Product Description: High-Temperature Rubber Sealing Ring Resistant to 250°C for Industrial EquipmentThermal Stability of High-Temperature Rubber Sealing Ring Resistant to 250°C? DshfmcomIn the field of sealing for high-temperature industrial equipment, the thermal stability of rubber sealing rings directly determines the operational safety and maintenance cycle of the equipment. Based on the latest industry research data, this article systematically analyzes the material characteristics, thermal aging mechanisms, and performance optimization solutions of rubber sealing rings resistant to 250°C, providing technical reference for the selection of sealing systems in high-temperature working conditions.I. Material Characteristics of High-Temperature Rubber Sealing RingsRubber sealing rings resistant to 250°C primarily use two types of specialty materials: fluorosilicone rubber (FVMQ) and fluoroelastomer (FKM). Fluorosilicone rubber sealing rings exhibit a compression set of only 29% in tests at 175°C for 22 hours, with their unique siloxane bond structure enabling the material to maintain elasticity within the range of -60°C to 250°C. In comparison, fluoroelastomer sealing rings can withstand temperatures up to 300°C but perform poorly at low temperatures (prone to brittleness below -20°C). Experiments have shown that fluoroelastomer sealing rings with 25% carbon fiber additive retain a tensile strength retention rate of 68% after 1000 hours of continuous operation at 250°C, far exceeding the 15% of ordinary nitrile rubber.II. Thermal Aging Mechanisms and Performance DegradationThe aging of rubber sealing rings in high-temperature environments is essentially a competitive process between oxidative chain scission and cross-linking reactions of molecular chains. After 70 hours of thermal aging in air at 250°C, fluoroelastomer sealing rings experience a hardness increase of 6 points and a 31% decrease in tensile strength, resulting from the oxidative cleavage of fluorocarbon bonds. Notably, dynamic sealing conditions accelerate thermal aging—under the same temperature, the lifespan of sealing rings subjected to 10% compression deformation is 40% shorter than that in a free state. Infrared spectroscopy analysis reveals that a dense SiO₂ oxide layer forms on the surface of fluorosilicone rubber sealing rings, which is key to their superior heat resistance compared to ordinary rubber.III. Performance Enhancement Technical PathwaysThe core of improving the thermal stability of rubber sealing rings lies in material modification:· Nano-zinc oxide filling increases the thermal conductivity of fluoroelastomer sealing rings by 200%, effectively reducing the risk of local overheating.·Layered composite structure design (fluoroelastomer outer layer + silicone rubber inner layer) balances heat resistance and elasticity, improving the uniformity of sealing contact pressure distribution by 45%.· Surface coating with diamond-like carbon film can control the friction coefficient below 0.1, reducing heat generation.IV. Selection and Application RecommendationsFor extreme working conditions above 250°C, the use of metal-reinforced rubber sealing rings is recommended, as they can withstand extrusion pressures up to 45 MPa. In acidic media, fluoroelastomer sealing rings should be used with PTFE anti-extrusion rings, extending corrosion-resistant lifespan by three times. The latest industry standards require that high-temperature rubber sealing rings must pass a 200°C × 500h accelerated aging test before leaving the factory, with hardness changes not exceeding ±10%.Dongsheng Seals was established in 1992. Over 32 years, it has focused on technological innovation in sealing, forming a doctoral team of over 10 members, creating an industry-leading testing center, and equipping itself with internationally advanced production equipment.

Product Description:        Medium to large tubular conveyor ore powder electric tubular elevator, screw conveyor is suitable for non-viscous dry powder materials and small granular materials.(For example: cement, fly ash, lime, grain, etc.) whileshaftless screw conveyoris suitable for conveying viscous and easily entangledScrew conveyors are divided into two types in terms of conveying form: shaft screw conveyor and shaftless screw conveyor. In terms of appearance, they are divided intoU-type screw conveyor and tubular screwconveyor. Shafted materials. (For example: sludge, biomass, garbage, etc.) The working principle of the screw conveyor is that the rotating spiral blades push thematerialto move for screw conveyor conveying. The force that prevents the material from rotating with the screw conveyor blades is the weight of the material itself and the frictional resistance of the screw conveyor casing to the material. The spiral blades welded on the rotating shaft of the screw conveyor have different blade surface types according to the material being conveyed, including solid surface type, belt surface type, blade surface type, etc. The screw shaft of the screw conveyor has a thrust bearing at the end of the material movement direction to withstand the axial reaction force of the material on the screw. When the machine is long, intermediate hanging bearings should be added.       When the material is added to the fixed chute, due to the gravity of the material and the friction between the material and the chute, the material accumulated in the lower part of the chute does not rotate with the screw body, but only moves forward under the push of the rotating spiral blades, just like a non-rotating nut moving translationally along a rotating screw, achieving the purpose of conveying materials. This machine is convenient for multi-point loading and unloading, and can simultaneously complete mixing, stirring or cooling functions during the conveying process. It is sensitive to overload and prone to clogging; it has crushing loss to materials. The horizontal screw conveyor has a simple structure, making it easy to install, maintain and handle faults. It is suitable for horizontal or slightly inclined (20ºbelow) continuous and uniform conveying of loose materials. The working environment temperature is-20—+40℃, and the material temperature is-20—+80℃. Its speed is relatively lower than that of vertical conveyors. It is mainly used for horizontal or small inclination angle material conveying, and the conveying distance is generally not more than70meters.Medium to large tubular conveyor ore powder electric tubular elevator. more>

