Along with the rapid development of society， the energy demand for energy， the development is more and more Coal is one of the major domestic energy as its development has entered the increasingly tense At the same time， the coal mine safety hidden underground ventilation to come， the extremely important， as the most important link of ventilation equipment of coal mine main fan operation more directly related to the production and operation of coal mine safety of Therefore， the main parameters of coal mine ventilator real-time detection， the key is to ensure safety in The main performance parameters are fan speed， air， air pressure， the shaft power， efficiency， One main fan speed is the most direct characterization of operation Wind is reflected master key parameters of fan， at the same time， the ventilator bearing directly reflect the underlying hidden fan， bearing temperature is to understand the important parameters， the state of bearing axial fan of the radial vibration of the fault is important By understanding the four most important parameters， the staff can prompt understanding of main fan operation state， promptly eliminate hidden dangers to solve the Choose good dynamic characteristics of high sensitivity， the sensor， the corresponding input channel is the most important parameters in four complete collection， and take some anti-disturbance Choose simple interface functions， the single chip microcomputer as the core processor， complete signal collection， read， the keyboard and While the acousto-optic alarm， facilitate design working personnel to understand and grasp the main
Mechanical engineering is concerned with the power of a door production engineering Machinery industry is provided for the national economy， the basic industries will be equipped with the development of science and technology and produce Most important， that must be translated)Mechanical engineering related is the natural science and technology as the theoretical basis， combining with the production practice of technical experience， research and development， design， manufacture， installation， use and repair machinery theory and practical problems in the application of (this is also very important)Mechanical engineering related is the natural science and technology as the theoretical basis， combining with the production practice of technical experience， research and development， design， manufacture， installation， use and repair machinery theory and practical problems in the application of Modern society is mechanical manufacturing and service of five factors (people， capital， energy and materials and machines)， and one in energy and material The more important)My father is a 1984 and shandong college graduates， industrial and distribution to machinery factory When I was young I always see him in his factory work until he gets off work， then to have a strong interest in By my father in my later education， I learned that engineering is a need good combination of theory and practice， not only have the professional knowledge and rich theory have strong ability and practice ability， the knowledge to use perfect work to be My father once said to me， "the man must not only smart engineering， super " Since then， I have decided to study the mechanical engineering， the study of Now， after these days in shandong university study of mechanical engineering knowledge， I have a more profound Shandong university students to mechanical engineering education is in the way of education in shandong polytechnic university under the premise of the 21st century， with the new situation faced by a series of reforms， formed a unique way of Shandong university of mechanical engineering students can adapt society's demands， leading to social progress， and contribute to the The students， as well as mechanical engineering students all， not only to the teacher taught by the professional knowledge and rich practical courses， the special requirement to the engineering training center for In addition， in the year before the graduate school， students will also go to the factory organized practice， fully understand the actual situation， know how to correctly apply knowledge and strengthen their practice In addition， through years of understanding， and through the Internet search I understand that the engineering education in China and foreign born of engineering education still has many different Although these are different， but it is different countries have different conditions of the Each university in with the international standard， according to their country's national education plans to determine the specific， cultivate true for At this point， shandong university will do very well， mechanical professional teachers to teach basic theoretical knowledge and teach the most advanced knowledge of China， and according to the specific conditions of college students is most suitable for mountain arrangement plan， make mountains adequately， comprehensive university， so that they can contribute to the motherland after
Mechanical engineering， machinery and power generation with a relevant engineering Machinery and equipment industry is to provide the basis for the national economy， industry， the development of science and technology with a (This the most important and must be translated) Mechanical engineering is the science of natural science and technology based on the theory， combined with technical experience in the production practice， research and resolve in the development， design， manufacture， installation， use and repair of all machinery in the application of theoretical and practical issues (This is also very important) Mechanical engineering is the science of natural science and technology based on the theory， combined with technical experience in the production practice， research and resolve in the development， design， manufacture， installation， use and repair of all machinery in the application of theoretical and practical issues Machinery of modern society the five elements of production and services (people， money， energy， materials and machinery) of， and participation in energy and materials (This is more important) My father was in 1984 and graduated from Shandong University of Technology Department of Mechanical Engineering， and then assigned to the machinery factory A child I often see him inside the factory of his work for him after work， at the time of the machine had a strong By then my father for my education， I learned that engineering profession， it is a good combination of theory and practice of professional， not only have a wealth of theoretical knowledge， but also have a strong practical ability and practical ability， to the the use of learned to do a perfect My father once said to me: "School of Engineering who not only smart， but also have superior practical " From then on， I set out to study engineering， studied mechanical Now， after these days in Shandong University， studying mechanical engineering knowledge， I have a more profound Shandong University， students of mechanical engineering education in the footsteps of Shandong University of Technology， under the premise of education， combined with the 21st century， facing new situations， through a series of reforms， developed a unique teaching Shandong University， trained to professional students can adapt to mechanical needs of the community， promote social progress and contribute to Mechanical engineering students， and all engineering majors， not only taught by professional teachers a wealth of theoretical knowledge， as well as specific practical courses， requirements to practice engineering training In addition， one year before graduation， the school will organize the students to the factory specialized training to fully understand the actual situation， to know how to properly apply the knowledge and strengthen their ability in In addition， through these years of understanding and information through Internet I understand that China's overseas engineering students engineering education and health education there are still many Although with these different， but this is because different countries have different national conditions of the University of each block， while in line with international standards， but also according to their national conditions to determine which specific educational programs to cultivate a real talent for the At this point， Shandong University， to do very well， mechanical professional teachers teaching the basic theoretical knowledge but also teach the most advanced knowledge， and according to China's specific national conditions and arrangements for the plan most suitable for mountain college students， so that Hill College full and comprehensive development， so that after graduation they contribute to the
