguva yekushanda kwakajairika, hazvigoneke kuve nenzvimbo inoputika gasi, kana nzvimbo yainooneka nguva nenguva uye inongovapo kwenguva pfupi. |
2. Maererano nerudzi rwegasi rinoputika
| kuputika kwemhepo Kurongeka kwemidziyo yemagetsi | Kirasi I Midziyo yeMagetsi yemugodhi wemarasha | Kirasi II Midziyo yemagetsi yemhepo inoputika gasi kunze kwemigodhi yemarasha | ||
| II A | II B | II C | ||
| Inoshanda gasi nharaunda | methane | Anopfuura zana marudzi e toluene, methanol, ethanol, dhiziri, nezvimwe. | Vanenge makumi matatumarudzi eethylene, gasi, nezvimwewo. | Hydrogen, acetylene, carbon disulfide, nezvimwewo. |
3. Yakarongedzerwa maererano nekupisa kwechisikigo kwegasi rinoputika
| tembiricha boka | Kunyanya tembiricha yepamusoro °C | media type |
| T1 | 450 | Toluene, Xylene |
| T2 | 300 | Ethylbenzene, nezvimwewo. |
| T3 | 200 | Diesel, nezvimwewo. |
| T4 | 135 | Dimethyl etheretc. |
| T5 | 100 | carbon disulfide nezvimwe. |
| T6 | 85 | Ethyl nitrite, nezvimwewo. |
3. Zviratidzo zvinoputika zvemamotor-proof-proof
1. Mienzaniso yezvibodzwa zvisingaputse zvemamota asingatsva-chikamu matatu-asynchronous motors:
ExDI inodzivirira moto mota yemugodhi wemarasha
ExD IIBT4 fekitori IIBod T4 boka rakadai se: tetrafluoroethylene nzvimbo
2. Mienzaniso yezviratidzo zvinoputika zvekuwedzera kuchengetedzwa kwematatu-chikamu asynchronous motors:
ExE IIT3 inoshanda kune nzvimbo dzinopisa tembiricha iri T3 boka rinopisa gasi mufekitori.
4. Zvitatu zvekupihwa zvitupa zvinodikanwa zvemamotor anoputika
Kana mota inoputika-inobuda mufekitori, kuita kwayo kunofanirwa kusangana nezvinodiwa zvehunyanzvi mamiriro uye zviyero, uye inofanirwawo kuwana zvitupa zvitatu zvakapihwa nemadhipatimendi akakodzera ehurumende.Iyo mota nameplate inofanirwa kuratidza nhamba nhatu dzechitupa, dzinoti:
1. Chitupa-chisina kuputika
2. Kuputika-uchapupu mota yekugadzira rezinesi nhamba
3. Chekuchengetedza chitupa MA nhamba.
Panofanira kunge paine mutsvuku EX mucherechedzo pakona yepamusoro yekurudyi yemota nameplate uye pachivharo chebhokisi rekuburitsa.
