Arrangement and method for heating hydraulic percussion device

The invention relates to an arrangement and a method for heating a hydraulic percussion device. Arrangement and method for heating a percussion device (9) of a rock processor (Rtm) under low temperature operating conditions. The arrangement comprises a pre-heating mode (WM) for feeding pre-heated hydraulic fluid through a feeding channel (19) to a hydraulic circuit (18) of the percussion device. One or more hydraulic pressure accumulators (Pa) are present in the hydraulic circuit. The feed channel is provided with a control element (CE) for limiting the feed of the preheated hydraulic fluid during the warm-up mode. The control element limits the feeding of the preheated hydraulic fluid in the feeding channel such that a separating element (Se) of the pressure accumulator does not move. 本发明涉及用于加热液压冲击装置的布置和方法。用于在低温操作条件下加热岩石处理机(Rtm)的冲击装置(9)的布置和方法。所述布置包括预热模式(WM)，用于将预加热的液压流体通过给送通道(19)给送到所述冲击装置的液压回路(18)。在所述液压回路中存在有一个或多个液压蓄压器(Pa)。所述给送通道设有用于在所述预热模式期间限制所述预加热的液压流体的给送的控制元件(CE)。所述控制元件限制所述预加热的液压流体在所述给送通道中的给送，使得所述蓄压器的分离元件(
