01 Hoʻonohonoho e lawelawe i ka hoʻihoʻi ʻana i ka ʻoihana aupuni
ʻO ka manawa mai ka makahiki 1949 a hiki i ka makahiki 1952, ʻo ia ka manawa o ka hoʻihoʻi ʻana i ka hoʻokele waiwai o koʻu ʻāina.Ma muli o ka pono o ka hoʻokele waiwai, makemake nui ka ʻāina i ka nui okiwikā, ʻaʻole walenā kī kī haʻahaʻa, akā, he pūʻulu puʻupuʻu kiʻekiʻe a me waena i hana ʻole ʻia i kēlā manawa.Pehea e hoʻonohonoho ai i ka hana valve e hoʻokō ai i nā pono koʻikoʻi o ka ʻāina he hana koʻikoʻi a paʻakikī.
1. Alakaʻi a kākoʻo i ka hana
E like me ke kulekele o ka "hoʻomohala ʻana i ka hana, hoʻomaikaʻi i ka hoʻokele waiwai, me ka noʻonoʻo ʻana i ka lehulehu a me ka pilikino, a me ka pōmaikaʻi ʻana i ka hana a me ke kapikala", ua ʻae ke aupuni o ka lehulehu i ke ʻano o ka hana ʻana a me ke kauoha ʻana, a kākoʻo ikaika i nā ʻoihana pilikino a me nā ʻoihana liʻiliʻi. wehe hou a hoʻopuka i nā kiwi.Ma ka Eve o ka hookumu ana o ka People's Republic of China, ua pani hope ka Shenyang Chengfa Iron Factory i kana oihana ma muli o ka nui o na aie a aole makeke no kana mau huahana, waiho wale 7 kanaka hana e kiai i ka hale hana, a kuai 14 mīkini paahana e malama. na lilo.Ma hope o ka hoʻokumuʻiaʻana o New China, me ke kākoʻo o ke aupuni o ka poʻe, ua hoʻomaka ka hale hana i ka hanaʻana, a ua piʻi ka nui o nā limahana i kēlā makahiki mai ka 7 a hiki i ka 96 i ka wā i hoʻomaka ai.Ma hope mai, ua ʻae ka hale hana i ka hoʻoili ʻana i nā mea mai Shenyang Hardware Machinery Company, a ua hana hou ka hana.Ua hoʻonui ʻia ka nui o nā limahana i 329, me ka hoʻopuka makahiki o 610 sets o nā valves like ʻole, me ka waiwai hoʻopuka o 830,000 yuan.I loko o ka manawa like ma Shanghai, ʻaʻole i wehe hou ʻia nā ʻoihana pilikino i hana i nā valve, akā me ka hoʻihoʻi ʻana o ka hoʻokele waiwai o ka ʻāina, ua wehe a hoʻololi ʻia ka nui o nā ʻoihana liʻiliʻi liʻiliʻi i ka hana ʻana i nā valves, ka mea i hana i ka hui ʻana o ka Hui Lako Paʻa ma hoonui koke ia manawa.
2. Hoʻohui kūʻai a kūʻai aku, hoʻonohonoho i ka hana valve
Me ka nui o nā ʻoihana pilikino e huli ana i ka hana valve, ʻaʻole hiki i ka Shanghai Construction Hardware Association ke hoʻokō i nā koi o ka hoʻomohala ʻana.I ka makahiki 1951, ua hoʻokumu nā mea hana valve o Shanghai i 6 mau ʻoihana hui e hana i ka hana ʻana a me ke kauoha ʻana i nā hana o ka Shanghai Purchasing Supply Station o China Hardware Machinery Company, a hoʻokō i ke kūʻai like ʻana a me ke kūʻai aku.No ka laʻana, ʻo Daxin Iron Works, ka mea e hana ana i ka hana o nā kiwi haʻahaʻa haʻahaʻa nui nominal nui, a ʻo Yuanda, Zhongxin, Jinlong a me Lianggong Machinery Factory, e hana ana i ka hana o nā kiʻekiʻe kiʻekiʻe a me ka waena-pressure valves, ua kākoʻo ʻia e ka Shanghai. Ka 'Oihana o ka 'Oihana o ka 'Oihana o Kina Hikina a me ka Central Fuel.Ma lalo o ke alakaʻi ʻana o ka Petroleum Administration of the Ministry of Industry, hoʻokō ʻia nā kauoha pololei, a laila huli i nā kauoha hoʻoponopono.Ua kōkua ke Aupuni Kanaka i nā ʻoihana pilikino e lanakila i nā pilikia o ka hana ʻana a me ke kūʻai aku ma o ke kulekele kūʻai a me ke kūʻai aku ʻana, ua hoʻololi mua i ka anarchy hoʻokele waiwai o nā ʻoihana pilikino, a hoʻomaikaʻi i ka hoihoi o nā ʻoihana a me nā limahana, ka poʻe i hope loa i ka ʻenehana, nā lako. a me nā kūlana hale hana Ma lalo o nā kūlana, ua hoʻolako i ka nui o nā huahana valve no nā ʻoihana koʻikoʻi e like me nā mea kanu mana, nā mea kanu kila a me nā māla aila e hoʻomau i ka hana.
