摘要:
根据连续速冻装置生产工艺和膨胀阀工作机理, 分析了膨胀阀在应用过程中产生自激振荡现象原因及其破坏性。从实践应用的角度推理出连续速冻装置热负荷占比对膨胀阀选型的影响, 得出了处理量在1 500 kg/h附近是热力膨胀阀稳定运行的极限的结论, 超过1 500 kg/h产能时建议采用电子膨胀阀, 进而提出了膨胀阀优化选型和自由振荡的解决方法。
Abstract:
According to the production technics of continuous fast-freezing device and working mechanism of expansion valve, the causes of producing self-excited oscillation phenomenon in the process of applying expansion valve and its destructiveness are analyzed. From the perspective of practical application, the impact of the proportion of thermal load of continuous fast-freezing device on selecting the type of an expansion valve is deduced. A conclusion is drawn that the processing capacity up to 1500 kg/h is the limit for stable operation of a thermal expansion valve. It is recommended to use an electronic expansion valve in excess of the capacity of1500 kg/h, and further propose a solution for optimizing selection of the type of an expansion valve as well as free oscillation.
