更多例句： 上一页 - Dynamic characteristics of a7v225 braking variable pump , accumulators storage and outlet property , braking and auxiliary driving property of hydraulic systenu load ' s simulation of auxiliary driving and so on have been analyzed in the article . hydraulic storage braking and auxiliary soft starting of down belt conveyor have been simulated in laboratory , at the same time , have testified that this energy saving hydraulic system is available
通过实验，并应用了小波分析去噪等数据处理手段，文中对a7v225刹车变量泵的动态特性、蓄能器的储能和放能特性、液压系统的制动和辅助驱动特性及辅助驱动时负载的模拟等，分别进行了分析。 - The adoption of the variable pump is a breakthrough of the water cutting jet which solved the previously problems in suing the home - made products , such as piston pump filling - up , noise , high - consumption of energy , high oil temperature , lowering of piston pump pressure at the beginning of the work which would effect the starting point and the longevity of the high pressure components will be affected by the changes of pressure
采用变量泵是水刀的技术突破，以前用国内柱塞泵，噪音大、不节能、油温高，柱塞泵在开始工作时压力会降低，这样会影响切入点效果，高压部件会受到压力的变化而影响高压部件的使用寿命。 - It is indicated that , when a two - speed motor is used for driving oil transfer pump , the motor with the characteristic of torque reduction on square rotary speed should be chosen ; the working economy of the variable speed pump is restricted by the characteristic curves of pipeline resistance , and its speed control range is restricted by the pipeline resistance characteristic curve , the pressure head needed by the system and the working characteristic of the pump ; when several pumps work in parallel , the pump with better performance should be changed into speed - variable pump
指出双速电动机用于输油泵的调速时，应选用转矩按转速平方降低特性的电动机；调速泵的运行经济性受到管路阻力特性曲线的限制，其调速范围受到管路阻力特性曲线、系统所需扬程和泵运行特性的限制；在母管制系统中把部分定速泵改为调速泵时，应将性能较高的定速泵改为调速泵。
