| 摘要 | A pressure indicator for a hydraulic hammer is provided. The pressure indicator includes a sleeve member configured to couple to an opening defined in a wall housing of an accumulator of the hydraulic hammer. The pressure indicator further includes a plunger slidably disposed within the sleeve member and movable between a first position and a second position with respect to the sleeve member. The plunger includes a first end disposed outside the wall housing of the accumulator. The plunger further includes a flange coupled to a second end. The pressure indicator further includes an elastic member inserted over the plunger and disposed between the wall housing of the accumulator and the flange. A position of the first end of the plunger with reference to an outer end of the sleeve member provides a visual indication of the pressure of the gas within the accumulator. | ||||||
