在压缩机运行中,气阀工作的可靠性与耐久性具有头等重要的意义。为了确定气阀工作的效率以及寻求其易于损坏的原因,就必须全面地研究气阀的工作。这时,非常简单而准确地录取阀片升起图形具有很大的意义。因为根据它就有可能确定阀片落到阀座和升度限制器上的速度以及落到阀座上的滞后角。根抿图形的特性也能判断气阀通流截面的利用率、气阀完全开启的时间、阀片的振动及其升起和座落的特点。
In the compressor operation, the reliability and durability of the valve work is of paramount importance. In order to determine the efficiency of the valve work and to seek its reasons for easy damage, it is necessary to fully study the work of the valve. In this case, it is of great significance to take a very simple and accurate way to register the valve lift. Because on the basis of it it is possible to determine the speed at which the valve slides on the valve seat and the lift limiter as well as on the valve seat. The characteristics of the root 抿 pattern can also determine the utilization of the valve through-flow cross-section, the time the valve is fully open, the vibration of the valve plate, and the characteristics of its rising and seating.
