Product Description: XJ Power FXL-11 Current Limiting ModuleXJ Power FXL-12 Current Limiting ModuleThe function of the charging monitoring module is to monitor the operating status of the rectifier modules. Depending on the configuration type of the rectifier modules in the power system, there are two models of charging monitoring modules available: FXL-11 and FXL-12. The FXL-11 charging monitoring module is used in conjunction with the ZZG12 series rectifier modules, while the FXL-12 charging monitoring module is used with the ZZG13 series rectifier modules.Basic Functions: ◇ The charging monitoring module connects to the centralized monitoring module of the power system via an RS485 interface. On one hand, it receives control commands from the upper-level monitoring system, controlling the output of the rectifier modules by adjusting the programmable output voltage (setting the equalizing/floating charge voltage) or by using relay output contacts to control the rectifier modules' power on/off. On the other hand, it uploads abnormal alarm signals from the rectifier modules, allowing the centralized monitoring module of the power system to perform corresponding alarm handling. ◇ The charging monitoring module monitors the charging and discharging current signals of the battery circuit and compares them with the charging current limit signal issued by the upper-level monitoring system. When the battery charging current is less than the given charging current limit value, the error amplification signal does not take effect, and the charging monitoring module controls the rectifier to operate according to the equalizing/floating charge voltage value issued by the upper-level monitoring system. When the battery charging current exceeds the given charging current limit value, the error amplification signal adjusts the programmable output voltage to change the equalizing/floating charge voltage value of the rectifier module, achieving automatic constant-current charging of the battery. ◇ The software watchdog continuously monitors the communication with the upper-level monitoring module. When communication between the charging monitoring module and the upper-level monitoring system is interrupted, the software watchdog enables the charging monitoring module to control the output of the rectifier module according to pre-set safe operating values, achieving automatic current-limited charging and normal floating charging of the battery. These measures prevent the risk of overcharging and damaging the battery due to communication interruptions during the equalizing charge state. Main Features: ◇ Utilizes a high-speed microcontroller system. Digital inputs, outputs, and communication interfaces are optically isolated, while analog inputs and outputs are isolated using linear optocouplers, with an isolation voltage of up to 3000Vdc. ◇ Employs a closed-loop PI regulation circuit for charging current, offering fast response, high current regulation accuracy, and strong anti-interference capability. Achieves true automatic constant-voltage and current-limited charging control for batteries. ◇ Stores critical system operation data. In the event of a centralized monitoring module failure, it automatically enters a safe mode to control the output of the rectifier module, ensuring normal battery charging voltage and current. ◇ As an essential control device in the power monitoring system, the charging monitoring module operates in a series hot-standby configuration with the centralized monitoring module. Its normal operation or failure does not affect the overall system performance. ◇ Features a modular structural design, enabling convenient and rapid system integration. more>

Product Description: Herzberg Filtration Speed Tester LSY-1Product Model: LSY-1Application Scope: The Herzberg filtration speed tester, filtration speed tester, and filtration velocity measuring instrument are primarily used to determine the water filtration speed of filter paper and filter board with certain wet strength. It is an ideal testing equipment for paper manufacturing enterprises, paper-using industries, quality inspection departments, university laboratories, etc.Product Use: This instrument is suitable for measuring the water filtration speed of filter paper and filter board with certain wet strength, but it cannot be used for filter paper and filter board that have been resin-treated or have non-hydrophilic or incompletely hydrophilic surfaces. The working principle of the instrument is to measure the time required for 100 ml or 200 ml of water to pass through a paper sample with a diameter of 35.7 mm (area 10 cm²) under a pressure difference of 1 kPa (i.e., 100 mm water column) on both sides of the sample. The time is expressed in seconds. Water quality requirements: At 20°C, the water should meet the conductivity of (3.2-4.4) × 10⁷ ms/m tap water or 0.02% NaCl distilled or deionized water, filtered through a 0.8 µm membrane or equivalent filter paper, and treated with heating or vacuum degassing.Technical Specifications:Sample Thickness Range: 0.10–3.00 mmTest Area: 10 ± 0.05 cm²Clamping Ring Inner Diameter: Ø35.7 mmClamping Ring Outer Diameter: Ø50 mmOverall Dimensions: 330 × 400 × 920 (mm)Weight: Approximately 18 kgInstrument Structure:1. The instrument consists of a container, clamping ring, measuring cylinder, and electronic control box.2. The upper part of the container is equipped with an air vent valve and a constant pressure tube (funnel) with a funnel. The bottom of the container has a connector, which is connected to the solenoid valve via a tube.3. The clamping ring consists of an upper pressure ring, lower pressure ring, bracket, and water collection box. The