Kodi chokwera chosinthika ndi chiyani?

	Chokwera chamakono chosinthika chimakhala ndi chogwirizira chomwe chitha kusinthidwa mpaka 180 ° ndikukhazikika pamakona omwe mukufuna. Zitsanzo zina zimakhala ndi tsinde lothako lomwe limalola wogwiritsa ntchito kukulitsa kapena kufupikitsa tsinde lake mpaka 315 mm (12.5 mainchesi).
	Mtundu uwu wa shank uli ndi shank yozungulira kuti ikhale yosavuta kugwiritsa ntchito ndi chuma chopanga, ndipo imakhala ndi chogwirira osati chachiwiri kapena nsonga; zogwirira zina ndi nthiti kuti agwire mowonjezera.
	Chikhadabocho chimapindika kuti chichepetse chiwopsezo cha kuwonongeka kwa chinthu poyang'ana. Komabe, chifukwa cha kusowa kwa misomali kapena chokokera misomali, sichingagwiritsidwe ntchito kuchotsa misomali.
	Phazi losinthika limapangitsa shank iyi kukhala yosunthika kwambiri pazinthu zingapo zowunikira komanso ntchito zowongolera; popeza mudzatha kuzolowera chikhadabo chowongoka kapena chopindika, sipafunikanso chikhadabo chachiwiri.
	Zikhadabo zakuthwa zimatha kugwiritsidwa ntchito kukweza ndi kubweza zinthu pamalo olimba, komanso kukulitsa ngodya ya lever ngati pakufunika.
	Ma Gripper osinthidwa pamakona a obtuse amatha kugwiritsidwa ntchito kubweza zinthu mofatsa ngati pakufunika mphamvu zochepa, kapena kukweza ndi kusuntha zinthu patali pang'ono.
	Tsinde lobwezeredwa limalola wogwiritsa ntchito kuwonjezera ndi kuchepetsa kutalika kwa tsinde. Chifukwa tsinde lalitali limapereka mphamvu zambiri, kukulitsa tsinde kumapangitsa kuti tsinde likhale losavuta komanso losavuta (onani: Chidziwitso chokhudza mphamvu ndi kutalika). Kuchotsa shaft kudzapatsa wogwiritsa ntchito mphamvu zambiri pa bar; zabwino kugwiritsa ntchito ndendende.
	Nsagwada zosinthika zokhala ndi ma shaft osakulitsa zimapezeka muutali wa 250-380mm (10-15") komanso mitundu yowonjezereka imapezeka mu 600mm (23.5") kuphatikiza 315mm (12.5") yowonjezerapo.
	Ma barbell osakulitsa amatha kulemera kuyambira 370 mpaka 580 g (13 oz mpaka 1.3 lb). Mtundu wobwezeretsedwa umalemera 2.05 kg (4 lb 8 oz).
	Poyerekeza, izi zikutanthauza kuti cholemba chopepuka kwambiri chosinthika chimalemera ngati mbewa wamba yamakompyuta ...
	…pamene chachikulu chimalemera pafupifupi ma pinti anayi a mkaka ndi chitini cha mandimu…
	… ndipo chitsanzo chokulitsa chimalemera ngati nkhuku yathunthu.
Kodi ma mounts osinthika amapangidwa ndi chiyani?
	Mipiringidzo yosinthika imapangidwa kuchokera ku chrome vanadium steel, mtundu wa aloyi wachitsulo womwe uli ndi carbon, manganese, phosphorous, sulfure, silicon, chromium, ndi vanadium. Itha kutchedwanso "chrome vanadium steel".
	Kukhalapo kwa chromium ndi vanadium mu aloyi kumapangitsa chitsulo kukhala cholimba kwambiri - izi zikutanthauza kuti imatha kuuma (kupangidwa molimba) mokulirapo kuposa zitsulo zina.
	Ubwino wa chromium ndikuti umathandizira kukana abrasion, oxidation ndi dzimbiri, pomwe kuwonjezera kwa kaboni (omwe umapezeka muzitsulo zambiri zazitsulo) kumathandizira kukhazikika.
	Kutanuka kwabwinoko kumatsimikizira kuphulika komwe kungabwere chifukwa cha kuumitsa chitsulo ndipo kumatanthauza kuti chida chimatha kupindika kuposa kusweka ndi mphamvu yochulukirapo - yotetezeka kwambiri kwa wogwiritsa ntchito.
Kodi ma mounts osinthika amakutidwa ndi chiyani?
	Zokwera zosinthika zomwe zikuwonetsedwa pano ndi phosphate yokutidwa kuti isachite dzimbiri. Uwu ndi mtundu wa zokutira zotembenuza za crystalline zomwe zingagwiritsidwe ntchito pazitsulo zachitsulo monga zitsulo za alloy ndipo zimagwiritsidwa ntchito pamaso pa zokutira kapena kujambula.
	Chophimba chosinthika cha crystalline chimagwiritsa ntchito yankho lomwe limagwira mwachibadwa ndi pamwamba pa chinthu chachitsulo. Pachifukwa ichi, chisakanizo cha phosphoric acid ndi mchere wa phosphate chimagwiritsidwa ntchito pamwamba pa chidacho popopera mankhwala kapena kumizidwa mu kusamba, kupanga crystalline wosanjikiza wa phosphates umene sungathe kusungunuka kapena kutsukidwa.
	Kupaka kwa phosphate komweko kumakhala ndi porous ndipo sikungalepheretse dzimbiri kapena dzimbiri pokhapokha mutasindikizidwa ndi mafuta kapena chosindikizira china pambuyo pa ntchito. Ngati chidacho chikugulitsidwa ngati chosagwira dzimbiri komanso chokutidwa ndi phosphate, chosindikizira chosiyana chiyenera kuyikidwa pamwamba pa chidacho.
Kodi chokwera chosinthika chimagwiritsidwa ntchito chiyani?
Mipiringidzo yosinthika imatha kugwiritsidwa ntchito pofufuza, kukulitsa ndi kukweza mapulogalamu monga:
	Kukweza zitseko ndi matabwa
	Zotsegulira zotsegula
	Kudula zinthu zomangika mwamphamvu
	Kukweza paving slabs
	Kukweza pansi
