Ukuminyana kwe-brake fluid. Kala kanjani?

Ukuminyana kwe-DOT-4 brake fluid nokunye ukwakheka kwe-glycol

Ukuminyana koketshezi lwamabhuleki oluvame kakhulu namuhla, i-DOT-4, ngaphansi kwezimo ezijwayelekile, kuyahluka ukusuka ku-1,03 kuye ku-1.07 g/cm.³. Izimo ezijwayelekile zisho izinga lokushisa elingu-20 °C kanye nomfutho womkhathi ongu-765 mmHg.

Kungani ukuminyana koketshezi olufanayo ngokwezigaba kungahluka kuye ngohlobo olukhiqizwa ngaphansi kwalo? Impendulo ilula: indinganiso eyakhiwe uMnyango Wezokuthutha wase-US ayibeki imingcele eqinile mayelana nokwakheka kwamakhemikhali. Ngamagama ambalwa, leli zinga lihlinzekela: uhlobo lwesisekelo (ku-DOT-4 lawa ama-glycols), ukuba khona kwezithasiselo ze-antifoam, ama-corrosion inhibitors, kanye nezici zokusebenza. Ngaphezu kwalokho, ezicini zokusebenza, inani kuphela elicacisiwe, ngezansi lapho ipharamitha eyodwa noma enye ye-liquid akufanele iwe. Isibonelo, indawo yokubilisa entsha (ngaphandle kwamanzi) i-DOT-4 kufanele okungenani ibe ngu-230°C.

Izingxenye ezisele kanye nezilinganiso zazo zakha umehluko kubuningi obungabonwa oketshezini oluvela kubakhiqizi abahlukene.

Olunye uketshezi olusekelwe ku-glycol (DOT-3 kanye ne-DOT-5.1) lunokuminyana okufanayo njenge-DOT-4. Naphezu kokuhluka kwezithasiselo, ingxenye eyisisekelo, i-glycol, yenza cishe amaphesenti angu-98 yenani eliphelele. Ngakho-ke, awukho umehluko obalulekile wokuminyana phakathi kokwakheka okuhlukile kwe-glycol.

I-DOT-5 Silicone Fluid Density

Uketshezi lwe-DOT-5 luqukethe isisekelo se-silicone kanye nokwengezwa kwezithasiselo ngezinjongo ezihlukahlukene, ngokuvamile ngokufanayo nakwamanye ukwakheka kwamasistimu amabhuleki.

Ukuminyana koketshezi lwe-silicone olusetshenziselwa ukwakha izinhlanganisela zokusebenza zamasistimu amabhuleki kungaphansi kokwamanzi. Ilinganiselwa ku-0,96 g/cm³. Akunakwenzeka ukucacisa inani eliqondile, ngoba ama-silicone awanawo ubude obunqunyiwe bamayunithi we-siloxane. Isimo siyefana nama-polymers. Izixhumanisi ezingafika ku-3000 zingahlanganiswa ochungechungeni lwe-molecule ye-silicone. Nakuba eqinisweni ubude obujwayelekile be-molecule buncane kakhulu.

Izithasiselo zilula kancane isisekelo se-silicone. Ngakho-ke, ukuminyana kwe-DOT-5 brake fluid esekulungele ukusetshenziswa cishe ku-0,95 g/cm.³.

Ungahlola kanjani ukuminyana kwe-brake fluid?

Kunzima ukucabanga ukuthi ubani futhi ngaziphi izinjongo ngaphandle kwezimo zemboni ongadinga inqubo efana nokulinganisa ukuminyana kwe-brake fluid. Nokho, ikhona indlela yokulinganisa leli nani.

Ungakwazi ukukala ukwakheka kwe-glycol nge-hydrometer efanayo eklanyelwe ukukala ukuminyana kwe-antifreeze. Iqiniso liwukuthi i-ethylene glycol, into ehlobene nayo, isetshenziswa njengesisekelo sokusebenza ku-antifreeze. Kodwa-ke, iphutha lizoba likhulu uma usebenzisa le ndlela.

Indlela yesibili izodinga isikali esinembile (isilinganiso esincane sokuhlukanisa, esingcono) kanye nesitsha esilingana ncamashi namagremu ayi-100 (noma ilitha elingu-1). Inqubo yokulinganisa ngale ndlela iyancipha ibe yimisebenzi elandelayo.

1. Sikala izitsha ezomile nezihlanzekile esikalini.
2. Thela ku-100 amagremu we-brake fluid.
3. Sikala isitsha ngoketshezi.
4. Isusa isisindo se-tare esisindweni esiwumphumela.
5. Hlukanisa inani elitholwe ngamagremu ngo-100.
6. Sithola ukuminyana kwe-brake fluid ku-g / cm³.

Ngendlela yesibili, ngezinga elithile lephutha, ungakwazi ukukala ukuminyana kwanoma yiluphi uketshezi. Futhi ungakhohlwa ukuthi ukuminyana kuthinteka kakhulu izinga lokushisa lokubunjwa. Ngakho-ke, imiphumela yezilinganiso ezithathwe emazingeni okushisa ahlukene ingase ihluke.
