在本刊86年第三期发表的“球形补偿器的节能分析”一文中,介绍球形补偿器在热力管网中解决管道热膨胀方面与形补偿器相比来说,具有节能、变形应力小、补偿能力大、流体阻力小及节省管材等优点,这无疑是个很大的节约。本文笔者也非常同意这种看法,但它的结构形状还是较复杂,造价 In the article “Energy Conservation Analysis of Spherical Compensators” published in the third issue of the journal in the same issue, the article describes that the spherical compensator has the advantages of energy saving and small deformation stress compared with the shape compensator in solving the thermal expansion of the pipe in the heat pipe network. The advantages of large compensation capacity, low fluid resistance, and savings in pipes, are undoubtedly a great saving. The author of this article also strongly agrees with this view, but its structural shape is still more complicated and costly.
