Magudumu am'manja amagwiritsidwa ntchito kwambiri pazida zamafakitale ndi zapagulu. Kugwiritsiridwa ntchito kwawo moyenera ndikofunikira pakugwira ntchito kotetezeka komanso kukonza bwino kwa zida. Nkhaniyi ikuwunika masitepe ogwirira ntchito, zochitika zogwiritsira ntchito, kukonza chitetezo, ndi zina zotero, ndikuphatikiza deta yeniyeni kuti ipereke malangizo othandiza kwa akatswiri.

Basic process of handwheel operation
(I) Kapangidwe ka magudumu am'manja ndi mfundo
Gudumu lamanja limapangidwa ndi wheel disc, speaker ndi manja olumikizira. Zimadalira mfundo ya lever kuti atembenuke ogwira ntchito kukhala torque yozungulira kuyendetsa chipangizocho. Kukula kwa chimbale cha gudumu ndi zinthu zimakhudza momwe ntchitoyo ikuyendera. Mwachitsanzo, handwheel yachitsulo yokhala ndi m'mimba mwake ya 200mm imatha kuchepetsa mphamvu yogwira ntchito ndi 30% poyerekeza ndi 150mm chitsanzo; anti-mapangidwe otsetsereka pamtunda amatha kukulitsa kukangana ndi 25% kuti ntchitoyo ikhale yokhazikika.
(II) Njira zoyendetsera ntchito
-kuyang'anirani kagwiritsidwe ntchito: Musanagwiritse ntchito, ndikofunikira kutsimikizira kuti gudumu la m'manja ndi zolumikizira sizili zomasuka kapena zopunduka, ndipo pamwamba pake ndi oyera komanso opanda mafuta. Malinga ndi ziwerengero zamakampani, 80% ya kulephera kwa magudumu am'manja kumachitika chifukwa cha kulumikizana kotayirira. Kuyang'ana kokhazikika kumatha kuchepetsa chiwopsezo cha kutha kwa zida ndi 40%.
Kuyamba kugwira ntchito: Tsatirani mfundo ya "kutseka koloko ndi koloko kuti mutsegule" ndikutembenuza gudumu lamanja mwachangu. Kafukufuku wasonyeza kuti kuthamanga kosalekeza kumatha kukulitsa moyo wautumiki wa wheel wheel ndi 20% ndikupewa kuwonongeka kwamagulu chifukwa cha torque yayikulu nthawi yomweyo.
Kuyika ndi kutseka: Mukafika pomwe mukufuna, mawilo ena am'manja amayenera kukhazikika ndi zikhomo kapena mtedza wokhoma. Zambiri zochokera kufakitale yamankhwala zidawonetsa kuti mutagwiritsa ntchito chotsekera, kuchuluka kwa zolakwika za zida kudatsika kuchoka pa 15% mpaka 5%.
Handwheel ntchito muzochitika zosiyanasiyana
(I) Mfundo zazikuluzikulu zogwirira ntchito m'mafakitale
M'makampani a petrochemical ndi magetsi, mawilo amanja amagwiritsidwa ntchito nthawi zambiri kutseka-mavavu ndi ma valve owongolera mwadzidzidzi. Potengera 300mm m'mimba mwake-chitsanzo cha gudumu la m'manja, mphamvu yogwiritsira ntchito iyenera kuyendetsedwa pa 50-80N・m. -Kugwira ntchito mopitirira muyeso kudzachulukitsa chiwopsezo cha kutayikira kwa ma valve ndi nthawi zinayi. Magudumu onyamula zitsulo zolemera amagwiritsidwa ntchito nthawi zambiri pazochitika zoterezi, zomwe zimakhala zosavala komanso zimatha kupirira kuthamanga kwambiri. .
(II) Makhalidwe ogwiritsira ntchito malo a boma
Zochitika za anthu wamba monga zoperekera madzi ndi ngalande ndi kukonza ma elevator zimayang'ana kwambiri kusavuta kwa ntchitoyo. Mwachitsanzo, chowongolera chozimitsa moto chimagwiritsa ntchito madigiri 90 mwachangu-mapangidwe otsegula, omwe amatha kutsegulidwa ndi kutsekedwa mkati mwa masekondi atatu; mphamvu yogwiritsira ntchito gudumu la pulasitiki lopepuka ndi 10-20N ・ m, yomwe ndiyosavuta kukonza tsiku lililonse.
| Zochitika zantchito | Mtundu wamagudumu am'manja | Mphamvu zogwirira ntchito (N ・ m) | Nthawi yeniyeni yogwirira ntchito |
| Ma valve a petrochemical | Heavy duty metal handwheel | 50 - 80 | 15 - 30 mphindikati |
| Mapaipi operekera madzi ndi ngalande | Wopepuka ntchito pulasitiki handwheel | October 20 | 5 - 10 mphindikati |
| Kudula{0}}kwadzidzidzi chifukwa chozimitsa moto | Mwachangu-kutulutsa m'manja | 30 - 50 | 3 - 5 mphindikati |
Chitetezo ndi kukonza mawilo amanja
(I) Zokhudza chitetezo cha ntchito
Mukamagwiritsa ntchito-wilo lamanja lothamanga kwambiri, ndikoletsedwa kuvala magolovesi kuti mupewe ngozi. Ziwerengero zikuwonetsa kuti 60% ya ngozi zovulala m'manja zimachitika chifukwa chovala magolovesi osaloledwa. Pogwira ntchito pamtunda, zingwe zotetezera ziyenera kugwiritsidwa ntchito kuonetsetsa chitetezo cha ogwira ntchito.
(II) Kusamalira nthawi zonse
Ndikofunikira kuyang'ana kavalidwe ndi kulimba kwa gudumu lamanja kotala lililonse ndikulipaka mafuta chaka chilichonse. Deta yochokera kufakitale yachitsulo ikuwonetsa kuti kukonza kokhazikika kumatha kukulitsa moyo wautumiki wa wheel wheel kuchokera zaka 5 mpaka zaka 8, ndikuchepetsa mtengo wosinthira zida.
Ndi chitukuko cha nzeru zamakampani, mawilo amanja amatha kuphatikizira masensa a kuthamanga, kuyang'anira torque ndi ntchito zina mtsogolomo kuti akwaniritse zenizeni-ndemanga za nthawi yeniyeni ya data yogwira ntchito ndi chenjezo lolakwika, kupititsa patsogolo chitetezo ndi luntha la kuwongolera zida. Kudziwa bwino njira zogwiritsira ntchito ndi kukonza mawilo amanja ndikofunikira kwambiri pakuwonetsetsa kuti zida zikugwira ntchito mokhazikika komanso kuchepetsa zoopsa zachitetezo.
