Reciprocating compressors are widely used in the fields of petrochemistry and metallurgy. The design scheme for the compressor system must meet the demands of the highest operational power and flow; however, most of the actual operational states of the compressor are lower than the design state. Therefore, a stepless capacity method that functions through delayed closure of the suction valve has been proposed in engineering. The suction valve unloader can not only provide stepless changes in flow but can also save energy. Thus, it plays an important role in the industries under the global energy scarcity. However, this method can cause serious vibration and noise in practical applications.¹

具有无级调节功能的往复式压缩机系统中压力脉动的快速算法

往复式压缩机广泛用于石油化学和冶金领域。压缩机系统的设计方案必须满足最高工作功率和流量的要求；但是，压缩机的大多数实际运行状态都低于设计状态。因此，在工程中已经提出了通过吸入阀的延迟关闭而起作用的无级容量方法。吸入阀卸荷器不仅可以提供无级的流量变化，还可以节省能源。因此，它在全球能源短缺的行业中发挥着重要作用。但是，该方法在实际应用中会引起严重的振动和噪声。^1个
