The Maintenance Electrician Training examination device uses the modular design of the common, according to the different content configuration corresponding training module, the practical training is convenient, the layout is reasonable, is easy to expand and upgrade, the training content covers the electrical instrumentation, the electrical wiring technology, electronic circuit, electrical lighting distribution, electric power drag, single-chip Microcomputer, PLC comprehensive training, frequency conversion speed, electric shock first aid, safety fire, etc., in line with senior electrician in China Professional standards teaching, training, test requirements, adapt to the vocational schools, technical schools, secondary schools, The training of labor training and skills appraisal institutions and other units of the teaching, practice, skills appraisal.

  In addition to the maintenance of electrical training and testing equipment, PLC programmable control experimental device. PLC programmable control experiment device is a kind of device which combines PLC technology with programming control device, and simulates the real equipment in the start-up state through the operation of the device. PLC programmable control experimental device, belongs to medium kinetic energy equipment type.

  Vibration and prompt operation of improper, is a feature of this equipment. This kind of equipment material chooses conforms to the material, with sees the science and technology level and the product quality is the progress, the development tendency is chooses the high tech synthesis material. In addition, PLC programmable controller experimental device on the basis of "PLC Programmable controller Experiment System", increase plus SCM experimental development system, to achieve a single computer, resource sharing, easy to manage, the system can complete 51 96 808, such as CPU single-chip microcomputer, computer software and hardware experiments. On the basis of single chip computer simulation experiment System. Increase plus 80,886-bit microcomputer principle and interface experiment. Integrated design, just replace the different CPU card, can support a variety of CPU experimental development. Provides two kinds of operation platform, can work independently, also can work on-line with PC. A machine in the hand, there is no other. It is suitable for "the principle and interface of MSC-5", "MSC-96 MCU Principle and Interface", "SCM Interface Technology", "16-bit microcomputer principle and interface" and other courses teaching. The single Chip computer simulation experiment system composed of Mcs-51 card, in addition to the experimental function, also has the simulation development function, can simulate 8031/32, 87 89 51 52, 89c1051, 80C196KB and other CPU, external simulation space up to 64K. The purpose and contents of each experiment are described in detail in the guide book, the wiring diagram, the program Interface diagram and the program floppy disk are listed, which eliminates the teacher and the experimental tutor for the design, prepare to debug the experimental circuit and the experimental program of the workload, save the classroom time, engaged in single-chip application development teaching of scientific research personnel according to their actual needs to use the experimental system, can help users with the shortest time accurate and effective completion of the development and experimental tasks. The complete set of devices is reasonable in design, powerful in function and easy to operate.

  Building equipment simulation device, reverse airflow to dust off, the two ways to cooperate with each other, improve the cleaning effect, especially for fine particle sticky dust. In order to withstand the higher temperature, the industry also has the application of PTFE fiber and even metal fiber, but because of the high cost of its application is restricted. With a framed form, compact structure. This type of building equipment simulator requires the use of softer, structure, good wear-resistant filter material, priority for medium thickness needle felt filter material, the unit area is $number ~ 500g. In the laboratory, there is no difference between the chemical and physical parts and the equipment selection. For large and medium-sized building equipment simulation devices commonly used circular, no dust-removing skeleton; preference is given to satin (or twill) woven filter materials, and in special experiments can be used to strengthen the unit area of Shan.
