For cold storage to be more energy efficient, this should be done!

For cold storage to be more energy efficient, this should be done! 1. The index for reducing the unit heat flow of the cold storage enclosure structure. In the design of the cold storage, the unit heat flow q of the outer wall of the low-temperature cold storage is generally about 11.63W. If the q can be reduced to 6.9W, for a 5000T~10000T class In low-temperature cold storage, it is estimated that the power cost can be reduced by about 10%.

Matters needing attention

1.Oil and water protection of servo motor 1) The servo motor can be used in the place that will be attacked by water or oil drops, but it is not completely waterproof or oil-proof. Therefore, the servo motor should not be placed or used in the environment of water or oil invasion. 2) If the servo motor is connected to a reduction gear, the oil seal should be filled when using the servo motor to prevent the oil of the reduction gear from entering the servo motor 3) The cable of servo motor should not be immersed in oil or water.
