Lucky ratio blocking test device

The sludge ratio (or ratio impedance) is a comprehensive indicator of sludge dehydration performance. The greater the sludge than the resistance, the worse the dehydration performance, and the better the dehydration performance. The ratio of the active sludge in this experiment is tested with FeCl3 and AL2 (SO4) 3 as a concrete.

I hope to achieve the following goals through experiments:

1 Master the experimental method of determining sludge ratio;

2 Master the choice of concrete with a British funnel test;

3 Master the method of determining the coagulant.

2. M--n technical indicators and parameters:

1. Environmental temperature: 5 ℃ ～ 40 ℃

2. The measuring cylinder 300ml,

2. Dimensions of the filter tube: 筒150 × 250 mm,

3. Total size of the device: 700mm × 400mm × 1200mm,

4. Work power: AC220V ± 10%, 50Hz, single -phase three -line system, power 200W, safety protection: ground protection, leakage protection, overcurrent protection

Overview

 

This device is the micro -shrinking of the actual flat two -dimensional motion system. It is controlled by a programmable controller. In the direction of the X and Y axis, it accurately drives the stepping motor to perform the finished product control. All the action processes in the system.

 

Technical Parameters

 

Power: single phase AC220V, 50Hz

Power: <200W

Equipment structure:

 

The cross -sliding control tr--ning model is a metal structure, and the connection terminals of each commonly used module are connected to the safe socket, and the circuit is connected to the circuit with a wire with a safe plug; connect. The combination of the plug -in connection circuit with the terminal connection circuit not only ensures the tr--ning, formation and consolidation of the basic skills of students, but also to ensure the rapid, safe and reliable circuit connection.

3. Equipment characteristics:

1. Manual/automatic control mode, for hardware detection and programming.

2. Open execution agencies can be programmed according to different control schemes to form different execution systems, and adapt to personnel at different levels to learn and program. It can also be used as a subject design or research.

3. The product is open, and the overall mechanical structure is clearly visible.
