Turn on the turntable extraction tower experimental device

1. Understand the structure of the turntable extraction tower.

2. Master the measurement method of the performance of the turntable extraction tower.

3. Understand the reinforcement method for the efficiency of the transmission of the rotor to extract tower.

4. Observe the changes and flow status in the tower during different speed.

5. Fixed two -phase traffic, determine the number of mass transmission units of the extraction tower at different speeds, HOE, and total transmission coefficient Kyea.

2. Equipment characteristics:

1. The entire device is beautiful, the structure is reasonable, and the overall sense is strong, which can fully reflect the concept of modern experimental devices.

2. The equipment is a self -propelled frame structure, and the feet are installed to facilitate the disassembly m--ntenance and handling of the system.

3. Except for special materials, the entire equipment is made of industrial 304 st--nless steel. All equipment is finely polished, which reflects the perfectness of the entire device.

4. The tower festival is made of high -quality inorganic glass, which has good visual effects, which is convenient for students to observe.

5. The tower components and pipelines are made of 304 st--nless steel.

6. Device design can be observed at 360 degrees to achieve comprehensive teaching and experiments.

7. Three -purpose table simulation software: This software is the format of the APK, which can be used on the PC side, or it can also be used on the mobile terminal. When using a multi -meter, the black smoke prompts and can reset the multi -meter), the polar judgment of the transistor, the DC voltage measurement (the light is bright at the current meter file), the measurement of the DC current, and the judgment of the capacitance. This software can be dragged arbitrarily red and black pen heads. Two pen heads are dragged to the red circle when the target is located. The measured data error, etc.), the instrument pointer will be re -measured without response, prompt error, etc. Clearly watch the size of the test data. Students can learn the correct use of multiple tables through this software. Provide demo and copyright certificates.
