液压简一、结构原理液压筒是把油泵产生的液压能转变为直线运动的机械能的一种执行元件。用于电动手术台的主要有单向液压筒相双向液压筒(见图6、图7)。在单向液压筒内,压力油的液压力只作用在活塞(液压筒芯)的一侧,形成工作腔与回油腔的压力差,使与活塞相连的工作件向一个方向运动。反向运动则靠活塞杆自重、负载或弹簧力作用复位。双向液压筒
Hydraulic pressure is simple, the principle of the structure Hydraulic cylinder is the hydraulic pump to produce hydraulic energy into linear motion of an executive component of mechanical energy. For electric operating table is the main one-way hydraulic cylinder bi-directional hydraulic cylinder (see Figure 6, Figure 7). In the unidirectional hydraulic cylinder, the hydraulic pressure of the hydraulic oil acts only on one side of the piston (hydraulic cylinder), forming a pressure difference between the working chamber and the oil return chamber, so that the working member connected with the piston moves in one direction. Reverse movement by piston rod weight, load or spring force reset. Bidirectional hydraulic cylinder
