Product Description: What are the protection devices for steam generators?The main protection devices for steam generators include safety valves, pressure gauges, and water level gauges.Safety ValveI. Types of Safety ValvesCommon safety valves used in industrial boilers can be categorized into three types based on the method of applying pressure to the valve core: dead-weight type, spring type, and lever type. Based on the lift height of the valve core during opening, they can be classified as low-lift type and full-lift type.If d is the throat diameter of the valve seat and h is the lift height of the valve core, when h ≥ (1/4)d, it is called a full-lift type; when h is between (1/40)d and (1/20)d, it is called a low-lift type.The outer diameter of the low-lift safety valve's core is the same as or slightly larger than the outer diameter of the valve seat sealing surface. When steam flows out, the upward thrust on the valve core is relatively small, resulting in a relatively rapid opening and closing action. This type is generally suitable for pressure relief of liquid media.Full-lift safety valves have a larger disc on the valve core. When steam flows out, it generates a greater upward thrust, allowing the valve core to lift significantly. This type of safety valve opens and closes more gently, has a large exhaust capacity, and good reseating performance, making it suitable for pressure relief of gas media.II. Models of Safety ValvesThe model, specifications, and parameters of safety valves mainly include the connection method, structural type, sealing material, valve body material, nominal pressure, and nominal diameter. For details, refer to the next section.For spring-type safety valves, due to the characteristics of the spring itself, the pressure range of each spring is limited. Therefore, a spring-type safety valve with a specific nominal pressure is equipped with springs of different pressure levels. Within a certain pressure level range, the safety valve can ensure a certain level of sensitivity. When selecting, it is necessary to choose the safety valve based on the required opening pressure for the steam generator's operating pressure and specify the spring's pressure level. The sealing pressure levels of commonly used spring-type safety valves for steam generators are shown in the table below. If no specific requirements are provided during purchase, they are generally supplied according to the PⅤ level. more>

Product Description: Requirements for Clean Rooms in Solid Preparation Facilities:The layout of the workshop shall comply with the following principles: rational floor plan according to the process flow; strict division of clean areas; prevention of contamination and cross-contamination; facilitation of production operations.Sampling of raw and auxiliary materials, as well as packaging materials that come into direct contact with pharmaceuticals, is one of the key aspects of product protection. Sampling should be conducted in a separate sampling area, where the air cleanliness level must match the production requirements. If sampling must be performed in the production area, a separate sampling room should be set up within the production area. This room should have direct exhaust ventilation, and the return air should not be recirculated.When rooms with high dust generation are relatively concentrated, a central dust collection system can be established for centralized dust removal. For workshops producing multiple products with frequent batch changes, rooms generating large amounts of dust should not use recirculated air if no purification measures are in place.The sampling environment for materials must match the cleanliness level of the production feeding area;lSeparate setup for personnel and material flows to prevent cross-contamination;Operating areas with high dust generation should maintain relative negative pressure. Exhaust air discharged outdoors must be purified and meet requirements, and the exhaust outlet should be far away from the air intakes of other air purification systems.Process Flow Diagram and Environmental Zoning Schematic for Wet Granulation Tablet ProductionGrade D Controlled AreaThe air cleanliness level of clean rooms (areas) for oral solid preparations should be controlled with reference to GMP Annex 1 Grade D for sterile pharmaceuticals.Cleanliness LevelMaximum Permissible Particle Count (particles/m3)Maximum Permissible Microbial Count0.5μm5μmAirborne Bacteria (CFU/m3)Settling Bacteria（φ90mm）cfu /4 hoursSurface Microorganisms(55mm)[CFU/plate]Grade D3,520,00029,00020010050lProduction areas prone to generating dust, such as the batching, granulation, and tableting processes of oral solid preparations, should maintain relative negative air pressure compared to adjacent rooms. Rooms for highly allergenic drugs like penicillin should maintain positive pressure and relative negative pressure compared to adjacent rooms.lAir purification should employ three-stage filtration with primary, medium, and high-efficiency filters. For Grade D air purification, sub-high-efficiency air filters may be used instead of high-efficiency filters.Local exhaust systems in clean rooms should be set up separately under the following circumstances:lClean rooms generating dust and harmful gases;lThe toxicity of the discharged medium is very high;lMixing of discharged media may exacerbate corrosion, increase toxicity, or cause combustion and hazards.Air Conditioning System Requirements for Oral Solid PreparationslDust-generating processes in multi-product production should not utilize return air. If return air is used, measures to prevent cross-contamination must be in place.lDust-generating rooms or points should be equipped with dust removal facilities, such as in weighing, crushing, screening, tableting, capsule filling, drying and granulation, and mixing processes.lThe operation of supply, return, and exhaust air systems should be interlocked. The system startup sequence should be: start the supply fan first, then the return and exhaust fans.lNon-unidirectional airflow organization may be used in controlled areas for oral solid preparations. The air change rate should be determined based on the dust generation level of the room. For example, rooms for crushing and screening, as well as rooms with high temperature and humidity, should have correspondingly higher air change rates.Relevant Standards:"Good Manufacturing Practice for Pharmaceuticals" 2010GB 50457-2019 Design Standard for Clean Rooms in Pharmaceutical IndustryGB 50073-2013 Design Code for Clean RoomsGB 51110-2015 Code for Construction and Quality Acceptance of Clean RoomsGB 50019-2015 Design Code for Heating, Ventilation, and Air Conditioning of Industrial BuildingsGB 50243-2016 Code for Construction Quality Acceptance of Ventilation and Air Conditioning WorksGB 50016—2014 (2018 Edition) Code for Fire Protection Design of Buildings more>

