Ini ndinogona kusanganisa brake fluid kubva kune vakasiyana vagadziri?

Mhando dzemabhureki fluid uye maitiro avo

Parizvino, anonyanya kushandiswa mabhureki emvura akaiswa muyero zvichienderana neiyo US Dhipatimendi Rezvekutakurwa (Dhipatimendi Rezvekutakurwa). Pfupi yeDOT.

Zvinoenderana nerudzi urwu, inopfuura 95% yemotokari dzese nhasi dzinoshandisa imwe yeinotevera mvura:

• DOT-3;
• DOT-4 uye kugadziriswa kwayo;
• DOT-5;
• DOT-5.1.

Zvinwiwa zvemumba "Neva" (zvakafanana mukuumbwa neDOT-3, kazhinji zvakagadziridzwa nezvinowedzerwa zvinowedzera kutonhora), "Rosa" (inofananidzwa neDOT-4) nezvimwe zvakadaro zviri kuita zvishoma. Chikonzero cheizvi chaive shanduko yepasirese yevagadziri veRussia kuisa mazita zvinoenderana neAmerican standard.

Muchidimbu funga maitiro makuru uye chiyero chepamusoro mabhureki fluid.

1. DOT-3. Yechinyakare glycol fluid. Inonyanya kushandiswa mumotokari dzekunze makore anopfuura 15-20 uye muVAZ classics. Ane high hygroscopicity (kukwanisa kuunganidza mvura muhuwandu). Kuvira kwemvura yakachena kunosvika 205°C. Mushure mekuunganidzwa kwemvura inodarika 3,5% yehuwandu hwehuwandu hwemvura, nzvimbo yekuvira inodonha kusvika pa140 ° C. Inoita zvehasha kune mamwe mapurasitiki nemarubha.
2. DOT-4. Inoshandiswa mumotokari itsva. Hwaro ndeye polyglycol. Iyo ine yakanyanya kupikisa kutorwa kwemwando kubva kune zvakatipoteredza. Ndiko kuti, inotora nguva yakareba (paavhareji, kwemwedzi mitanhatu kana gore). Nekudaro, zvekuwedzera izvo zvinoderedza hygroscopicity uye chiyero chemakemikari aggression zvakakora ichi mvura. Pa -40 ° C, viscosity yakakwira zvishoma pane mamwe maDOT emvura. Kuvira kwemvura "yakaoma" i230°C. Hunyoro (kupfuura 3,5%) hunoderedza kuvira kusvika pa155°C.
3. DOT-5. silicone fluid. Haitore unyoro kubva kune zvakatipoteredza. Kumwe kuunganidzwa kwemwando kunogoneka nenzira ye condensate. Zvisinei, mvura haisanganisi nesilicone base uye precipitates (izvo zvinogonawo kukonzera zvakaipa). DOT-5 fluid haina kurerekera kwemakemikari. Inofashaira patembiricha isiri pasi pe260°C. Iine fluidity yakanaka pane yakaderera tembiricha.

1. 4. DOT-5.1. Yakagadziridzwa mota dzemitambo (kana mota nyowani) glycol kuumbwa. Mvura ine viscosity yakaderera zvikuru. Inongofashaira mushure mekupfuura 260 ° C point (pa3,5% humidity, iyo yekubikira inodonha kusvika 180 ° C). Iine kupikisa kwakanaka kune yakaderera tembiricha.

Mapiritsi maviri ekupedzisira anoshandiswa chete kana izvi zvakanyatsotemwa nemirairo yekushanda kwemotokari. Izvi zvinwiwa zvinogona kukanganisa mabhureki echikuru masisitimu, uko kuderera kwe viscosity kunogona kukonzera kuti sisitimu ishande uye kukonzera kubuda kwebrake caliper uye piston.

Miscibility yemabhureki fluid kubva kune vakasiyana vagadziri

Pakarepo pamusoro pechinhu chikuru: ese anoonekwa mabhureki emvura, kunze kweDOT-5, anogona kusanganiswa zvishoma kune mumwe nemumwe, zvisinei nemugadziri. Ikirasi ndiyo yakakosha, kwete mugadziri.

Variants vane mabhesi akasiyana haaenderane. Kana uchisanganisa silicone (DOT-5) uye glycol zvigadziko (zvimwe zvingasarudzwa), kupatsanurwa kuchaitika nemigumisiro yese inotevera. Nekuda kwehterogeneity, iyo mvura ichaita zvakasiyana kana ichipisa uye yatonhodzwa. Iko mukana wekuumbwa kwenzvimbo dzegasi plugs uchawedzera kakawanda.

Liquids DOT-3, DOT-4 uye DOT-5.1 inogona muchirevo kusanganiswa kwenguva pfupi pamwechete. Ingova nechokwadi chekutarisa kana mvura idzi dzakagadzirirwa kushanda neABS kana uine iyi system yakaiswa. Hapazovi nemhedzisiro yakaoma. Zvisinei, izvi zvinogona kuitwa chete mumamiriro ezvinhu akaoma uye kwenguva pfupi. Uye chete kana mvura yaidiwa isipo nokuda kwechikonzero chimwe kana chimwe. Asi kana motokari yako inoshandisa DOT-4 brake fluid kubva kufekitari, uye unogona kuitenga, haufaniri kuchengetedza uye kutora yakachipa DOT-3. Nekufamba kwenguva, izvi zvinotungamira kukurumidza kuparadzwa kweiyo system zvisimbiso kana matambudziko muABS system.

Zvakare, haufanire kutenga inodhura DOT-5.1 kana iyo system isina kugadzirirwa iyo. Hazvina musoro. Gasi kuumbwa uye kamwe kamwe kukundikana kwebhureki hazvizoitike kana sisitimu iri mumamiriro akanaka. Nekudaro, mutsauko ungangoita ka2 mune yakaderera-tembiricha viscosity inogona kudzvinyirira iyo brake system. Izvi zvinoitika sei? Pakupisa kusina kunaka, zvisimbiso zverabha zvinorasikirwa nekusimba. Pamotokari dzakagadzirirwa DOT-3 kana DOT-4, mvura yacho inokorawo zvakaenzana. Uye "brake" gobvu, kana ichiyerera nepakati pezvisimbiso zvakaomeswa zvakapihwa, ipapo mudiki. Kana iwe ukazadza yakaderera-viscosity DOT-5.1, saka munguva yechando unofanirwa kugadzirira kudonha kwayo. Kunyanya muchando chakanyanya.

Kugadziriswa kwakasiyana-siyana kweDOT-4 (DOT-4.5, DOT-4+, nezvimwewo) inogona kusanganiswa pamwe chete pasina kurambidzwa. Munyaya yakakosha yakadai sekuumbwa kwebhureki fluid, vese vanogadzira vanonyatso kuomerera kune zviyero. Kana yakanyorwa pagaba kuti iDOT-4, saka, kunze kwezviduku, kuumbwa kuchava nezvikamu zvakafanana, pasinei nemugadziri. Uye misiyano mukugadzirwa kwemakemikari haifanire kukanganisa kuenderana chero nzira.
