Kusehlobo, futhi ngalesi sikhathi, amaphutha okushisa aphezulu weair compressorszivamile.Lesi sihloko sifingqa izimbangela ezihlukahlukene ezingenzeka zokushisa okuphezulu.
1. I-air compressor system ishoda ngamafutha.
Izinga likawoyela likawoyela negesi lingabhekwa.Ngemuva kokuvala shaqa nokucindezela, lapho amafutha okugcoba ephumulile, izinga likawoyela kufanele libe phezulu kancane kunophawu lwezinga eliphezulu likawoyela (umugqa obomvu ngenhla).Ngesikhathi sokusebenza kwemishini, izinga likawoyela alikwazi ukuba ngaphansi kophawu oluphansi lwamafutha (umugqa obomvu ngezansi).Uma kutholakala ukuthi ubuningi bamafutha ayanele noma izinga likawoyela alikwazi ukubonwa, misa umshini ngokushesha bese ufaka uphethiloli.
2. Ivalvu yokumisa uwoyela (ivalve yokusika uwoyela) ayisebenzi kahle.
I-valve yokumisa uwoyela ngokuvamile iyi-valve ye-solenoid enezindawo ezimbili evamise ukuvala, evulwa lapho iqala futhi ivaliwe lapho imiswa, ukuze kuvinjwe uwoyela osemgqonyeni kawoyela negesi ukuthi ungaqhubeki ufutha ekhanda lomshini futhi fafaza uphume endaweni yokungenisa umoya lapho umshini umiswa.Uma ingxenye ingavulwa ngesikhathi sokulayisha, injini eyinhloko izoshisa ngokushesha ngenxa yokuntuleka kwamafutha, futhi ezimweni ezinzima, umhlangano wesikulufa uzoshiswa.
3. Inkinga yokuhlunga uwoyela.
A: Uma isihlungi samafutha sivalekile futhi i-valve ye-bypass ingavulwa, i-i-compressor yomoyauwoyela awukwazi ukufinyelela ekhanda lomshini, futhi injini enkulu izoshisa ngokushesha ngenxa yokuntuleka kwamafutha.
B: Isihlungi sikawoyela sivalekile futhi izinga lokugeleza liba lincane.Kunesimo sokuthi i-compressor yomoya ayisuswanga ngokuphelele ukushisa, futhi izinga lokushisa le-compressor yomoya likhuphuka kancane ukuze lenze izinga lokushisa eliphezulu.Esinye isimo izinga lokushisa eliphezulu le-compressor yomoya ngemva kokwehliswa kwe-compressor yomoya, ngoba ukucindezela kwamafutha kwangaphakathi kwe-compressor yomoya kuphezulu uma i-compressor yomoya ilayishwa, uwoyela we-compressor womoya ungadlula, futhi umfutho wamafutha we-compressor emoyeni iphansi ngemva kokulayishwa kwe-compressor yomoya.Isihlungi samafutha se-compressor yomoya sinzima, futhi izinga lokugeleza lincane kakhulu, okubangela ukushisa okuphezulu kwe-compressor yomoya.
4. I-valve yokulawula ukushisa (i-valve yokulawula izinga lokushisa) ayisebenzi kahle.
I-valve yokulawula ukushisa ifakwe phambi kwe-cooler yamafutha, futhi umsebenzi wayo ukugcina izinga lokushisa lokukhipha ikhanda lomshini ngaphezu kwendawo yamazolo yokucindezela.
Isimiso sayo sokusebenza siwukuthi ngenxa yokushisa kwamafutha aphansi lapho uqala, isifunda segatsha se-valve yokulawula ukushisa sivuliwe, isifunda esikhulu sivaliwe, futhi amafutha okugcoba afafazwe ngokuqondile ekhanda lomshini ngaphandle kokupholisa;lapho izinga lokushisa likhuphuka ngaphezu kuka-40 ° C, i-valve yokulawula ukushisa ivalwa kancane kancane, Amafutha ageleza endaweni epholile kanye negatsha ngesikhathi esifanayo;lapho izinga lokushisa likhuphuka ngaphezu kuka-80 ° C, i-valve ivalwe ngokuphelele, futhi wonke amafutha okugcoba adlula endaweni epholile bese engena ekhanda lomshini ukuze apholise amafutha okugcoba ngezinga elikhulu kakhulu.
