Zvigadzirwa zveokisijeni yakakosha yekumisa vharafu
Ichi chigadzirwa hachina basa revhavha yakajairika, asiwo ine maitiro ayo. Matanho akasimba ekurambidza oiri anotorwa panguva yekugadzira, uye zvikamu zvese zvinonyatso kucheneswa isati yaiswa. Iyo flange inoguma yeese saizi yemavharuvhu inopihwa conductive screw holes kudzivirira static magetsi. Izvo zvikamu zvakafumuka zvevhavha zvichachengetedzwa kubva kuguruva uye kusvibiswa kwemafuta. Zvinhu zvinoshandiswa mumhando iyi yezvigadzirwa zvakakamurwa kuita mapoka maviri: imwe inokandwa silicon ndarira inoshandiswa kumuviri wevharuvhu, bhoneti uye disc; imwe yacho isimbi yemhando yepamusoro-simbi inoshandiswa kumuviri wevharuvhu, bonnet uye disc.
