Working environment conditions of explosion-proof bridge crane
Indoor and outdoor working environment requirements
For indoor working environments, in addition to ensuring good ventilation and lighting conditions, the concentration of explosive gases or vapors needs to be regularly tested and cleaned up to avoid any potential risk of explosion. At the same time, the building structure of the workshop or plant should have sufficient strength and stability to withstand the impact and pressure of explosive gases or vapors. In addition, the indoor environment should be kept relatively dry to prevent problems such as corrosion and electrical short circuits. Compared with the indoor environment, the outdoor working environment is more complex and variable. When used outdoors, explosion-proof overhead cranes need to withstand the influence of various natural factors, such as wind load, rain load, snow load, solar radiation and so on. In order to ensure the stability and safety of the crane, these natural factors must be fully considered and evaluated. For example, in terms of wind load, cranes should have sufficient wind resistance to avoid structural damage or overturning due to strong winds. In terms of rain load, cranes should have waterproof sealing performance to prevent rainwater from intruding into the electrical system or causing structural damage. In addition, for factors such as snow load and solar radiation, cranes should have cold and heat resistance to adapt to temperature changes in the outdoor environment.
Temperature and humidity conditions
Temperature and humidity are important factors affecting the safety performance of explosion-proof overhead cranes. For the normal operation and safety of explosion-proof overhead cranes, the temperature and humidity of the environment in which they are located need to be controlled within the appropriate range. Excessive temperature may lead to overheating or damage to the crane electrical system. In a high temperature environment, the insulation of electrical equipment decreases, which can easily lead to safety accidents such as electrical short circuit or fire. In addition, high temperature may also make the lubricant thin, affecting the lubrication effect of the crane and accelerating the wear and tear of mechanical parts. On the other hand, excessive humidity is also detrimental to the operation of explosion-proof overhead cranes. In a humid environment, electrical equipment is susceptible to moisture erosion, which may lead to problems such as insulation degradation and circuit failure. In addition, excessive humidity may also trigger corrosion problems, causing damage to the structural components and connection parts of the crane. In order to ensure the normal operation and safety of explosion-proof overhead cranes, it is necessary to set a reasonable range of temperature and humidity according to its specific model and use environment. In the high temperature environment, cooling measures should be taken such as increasing ventilation, setting sunshade facilities, etc.; in the humid environment, moisture-proof measures should be taken such as increasing drying equipment, strengthening the sealing and so on. At the same time, it is also necessary to regularly check and maintain the status of the crane electrical system and structural components to ensure their normal operation and safe use.
Altitude and air pressure restrictions
Altitude and air pressure also have a certain impact on the performance and service life of explosion-proof overhead cranes. As the altitude increases the atmospheric pressure and oxygen content gradually reduces and may lead to crane electrical system performance degradation or failure. High altitude climate and environmental conditions are often more severe, such as thin air, wind, low temperature, etc., these factors may have an adverse effect on the normal operation of explosion-proof overhead travelling crane. In order to ensure the normal use of cranes in high-altitude areas, it is first necessary to fully investigate and analyze the local geographic environment and climatic conditions. According to the actual situation in high-altitude areas, the crane's electrical system, lubrication system, cooling system and other corresponding adjustment and optimization. For example, strengthen the insulation of the electrical system to reduce the working load and other measures to adapt to the special environmental conditions of high-altitude areas. In addition, the use of explosion-proof overhead cranes at high altitude also need to pay attention to strengthen the inspection and maintenance of equipment to ensure that the equipment is always in good operating condition at the same time, but also pay attention to the operator's training and safety education to improve the skill level of the operator and safety awareness to ensure the use of explosion-proof overhead cranes at high altitude areas of safety and reliability!
