Sisitemu yo guhingura asifalti itanga inyungu zishobora kugaragara mu iyubakwa ry’imihanda, gukoresha ingufu za peteroli, hamwe n’ibisohoka - cyane cyane iyo bikozwe mu mishinga minini yo hagati y’imijyi minini n’intara mu majyepfo y’iburasirazuba bwa Aziya na Afurika. Twabibonye ubwacu: icyiciro cya 2023 cy’ibiti bya asifalti byashyizwe hafi y’Umujyi wa Ho Chi Minh byagabanije ubukonje buvanze ubukonje ku kigero cya 42% mu gihe cy’amezi atandatu, bitatewe n’ibisabwa ku isoko, ahubwo ni ukubera ko logique yo kugenzura yatwitse ihuye n’isi yose hamwe n’ubushuhe. Ngiyo itandukaniro riri hagati yimpapuro zerekana nibikorwa byerekanwe.
Kuki "Bikora" Bisobanura Kurenza Ibisohoka Tonnes gusa
Abaguzi benshi bashimangira ubushobozi bwizina - “320 TPH” byumvikana neza kugeza bamenye ko igice gihagaze kuri 210 TPH mugihe cyimvura. Imikorere nyayo ituruka mubice bitatu bifatanye: ituze ryumuriro, ibintu bitamenyekana neza, hamwe ninshingano yo gutabaza. Uruganda rwa Speco asfalt rubigeraho binyuze mubyiciro bibiri byumye byumye hamwe nibiryo byihuta byihuta, ibyuma bifata ibyuma bifata ibyokurya bigaburira igihe cyo gutwika, hamwe no kugarura umukungugu wa modula bikomeza umuvuduko ukabije muri ± 3% mugihe cyamasaha 8-12. Twagerageje Unit SP-240B i Yunnan iminsi 17 ikurikiranye munsi yubushyuhe bwa 92% - kandi twabonye ihagarikwa rimwe gusa ritateganijwe, ryatewe nihindagurika ryingufu zituruka hanze, ntabwo byananiranye imbere.
Icy'ingenzi, ibihingwa bya Speco birinda "umutego wubushobozi" bikunze kugaragara mubice byingengo yimari: gutwika cyane bifatanije nabafana badafite ingufu. Uku kudahuza guhatira abashoramari gukuramo ubushyuhe bwintoki, bigatuma ubushyuhe bwiyongera mubuvange bwa nyuma. Igishushanyo cya Speco gikoresha ibipimo bihuye nabafana-gutwika (urugero, 1.850 m³ / h yumuyaga mwuka wa megawati 1,2 MW) byemejwe na EN 13108-1 ibisabwa byubushuhe. Igisubizo? 98.3% by'icyitegererezo cyujuje ± 5 ° C kwihanganira gusohoka - nta gikorwa gikenewe ku rubuga.
Kwiyubaka Ntabwo Gucomeka-no-Gukina-Dore Ibyo Ukeneye Mubyukuri
Amakipe amwe akeka ko uruganda rwa Speco asifalt rugeze nka skid imwe hanyuma rugatangira gutanga umusaruro mumasaha 72. Ukuri gusaba ishingiro ryukuri. Ubwa mbere, ubujyakuzimu bugomba kurenga metero 1.8 mu butaka bukungahaye ku ibumba - itsinda ryacu ryapimye umuvuduko wo gutura wa mm 4,7 / ukwezi ku kibanza gito muri Tanzaniya, bituma buri minsi 11 yimurwa. Icya kabiri, gutanga amashanyarazi bisaba 400V ± 2% bihamye, ntabwo "imbaraga zibyiciro bitatu." Umuvuduko ukabije uri munsi ya 385V wateje impuruza 12 zitari zo kuri PLC mumushinga uherutse muri Bangladesh. Icya gatatu, umuhanda winjira ukenera toni 12 yumutwaro wikigereranyo - ntabwo ari ubugari gusa - kugirango utange ibice; module ishyushye module yonyine ipima toni 9,6.
Ubu dushyiramo urutonde-rwiteguye kurutonde hamwe na buri cote. Ibi bitwikiriye ibizamini byo guhuza ubutaka (CBR ≥95%), imipaka ya transfert (metero 45 uvuye kumwanya munini), hamwe no gushushanya urusaku rwibidukikije (kugirango ucecekeshe kure yimidugudu iri hafi). Gusimbuka intambwe iyo ari yo yose byongera iminsi 11–19 kuri komisiyo. Umukiriya umwe yazigamye $ 210.000 mugiciro cyabakozi badafite akazi mukoresha urutonde rwacu mbere yo gusuka beto.
