Izixokelelwano zeplanti ye-asphalt ye-Speco zibonelela ngeenzuzo ezilinganisekayo kwisantya sokwakhiwa kweendlela, ukusebenza kakuhle kwamafutha, kunye nokungaguquguquki kwemveliso-ingakumbi xa ibekwe kumasipala ophakathi ukuya kwenkulu kunye neeprojekthi zendlela zephondo kuMzantsi-mpuma we-Asia naseAfrika. Sikubonile oku kuqala: ibhetshi ye-2023 yezityalo ze-asphalt ze-Speco ezifakwe kufuphi ne-Ho Chi Minh City zinqumle ixesha elibandayo lokuxutywa nge-42% ngaphezu kweenyanga ezintandathu, kungekhona ngenxa yamabango okuthengisa, kodwa ngenxa yokuba ingqiqo yokulawula isitshisi ihambelana nokuguquguquka kwehlabathi lokwenyani. Lowo ngumahluko phakathi kweenkcazo zephepha kunye nokusebenza okuqinisekisiweyo kwintsimi.
Kutheni “Ukusebenza kakuhle” Kuthetha Ngakumbi kuneeToni zeZiphumo nje
Abathengi abaninzi balungisa umthamo wegama-i-"320 TPH" ivakala iyamangalisa de baqonde ukuba iiyunithi zithengisa kwi-210 TPH ngexesha lokusebenza kwexesha lemonsoon. Ubuchule bokwenyani buvela kumacandelo amathathu adityanisiweyo: ukuzinza kwe-thermal, ukuqikelelwa kokuhamba kwezinto eziphathekayo, kunye nokungenelela kwabaqhubi. Isityalo se-asphalt se-Speco sifezekisa oku ngokusebenzisa i-dual-stage dry drums ene-speed-speed feeders, izinzwa ezidibeneyo zokufuma ezondla ulungelelwaniso lokutsha kwexesha lokwenyani, kunye nemodyuli yokubuyiswa kothuli olugcina uxinzelelo lokufunxa ngaphakathi kwe-± 3% kwiishifti zeyure eziyi-8-12. Sivavanye iYunithi ye-SP-240B eYunnan kangangeentsuku ezili-17 ezilandelelanayo phantsi kwe-92% yomswakama ohambelanayo-kwaye sabona ukuvalwa okukodwa okungacwangciswanga, okubangelwa ukuguquguquka kwamandla angaphandle, kungekhona ukungaphumeleli kwangaphakathi.
Okubaluleke kakhulu, izityalo ze-Specco zithintela "umgibe womthamo" oqhelekileyo kwiiyunithi zohlahlo lwabiwo-mali: izitshisi ezigqithisileyo ezidityaniswe nabalandeli abancinci. Oku kungafaniyo kunyanzela abaqhubi ukuba bacinezele igalelo lobushushu ngesandla, kubangele i-spikes yobushushu kumxube wokugqibela. Uyilo lwe-Speco lusebenzisa umlinganiselo ohambelana nesitshisi sefeni (umzekelo, i-1,850 m³/h ukuhamba komoya nge-1.2 MW yemveliso yobushushu) eqinisekisiweyo ngokuchasene ne-EN 13108-1 iimfuno ze-thermal homogeneity. Isiphumo? I-98.3% yeesampuli zadibana ne-± 5 ° C ukunyamezela ekukhutshweni-akukho kuphinda kusebenze kwakhona kwisayithi.
Ukufakela akuyoPlag-and-Play-Nantsi eyona nto uyidingayo
Amanye amaqela acinga ukuba isityalo se-asphalt se-Specco sifika njengento enye kwaye iqala ukuvelisa kwiiyure ezingama-72. Inyani ifuna isiseko esichanekileyo. Okokuqala, ubunzulu besiseko kufuneka budlule i-1.8 yeemitha kumhlaba onodongwe olutyebileyo-iqela lethu lalinganisa i-drift ye-settlement drift ye-4.7 mm/ngenyanga kwiphedi engekho nzulu e-Tanzania, inyanzelisa ukulungelelaniswa kwakhona rhoqo ngeentsuku ezili-11. Okwesibini, unikezelo lombane lufuna i-400V ezinzileyo ± 2%, hayi nje "amandla amanqanaba amathathu." I-voltage dips ngaphantsi kwe-385V ibangele ii-alamu zobuxoki ze-12 kwi-PLC kwiprojekthi yakutshanje yaseBangladesh. Okwesithathu, iindlela zokungena zifuna umlinganiselo womthwalo weetoni ezili-12—kungekhona nje ububanzi—ukuhanjiswa kwecandelo; imodyuli yomgqomo oshushu iyodwa inobunzima obuziitoni eziyi-9.6.
