Masiku awiri ndi mausiku awiri a zomangamanga mosalekeza, vuto la ntchito mosalekeza m'mphepete mwa nyanja pansi pa mikhalidwe yovuta, Bohai gombe akulemba Taphunzira ulemerero, Chengdao Oilfield molimba mtima mapewa udindo wolemera, embellishes "wokongola mafuta utoto" pa nyanja... M'zaka zaposachedwapa. , ndi Shengli Offshore Chengdao Oilfield Oilfield Crude mafuta kupanga akuchulukirachulukira, ndipo ntchito zazikulu zomanga m'mphepete mwa nyanja zikutuluka. Pakati pawo, nyundo ya SEMW H260MT ya hydraulic hydraulic piling nthawi zonse yakhala patsogolo pakumanga kuti zitsimikizire kuti ntchito yomanga ikupita patsogolo.
M'mwezi wa Ogasiti, m'madzi osaya kwambiri kum'mwera kwa Nyanja ya Bohai ku Dongying City, m'chigawo cha Shandong, SEMW idapanga pawokha nyundo yowonjezera nayitrogeni yowonjezera nayitrogeni ya H260MT hydraulic nyundo, yomwe idamaliza bwino gulu la CB208 la Chengbei block 208. Ntchito yomanga ku Chengdao Oilfield, Shengli Oilfield Kumanga ma seti 24 a milu yamapaipi achitsulo papulatifomu.
Ntchitoyi idapangidwa ndi Sinopec Shengli Oil Construction. Malo a mulu wa nsanja ya gulu lachitsime akukonzedwa monga momwe tawonetsera pachithunzichi. Milu yazitsulo zachitsulo kumbali zonse za nsanja ndizokwera pobowola mafuta kunyanja. Kutalika kwa mulu ndi 660mm ndipo kutalika kwa mulu ndi 79.75m. Ntchito yomangayo ikamalizidwa, kuya kwa muluwo mumatope ndi 60m. Chifukwa cha kusintha kwa mapangidwe, kutalika kwa mulu wa chokweracho kudakwera kuchoka pa 60m kufika pafupifupi 80m, ndipo nyundo ya dizilo ya D138 yomwe idakonzedweratu sinathe kukwaniritsa zofunikira zomanga. H260MT hydraulic nyundo ya kampani yathu ili ndi mwayi wotulutsa mphamvu zambiri / kuchuluka kwa mphamvu, zomwe zimangokwaniritsa zofunikira za wopanga ndikuyesetsa kuthana ndi ntchito yovuta.
Zimanenedwa kuti mulu wazitsulo zachitsulo za polojekitiyi zimagwiritsa ntchito njira yolumikizira mulu wa pamalopo, pafupifupi 20m / gawo. Milu iwiri yoyambirira imayikidwa mu muluwo ndi nyundo yogwedezeka. H260MT nyundo yama hydraulic yakampani yathu imapanga zolowera milu iwiri yomaliza ndi kutalika kwa 40m.
Kumanga gawo lachitatu la muluwo kumaphatikizapo nthawi yothandiza monga milu. Nthawi yapakati kuti mulu uliwonse ulowe muluwu ndi pafupifupi mphindi 40, mphamvu yogwira ndi pafupifupi 100 ~ 180kJ, maulendo ogwirira ntchito ndi 26BPM, ndipo chiwerengero cha kumenya nyundo ndi pafupifupi nthawi 800. . Kumanga kosalekeza kwa milu ya 24 kumbali zonse ziwiri kudzamalizidwa pambuyo pa maola pafupifupi 30 (kuphatikizapo nthawi yoyendetsa sitimayo).
Pambuyo pa kugwirizana kwa mulu, pomanga gawo lachinayi la milu, mphamvu ya nyundo ya hydraulic ili pafupi 200 ~ 230kJ, nthawi yogwira ntchito ndi pafupifupi 22 ~ 26BPM, nthawi yomanga mulu umodzi ndi pafupifupi 60 ~ Mphindi 90, ndipo kuchuluka kwa zikwapu za nyundo ndi pafupifupi mphindi 60-90. 800 ~ 1500 nyundo, zomwe 6 ~ 9m kulowa ndi kochepa kwambiri. Pambuyo pa masiku 2 ndi mausiku aŵiri akumanga kosalekeza, ntchito yomanga ya magulu aŵiri a milu 24 inatsirizidwa.
