Release time：2024-06-12 08:30viewed：times
Purpose of the experiment:
to measure the heat release coefficient when *r flows transversely across the surface of a flat plate; and to organize the experimental data into a criterion equation based on a similar analysis of the heat release process of forced motion.
M*n configuration:
multi-wing low-noise fan, automatic adjustment damper, combined plexiglass wind tunnel, plexiglass experimental pipe section, copper flat specimen, solid voltage regulating module with potentiometer to adjust heating power, digital ammeter and voltmeter display The heating current, voltage, and *r flow are measured by a Pitot tube equipped with a differential pressure sensor , and the temperature is measured by a PT100 thermal resistor. The 8-channel universal signal input inspection instrument displays temperature, resistance, and flow rate, and the st*nless steel bracket is used.
Technical parameters:
1. Input power supply: single-phase AC220V±10% 50Hz, power 1.5KW.
2. Multi-wing low-noise fan parameters: *r volume 2000m3/h, wind pressure 1000 Pa, power 370W.
3. Specifications of electroplated copper flat plate specimen: δ=0.1 mm, length 250mm, width 180 mm, surface blackness ε=0.2, thermal conductivity λ=15 (W/m℃); electric heating power: 500W.
4. Pitot tube flowmeter is equipped with a differential pressure sensor: range 0-1000Pa, accuracy 0.5.
5. The experimental *r duct is made of transparent organic glass and is divided into *r outlet sections, experimental sections and test sections, etc., which are connected with flange nuts.
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 manual damper adjusts the *r volume.
7. Dimensions: 2000×500×1700mm, 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.
