What is the difference between the maintenance of electric telescopic door in summer and winter

First of all, we should pay attention to the selection of materials. For the electric telescopic door suitable for cold weather, we should appropriately increase the hardness just now, and the change of expansion coefficient is not easy to be too large. This is the first consideration before choosing the manufacture of electric telescopic door. For the electric telescopic door used in the north, sometimes it will be about 30 degrees below zero in cold season and about 30 degrees above zero in summer, with a temperature difference of 60 degrees. If the material selection is not good, it will bring serious problems to the use of electric telescopic door, which is a problem worthy of attention for designers.

Secondly, we should replace the motor in time according to the change of season. Different motors are used in different seasons, which is the first principle to be followed by the equipment. We cannot artificially increase the use obstacles and maintenance obstacles. There is no antifreeze for motors in summer. Antifreeze must be added to motors in winter. This is the basic common sense of motor use. According to different places, there may be more stringent requirements for motors and special requirements for materials. These should be taken in o account in the design of electric telescopic doors and processed and produced according to local conditions and in a practical manner.
