I. Overview

"Electronic Electronic Technology Experiment, Tr--ning Device" is a course of experimental tr--ning outlines such as "Electric Electronics Technology" and "Semiconductor Transformation Technology" and "DC Specific Specification" opened by colleges and universities. Tr--ning device. At the same time, it can be used as a skill tr--ning device for primary and intermediate m--ntenance electricians, senior electricians, technicians and senior technicians.

2. Technical characteristics

1. Safety and reliable: This device is powered by isolation transformer, and has ground protection and leakage protection functions. The safety meets relevant national standards to ensure personal safety; according to the characteristics of different experimental items, two different experimental connection cables are equipped , The strong electric part uses a high -reliable sheath structure pistol plug connection (there is no possibility of electric shock). The weak electric part uses elastic 铍 铍 铍 naked exposed structure connecting cables. Both wires can only be matched with the corresponding inner holes. This is great. Improve the safety and rationality of the experiment.

2. Strong scalability: It can meet the experimental teaching of the corresponding courses of various schools. The depth and breadth of the experiment can be flexibly adjusted according to needs, and the popularization and improvement can be organically combined according to the process of teaching. The device adopts a pendant structure and is convenient for replacement. If the expansion function is required or developed new experiments, you can just add a part and never eliminate it.

3. Strong intuitiveness: The experimental pendant adopts the form of separation structure. The front is the experimental schematic diagram and test point, which enhances the students' perception and rational understanding of the experimental content; It is conducive to improving students' practical ability.

4. Strong advancedness: The experiment involves four commonly used category variable -flow technical experiments, and most of them are widely used practical circuits, but for the convenience of teaching, but also the simplicity of this device; this device is considered from the height of the new device. The characteristic experiments of new devices, the driver of the new device, and the modern power electronic technology experiments of typical new device applications allow students to have sufficient understanding and understanding of new devices and keep up with the pace of the times.

Air source heat pump thermal machine tr--ning assessment device is a product developed in accordance with the requirements of the Ministry of Education's "Revitalizing the 21st Century Vocational Education Course Reform and Teaching Material Construction Plan", and develops in accordance with the requirements of vocational education teaching and tr--ning requirements. Suitable for high vocational colleges and vocational schools, cooling and heat -making technology, heat pump technology teaching tr--ning experimental tr--ning devices. The heat pump technology is one of the effective measures for recycling and using low -level thermal energy. Studying and promotion of heat pump technology is of great significance to energy conservation. With the development of refrigeration technology in recent years, heat pump technology has been applied in my country.

1. Device characteristics

1. The system crew is equipped with multiple protection systems such as high and low pressure protection systems, overload protection, lack of phase protection, and frosting functions to ensure the safety, reliable and stable operation of the system, and does not affect teaching courses.

2. The whole machine system is controlled by fully automatic and intelligent control. It is convenient to operate. Water temperature, water level, opening, control, and time can be freely set by the user. The whole machine uses the power -off automatic memory function.

3. This experimental device uses compressor, high -quality copper forging heat exchangers, high heat exchange efficiency, safe and reliable. The water tank adopts the advanced silver technology, combining fashion with top technology. The appearance of the equipment is beautiful and generous. The inside of the water tank is made of 304 st--nless steel. It is durable and is not easy to corrode and damage.

4. The system adopts industrial --r source heat pump thermal water units, which is consistent with actual industrial equipment, allowing teaching to be in line with actual applications. Outdoor hosts adopt a thick sheet metal p--nt type, with different experimental environments, and long -term effective work without rust and corrosion.

5. The entire tr--ning device integrates the --r source heat pump thermal machine system, electrical control system, and fault simulation system. The process system is truly complete, the structure is clear and compact, which fully meets the students' requirements for tr--ning.

6. The tr--ning device visually shows the system structure and working principle of the thermal pump -type water heater. It can be clearly seen that the structure of the heating circulation system and the m--n components can be clearly seen. The table, the real -time working state of the entire heat pump system is clear at a glance.

7. It can simulate the actual problems of the industry for f--lure settings. Students analyze the causes of the fault according to the process process, determine the scope of the f--lure, and conduct cause tr--ning.

8. Equipment pipeline: When the equipment does not change its performance without changing its performance, the device moves the original refrigeration pipeline reasonably to the experimental table and installed. , Different colors are used on the pipeline. The high pressure tubes are red and the low pressure tubes are blue.