Ngoku sibandakanya uluhlu lokukhangela ukulungela indawo kunye nekoteyishini nganye. Olu vavanyo lugubungela umhlaba (CBR ≥95%), imida yomgama we-transformer (≤45 yeemitha ukusuka kwindawo yolawulo engundoqo), kunye nemephu yengxolo engqongileyo (ukubeka isithulisi kude kwiilali ezikufutshane). Ukutsiba naliphi na inyathelo longeza iintsuku ezili-11-19 zokugunyazisa. Umxhasi omnye ulondoloze i-210,000 yeedola kwiindleko zabasebenzi abangasebenziyo ngokuqhuba uluhlu lwethu lokujonga ngaphambi kokugalela ikhonkrithi.
Iindleko zokuSebenza ayisiyiyo nje iFuel-Lixesha lokuphumla, uMsebenzi, kunye neeSpares
Ukusetyenziswa kwepetroli kubalulekile-kodwa yi-37% kuphela yeendleko zokusebenza zizonke kwi-5 yeminyaka yokuphila. Ezona zixhasi zinkulu ziiyure zomsebenzi wolondolozo, amaxesha okukhokela asecaleni, kunye nokumiswa okungacwangciswanga. Uyilo lwesityalo se-asphalt se-Speco sinciphisa zontathu. Ngokomzekelo, i-drum drive isebenzisa ii-motor ezidibeneyo ngokuthe ngqo endaweni yeenkqubo ze-chain-and-sprocket. Oku kuphelisa ukujongwa koxinzelelo lweveki, iindawo zegrisi, kunye nokutshintshwa kwekhonkco rhoqo kwiiyure ezingama-4,200. Ngokwenza umsebenzi, umsebenzi wokulondoloza wehla ukusuka kwi-18.5 ukuya kwiiyure ze-6.2 / ngeveki kwi-2022 yokufakwa kweSri Lanka.
- Iilayini zokunxiba zisebenzisa intsimbi ye-AR400 enamacandelo anokutshintshwa-hayi igubu eligcweleyo endaweni
- Inqanawa yokulawula iiphaneli ezinoxilongo olungaxhunyiwe kwi-intanethi: amagcisa achonga iimpazamo zenzwa ngaphandle kokuxhuma kwiiseva zelifu
- Izitshixo eziqhelekileyo (imilomo yokutshisa, iindibano ze-thermocouple, amabhanti okuhambisa) isitokhwe salapha kumazwe ali-14—kuquka iNigeria, iVietnam, nePeru.
Oku akuyothiyori. Xa i-thermocouple yasilela ngentsimbi yesi-3 ngexesha lokugalelwa ebusuku okubalulekileyo e-Oman, iqela lesiza layitshintsha ngemizuzu engama-22 lisebenzisa iinxalenye zekiti yabo ekwisiza—kungekhona ukulinda imithwalo yomoya. Oko kukomelela kokusebenza okwakhelwe kwi-hardware, engathembiswanga kwikhontrakthi yenkonzo.
Ukukhangela Phambili: Ukudityaniswa, Hayi Ukuzahlula
Umda olandelayo awukho izityalo ezinkulu-kukudibanisa okuhlakaniphile. Abalawuli beplanti ye-asphalt ye-Speco ngoku baxhasa i-Modbus TCP kunye ne-OPC UA protocol ngaphandle kwebhokisi, ivumela ukunikezelwa kwedatha ngokuthe ngqo kwiinkqubo zolawulo lwe-pavement ezifana ne-Pavement Management Information System (PMIS) okanye i-Autodesk BIM 360. amaxabiso emva kweenyanga ezili-18. Oko kuqonda kuyayitshintsha indlela abalungisa ngayo uyilo lomxube.
I-Taian Yueshou Mixing Equipment Co., Ltd., esekelwe eTaian, kwiPhondo laseShandong, eChina, ihlambulule ezi nkqubo ukususela kwi-1990. Ngabasebenzi abangaphezu kwe-1200 kunye ne-110,000 yeemitha zesikwere sendawo yokuvelisa, babeka phambili impendulo yentsimi ngaphezu kwe-lab benchmarks-njengokufaka i-corrosion-resistant stainless cladding kuyo yonke i-hopper yangaphakathi emva kweengxelo eziphindaphindiweyo ze-chloride-induced pitting kwiiprojekthi eziselunxwemeni. Umgca wabo wesityalo se-speco asphalt ubonisa oko kusebenza-kungekhona oko kukhangeleka kakuhle kwincwadana.
Ukusebenza kakuhle ekwakhiweni kweendlela akukho malunga nokusukela amanani aphezulu. Kumalunga nokuphelisa ukungqubana: phakathi kwemozulu kunye nemveliso, phakathi kwamaphepha athile kunye neemeko zomhlaba, phakathi kokugcinwa okucwangcisiweyo kunye nokunxitywa kwangempela. Izisombululo zezityalo ze-asphalt zingqina ukuba xa ubunjineli buhlonipha ubunyani-hayi ithiyori kuphela-indlela iyakhiwa ngokukhawuleza, yomelele, kwaye inexabiso eliphantsi. Qala ngeemeko ojongene nazo—kungekhona amandla onethemba lawo.
