Liability for consequential damage resulting Type 9329A … 9389AThese easy to install piezoelectric reaction torque sensors are particularly suitable for measuring rapidly changing torques at non-rotating shafts. Five different size sensors are available for the measuring ranges ±1 N·m, ±10 N·m, ±25 N·m, ±200 N·m and ±1 000 N·m.• Two calibrated measuring ranges: 100%, 10%• Very compact, ready to install reaction torque sensor• Flexible adaption with mounting threads in double flange • Centering seats for coaxial mounting and optimum intro-duction of torque• Centric bore for shaft passage• Can be used as torque calibration sensorDescriptionThe reaction torque sensor is integrated under high preload be-tween preload screw and nut. When a torque acts on a s ensor, the shear stresses produced are transmitted to the c rystals. The charge signal proportional to the force is picked up by an electrode and fed through a screened cable to a charge am-plifier. The charge signal is converted by the charge amplifier to a proportional output voltage, which can be r ecorded and evaluated.Flanges on the top and bottom sides of the reaction torque sensor allow simple and direct installation on a shaft or adapter flange. This allows very low, space-saving installation. Alterna-tively, a mounting flange (optional accessories) can be used or installation can take place using custom adapters. A two-sided centering facility allows very accurate coaxial fitting. A centric bore allows additional applications, e.g. for shaft bushing. A screw-on connector cover ferrule is provided with the included accessories to protect the cable connection at the side. Kistler reaction torque sensors reliably detect even the slightesttorques acting on the sensor axis in both rotary directions.M zApplicationThe sensor is suitable for measuring a dynamic or quasistatic torque acting on the sensor axis.Examples of Application• Torque setting of pneumatic screwdrivers • Testing screw connections• Calibration of manual torque wrenches • Torque testing of springs• Measurements on friction clutches• Measurement of starting torques on electric motors• Measurement of irregular rotation and torsional vibrations on small servo and stepper motors•Testing of rotary switches (product testing)Fig. 1: Reaction torque sensor with mounting flangePage 2/59329A _000-463e -07.23© 2013 ... 2023 Kistler Group, Eulachstraße 22, 8408 Winterthur, Switzerland Tel.+41522241111,****************,.

高压变频器在循环风机的应用一、前言目前，随着企业竞争的日益加剧，生产成本的高低决定了企业在市场竞争的地位，特别是水泥生产企业，很大一部分花在能耗上，降低水泥生产过程中的电能消耗越来越引起了业界的重视.在水泥生产过程中，风机被大量的采用于工艺流程上，而风机负载耗电量较大，起动电流较高，同时用电动阀门、挡风板等装置来调节风量，在风道系统设计时，为满足生产环境的最大要求，必须留有余量，因此风机的风量和压力往往偏大，功率的偏大设计必然造成能量的浪费。

很多的风机有30~70%的能量是消耗在调节阀的压降上的，不仅造成电能的浪费，工作效率低，而且开动阀门时，还发出啸声和振动，经常发生事故。

变频调速技术作为一种先进的电机调速方式，其优异的性能以及带来可观的经济效益早已为人们所知。

近几年来变频技术的出现，彻底改变了这一状况，实践证明在风机的系统中接入变频系统，利用变频技术改变电机转速来调节风量和压力的变化用来取代阀门控制风量，能取得明显的节能效果。

本文就SH-HVF系列高压变频器在华新金猫水泥（苏州）有限公司中应用进行分析总结。

二、变频器节能原理一般异步电动机的同步转速为：n1＝60f/p而异步电动机转速n与同步转速n1存在一个滑差关系：n= n1（1—s）=60f/p（1—s）由上式可以得到，改变异步电动机的转速可以通过改变f、p、s可以达到。

针对某一电动机而言P是一定的，而通过改变S进行调速空间非常小，所以变频调速通过改变定子供电频率f来改变同步转速是异步电动机的最为合理的调速方法。

若均匀地改变供电频率f，即可平滑地改变电动机的同步转速。

异步电动机变频调速具有调速范围宽、平滑性较高、机械特性较硬的优点，目前变频调速已成为异步电动机最主要的调速方式，在很多领域都获得了广泛的应用。

根据流体力学相似定律：Q1/Q2＝n1/n2 输出风量Q与转速n成正比；H1/H2＝(n1/n2)2 输出压力H与转速n2正比；P1/P2＝(n1/n2)3 输出轴功率P与转速n3正比。

a） 温度：环境空气温度随季节而变化，但最高+40℃，环境空气最低温度为-15℃； b） 海拔：不超过1000m；
注： 当环境空气温度、海拔与上述规定不同时按GB755规定；
c） 湿度：最湿月月平均最高相对湿度为90%，同时该月月平均最低温度不高于25℃（工厂）； d） 额定频率：50Hz； e） 工作制：S1； f） 额定电压：220V、230V、240V、380V、400V、415V、660V、690V、720V、220V/380V、230V/400V、 240V/415V、380/660V、400V/690V、415V/720V。
其中：W为户外防轻腐蚀；TH为湿热；WTH为户外湿热；F1为户内防中等防腐；F2为户内防强腐 蚀；WF1为户外防中等腐蚀；WF2为户外防强腐蚀； g) 为了方便连接负载，在电动机轴伸端面均预留有C型中心孔； h）优良的起动特性； i) 电动机的高质量保证了很高的运行可靠性； j）高效、节能、安全、环保。 今天，任何一个购买新电动机或者希望对原有电动机进行大修的人，都应该仔细地计算一下：采用 节能电动机是否更值得？一般情况下采用节能电动机是明智的，因为它是降低电能费用最有效的措施。 在分析电动机的费用时，典型的运行时间是每年3000小时，共运行十年，在这十年间购买、安装和 服务、维护的费用全部加在一起，约为总费用的3%。运行费用几乎全部是电能费用，却超过总费用的97 ％。如果能够在电能费用上得到节约，那么，只要电动机在运行，你就是节约的。尽管电动机的购置费 用较高，但可以在一年以内回收。然而上述计算不能单纯只看它的商业价值。电动机消耗了工业用电能 的60％，一项研究表明，由于驱动电机效率低下，每年造成电能的浪费近2000亿KW.h，它相当于2个三 峡电站每年的发电量；不仅如此，还要排放1100万吨的碳氧化物。这意味着，环境保护也受益于每台节 能电动机。 YE4 系列电动机的效率平均比 YE3 系列电动机平均效率高出 2%左右，图 1 列举了 YE4 与 YE3 系列电 动机中 0.75kW～90kW 效率的对比值，高出部分的效率所节约的电能费用，要远远超出所增加的费用。
