The characteristics of the profession are crucial.
The hydraulic transmission course is set up in the 8å…€17895 Convention for the inspection and evaluation of the ship's steering gear, the loader, the anchor machine, the cable cutter, and the other. The requirements are based on hydraulic machinery. It is necessary for management students. However, at present, in the course of the curriculum of marine engineering management, there are certain questions about the teaching of hydraulic transmission, mainly the following points. At present, the contents of the ship auxiliary equipment set by the undergraduate engineering management students of the undergraduate course are mostly involved. Most of them are required by the 3117895 Convention, and the subject of the ship is subject to the examination. However, the ship's auxiliary machine is subject to the class, and there are very few classes that accompany the transmission. It is difficult to form a compulsory course for the content of the semi-rich and more systematic. Taking the class schedule 1 of the contents of the ship auxiliary equipment of Jimei University's Marine College as an example, it can be seen that the hydraulic deck machinery involved in the hydraulic transmission content can only allocate 32 lessons. In such a small number of ships characterized by hydraulic machinery and management of various requirements, classes, arrangements are clearly not enough.
Content marine pump air compressor hydraulic, plate machinery ship refrigeration and air conditioning ship auxiliary boiler seawater desalination device ship anti-pollution equipment class teaching capacity ship auxiliary machine related hydraulic transmission teaching content including the following parts hydraulic drive principle hydraulic component control valve hydraulic Part and shape symbol of pump hydraulic motor and auxiliary components; hydraulic oil; hydraulic steering gear; hydraulic cargo lift; hydraulic anchor and winch.
The basic theory of the front part of the liquid taste transmission, the latter part is the working principle and management points of the ship hydraulic mechanical system. As far as the content is concerned, there are many basic theories of the hydraulic transmission taught. For example, liquid helium components and rigid parts are selected for hydraulic oil dyeing monitoring technology. Hydraulic system sealing devices and installation, cutting, etc., from a systemic point of view, the hydraulic swaying course lacks integrity, as for hydraulic components. Course Contents. Also involved in some of the basic wood components, there are many hydraulic components that have not been applied to the ship, such as hydraulic cylinder servo valve set diverter valve stacking valve. The hydraulic thrusting device, hydraulic adjustable pitch propeller and hydraulic hatch cover, which are missing in the ship hydraulic machinery course arrangement, are not included in the examination and evaluation requirements of the 7795 Convention, but as the senior crew of future turbine management, It is not enough to understand this aspect.
As mentioned above, in order to systematically master the basic theory of liquid helium transmission and comprehensively understand the hydraulic machinery of the ship, it is necessary to increase the total amount of class hours, and the lack of class time makes the teaching content too simplistic and lacks the breadth and depth.
Teaching materials and experimental engineers 1. The judges are called, and the students are required to go on board the ship for the final semester. They only have a year and a half to study at the school. Therefore, the curriculum must be guaranteed to meet the requirements of the Ministry of Education for basic courses, and also to meet the sea boat. It is difficult for the crew to meet the requirements if they are qualified. During the period of entering the professional course, the students are faced with the teaching materials on the basis of the teaching materials in the case of less professional courses. In the end, I read very little, 1 time, its materials, flashing and teachers are especially important in the selection of teaching materials. At present, there are very few textbooks to choose from, which can fully reflect the basic theory of hydraulic transmission and is suitable for the hydraulics of sea-going vessels. 1 is poor.
There are many types of hydraulic machinery for ships, and the cost of purchasing and setting is expensive. The hydraulic test equipment of various maritime colleges and universities, the total components required for the experiment; 6 shortage and shortage. It is obviously unrealistic to require all maritime colleges to have sufficient and complete experimental settings for each port.
For the teaching of cultivating marine application talents, experiment is also an important part of teaching. Classroom teaching and experiment are indispensable. What's more, 31 Jia 7895 also has requirements for the evaluation of hydraulic equipment operation.
How to make the hydraulic transmission teaching content better with the marine engine tube. The training objectives of professional students should be, and we should put forward new ideas for us.
Discussion on the reform of hydraulic transmission course 1. Course optimization setting According to the author's many years of teaching experience and the feedback information of students after boarding the work, the part of the hydraulic transmission that students learn during the school is lack of operation in practice. Too simple. At present, there are a wide variety of ships in the world, including general cargo ships such as general cargo ships, bulk carriers, cargo containers, container ships, refrigerated ships, oil tankers, liquefied gas carriers, passenger ships, and dredgers, cable drums, icebreakers, cranes, drilling vessels, etc. There are many types of hydraulic machinery on board, and the specifications are not the same. Students on board the ship will certainly encounter a variety of hydraulic machinery not covered by the textbook. If there is no solid professional knowledge, it is difficult to manage the hydraulic machinery when the duty transfer time is short and the marine technicians who are responsible for the management of electromechanical equipment materials within the scope of responsibility are immediately required. The following is the author's setting of the hydraulic transmission course, supplementing the course content with the elective course. This method is not available at the time of compulsory courses, and is summarized in the case of addition. The specific content of the lecture should be the basic theory of the hydraulic component pressure system sealing device and the installation requirements. Maintenance and maintenance of hydraulic systems for ships; fault diagnosis methods for hydraulic components of hydraulic components and troubleshooting methods for fault separation; introduction of various types of hydraulic deck machinery and management matters. This method is currently adopted by Jimei University’s School of Navigation. This method is optional. Students may choose not to choose an elective course. Some students may give up this elective course under the pressure of compulsory exams. Some are more difficult to choose. Suitable material.
