From today, we will study "universal mechanics and maintenance" with everyone. I hope you enjoy it! How to do a good job in this class, according to the technical situation of individuals on fishery and agricultural machinery and technical personnel, mainly from the following aspects and methods of research: First, the basic knowledge of general machinery. In other words, people usually have little knowledge of contact, and they still have technical problems that affect the service life of the machinery. These technologies will also make it difficult for mechanical technicians to grasp, but they must also master the technical problems that must be mastered by mechanical technicians. According to the experience of individuals studying and practicing research for many years, they should focus on the technologies that should be known and should highlight technical standards, specifications, and correct methods of operation. Secondly, according to the different cultural knowledge structures of all people, we adopt methods of induction and conciseness and easy-to-understand methods. We will strive to enable everyone to read and understand the lessons learned, to really learn some hard techniques, and for the advancement of human society and individuals in the future. The development of the business adds technical support. Third, this class we try to apply modern equipment and means, do a good job word processing, so that the combination of text and pictures to solve the problem of less physical and more text, as far as possible so that everyone at a glance, learn to have interest. Fourth, through the "General Mechanical Structure and Maintenance" technology course, so that friends willing to participate in this section can become qualified general machinery maintenance technicians. This is a personal subjective idea. Please cooperate with everyone to achieve this. Fifth, due to the application of online distance learning research, it is difficult for this class to have a certain degree of difficulty, coupled with the limited personal level. Errors are inevitable. Please guide and forgive. 6. If there are other requirements for mechanical technology, please contact by telephone. The contact details have been stated last time. Or consult China Agricultural Service Center. Finally, by the way, the basic knowledge of the three machines is one. What is general machinery? The so-called general machinery is the power machinery, that is, the engine equipment. All kinds of mechanical movement and operation are indispensable power, such as: cars, trains, aircrafts, ships and so on. Pictured
