Product Description: NB-IoT Smart Water MeterGuang'an IoT water meter is a dry-type water meter that utilizes photoelectric direct reading technology and NB-IoT network for remote data transmission; it features high measurement accuracy, high reading conversion accuracy, and stable data transmission.Product Overview:NB-IoT Smart Water Meter is a dry-type water meter that uses photoelectric direct reading technology and NB-IoT network for remote data transmission; it features high measurement accuracy, high reading conversion accuracy, and stable data transmission.Guang'an IoT Water Meter Product Features: NB-IoT Smart Water MeterUtilizes NB-IoT communication technology, featuring ultra-low power consumption, ultra-high sensitivity, wide signal coverage, strong penetration capability, high stability, and secure and reliable data transmission. The installation of the water meter is the same as that of a regular water meter, eliminating the need for construction wiring, thereby reducing installation costs;The antenna adopts a built-in structure, minimizing the risk of damage during construction;Employs photoelectric direct reading technology, ensuring accurate data without cumulative errors, achieving high meter reading accuracy;The entire electronic control unit is fully sealed, allowing use in harsh environments;Dry-type, multi-jet eccentric structure, offering high sensitivity, wide measurement range, and stable and reliable metering; strong resistance to external magnetic interference, with the impeller magnetic ring having high pollution resistance;Guang'an IoT Water Meter can be equipped with a highly reliable built-in valve, enabling remote forced opening and closing of the valve, providing water supply management departments with a tool for fee collection and management.When selecting specifications, first estimate the typical flow rate and flow range, then choose the water meter specification that matches the commonly used flow value. This is because the water meter's performance stability and durability are optimal under commonly used flow conditions, aligning with design requirements. If the pipeline is designed with future water capacity in mind, a water meter with a caliber one size smaller can be selected. For example, if a 200mm diameter pipeline currently has insufficient flow, a 150mm diameter water meter can be installed. When the flow increases to the normal level for a 200mm pipeline in the future, a water meter of the same caliber can be replaced. For large industrial water consumers, one larger caliber water meter can be selected, or multiple smaller caliber water meters can be used in parallel. This approach also allows for maintenance or replacement of individual faulty water meters without affecting the user's normal water supply. more>

Category: Machinery & Equipment/Electric Heating Equipment/Medium Frequency Power Supplies

Company: 河北保菲新材料有限公司

Product Description: Performance Aspects · Dimensional and Shape Stability: Pellets can maintain their original size and shape under high temperatures without significant expansion, contraction, deformation, or fragmentation due to thermal stress and other factors. For example, in the blast furnace ironmaking process, if pellets have poor thermal stability, they may break into small pieces or powder in the high-temperature zones of the furnace, affecting the permeability of the furnace burden column and the smooth operation of the furnace. · Strength Stability: Pellets can maintain a certain mechanical strength in high-temperature environments without experiencing a sharp decline in strength. Sufficient strength is necessary to withstand the pressure from the upper burden in the blast furnace and the forces from rising gas, preventing pellets from breaking due to collision and compression during transportation, charging, and smelting. · Chemical Stability: The chemical composition of pellets remains stable under high temperatures, without excessive oxidation, reduction, decomposition, or other chemical reactions, to avoid affecting pellet performance and subsequent ironmaking processes. For instance, iron oxides in certain pellets should undergo reduction according to the expected reaction pathway at high temperatures, rather than abnormal reactions that alter pellet properties. Importance · Ensuring Blast Furnace Permeability: Pellets with good thermal stability can remain intact in the blast furnace, maintaining reasonable gaps between the burden materials, allowing gas to pass through the burden column evenly and smoothly. This facilitates good gas-solid mass and heat transfer processes, improving blast furnace production efficiency and gas utilization. · Maintaining Blast Furnace Operational Stability: Stable pellets enable more uniform burden flow and temperature distribution within the blast furnace, reducing fluctuations in furnace conditions caused by pellet breakage and pulverization. This lowers the probability of abnormal situations such as furnace wall erosion and channeling, ensuring stable blast furnace operation and extending its service life. · Improving Ironmaking Quality and Output: Good thermal stability of pellets ensures that reduction and other reactions proceed according to the predetermined mechanisms in the blast furnace, making the iron reduction process smoother and more efficient. This helps improve the quality and output of molten iron while reducing energy consumption and production costs. Influencing Factors · Raw Material Characteristics: The type, particle size distribution, and chemical composition of the ore powder can affect the thermal stability of pellets. For example, impurities and moisture content in the ore powder, if too high, may have adverse effects during heating. · Binder Usage: The type, dosage, and performance of binders are crucial for pellet thermal stability. Suitable binders can form strong bonds between pellet particles, enhancing thermal stability; conversely, improper binder selection or insufficient dosage can lead to issues such as pellet breakage under high temperatures. · Production Processes: These include pelletizing, drying, and roasting processes. For instance, improper control of roasting temperature and time may result in insufficient or excessive roasting, affecting the crystal structure and strength of pellets, thereby reducing thermal stability. more>
