例句與用法
- 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
指出雙速電動(dòng)機(jī)用于輸油泵的調(diào)速時(shí)，應(yīng)選用轉(zhuǎn)矩按轉(zhuǎn)速平方降低特性的電動(dòng)機(jī)；調(diào)速泵的運(yùn)行經(jīng)濟(jì)性受到管路阻力特性曲線的限制，其調(diào)速范圍受到管路阻力特性曲線、系統(tǒng)所需揚(yáng)程和泵運(yùn)行特性的限制；在母管制系統(tǒng)中把部分定速泵改為調(diào)速泵時(shí)，應(yīng)將性能較高的定速泵改為調(diào)速泵。
