Mukutanga kwema1900 - panguva iyo ngarava dzemugungwa dzakatanga kuedza neinjini dzedhiziri - imwe tsvakiridzo yakakosha yaive ichibuda kune imwe magumo emutsetse wepropeller shaft.
Muchikamu chekutanga chezana remakore rechimakumi maviripombi mechanical chisimbisoyakava mucherechedzo wepakati pakati pekugadzirisa shafting mukati mechikepe chechikepe uye zvikamu zvinoratidzwa mugungwa. Iyo tekinoroji nyowani yakapa kuvandudzwa kunoshamisa mukuvimbika uye kutenderera kwehupenyu zvichienzaniswa nemabhokisi ekuisa zvinhu uye zvisimbiso zvegland izvo zvaive zvakatonga musika.
Iko kuvandudzwa kweshaft mechanical seal tekinoroji inoenderera mberi nhasi, iine tarisiro yekusimudzira kuvimbika, kuwedzera hupenyu hwechigadzirwa, kuderedza mutengo, kurerutsa kuisirwa uye kuderedza kugadzirisa. Zvisimbiso zvemazuva ano zvinodhirowa pazvinhu-zve-iyo-zvigadzirwa, dhizaini nekugadzira maitiro pamwe nekutora mukana wekuwedzera kubatana uye kuwanikwa kwedata kugonesa kutarisisa kwedhijitari.
PamberiMechanical Seals
Shaft mechanical sealsyaive nhanho inoshamisa kumberi kubva kune yaimbove nesimba tekinoroji yakaiswa kudzivirira mvura yegungwa kuti isapinda muhull yakatenderedza propeller shaft. Bhokisi rekuisa zvinhu kana kuti ganda rakatakurwa rine zvinhu zvakarukwa, zvakaita setambo izvo zvinosungirirwa kutenderedza shaft kuita chisimbiso. Izvi zvinogadzira chisimbiso chakasimba ichibvumira shaft kutenderera. Zvisinei, pane zvipingamupinyi zvakati kuti izvo mechanical seal yakagadziriswa.
Friction inokonzerwa neshaft inotenderera ichipokana nekurongedza inotungamira kupfeka nekufamba kwenguva, zvichikonzera kuwedzera kudonha kusvika kurongedza kwagadziriswa kana kutsiviwa. Zvakatonyanya kudhura kupfuura kugadzirisa bhokisi rekuisa zvinhu kugadzirisa danda repropeller, iro rinogona kukuvadzwa nekukwesha. Nekufamba kwenguva, kupfekedza kungangopfeka groove mugomba, izvo zvinogona kupedzisira zvakanda iyo yese propulsion hurongwa kunze kwekurongeka, zvichikonzera kuti ngarava inoda yakaoma docking, shaft kubviswa uye kutsiva sleeve kana kunyange shaft kuvandudzwa. Chekupedzisira, pane kurasika kwekuita basa rekufambisa nekuti injini inoda kuburitsa simba rakawanda kushandura shaft inopesana neiyo yakanyatso kurongedza gland, kutambisa simba uye mafuta. Izvi hazviremekedzi: kuti uwane inogamuchirika mareti ekudonha, iyo stuffing inofanira kusimba kwazvo.
Iyo yakarongedzwa gland inoramba iri nyore, inotadza kuchengetedza sarudzo uye inowanzo wanikwa mumakamuri mazhinji einjini yekuchengetedza. Kana chisimbiso chikatadza kushanda, chinogona kugonesa ngarava kuti ipedze basa rayo yodzokera pachiteshi kuti igadziriswe. Asi iyo mechanic yekupedzisira-chiso chisimbiso chakavakirwa pane iyi nekusimudzira kuvimbika uye kuderedza kuvuza zvakanyanya zvakanyanya.
Pakutanga Mechanical Zvisimbiso
Shanduko yekuisa chisimbiso kumativi anotenderera yakauya nekuziva kuti kugadzira chisimbiso padivi pe shaft - sezvinoitwa nekurongedza - hazvina basa. Nzvimbo mbiri - imwe inotenderera ine shaft uye imwe yakagadziriswa - yakaiswa perpendicular kune shaft uye yakamanikidzwa pamwe chete ne hydraulic uye mechanical forces inogona kuumba chisimbiso chakanyanya kuoma, kuwanikwa kunowanzonzi kune injiniya George Cooke muna 1903. Yekutanga kushambadzira mechanical zvisimbiso yakagadzirwa muna 1928 uye yakashandiswa kune centrifugal pombi uye compressors.
