Zifukwa zotani za kutayikira kwa mafuta mu retarder?

Ma retarders ndi chida chodziwika bwino cha makina ndi zida m'mafakitale opangira. Kuphatikiza pa kuwononga katundu, kutayikira kwamafuta kumatha, pakachitika zovuta kwambiri, kumapangitsa kuti mafuta azikhala ochepa komanso mafuta ochepetsera magiya. Kuwonongeka kwa giya yopatsirana pokwerera kumawonjezeka, zomwe zingayambitse kung'ambika kwa mano kapena kutsekeka komanso ngozi zokhudzana ndi makina. Chifukwa chiyani mafuta akutuluka mu retarder? Ndigawana zomwe ndikudziwa pamutuwu ndi aliyense lero pofuna kulimbikitsa ndi kuthandiza anzathu ndi makasitomala.

1. Kuthamanga kwapakati komwe kumachitika mkati ndi kunja kwa retarder

Mu retarder yotsekedwa, kukangana pakati pa magiya awiri aliwonse kumapangitsa kutentha. Malinga ndi lamulo la Boyle, kutentha mu bokosi la retarder kumakwera pang'onopang'ono ndi kuwonjezeka kwa nthawi yothamanga, pamene voliyumu mu bokosi la retarder silingasinthe. Chifukwa chake, pakuwonjezeka kwa mphamvu yogwira ntchito ya thupi lamilandu, mafuta opaka mafuta pamutu wamilandu amatuluka ndikuwaza pakatikati pa malo ochepetsera liwiro. Mafuta opaka mafuta amawululidwa kuchokera pampata chifukwa cha kusiyana kwapakati.

2. Mapangidwe onse a retarder si asayansi

Palibe chotchingira mpweya wachilengedwe pa retarder, ndipo pulagi yolowera ilibe pulagi yopumira. Kumanga kwamafuta ndi kumveka kwa mphete yamtundu wa shaft shaft kumasankhidwa chifukwa kapangidwe kake ka chisindikizo cha shaft sisayansi. Kusindikiza kusindikiza sikuthandiza pakanthawi kochepa chifukwa cha kupatuka kwa zinthu zolipirira zomwe zimamveka. Ngakhale poyambira mafuta amabwerera kumalo olowera mafuta, ndikosavuta kutsekereza, zomwe zimalepheretsa momwe mafuta amagwirira ntchito ndi mpope. Ma castings sanali okalamba kapena kuzimitsidwa panthawi yonse yopanga ndi kupanga ndi kupsinjika kwa kutentha komwe sikunathetsedwe, zomwe zimapangitsa kuti pakhale kusintha. Kutayikira kwamafuta kuchokera pamphambano kumachitika chifukwa cha zolakwika monga mabowo amchenga, timabowo tating'onoting'ono, zolowera mpweya, ming'alu, etc. Kutayikira kwamafuta kuchokera pamphambano kumachitika chifukwa cha zolakwika ngati mabowo amchenga, timabowo tating'onoting'ono, zolowera mpweya, ming'alu, ndi zina. kuchulukirachulukira kungakhale gwero la vutolo.

3. Kuchuluka kwa mafuta owonjezera

Panthawi yonse ya ntchito ya retarder, dziwe lamafuta limagwedezeka mwamphamvu, ndipo mafuta opaka mafuta amatuluka paliponse pathupi. Ngati kuchuluka kwa mafuta kumakhala kochulukirapo, kumapangitsa kuti mafuta ambiri aziwunjikana mu chisindikizo cha shaft, malo olumikizirana mano, ndi zina zotere, zomwe zimayambitsa kutayikira.

4. Ukadaulo wosauka ndi kukonza kukonza

Wobwezeretsayo amayenera kunyamula katundu wofunikira poyambitsa chifukwa cha kutayikira kwamafuta komwe kumabweretsa kutsika kocheperako. Ngati kachulukidwe kachulukidwe ka retarder sichikukwaniritsa zofunikira, mabawuti a maziko omwe ali ndi maziko a retarder amamasuka. Izi zidzakulitsa kugwedezeka kwa retarder ndikuwononga mphete yosindikizira pamtunda wapamwamba komanso wotsika kwambiri wa giya yochepetsera, zomwe zidzakulitsa kutulutsa kwamafuta. Kuphatikiza apo, kutayikira kwamafuta kumatha kuchitika chifukwa chosakwanira kuchotsa zinyalala zapamtunda, kugwiritsa ntchito molakwika zida zosindikizira, mawonekedwe olakwika a zisindikizo za hydraulic, komanso kulephera kuchotsa nthawi yomweyo ndikusintha zisindikizo za hydraulic panthawi yokonza makina ndi zida.
