Mikhalidwe Yogwirira Ntchito Yofanana Bwino: Njira Zazikulu ndi Buku Lothandiza Posankha Zonyamula Zotsika

 

Mu makina otumizira mauthenga, kutsetsereka kwa radialmaberiyandi zigawo zofunika kwambiri zothandizira ma shaft ozungulira. Kusankha kwawo mwanzeru kumakhudza mwachindunji kukhazikika ndi moyo wa chipangizocho. Popeza tikukumana ndi mikhalidwe yosiyanasiyana yogwirira ntchito, kodi tingapange bwanji zisankho zodziwa bwino kuti tipewe kuwononga kwambiri kapena kuwononga kwambiri?

 

Nkhaniyi ikupereka njira yosankhira mwadongosolo kutengera mbali zitatu: mtundu wa kapangidwe kake, kufananiza magawo ogwirira ntchito, ndi mawonekedwe a zinthu.

 

1. Kugawa m'magulu malinga ndi kapangidwe kake kuti kagwirizane ndi zofunikira pakukhazikitsa ndi kukonza

 

Kutsetserekamaberiyamakamaka amagawidwa m'magulu atatu:

 

Yogwirizana: Yopapatiza komanso yotsika mtengo, yoyenera kunyamula katundu wopepuka, liwiro lotsika, komanso kugwiritsa ntchito kosafunikira kusonkhanitsa ndi kumasula pafupipafupi, monga ma mota ang'onoang'ono ndi zida zapakhomo.

 

Kugawanika: Kosavuta kukhazikitsa ndi kusamalira malo ozungulira, komwe kumagwiritsidwa ntchito kwambiri pazida zapakati mpaka zazikulu, monga ma gearbox ndi ma compressor, zomwe zimafuna kukonzedwa nthawi zonse.

 

Kudzilungamitsa: Yokhala ndi ntchito yodzilungamitsa yokha, imathandizira kutembenuka kwa shaft kapena kupotoka kwa kuyika. Ndi yoyenera ma shaft aatali kapena nyumba zosinthika mosavuta ndipo imapezeka kwambiri m'makina olemera ndi makina oyendetsa sitima zapamadzi.

 

2. Gwiritsani ntchito ma curve odziwika bwino kuti muzindikire mwachanguchogwiriramitundu

 

Muzochita zauinjiniya, nthawi zambiri njira yosankha ma bearing imagwiritsidwa ntchito poyesa koyamba. Tchatichi chimagwiritsa ntchito liwiro la journal ngati mzere wopingasa ndi katundu pa gawo lililonse loyembekezeredwa ngati mzere wolunjika kuti ugawane magawo oyenera a ma bearing osiyanasiyana. Mwachitsanzo, pa liwiro lochepa ndi katundu wolemera, ma bearing odzola ndi madzi amakondedwa; pa liwiro lapakati ndi katundu wapakati, ma bearing ogawanika okhala ndi mafuta pang'ono amadzimadzi ndi chisankho chofala; pa liwiro lapamwamba ndi katundu wopepuka, ma bearing odzipaka okha kapena apulasitiki angagwiritsidwe ntchito kuchepetsa kukangana ndi kukwera kwa kutentha. Mwa kuyang'ana tebulo (monga ma chart osankha mu miyezo yamakampani), opanga amatha kuchotsa mwachangu mitundu yosayenera, ndikuwonjezera magwiridwe antchito osankha.

 

3. Kuyerekeza magwiridwe antchito kumatsimikizira kudalirika kwa ntchito

 

ZosiyanachogwiriraZipangizozo ndizoyenera malo osiyanasiyana ogwirira ntchito: Ma bearing a ufa: Amadzipaka okha mafuta ndipo ndi oyenera malo opanda mafuta kapena malo opanda mafuta ambiri, koma ndi ofooka ndipo amagwiritsidwa ntchito kwambiri pazida zopepuka komanso zosagwira ntchito. Ma bearing apulasitiki (monga ma bearing a POM ndi PTFE): Ndi osagwirizana ndi dzimbiri, safuna phokoso lalikulu, ndipo safuna mafuta ambiri, koma ali ndi kukhazikika koipa kwa kutentha ndipo ndi oyenera malo onyowa, aukhondo, kapena kukonza chakudya. Ma bearing okhala ndi Babbitt: Amapereka mphamvu yolimba yonyamula katundu komanso kutsatira malamulo abwino kwambiri, zomwe zimapangitsa kuti akhale chisankho chabwino kwambiri pazida zolemera komanso zothamanga kwambiri. Komabe, ndi okwera mtengo kwambiri ndipo amafunikira njira yopaka mafuta.

 

KutsetserekachogwiriraKusankha sikumatsimikiziridwa ndi gawo limodzi; ndi kusiyana kwakukulu pakati pa mtundu wa kapangidwe kake, momwe ntchito ikuyendera, ndi katundu wa zinthu. Opanga mapulani akulangizidwa kugwiritsa ntchito machati osankha kuti achite kafukufuku woyambirira kutengera liwiro lenileni, katundu, malire a malo, ndi nthawi yokonza. Kenako, ayenera kuyerekeza katundu wa zinthu kuti pamapeto pake adziwe yankho labwino kwambiri. Kwa oyamba kumene, kudziwa bwino njira yoyendetsera ntchitoyi kungathandize kwambiri kukonza bwino kapangidwe kake komanso kudalirika kwake.
