Single tube lift membrane evaporation experimental device

Observe the flow of fluid water in the membrane evaporator (bubble flow, bomb -type, stirring and circular flow).

Measure the dryness of the heat circulation and steam under different flow types.

Design Parameters:

The heat transfer coefficient: 1000-5000 (w/m.2.oc). Liquid flow: 4 ~ 40L/h, normal pressure operation.

public facilities:

Water: The device comes with a st--nless steel water tank and connects tap water. During the experiment, the centrifugal pump was entered into the test pipeline and was used in a circular.

Electric: voltage AC220V, power 2.5kW, standard single -phase three -line system. Each laboratory needs to be configured with 1-2 connection locations (safe and signal places).

Experimental materials: clean tap water, outer equipment: none.

Major equipment:

1. 304 st--nless steel steam generator: power 2.0kW, can be adjusted, bringing the insulation. The steam generator design has a safe water seal to eliminate the hidden safety hazards caused by the safety valve. The steam generator has a pressure protection device, which can be adjusted by pressure and can call the police at high and low pressure.

2. 304 st--nless steel heating section: φ22*750mm, power 0.2kW can be adjusted, with a warming layer.

3. The length of the glass observation section is 200mm quartz glass window. The observation window is a double -layer glass structure, which can protect the safety of observation. Organic glass tube protection.

4. 304 st--nless steel measurement section: φ18*500mm, the power of 0.2kW can be adjusted, and the insulated layer.

5, 304 st--nless steel liquid cooler: a pipe condenser, 0.1m2 heat exchange area.

6, 304 st--nless steel steam condenser: pipe condenser, 0.1m2 heat exchange area.

I. Overview

 

1. Electric soft starter (soft starter) is a novel motor control device that integrates soft starting, soft parking, light -loading energy saving and multiple protection functions. This product can effectively limit the starting current of AC asynchronous motor. It can be widely used in loads such as fans, pumps, conveying classes, and compressors. The ideal replacement product of the pressure equipment.

 

2. "Electrical Soft Starting Control Real Tr--ning Cabinet" is the needs of the installation, commissioning, and m--ntenance of motor startup equipment in various industries in the society. The skills tr--ning developed by courses such as technology "," Factory Electrical Control ", and" Motor Drag and Control "is the tr--ning and assessment equipment of relevant units such as various professional education centers, tr--ning institutions, and vocational appr--sal stations (institutions). Tr--ning equipment for electrical related majors in various vocational colleges.

 

Two and characteristic

 

1. The standard power distribution cabinet is used as the m--n cabinet, which controls the use of reasonable, small area, and beautiful appearance.

 

2. Control cabinet's device selection, installation, wiring and other strict accordance with the "electrical equipment safety design guidance", "insulation coordination of equipment in the low -voltage system", "the color of the wire in the set set of electronics" Design of relevant national standards such as rotation direction ".

 

3. The devices used are well -known brands at home and abroad, and the quality of the product is guaranteed.

 

4. Use the Delixor Soft promoter, and the 2.2KW motor as the control object to simulate the motor starting and get close to the industrial scene.

 

5. Provide various protection functions, which is safe and reliable in tr--ning.

 

3. Technical performance

 

1. Input voltage: three -phase and four lines (or three -phase and five lines) ~ 380V ± 10% 50Hz

 

2. Working environment: temperature -5 ℃ ～+40 ℃ relative humidity <85%(25 ℃) altitude <2000M

 

3. Device capacity: <7.5kva

 

Fourth, system equipment

 

The real tr--ning cabinet is m--nly composed of cabinets, electrical rooms, Delician soft starters, and three -phase asynchronous motors.
