6月4日,由宝鸡石油机械公司自主研制,具有自主知识产权的国内首台SL770新型水龙头,顺利通过2倍试拉载荷试验及各项功能性试验。SL770水龙头最大载荷为7700千牛,最高工作压力52兆帕,首台制造的整机试验压力达到78兆帕。宝鸡石油机械公司研究院的科研人员经过半年的研制,于今年6月终于将此产品研制成功,填补了国内空白。
On June 4, the first domestic SL770 tap with independent intellectual property rights, independently developed by Baoji Petroleum Machinery Co., successfully passed the 2 times trial load test and various functional tests. SL770 faucet maximum load of 7700 kN, the maximum working pressure of 52 MPa, the first test machine manufactured pressure reached 78 MPa. After six months of research and development, the researchers of the Research Institute of Baoji Petroleum Machinery Company finally succeeded in developing this product in June this year, which filled the domestic blank.
