Comprehensive experimental device of gas heating cycle

The comprehensive tr--ning device of the gas boiler hot water heating circulation system "digital volume control module is the control core, and the upper unit state software is used as the monitoring interface to display the working status and operating parameters in real time. The three basic parts are composed, and there are expansion water tanks, circulating water pumps, heat meters, self -force pressure difference control valves, electric flow regulating valve, solenoid valve, automatic exhaust valve, temperature collection module, pressure collection module, traffic collection module, etc. Affiliated equipment can form three different system forms: single -tube custody, single -tube leap type, and two -tube next -type backback type. It is suitable for higher vocational colleges, vocational school --r -conditioning engineering majors, heating ventilation and architectural majors Teaching and tr--ning of related courses.

2. Technical performance

5. Gas, liquefaction gas

Third, system configuration

1. Tr--ning desk

The tr--ning table adopts a st--nless steel combination structure, and the entire heating system is arranged on the mesh board.

2. Hot water heating system

The system consists of gas heat water boilers, heating pipes, heat sinks, expansion water tanks, circulating water pumps, heat meters, self -force pressure difference control valves, electric flow regulating valves, solenoid valves, turbine turnover sensors, pressure transmitters, temperature sensors, Equipment composition of automatic exhaust valves.

The system organically combines the fluid transportation and pipeline disassembly system, and cooperates with the basic practical m--ntenance and operation capabilities of the pump valve, disassembling and exercise of the general control of chemical engineering and chemical equipment m--ntenance workers.

The pipeline disassembly equipment system is m--nly composed of cont--ners, pumps, pipes, valves, instruments, disassembly tools, pressure test equipment, tool material shelves, etc. The system not only exercise the pipeline disassembly capacity of chemical equipment, but also tr--n the installation of chemical automation instruments and installation of the pump body.

1. The characteristics of the system
