摘要: AHV364可控震源气路系统虽然在可控震源系统中占有比例不大,但其对可控震源振动性能和行车发挥着关键作用。因气路系统部件大多裸露且长期运转,所以经过一定使用期后难免会出现各种故障现象。其常见故障通常表现为系统气压低、挂钩气缸不能正常开启、定心气囊压力不足、平板隔振气囊气压不足。本文参照气路系统原理图,并结合实践经验,针对AHV364型可控震源氣路系统常见气路故障进行了分类汇总和深入详细的分析,并给出了排除故障的方法及使用保养建议,以供同行借鉴。

Abstract: Although the AHV364 vibrator Pneumatic system occupies a small proportion in the vibrator system, it plays a key role in the vibration performance and driving of the vibrator system. Because most of the components of the Pneumatic system are exposed and long-term operation, so after a certain period of use will inevitably appear a variety of failures. Its common faults are usually characterized by low system air pressure, the hook cylinder can not be opened properly, the air pressure of the mass suspension airbag is insufficient, the isolation airbag air pressure is insufficient. Referring to the engine structure principle and working principle, and combined with practical experience, this paper summarizes and analyzes in details the common faults of the AHV364 vibrator Pneumatic system, and gives the method of troubleshooting and the maintenance recommendations for peers′ troubleshooting.

AHV364可控震源由机械系统、发动机、液压、气路、电子等系统组成。参见图1。其中,气路系统由发动机空气压缩机、空气干燥罐、空气储气罐、平板隔振气囊、重锤定心气囊、气动刹车系统、挂钩气缸、挂钩气缸控制阀、气管等部件构成。由于可控震源工作时频繁剧烈抖动的特点,气路系统经过一定使用期后常会出现一些故障,这些故障与气路部件有关,也与作为动力源的发动机有关。气路系统虽结构简单,但气路系统故障对可控震源振动性能和行车发挥着关键作用,为提高气路系统故障排除和维修效率,有必要对气路系统常见故障进行理论联系实践的分析,从而归纳总结出解决方法,以期提高气路系统故障排除和维修效率,并能对气路系统进行预防性维护保养,减少气路系统更大故障发生率和损坏率。……
