Mphamvu ya coke ndi nsalu mfundo kuwonjezeka

Mphamvu ndi minofu Cox compensators Mu mphamvu coke zikutanthauza umatha kupirira katundu osiyanasiyana zowononga (mantha, kumva kuwawa) imene ili pansi pa zoyendera wolunjika, ndiponso kudyetsa m'ng'anjo yamoto pa yadothi. Mundawu akuti ndi ofunika kwambiri chizindikiro cha khalidwe la coke. Kodi kupanga cholimba ndalama coke chimathandiza kukhalabe mkulu mpweya permeability ya mtengo ndi zokolola mkulu wa kuphulika ng'anjo. mphamvu coke anatsimikiza ndi kusokonezeka yokumba zitsanzo poyera kuti amadza ndi katundu abrasive. Kuyeza mphamvu kusintha sieve (tinthu kukula) wa zikuchokera kwa coke pa kudziyesa komanso kugwiritsa ntchito mfundo nsalu kukula. The njira Ambiri ntchito adziwe coke mphamvu kuswa mu ng'oma onsewo. Njira imeneyi imakhala chakuti coke ena kukula chitsanzo cha kukula ena aikidwa mkati ng'oma, pambuyo umene zimayenda pa liwiro anakonzeratu nthawi anakonzeratu. Chunks a coke entrained oposa kugwa, ndipo anatsanulira, motero kupeza kachigawo ng'oma ndi katundu abrasive anawonongedwa amakhala osiyana modalira mphamvu zawo mawotchi. Mphamvu amakhala ndi kusintha kukula zidutswa coke chifukwa cha mayeso. Mu dziko lathu izo kalekale njira muyezo kudziwa mphamvu ya coke ng'oma akufuna mu Russia mu mochedwa chakhumi ndi chisanu ndi chinayi atumwi E.Sundgrenom. Drum 2,000 mm m'mimba mwake ndi 800 mm m'lifupi ali pamwamba cylindrical mu mawonekedwe a latisi ndodo ya m'mimba mwake 25 mamilimita ndi yemweyo kumatanthauza therebetween compensators. Ng'oma ndi yodzaza coke chitsanzo kulemera kwa makilogalamu 410 zidutswa 25 mm. ng'oma ndi zimayenda kwa mphindi 15 pa 10 Rev / min. Chiwonongeko chifukwa cha tating'ono ting'ono coke kugwa kudzera mipata pakati pa ndodo. Mphamvu chizindikiro ndi unyinji wa coke otsala mkati ng'oma ndi. Mbali zina ndi kuchuluka kwa 10-0 mamilimita kachigawo podbarabannom mankhwala. Yaitali zochitika zasonyeza kuti ntchito yachibadwa ya kuphulika ng'anjo kungakhale coke, kupereka mpumulo wa ng'oma si makilogalamu zosakwana 300. The mitundu bwino ndi 340-350 makilogalamu ng'oma nyemba. Similar njira ya kuyesedwa nsalu kuwonjezeka mafupa ntchito m'mayiko ambiri Komabe, ng'oma kukula, kulemera kwa chitsanzo, chiwerengero cha kusintha zosiyana. Chifukwa cha kupanda comparability zizindikiro za mphamvu coke ndi ntchito pa ng'anjo awo kuphulika. Choncho, mu 1963 Soviet Sundgren anafotokoza njira m'malo ndi njira lonse kudziwa mphamvu ya coke kakang'ono chatsekedwa ng'oma m'mimba mwake ndi mamilimita 1,000 m'litali (GOST 8929-65). Padziko lamkati la ng'oma 4 ndi welded m'mabokosi 100 mm. Kuyesa chitsanzo coke mlandu akuluakulu 60 mm ndi kuchuluka kwa makilogalamu 150, limene mbali 3 ndi kulemera kwa makilogalamu 50. ng'oma ndi mlandu wina mbali iyi (50 kg) ndipo amayambitsa atembenuza pa liwiro la 25 Rev / Mph kwa mphindi 