Training device of water flow turbulence

1. Demonstrate the development of water flow and deepen the understanding of the water flow movement structure.

2. Deepen the understanding of the structure of the water flow, demonstrate the whole process of flowing layer flow, fluctuation formation and development, and fluctuations into vortex movement. Experimental analysis of motivation.

M--n configuration:

Water pump, water supply tank, T4 light source, color solution cont--ner, constant pressure water tank, infusion pipe, regulating valve, water removal pipe, mixture, shear flower display surface, exhaust valve, regulating pipe, returning water tank, st--nless steel, st--nless steel, st--nless steel Bracket

Technical Parameters:

1. Operating environment: temperature 0-40 ° C, relative humidity: ≤90%RH, power supply: 220V/50Hz. Can be continuously operated.

2. This device is a set of desktop miniature motivation experimental instruments. The low noise -free and rusty environmental water pump is used to achieve self -cycle.

3. This device can distinguish between the upper and lower fluids of the heterosexual, which can neutralize color after mixing, showing the colorful shape of the turbulent vortex.

4. Flow: Water supply ** flow QMAX = 300 ml/s experimental pipeline flow QP = 0-200 ml/s.

5. Silent and environmentally friendly water pump: r--sing: 10m, traffic: 12L/min, power: 90W.

6. Water storage tank, 500 × 400 × 400mm, material PVC board.

7. Back to the water tank: 10L, transparent and organic glass, with a measuring scale.

8. The fluid used in the experiment-water is full circular design, which fully saves water resources.

Features

 

The tr--ning model of the access control control system incorporates the anti -theft alarm system based on the single -machine access control control system. It not only expl--ns the basic system composition of the access control control system, that is, the controller+card reader+the opening door, but also uses common anti -theft alarm devices The door magnetic switch together constitutes a system that uses a house as a false protection object. The entry and exit of the door can only use the password card after authorization; the password+card and other ways to enter the house.

This model consists of the IBA AC-08 system controller, door opening, relationship, window vibration system, infrared detection device, alarm system, display system, etc.

 

M--n components IBA AC-08 Single-door controllers' functions

 

1) Open door method: password, card, password+card

2) Card capacity: 500 photos, card reading distance: 65mm

3) Operation mode: security mode, password switching

4) Built -in doorbell control, built -in anti -pile alarm

5) Keyboard: 12 Jianqi telephone keyboard

6) Operation tips: Fengming Yin, 2 3 -color LED indicator lights

7) Input voltage: 12-18VDC Input current Reference Value: 60mA

 

  Experimental content

 

Master the system composition of the access control control system and the anti -theft alarm system and the working principle of common equipment, and write your own control procedures based on the principle of control of your own understanding. Understand the working mode of the system controller, and more in -depth understanding through the control of practical permissions "can only enter and exit by authorization."
