Why do many devices require use at altitudes not exceeding 1,000 meters? This post was last edited by brainandrain on 2009-3-14 08:22]
Typical equipment is designed under standard conditions, but at altitudes above 1000 meters, temperature and pressure change significantly; it is necessary to take into account the impact of these changes on the equipment.
Because the atmospheric pressure varies, it can affect the performance of the equipment
What was said upstairs is correct; pressure and temperature are important factors. When the equipment is at a high altitude, the airflow distribution also differs from that at lower altitudes. If a device is located within the area affected by typhoons, and its installation altitude is too high, then during typhoon or thunderstorm seasons, the high wind speeds generate significant shear stress on the device, which should be avoided as much as possible.
For every 100 meters increase in altitude, the temperature drops by 0.3 degrees; at 1,000 meters, it drops by 3 degrees! And the atmospheric pressure will also drop!
The mutual influence between atmospheric pressure and temperature! Many electronic and electrical devices are used in environments with pressures above 1000 M; as the temperature rises rapidly, these devices age more quickly, and their lifespan is significantly affected.
1 Excessive variations in external air pressure and differences from design parameters directly affect the performance of the equipment； 2. At high altitudes, the seasonal variations in external environmental conditions are extremely significant; these not only affect the performance of the equipment but also have a major impact on its safety ； 3. Under low pressure, the lubrication of equipment operation can be significantly affected. Therefore, equipment is generally required to be used at altitudes not exceeding 1000 meters when it leaves the factory; if it must be used at altitudes above 1000 meters, the manufacturer can be asked to design it specially during the ordering process
What was said upstairs is quite clear: the main consideration is the differences in physical properties, mass transfer, and heat transfer performance resulting from pressure changes
Equipment used in chemical applications is designed to operate under certain conditions, usually at atmospheric pressure. However, at altitudes above 1000 meters, the atmospheric pressure changes significantly. For example, some high-pressure equipment is designed for an atmospheric pressure of 1 atmosphere, but at high altitudes the pressure is lower; if such equipment is used at full capacity, an accident may occur due to the excessive pressure difference between the inside and outside
