Brake fluid tester. Kuyang'ana makina ofunika kwambiri agalimoto
Zamkatimu
Chifukwa chiyani ma brake fluid testers akufunika?
Ma brake fluid ndi oposa 95% glycols kapena polyglycols. Ma alcohols osavutawa ali ndi machitidwe abwino a machitidwe, omwe amawalola kuti agwiritsidwe ntchito m'mabuleki amakono. Glycol brake fluids amatumiza kupanikizika kwa mtunda wautali popanda kupotoza, ali ndi mafuta ambiri, ndipo sagonjetsedwa ndi kutentha kwakukulu ndi kutsika.
Komabe, ma glycols ali ndi mbali imodzi yomwe siili yofunikira, komanso yowopsa. Mowa uwu ndi hygroscopic. Ndiko kuti, amatha kudziunjikira chinyezi kuchokera ku chilengedwe. Ndipo kukhalapo kwa madzi mu voliyumu ya brake fluid kumabweretsa kutsika kwambiri pakuwira kwake. "Mabuleki" omwe adaphika m'misewu ikuluikulu adzayimitsa dongosolo lonse nthawi yomweyo. Mabuleki adzangolephera. Mwachitsanzo, kuwoneka kwa madzi 3,5% okha mumadzi a DOT-4 kumachepetsa kuwira kwake kuchoka pa 230 °C mpaka 155 °C.
Madzi amawunjikana mu brake fluid pang'onopang'ono. Kuthamanga kwa njirayi kumadalira zinthu zambiri: kutentha kozungulira, chinyezi cha mpweya, mphamvu ya galimoto, mapangidwe a brake system, etc. Choncho, n'zosatheka kudziwiratu ngati chinyezi chochuluka chachuluka mumadzimadzi pokhapokha nthawi yogwira ntchito.
Pali tsiku lotha ntchito ya brake fluid, koma izi siziyenera kusokonezedwa ndi moyo wautumiki. Izi ndi zinthu zosiyana. Tsiku lotha ntchito limasonyeza nthawi ya alumali ya mankhwala mu chidebe chotsekedwa.
Chifukwa chake, ma analyzer apadera apangidwa kuti awonetsetse kuti ma brake fluid ali ndi madzi mmenemo.
Momwe ntchito
Choyesa chilichonse cha brake fluid, mosasamala kanthu za kapangidwe ka mtundu wina, chimakhala ndi batire, maelekitirodi awiri ndi dera lamagetsi lomwe lili ndi algorithm yowunika zowerengera. Nthawi zina ma electrode oyesa amaphatikizidwa mu probe imodzi. Nthawi zina, amagawidwa m'zigawo ziwiri zosiyana zomwe zimakhazikitsidwa pamlanduwo. Koma pali mfundo yofunika kwambiri apa: mtunda wapakati pa ma electrode mu tester iliyonse umakhala wosasinthika.
Poyambirira, madzimadzi a brake owuma opanda chinyezi (kapena ndi kuchuluka kwake) amakhala ndi kukana kwamagetsi. Pamene madzi akuwunjikana, kukana kwa madzimadzi kumachepa. Ndi mtengo uwu womwe tester ya brake fluid imayeza. Panopa amagwiritsidwa ntchito pa imodzi mwa maelekitirodi, omwe amadutsa mumadzimadzi ndikulowa mu electrode ina. Ndipo kukana kwa madzi wothira kumatsimikizira kutsika kwamagetsi mumtundu woterewu wamagetsi. Kutsika kwamagetsi kumeneku kumagwira "ubongo" wa tester ndikutanthauzira molingana ndi maziko omwe amakumbukira. Kukaniza kwa ndimeyi yamagetsi yamagetsi kumasinthidwa kukhala kuchuluka kwa chinyezi mumadzimadzi.
