Yambiro Yakakosha: Ichi chinyorwa chemudura renhoroondo, kwete zvemuchina wazvino uno, maverengero ehuwandu, kuongorora njodzi kana bhuku rekushandisa. Nzira dzekusimbisa, modhi, hukuru, kumhanya, mafomula, vaedzi uye maitirwo anofanirwa kutariswa zvinoenderana nemirau inoshanda, zvinyorwa zvemugadziri uye mitemo yebasa yakachengeteka.

Ichi chinyorwa hachisi chekupihwa kwemichina, vaedzi kana sevhisi zvinyorwa zveSavo Kusić. Ikozvino kupihwa kwakanangana nemahwindo, magonhi neanobatanidzwa mhinduro.

Kusimbisa saha mufuremu

Nemagetsi, masaha anofanirwa kunge akachengetedzwa zvakanaka uye akatsikirirwa mufuremu. Paunenge uchishanda nemasaha asina kusimba, shard iri muchimiro chewavy cut, nezvimwewo inowanikwa. Nzira yakajairika yekusimbisa saha ndeye wedge, eccentric, screw (Fig.1), uyewo nzira yekusimbisa kushandisa hydraulic devices. Kuomesa saha nema wedge kwakaipa kupfuura dzimwe nzira. Nhamba huru yemaindasitiri inoburitsa nhamba huru yemhando dzemasaha ane simba, anokurumidza kufamba, anobereka zvakanyanya. Aya mafekitari anogadzirwa zvakanyanya anoshanda mumiti mikuru yekugadzira matanda muindasitiri yekuvaka. Hunhu hwehunyanzvi hweaya gaiters anopiwa mutafura1.

Kugadzirwa kweGator kunoverengerwa zvinoenderana neformula: P = K -  Δtnq/1000L m3. Iko K ndiyo gedhi rekushandisa coefficient. Kumachira akagadzirwa K = 0.93, uye esemi-mechanised K = 0.90;  Δ - kutamira kune imwe kutendeuka kwegedhi shaft; n - nhamba yekuchinja kwegedhi shaft paminiti; t - gater kushanda nguva mumaminitsi; q - log volume, m3; L - kureba kwematanda, m.

Nhoroondo kuverenga kwekubudirira

Paunenge uchitarisa avhareji yegore rekugadzirwa kwegedhi rekuchinja kumwe chete, kumira, kunoitika nekuda kwezvikonzero zvakasiyana (kugadzirisa, kushaikwa kwezvinhu zvakagadzirwa, nezvimwewo) zvinofanirwa kuverengerwa. Kurasikirwa uku kunotemerwa nechiyedzo coefficient Kgod = 0.9 - 0.92.

Saka, avhareji yegore negore yekubudirira kwemuchengeti wegedhi pashift imwe chete inotsanangurwa neformula P = Kgod x K x Δntq/1000L m3 yeshift imwe chete.
