NSW API 602 vharuvhu yeglobhu, chikamu chinovhura nekuvhara chevharuvhu yegedhi resimbi yebhoniti yebhoti ndiro gedhi.Nzira yekufambisa yegedhi ndeye perpendicular kune nzira yemvura.Ivhavhavha yegedhi resimbi inogona kungovhurwa zvizere uye yakavharwa, uye haigone kugadziridzwa uye kurohwa.Gedhi revhavha yegedhi resimbi rakagadzirwa rine nzvimbo mbiri dzekuisa chisimbiso.Nzvimbo mbiri dzekuisa chisimbiso dzeakajairika mode gedhi vharafu dzinoumba chimiro che wedge, uye wedge angle inosiyana nemaparamita evharuvhu.Iwo madhiraivha mavharuvhu efodhi esimbi gedhi ndeaya: bhuku, pneumatic, magetsi, gasi-mvura yekubatanidza.
Iyo yekuisa chisimbiso pamusoro peyakagadzirwa simbi gedhi valve inogona kuiswa chisimbiso chete nepakati kudzvanywa, ndiko kuti, iyo yepakati pressure inoshandiswa kudzvanya chisimbiso pamusoro pegedhi kune chigaro chevhavha kune rumwe rutivi kuti ive nechokwadi chekuisa chisimbiso, icho chiri kuzvisimbisa.Mazhinji mavharuvhu emagedhi anomanikidzwa kuvhara, ndiko kuti, kana vharuvhu yakavharwa, zvinofanirwa kumanikidza gedhi ndiro kurwisa chigaro chevhavha nechisimba chekunze kuti ive nechokwadi chekuvharirwa kwechisimbiso chepamusoro.
Gedhi revharuvhu yegedhi rinofamba zvakatevedzana netsinde yevharuvhu, inodaidzwa kunzi lift rod gedhi vharuvhu (inonziwo vharanda regedhi rakavhurika).Kazhinji pane tambo yetrapezoidal padanda rekusimudza.Iyo nati inofamba ichibva pamusoro pevharuvhu uye girovha rinotungamira pamutumbi wevharuvhu kuti uchinje kutenderera kwekufamba kuita mutsara wekufamba, ndiko kuti, torque yekushandisa ichipinda mukusundira kwekushanda.
Zvakanakira forged simbi gedhi vharuvhu
1. Low fluid resistance.
2. Simba rekunze rinodiwa pakuvhura nekuvhara idiki.
3. Nzira yekuyerera kwepakati haina kudziviswa.
4. Kana yakazaruka zvakakwana, kukukurwa kwechisimbiso chepamusoro nepakati yekushanda idiki pane yevhavha yeglobhu.
5. Chimiro chiri nyore uye nzira yekukanda yakanaka.
