1. Vhuru yegedhi: Vhuru yegedhi inoreva vharuvhu ine chikamu chinovhara (gedhi) inofamba ichitevedza nzira yakatwasuka yeakisi yechaneli.Inonyanya kushandiswa senzira yekucheka mupombi, kureva, yakazaruka zvakakwana kana yakavharwa zvakakwana.Kazhinji, mavharuvhu emagedhi haafaniri kushandiswa kugadzirisa kuyerera.Inogona kushandiswa kune yakaderera tembiricha kudzvanywa kana yakakwirira tembiricha uye kumanikidza, zvichienderana valve zvinhu.Asi mavharuvhu emagedhi haawanzo shandiswa kutakura madhaka uye mamwe midhiya mupombi.
Zvakanakira:
(1) kushomeka kwemvura;
② Torque inodiwa kutanga nekuvhara idiki;
(3) Inogona kushandiswa mukuyerera kwepakati kune maviri mativi emhete network network, kureva kuti, kuyerera kwepakati hakudzivirirwe;
(4) kana yakazaruka zvizere, nzvimbo yekuisa chisimbiso inonyungudutswa nepakati yekushanda idiki pane yekumisa vharafu;
Chimiro chechimiro chiri nyore, yakanaka kugadzira tekinoroji;
Kureba kwechimiro kupfupi.
Zvakaipa:
(1) Saizi uye kureba kwekuvhura kwakakura, nzvimbo inodiwa yekuisa zvakare yakakura;
(2) mukuita kwekuvhura nekuvhara, iyo yekuvharisa pamusoro pekukwenya, kurasikirwa kwekukwesha kwakakura, uye kunyange nyore kukonzera abrasion chiitiko pakupisa kwepamusoro;
(3) Ivhavhavha yegedhi ine mbiri yekuisa chisimbiso pakugadzirisa, kugaya uye kugadzirisa kwakawedzera mamwe matambudziko;
④ Nguva yakareba yekuvhura nekuvhara.

Nortech ndeimwe yeanotungamira maindasitiri ekugadzira mavharuvhu muChina ane quality certification ISO9001.
