重庆升降机的液压系统均采用普通管式液压阀，泄漏量大抗、污染能力和工作可靠性差、升降平台液压系统的效率低、故障多、能耗高，液压阀不便于集成安装，体积和所占空间较大，难以满足机器的结构和使用要求，而插装阀的诸多优点恰恰能克服这些不足。
Wenzhou lifting platform hydraulic systems are used ordinary tube hydraulic valves, anti-leakage volume, poor pollution ability and reliability, low efficiency Wenzhou lifting platform hydraulic system failure, high energy consumption,the hydraulic valve is not easy to integrate the installation, the volume and occupies a larger space, it is difficult to meet the requirements of the machine structure and use, and the many advantages of cartridge valve is precisely to overcome these deficiencies.

升降平台液压系统还要能实现工作台的上升、下降、调速、过载保护、势能回收等功能，并要求结构简单、抗污染能力强、效率高、运行平稳、工作可靠，据此，用插装阀设计了升降平台液压系统。
Wenzhou lifting platform hydraulic system also enables the table to rise, down, speed, overload protection, potential energy recovery and other functions, and requiring a simple structure, strong anti-pollution, high efficiency, stable, reliable, accordingly, with cartridge Valves Wenzhou lifting platform designed hydraulic system.

系统采用蓄能器实现势能的回收和再利用，采用2个并联的二级伸缩式单作用油缸，作为执行元件来驱动工作台的升降，用机械方式保证2个油缸的同步运动；采用由限压式变量叶片泵和调速阀组成的容积—节流调速回路控制油缸的运动速度；油泵的输出压力由负载决定，溢流阀做系统安全阀用。
The system uses an accumulator Wenzhou lifting platform to realize the potential of recycling and reuse, the use of two parallel two single-acting telescopic cylinders, as the actuator to drive the lift table with a mechanical means to ensure synchronous movement of two cylinders; by limiting the use of volume-pressure variable vane pump and control valve composed - throttle speed loop velocity control cylinder; the output pressure of the pump depending on the load,relief valve for system use.
