Ngawaphi amaqondo obushushu anokuthi i-OPAIRicompressor yomoya jijaumsebenzi motor ngokuqhelekileyo?
Umgangatho wokugquma wemoto ubhekisa kwibakala lokumelana nobushushu bezinto ezisetyenziswayo zokugquma, ezahlulwe zaba ngamabakala A, E, B, F, kunye noH. Ukunyuka kweqondo lobushushu okuvumelekileyo kubhekiselele kumda wobushushu bemoto xa kuthelekiswa nobushushu bendawo.
Ukunyuka kobushushu kubhekiselele kwixabiso lokuba ubushushu be-stator winding buphezulu kunobushushu be-ambient phantsi komgangatho wokusebenza we-motor (ubushushu be-ambient buchazwe njenge-35 ° C okanye ngaphantsi kwe-40 ° C, ukuba ixabiso elithile aliphawulwanga kwi-nameplate, ngu-40 ° C)
| Iklasi yokushisa kwe-insulation | A | E | B | F | H |
| Elona qondo lobushushu livumelekileyo (℃) | 105 | 120 | 130 | 155 | 180 |
| Umoya wokunyuka kobushushu obumiselweyo (K) | 60 | 75 | 80 | 100 | 125 |
| Ubushushu bereferensi yokusebenza (℃) | 80 | 95 | 100 | 120 | 145 |
Kwizixhobo zombane ezifana neejenereyitha, izinto zokugquma i-insulating yiyona khonkco ibuthathaka. Izinto ezigqumayo zichaphazeleka ngakumbi kubushushu obuphezulu kunye nokuguga okukhawulezileyo kunye nomonakalo. Izinto ezahlukeneyo zokugquma zineendawo ezahlukeneyo zokumelana nobushushu, kunye nezixhobo zombane ezisebenzisa izinto zokugquma ezahlukeneyo zinokumelana Ikhono lobushushu obuphezulu lihlukile. Ke ngoko, izixhobo zombane ngokubanzi zichaza ubushushu obuphezulu bomsebenzi wayo.
Ngokwamandla ezinto ezahlukeneyo zokukhusela ukukhusela ukushisa okuphezulu, amaqondo angama-7 aphezulu avumelekileyo achazwe kubo, ahlelwe ngokuhambelana nobushushu: Y, A, E, B, F, H kunye noC. Ukushisa kwabo okuvumelekileyo okusebenzayo: Ngaphezulu kwe-90, 105, 120, 130, 155, 180 kunye ne-180 ° C. Ke ngoko, ukugqunywa kweKlasi B kuthetha ukuba ubushushu obunganyangekiyo bobushushu obusetyenziswa yijenereyitha yi-130°C. Xa i-generator isebenza, umsebenzisi kufuneka aqinisekise ukuba i-insulation generator material ayidluli eli bushushu ukuqinisekisa ukusebenza okuqhelekileyo kwejeneretha.
Izinto zokugquma nge-insulation class B zenziwa ikakhulu nge-mica, i-asbestos, kunye ne-glass filaments encanyathiselwe okanye ifakwe kwi-organic glue.
I-OPAIR Screw compressor yomoya
Umbuzo: Kubuphi ubushushu obunokuthi i-motor isebenze ngokuqhelekileyo? Leliphi elona qondo lobushushu liphezulu lemoto enokumelana nalo?
OPAIRicompressor yomoya jijaA: Ukuba iqondo lokushisa elilinganisiweyo le-motor cover lidlula ubushushu be-ambient ngaphezu kwe-25 degrees, kubonisa ukuba ukunyuka kweqondo lokushisa kwemoto kugqithise uluhlu oluqhelekileyo. Ngokuqhelekileyo, ukunyuka kwamaqondo obushushu bemoto kufuneka kube ngaphantsi kwama-20 degrees. Ngokuqhelekileyo, i-motor coil yenziwe nge-enameled wire, kwaye xa iqondo lokushisa locingo lwe-enameled liphezulu ngaphezu kwama-degrees angama-150, ifilimu yepeyinti iya kuwa ngenxa yokushisa okuphezulu, okubangelwa isiphaluka esifutshane sekhoyili. Xa ubushushu be-coil bungaphezulu kwama-degrees angama-150, iqondo lobushushu le-motor casing limalunga ne-100 degrees, ngoko ke ukuba isekelwe kubushushu be-casing yayo, ubushushu obuphezulu bemoto inokumelana ne-100 degrees.
Umbuzo: Iqondo lobushushu lemoto kufuneka libe ngaphantsi kwama-20 ngokukaCelsius, oko kukuthi, iqondo lobushushu lobushushu bemoto lifanele ligqithe iqondo lobushushu lendawo elikuyo ngaphantsi kwama-20 ngokukaCelsius, kodwa siyintoni isizathu esibangela ukuba injini ifudumale ngaphezu kwama-20 ngokukaCelsius?
OPAIRicompressor yomoya jijaA: Xa i-motor isebenza phantsi komthwalo, kukho ilahleko yamandla kwi-motor, eya kuthi ekugqibeleni ibe namandla obushushu, okuya kwandisa ubushushu bemoto kwaye kudlule ubushushu be-ambient. Ixabiso apho ubushushu bemoto buphezulu kunobushushu be-ambient libizwa ngokuba yi-ramp-up. Nje ukuba iqondo lobushushu linyuke, i-motor iya kukhupha ubushushu kwindawo eyingqongileyo; okukhona ubushushu buphezulu, kokukhona ukutshatyalaliswa kobushushu ngokukhawuleza. Xa ubushushu obukhutshwa yimoto ngexesha leyunithi lilingana nobushushu obuchithiweyo, ubushushu bemoto abuyi kuphinda bunyuke, kodwa bugcine ubushushu obuzinzileyo, oko kukuthi, kwimeko yolungelelwaniso phakathi kwesizukulwana sobushushu kunye nokutshatyalaliswa kobushushu.
Q: Yintoni ukunyuka kwamaqondo obushushu avumelekileyo ngokucofa ngokubanzi? Yeyiphi indawo yemoto echatshazelwa kakhulu kukunyuka kobushushu bemoto? Ichazwa njani?
OPAIRicompressor yomoya jijaA: Xa i-motor isebenza phantsi komthwalo, kuyimfuneko ukudlala indima yayo kangangoko kunokwenzeka. Umthwalo omkhulu, ungcono amandla okuvelisa (ukuba amandla omatshini angaqwalaselwa). Kodwa okukhona amandla aphumayo makhulu, kokukhona ukulahleka kwamandla, kokukhona kunyuka ubushushu. Siyazi ukuba eyona nto ibuthathaka kakhulu kwi-motor yimpahla yokugquma, njengocingo olunamele. Kukho umda wokumelana nobushushu bezinto zokukhusela. Kulo mda, izinto ezibonakalayo, iikhemikhali, oomatshini, umbane kunye nezinye izinto ze-insulating zizinzileyo kakhulu, kwaye ubomi babo bokusebenza ngokuqhelekileyo buneminyaka engama-20. Ukugqithisa lo mda, ubomi bezinto ezikhuselayo bufutshane ngokukhawuleza, kwaye zide zitshise. Lo mda weqondo lokushisa ubizwa ngokuba yiqondo lokushisa elivumelekileyo lezinto zokukhusela. Iqondo lokushisa elivumelekileyo lezinto ezikhuselayo liqondo lokushisa elivumelekileyo lemoto; ubomi bezinto ezigqumayo ngokuqhelekileyo bubomi benjini.
