Kukuliphi izinga lokushisa i-OPAIRi-screw air compressormotor umsebenzi evamile?
Ibanga le-insulation le-motor libhekisa ebangeni lokumelana nokushisa lezinto zokuvikela ezisetshenzisiwe, ezihlukaniswe ngamamaki A, E, B, F, kanye no-H.Ukwenyuka kwezinga lokushisa okuvumelekile kubhekisela emkhawulweni wezinga lokushisa lemoto uma kuqhathaniswa nezinga lokushisa elizungezile.
Ukukhuphuka kwezinga lokushisa kubhekisela enanini izinga lokushisa lokujika kwe-stator liphezulu kunezinga lokushisa elizungezile ngaphansi kwesimo sokusebenza esilinganiselwe semoto (izinga lokushisa le-ambient licaciswa njengokungu-35°C noma ngaphansi kuka-40°C, uma inani elithile lingamakwanga. ku-nameplate, ingu-40°C)
| Isigaba sokushisa kwe-insulation | A | E | B | F | H |
| Izinga lokushisa eliphezulu elivumelekile (℃) | 105 | 120 | 130 | 155 | 180 |
| Umkhawulo wezinga lokushisa elivunguzayo (K) | 60 | 75 | 80 | 100 | 125 |
| Izinga lokushisa lenkomba yokusebenza (℃) | 80 | 95 | 100 | 120 | 145 |
Emishinini kagesi njengamajeneretha, izinto zokuvikela i-insulating iyisixhumanisi esibuthakathaka.Izinto zokuvikela i-insulating zingenwa kalula izinga lokushisa eliphezulu kanye nokuguga okusheshayo nokulimala.Izinto ezihlukene zokuvikela ukushisa zinezindawo ezahlukene zokumelana nokushisa, futhi imishini kagesi esebenzisa izinto ezihlukene zokuvikela ingakwazi ukumelana Ikhono lokushisa eliphezulu lihlukile.Ngakho-ke, imishini kagesi evamile ibeka izinga lokushisa eliphezulu lomsebenzi wawo.
Ngokusho kwekhono lezinto ezihlukene zokuvikela ukumelana nokushisa okuphezulu, amazinga okushisa angu-7 aphezulu avunyelwe ashiwo kubo, ahlelwa ngokuhambisana nezinga lokushisa: Y, A, E, B, F, H no-C. Amazinga okushisa abo avumelekile okusebenza : Ngaphezulu kuka-90, 105, 120, 130, 155, 180 no-180°C.Ngakho-ke, ukufakwa kwe-Class B kusho ukuthi izinga lokushisa elimelana nokushisa le-insulation esetshenziswa ijeneretha lingu-130°C.Uma ijeneretha isebenza, umsebenzisi kufanele aqinisekise ukuthi impahla yokufakwa kwejeneretha ayidluli lelizinga lokushisa ukuze kuqinisekiswe ukusebenza okuvamile kwejeneretha.
Izinto zokuvalela ngaphakathi ezinekilasi B lokugquma zenziwe ikakhulukazi nge-mica, i-asbestos, nemicu yengilazi enamathiselwe noma efakwe ngeglue ephilayo.
I-OPPAIR screw air compressor
Umbuzo: Injini ingasebenza ngokujwayelekile kuliphi izinga lokushisa?Ingakanani izinga lokushisa eliphezulu elingamelana nemoto?
I-OPAIRi-screw air compressorIMPENDULO: Uma izinga lokushisa elilinganiselwe lekhava yemoto lidlula izinga lokushisa le-ambient ngaphezu kwamadigri angu-25, libonisa ukuthi ukukhuphuka kwezinga lokushisa kwemoto kudlule ibanga elivamile.Ngokuvamile, izinga lokushisa lemoto kufanele libe ngaphansi kwama-degree angu-20.Ngokuvamile, ikhoyili ye-motor yenziwe ngocingo olungenantambo, futhi lapho izinga lokushisa locingo olungenantambo liphakeme kunama-degree angama-150, ifilimu yopende izowa ngenxa yokushisa okuphezulu, okuholela ekujikelezeni okufushane kwekhoyili.Lapho izinga lokushisa ikhoyili lingaphezu kwama-degrees angu-150, izinga lokushisa le-motor casing lingama-degree angaba ngu-100, ngakho-ke uma kusekelwe ekushiseni kwayo kwe-casing, izinga lokushisa eliphezulu lemoto elingakwazi ukumelana nalo lingama-degree angu-100.
Q: Izinga lokushisa lenjini kufanele libe ngaphansi kwama-degree Celsius angama-20, okungukuthi, izinga lokushisa lesembozo sokuphela kwemoto kufanele lidlule izinga lokushisa elisendaweni engaphansi kwama-degree Celsius angama-20, kodwa kungani injini ishisa ngaphezu kwama-degree angama-20 Celsius?
I-OPAIRi-screw air compressorIMPENDULO: Lapho injini isebenza ngaphansi komthwalo, kuba nokulahlekelwa amandla emoteni, okuzoba amandla okushisa ekugcineni, okuzokhuphula izinga lokushisa lemoto futhi kudlule izinga lokushisa elizungezile.Inani izinga lokushisa lemoto liphakeme kakhulu kunezinga lokushisa le-ambient libizwa ngokuthi i-ramp-up.Uma izinga lokushisa likhuphuka, injini izokhipha ukushisa endaweni ezungezile;lapho izinga lokushisa liphakeme, ukuqeda ukushisa kuyashesha.Lapho ukushisa okukhishwa yi-motor ngesikhathi seyunithi kulingana nokushisa okuchithiwe, izinga lokushisa le-motor ngeke lisakhula, kodwa ligcine izinga lokushisa elizinzile, okungukuthi, esimweni sokulinganisela phakathi kwesizukulwane sokushisa nokushisa kokushisa.
Q: Kuyini ukukhuphuka kwezinga lokushisa okuvumelekile ngokuchofoza okujwayelekile?Iyiphi ingxenye yenjini ethinteka kakhulu ekukhuphukeni kwezinga lokushisa kwemoto?Ichazwa kanjani?
I-OPAIRi-screw air compressorA: Lapho injini isebenza ngaphansi komthwalo, kuyadingeka ukudlala indima yayo ngangokunokwenzeka.Umthwalo omkhulu, amandla okukhiphayo angcono (uma amandla omshini engacatshangwa).Kodwa lapho amandla okukhiphayo emakhulu, ukwehla kwamandla amakhulu, izinga lokushisa likhuphuka.Siyazi ukuthi into ebuthakathaka kakhulu kumotho yizinto ezivikelayo, njengocingo olunamele.Kunomkhawulo wokumelana nokushisa kwezinto zokuvikela.Ngaphakathi kwalo mkhawulo, izakhiwo ezingokomzimba, zamakhemikhali, zemishini, zikagesi nezinye zezinto ezigqugquzelwayo zizinze kakhulu, futhi impilo yazo yokusebenza ngokuvamile iyiminyaka engaba ngu-20.Ukweqa lo mkhawulo, impilo yezinto zokuvikela ifushaniswa ngokucijile, futhi ize ishise.Lo mkhawulo wokushisa ubizwa ngokuthi izinga lokushisa elivumelekile le-insulating material.Izinga lokushisa elivumelekile le-insulating impahla yizinga lokushisa elivumelekile le-motor;impilo yezinto zokuvikela ngokuvamile ukuphila kwenjini.
