What problems does the matrix-type high-precision belt scale solve in the coal conveyance measurement of power plants?

Coal conveyance measurement in power plants is a crucial link for ensuring the stable operation of the power generation process and serves as an important basis for economic accounting and energy consumption statistics in power plants.

Traditional belt scales often fail to meet the requirements of high flow rates, high precision, and long-term stability, presenting various issues in coal conveyance measurement. The matrix-type high-precision belt scale, as an advanced new type of belt scale, can address a series of problems in coal conveyance measurement at power plants.

The main issues in coal conveyance measurement at power plants include:

1. The measurement accuracy of traditional belt scales is limited, making it difficult to meet the high-precision requirements for fuel measurement in modern power plants.

2. The long-term stability of belt scales is insufficient. Even if the accuracy requirements are initially met, it is challenging to maintain them over the long term, as they are easily affected by various factors in the coal conveyance system, such as uneven coal flow, significant changes in conveyor belt tension, electromagnetic interference in the environment, and coal dust accumulation.

3. The durability is limited, failing to meet the demands of continuous, uninterrupted, and high-flow-rate coal conveyance measurement in power plants.

4. The maintenance and repair costs of belt scales are high, requiring frequent calibration, repairs, daily cleaning of the scale frame, and even causing disruptions to production operations.

The matrix-type high-precision belt scale, with its excellent performance, rich features, advanced technology, novel structure, and design philosophy, resolves the aforementioned issues in coal conveyance measurement at power plants:

1. High-precision measurement: The matrix-type belt scale adopts a new design philosophy, altering the scale frame structure. The weighing units are arranged and combined according to a mathematical model rather than being connected by mechanical levers or beams, eliminating the impact of mechanical components, self-weight, force transmission, and fulcrums on measurement.

Advanced weighing sensors and digital signal processing technology enable high-precision measurement of material weight and lossless signal transmission. Belt tension is mutually canceled out among the weighing units, reducing the impact of belt tension on measurement. Practical applications have shown that this belt scale can achieve a measurement accuracy of 0.25% when properly installed and adjusted.

2. Enhanced stability: Through the matrix-type weighing model, the load on individual weighing modules is effectively reduced. The weighing modules are independent of each other; if one module or weighing sensor fails or is damaged and cannot operate, the others continue to function normally, improving stability.

Automatic adjustment and tracking compensation adjust the interval values and zero points, significantly suppressing the influence of various environmental factors during long-term operation. Applications in power plants have proven that this belt scale can maintain long-term stable measurement performance under various operating conditions.

3. Reduced maintenance costs: The matrix-type belt scale features a modular design, facilitating quick replacement and repair. If precision requirements change, the accuracy can be improved by simply adding weighing units without replacing the entire belt scale measurement system, reducing equipment replacement costs.

The minimalist scale frame structure almost eliminates issues such as coal dust accumulation, coal jamming in the idlers or scale frame, and daily cleaning and maintenance work are virtually unnecessary. Self-monitoring sensors and the entire belt scale measurement operation can instantly alert to anomalies, intelligently providing the cause, location, and recommendations for faults, enabling rapid problem resolution.

4. High-flow-rate measurement capability: The overall measurement capability is significantly enhanced, meeting the demands of continuous, high-flow-rate, and uninterrupted coal conveyance measurement in power plants.

In summary, the matrix-type high-precision belt scale plays a crucial role in coal conveyance measurement at power plants, resolving numerous issues faced by traditional belt scales. It can be employed in scenarios where traditional belt scales fail to meet requirements.
