Kulemba zizindikiro za makina ochapira athyathyathya

"Kodi makina ochapira zovala a flatwater ayenera kulembedwa chizindikiro?" "Ayi?"

“Kodi akufunikira?"……

Lero tikukambirana nkhaniyi nanu, mwina anthu ambiri mumakampani angaganize choncho.“Xiaowan ah, ndiwe wopanda ntchito pang'ono ……".

Monga tonse tikudziwa, mawaya osalala monga cholumikizira chofunikira kwambiri, makamaka amatenga gawo pakuwonjezera malo olumikizirana, ndikufalitsa udindo wa kupsinjika kwa kukhudzana. Mawaya ambiri osalala omwe amagwiritsidwa ntchito popanga mafakitale alibe chizindikiro chofanana ndi chomwe chili pachithunzichi pansipa.

Ndiye ndi zochitika ziti pamene makina ochapira a flatwater adzalembedwa chizindikiro?

(1) Chomera chopangira zinthu kuti chisasakanize zinthu

Ma washer a flat pakupanga njira yopapatiza yopondaponda, malo opangira makina ...“304"pachithunzi chotsatirachi, ndiko kuti, m'malo mwa chotsukira chathyathyathya pali zinthu za A2. Ngati wopanga apanga chotsukira chathyathyathya cha zinthu zomwezo mu zinthu za 316 nthawi imodzi, ndiye kuti chotsukiracho chikhoza kulembedwa ndi“316"or “A4".

Chizindikiro ichi cha kuzindikiritsa zinthu ndi chofala kwambiri mu makina ochapira achitsulo chosapanga dzimbiri, chifukwa chake ndi chakuti pambuyo pa kupanga zinthu zachitsulo chosapanga dzimbiri nthawi zambiri zimachitika pokhapokha mutatsuka ndi kuyeretsa, kuchokera ku mawonekedwe oyera owala, sangathe kusiyanitsa mwachilengedwe zinthu zake.

Zinthuzo zili bwino pamwamba pa makina ochapira achitsulo chosapanga dzimbiri omwe amatha kupewa kupanga kapena kusonkhanitsa zinthu zosakaniza.

(2) malamulo okhazikika

Miyezo ina ya malonda imalongosola zofunikira za makina ochapira osalala omwe ali ndi chizindikiro, mwachitsanzo, muyezo“EN", “EN", “EN", “EN", “EN"ndi“EN".

Mwachitsanzo, muyezo“EN 14399-5 (GB / T 32076.5) Zolumikizira zomangira zolimba kwambiri zodzaza kale Gawo 5: Ma washer athyathyathya"Mu makina ochapira ozizimitsidwa komanso otenthedwa bwino, makina ochapira ayenera kukhala ndi chizindikiro chopindika, monga momwe tawonetsera pansipa:

Mwachitsanzo, muyezo“Makina Otsukira a Chitsulo Olimba a ASTM F436"imanena kuti makina ochapira athyathyathya omwe ali pansi pa muyezo uwu ayenera kukhala ndi chizindikiro cha“F436"chizindikiro, monga momwe zasonyezedwera pansipa:

Kodi makina ochapira a flatwater olembedwa kapena osalembedwa ndi muyezo angakhazikitsidwe pati?

Poyang'ana miyezo ya malonda yomwe ilipo, miyezo ya makina ochapira athyathyathya ngati ayenera kuyika chizindikiro sichinafotokozedwe bwino.

Muyezo wa ISO 898-3:2018 (kapangidwe ka makina a zomangira - ma washer athyathyathya) Muyezowu ndi kukhazikitsa zofunikira pakugwira ntchito kwa ma washer athyathyathya achitsulo cha kaboni, zitsulo za alloy mu 2018, pomwe mutu 9.2 wa chizindikiro cha washer wathyathyathya unafotokoza momveka bwino.

Chizindikiro cha makina ochapira chathyathyathya chikhoza kukhala chogwirizana ndi wopanga kapena ndi mgwirizano pakati pa kupereka ndi kufunikira.

Mawacha osalala sayenera kulembedwa ndi zilembo zokwezedwa. Kuyika chizindikiro cha concave nthawi zambiri sikuvomerezeka chifukwa kungasinthe ubale wa mphamvu ya torque-clamping ya bolt-nut joint kapena kupanga kupsinjika komwe kungayambitse kusweka kwa washer.

Mfundo ziwiri zomwe zili pamwambapa zikusonyeza kuti kuyika chizindikiro pa makina ochapira a flat sikofunikira, ndipo ndi udindo wa wogulitsa kusankha kapena kukambirana ngati kuyika chizindikiro kukufunika musanayitanitse. Sikoyenera kuyika chizindikiro pamwamba pa makina ochapira a flat ndi zilembo zojambulidwa kapena zopindika.

Chotsukira chachitsulo chosapanga dzimbiri cha Austenitic, pamwamba pake pali chokhotakhota, chimasintha mphamvu yolumikizira bolt - nati - mgwirizano wa mphamvu yolumikizira uyenera kutsimikiziridwa, ndikotsimikizika kuti, chifukwa cha kuuma kochepa kwa chitsulo chosapanga dzimbiri cha austenitic, chotsukira cha concave sichidzapangitsa kuti makina ochapira akhale ndi nkhawa, sichidzayambitsa ming'alu ya chotsukira.
