Kutsanangura Basa reChigaro cheMabhureki muPneumatic Systems
Kamuri remabhureki rerori rinoshandura simba remhepo yakamanikidzwa kuita simba rekushandisa mabhureki. Mugadziriro yeS-cam yakajairika, kumanikidzwa kwemhepo kunofambisa diaphragm, iyo inosunda tsvimbo kuti itenderedze slack adjuster. Kutonhora kwakanyanya kunokanganisa kushandurwa kwesimba iri nekuwedzera kuputsika kwezvikamu zverabha uye kushandura viscosity yemafuta emukati. Kuchengetedza kushanda kwakanaka kwekamuri remabhureki kunoita kuti simba rekusunga rirambe rakafanana pasinei nekunetseka kwekunze kwezvakatipoteredza.
Kuchinja kweSub-Zero Kunoita Sei Kuoma kweDiaphragm
Diaphragm yerabha ndiyo inonyanya kubatwa nekupisa mukati mekamuri remabhureki. Kana tembiricha yadzikira pasi pe -30°C, mishonga yerabha yakagadzirwa inosvika patembiricha yayo yekuchinja kwegirazi, yova yakaoma uye inowanzotsemuka. Kurasikirwa nekuchinjika uku kunotungamira ku "kubuda kwemhepo zvishoma nezvishoma," uko mhepo inobuda panguva yekushandiswa, zvichideredza kumanikidzwa kwese kunoitwa pashangu dzebhureki. Kutsvaga zvinhu zvemhando yepamusoro kubva kumusika wezvishandiso zvemabhureki anovimbwa nawo kwakakosha kuti uve nechokwadi chekushandisa diaphragm dzinodzivirira kupisa kwakaderera dzeEPDM kana silicone.
Kuneta Kwechirimo Uye Kunonoka Kusunungurwa Munguva Yechando
Makamuri emabhureki ekupaka anoshandisa chitubu chemagetsi chinorema kuti mota isamire.

Uyezve, hunyoro hwakaomeswa nechando huri mukati memba hunogona kukonzera kuti chitubu "chirembedzeke," zvichidzivirira mabhureki kuti asaburitse zvizere mushure mekunge mutyairi abvisa vharuvhu yekupaka. Kudhonza uku kunowedzera kupisa nekupfekwa kwedhiramu rebhureki, zvichikonzera kutadza kushanda kwechikamu chose chevhiri.
Zvinokanganisa Michina: Unyoro uye Kuumbwa kweAizi
Hunyoro ndiyo muvengi mukuru wemabhureki emhepo munguva yechando. Kunyangwe paine mudziyo wekuomesa mhepo unoshanda, kuchinja-chinja kwekushisa nekukurumidza kunokonzera kuungana mukati memitsetse yemabhureki nemakamuri. Mvura iyi inogona kuoma nechando kuita makristaro echando anovhara madhoo madiki ari mukamuri kana kuvharira mashandiro epushrod. Sekureva kwazvinoitwa neMasisitimu eMotokari dzeMabhizinesi eBendix, kubvisa mvura mumatangi emhepo nguva dzose uye kushandisa maair dryers ane hunyanzvi hwepamusoro ndiyo nzira yekutanga yekudzivirira kutadza kwemabhureki nekuda kwechando.
Kukundikana kwemafuta uye Kuwedzera kwekukweshana
Zvikamu zvemukati mekamuri remabhureki zvakaputirwa nemafuta akasarudzika kuderedza kukweshana pakati pepushrod neimba. Muchando chakanyanya, mafuta akajairwa anogona kukora kusvika pakusimba "kwakasimba", zvichiwedzera simba rinodiwa kufambisa piston yemukati. Kuramba uku kwemuchina kunoguma nekunonoka kwenguva yekupindura kwebhureki, izvo zvine njodzi panguva yekukurumidza. Nyanzvi dzeindasitiri kuMubatanidzwa wekuchengetedza mota dzekutengesa (CVSA)simbisa kuti chero kunonoka kwekushandisa mabhureki kunogona kuwedzera daro rekumira nemamita akati wandei mumigwagwa ine chando.

Mibvunzo Inowanzo bvunzwa (Mibvunzo Inowanzo bvunzwa)
1. Sei mabhureki erori rangu achitora nguva yakareba kuti asunungurwe kana kuchitonhora?
Kunonoka kuburitswa kunowanzo kukonzerwa nemafuta akakora kana kuti kuumbwa kwechando mukati mekamuri remabhureki. Chitubu chemukati chekudzoka chinofanira kukunda kuramba uku kwakawedzera kuti chidzore pushrod kumashure. Kuti udzivise izvi, iva nechokwadi chekuti air dryer yako inoshanda uye shandisa mafuta anodziya anopisa zvishoma panguva yekugadzirisa nguva dzose.
2. Diaphragm yekamuri rebhureki rakatsemuka inogona kugadziriswa kwenguva pfupi here?
Kwete, diaphragm yakatsemuka haigone kugadziriswa uye inofanira kutsiviwa nekukasika. Kunyangwe kudonhedza kwegomba kunogona kukonzera kurasikirwa nesimba rekubhureka pavhiri iroro. Gara uchitsvaga chinotsiva chemhando yepamusoro kubva kukambani inotengesa bhureki kuti uve nechokwadi chekuti chikamu chitsva ichi chinosangana nezvinodiwa zvekuchengetedza.
3. Ndingaziva sei kana kamuri rangu remabhureki echitubu richidonhedza mvura mukati?
Ita bvunzo yekudonhedza mvura (leak down test) nekuchaja system, kudzima injini, uye kutarisa mageji emhepo nebhureki rekupaka rakaburitswa. Kana kumanikidzwa kwacho kukadonha kupfuura 2-3 PSI paminiti, shandisa mvura ine sipo kuti uone kana mhepo iri kubuda mumaburi emukamuri.
4. Munyu wemumugwagwa unokanganisa hupenyu hwekamuri remabhureki here?
Ehe, munyu wemumugwagwa uye mvura inobvisa ngura zvakanyanya paimba yesimbi nepabhokisi rekeji. Nekufamba kwenguva, ngura inogona kushayisa simba chimiro chekamuri. Kusarudza fekitori yezvikamu zvemarori ekuChina ine machira ekudzivirira ngura akanakisa kunogona kuwedzera hupenyu hwechikamu.
5. Pane mhando chaiyo yekamuri remabhureki here yemamiriro ekunze kweArctic?
Kunyange zvazvo paine makamuri e "Arctic grade", chinhu chinonyanya kukosha idiaphragm nemafuta emukati. Tsvaga mayuniti akanyorwa zvakananga kuti ashande pakupisa kwakaderera, ayo anoshandisa makemikari erabha akasarudzika anoramba achichinjika pa -40°C kana pasi kudzivirira mhepo kupfuura.
