4. Simba rekusimudza uye nguva yekusimudza:

Kuvhura nekuvhara simba uye kuvhura nekuvhara torque zvinoreva simba kana nguva inofanirwa kushandiswa kuvhura kana kuvhara valve.Kana uchivhara vharuvhu, zvinodikanwa kuti ugadzire imwe chisimbiso chakananga kudzvanywa pakati pekuvhura nekuvhara zvikamu uye maviri ekuisa chisimbiso chechigaro, uye panguva imwe chete kukurira gaka riri pakati pevhavha hunde uye kurongedza, tambo pakati pechigaro. Dzinde revharuvhu uye nati, uye chitsigiro chiri kumagumo kwehunde yevharuvhu.Iyo frictional force yezvimwe zvikamu zvekukwesha, saka, imwe simba rekuvhara uye torque yekuvhara inofanira kuiswa.Munguva yekuvhura nekuvhara nzira yevhavha, iyo inodiwa yekuvhura nekuvhara simba uye kuvhura nekuvhara torque inoshandurwa, uye iyo yakanyanya kukosha ndeye iyo yekupedzisira phosphorus yakavharwa kana Iyo yekutanga nguva yekuvhura.Paunenge uchigadzira uye kugadzira mavharuvhu, edza kudzikisa simba ravo rekuvhara uye torque yekuvhara.
5. Kuvhura nekuvhara kumhanya:
Kuvhura nekuvhara kumhanya kunoratidzwa nenguva inodiwa kuti valve ipedze kuvhura kana kuvhara.Kazhinji, hapana zvinonyanya kudiwa pakuvhura uye kuvhara kwevhavha, asi mamwe mamiriro ekushanda ane zvakakosha zvinodiwa pakuvhura nekuvhara nekukurumidza.Kana zvimwe zvinoda kukurumidza kuvhura kana kuvhara kudzivirira njodzi, zvimwe zvinoda kuvhara zvishoma nezvishoma kudzivirira sando yemvura, nezvimwewo. Izvi zvinofanirwa kutariswa pakusarudza rudzi rwevharuvhu.
6. Chiito chekunzwa uye kuvimbika:
Izvi zvinoreva kunzwisiswa kwevharuvhu mukupindura shanduko mumaparamita enhau.Nokuti mavharuvhu ane chaiwo mabasa akadai throttle mavharuvhu, kumanikidza kuderedza mavharuvhu, uye regulating mavharuvhu, uyewo mavharuvhu ane chaiwo mabasa akadai kuchengeteka mavharuvhu uye misungo, basa ravo senitivity uye kuvimbika zvinokosha chaizvo unyanzvi hwokugadzira kuita zviratidzo.
7. Hupenyu hwebasa:
Inoratidza kusimba kwevhavha, indekisi yakakosha yekuita yevhavha, uye ine kukosha kukuru kwehupfumi.Inowanzo kuratidzwa maererano nehuwandu hwekuzarura uye kuvhara kunogona kuvimbisa zvinodiwa zvekuisa chisimbiso, uye inogonawo kuratidzwa maererano nenguva yekushandisa.

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