Kungani i-compressor idinga ibhande lokushisa le-crankcase?

Phansi kwephampu yokushisa yomthombo womoya kanye ne-air conditioning yangaphandle yeyunithi compressor, sizomisaibhande lokushisa le-compressor(eyaziwa nangokuthi i-I-heater ye-crankcase). Uyazi ukuthi i-heater ye-crankcase yenzani? Ake ngichaze:

Isici sokushisa se-I-compressor crankcase ibhande lokushisaihlelwe ngocingo lwe-nickel-chromium alloy resistance, ukushisa ngokushesha, izinga lokushisa elifanayo, ungqimba lokufakelwa lwenziwe ngokumelana nokushisa okuphakeme nokuphansi, i-anti-corrosion, ukushisa okuphezulu, ukumelana nokuguga kwe-silicone irabha kanye nendwangu ye-fiber engeyona yamakhemikhali, irabha ye-foam engenisiwe nezinye izinto zokwakha, ezakhiwe nge-lining, ungqimba oluphakathi olushisayo olushisayo, ungqimba olungaphandle oluvikelayo, izingqimba ezintathu zokuzivikela, ukuqina kokushisa okuthembekile, ukumelana nokushisa okuthembekile, ukuguquguquka okuhle kokushisa. into, ukusebenza kahle okuphezulu kokushisa, kulula ukuyisebenzisa, kungalimaza ngokuqondile ebusweni bengxenye evuthayo.

Umsebenzi oyinhloko weibhande lokushisa eliphansi le-compressorukuvimbela ukucindezela koketshezi ngesikhathi sokuqala nokusebenza kwe-compressor. Ekusebenzeni kwesizini kwe-air conditioner, noma ngemuva kokuthi i-air conditioning ephakathi isanda kufakwa, ngaphambi kwe-boot yokuqala (noma ukuthunywa), kuyadingeka ukushisa iyunithi kusengaphambili (ngokuvamile amahora angaphezu kuka-6). Ngemuva kokunikezwa amandla kusengaphambili, i-I-compressor crankcase heaterukunikezwa kwamandla kagesi, isiqandisi esiwuketshezi ku-compressor singahwamuka kusenesikhathi ukuze kuqinisekiswe impilo yesevisi ye-compressor. (Ithiphu, lapho i-air conditioner ingasetshenzisiwe isikhathi eside, kuyadingeka ukucisha amayunithi angaphakathi nangaphandle, ngoba indawo yokushisa kagesi izokhiqiza inani elithile lokulahlekelwa kwamandla.)

I-logic yokulawula ye-ibhande le-heater ye-crankcaseilawulwa ngokuyinhloko ngokusho kwenzwa yokushisa ngaphansi kwe-compressor, futhi isimo se-air conditioning esimaphakathi sizoba nzima kakhulu, okubandakanya inkinga yokushisa okuphezulu okuhambisana nenani lokuthola inzwa yokucindezela okuphansi. Umsebenzi we-ibhande lokushisa le-compressorukwenza izinga lokushisa le-compressor lubricating oil libe phezulu kunokushisa kwe-saturation, okungukuthi, ukulawula izinga lokushisa likawoyela we-compressor lingaphezu kuka-0, ukuvimbela uwoyela wokugcoba ukuthi ungahlanjululwa yisiqandisi kanye nokuqinisekisa ukuthi uwoyela wokugcoba awuncibiliki isiqandisi se-liquid esiningi, ngaphandle kwalokho uzoqala ngoketshezi, wehlise i-viscosity ye-lubrication kawoyela we-compressor. anele. Endabeni yokushisa okuphansi, ukufuduka kwesiqandisi kubhekisela ekufudukeni okuguquguqukayo kwesiqandisi ohlelweni oluvaliwe lapho i-compressor ingasebenzi isikhathi eside, ukuze kube khona isenzakalo sokuqoqwa kwefriji ye-liquid ku-compressor. Uma uqala futhi usebenza, iyunithi yangaphandle kanye ne-gas-liquid separator iyahwamuka futhi ibilise kakhulu, ngoba izinga lokushisa lomshini liphansi, i-condensate ifakiwe, futhi amafutha okucindezela akhishwa emshinini.

Ukuqonda okulula ukuvimbela i-compressor ukuthi ingashayi kanye nokushoda kukawoyela lapho i-standby yezinga lokushisa eliphansi iqala futhi isebenza isikhathi eside ukuze kuqinisekiswe ukwethembeka kwayo.
