Maoko anoita basa rakakosha mukugadzira basa rekuita. Nekudaro, maoko zvakare zvikamu zvinokuvara nyore, zvichiverengera nezve 25% yehuwandu hwehuwandu hwekukuvadzwa kwemaindasitiri. Moto, tembiricha yepamusoro, magetsi, makemikari, zvinokanganisa, kucheka, mabrasions, uye kutapukira zvinogona kukuvadza maoko. Kukuvara kweMechanical sekukanganisa nekuchekwa kunowanzoitika, asi kukuvara kwemagetsi uye kukuvara kwemwaranzi kwakakomba uye kunogona kukonzera kuremara kana kufa. Kudzivirira maoko evashandi kubva pakukuvadzwa panguva yebasa, basa remagirovhosi ekudzivirira rinonyanya kukosha.
Dziviriro magirovhosi inspection reference standards
Muna Kurume 2020, European Union yakaburitsa chiyero chitsva:EN ISO 21420: 2019General zvinodiwa uye nzira dzekuyedza dzemagurovhosi ekudzivirira. Vagadziri vemagurovhosi ekudzivirira vanofanirwa kuona kuti zvinhu zvinoshandiswa kugadzira zvigadzirwa zvavo hazvikanganise hutano hwevashandisi. Iyo itsva EN ISO 21420 chiyero inotsiva iyo EN 420 yakajairwa. Uye zvakare, EN 388 ndeimwe yeEuropean zviyero zvemaindasitiri ekudzivirira magurovhosi. European Committee for Standardization (CEN) yakabvumidzwa shanduro EN388: 2003 muna Chikunguru 2, 2003. EN388:2016 yakaburitswa muna Mbudzi 2016, ichitsiva EN388:2003, uye iyo yekuwedzera vhezheni EN388: 2016 + A1: 2018 yakadzokororwa 18 mu20.
Zviyero zvinoenderana nemagurovhosi ekudzivirira:
EN 388: 2016 Mechanical mwero wemagirovhosi ekudzivirira
TS EN ISO 21420: 2019 General zvinodiwa uye nzira dzekuyedza dzemagurovhosi ekudzivirira
EN 407 Yakajairwa yemoto uye kupisa magurovhosi
TS EN 374 Zvinodiwa zvemakemikari ekupinda kuramba kwemagurovhosi ekudzivirira
TS EN 511 Regulatory zviyero zveinotonhora uye yakaderera tembiricha inodzivirira magirovhosi
EN 455 Dziviriro magurovhosi ekukanganisa uye kucheka dziviriro
Magirovhosi anodziviriranzira yekuongorora
Kuti uchengetedze kuchengetedzeka kwevatengi uye kudzivirira kurasikirwa kune vatengesi kunokonzerwa nekuyeuka nekuda kwezvinhu zvemhando yechigadzirwa, magurovhosi ese ekudzivirira anotumirwa kune dzimwe nyika dzeEU anofanirwa kupasa zvinotevera ongororo:
1. Pa-saiti mechanical performance test
EN388:2016 Tsanangudzo yeLogo
| Level | Level1 | Level2 | Level3 | Level4 |
| Pfeka marevolutions | 100 rpm | 500pm | 2000pm | 8000pm |
1.1 Abrasion kuramba

Iyo TDM yekucheka bvunzo inoshandisa blade kucheka magirovhosi emichindwe nekumhanya nguva dzose. Inoedza kureba kwekufamba kweblade kana ichicheka nemuenzaniso pasi pemitoro yakasiyana. Inoshandisa mafomula esvomhu chaiwo kuverenga (kutsvedza) kuwana huwandu hwesimba rinoda kushandiswa kuita kuti blade ifambe 20mm. Cheka sampuli kuburikidza.
Muedzo uyu chinhu chitsva chakawedzerwa mu EN388:2016 vhezheni. Chiyero chemhedzisiro inotaridzwa seAF, uye F ndiyo yepamusoro-soro. Kuenzaniswa ne EN 388: 2003 coupe bvunzo, TDM bvunzo inogona kupa yakanyatso shanda kucheka kuramba kuita zviratidzo.
5.6 Impact kuramba (EN 13594)
Hunhu hwechitanhatu hunomiririra kuchengetedzwa kwekukanganisa, inova bvunzo yekusarudza. Kana magirovhosi akaedzwa kudzivirira kukanganisa, ruzivo urwu rwunopihwa netsamba P sechiratidzo chechitanhatu uye chekupedzisira. Pasina P, girovhosi haina kudzivirirwa.
2. Kuongororwa kwekuonekwazvemagirovhosi ekudzivirira
-Zita remugadziri
- Magurovhosi uye saizi
- CE certification chiratidzo
- EN yakajairika logo dhizaini
Aya mamakisi anofanirwa kuramba achiverengeka kwehupenyu hwese hwegirovhosi
3. Magirovhosi anodzivirirakurongedza kwekuongorora
- Zita nekero yemugadziri kana mumiriri
- Magurovhosi uye saizi
- CE chiratidzo
-Iyo ndiyo yakarongerwa danho rekushandisa / rekushandisa, semuenzaniso "kune ngozi shoma chete"
- Kana girovhosi ichingopa dziviriro kune imwe nzvimbo yeruoko, izvi zvinofanirwa kutaurwa, semuenzaniso "kuchengetedzwa kwemichindwe chete"
4. Magirovhosi anodzivirira anouya nemirayiridzo kana mabhuku ekushandisa
- Zita nekero yemugadziri kana mumiriri
- Zita regurovhosi
- Inowanikwa saizi renji
- CE chiratidzo
-Kuchengeta uye kuchengetedza mirayiridzo
-Mirairo uye zvisingakwanisi kushandiswa
- Rondedzero ye allergenic zvinhu mumagurovhosi
- Rondedzero yezvese zvinhu mumagurovhosi zviripo pakukumbira
-Zita uye kero yedare retifiketi rakasimbisa chigadzirwa
- Basic mwero
5. Zvinodiwa zvekusakuvadzazvemagirovhosi ekudzivirira
- Magurovhosi anofanira kupa yakanyanya kudzivirira;
- Kana pane seams pagurovhosi, kushanda kwegirovha hakufaniri kuderedzwa;
- pH kukosha kunofanira kuva pakati pe3.5 ne9.5;
- Chromium (VI) zvemukati zvinofanirwa kunge zvakaderera pane yekuona kukosha (<3ppm);
-Magurovhosi erabha echisikigo anofanirwa kuongororwa pamapuroteni anotorwa kuti ave nechokwadi chekuti haakonzerese kusawirirana mumunhu anopfeka;
- Kana mirairo yekuchenesa ichipihwa, mazinga ekuita haafanire kuderedzwa kunyangwe mushure mehuwandu hwehuwandu hwekugezwa.
Iyo EN 388: 2016 yakajairwa inogona kubatsira vashandi kuona kuti ndeapi magurovhosi ane mwero wakakodzera wedziviriro kubva kunjodzi dzemuchina munzvimbo yebasa. Semuenzaniso, vashandi vekuvaka vanogona kusangana nenjodzi yekupfeka uye kubvaruka uye vanoda kusarudza magirovhosi ane kukwirira kupfeka kusagadzikana, nepo vashandi vekugadzira simbi vanofanirwa kuzvidzivirira kubva pakucheka kukuvara kubva pakucheka maturusi kana kukwenya kubva kumicheto yesimbi inopinza, izvo zvinoda kusarudza magurovhosi ane mwero wepamusoro wekucheka kushorwa.
