冷饮生产中时常遇到膨化机或盐水槽不制冷及压缩机“走潮车”的现象。本文以流体力学的原理进行了分析,阐明了主要是由于某蒸发器中因突然加入大量的热负荷而使流体迅速由蒸发器排出。因此供液管流体产生倒流而无液,又因静液柱压强差的原因造成难以恢复供液;就此提出了相应的改进措施。 Cold drink production often encounter puffing machine or brine tank is not cooling and compressor “go tide car” phenomenon. This paper analyzes the principle of fluid mechanics, clarifying that the fluid is rapidly discharged from the evaporator due to the sudden addition of a large amount of heat load in an evaporator. Therefore, the liquid supply pipe backflow without liquid, but also because of the hydrostatic pressure difference causes difficult to restore the liquid supply; In this regard, the corresponding improvement measures.
