通用机械：预应力混凝土压力容器用预应力混凝土制成的压力容器。20世纪50年代末期﹐法国用预应力混凝土压力容器作气冷反应堆的压力壳。以后许多国家均在气冷反应堆上采用预应力混凝土压力容器﹐设计压力已达6兆帕。由于轻水型反应堆和煤转化用的钢质压力容器的尺寸不断增大﹐越来越难以用钢制造﹐在运输上也有很多困难﹐工程界正在进行以预应力混凝土压力容器代替钢质压力容器的可行性研究。混凝土的抗压性能好﹐但抗拉性能很差。为使混凝土在承受拉应力时不破坏﹐在其内部埋入高强度钢缆或钢筋﹐然后对钢缆或钢筋施加预拉伸应力﹐使混凝土承受较高的预压缩应力。这样﹐当预应力混凝土容器内承受工作压力时﹐作用在混凝土筒壁上的拉应力便被预压缩应力所抵消﹐而混凝土不承受拉应力。在容器内壁有一层薄的钢制衬里﹐以防止介质泄漏。用于高温的容器﹐在衬里层上加有绝热层﹐以防止混凝土温度过高。预应力混凝土压力容器有两个显著优点﹕ 可采用普通的设备在现场施工建造﹐容器的尺寸不受限制。当金属压力容器因直径过大﹑器壁过厚等原因而无法运输或制造时﹐可选用预应力混凝土压力容器。 这种压力容器的破坏模式与钢制压力容器不同﹐它是逐渐破坏的。钢衬里如有泄漏﹐介质沿混凝土的渗透是一个较慢的过程。此外﹐钢缆是互不相连的﹐如果个别钢缆出现裂缝﹐裂缝不会由一根扩展到另一根﹐因而容器具有高度的安全性。
