DOT yakadzvanya fluid fluid kupatsanura uye tsananguro

Brake fluid chinhu chakakosha chinozadza mabhureki emota uye inoita basa rakakosha mukushanda kwayo. Inochinjisa simba kubva pakutsikirira bhureki remabhureki kuburikidza neiyo hydraulic dhiraivha kuenda kune mabhureki mabhureki, nekuda kwekuti mota yakaputsika ndokumiswa. Kuchengetedza huwandu hunodiwa uye hunhu hwakakodzera hwebhureki fluid mune ino system ndiyo kiyi yekutyaira kwakachengeteka.

Chinangwa uye zvinodiwa kuti akamedura mvura

Chinangwa chikuru chebhureki fluid ndiko kuendesa simba kubva kubrinder cylinder kuenda kumabhureki emavhiri.

Kugadzikana kwekubhururuka kwemotokari kwakananganawo zvakananga nehunhu hweiyo brake fluid. Inofanira kuzadzisa zvese zvakakosha kwavari. Uyezve, iwe unofanirwa kutarisisa kune iye anogadzira iyo fluid.

Zvidimbu zvekuda mabhureki emvura:

1. Yakakwira kufashaira poindi. Iyo yakakwira iyo, kushoma mukana wekuumbwa kwemafuro emhepo mukati memvura uye, semhedzisiro, kuderera kwesimba rinotapurirana.
2. Nzvimbo inotonhora inotonhora.
3. Iyo yemvura inofanirwa kuchengetedza kudzikama kwezvinhu zvayo muhupenyu hwayo hwese hwebasa.
4. Low hygroscopicity (kune glycol zvigadziko). Kuvapo kwehunyoro mukati memvura kunogona kutungamira mukuora kweakavhuna system zvikamu. Naizvozvo, iyo mvura inofanirwa kunge iine chivakwa chakadai senge mashoma hygroscopicity. Mune mamwe mazwi, inofanira kutora mwando zvishoma sezvinobvira. Kune izvi, iyo corrosion inhibitors yakawedzerwa pairi, ichidzivirira mamiriro ehurongwa kubva kune yekupedzisira. Izvi zvinoshanda kune glycol-based fluids.
5. Lubricating zvivakwa: kudzora kupfeka kwemabhureki system zvikamu.
6. Hapana zvinokuvadza pamitezo yerabha (O-zvindori, macuffs, nezvimwewo).

Akamedura Urume sezvamunoita

Akaputsa Urume ine hwaro uye zvakasiyana tsvina (yokuvirisa). Iyo base inogadzira inosvika 98% yechimiro chemvura uye inomiririrwa ne polyglycol kana silicone. Muzviitiko zvakawanda, polyglycol inoshandiswa.

MaEthers anoita sezvinhu zvinowedzera, izvo zvinodzivirira kusanganiswa kwemvura neoksijeni yemhepo uye nekupisa kwakasimba. Zvakare, zvinowedzera zvinodzivirira zvikamu kubva kune ngura uye zvine lubricating zvivakwa. Kubatanidzwa kwezvikamu zvebrake fluid kunoona zvivakwa zvayo.

Iwe unogona chete kusanganisa zvinwiwa kana zviine hwaro hwakaenzana. Zvikasadaro, hunhu hwekuita hunhu hwechinhu hunodzikira, izvo zvinogona kutungamira mukukuvadza kwezvinhu zvebrake system.

Kupatsanura kwemabhureki emvura

Mabhureki emvura anoiswa mumhando dzakasiyana. Kurongwa uku kunoenderana nenzvimbo yekubikira yemvura uye neinematic viscosity maererano neiyo DOT (Dhipatimendi reZvekufambisa) zviyero. Aya matanho anotorwa neDhipatimendi Rekufambisa reUS.

Kinematic viscosity inokonzeresa kugona kwemvura kutenderera mumutsetse wekupwanya pane kwakanyanya kushanda tembiricha (-40 kusvika +100 degrees Celsius).

