Release time：2024-06-12 02:30viewed：times
Technical parameters:
1. Input power supply: single-phase AC220V±10% 50Hz, power 1000W.
2. Multi-wing low-noise fan parameters: *r volume 2000 m3/h, wind pressure 1000 Pa, power 370W.
3. Experimental tube size: Φ32 × 250mm, made of copper tube. An electric heater with a power of 300W is installed in the tube as a heat source, and four thermocouples are embedded in the tube wall to measure the wall temperature.
4. Pitot tube flowmeter is equipped with an inclined tube micro-pressure meter to measure the flow rate: measuring range -10-700pa.
5. The experimental *r duct is made of transparent organic glass and is divided into *r outlet section, experimental section, test section, etc., which are connected by flange nuts for easy disassembly.
6. The temperature is measured by a high-precision temperature sensor . The universal signal input inspection instrument cooperates with a high-precision digital display meter to display all experimental measurement parameters such as temperature, resistance, and flow rate. The damper adjusts the *r volume.
7. Dimensions: 1800×500×1700mm, st*nless steel movable bracket with double brake wheels.
8. Virtual simulation software for electrical installation of building buildings and smart buildings. Based on unity3d design, users can choose different interactive interface sizes according to computer configuration, and six levels of image quality are av*lable. The model in the software can be rotated 360°, enlarged, reduced, and translated. There are assistant prompts during the use of the software, and the content is as follows: A. Wet alarm system 1.