Uma i-valve yokulawula ukushisa ihluleka, amafutha okugcoba angangena ngokuqondile ekhanda lomshini ngaphandle kokudlula endaweni epholile, ukuze izinga lokushisa likawoyela lingancishiswa, okuholela ekushiseni ngokweqile.
Isizathu esiyinhloko sokwehluleka kwayo ukuthi i-coefficient of elasticity of the two heat-sensitive spring on the spool ishintsha ngemva kokukhathala, futhi ayikwazi ukusebenza ngokujwayelekile ngokushintsha kwezinga lokushisa;okwesibili ukuthi umzimba we-valve ugqokile, i-spool ibambekile noma isenzo asikho endaweni futhi ayikwazi ukuvalwa ngokujwayelekile.Ingakhandwa noma ishintshwe ngendlela efanele.
5. Isilawuli sevolumu yamafutha asijwayelekile, futhi umthamo womjovo kaphethiloli unganyuswa ngokufanelekile uma kunesidingo.
Umthamo womjovo kaphethiloli ulungisiwe lapho okokusebenza kuphuma efekthri, futhi akufanele kushintshwe ngaphansi kwezimo ezijwayelekile.Lesi simo kufanele sidalwe izinkinga zokuklama.
6. Uma uwoyela wenjini weqa isikhathi sesevisi, uwoyela wenjini uzokonakala.
I-fluidity yamafutha enjini iba mpofu, futhi ukusebenza kokushintshana kokushisa kuncipha.Ngenxa yalokho, ukushisa okuvela ekhanda le-i-compressor yomoyaayikwazi ukususwa ngokuphelele, okuholela ekushiseni okuphezulu kwe-compressor yomoya.
7. Hlola ukuthi isipholile samafutha sisebenza ngokujwayelekile yini.
Ngamamodeli apholile ngamanzi, ungabheka umehluko wokushisa phakathi kwamapayipi okungena nokuphuma.Ezimweni ezijwayelekile, kufanele kube ngu-5-8 ° C.Uma ingaphansi kuka-5°C, ukukala noma ukuvinjelwa, okuzothinta ukusebenza kahle kokushintshisana kokushisa kwepholile futhi kubangele ukushabalaliswa kokushisa.Engalungile, ngalesi sikhathi, isishintshi sokushisa singasuswa futhi sihlanzwe.
8. Hlola ukuthi izinga lokushisa lokungena kwamanzi okupholisa liphezulu kakhulu yini, ukuthi ukucindezela kwamanzi nokugeleza kujwayelekile, futhi uhlole ukuthi izinga lokushisa le-ambient liphezulu kakhulu yini kumodeli yokupholisa umoya.
Izinga lokushisa lokungena kwamanzi okupholisa akufanele lidlule ku-35°C, futhi izinga lokugeleza akufanele libe ngaphansi kuka-90% wesilinganiso sokugeleza esishiwo lapho umfutho wamanzi uphakathi kuka-0.3 no-0.5MPA.
Izinga lokushisa le-ambient akufanele libe ngaphezu kuka-40°C.Uma lezi zidingo ezingenhla zingenakufinyelelwa, zingaxazululwa ngokufaka imibhoshongo yokupholisa, ukuthuthukisa umoya wangaphakathi wasendlini, nokwandisa indawo yegumbi lomshini.Ungaphinda uhlole ukuthi ingabe ifeni yokupholisa isebenza ngokujwayelekile, futhi uma kukhona ukwehluleka, kufanele ilungiswe noma ishintshwe.
