Density ye antifreeze
Anenge ese maantifreezes emazuva ano anogadzirwa pahwaro hwedoro (imwe yekusiyana kweglycol) uye yakasvibiswa mvura. Chiyero che glycol kumvura chinotarisa kupikisa kuderera kwekushisa.
Pane gangaidzo pano rakakosha kunzwisisa. Kune ethylene glycol antifreezes, mutemo haushande: iyo yakakwira iyo yakawanda yeglycol, iyo yakawanda yechando musanganiswa inogona kushivirira. Pure ethylene glycol ine kutonhora kwechando ingori -13°C. Uye iyo yakakwirira yechando chikumbaridzo cheinotonhorera inowanikwa nekusanganiswa nemvura.
Kusvikira kuhuwandu hwe glycol mukuumbwa kweanenge 67%, kunatsiridza kwepasi-kupisa zvinhu kunoitika. Nereshiyo iyi, kuramba kwakanyanya kuchando kunowanikwa. Kunotevera kunouya zvishoma nezvishoma shanduko yekudira poindi yakananga kune yakanaka tembiricha. Kune matafura anodonongodza zvimiro zveakasiyana mazinga e glycols nemvura.
Kuwanda kweantifreeze hakubvi pane ruvara rwayo. Pamwe chete nenzvimbo yechando. Izvo hazvina basa kana isu tichidzidza density yegirinhi antifreeze, yero kana tsvuku, zvinokonzeresa kukosha hazvizoenderane nemuvara. Iyo ruvara inosarudza kuumbwa kwezvinowedzera uye kushanda kweantifreeze yemotokari dzakasiyana. Zvisinei, pari zvino pane kuvhiringika muhurongwa uhu. Nokudaro, hazvibviri kuisa pfungwa pavara chete.
Parizvino, anonyanya kufarirwa antifreezes ndeaya: G11, G12, G12 +, G12 ++ uye G13. Kune ese anotonhorera, kuwanda kunosiyana zvichienderana nenzvimbo yekudira (glycol concentration). Kune akawanda emazuva ano anotonhorera, nhamba iyi yakatenderedza 1,070-1,072 g / cm3, iyo inenge inoenderana nenzvimbo yechando ye -40 °C. Kureva, antifreeze inorema kupfuura mvura.
Mudziyo wekuyera kuwanda kweantifreeze
Kuwanda kweantifreeze kunogona kuyerwa neyakajairwa hydrometer. Ichi ndicho chigadziri chakakodzera. Iwe unongoda kuwana vhezheni ye hydrometer, yakagadzirirwa kuyera density ye glycol musanganiswa.
Iyo hydrometer ine zvikamu zviviri zvikuru:
- flasks (ine rubber tip kune rumwe rutivi uye peya kune imwe) yekutora antifreeze mukati;
- kuyangarara nechiyero.
Mukati meiyo hydrometer, iyo yakanyatso kugadzirirwa kuyera density yeantifreeze, pane kazhinji kacho inopinza. Kwete chete density inotaridzwa pairi, asiwo iyo yekuisa glycol inoenderana nayo. Mamwe, mamwe mavhezheni akagadziridzwa, anobva angopa ruzivo rwekutonhora kweiyo antifreeze pasi pekudzidza. Izvi zvinobvisa kukosha kwekuzvimiririra kutsvaga kukosha mutafura uye kunoita kuti maitiro acho akurumidze uye nyore.
Nzira yekuyera sei density ye antifreeze kumba?
Maitiro ekuyera ne hydrometer ari nyore. Izvo zvinodikanwa kudhirowa yakakwana antifreeze muflask kubva mugaba kana zvakananga kubva kune inotonhorera system kuti iyangamire iyo inoyangarara. Zvadaro, tarisa payangarara. Chiyero chainonyura chicharatidza kuwanda. Mushure mekuyera, zvakakwana kuenzanisa kuwanda nehuwandu hwe ethylene glycol, inoenderana nehupamhi iyi, kana nekudurura.
Pane imwe nzira yekuyera density kumba. Izvi zvinoda zviyero zvakaringana (iwe unogona kushandisa zviyero zvekicheni) uye mudziyo une vhoriyamu chaiyo 1 litre. Iyo density kuyerwa maitiro mune iyi kesi ichave nematanho anotevera:
- tinoyera mudziyo usina chinhu uye tinonyora chigumisiro;
- dururira 1 litre yeantifreeze mumudziyo uyu uye uite imwezve kuyera;
- bvisa huremu hwetare kubva pahuremu hwakakura uye uwane net net ye 1 litre ye antifreeze;
Izvi zvichava density ye antifreeze. Iyo nzira inogona kutaura chokwadi chete kana zviyero zvakavimbiswa kuratidza huremu chaihwo, uye mudziyo unobata 1 litre chaiyo yemvura.
