In order to broaden the students' knowledge and broaden their horizons, I also use the color wall charts to display the school's no equipment through the color wall charts in front of the students, and there are also exploded views in these three-dimensional pictures, which means that the whole machine is decomposed into various The components enable students to observe the internal structure more detailed and more realistic. Of course, practice is of course the main point, theoretical teaching is still the focus, after all, most of the teaching content is taught to students through the teacher's story in the classroom. Classroom teaching also requires skill. In addition to detailed descriptions, the characteristics of school students should be explained in depth, and according to the unique characteristics of each type of machine tool in the machine tool class, help students build confidence and encourage them to learn new things. A class of machine tools is used as a new starting point. From the beginning, don't be intimidated by previous difficulties, thus improving your academic performance.
If a new heating cable is replaced, the entire device must be shut down, the insulation layer and the insulation layer on the outside of the cylinder are removed, and the entire damaged cable is removed and replaced, and the time for disassembly and assembly is required to take at least 3 days. The repair process does not require disassembly and insulation, and the device does not have to be shut down (A old equipment switch), and all work can be completed in less than one day, greatly reducing the workload. The whole heating cable is about 60m long, and it takes more than 20 turns around the cylinder with a diameter of about 0.9m. The surrounding space is also very small, and it is very troublesome to disassemble and install. Moreover, due to the need to bend and straighten many times, if the construction is improper, it is easy to cause the new heating cable to be pointed and damaged, because the repair method can avoid the adverse effects on the equipment during the replacement process. For other types of heating cables, such as structural and fault conditions, this method can also be used for repair. (Finish)