Iyo yekubikira poindi ine basa rekudzivirira kuumbwa kwemhepo inovhara iyo inoumba pane yakanyanya kupisa. Iyo yekupedzisira inogona kutungamira kuchokwadi chekuti bhureki rekumedura harite panguva yakakodzera. Iyo tembiricha chiratidzo inowanzo funga nezve iyo inovirisa nzvimbo ye "yakaoma" (isina tsvina yemvura) uye "yakanyoroveswa" mvura. Chiyero chemvura mu "humidified" mvura inosvika ku4%.

Kune makirasi mana emabhureki emvura: DOT 3, DOT 4, DOT 5, DOT 5.1.

1. DOT 3 inogona kumira tembiricha: 205 degrees - ye "yakaoma" mvura uye 140 degrees - ye "humid" imwe. Mvura idzi dzinoshandiswa pasi pechinyakare mashandiro ezvinhu mumotokari dzine dhiramu kana disc mabhureki.
2. DOT 4 inoshandiswa pamotokari dzine disc mabhureki mumigwagwa yemumaguta (kukurumidza-kudzora modhi). Nzvimbo yekubikira pano ichave madigiri makumi maviri nemaviri - ye "yakaoma" mvura uye madigiri gumi nemashanu - ye "nyoro" imwe. Urume uhu hunonyanya kuwanikwa mumotokari dzamazuvano.
3. DOT 5 isilicone yakavakirwa uye haienderane nezvimwe zvinwiwa. Nzvimbo yekubikira yemvura yakadaro ichave iri 260 uye 180 madhigirii, zvichiteerana. Urume uhwu haukonzere kupenda uye hautore mvura. Semutemo, hazviite kune zvigadzirwa zvemotokari. Iyo inowanzo shandiswa mune yakakosha mota inoshanda mune yakanyanya tembiricha yeiyo braking system.
4. DOT 5.1 inoshandiswa mumitambo yemitambo uye ine imwechete yekubikira poindi seDOT 5.

Iyo kinematic viscosity yemarudzi ese emvura pane tembiricha ye100 madigiri haina kupfuura 1,5 sq. mm / s., Uye pa -40 - zvinosiyana. Kune yekutanga mhando, iyi kukosha ichave 1500 mm ^ 2 / s, yechipiri - 1800 mm ^ 2 / s, kwekupedzisira - 900 mm ^ 2 / s.

Kana zviri zvakanakira nekukanganisa kwerudzi rwemhando yemvura, zvinotevera zvinogona kusiyaniswa:

• yakadzika kirasi, yakaderera mutengo;
• iyo yakadzika kirasi, iyo yakakwira iyo hygroscopicity;
• zvinokanganisa zvikamu zverabha: DOT 3 inokanganisa zvikamu zverabha uye DOT 1 zvinwiwa zvatoenderana zvizere nazvo.

Paunenge uchisarudza brake fluid, muridzi wemota anofanira kuteedzera rairo yemugadziri.

Features kushanda uye kutsiva akamedura Urume

Kakawanda sei iyo brake fluid inoshandurwa? Hupenyu hwebasa remvura inoiswa neiye automaker. Iyo brake fluid inofanirwa kuchinjwa nenguva. Iwe haufanire kumirira kusvikira mamiriro ake ave padhuze nekukosha.

Iwe unogona kuona nemeso mamiriro echinhu nekutaridzika kwayo. Iyo brake fluid inofanirwa kunge yakafanana, yakajeka uye isina sediment. Uye zvakare, mumasevhisi emotokari, nzvimbo yekubikira yemvura inoongororwa nezviratidzo zvakakosha.

Iyo inodiwa nguva yekuongorora mamiriro emvura kamwe pagore. Polyglycolic fluid inoda kuchinjwa makore maviri kusvika matatu ega ega, uye silicone fluid - makore gumi kusvika gumi nemashanu. Iyo yekupedzisira inosiyaniswa nekugara kwayo uye makemikari akaumbwa, asingagone kune zvekunze zvinhu.

mhedziso

Zvimwe zvinodikanwa zvinoiswa pahunhu uye kuumbwa kweiyo brake fluid, nekuti iko kuvimbika kweiyo brake system kunoenderana nazvo. Asi kunyangwe yepamusoro-soro mabhureki emvura anotanga kudzikira nekufamba kwenguva. Naizvozvo, zvinodikanwa kuti uongorore uye uchichinje munguva.
