| 4. | Move your legs and feet for 3 or 4 minutes per hour while in your seat to get the muscle pump working and avoid stasis 在客舱座位中每小时活动腿部三至四分钟,令肌肉泵活动,避免血液凝固。 |
| 5. | Sliding bearing instead of the conventional rolling bearing , making pump working more smoothly with very little vibration and noise 用滑动轴承替代常规电机滚动轴承,使泵具有运行特别平稳,振动噪音极低。 |
| 6. | Move your legs and feet for 3 or 4 minutes per hour while in your seat to get the muscle pump working and avoid stasis 当您坐在座椅上时,每小时要移动一下您的腿和脚3至4分钟,从而产生肌肉泵的作用促进血液流通。 |
| 7. | An automatic control system of screw pump is introduced in this paper . accident is avoided while the screw pump works without slurry 介绍了一种螺杆泵电气自动控制系统,成功地避免了螺杆泵在无矿浆状态下运行造成的毁坏事故。 |
| 8. | With forward voltage of white led lower and lower , the efficiency of traditional charge pump driver is lower and lower , too . the new auto - adjustable charge pump can keep the charge pump working in high efficient 1x mode as long as possible 根据负载led的正向压降和输入电压选择工作模式,可以让驱动器最大限度地工作在高效率的1x模式下,有效地提高了驱动器的led效率。 |
| 9. | Unlike the traditional single mode of charge pump structure , the paper adopted 1x / 1 . 5x fractional adaptive charge pump , which can automatically convert working mode with the change of input voltage , and utilized ultra - low - dropout current regulators to make 0 . 15v led _ minimum regulation voltage in order to remain the charge pump working mostly in higher - efficiency 1x mode 与传统的单一转换模式的电荷泵结构不同,本文采用了1倍/ 1 . 5倍分数型自适应电荷泵技术,可随输入电压的变化自行转换工作模式;采用低压差电流调节器使led阴极最小调节电压仅为0 . 15v ,使电荷泵更多地工作在效率更高的1倍模式。 |
| 10. | 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。 |