Product Description: During the growth of crops, various pests frequently occur, including thrips, grasshoppers, corn aphids, sugar beetles, beet armyworms, and others. Different crops are affected by different pests. To ensure healthy crop growth, it is essential to effectively monitor the types of pests. Based on detailed information obtained about pest conditions, a scientific control plan can be formulated to promptly and effectively manage various pests.In the past, when technology was less developed, pest conditions were determined through manual surveys, which was inefficient. With the continuous advancement of science and technology, people can now use IoT pest monitoring lamps to monitor crop pests.The Zhaodi IoT Smart Pest Monitoring Lamp converts solar energy into electricity during the day via solar panels and stores it in the internal battery. At night, leveraging the phototactic behavior of pests, the automatically lit lamp attracts pests from rice fields, cornfields, and vegetable plots. The pests are drawn to the light, collide with a transparent glass panel, and fall into a collection box.Infrared high-temperature treatment is used to kill the pests, ensuring a lethality rate as high as 98% while preserving the integrity of the pest bodies. Compatible with Zhaodi's pest monitoring and prevention system as well as the plant protection IoT system, it is equipped with a 20-megapixel industrial camera to remotely photograph pests and automatically transmit the images to the IoT terminal. The entire system operates automatically, enabling functions such as automatic pest killing, counting, and identification without human supervision.The IoT Smart Pest Monitoring Lamp has a wide range of applications and can be extensively used in agriculture, forestry, vegetable farming, tobacco, storage, brewing, gardens, orchards, urban greening, aquaculture, and more for the scientific control of pests and diseases. It can identify and monitor 1,287 pest species across 87 families, including cotton bollworms, scarab beetles, corn borers, fruit-piercing moths, and beet armyworms.Pest monitoring lamps enable technicians to detect pest occurrences early, allowing them to take scientific measures to effectively control and reduce the impact of pests on agricultural production.

Product Description: In agricultural production, soil moisture, which refers to the water content in the soil, is one of the key factors affecting crop growth. Changes in soil moisture directly relate to the soil's water retention capacity, crop water absorption, and the overall growing environment, thus having a profound impact on the growth and development of crops.First, suitable soil moisture is the foundation for normal crop growth. Crops absorb water and nutrients from the soil through their roots to support the growth and development of their above-ground parts. If soil moisture is insufficient, meaning the soil is too dry, crop roots will struggle to absorb enough water and nutrients, leading to stunted growth or even death due to water scarcity. Conversely, if soil moisture is excessive, meaning the soil is too wet, it can affect soil aeration, causing oxygen deficiency in the roots and similarly hindering normal crop growth.Second, changes in soil moisture also affect soil temperature. When soil moisture is moderate, the soil has a higher heat capacity, which helps stabilize soil temperature and provides a suitable growing environment for crops. However, if the soil is too dry or too wet, it can lead to significant fluctuations in soil temperature, which is unfavorable for crop growth. This is particularly evident under extreme climate conditions, such as drought or flooding, where changes in soil moisture have a more pronounced impact on crop growth.Additionally, changes in soil moisture affect soil fertility and microbial activity. When soil moisture is moderate, it promotes the reproduction and activity of soil microorganisms, facilitating the transformation and release of soil nutrients, thereby providing more nutrient support for crops. In contrast, overly dry or overly wet soil conditions can inhibit microbial activity, reduce soil fertility levels, and consequently affect crop growth.In summary, changes in soil moisture significantly impact crop growth. Therefore, in agricultural production, it is essential to closely monitor changes in soil moisture and regulate soil water conditions through appropriate measures such as irrigation and drainage to create a suitable growing environment for crops. At the same time, modern technological tools, such as soil moisture monitoring stations, can be utilized to monitor soil moisture conditions in real time, providing more precise and scientific management guidance for agricultural production. more>

