Application of elastic variable - section pressure - equalizing groove in the structural design of high - stiffness aerostatic thrust bearing 用可变截面均压槽实现高刚度空气静压轴承的结构设计
Based on the experimental and numerical simulation results , a new equivalent plate thickness formula and new empirical formulas for the mean crushing load are given 基于实验结果和数值仿真的结果,给出了新的等效板厚和平均压溃载荷计算公式。
In addition , a way of by using the series of circuits instead of series of devices is adapted to halve the voltage stress of the secondary diodes 并且通过改进副边结构,将副边二极管器件的串联变为电路的串联,能够实现高频二极管的动态均压。
Output voltage and current is often distorted in half bridge converter because voltage unbalance of input capacitors though its application is very abroad 摘要半桥逆变器应用广泛,但存在直流分压电容不均压,使分压电容中点电压漂移,导致输出电压和电流畸变的缺点。
The purpose : breaker capacitor ( equalizing capacitor ) is connected in parallel to the port of high - voltage ac breaker , evens the voltages among ports during tripping 产品用途:断路器电容器(均压电容器)并联连接于高压交流断路器的断口上,使各断口间的电压在开断时均匀。
Abstract : based on the simulated laboratory experiment of pressure balance for fire extinguishing , the pressure regulating technique in the burning section of meiyukou coal mine is summarized 文摘:在采场均压防灭火实验室模型模拟实验的基础上,总结了煤峪口矿现场实施火区的调压工艺技术。
Of the three technical processes of the one without pressure equation , the one with pressure equation at the inlet and the one with pressure equation at the outlet , the last one has a low power consumption and thus is effective 目前微型变压吸附制氧有无均压、进气均压、出气均压3种工艺流程,其中有均压流程能耗较低、制氧效果较好。
