I-Antifreeze yesistimu ye-pneumatic. Defrost amabhuleki

Inkinga yezinhlelo ze-pneumatic eziqandisiwe

Umoya uqukethe umhwamuko wamanzi. Ngisho emazingeni okushisa amabi, kukhona amanzi emkhathini. Uhlelo lwe-pneumatic akulona uhlobo oluvaliwe, njenge-hydraulic. Okungukuthi, umoya uthathwa njalo emkhathini futhi, ngemva kokucindezeleka kunoma iyiphi isifunda, uxoshwa nge-valve yokuphuma kwegazi.

Kanye nomoya, amanzi ahlala engena ohlelweni. Uma ehlobo umswakama ucishe upheshulwe ngokuphelele emkhathini kanye nomoya ophumayo, khona-ke ebusika uyajiya futhi ube yiqhwa ngenxa yokuxhumana nezinto ezipholile kakhulu zesistimu ye-pneumatic.

Ngenxa yalesi sizathu, ama-valve, ulwelwesi kanye namakamelo e-piston avame ukuba yiqhwa, ngisho nasezimweni ezingavamile, imigqa ngokwayo incishiswe kakhulu noma iqhwa ngokuphelele. Futhi lokhu kuholela ekuhlulekeni okuyingxenye noma okuphelele kwesistimu ye-pneumatic.

Isebenza kanjani i-antifreeze yezinhlelo ze-pneumatic?

I-Antifreeze yesistimu ye-pneumatic iwuketshezi oluqukethe utshwala, umsebenzi oyinhloko okuwukuncibilikisa iqhwa nokuvimbela ukwakheka kweqhwa. Ngokungafani nokwakheka okufanayo, okufana ne-glass defrosters, i-antifreeze yezinhlelo ze-pneumatic ixuba kahle nomoya futhi, ngenxa yalokhu, ingena ezindaweni okunzima ukufinyelela kuzo.

Ngokuyisisekelo, lezi zinto eziwuketshezi zisetshenziselwa amabhuleki amaloli. Kodwa-ke, zingasetshenziswa nakwezinye izinhlelo zomoya ezicindezelwe. Utshwala buhlala ezindaweni ezineqhwa futhi bungene ekuphenduleni kwe-isothermal (ngokukhishwa kokushisa). Iqhwa liphenduka libe amanzi, okuthi kamuva lizinze phansi kwabemukeli noma likhishwe ngamavalvu opha.

Ama-antifreeze amaningi esimanje wezinhlelo ze-pneumatic angathathi hlangothi ngamakhemikhali maqondana nezingxenye zenjoloba, ipulasitiki ne-aluminium. Kodwa-ke, izethulo ziyaziwa lapho ukuhlukumeza noma ukusetshenziswa kabi kwaleli khemistri okuzenzakalelayo kubangele ukuphazamiseka ekusebenzeni kwe-pneumatics. Isibonelo, ukugcwaliswa okuvamile kwe-antifreeze yamabhuleki omoya kuyimbangela yokubanjwa okuyingxenye noma okuphelele kwama-piston asebenza kuma-pads ngenxa yokwakhiwa kongqimba lwetiyela ebusweni bamasilinda.

Emakethe yaseRussia, imikhiqizo emibili ethandwa kakhulu:

• Wabco Wabcothyl - ukwakheka kwangempela okuvela kumkhiqizi wesistimu yamabhuleki nezinye izixazululo zobuchwepheshe ezinedumela lomhlaba wonke;
• I-Liqui Moly antifreeze yamabhuleki omoya - i-antifreeze evela kumkhiqizi owaziwayo waseJalimane wamakhemikhali ezimoto.

Abashayeli bezimoto ngokuvamile bakhuluma kahle ngokulinganayo ngalezi zinhlanganisela ezimbili. Kodwa-ke, abaningi bagcizelela ukuthi ekusebenzeni okujwayelekile kwe-antifreeze, kuyadingeka ukuyigcwalisa kuphela uma kunesidingo, futhi ngemva kokugijima okuhleliwe, kubalulekile ukukhipha i-condensate.

Ukuthela kuphi?

Kuyadingeka ukugcwalisa i-antifreeze kumasistimu we-pneumatic, kuye ngokuthi ipulaki yeqhwa yakhiwe kuphi. Futhi kulezo zimo, uma kukhona ukuphazamiseka ekusebenzeni kwamabhuleki omoya noma amanye amadivaysi anikezwa umoya ocindezelwe.

Uma isomisi sisebenza ngokujwayelekile, ukugcwaliswa kungenziwa ngqo emgodini wokufaka isihlungi. Kwezinye izimo, kuyinkinga ukukhulula isihlungi ebusika. Khona-ke i-antifreeze ingathululelwa endaweni yokuphuma ngaphansi kwendlu yokuhlunga, lapho ipayipi legatsha lingena khona ohlelweni.

Uma isomisi sifriziwe, kungcono ukuthulula i-antifreeze ku-tube yokungena noma emgodini ngaphansi kwesihlungi. Kuyajwayela futhi ukugcwalisa uhlelo ngembobo yokungenisa ku-compressor.

Uma kwenzeka ipulaki yakheka ohlelweni lwe-pneumatic ye-trailer, kuyadingeka ukugcwalisa i-antifreeze kuphela emgqeni wengcindezi ophakathi, lapho ukucindezela komoya osebenzayo kudlula khona. Ukugcwalisa kabusha i-antifreeze emgqeni wokulawula kungase kungabi namphumela, ngoba i-antifreeze izohlala kuwo futhi ngeke idlule kulo lonke uhlelo lwe-pneumatic.

Ngemuva kokugijima kwe-200 kuya ku-1000 km, kuyadingeka ukukhipha i-condensate encibilikile ohlelweni. Qiniseka ukuthi uthulula zonke izamukeli, ngaphandle kwalokho umswakama uzohlangana nomoya lapho izinga lokushisa lishintsha futhi uqale futhi ukujikeleza emigqeni, ujiya ohlelweni lwama-valve noma ama-actuator.

Akunconywa ukuthululela i-antifreeze ezinhlelweni ze-pneumatic lapho kungekho zinkinga ngeqhwa. I-antifreeze ye-air brake kufanele isetshenziswe kuphela uma ukuqandisa sekuvele kwenzeke. Ukusetshenziswa kokuvimbela akuwenzi umqondo futhi kungalimaza ngisho nezingxenye zenjoloba ne-aluminium.
