We all know that excavators are used in many tunnels or construction sites. When we dig with excavators, because our long-term use will cause the heat of excavator excavation. What should we do if the excavator has heat?

　　下面给大家解释一下挖掘机挖斗是如何发热的。

　　Here's how the excavator bucket heats up.

　　(1)油箱容积太小，辐射面积不够，油冷却设备未安装，或冷却设备容量太小。

　　(1) The volume of the tank is too small, the radiation area is not enough, the oil cooling equipment is not installed, or the capacity of the cooling equipment is too small.

　　(2)根据快进定量泵系统泵的选型能力，在运行中以流量限制大的高压溢流阀和发热溢流阀。

　　(2) According to the pump selection ability of fast-forward quantitative pump system, high pressure relief valve and heat relief valve with maximum flow restriction are used in operation.

　　(3)当卸载回路未设置为停止工作时，系统中的卸载回路发生故障或泵无法卸载。所有流量泵在高压下溢流，造成溢流损失和热量，导致油受热。

　　(3) When the unloading circuit is not set to stop working, the unloading circuit in the system fails or the pump can not unload. All flow pumps overflow under high pressure, resulting in overflow loss and heat, resulting in oil heating.

　　(4)弯管过长，弯管过多，局部压力损失和压力损失大。

　　(4) The elbow is too long, the elbow is too long, and the local pressure loss and pressure loss are large.

　　(5)零件精度不够，装配质量差，相对运动间的机械摩擦损失很大。

　　(5) The accuracy of parts is not enough, the assembly quality is poor, and the mechanical friction loss between relative motion is very large.

　　(6)部分配合间隙过小，或使用后间隙过大磨损，大量泄漏，导致大量损失，如泵容积效率降低，加热迅速。

　　(6) Part of the clearance is too small, or the clearance after use is too large wear and tear, a large number of leakage, resulting in a large number of losses, such as reduced pump volume efficiency, rapid heating.