Igiciro cyo Gukora Ntabwo ari lisansi gusa-Ni Igihe cyo Kuruhuka, Umurimo, na Spare
Gukoresha lisansi bifite akamaro-ariko ni 37% gusa yikiguzi cyo gukora mugihe cyimyaka 5 yubuzima. Ingano nini ni ukubungabunga amasaha yakazi, igice-cyigihe cyo kuyobora, hamwe no guhagarara bidateganijwe. Ibishushanyo mbonera bya Speco asfalt bigabanya uko ari bitatu. Kurugero, ingoma yingoma ikoresha moteri itaziguye aho gukoresha urunigi-na-sisitemu. Ibi bikuraho igenzura rya buri cyumweru, ingingo zamavuta, hamwe no gusimbuza urunigi buri masaha 4.200. Mubikorwa, imirimo yo kubungabunga yagabanutse kuva 18.5 igera kumasaha 6.2 / icyumweru mugushiraho 2022 Sri Lanka.
- Kwambara imyenda ikoresha ibyuma bya AR400 hamwe nibice bisimburwa - ntabwo bisimbuza ingoma yuzuye
- Igenzura ryibikoresho byoherejwe na interineti yo kwisuzumisha: abatekinisiye bamenya amakosa ya sensor badahuza na seriveri
- Ibikoresho bisanzwe (burner nozzles, inteko ya thermocouple, imikandara ya convoyeur) ibigega byaho mubihugu 14 - harimo Nigeriya, Vietnam, na Peru
Ibi ntabwo ari amahame. Iyo thermocouple yananiwe saa tatu za mugitondo mu ijoro rikomeye ryasutswe muri Oman, itsinda ryurubuga ryarisimbuye mu minota 22 bakoresheje ibice bivuye mu bikoresho byabo - nta gutegereza ibicuruzwa byo mu kirere. Nibyo kwihanganira ibikorwa byubatswe mubyuma, ntabwo byasezeranijwe mumasezerano ya serivisi.
Kureba imbere: Kwishyira hamwe, Ntabwo Kwigunga
Umupaka ukurikira ntabwo ari ibihingwa binini-ni uguhuza ubwenge. Abashinzwe kugenzura ibihingwa bya Speco ubu bashyigikiye protocole ya Modbus TCP na OPC UA bivuye mu gasanduku, bigafasha gutanga amakuru mu buryo butaziguye kuri sisitemu yo gucunga pavement nka Pavement Management Information System (PMIS) cyangwa Autodesk BIM 360. Turimo kubona abashoramari bahuza ibiti by’ubushyuhe bwa asfalt hamwe n’ibisubizo by’ibizamini bya nyuma nyuma y’amezi 18 yo hejuru. Ubwo bushishozi buhindura uburyo bahindura ibishushanyo mbonera.
Taian Yueshou Mixing Equipment Co., Ltd., ifite icyicaro i Taian, Intara ya Shandong, mu Bushinwa, yatunganije ubwo buryo kuva mu myaka ya za 90. Hamwe n'abakozi barenga 1200 hamwe na metero kare 110.000 z'ahantu ho gukorerwa, bashyira imbere ibitekerezo byumurima kuruta ibipimo bya laboratoire - nko kongeramo ruswa idashobora kwangirika kwangirika kwimbere nyuma ya raporo zagiye zivugwa ko zatewe na chloride zatewe mu mishinga yo ku nkombe. Umurongo wabo wa spo asfalt ugaragaza icyakora - ntabwo ari cyiza ku gatabo.
Gukora neza mumihanda ntabwo ari uguhiga umubare wimpera. Nijyanye no gukuraho ubushyamirane: hagati yikirere n’ibisohoka, hagati yimpapuro zidasanzwe nubutaka bwubutaka, hagati yo kubungabunga no kwambara nyabyo. Speco asfalt yibihingwa byerekana ko iyo injeniyeri yubaha ukuri-atari ibitekerezo gusa-umuhanda wubatswe vuba, ukomeye, kandi uhendutse. Tangira ibintu uhura nabyo - ntabwo ari ubushobozi wizeye.
