Chiyambi cha Zamalonda
Makina ochapira masika, omwe amadziwikanso kuti ochapira masika, amagwira ntchito yofunika kwambiri pamakina opangira makina ndi zomangira. Nthawi zambiri amagwiritsidwa ntchito kuonjezera malo olumikizana pakati pa zinthu, kupititsa patsogolo kukhazikika, komanso kuchepetsa kuwonongeka kwa mikangano pakati pa zigawo. Ntchito zazikulu za khushoni ndikuletsa kumasula, kuyamwa modzidzimutsa, kupewa kutulutsa mpweya, kukhala ngati chotchinga, komanso kupereka chitetezo m'malo enaake. Zinthu za pad kasupe ndi zosiyanasiyana, kuphatikizapo zitsulo zosapanga dzimbiri ndi carbon zitsulo (kawirikawiri chitsulo), ndipo palinso makulidwe osiyanasiyana kusankha kuchokera, monga M3, M4, M5, M6, M8, M10, M12, M14, M16, etc. The dziko muyezo GB/T 94.1-2008 limatchula mikhalidwe luso khalidwe lawo masika ndi kukhazikika pads.
Zochitika zogwiritsira ntchito ma washers a kasupe ndi otakata, makamaka pamene mphamvu yolimba ya ma bolts siili yokwera ndipo katundu wothamanga ndi wochepa. Pamene mbali yolumikizidwa imakhala yofewa, m'mphepete lakuthwa la makina ochapira kasupe amatha kuikidwa kuti asatuluke. Kuonjezera apo, pamene kutalika kwa bawuti kuli kochepa ndipo kumasuka kwa bawuti kumakhala kofunikira, ngati mphamvu zotanuka za washer sizili zosiyana kwambiri ndi mphamvu yomangirira ya bawuti, wochapira wa masika amatha kubweza mpumulowu. Komabe, mu kugwirizana mkulu-mphamvu bawuti, chifukwa ang'onoang'ono mapeto nkhope ya wochapira kasupe poyerekeza ndi lathyathyathya wacha lathyathyathya, pansi chimodzimodzi chisanadze kumangitsa mphamvu ndi zinthu kunja katundu, zingachititse mapindikidwe padziko mbali, potero kuchepetsa chisanadze kumangitsa mphamvu bawuti ndipo pang'onopang'ono kuchititsa kumasuka. Chifukwa chake, posankha kugwiritsa ntchito makina ochapira masika, ndikofunikira kuganizira mozama momwe mungagwiritsire ntchito komanso mtundu wa bawuti.
Kuphatikiza pa ma washers a masika, palinso mitundu ina ya ma washers monga ma washer ophatikizika ndi anti loosening washer, iliyonse ili ndi mawonekedwe osiyanasiyana ogwiritsira ntchito komanso zabwino zake. Makina ochapira a Flat amagwiritsidwa ntchito makamaka kuteteza ma bolts ndi mtedza, pomwe ma washer oletsa kumasula amakhala ndi mphamvu zoletsa kumasula. Kumvetsetsa mawonekedwe ndi mawonekedwe ogwiritsira ntchito ma gasketswa kungatithandize kusankha mtundu woyenera wa gasket kutengera zosowa zenizeni kuti tiwonetsetse kudalirika komanso chitetezo cha kulumikizana.
Zida zazikulu
Nthawi zambiri, 65MN masika zitsulo kapena 70 # kaboni zitsulo, 3Cr13, zosapanga dzimbiri zipangizo SUS304 kapena SUS316, komanso zipangizo phosphor mkuwa angagwiritsidwe ntchito.
Cholinga chachikulu
Amagwiritsidwa ntchito pansi pa mtedza kuti asamasulidwe.
Zimanenedwa mu miyezo ya dziko.
Njira zopewera mtedza (kapena ma bolts) kuti zisasunthike pamakina ndi kupanga ndi monga:
1. Onjezani zochapira masika; (Zosavuta komanso zosavuta kuchita)
2. Gwiritsani ntchito mtedza wa hexagonal ndi mapini ong'ambika; (Kuwonjezeka kwa chaka ndi chaka pamachitidwe opangira)
3. Onjezani makina ochapira; (Kuwonjezeka kwa chaka ndi chaka pamachitidwe opangira)
4. Ikani waya wachitsulo mu dzenje lamutu la hexagonal la bawuti ya hexagonal. (Kuwonjezeka kwa chaka ndi chaka pamachitidwe opangira)
Makina ochapira masika amagwiritsidwa ntchito poletsa kumasula, monga kuwonjezera zochapira masika kumaboliti olumikiza mota ndi makina oyambira, chifukwa injini ikagwedezeka popanda zotsukira masika, mtedzawo umasweka. Nthawi zambiri, zomangira pazida zokhala ndi vibration zimakhala ndi zochapira masika, pomwe ma flange nthawi zambiri safuna ma washer. Kukhalapo kapena kusakhalapo kwa zotsukira masika pa ma flanges zimagwirizana ndi sing'anga yomwe ikuyenda kudzera mupaipi. Ngati sachedwa kugunda m'badwo, ndi bwino kuwonjezera ochapira masika. Palinso mapaipi amadzimadzi othamanga kwambiri omwe amasinthasintha pafupipafupi m'mimba mwake, kotero musamapangitse zinthu zonse. Pa ma valve ena, ochapira masika amafunikira kuti awonjezedwe pa flange ya chivundikiro cha bokosi lonyamula, ndipo kusankha kwa ma washer a masika kumaphatikizidwa muzosankha za Quick Easy Optimization automation.
Kusiyana kwakukulu
Makina ochapira masika amatha kuchitapo kanthu poletsa kumasula ndikuwonjezera mphamvu yomangitsa, pomwe ma washer ophwathika alibe ntchitoyi. Zitha kugwiritsidwa ntchito kukulitsa malo olumikizirana omangika, kupewa kukangana pakati pa mabawuti ndi zida zogwirira ntchito, kuteteza pamwamba pazigawo zolumikizira kuti zisagwetse malo ogwirira ntchito pomwe ma bolts ndi mtedza zimakhazikika.
Koma maulumikizidwe ena ofunikira, monga omwe amadalira kwambiri kukanikizana kuti apange mikangano ndi kufalitsa mphamvu, sangathe kugwiritsa ntchito mapepala a kasupe. Kuzigwiritsira ntchito kumachepetsa kukhazikika kwa kulumikizana ndipo kungayambitse ngozi. Pamene mphamvu ya chigawo cholumikizidwa ndi chochepa, mawotchi ophwanyika kapena ma flange bolts amagwiritsidwa ntchito kuti awonjezere malo okhudzana. Pakakhala kugwedezeka, kugunda, kapena kusinthasintha kwakukulu kwa kutentha kwapakati, zotsukira masika ziyenera kugwiritsidwa ntchito.