3. Hoʻomohala no ka hoʻihoʻi ʻana i nā lawelawe kūkulu hale hoʻokele waiwai
Ma ka papahana mua ʻelima mau makahiki, ua ʻike ka mokuʻāina i 156 mau papahana kūkulu nui, kahi o ka hoʻihoʻi ʻana o Yumen Oil Field a me Anshan Iron and Steel Company ʻelua mau papahana nui.I mea e hoʻomau ai i ka hana ʻana ma Yumen Oilfield i ka hiki, ua hoʻonohonoho ka Petroleum Administration Bureau o ka Ministry of Fuel Industry i ka hana ʻana i nā ʻāpana mīkini ʻaila ma Shanghai.Ua hana ʻo Shanghai Jinlong Hardware Factory a me nā mea ʻē aʻe i ka hana o ka hoʻāʻo ʻana-hana ʻana i kahi pūʻulu o nā puʻupuʻu kila waena.Hiki ke noʻonoʻo i ka paʻakikī o ka hoʻāʻo ʻana i nā kiwi puʻu waena e nā hale hana liʻiliʻi.Hiki ke hoʻohālike wale ʻia kekahi mau ʻano e like me nā laʻana i hāʻawi ʻia e nā mea hoʻohana, a nānā ʻia nā mea maoli a hoʻopaʻa ʻia.No ka mea ʻaʻole i lawa ka maikaʻi o nā mea hoʻoheheʻe kila, pono e hoʻololi ʻia ke kino pahu kila kila mua i forgings.I kēlā manawa, ʻaʻohe mea hoʻoheheʻe ʻia no ka hana oblique hole o ke kino valve honua, no laila hiki ke wili wale ʻia e ka lima, a laila hoʻoponopono ʻia e kahi mea hoʻoponopono.Ma hope o ka lanakila ʻana i nā pilikia he nui, ua lanakila mākou i ka hana hoʻāʻo ʻana o NPS3/8 ~ NPS2 medium-pressure steel gate valves and globe valves, i hoʻokipa maikaʻi ʻia e nā mea hoʻohana.I ka hapa lua o ka makahiki 1952, ua hana ʻo Shanghai Yuanta, Zhongxin, Weiye, Lianggong a me nā ʻoihana ʻē aʻe i ka hana o ka hana hoʻāʻo a me ka hana nui o nā kiwi kila kila no ka ʻaila.I kēlā manawa, ua hoʻohana ʻia nā hoʻolālā Soviet a me nā kūlana, a ua aʻo nā technicians ma ka hana ʻana, a lanakila i nā pilikia he nui i ka hana.Ua hoʻonohonoho ʻia ka hana hoʻāʻo ʻana o nā pahu kila kila o Shanghai e ka Ministry of Petroleum, a loaʻa pū kekahi i ka hui pū ʻana o nā ʻoihana like ʻole ma Shanghai.ʻO Asia Factory (i kēia manawa ʻo Shanghai Machine Repair Factory) i hāʻawi i nā hoʻoheheʻe kila i kūpono i nā koi, a ua kōkua ʻo Sifang Boiler Factory i ka puhi ʻana.Ua lanakila ka ho'āʻo ʻana i ka hana hoʻāʻo ʻana o ka prototype pahu kila kila, a hoʻonohonoho koke i ka hana lehulehu a hoʻouna ʻia i Yumen Oilfield no ka hoʻohana ʻana i ka manawa.Ma ka manawa like, ua hāʻawi pū ʻia ʻo Shenyang Chengfa Iron Works a me Shanghai Daxin Iron Worksnā kiwi haʻahaʻame nā ʻano nui i koho ʻia no nā mea kanu mana, ʻo Anshan Iron and Steel Company e hoʻomaka hou i ka hana a me ke kūkulu ʻana i ke kūlanakauhale.
I ka wā o ka hoʻihoʻi ʻana o ka ʻoihana aupuni, ua ulu wikiwiki ka ʻoihana valve o koʻu ʻāina.I ka makahiki 1949, ʻo 387t wale nō ka puka ʻana o ka valve, i hoʻonui ʻia i ka 1015t i ka makahiki 1952. Ma ke ʻano ʻenehana, ua hiki iā ia ke hana i nā kiwi kila kila a me nā puʻupuʻu nui haʻahaʻa haʻahaʻa, ʻaʻole ia e hāʻawi wale i nā kiwi like no ka hoʻihoʻi ʻana o ka hoʻokele aupuni, akā. hoʻokumu pū i kahi kumu maikaʻi no ka hoʻomohala ʻana o ka ʻoihana valve o Kina.
