Kodi makina osindikizira ndi chiyani?

Makina amagetsi omwe ali ndi shaft yozungulira, monga mapampu ndi ma compressor, amadziwika kuti "makina ozungulira." Zisindikizo zamakina ndi mtundu wa kulongedza komwe kumayikidwa pa shaft yotumiza magetsi pamakina ozungulira. Amagwiritsidwa ntchito pazinthu zosiyanasiyana kuyambira pamagalimoto, zombo, ma roketi ndi zida zamafakitale, mpaka pazida zogona.

Zisindikizo zamakina zimapangidwira kuteteza madzi (madzi kapena mafuta) omwe amagwiritsidwa ntchito ndi makina kuti asadutse kumadera akunja (mlengalenga kapena madzi). Udindo wa zisindikizo zamakina umathandizira kupewa kuipitsidwa kwa chilengedwe, kupulumutsa mphamvu pogwiritsa ntchito makina oyendetsa bwino, komanso chitetezo pamakina.

Kuwonetsedwa pansipa ndi mawonekedwe a gawo la makina ozungulira omwe amafunikira kuyika chisindikizo cha makina. Makinawa ali ndi chotengera chachikulu ndi shaft yozungulira pakatikati pa chotengeracho (mwachitsanzo, chosakaniza). Chithunzichi chikuwonetsa zotsatira zamilandu yokhala ndi chisindikizo chomakina komanso popanda makina.

Milandu yokhala ndi popanda chisindikizo chamakina

Popanda chisindikizo

Madziwo amatuluka.

Ndi zonyamula gland (stuffing)

Axis amavala.

Pamafunika kuchucha (kudzoza) kuti zisawonongeke.

Ndi chisindikizo cha makina

Mzere suvala.
Palibe kutayikira kulikonse.

Kuwongolera kwamadzimadzi kumatchedwa "kusindikiza" mu makina osindikizira.

Popanda chisindikizo
Ngati palibe chisindikizo chosindikizira kapena kulongedza kwa gland, madziwo amadumphira pakati pa shaft ndi thupi la makina.

Ndi zonyamula gland
Ngati cholinga chake ndikungopewa kutulutsa kuchokera pamakina, ndikwabwino kugwiritsa ntchito chisindikizo chotchedwa gland kulongedza pa shaft. Komabe, chithokomiro chonyamula chilonda cholimba mozungulira tsindelo chimalepheretsa kusuntha kwa shaft, zomwe zimapangitsa kuti shaft iwonongeke, motero pamafunika mafuta opaka mafuta akamagwiritsidwa ntchito.

Ndi chisindikizo cha makina
Mphete zosiyana zimayikidwa pa shaft ndi makina opangira nyumba kuti alole kutayikira kochepa kwa madzi ogwiritsidwa ntchito ndi makina popanda kukhudza mphamvu yozungulira ya shaft.
Kuti izi zitheke, gawo lililonse limapangidwa molingana ndi kapangidwe kake. Zisindikizo zamakina zimalepheretsa kutayikira ngakhale ndi zinthu zowopsa zomwe zimakhala zovuta kuzigwira pamakina kapena pansi pamikhalidwe yovuta kwambiri komanso kuthamanga kwambiri.
