Grounding the machine is always necessary for the normal operation of the machine 为了正常安全运转,应安装地线。
At last , the safety of the system is important in any condition , so how to guarantee the safety of the system with any possible measure is a necessary portion of the paper 本文最后还分析了系统的安全机制,论述了如何采用各种措施来保障系统的安全运转。
Therefore , cultivation of safety culture consciousness in employees is of great significance in solving the establishment of safety culture in enterprise and assurance of safety in enterprise 因此,培养员工安全文化意识对解决企业安全文化建设及保证企业安全运转具有十分重要的意义。
Flow sensors si1007 monitor whether media normally flow in pipeline control product quality and equipment uptime and avoid considerable loss by product or equipment damage 检视管路中的流体是否正常流动,来控制产品的质量和设备的安全运转,以避免产品或设备遭受损害或停机的严重损失。
Flow sensors lk3023 detecting liquid level detect if liquid level is correct or not control product quality and equipment uptime and avoid considerable loss by product or equipment damage 检视管路中的流体位置是否正确,来控制产品的质量和设备的安全运转,以避免产品或设备遭受损害或停机的严重损失。
The crushing equipment must be equipped with the self - protection system in order to run safely at low fault level . and the overload protection system will play an important role in modern crushing equipments 这就要求设备本身应具有良好的自我保护系统,以使设备安全运转,故障率保持在低的水平上。因此,过载保护系统在破碎设备中占有着极为重要的地位。
In the control system of intelligent greenhouse , in order to monitor the working condition of each machine in real time , and guarantee that device of temperature control . device of humidity control , device of ventilation , device of lighting work safely . electric current of 3 phrases ac should be gotten and monitored , which can guarantee the machine work normally , safely and reliably 在智能温室控制系统中,为了实时监测各设备的运行状态,完好情况,确保温控装置、湿控装置、通风装置、补光装置等安全运转,需要对三相交流电流进行采样监控,以确保设备工作正常、安全可靠。
The second , a scientific accounting information system of perfect , prompt efficient and safe operation includes 3 essential factors at least : one is the employee troops that will have a high quality , person is basic ; 2 is to have perfect business management and built - in control system , system is ensured ; 3 is to wait for advanced science and technology using computer and network , technology is the foundation of establishing highway and carrier 第二,一个科学完善、及时高效和安全运转的会计信息系统至少包括三个要素:一是要有一支高素质的员工队伍,人是根本;二是要有完善的企业管理及内部控制制度,制度是保障;三是要利用计算机及网络等先进科学技术,技术是建立信息通道和载体的基础。
In this paper , a new way of real - time damage detection method was proposed according to the high speed working situation of the composite flywheels for energy storage , and a suit of equipment was developed to test the composite samples with piezoelectric disc built - in , the response waves before and after the damage occurred were recorded to the computer . on the base of traditional spectrum analysis of signal recorded , the wavelet analysis was introduced and the program in matlab language was made . with the wavelet packet decomposition of the signal , the relations between the change of response signals and damage characters were gotten , a database for damage recognition was created 本文结合储能复合材料飞轮高速旋转的工作特点,提出了一种在线检测飞轮转子损伤的方法,自主设计一套实验装置对模拟各种损伤的的试样进行了测试,试样损伤前后的响应信号被采集后存入计算机中;在对采集信号进行传统的频谱分析的基础上,引入了先进的小波分析理论,利用matlab语言编写程序,对信号进行小波分解,得到了信号变化和损伤特征之间的关系,建立了一个识别飞轮损伤的数据库;小波包分解得到信号对比图和特征向量,可以有效判定材料内部有无损伤和损伤的程度,结合频谱分析等,可一定程度上判定损伤的类型,为储能飞轮的安全运转和智能化运作提供了决策依据。
