Wet Heat Testing of Marine Equipment

The ship equipment hot and humid test provides a method to simulate the hot and humid environment effects that the test sample may encounter on the ship in the laboratory, revealing the changes in the mechanical and electrical properties of the test product under the specified hot and humid environment conditions, and evaluating the adaptability of the test product under the hot and humid environment conditions of the ship based on the test outline and technical conditions of the test product.
Zhongke Testing Environmental Reliability Experiment Center has a variety of ship equipment environmental test equipment and has wet and heat test capabilities. It provides professional ship equipment wet and heat test services for ship gyrocompasses, ship radar ships, ship navigation equipment, ship communications and other equipment.

Humidity and heat are one of the important environmental factors for ship equipment. Ship equipment installed on open decks and engine rooms will be affected by high temperature and high humidity environments. Moisture and heat can deteriorate the physical and chemical properties of materials used in equipment, affecting equipment performance or even failure.
Some typical problems caused by ship equipment in hot and humid environments are as follows:
1. Moisture causes corrosion or lubricant deterioration, causing moving parts to get stuck;
2. After absorbing moisture, the material can expand, causing functional damage;
3. After absorbing moisture, the conductivity of the insulating material increases, resulting in reduced electrical and thermal properties, and reduced performance of electrical components;
4. Temperature and humidity cycles can cause condensation inside the sample, causing electrical short circuit;
5. The physical strength is reduced and the elasticity is reduced after getting damp.

Constant humidity and heat test: ship gyro compass, ship radar ship, ship navigation equipment, ship communication and other equipment, ship electric heating equipment. Alternating humidity and heat test: ship equipment, ship motor, transformer, ship electrical appliances, automation equipment, instruments, lamps, electronic appliances, electronic instruments, computers, electrical measuring instruments