Ngati musintha mtunda pakati pa ma electrode, ndiye kuti kukana kwamadzimadzi kudzasintha: kumawonjezeka pamene ma electrode amachotsedwa ndipo mosiyana. Padzakhala kupotozedwa kwa kuwerenga. Chifukwa chake, oyesa omwe ali ndi maelekitirodi owonongeka kapena opunduka angapereke chidziwitso cholakwika.
Kodi ntchito?
Kugwiritsa ntchito brake fluid quality tester nthawi zambiri kumabwera pamachitidwe awiri osavuta.
- Kuyatsa chipangizo ndikudikirira diode yokonzeka kuyatsa (nthawi zambiri kuwala kwa LED kobiriwira, komwe kumawonetsa kusakhalapo kwa chinyezi mumadzimadzi).
- Kutsitsa maelekitirodi a chipangizocho mu thanki mpaka chizindikiro chimodzi cha mkhalidwe wamadzi chiyatse. Pankhaniyi, ndikofunika kutsitsa chipangizocho kapena kufufuza kwakutali mu thanki mosamalitsa. Nthawi zambiri, woyesa amawunika momwe madziwo alili mumasekondi 1-2.
Pambuyo pa miyeso, ma electrode ayenera kupukutidwa ndi chiguduli.
Chofunikira ndi kukhalapo kwa 3,5% chinyezi mumtundu wa brake fluid. Izi zimawonetsedwa ndi diode yofiyira kapena nyali yoyatsa yoyaka pagawo lofiyira la sikelo yowunikira chidacho. Ngati pali 3,5% madzi ndi voliyumu, madzimadzi ayenera kusinthidwa mwamsanga.
Mtengo ndi ndemanga
Pakadali pano, pafupifupi ma brake fluid testers omwe amagulitsidwa m'masitolo aku Russia ali ndi "chizindikiro". Kunja, amawoneka ngati cholembera chokhazikika. Mtengo wawo umachokera ku 200 mpaka 500 rubles, malingana ndi chitsanzo ndi malire a wogulitsa.
Pakatikati mwa woyesa wotereyo ndi batri ya AAA. Kutsogolo, pansi pa kapu, pali maelekitirodi awiri achitsulo, omwe ayenera kumizidwa mumadzimadzi onyema. Pamwamba pake pali batani lamphamvu. Mtundu uwu wa tester ndi wabwino kugwiritsa ntchito payekha.
Ma brake fluid tester apamwamba kwambiri sapezeka kawirikawiri. Nthawi zambiri amagwiritsidwa ntchito m'malo operekera chithandizo ndi magalimoto. Mwachitsanzo, zida zotsatirazi zitha kupezekabe pakugulitsidwa:
- Brake Fluid Tester ADD7704 - mtengo m'masitolo aku Russia ndi pafupifupi ma ruble 6 zikwi;
- Brake Fluid Tester ADD7703 - amapezeka nthawi zambiri, mutha kugula ma ruble 3-3,5 zikwi.
- Brake Fluid Tester WH-509 - imawononga pafupifupi ma ruble 12, sichigulitsidwa ku Russian Federation.
Akatswiri oyesa ma brake fluid ali ndi makonda osinthika komanso kuchuluka kwa kuyeza kolondola. Chimodzi mwazosankha ndikuwunika mwatsopano brake fluid ngati cholozera ndikuyesa chipangizocho molingana ndi zomwe adalandira.
Kuti muwongolere mkhalidwe wamadzi agalimoto yanu, choyesa chotsika mtengo cha pensulo ndichokwanira. Oyendetsa galimoto ndi akatswiri oyendetsa magalimoto amanena kuti umboni wake ndi wokwanira kuti awunikenso mokwanira. Ndipo ndemanga zamadalaivala pamaneti pazida izi nthawi zambiri zimakhala zabwino. Chipangizocho ndi chosavuta komanso chosavuta kugwiritsa ntchito. Njira yowunikira "brake" imatenga mphindi 1-2 ndi ntchito zonse zogwirizana. Ndipo kulakwitsa kwa zizindikiro sikudutsa 10%.
