AsliThree comprehensive test bench temperature and humidity vibrationThere is a guide rail below the studio that allows the vibration table body to be removed and moved in (when the vibration table body is not being tested). The connection between the vibration table surface and the lower part of the studio is sealed using a multi-layer epoxy resin and high-temperature resistant silicone rubber alternating plug connection (for sealing). The heating system uses a finned stainless steel heater with a far-infrared nickel complex gold wire heating core. The two systems are independently controlled and do not interfere with each other. Supply air circulation system Xiangming motor (low noise), multi wing centrifugal wind turbine, single cycle.

2. The refrigeration system adopts a unit or binary low-temperature circuit system design.

3. American "Aigao" dry filter, Taiwan, China "Guanya" oil separator, Italian "Castrol" solenoid valve

4. Adopting a multi wing air supply fan for strong air circulation, avoiding any dead corners, can make the temperature and humidity distribution in the testing area uniform.

5. The design of air circulation for air outlet and return meets the testing standards for wind pressure and speed, and can quickly stabilize the temperature and humidity at the moment of opening the door.

6. Heating, cooling, and humidification systems can be independently improved Efficiency, reducing testing costs, increasing lifespan, and decreasing failure rates.

Three comprehensive test benchStructural features:

1. Main body: The main body shell is made of A3 steel plate and has undergone spray coating treatment, and the inner liner is made of SUS stainless steel mirror panel with insulation medium of ultra-fine glass wool.

2. Circulation method: Top centrifugal fan blades supply air, bottom return air.

3. A double-layer high-temperature resistant high tensile sealing strip is used between the door and the box to ensure the sealing of the testing area.

4. Adopting non reactive door handles makes operation easier.

5. The observation window is made of multi-layer insulated tempered glass, with a laminated conductive film on the inside (allowing for clear observation of the test process)

6. The lead hole (on the left side of the machine) can be used for external testing of power or signal lines (diameter 50mm).
