The upgrade of voltage level doesn ’ t promote the performance of switch packages , before the national integrated design of a new generation 10kv high automatic switch didn ’ t start , normally all the switches manufacturer only refit the high automatic switch from 6kv to 10 kv pressure mutual inductance device and refit the display in voltage from 6kv to 10 kv in protector . because of the size and cubage of switches doesn ’ t change so much , upgrade of voltage level will create serious interfere problems of protector 电压等级的提升并没有带来开关柜的性能提升,在新一代的10kv高爆开关全国联合统一设计没有进行之前,各开关柜厂家基本上是将6kv高爆开关的电压互感器简单改为10kv电压互感器,将保护器的电压显示简单地由6kv改为10kv 。由于开关柜的体积尺寸并基本没有改变,电压等级的升高对保护器的抗干扰问题带来了较大的影响。
Fluid noise mainly comes from out put pulsation of rate of flow , the main reason of out put pulsation of rate of flow is the instant high pressure return flow that obturation cubage produced when the big round curve pressure transition . the v trough on the port plate can reduce the fluid noise . in this paper , the author based on the acting of dam a river and condensability of liquid and used matlab language as tool to calculate the v trough on the original port plate and drew out the p - t diagrammatic curve and analyzed its shortcoming and improved the design of original v trough and got that the best size of its angle was 12 . 3 and its length was 5mm and the cross section was an equilateral triangle 流体噪声主要来源于输出流量脉动，造成输出流量脉动的主要原因是闭死容积在大圆弧段压力切换时产生的瞬时高压回流，在配流盘上开设v型尖槽可降低因高压回流而引起的流体噪声，本文以截流作用和液体的可压缩性为理论依据，以matlab语言为工具，对原配流盘上的v型尖槽进行了理论计算，绘制出p - t图线，分析了它的不足，并对原有v型尖槽进行了优化设计，得出了v型尖槽的最佳几何尺寸：配流盘平面上的v型尖槽的两边的夹角为12 . 3 ，槽长5mm ，槽的横截面为等边三角形。
Along with computer functions more powerful , cost reducing , especially because of hardware cubage reducing greatly , power cost falling , software developing fast and networks prevelence , many electronic productions which can be linked to internet gains ground every aspects of people ’ s life in embedded sysytem modes 随着计算机功能的日益强大,成本减少,特别是由于硬件体积大大缩小、功耗降低,计算机软件的快速发展和计算机网络的全面普及,大量可接入互联网的电子产品以嵌入式系统的方式普及到人们生活的各个方面。
On the basis of enough theoretical study for hydraulic motor with multi cylindrical gear , under the condition of satisfied the output volume request , a designing method of parametrically designing hydraulic motor with multi cylindrical gear is proposed aiming at minimal cubage with by means of visual c + + 6 . 0 software , and some designing method examples are provided for verifying the accuracy and possibility of those design methods 本文在对圆柱多齿轮式液压马达进行理论研究的基础上,根据排量设计要求,以体积小为设计目标对该类型马达进行了参数化设计软件的开发,并通过设计实例验证了设计方法的正确性与可行性。
