聚能加热装置供热现场试验

聚能加热装置技术的核心是液体聚能供暖装置,该装置以电为驱动力,利用液体空化现象对介质进行加热,借助于水将机械能直接转化为热能。在相同的条件下,聚能加热装置的提温率远远高于电辐射板,而且节约电能132 kW.h,节电率达到了50%以上。目前喇嘛甸油田有注入站18座、配水间70座,采用加热缓冲装置进行供热的注水站10座,若全部采用聚能加热装置进行供热,则每年可节电548.52×104 kW.h,节约天然气185.6×104 m3,节约生产运行成本480.63万元。

空压机中间冷却器噪声的消除

我矿东区空压机站1980年安装了一台 L5.5—408型空压机,几年来运行正常。去年底发叫中间冷却器有异常声响,经检查,中间冷却器缓冲室的隔板平面弹性增大了。分析其原因:空压机600rmin.隔板每分钟受气流冲击为2×600=1200次,长年累月,使冲击平面扩张;由于三面焊在壳体上,势必导致中间部位微凹,使隔板变得松驰。这时.再度受气流冲击,中间冷却器就会发出金属振鸣声.干扰值班人员的听觉。

Regional Stress Field and Seismic Dynamics Along the Border Zone Between Fujian, Guangdong and Jiangxi Provinces

The regional stress field and seismic dynamics along the border zone between Fujian, Guangdong and Jiangxi Provinces are studied based on the seismo-geological data,GPS measurement, and seismicity. The results show that: (1) the principal compressional stress of the stress field is oriented in NW-SE direction and the principal extensional stress is in NE-SW direction; (2) the WNW-ward compression and collision of the Philippine Sea Plate to the eastern coast of Taiwan Island are the most direct and most important dynamic source for preparation and occurrence of strong earthquakes in the Taiwan Region and along the border zone between Fujian, Guangdong and Jiangxi Provinces.