Kuphatikiza apo, milu yayikulu ya 4 ya φ1200 ndi kutalika kwa 104.669m ya nsanja idapangidwa ndi IHC S500, ndipo kukonzanso nyundo ya hydraulic kunamalizidwanso ndi kampani yathu.
Aka ndi nthawi yoyamba kuti nyundo ya H260MT ya hydraulic imamaliza kumanga milu yazitsulo zazing'onoting'ono pansi pazigawo zovuta pambuyo pomaliza kumanga milu ya Shanghai Tongji Road viaduct kumapeto kwa 2020. Kupyolera mu ntchito yomangayi, H260MT yalimbana ndi zovuta zopitirirabe. opareshoni pansi pazovuta kwambiri ndipo yayamikiridwa kwambiri ndi wogwiritsa ntchito.
Kukhala wokhoza kutenga nawo mbali m'mapulojekiti akuluakulu ambiri kumayenera kuthandizidwa kwambiri ndi zipangizo zamakono zamakono. SEMW HMT mndandanda wa nyundo zophatikizira ma hydraulic hydraulic piling amaphatikiza kafukufuku wozama komanso luso laukadaulo lamakasitomala pakufunika, amaphatikiza umisiri wolondola kwambiri komanso thupi limodzi, ndipo amakhala ndi mphamvu zochulukirapo. Amagwiritsidwa ntchito m'milatho yodutsa nyanja, nsanja zobowola mafuta m'mphepete mwa nyanja, minda yamphepo yam'mphepete mwa nyanja, Ntchito zazikuluzikulu monga madoko amadzi akuya komanso kumanga zilumba zopanga panyanja zachita bwino.
Chiyambi cha mankhwala a HMT hydraulic nyundo :
HMT mndandanda wa nyundo za hydraulic hydraulic mulung ndi nyundo zapamwamba kwambiri za hydraulic zomwe zidapangidwa ndikupangidwa ndi SEMW, zomwe ntchito yake yayikulu yafika pamlingo wapadziko lonse lapansi. Poyerekeza ndi nyundo ya mulu wa dizilo, nyundo ya mulu wa hydraulic ili ndi mawonekedwe aphokoso lochepa, palibe utsi wamafuta, kutulutsa mphamvu kwamphamvu, kutalika kwa mulu wakumira munjira iliyonse yogwirira ntchito, komanso kuwongolera kosavuta kwa mphamvu yogwira. Mndandanda wazinthuzi uli ndi ntchito zosiyanasiyana, kulamulira kwakukulu, kumangidwe kwakukulu, kuteteza chilengedwe ndi kupulumutsa mphamvu ndi kudalirika kwakukulu, ndipo onse ali ndi milu yambiri ndi njira zina zogwirira ntchito.
Mndandanda wa nyundo zopangira ma hydraulic ndi mtundu wochita kawiri. Pambuyo pa nyundo yamphamvu ikukwera mpaka kutalika kokonzedweratu ndi chipangizo cha hydraulic, pansi pa mphamvu yokoka ya mphamvu yokoka ndi mphamvu yokoka ya nayitrogeni woponderezedwa, liwiro lapamwamba kwambiri limapezeka, ndipo mphamvu ya nyundo ya hydraulic piling imapezeka. bwino. mphamvu.
HMT nyundo zophatikizira ma hydraulic nyundo zimayenderana ndi chiphunzitso cha nyundo chopepuka. Amadziwika ndi kulemera kocheperako kwa nyundo, kuthamanga kwamphamvu kwambiri, mphamvu yayikulu, komanso yoyenera kuyendetsa mulu wazitsulo. Ndi yoyenera kumapulojekiti akuluakulu monga milatho yodutsa nyanja, nsanja zobowola mafuta m'mphepete mwa nyanja, minda yamphepo yam'mphepete mwa nyanja, madoko amadzi akuya ndi zisumbu zopanga zakunja, ndipo ili ndi chiyembekezo chamsika wambiri.
Ubwino wa zomangamanga:
◆ Phokoso lochepa, kuwonongeka kochepa, kupulumutsa mphamvu, kuteteza chilengedwe ndi kudalirika;
◆ Mlingo wapamwamba wa automation, dongosolo lokhazikika, ntchito yosavuta komanso kulephera kochepa;
◆ Kudalirika kwadongosolo labwino komanso magwiridwe antchito amakina;
◆ Kusintha kosinthika, kusiyanasiyana kogwiritsa ntchito, kusintha kwamphamvu ndi kuthekera kolamulira.
