Density yeDOT-4 brake fluid uye mamwe magadzirirwo eglycol
Kuwanda kweiyo yakajairika brake fluid nhasi, DOT-4, pasi pemamiriro akajairwa, inosiyana kubva pa1,03 kusvika 1.07 g/cm.3. Mamiriro ezvinhu akajairika anoreva tembiricha ye20 °C uye mhepo yemhepo ye765 mmHg.
Sei density yemvura imwe chete zvichienderana nechikamu ichisiyana zvichienderana nerudzi painogadzirwa? Mhinduro iri nyore: chiyero chakagadziridzwa neUS Dhipatimendi Rezvekutakurwa hariisi miganhu yakasimba maererano nemakemikari. Mumashoko mashomanana, chiyero ichi chinopa: rudzi rwechigadziko (cheDOT-4 idzi glycols), kuvapo kwe antifoam additives, corrosion inhibitors, pamwe chete nemaitiro ekushanda. Uyezve, mune maitiro ekuita, kukosha chete kunotsanangurwa, pazasi iyo imwe kana imwe yemvura parameter haifanirwe kudonha. Semuenzaniso, nzvimbo yekubikira yakachena (isina mvura) DOT-4 inofanira kunge iri 230 ° C.
Izvo zvakasara zvikamu uye zviyero zvazvo zvinoumba mutsauko mukuwanda unogona kucherechedzwa mune zvinwiwa kubva kune vakasiyana vagadziri.
Mamwe glycol based fluids (DOT-3 uye DOT-5.1) ane density yakafanana neDOT-4. Pasinei nekusiyana kwezvinowedzera, chikamu chepasi, glycol, chinoumba inenge 98% yehuwandu. Naizvozvo, hapana misiyano yakakosha mukuwanda pakati peakasiyana glycol formulations.
DOT-5 Silicone Fluid Density
DOT-5 fluid ine chigadziko chesilicone pamwe nekuwedzera kwezvinowedzera kune zvakasiyana siyana, zvakangofanana mune mamwe magadzirirwo emabhureki masisitimu.
Kuwanda kwemafuta esilicone anoshandiswa kugadzira makomisheni ekushanda emabhureki masisitimu ishoma pane yemvura. Inenge iri 0,96 g/cm3. Izvo hazvigoneke kuona kukosha chaiko, nekuti silicones haina kunyatsotsanangurwa kureba kweiyo siloxane mayuniti. Mamiriro acho akafanana nemapolymers. Anosvika zviuru mazana matatu zvinongedzo zvinogona kuunganidzwa muketani yesilicone molecule. Kunyangwe hazvo paavhareji urefu hwemorekuru hwakaderera.
Zvinowedzera zvinorerutsa iyo silicone base. Naizvozvo, kuwanda kweiyo yakagadzirira kushandisa DOT-5 brake fluid inosvika 0,95 g/cm.3.
Nzira yekutarisa sei kuwanda kweiyo brake fluid?
Zvakaoma kufungidzira kuti ndiani uye nezvikonzero zvipi kunze kwemamiriro eindasitiri angangoda maitiro akadai sekuyera kuwanda kweiyo brake fluid. Zvisinei, pane nzira yokuyera nayo kukosha uku.
Iwe unogona kuyera kuumbwa kweglycol neiyo hydrometer yakafanana yakagadzirirwa kuyera density yeantifreeze. Ichokwadi ndechokuti ethylene glycol, chinhu chakabatana, chinoshandiswa sechinhu chinoshanda mu antifreeze. Nekudaro, iko kukanganisa kuchave kwakakosha kana uchishandisa nzira iyi.
Nzira yechipiri inoda zviyero zvakarurama (idiki chiyero chekuparadzanisa, chiri nani) uye chigadziko chinokwana 100 gramu (kana 1 litre). Nzira yekuyera nenzira iyi inoderedzwa kusvika kumabasa anotevera.
- Tinoyera midziyo yakaoma, yakachena pazvikero.
- Dururira 100 gramu yebrake fluid.
- Tinoyera mudziyo nemvura.
- Inobvisa huremu hwetare kubva pahuremu hwabuda.
- Kamura kukosha kunowanikwa mumagiramu ne100.
- Isu tinowana kuwanda kweiyo brake fluid mu g / cm3.
Nenzira yechipiri, neimwe dhigirii yekukanganisa, unogona kuyera density yechero mvura. Uye usakanganwa kuti density inonyanya kukanganiswa nekupisa kwekuumbwa. Nokudaro, migumisiro yezviyero zvinotorwa pamatembiricha akasiyana zvinogona kusiyana.
