Ivhavhavha yekudzivirira inoiswa pamidziyo, chigadziko kana pombi kuti udzivirire kuwandisa.Kana dzvinyiriro mumudziyo kana pombi inodarika kukosha kunobvumirwa, vharuvhu inovhurika otomatiki kuburitsa svikiro;Kana kudzvinyirirwa kunodonha kune iyo yakatarwa kukosha, iyo valve inovhara yega.
Iyo vharafu yekuchengetedza inogona kukamurwa kuita yakananga yekuita mhando uye mutyairi akashanda mhando zvinoenderana neakasiyana ekutyaira modhi.Iyo yakananga mhando inofambiswa zvakananga neiyo system pressure pane valve inlet.Panguva ino, inokunda kudzvinyirirwa kwepakati pasi pevhavha disc ne mechanical load inopiwa nechitubu kana nyundo inorema.Rudzi rwemutyairi runofambiswa nechimiro, chinoshandisa nzira yekuburitsa kana kushandisa simba rekuvhara kuvhura kana kuvhara vharafu yekuchengetedza.
Mavharuvhu ekuchengetedza anogona kukamurwa kuita:
1. Spring mhando yekuchengetedza vharafu
Shandisa simba rekumanikidzika chitubu kuti uenzanise kudzvinyirira kwevhavha disc, kuitira kuti valve yekuchengetedza yakavharwa.Ivhavhavha yekudzivirira ine zvakanakira zvekunzwa kwakanyanya, kutakura uye isina muganho yekuisa chinzvimbo.Rudzi urwu rwevhavha yekudzivirira inowanzoshandiswa.Izvo zvakashata ndezvekuti simba rekumanikidza rechirimo rinoshanduka ne deformation yechirimo.Kana tembiricha yakakwira, chitubu chine kupisa kwekudzivirira uye matambudziko ekupisa kupisa.
2. Lever uye inorema nyundo yekuchengetedza vharafu
Simba resando rinorema rinowedzerwa nerevheti uye rinotakurwa pavhavha disc.Iyo inobatsira ndeyokuti simba rinotakurwa pavhavha disc rinoramba risina kuchinja panguva yekuvhura nekuvhara kwevhavha.Izvo zvakashata ndezvekuti inonzwa kune vibration uye ine isina kunaka reating performance.Inowanzoshandiswa pamichina yakagadziriswa.
3. Pulse mhando yekuchengetedza vharafu
Ivhavha huru uye vheji yekubatsira zvakagadzirirwa pamwe chete kutyaira iyo huruvhavha kuburikidza nekuputika kwekuita kwevhavha yekubatsira.Inowanzoshandiswa muhupamhi hwakakura, kutama kukuru uye hurongwa hwepamusoro-soro.
