水电厂的压力钢管承受经常变化的内压,一旦破坏,小则迫使电厂停产,大则使整个电站瘫痪。这类事故在国外已多次发生。日本1959年一年内就发生过三起,引起了日本技术界的重视,开展了大量的工作,提出了许多值得重视的意见。本文拟从一个有严重缺陷的压力钢管已经安全运行了四十年的经验谈几点意见。 Hydropower plant to withstand the pressure pipe often changes in the internal pressure, once destroyed, the small forced the power plant shutdown, big then paralyzed the entire power plant. Such accidents have occurred many times in foreign countries. In 1959, Japan happened three times in a year, which aroused the attention of Japanese technical circles, carried out a great deal of work, and put forward many opinions that deserve our attention. This article intends to talk about the safe operation of a penstock that has been severely flawed for 40 years.
