Speco asphalt cog tshuab xa cov txiaj ntsig ntsuas tau hauv kev tsim kho ceev, roj efficiency, thiab cov khoom tsim tawm-tshwj xeeb tshaj yog thaum siv rau hauv nruab nrab-rau-loj hauv nroog thiab lub xeev txoj kev loj nyob thoob plaws Asia thiab Africa. Peb tau pom qhov no ua ntej: ib pawg 2023 ntawm Speco asphalt cov nroj tsuag tau teeb tsa ze ntawm Ho Chi Minh City txiav lub caij txias-tso qis los ntawm 42% dhau rau lub hlis, tsis yog vim yog kev lag luam thov, tab sis vim tias lub tshuab hluav taws xob tswj kev sib tw ua kom lub ntiaj teb sib xyaw ua ke noo noo. Qhov ntawd yog qhov sib txawv ntawm daim ntawv specs thiab kev ua haujlwm pov thawj.
Vim li cas "Efficient" txhais tau ntau tshaj li qhov tso tawm Tonnes
Ntau tus neeg yuav khoom kho ntawm lub peev xwm nominal - "320 TPH" suab zoo kawg nkaus kom txog thaum lawv paub tias chav tsev nyob ntawm 210 TPH thaum lub caij ua haujlwm monsoon-season. Kev ua tau zoo tiag tiag tshwm sim los ntawm peb txheej txheej sib cuam tshuam: thermal stability, cov ntaub ntawv ntws tau kwv yees, thiab tus neeg teb xov tooj cuam tshuam zaus. Ib tsob nroj Speco asphalt ua tiav qhov no los ntawm ob-theem ziab drums nrog kev sib txawv-ceev feeders, kev sib xyaw cov dej noo sensors noj cov kev hloov pauv ntawm lub sijhawm, thiab cov plua plav rov ua haujlwm uas tswj kev nqus siab hauv ± 3% hla 8-12 teev hloov. Peb tau sim Unit SP-240B hauv Yunnan rau 17 hnub sib law liag hauv qab 92% txheeb ze av noo-thiab pom tsuas yog ib qho kev kaw tsis tau npaj tseg, tshwm sim los ntawm kev hloov pauv hluav taws xob sab nraud, tsis yog sab hauv.
Tseem ceeb heev, Speco nroj tsuag zam qhov "muaj peev xwm cuab" uas muaj nyob rau hauv cov nyiaj txiag-tier units: oversized burners ua ke nrog undersized pa kiv cua. Qhov kev tsis sib haum xeeb no yuam cov neeg ua haujlwm kom thim qhov hluav taws xob tso tawm manually, ua rau kub hnyiab hauv qhov sib tov kawg. Speco tus tsim siv qhov sib npaug ntawm cov kiv cua-kub qhov sib piv (piv txwv li, 1,850 m³ / h airflow ib 1.2 MW thermal output) validated tiv thaiv EN 13108-1 thermal homogeneity yuav tsum. Qhov tshwm sim? 98.3% ntawm cov qauv ua tau raws li ± 5 ° C kam rau ua thaum tso tawm - tsis tas yuav rov ua haujlwm ntawm qhov chaw.
Installation Tsis Plug-and-Play - Nov yog yam koj xav tau tiag tiag
Qee pawg xav tias Speco asphalt cog tuaj txog raws li ib qho kev sib tw thiab pib tsim tawm hauv 72 teev. Kev muaj tiag xav tau qhov tseeb hauv av. Ua ntej, lub hauv paus qhov tob yuav tsum siab tshaj 1.8 meters hauv av nplaum-nplua nuj av - peb pab neeg tau ntsuas kev sib haum xeeb ntawm 4.7 hli / hli ntawm lub ncoo ntiav hauv Tanzania, yuam kom rov kho dua txhua 11 hnub. Thib ob, cov khoom siv hluav taws xob yuav tsum tau ruaj khov 400V ± 2%, tsis yog "peb-theem fais fab." Qhov hluav taws xob poob qis dua 385V ua rau 12 lub tswb cuav ntawm PLC hauv qhov project Bangladesh tsis ntev los no. Thib peb, txoj kev nkag mus xav tau 12-tuj qag load ntsuas - tsis yog qhov dav - rau kev xa khoom; qhov kub bin module ib leeg hnyav 9.6 tons.
Tam sim no peb suav nrog cov ntawv txheeb xyuas qhov chaw npaj txhij nrog txhua cov lus hais. Cov no npog cov av compaction tests (CBR ≥95%), transformer deb txwv (≤45 meters los ntawm lub ntsiab vaj huam sib luag), thiab ambient suab mapping (kom tso lub suab nyob deb ntawm cov zos nyob ze). Hla ib kauj ruam ntxiv 11-19 hnub rau commissioning. Ib tus neeg tau txais kev cawmdim $210,000 nyob rau hauv cov neeg ua haujlwm tsis ua haujlwm los ntawm kev khiav peb daim ntawv teev npe ua ntej nchuav pob zeb.