upper pressure ring is connected to the adjustment screw on the crossbeam. For easy sample installation, the column can rotate on the crossbeam. After the upper pressure ring is rotated out of the center, the sample is installed. Below the lower pressure ring is a water collection box. When replacing the sample, residual water on the lower pressure ring flows into the water collection box and then drains out through the leak pipe below the water collection box.4. There is a connector at the bottom of the lower pressure ring, which is connected to the solenoid valve via a tube. When the solenoid valve is energized, water from the container flows from the bottom through the solenoid valve into the clamping ring. Water passing through the paper sample flows into the measuring cylinder via the permeable tube of the upper clamping ring.5. The measuring cylinder consists of an electric measuring head, cylinder stand, and drain valve. Water passing through the sample flows into the measuring cylinder via the upper pressure ring. When the water level in the cylinder rises to the zero position, the electric measurement system starts timing. When the filtered water reaches the 100 ml electric measuring head, timing stops. The 100 ml or 200 ml range switch is located on the front panel. After completing a test, open the drain valve, and the water level in the measuring cylinder drops. When it returns to the zero position, the display resets to zero.6. The electric measurement system consists of an electric measuring head, display buttons, etc., and uses a single-chip microcomputer-based measurement and control system for operation. The power switch is located on the front panel of the electronic control box.Standard Configuration: Main UnitCompliance Standards: GB 10340-89 (Reference Standard GB 450)National Standard: GB/T 10340 more>

Product Description: Fully Automatic Mortar Vertical Expansion Rate TesterAutomatic Collection and Calculation of Mortar Expansion RateVertical Expansion Rate of Expansion Mortar for GroutingDeterminationSelf-Compacting Concrete TesterDigital Display Grouting Mortar Vertical Expansion Rate Tester for Concrete MortarI. Equipment IntroductionThe concrete cement mortar vertical expansion rate testing instrument for grouting is based on the national standard GB50119-2013 "Design Code for Application of Concrete Admixtures." This code applies to the use of fourteen types of admixtures in concrete engineering, including ordinary water reducers, high-range water reducers, air-entraining agents, air-entraining water reducers, retarders, retarding water reducers, retarding high-range water reducers, accelerators, accelerating water reducers, antifreeze agents, expansion agents, pumping agents, waterproofing agents, and flash-setting agents. This testing method is suitable for determining the vertical expansion rate of expansion mortar used for grouting.II. Main Technical Parameters1. Testing instruments and tools shall comply with the following specifications:2. Dial indicator: Range 0-10mm;3. Glass plate: Length 140mm x Width 80mm x Thickness 5mm;4. Steel pressure block: Diameter: 70mm, Thickness: 5mm, Mass: 150g;5. Test mold: 10mm x 10mm x 10mm cube test mold, assembly seams shall be filled with butter to prevent water leakage;6. Scoop: Width 60mm, Length 160mm;7. Tamping rod: Can be replaced with a steel saw blade;III. Installation:1. Steel base plate: The surface should be flat and placed horizontally on the workbench, with a levelness not exceeding 0.02;2. Test mold: Place on the steel base block without shaking;3. Glass plate: Place flat in the center of the test mold, leaving a 10mm gap on both sides between the plate and the inner edge of the test mold;4. Digital dial indicator and dial gauge should be securely fixed to the gauge stand clamp, but the gauge rod should be able to move freely up and down. When installing the dial gauge, press down the gauge head, ensuring it is not tilted forward, backward, or sideways;5. Fix the dial indicator stand to the steel base plate, as close to the test mold as possible to shorten the cantilever length of the horizontal rod.IV. TestSteps:1. The water content for the grouting material should be based on the water amount required for a flowability of 250±10mm.2. After mixing the grouting material with water uniformly, immediately pour it into the mold from one side of the glass plate. When the height reaches about 50mm, use the tamping rod to poke 6 times on each side of the test mold and 6 times in the center. When the height reaches 90mm, repeat the poking process as before to expel air as much as possible. The final layer of grouting material should be poured in one go until it flows out from both sides. Minimize the upward buoyant force exerted by the grouting material on the glass plate.3. On both sides of the glass plate, gently shape the surface of the grouting material into a slope using a small knife, with the high edge level with the glass and the low edge level with the top inner surface of the test mold. The time for shaping the slope should not exceed 30 seconds. Within 30 seconds after that, cover the grouting material surfaces on both sides of the glass plate with two layers of wet cotton cloth.4. Place the steel pressure block in the center of the glass plate, then lower the dial indicator measuring head onto the steel pressure block. Record the dial indicator reading h0 within 30 seconds to establish the initial reading.5. Starting from the initial reading, water once every 2 hours. Water continuously 4 times. After that, water once every 4 hours. Maintain moist curing until the required age, and measure the height readings of the specimens at 3 days and 7 days. more>
