摘　　要：DENISION振动泵在工作过程中,有时会出现压力不稳或者压力下降的情况,从而导致可控震源无法正常工作。究其原因,是因为振动泵的多功能阀块出现了问题。本文介绍了振动泵多功能阀块的结构,阐述了多功能阀的工作原理,分析了多功能阀失效的故障原因,并详细地介绍了故障的排除方法。Sometimes the DENISION hydraulic pump will meet some failures, such as the instability pressure or pressure drop. Those failures will cause the vibroseis can＇t work normally. The fundamental reason is due to the multifunc- tional valve block of hydraulic pump problems. This paper introduced the working theory of the muhifunction valve, and analyzed the failure reasons, then presented the detailed methods for troubleshooting.
