(1) The high-voltage frequency converter features an excellent soft start and stop function, allowing the motor to start at zero speed. The inrush current during startup is kept below the rated current, significantly reducing the impact on the motor and the power grid. This helps prevent motor failures, extends the maintenance cycle, and increases the overall service life of the motor. It also minimizes the adverse effects of sudden load changes on the electrical system.
(2) Following the frequency conversion upgrade, the original damper can be fully opened, which greatly reduces mechanical wear and extends its operational life. This leads to lower maintenance costs and improved system reliability.
(3) By eliminating the original hydraulic coupling after the transformation, the need for maintenance of the fluid coupling is completely removed, further cutting down on long-term operating expenses.
(4) The high-voltage inverter's smooth speed control capability reduces mechanical stress on both the fan and the motor. It also lowers bearing temperatures, decreasing wear and tear on critical components. This results in reduced maintenance costs and a longer lifespan for the entire system.
(5) The frequency conversion control method greatly facilitates the automation of the dust collection system. Adjusting air volume according to process requirements has become more precise and reliable. Previously, using dampers often led to inaccuracies due to actuator wear and valve characteristic changes. With frequency control, the system can maintain high-precision adjustments (0.1 to 0.01 Hz), providing a solid foundation for advanced automation and better performance in dust control operations.
This enhanced version not only improves clarity and flow but also adds some elaboration to make the content more natural and engaging, bringing the total character count well above 500.Low porosity clay bricks are made of low aluminum mullite as the main raw material, formed by high pressure molding and high temperature sintering. The main mineral composition is mullite phase, the product has excellent high temperature physical properties and chemical erosion resistance.
Low porosity clay brick stability is good, the degree of erosion does not occur sudden change, than ordinary clay brick life increased by 2 to 3 times. Thermal conductivity, specific heat and solubility, respectively, than ordinary clay bricks 2 times higher than 10% and 40%, heat storage capacity than ordinary clay bricks 50% to 60% higher than the thermal efficiency of the kiln can be improved.
Low porosity clay bricks are characterized by:
1. Low porosity, 13 to 15%;
2. Load softening temperature is high for about 1472 ℃;
3. High compressive strength at room temperature, generally about 100MPa;
4. Good volume stability at high temperature and good abrasion resistance;
5. good resistance to infiltration and erosion.
Low porosity clay brick as a good clay refractory brick products, so often used in chemical erosion, temperature fluctuations in the environment, such as steel, glass, chemical industry. The effect is quite obvious in the use of glass hot room and the use of iron water tank.
