1, kana uchiburitsa kesi zvinoenderana nerondedzero yekurongedza kuti utarise kuti zvishongedzo zvakwana, tarisa zvikamu zvemuchina kana paine yakasununguka screw.
Union unitary type vacuum yekuisa chisimbiso muchina unofanirwa kutarisa kana organic girazi kavha uye inotenderera inoshanduka, kamuri mbiri inofanirwa kutarisa inochinjika vacuum chivharo tendeuka kurudyi kana kuruboshwe.
2, pamberi pebhutsu, zvikamu uye gomba reoiri pachiitiko ichi, ichichaja yakadzikama yemafuta ekuzora emhino, panguva imwe chete, zvinoenderana nebhuku rekutsvaira pombi kuunza vacuum pombi yemafuta, jekiseni remafuta asi ne achitarisa pafafitera repombi yekutsvaira.
Chenjerera kune yakaderera mafuta emukati yevacuum pombi yekumhanya nguva inofanirwa kuita kuti mafuta ezinga remafuta asadzike pane iyo mafuta hwindo kureba kwe1/2, mafuta akakwira anofanira kugadzira mafuta mwero wemafuta wehwindo hauna kukwira kupfuura. 3/4 yehurefu hwehwindo remafuta.
3, vacuum dhigirii kugadzirisa
maererano nekudiwa kwezvinhu zvakaputirwa sarudzo yenguva yekudhonza kuti uwane iyo yakakodzera vacuum dhigirii, iyo yakareba nguva yekubvisa inowanikwa nepamusoro vacuum degree, zvichienderana nemhedzisiro yekushanda.
4, tembiricha yekuisa chisimbiso chekupisa uye kugadzirisa kwekupisa kwekuvhara nguva
zvinoenderana nekusiyana kwezvinhu zvakaputirwa uye zvekurongedza zvinhu, isa yakakodzera kupisa yekuisa chisimbiso nguva uye tembiricha forogo kuti uwane chisimbiso simba rekongiri zvinoenderana neiyo chaiyo jostle yemhedzisiro.
