chosankha: Chipinda chopumulira mkono chimakhala chotentha kwambiri panthawi yogwira ntchito
1. Kupsinjika kwachogwirirandi yothina kwambiri kapena yomasuka kwambiri kapena bala lotsogolera latsekedwa;
2. Mawonekedwe a chipangizo chowongolera si osalala, ndipo chipangizo chowongolera sichili pamzere wopingasa womwewo;
3. Mphamvu yokankhana ya gudumu loyendetsa la chogwirira ndi yolimba kwambiri kapena yomasuka kwambiri, ndipo gudumu loyendetsa silili pakati pa chogwirira;
4. Chipangizo chosinthira cholowera m'manja chatha.
Ngati mavuto omwe ali pamwambawa athetsedwa, malungo adzachepa. Chogwiriracho chimayendetsedwa ndi mphamvu yokangana, kotero padzakhala kutentha pang'ono.
Funso: Chogwiriracho chimagwa panthawi yogwira ntchito
1. Chitsanzo cha chogwirira cha mkono ndi cholakwika, mlomo ndi waukulu kwambiri, womwe sukwaniritsa zofunikira, kapena rabara imataya ntchito yake itatha kugwiritsidwa ntchito kwa nthawi yayitali. Pakadali pano, chogwirira cha mkono chiyenera kusinthidwa;
2. Chogwirira chimatambasulidwa pang'onopang'ono mukachigwiritsa ntchito kwa nthawi yayitali, ndipo chogwiriracho chiyenera kumangidwanso panthawiyi;
3. Mapiko a gudumu lokangana ndi ofooka komanso omasuka, ndipo amafunika kusinthidwa;
4. Gudumu la lamba wopanikizika latha ntchito ndipo lamasuka.
Kugwira ntchito kwa handrail kumadalira kuphatikiza kwa zowonjezera zingapo, ndipo zifukwa zogwera zitha kufufuzidwa chimodzi ndi chimodzi.
Funso: Chingwe chotsetsereka cha chogwirira chatha ndipo waya wachitsulo wawonekera
1. Pali ming'alu pamwamba pa gudumu lopiringizika, zomwe n'zosavuta kuwononga gawo lotsetsereka la chogwiriracho kudzera mu friction;
2. Gudumu lokangana ndi gudumu la lamba wokakamiza si njira yofulumizitsira zinthu, zomwe n'zosavuta kuwononga pamwamba ndi gawo lotsetsereka la chogwiriracho;
3. Gulu la ma sprocket ozungulira lawonongeka. Pa arc ya lamba wogwirizira, gulu la ma sprocket ozungulira silizungulira. Gawo lotsetsereka limakanda kwa nthawi yayitali, ndipo lamba wogwirizira amakhala ndi mwayi wowonongeka, choncho ndikofunikira kwambiri kusankha unyolo wozungulira;
4. Kuchuluka kwa kugwedezeka kwa zinthu zomwe zili mu gawo lotsetsereka la chogwirira sikokwanira, zomwe zimapangitsa kuti gudumu lotsetsereka ndi chogwiriracho ziterereke ndi kutentha, ndikuwononga gawo lotsetsereka.
Funso: Pamwamba pa chogwirira cha mkono pali mikwingwirima, mizere, komanso kuwonongeka kwakukulu
1. Chingwe cha gudumu la lamba wopanikizika chawonongeka, mawonekedwe ozungulira ndi osiyana, kapena sazungulira, ndipo chimakhudza mwachindunji ndi lamba wogwirizira, zomwe zimapangitsa kuti pamwamba pakhale kusweka;
2. Khomo lolowera ndi kutuluka kwa escalator lawonongeka. Ma escalator ena amagwiritsa ntchito khomo ndi kutuluka ndi tsitsi. Tsitsi likukalamba ndipo silingasinthidwe pakapita nthawi. Ma escalator ena amagwiritsa ntchito khomo ndi kutuluka popanda tsitsi.
3. Chifukwa cha zinthu zakunja, ngati pali kukangana pakhomo ndi potulukira, pamwamba pa chogwiriracho chidzawonongeka.
Funso: Mlomo wa chogwirira cha mkono wawonongeka ndipo wasweka
1. Kuwonongeka kwa mlomo wa chogwirira cha mkono kumachitika chifukwa cha kugwira ntchito kosalekeza kwa chogwirira cha mkono ndi kukangana ndi zowonjezera zina kwa nthawi yayitali;
2. Chochitika chovutachi chiyenera kuchotsedwa, chomwe chambiri chimachitika chifukwa cha minga yomwe imalumikizidwa ndi malo olumikizirana njanji zowongolera;
3. Mlomo wa chopumulira mkono ndi waukulu kwambiri ndipo umagwedezeka kumbuyo ndi kumbuyo, zomwe zimapangitsa kuti mlomowo uwonongeke.
Funso: Matuza amawonekera pamwamba pa chogwirira cha mkono
1. Chigawo chosatha cha handrail sichimaphatikizidwa bwino, zomwe zimapangitsa kuti pakhale kugawanika ndi kutumphuka. Chifukwa chake n'chakuti palibe kukanikizana panthawi yopanga ndipo mpweya sunachotsedwe;
2. Kupanikizika sikufanana pamene chogwirira cha mkono chatenthedwa ndi kutentha ndi kutenthedwa, zomwe zimapangitsa kuti mpweya usachotsedwe;
3. Malo otenthetsera sali ofanana panthawi ya thermosetting vulcanization, zomwe zimayambitsa vuto la stratification;
4. Kuoneka kwa ma vesicles panthawi yogwiritsidwa ntchito kumachitika chifukwa cha kuipitsidwa kwa mafuta pamwamba, zomwe zimapangitsa kuti zinthu za rabara zisinthe;
5. Chogwirira choyendetsedwa ndi dongosolo lolunjika chimakhala chotentha kwambiri ndipo chimayambitsa kusweka kwa rabara ndi thovu.
Kapangidwe ka chogwirira ntchito kamatsimikizira zolakwika za chogwirira ntchito. Chogwirira ntchito ndi kuphatikiza kogwira mtima kwa rabara ndi chingwe. Chifukwa cha thermosetting vulcanization, sichingasinthe kapangidwe ka molekyulu ya chingwe, kotero sichingapange chinthu chonse chosagwirizana. Payenera kukhala mpweya wobisika m'malo obisika, kotero makampani opanga zogwirira ntchito padziko lonse lapansi sanagonjetse chinthu chopangira thovu cha chogwirira ntchito, ndipo wopanga aliyense akuyesera kuchepetsa vuto la thovu.
Funso: Pamwamba pa chogwirira cha mkono pali ming'alu
Zolakwika, ming'alu, ndi mikwingwirima zimawonekera pamwamba pa handrail, zomwe zimatchedwa ming'alu pa handrail. Chifukwa chachikulu cha ming'aluyi ndi
Rabala yogwira m'manja imakalamba, chifukwa cha kutentha, mpweya, kuwala, mphamvu ya makina, kuwala, mankhwala, mpweya.
Zotsatira za zinthu zakunja monga ozone zimayambitsa kusintha kwa mankhwala mu unyolo wake waukulu, kuwononga kapangidwe ka mankhwala koyambirira ka mphira,
Zotsatira zake, ntchito ya rabara imachepa.
