对三种节流调速回路的效率进行了简要分析,列出了实验曲线,证明进、出口节流调速回路的效率可达0.7～0.8;相同条件下两者的效率相等;负载相同时调定压力相等;薄壁式与三角槽式节流阀调速回路的效率无明显差异。
The efficiency of the three kinds of throttling speed regulating circuits is briefly analyzed and the experimental curves are listed to prove that the efficiency of the throttling speed regulating circuits of inlet and outlet can reach 0.7-0.8; under the same conditions, the efficiencies of the two are equal; Set the same pressure; thin-walled and triangular slot throttle valve speed control circuit efficiency no significant difference.
