背景技术
在缓冲减震领域，缓冲器运用十分广泛，其主要作用是吸收各种冲击能量、保护设备和降低噪音等。
但是缓冲器在使用过程中会产生一定的温度，持续工作，温度会聚集，需要进行降温处理，但是如何检测缓冲器内缓冲介质的温度,并保护缓冲器是本领域的技术难题。
发明内容

进一步，所述活塞体组件包括：所述活塞体组件包括：同轴排列的左、右活塞体，该左、右活塞体上对称设有3-9个用于介质轴向流动的通孔，左、右活塞体的相邻端面之间的密封配合，以使做活塞运动时，介质仅通过所述左、右活塞体上的各通孔实现往返流动；所述左、右活塞体上的通孔分别同圆周均匀分布在左、右活塞体上，以使介质往返流动时分布均匀；所述左活塞体内设有用于放置伺服电机的空腔，该伺服电机由所述PLC控制，其转子连接于所述右活塞体；其中，所述PLC根据各级缸体内的介质温度值，控制伺服电机带动相应的右活塞体旋转，以控制左、右活塞体上的各通孔的相对位置关系，进而控制介质流量，即控制活塞运动速度或关闭相应的首级或末级缓冲器。
与现有技术相比，本发明具有如下优点：（1）本发明通过温度传感器能及时反映缸内介质的温度情况，并且根据温度情况，控制缓冲器工作速度，即温度过高时，减缓相应的首级或末级缓冲器内的活塞工作速度；当高于限定值（警戒值）时，关闭相应的首级或末级缓冲器，以起到降温的作用，进而避免由于温度过高造成缓冲器损坏；（2）本发明克服了现有技术中由于冲击能量波动，而造成多级缓冲器无法协调工作的技术问题，本发明通过温度传感器检测介质温度过高时，适当的调节各级缓冲器的介质往返流量，以控制各活塞体组件的运动速度，使各级缓冲器协调工作，避免了可能出现的某一级缓冲器因为介质温度过高，造成缓冲器故障；（3）通过左、右活塞体中的各通孔配合，以控制相应缸体中的介质往返流量，从而改变相应活塞的往返速度，以降低各级缸体的介质温度，延长缓冲器寿命。
