Release time：2024-06-10 01:00viewed：times
Technical parameters:
1. Operating environment: temperature 0-400C, relative humidity: ≤90%RH, power supply: 220V/50Hz, continuous operation possible.
2. Adopt low-noise, silent and environmentally friendly water pump, maximum lift: 10m, rated flow: 12L/min, power: 90W.
3. The experimental water tank has a volume of 30L and is made of transparent plexiglass. It is equipped with a pressure-stabilizing overflow port. The constant-pressure water supply tank is equipped with a water level adjustment mechanism to change the experimental flow rate; it can measure the Pitot tube pressure difference and the upstream and downstream pressures of the submerged orifice. difference.
4. Measuring water tank: Made of transparent organic glass with a capacity of 10L, with a measuring scale.
5. Water storage tank, 500×400×400mm, made of PVC board.
6. The pressure gauge is fixed on the pressure measuring frame by four plexiglass tubes with a diameter of φ8mm. There is a scale attached to the pressure measuring frame for easy reading. The indicating liquid in the differential pressure gauge is water, which is non-toxic and safe to operate.
7. Experimental flow rate: 0～200ml/s, Pitot tube applicable range is 20～200cm/s, experimental flow rate range is 100～200cm/s.
8. The fluid-water used in the experiment is designed for full circulation use, fully saving water resources.
9. The frame and tabletop are made of 304 st*nless steel, with compact structure, beautiful appearance and easy operation.
10. Overall dimensions: 1500×500×1550mm (length×width×height), movable design, with casters and locking feet.
11. 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 can choose from six image quality levels. 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.
