Revolving doors are commonly used in hotels, office buildings and other buildings, mainly including cap head, curved wall, revolving door body and electrical control device.The part of the cap head and the curved wall is a fixed part, that is, the part that does not rotate with the rotating door body.The other part of the cap head and the rotating door body is the rotating part.Because the main electrical control device of the revolving door is generally partly installed in the fixed part, the other part is installed in the rotating part, so it is necessary to use the sliding ring of the revolving door to solve the problem of signal and power connection between the fixed part and the rotating part.The conductive slip ring is usually installed in the cap head.The existing slip ring is a column slip ring, which comprises an insulating shaft, a conductive ring and a brush.The outer surface of the insulation shaft is a cylindrical surface, and a plurality of conductive rings are installed on the outer surface of the insulation shaft. They are coaxial with the insulation shaft and are distributed along the axial direction of the insulation shaft.The outer surface of the conducting ring is a cylindrical surface, which is in contact with the brush.




The rotation of the sliding ring of the revolving door


 

The number of conductive rings and brushes increases when there are more paths to carry the electrical signal.Because the conductive rings are distributed along the axial direction of the insulating shaft, the length of the insulating shaft will correspondingly increase as the number of conductive rings increases, and the overall axial length of the slip ring will increase.As the length of the slip ring becomes longer, the cover to install the slip ring also increases correspondingly, the space occupied by the cover becomes larger, and the cost of the revolving door becomes higher.In particular, the back spring of the two-wing revolving door is almost unusable.In addition, there is a line contact between the conductive ring and the brush of the back slip ring. On the other hand, the contact resistance is high, which is easy to generate sparks and is not conducive to the transmission of signals. On the other hand, the friction between the conductive ring and the brush causes a lot of noise.

 

CENO ECN series is one of the most cost-effective and most popular series of industrial slip rings. In many cases, it is also called hollow shaft slip ring, through hole slip ring, through hole slip ring, hollow shaft slip ring.Mainly used in 360 degree continuous rotation and need to ensure the power supply, signal can not interrupt the occasion:Such as all kinds of radar, security equipment, amusement equipment, all kinds of robot, manipulator, various aerostat, all kinds of wind power equipment bottle blowing machine, inspection machine, all kinds of turntable, recreational recreational equipment, virtual 3D and VR devices, vehicle-mounted satellite antenna, the ship borne satellite wires, cable reel, wipe a window machine equipment, rotary table, revolving stage, rotary screen, revolving restaurant,Electric construction machinery, the latest VR simulation equipment, etc.
