重慶升降機(jī)的液壓系統(tǒng)均采用普通管式液壓閥，泄漏量大抗、污染能力和工作可靠性差、升降平臺液壓系統(tǒng)的效率低、故障多、能耗高，液壓閥不便于集成安裝，體積和所占空間較大，難以滿足機(jī)器的結(jié)構(gòu)和使用要求，而插裝閥的諸多優(yōu)點(diǎn)恰恰能克服這些不足。
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.

升降平臺液壓系統(tǒng)還要能實(shí)現(xiàn)工作臺的上升、下降、調(diào)速、過載保護(hù)、勢能回收等功能，并要求結(jié)構(gòu)簡單、抗污染能力強(qiáng)、效率高、運(yùn)行平穩(wěn)、工作可靠，據(jù)此，用插裝閥設(shè)計(jì)了升降平臺液壓系統(tǒng)。
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.

系統(tǒng)采用蓄能器實(shí)現(xiàn)勢能的回收和再利用，采用2個(gè)并聯(lián)的二級伸縮式單作用油缸，作為執(zhí)行元件來驅(qū)動工作臺的升降，用機(jī)械方式保證2個(gè)油缸的同步運(yùn)動；采用由限壓式變量葉片泵和調(diào)速閥組成的容積—節(jié)流調(diào)速回路控制油缸的運(yùn)動速度；油泵的輸出壓力由負(fù)載決定，溢流閥做系統(tǒng)安全閥用。
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.