Product Description: Wheat is one of the main grain crops in China, with a vast planting area in the northern regions. With the development of mechanization, wheat yields have been continuously increasing, but they are occasionally affected by wheat pests. So, what pests are commonly encountered during the growth of wheat? How can we monitor them to ensure the quality and yield of wheat cultivation?I. Common Pests1. Wheat AphidsWheat aphids are one of the common pests of wheat and are widely distributed, found almost everywhere across the country. During the growth process, they pierce and suck nutrients from wheat, affecting photosynthesis and nutrient absorption. After the wheat heads form, they concentrate on damaging the ears, resulting in unfilled grains. In severe cases, the ears turn dry and white, failing to produce seeds, and the entire plant may wither and die.2. Wheat MidgeThere are two main types of wheat midges in China: the red wheat midge and the yellow wheat midge. The red wheat midge primarily occurs along riverbanks in plain areas, while the yellow wheat midge is mainly found in plateau regions and high-altitude areas. Wheat midges are destructive pests whose larvae damage the flowers, seeds, or grains. The larvae hide inside the glumes and suck the sap from the filling grains, causing shriveled or empty husks.3. Wheat Spider MitesThere are two common types of wheat spider mites in China's wheat-producing areas: the long-legged wheat spider mite and the round wheat spider mite. Both types typically cause damage during the spring and autumn seasons. Infested wheat leaves develop white spots that later turn yellow. Mild symptoms result in stunted growth and dwarfed plants, while severe symptoms can lead to drying and death of the wheat.4. Wheat SawflyWheat sawflies mainly occur in areas north of the Huai River. The larvae damage wheat leaves by chewing from the edges inward, creating notches. In severe cases, they can completely devour the leaves. They only harm the leaves, and while feeding, their mouthparts cut the leaves into neat, piece-by-piece sections.5. Wheat WirewormThe larvae feed on sown seeds in the soil, consuming the endosperm and preventing germination. For already sprouted seedlings, they damage the fibrous roots, main roots, and stems, causing the plants to wither and die. This results in missing seedlings, broken rows, and even the destruction of entire fields.II. Monitoring SolutionsWith technological advancements, the monitoring and early warning of wheat pests have gradually shifted from traditional manual methods to intelligent device monitoring. In particular, the application of pest forecasting lamps in wheat pest monitoring has significantly improved the timeliness of pest forecasts and reduced the workload for staff.Staff can monitor pest types, quantities, and analyze pest development trends through smart agricultural cloud platforms on mobile phones or computers without needing to visit the field. This allows farmers to be notified in advance and take scientific control measures before pests spread widely, thereby enhancing the effectiveness of wheat pest management. more>

Product Description: The working principle of an explosion-proof dehumidifier mainly involves using a fan to draw moist air from the space into the dehumidifier, then passing it through a heat exchanger to condense the moisture in the air into water droplets, after which the now dried air is expelled from the unit. This repeated cycle achieves a reduction in indoor air humidity. The core working principle of the explosion-proof dehumidifier is the "circulation system," on which the operation and other functions of the dehumidifier are based. After the explosion-proof dehumidifier is turned on normally and the external circulation mode is activated, the fan begins initial operation, and moist air is drawn into the interior through the air inlet. The moisture (damp cold air) then passes through the device's evaporator, where the evaporator transfers the moisture in the air to the aluminum fins, turning it into dry air free of moisture. This dry air then passes through the device's condenser for heat dissipation and is finally transmitted to the outside through the air outlet. After the compressor operates, the exhaust port, via the fan, transfers the high-temperature and high-pressure gas from the space to the condenser for cooling. After cooling, the gas turns into a low-temperature, high-pressure gas, which then undergoes throttling treatment through the capillary tube, becoming a low-temperature, low-pressure liquid. It then evaporates and absorbs heat through the evaporator, and by the time it returns to the compressor, it has become a low-temperature, low-pressure gas, repeating the cycle through continuous operation. more>