What is the effect of teaching? Still waiting to observe, the basic theory of hydraulic transmission and the performance test of hydraulic components, the combination of component disassembly and assembly is set as the door course, and the hydraulic deck machinery is set as part. such. The pre-settings enable students to master the basic theoretical knowledge in a comprehensive and solid way after learning, and lay a solid foundation for the analysis of fault diagnosis and management of the hydraulic deck mechanical system in the interior of the ship auxiliary machine. It is also easier to select suitable teaching materials. In addition, for the students who intend to apply for the students, the new discipline of hydraulic transmission is a good choice. It is undoubtedly systematically mastering this subject. It is difficult to add the competitive strength of the postgraduate examination. This is a compulsory course. The class is still an elective course. As a compulsory course, add the total amount of class. As an elective course, students will pay attention to it. If the total amount of class hours cannot be increased, as an elective course, teachers must spend more energy to organize this course in order to attract students' attention.
First. The mechanical contents of the hydraulic deck are separated from the auxiliary machinery of the ship, and the required courses for the door are independently formed. This kind of setting is the best way to read the leaves to enter the hall, and the course progress is flexible! The teaching process is tempered, combined with the component disassembly and assembly and hydraulic equipment comprehensive training, students can grasp the knowledge they have learned very firmly, and lay a solid foundation for the work after graduation. However, the total class time after the expansion of the content requires 7080 class hours, and the increase of class time must compress the class time of other classes. This is the difficulty for the teaching management staff to arrange the basic courses of the basic courses and professional courses. Taking into account the professional characteristics of the maritime class, and the undergraduate year-end 98 and later students are required to participate in the national unified examination course issued by the Maritime Safety Administration, it is not unreasonable to arrange appropriate orientation to the professional course.
Courseware is used to better improve classroom teaching. Progressively improve the students' comprehensive skills. The teaching of hydraulic transmission must use computer-aided teaching software to make various scales and materials into ten computer files, which can be called up whenever the lectures are needed. By using computer graphics software to draw various parts of the ship hydraulic deck machinery. The spatial model, the stereoscopic sense of the strong students and the overall concept. At the same time, through animation and combined with multimedia image processing functions. Students are well versed in the abstraction and simplification of the course. The content of the solution not only can well solve the inconvenience caused by the reduction of the content of the course, but also the learning can be watched in the spare time, 1 software, greatly improving the teaching effect of the classroom. Therefore, the development of marine hydraulic deck machinery multimedia courseware as soon as possible has a very important meaning. The development of multimedia courseware requires teachers to have basic computer basic knowledge and professional knowledge. If the relevant institutions strengthen cooperation and jointly develop, they will get twice the result with half the merits of teachers. In order to suit the characteristics of marine engineering, the professional quality and quality of students can be improved. Teaching effect. Teachers should sum up the questions found after several sessions of the hydraulic transmission course. The types of ships that make full use of the students' employment are widely distributed. The types and forms of hydraulic machinery are much more difficult to manage, and the characteristics are widely collected. Hey, in-depth analysis and improvement of the content of the lecture. This also urgently requires teachers to master the principle of media optimization combination, and use it in teaching, constantly exploring and summarizing experience in practice to adapt to the needs of multimedia teaching in the new situation.
Experimental teaching The maritime major is an applied major that requires students to be motivated, that is, students must have practical, operational and analytical skills.
The importance of the experiment is self-evident. Disassembly and assembly of hydraulic components; performance test of hydraulic components; fault diagnosis and elimination of hydraulic devices and management methods. It is an important part of the teaching of liquid music transmission. In terms of hydraulic test equipment, colleges and universities have accumulated year by year, and there is a certain scale. However, no matter the number of test benches or the number of experimental devices, there are inadequacies in the number of students who have enrolled in colleges and universities. The question asks the teacher to carefully plan and arrange the time to think. It is effective to use the open experiment to test the effect. The teacher asked several experimental contents in advance. Communicate with the experimenter, students can self-group in the working hours, 58 people in the classroom. An experiment was proposed in advance, and the mountain experimenter guided the completion of the experimental project. This not only ensures the number of student experiments, but also allows students to have more mobile phone meetings, and the flexibility of the soul is liked by students.
In summary, how to master and apply hydraulic technology to improve the professional and technical quality of the marine management technicians from the ship's hydraulic fluid management, in line with the requirements of the 31 Jia 7895 Convention, is the focus of our teaching 7 content and mode reform, Hydraulic technology is improper or poorly managed, resulting in frequent failures and even affecting ship operations. Therefore, the training of the marine management professional students has a solid theoretical foundation and practical hands-on ability of ship hydraulic machinery installation, use and maintenance management. It is necessary to carry out teaching reforms on the liquid helium transmission course to meet the educational goals and to deliver qualified and qualified personnel for the development of the navigation industry.
