Common problems in the use of conductive slip rings

The following are some common problems in the use of conductive slip ring summarized by HAUREM Company, so that more customers can understand the slip ring and better use the slip ring.

1. Rotation of conductive slip ring: because the standard slip ring does not have the load-bearing function, when the user uses the slip ring, the excessive weight bearing or impact will cause the damage of the slip ring. When the application environment needs the slip ring bearing or bearing a large impact, it is necessary to communicate with us to choose the load-bearing slip ring or anti-impact slip ring.

2. Slip ring adjacent two direct short circuit: due to accidental impact or excessive vibration, resulting in filamentary brush runway, making the short circuit between adjacent. Use seismic packaging as far as possible, and the vibration environment adopts seismic design.

3. The protection level is to reach: in the environment with water or high humidity or large dust, use the conductive slip ring without waterproof and dust-proof design, making the internal water of the slip ring, causing internal short circuit, or a large amount of dust into the slip ring causing the slip ring failure.

4. Overload and burning of the sliding ring: the maximum current allowed by the sliding ring is the current value that can operate safely according to the cross-sectional area of the conductive ring, the brush contact area, the pressure of the brush and the contact surface, and the speed and other comprehensive factors. Beyond this value, the conductive slip ring may have a light heat, the heavy contact surface fire, and even form a welding point between the brush and the conductive ring. Although some safety factor will be considered in the design stage of the conductive slip ring, it is still recommended that the customer provide the sliding ring manufacturer according to the maximum current actually used.
