Kutungamira kwemutoro, kumhanya, tembiricha yekushanda, kusvibiswa, nzira yekuzora, uye hupenyu hwebasa hunodiwa zvese zvinopesvedzera kana bearing ichizopa kushanda kwakavimbika kana kuti ikava nzvimbo yekukundikana kwekutanga. Chinyorwa chino chinotsanangura zvinodiwa zvikuru zvekusarudza mainjiniya nemapoka ekugadzirisa anofanira kuongorora, kusanganisira kuti mamiriro ekushandisa anokanganisa sei rudzi rwebheyaringi, kubviswa kwemukati, zvinhu, kuvhara, uye zvinodiwa nemazvo. Pakupedzisira, vaverengi vachave nehurongwa hunoshanda hwekutsanangura mabheyaringi ebhora anotsigira nguva yekushanda, kudzora mari yekugadzirisa, uye anokodzera zvinodiwa nenzvimbo chaiyo yekushanda.
Maitiro Ekusarudza Kutakura Mabhora
Kusarudza bhora rekushandisa muindasitiri kunoda nzira yakasimba yekugadzira zvinhu panzvimbo pekufananidza zviri nyore nekabhuku. Mutengo wekuva muridzi webheyaringi (TCO) webheyaringi yeindasitiri unowanzo pfuura mutengo wayo wekutanga wekutenga nechikamu cheshanu kusvika gumi kana uchitarisa basa rekuisa, nguva dzekuzora dzinoenderera mberi, uye kushandiswa kwesimba.
Ongororo yakarongeka inoita kuti zvikamu zvakasarudzwa zvienderane nezvinodiwa chaizvo, zvichiwedzera kuwanikwa kwezvinhu uye kudzivirira kutadza kushanda zvakanaka kwemichina.
Sei kusarudzwa kuchikanganisa nguva yekushandisa uye mari yekugadzirisa
Nguva yekumhanya ndiyo nzira huru yekuongorora purofiti yemaindasitiri. Mumaindasitiri anoenderera mberi nekushanda, nguva yekumhanya isina kurongwa inogona kukonzera mari inotangira pamadhora zviuru gumi kusvika pamusoro pemadhora zviuru zana paawa. Kukundikana kwemabheya nguva isati yakwana—kazhinji kunokonzerwa nekusarudzwa kwekutanga kusina kunaka maererano nekukwanisa kurema kana miganhu yekumhanya—kunokonzera zvakananga kudzimwa kwezvinhu uku kunodhura.
Uyezve, basa rekugadzirisa rinoita kuti pave nemari yakawanda inoshandiswa pakushanda. Kusarudza nzira inoshanda zvakanaka kunoderedza kuwanda kwemabasa emaoko, nokudaro zvichideredza mari yekugadzirisa uye kuderedza njodzi yekukanganisa kwevanhu panguva yekuchinjana kwakaoma.
Ndezvipi zvinodiwa pakushanda
Kutsanangura mashandiro emuchina ndiro danho guru mukuongorora mashandiro emuchina. Mainjiniya anofanirwa kuyera mamiriro chaiwo ekushanda, kusanganisira kumhanya kwemuchina, maprofile emutoro unoenderera mberi, uye tembiricha yekunze, iyo inowanzo tangira pa -40°C mukushandiswa kwe cryogenic kusvika pamusoro pe 200°C muzvitofu zvemaindasitiri zvinopisa zvakanyanya.
Mamiriro ezvinhu enguva pfupi, akadai sekuvhunduka kwemotokari panguva yekutanga kwemotokari kana kukwira kwekupisa kamwe kamwe, anofanirawo kurongwa nemazvo. Nekugadzira matrix chaiyo yeaya mashandisirwo ekushanda, maspecifiers anogona kuisa zvinodiwa zvekutanga zvesimba remutoro unochinja, mvumo yekuwedzera kwekupisa, uye miganhu yekunyorovesa mafuta.