02 Ua hoʻomaka ka ʻoihana valve
I ka makahiki 1953, ua hoʻomaka koʻu ʻāina i kāna hoʻolālā mua ʻelima makahiki, a ʻo nā ʻāpana ʻoihana e like me ka ʻaila, ʻoihana kemika, metallurgy, mana uila a me ka lanahu i hoʻonui i ka wikiwiki o ka hoʻomohala ʻana.I kēia manawa, hoʻonui ʻia ka pono o nā valves.I kēlā manawa, ʻoiai he nui nā hale hana liʻiliʻi liʻiliʻi e hana ana i nā kiwikā, ua nāwaliwali ko lākou ikaika ʻenehana, ua kahiko kā lākou mau mea hana, ua maʻalahi kā lākou mau hale hana, ua liʻiliʻi ko lākou mau unahi, a ua puehu loa.I mea e hoʻokō ai i nā koi o ka hoʻomohala wikiwiki ʻana o ka hoʻokele waiwai o ka ʻāina, ke hoʻomau nei ka Ministry of Machinery Industry (i kapa ʻia ʻo ka First Ministry of Machinery) e hoʻonohonoho hou a hoʻololi i nā ʻoihana pilikino kumu a hoʻonui i ka hana valve.I ka manawa like, aia nā hoʻolālā a me nā ʻanuʻu e kūkulu i ka iwi kuamoʻo a me nā kī kī.ʻO Enterprise, ua hoʻomaka ka ʻoihana valve o koʻu ʻāina.
1. ʻO ka hoʻonohonoho houʻana o kaʻoihana valve lua ma Shanghai
Ma hope o ka hoʻokumu ʻia ʻana o New China, ua hoʻokō ka Party i ke kulekele o ka "hoʻohana, kaohi a me ka hoʻololi" no ka ʻoihana kapitalista a me ke kālepa.
Ua ʻike ʻia aia he 60 a i ʻole 70 mau hale hana valve liʻiliʻi ma Shanghai.ʻO ka nui o kēia mau hale hana he 20 a 30 wale nō kānaka, a ʻo ka mea liʻiliʻi he kakaikahi wale nō.ʻOiai ʻo kēia mau hale hana valve e hana i nā valve, ʻo kā lākou ʻenehana a me ka hoʻokele ʻana i hope loa, maʻalahi nā mea hana a me nā hale hana, a maʻalahi nā ʻano hana.Hoʻokahi wale nō a ʻelua paha mea hili maʻalahi a i ʻole nā mea hana mīkini kāʻei, a aia kekahi mau kapuahi crucible no ka hoʻolei ʻana, ʻo ka hapa nui o ia mau mea i hana lima ʻia., me ka hiki ʻole ke hoʻolālā a me nā lako hoʻāʻo.ʻAʻole kūpono kēia kūlana no ka hana hou ʻana, ʻaʻole hiki ke hoʻokō i nā koi hoʻolālā i hoʻolālā ʻia o ka mokuʻāina, a ʻaʻole hiki ke kāohi i ka maikaʻi o nā huahana valve.No kēia hopena, ua hoʻokumu ka Shanghai Municipal People's Government i kahi hui pū me nā mea hana valve ma Shanghai, a ua hoʻokumu i ka Shanghai Pipeline Switches No. 1, No. 2, No. 3, No. 4, No. 5, No. ʻoihana kikowaena.Hoʻohui i ka luna, centralized hoʻomalu ma ka 'ike loea a me ka maikaʻi, e pono unifies i ka hoopuehu a me ka chaotic hooponopono, pela nui mobilizing i ka ohohia o ka hapa nui o na limahana e kukulu socialism, keia ka mua nui reorganization o ka valve oihana.
Ma hope o ka hui aupuni pilikino i ka makahiki 1956, ua hoʻololi ʻia ka lua o ka ʻoihana valve ma Shanghai i ka lua a me ka hoʻoponopono hou ʻana o ka ʻoihana ma ke ʻano nui, a ua hoʻokumu ʻia nā hui ʻoihana e like me Shanghai Construction Hardware Company, Petroleum Machinery Parts Manufacturing Company a me General Machinery Company.Ua hoʻokumu ka hui valve i hui mua ʻia i ka ʻoihana ʻoihana hana ʻo Yuanda, Rongfa, Zhongxin, Weiye, Jinlong, Zhao Yongda, Tongxin, Fuchang, Wang Yingqi, Yunchang, Dehe, Jinfa, a me Xie ma ka ʻāina.Aia ma kahi o 20 mau hale hana kikowaena ma Dalian, Yuchang, Deda, a me nā mea ʻē aʻe.