Product Description: Low-Temperature Air-Cooled Units for Scientific ResearchLow-temperature air-cooled units for scientific research are air-cooled refrigeration equipment designed to provide cold sources ranging from -5°C to -40°C for research experiments. At specific temperatures, researchers can read physical data from experiments. The temperature range of the low-temperature air-cooled units introduced by our company is as follows: the new natural air can reach a low temperature of -40°C, operating continuously 24 hours a day; the cold air can reach a low temperature of -90°C, operating continuously 24 hours a day.Working PrincipleAccording to the principle of the refrigeration system: low-temperature, low-pressure liquid refrigerant undergoes heat exchange with the air flowing into the evaporator. The evaporator absorbs heat from the air, and during the evaporation process, the refrigerant temperature remains unchanged. The liquid refrigerant evaporates into a low-temperature, low-pressure gaseous refrigerant and enters the compressor. After being compressed by the compressor, it becomes a high-temperature, high-pressure gaseous refrigerant and then enters the condenser. In the condenser, it undergoes heat exchange with the natural air drawn in by the cooling fan, discharging the heat of the high-temperature, high-pressure refrigerant out of the unit. The refrigerant then flows out of the condenser through a dryer filter, which removes moisture or other impurities from the refrigerant during the evaporation process. It then enters the expansion valve for expansion and throttling, a process that rapidly lowers the temperature, turning the refrigerant into a low-temperature, low-pressure liquid. The refrigerant after this process re-enters the evaporator for heat exchange and evaporation, thereby completing the entire refrigeration system cycle. This cycle continues continuously, allowing for sustained refrigeration. The cold air is then delivered to the desired cooling destination through the fan via the air outlet.Unit Selection12.

Product Description: With the continuous development of modern agriculture, pest control has become an indispensable part of agricultural production. As an efficient pest monitoring tool, pest forecasting lamps play an increasingly important role in agricultural production. So, how many acres is it appropriate to use one pest forecasting lamp? This article will explore this issue.First, we need to understand the basic principles and application scenarios of pest forecasting lamps. Pest forecasting lamps simulate natural light sources to attract pests, using factors such as light source, spectrum, and light intensity to trap pests, thereby achieving real-time monitoring of field pests. Pest forecasting lamps are widely used in pest monitoring and control in orchards, forestry, grasslands, and other areas, which is of great significance for improving control effectiveness and protecting the ecological environment.In terms of field pest monitoring, pest forecasting lamps can cover a large area. Generally, one set of pest forecasting lamps can cover an area of about 20 to 100 acres in plain regions. However, the actual monitoring area is influenced by various factors, such as equipment performance, terrain, and vegetation type. Therefore, when determining the coverage range of pest forecasting lamps, these factors need to be considered comprehensively.For areas such as orchards, forestry, and grasslands, the coverage range of pest forecasting lamps will also vary. In orchards, due to the dense distribution of fruit trees and relatively limited pest species, one pest forecasting lamp can cover a smaller area, such as 10 to 20 acres. In forestry and grassland areas, due to the diversity of vegetation types, complex terrain, and richer pest species, one pest forecasting lamp can cover a larger area, such as 30 to 50 acres.In practical applications, the following measures can be taken to improve the monitoring effectiveness of pest forecasting lamps: first, reasonably arrange the position and quantity of pest forecasting lamps based on factors such as terrain and vegetation type; second, regularly inspect and maintain pest forecasting lamps to ensure their normal operation; third, combine other pest monitoring methods, such as manual surveys and natural enemy investigations, to comprehensively analyze pest occurrence and develop scientific control plans.In summary, pest forecasting lamps play a crucial role in field pest monitoring and control. When determining the coverage range of pest forecasting lamps, various factors such as equipment performance, terrain, and vegetation type need to be considered comprehensively. By optimizing the layout and management of pest forecasting lamps, pest monitoring effectiveness can be improved, providing strong support for agricultural production. more>
