Extreme environments
Extreme environments
Extreme environments (high temperature, low temperature, high altitude, high humidity, strong radiation, desert/polar regions, etc.) pose core challenges to the project’s equipment stability, personnel safety, and construction efficiency. Lvma Electric provides a full range of solutions, focusing on the principle of “environmental adaptation + risk pre-positioning + dynamic guarantee”, and building a system from the four dimensions of planning, technology, execution and emergency response.
In source selection, high-temperature-resistant materials and components are given priority, and civilian-grade components are not allowed to be used in high-temperature scenarios.
Structure and heat dissipation optimization, such as adding heat dissipation channels and using efficient heat dissipation modules to reduce high temperature accumulation.
Full process verification, through high temperature constant temperature test, temperature cycle test, high temperature aging test, to expose potential faults in advance.
For material and component selection, choose low-temperature resistant materials and use wide-temperature range electronic components.
Structural and protective design, insulating core components, optimizing sealing to prevent condensation and freezing.
Low-temperature verification and adaptation, through low-temperature constant temperature test, low-temperature start-up test, and temperature cycle test, expose faults in advance and optimize them.
High altitude environment product reliability solutions, the core for low pressure, strong ultraviolet light, temperature difference, energy shortage four big problems. Heat dissipation using“Heat sink + heat pipe”, altitude per liter of 1000 meters power volume reduction of 5%-15% , 10%-15% increase in the electrical gap insulation end, the use of epoxy and other high-quality insulation materials; UV resistant alloy, weather resistant rubber and wide temperature range electronic component are preferred, which are verified by laboratory simulation and high altitude field test to ensure stable operation of the product.
Highly corrosive environments require targeted solutions to media erosion and material aging issues. The material selection is corrosion-resistant metal, the outer shell is sprayed with polytetrafluoroethylene or fluorocarbon coating, and the rubber seal is made of fluorine rubber; the structure adopts a fully sealed design, and the joints are filled with corrosion-resistant sealant to avoid media penetration. Electronic components are treated with anti-corrosion coatings, and circuit boards are painted with conformal anti-corrosion paint; mechanical components are coated with electroless nickel plating and matched with corrosion-resistant lubricants. It has passed salt spray test (neutral salt spray for 1000 hours) and chemical medium immersion test to ensure long-term stable operation in acid-base, salt spray and other environments.