Tus nqi ua haujlwm tsis yog roj xwb-Nws yog lub sijhawm poob haujlwm, kev ua haujlwm, thiab khoom seem
Kev siv roj tseem ceeb - tab sis nws tsuas yog 37% ntawm tag nrho cov nqi khiav lag luam tshaj li 5 xyoo lub neej. Cov levers loj dua yog kev saib xyuas cov sij hawm ua haujlwm, cov sij hawm ua cov khoom seem, thiab tsis tau teem caij nres. Speco asphalt cog tsim txo tag nrho peb. Piv txwv li, lub nruas tsav siv ncaj qha-coupled motors es tsis txhob ntawm chain-thiab-sprocket systems. Qhov no tshem tawm cov kev ntsuam xyuas nruj txhua lub lim tiam, roj cov ntsiab lus, thiab hloov cov saw hlau txhua 4,200 teev. Hauv kev xyaum, kev saib xyuas kev ua haujlwm tau nqis los ntawm 18.5 mus rau 6.2 teev / lub lis piam ntawm 2022 Sri Lanka installation.
- Hnav cov hnab looj tes siv AR400 steel nrog cov ntu hloov tau-tsis yog hloov nruas
- Tswj vaj huam sib luag nkoj nrog kev kuaj mob offline: cov kws tshaj lij txheeb xyuas qhov tsis raug ntawm lub sensor yam tsis tau txuas rau huab servers
- Cov khoom seem (burner nozzles, thermocouple assemblies, conveyor siv) Tshuag hauv zos hauv 14 lub teb chaws - suav nrog Nigeria, Nyab Laj, thiab Peru
Qhov no tsis yog theoretical. Thaum lub thermocouple ua tsis tau tiav thaum 3 teev sawv ntxov thaum hmo ntuj tseem ceeb hauv Oman, pab pawg ntawm lub xaib tau hloov pauv hauv 22 feeb siv cov khoom siv los ntawm lawv cov khoom siv ntawm qhov chaw - tsis tos rau huab cua thauj khoom. Qhov ntawd yog kev ua haujlwm ruaj khov ua rau hauv cov khoom siv kho vajtse, tsis tau cog lus hauv daim ntawv cog lus kev pabcuam.
Saib tom ntej: Kev sib koom ua ke, tsis yog kev sib cais
Cov pem hauv ntej tom ntej tsis yog cov nroj tsuag loj dua - nws yog kev sib koom ua ke ntse dua. Speco asphalt cog controllers tam sim no txhawb Modbus TCP thiab OPC UA raws tu qauv tawm ntawm lub thawv, ua kom cov ntaub ntawv ncaj qha xa mus rau kev tswj kev pavement xws li Pavement Management Information System (PMIS) lossis Autodesk BIM 360. Peb tab tom pom cov neeg cog lus sib cuam tshuam nrog lub sijhawm tiag tiag asphalt ntsuas kub nrog cov qauv ntsuas tom qab cov txiaj ntsig muaj zog - 1.8 correlation nruab nrab 23% ntau dua rutting tus nqi tom qab 18 lub hlis. Qhov kev pom ntawd hloov pauv li cas lawv calibrate mix designs.
Taian Yueshou Mixing Equipment Co., Ltd., nyob rau hauv Taian, Shandong Province, Suav teb, tau kho cov tshuab no txij li xyoo 1990. Nrog rau ntau tshaj 1200 tus neeg ua haujlwm thiab 110,000 square metres ntawm qhov chaw tsim khoom, lawv ua qhov tseem ceeb tshaj tawm cov lus pom zoo tshaj li cov qauv ntsuas ntsuas-xws li ntxiv corrosion-resistant stainless cladding rau tag nrho cov hopper interiors tom qab rov hais dua cov chloride-induced pitting nyob rau hauv ntug dej hiav txwv tej yaam num. Lawv speco asphalt cog kab qhia txog qhov ua haujlwm - tsis yog qhov zoo ntawm daim ntawv qhia.
Kev ua tau zoo hauv kev tsim kho txoj kev tsis yog hais txog kev caum tus lej siab. Nws yog hais txog kev tshem tawm kev sib txhuam: nruab nrab ntawm huab cua thiab cov zis, nruab nrab ntawm cov nplooj ntawv spec thiab av, nruab nrab ntawm kev saib xyuas thiab hnav tiag tiag. Speco asphalt cog kev daws teeb meem ua pov thawj tias thaum engineering hwm qhov tseeb-tsis yog txoj kev xav xwb-txoj kev tau tsim sai dua, muaj zog dua, thiab pheej yig dua. Pib nrog cov xwm txheej uas koj ntsib—tsis yog lub peev xwm uas koj cia siab rau.
