摘　　要：BV-620LF型可控震源是从2013年开始投入使用的一种低频可控震源。目前由于此型号震源设备状况老化,加上野外恶劣的施工状况,经常出现合流电液逻辑控制及保护系统问题,导致合流切换不正常而无法行车的故障现象。本文介绍了一个典型的不行车故障排除案例,通过分析震源驱动及合流控制原理,找出了引起这一故障的原因。The BV-620LF vibrator is a low frequency vibrator that has been in use since 2013.At present,due to the aging condition of this type of seismic source equipment and the harsh construction conditions in the field,there are often problems with the control and protection system of the combined current electro-hydraulic logic,resulting in abnormal switching of the combined current and the inability to drive.This article introduces a typical non-case of troubleshooting a non-functional vehicle and identifies the cause of this fault by analyzing the principles of source drive and confluence control.
