我厂生产的液压锤后腔氮气蓄能器气室结构如附图所示。工作时活塞作往复直线运动，回程时活塞压缩氮气以储能，冲程时氮气膨胀并推动活塞对外作功。气室漏气将严重影响液压锤的工作，现将两种容易被忽视的气室漏气故障的排除办法介绍如下。 １．充气单向阀处密封失效引起的漏气 I plant after the production of hydraulic hammer nitrogen gas accumulator chamber structure as shown in the figure. Pistons work reciprocating linear motion, the return piston compression nitrogen to energy storage, nitrogen expansion stroke and promote the work of the piston. Gas chamber leak will seriously affect the work of the hydraulic hammer, now two easily overlooked gas chamber leak troubleshooting methods are as follows. 1. Pneumatic check valve seal failure caused by leakage
