Zingwe zamagetsi - mitundu, cholinga, momwe mungasankhire

Wrench yamakokedwe ndi chida chogwirira dzanja poyang'anira kulumikizana kwa ulusi wolumikizidwa. Poika ma bomba, mutha kukumana ndi dzina losiyana la kiyi - "tared". Mawuwa amagwiritsidwa ntchito mofanana ndi ambuye m'mabungwe ofufuza. Pazinthu zina zapaintaneti, komanso m'mabuku akale aukadaulo, mutha kupeza kusiyana pakati pa mafungulo:

• Chida cha torque chimasinthidwa kuti chikhale cholimba china ndikudula katundu mukafika.
• Wrench ya torque imagwira ntchito zonse pamwambapa ndikuwonetsa makokedwe amakono pazithunzi za analog kapena digito.

 

Koma malingaliro onsewa adasinthidwa ndi opanga kuti asasokeretse ogula. Pali ma wrench ofunikira, ma wrenche ang'ono ndi magwiridwe antchito ena.

 

Chifukwa chiyani mukufunikira zingwe zamagetsi

 

M'mawu osavuta, chida cha torque chimafunika kuti musadule ulusi pazomangira. Mtedza, mabotolo, zomangira, zopyola komanso mabowo akhungu m'makonzedwe ali ndi malire awo olimba. Pakayimitsidwa kwambiri, ndipo makokedwe akumangirira osatha, zida zolumikizira ulusi zimatha kumeta ubweya paliponse paliponse. Kapenanso, chinthu chophatikizira chomata, nthawi zambiri chimakhala cholumikizira kapena chidutswa, chimachotsedwa kumunsi kwa ndodo kumutu.

Chofunikira ndichachidziwikire, ntchito ya zingwe zama torque ndikulimbitsa zolumikizira m'malire ovomerezeka. Pachifukwa ichi, opanga magawo, zida zamagetsi ndi zinthu zina, amapereka mafotokozedwe aluso pazogulitsa zawo. Komwe zofunikira zonse zokhudzana ndi kulimbitsa mphamvu zafotokozedwa momveka bwino. Miyezoyi imaperekedwa mosiyana ndi mtundu uliwonse wazinthu. Za hardware, mtundu ndi kapangidwe kazitsulo, kutentha kwake ndi mankhwala, kutentha, zokutira, ndi zina zambiri zimaganiziridwa.

 

Kodi zingwe zopangira torque zimagwiritsidwa ntchito kuti

 

Zida zamanja ndizofunikira pantchito yamagalimoto, makampani opepuka komanso olemera, zomangamanga ndi zamagetsi. Zingwe zomwe zili ndi ma dynamometer zilibe cholinga chenicheni. Kwenikweni pamunda uliwonse wa zochitika pali zofunikira pakuwongolera zolondola za zolimbitsa. Kungoti si akatswiri onse omwe amatsatira malingaliro a opanga. Mu ntchito yomweyo yamagalimoto, mukamagwira ntchito yama tayala, muyenera kumangitsa mawilo ndi wrench ya torque. Kungoti sikuti aliyense amachita izi kutengera luso lake lakuntchito.

Makokedwe amakokedwe amagwiritsidwa ntchito mwakhama pamakina opanga makina ndi mafakitale, komwe ma hardware nthawi zambiri amaphatikizidwa ndi matabwa kapena pulasitiki. Zikatero, kupitirira makokedwe a nati, bolt kapena screw zitha kuwononga maziko. Ndipo ngati simulimbikira, ndiye kuti nyumbayo imamasulidwa ndikutha. Zikatero, chida champhamvu chimathandizira.

 

Kodi mawotchi amakoka ndi chiyani?

 

Msika wapadziko lonse lapansi umapindulitsa, koma mitundu yazida zam'manja siziwala ndi kuchuluka. Ma wrenches onse ndi ma dynamometers amatha kugawidwa m'magulu awiri oyambira:

• Malire makiyi. Chidachi chili ndi njira yosavuta yomwe mungakhazikitsire malire pamlingo wapadera. Ili pamutu pa kiyi kapena chogwirira. Nthawi yofikira ikakwana, kumveka pitani (phokoso limafanana ndikudula kwa gitala). Makiyi olepheretsa akhoza kukhala ndi zosintha zingapo kuti mugwiritse ntchito mosavuta.
• Makina ochezera. Analog (pointer) kapena digito (yokhala ndi LCD) wrench, panthawi yolimbitsa, ikuwonetsa makokedwe apano. Izi ndizosavuta kugwira ntchito pafupipafupi ndi chida, pomwe mumayenera kugwira ntchito ndi zomangira zosiyanasiyana komanso pafupipafupi. Makiyi oterewa ali m'gulu lazida zoyezera, chifukwa zimapereka chidziwitso chowonjezera kwa wosoka.

 

Magwiridwe antchito a torque amafutukuka ndikusintha kosinthasintha ndi mapangidwe a dynamometer pazinthu zina. Chidacho chimatha kusiyanasiyana ndi kukula kwa malo omwe amafikira. Chodziwika ndichakuti maubwino a chidacho ndi zero ngati zitsulo zosinthika sizikupezeka. Chifukwa chake, fungulo limafanana ndi zomwe zilipo. Kapena, imagulidwa yokwanira ndi mitu yomweyi.

Pali mfundo imodzi yomwe wogula ayenera kumvetsera. Palibe zingwe zakuthambo zapadziko lonse lapansi. Makiyi onse ali ndi malire awo osachepera komanso malire. Mwachitsanzo, ntchito yolondola, wrench yokhala ndi malire a 0-25 Nm imagwiritsidwa ntchito. Ndipo magalimoto amatumizidwa m'malo opangira zida ndi chida cha 300-1500 Nm.

 

Ndi torque ziti zomwe zili bwino kugula - mtundu, dziko lochokera

 

Chodziwika bwino cha zida zonse zamanja ndikuti zimapangidwa makamaka ku China kapena Taiwan. Pali kusiyanasiyana mwa mayankho aku America, Britain kapena Germany, koma gawo lawo lonse pamsika silidutsa 1%.

Mafakitale aku China ndi aku Taiwan akhoza kukhala amtundu wakomweko komanso aku Europe (Asia, American). Mtundu uliwonse uli ndi mfundo zake pakupanga ndikugulitsa zida zamanja:

 

• Mapangidwe apamwamba. Zikalata zilibe kanthu. Chidachi chimagwiritsidwa ntchito pazovuta. Makiyi adapangidwa kuti azisamalira mosavomerezeka komanso katundu wambiri. Chida chotere chimapangidwa ndi King King, JONNESWAY, Ega Master, Gedore.
• Mtengo wotsika wa chida. Mtengo wotsika umatengera kuti zida zonse zopangira ma torque zimapangidwa kuti zizidziwike. Chidachi chiyenera kugwiritsidwa ntchito pazolinga zake komanso malinga ndi luso lakudziwika. Mwachitsanzo, ngati katundu wapitilira kapena wagwiritsidwa ntchito molakwika, chidacho chimathyoledwa. Izi zikuphatikiza zopangidwa zonse zaku China zomwe zogulitsa zawo zitha kupezeka mgawo la bajeti. Chidacho chimapangidwa ndi mtundu wapamwamba, koma muyenera kugwira nawo ntchito mosamala.