4. Chitsanzo anali ndiye amachotsedwa ndi kuwanditsa sieve ndi mabowo wozungulira awiri 40 mamilimita ndi 10 mm. Yodziwika zokolola mphamvu coke kachigawo 40 mm (kuzilingalira M40), ndiponso abradability - zokolola kachigawo 10-0 mm (M10 chigawo) mu kuchuluka kwa kulemera kwa chitsanzo. Kokayezetsa zitsanzo ziwiri. Mu nkhani ya zotsatira zikusiyana mawu a M40 ndi oposa 3% mu mawu oposa 1% M10 lachitatu mayeso nyemba. The chifukwa yomaliza mtima pafupifupi masamu. The apamwamba a M40 ndi M10 pansipa, mphamvu za coke. M'zaka zaposachedwapa, pa ambiri mafakitale coke mphamvu mayeso omwewo (zing'onozing'ono) ng'oma (GOST 5953-72), nthawi yomweyo chifukwa otsitsira ndi kasinthasintha, koma kutenga mayeso coke tirigu kukula 25 mm. Mphamvu index la coke zipatso ndi 25 mamilimita kachigawo (M25) ndi abradability - M10. The zikutanthauza mtengo wa zolozerazi mphamvu coke, pa USSR 1985 zomera South zosiyanasiyana mu ranges zotsatirazi: M25 - kuchokera 70,7 kuti 88,9%; M10 - kuchokera 6.3 kuti 11,3%, ndi mafakitale a Russia ndi Kazakhstan: M40 - kuchokera 57,8 kuti 75,1%; M25 - kuchokera 83,7 kuti 87,6% ndi M10 - kuchokera 6.5 kuti 10,0%. njira Komanso zafotokozedwa kwa kudziwa mphamvu ya kuphulika ng'anjo coke ntchito ndi ena. A sangathe awa njira mayeso coke mphamvu boma ozizira lagona pa mfundo yakuti sangathe amanena mphamvu yake pa kutentha kumene coke ndi mkangano mu kuphulika ng'anjo. akufuna kukhazikitsa njira kuti tipeze mtendere matenthedwe la coke lapansi. coke mphamvu kwambiri zimadalira kuchuluka ndi mtundu Ming'alu chunks ake. Chiwonongeko kumachitika mwa zidutswa fractures, amaika nkhawa mkati akuwuka pa coking. Research wasonyeza kuti kusintha mu yogawa tinthu kukula kwa coke si njila kwa fupa lothyoka mphamvu, choyamba mofulumira wosweka coke, kuchuluka kwa ndalama ukuwonjezeka kwambiri ndipo amachepetsa yokhudza ufiti lalikulu, ndiye kugawikana kubweza. kukula wotsatira wa wovulala amatsogolera makamaka coke kumva kuwawa, chifukwa kuphwanya chidutswa lonse zovuta. Zimenezi zinathandiza kuti asa- coke mphamvu ya okhazikika sieve zikuchokera, analandira pambuyo kukhazikitsa ming'alu onse ndi nkhawa mkati. Kuchotsa coke ku kuphulika ng'anjo mwa tuyere wasonyeza kuti kapangidwe kake limafanana pafupifupi sieve zikuchokera okhazikika. Amadziwika kuti mpweya permeability nsalu mfundo kuwonjezeka kumasula mfundo chimauma ali bwino ndi kuwonjezeka mu homogeneity zidutswa kukula kwake. Kuonjezera pachilichonse za kukula coke kupeza akadakwanitsira kukula chunks kwa ng'anjo kuphulika (25-40 mm) kuyesa Pre-ziziyenda chophimba chake zikuchokera mwa kugonjera kwa wina kuchuluka kwa nkhawa makina, kenako mtundu wa ndalama chifukwa. Izi kuchepetsa unaipiraipira amene apezeka coke kupanga mu kuphulika ndalama ng'anjo ndi kusintha permeability mpweya wa woyang'anira mu mabacteria ake apamwamba kutentha.
