More and more conductive sliding rings are applied to equipment, so the quality requirements of conductive sliding rings are stricter, which depends on the technology of the manufacturer you choose. Below, Baixuan Power summarizes the common problems of conductive sliding rings in the application process.
Common problems of conductive sliding ring in use:
Signal Conductive Sliding Ring Interferes Too Much
Conductive sliding ring can be used to transmit power and signal, and there will be interference between power and signal, which can be divided into internal interference and external interference. For the designer, the type of signal must be known clearly. For the special signal, special wires must be used for internal and external shielding. For the formed conductive slip ring, it is found that the signal of the conductive slip ring is disturbed, and the external conductor can be shielded by itself. If it is still unable to solve, the internal structure of the conductive slip ring can only be redesigned.
2. The protection level is not in conformity with the use environment.
Usually not specifically specified conductive slip ring, the protection level is IP54. If some customers do not add additional protection, they will be placed on the occasion with waterproof requirements, which will cause the internal water intake of the conductive sliding ring, resulting in internal short circuit and the failure of the conductive sliding ring.
3. Circuit design leads to unprotected circuit
Usually when the conductive slip rings leave the factory, the insulation performance of the products will be tested by high voltage above 5 times the working voltage. Even so, under some conditions, the conductive slip rings can not meet the demand, resulting in the breakdown and short-circuit burning down of the conductive slip rings.
4. Short Circuit of Conductive Sliding Ring
When the conductive sliding ring is used for a period of time, the short circuit phenomenon may be that the service life of the conductive sliding ring has reached, or that the overload of the conductive sliding ring causes the burning of the conductive sliding ring. Generally, if a short circuit appears in a new conductive sliding ring, it is caused by the problem of insulation material inside the conductive sliding ring, or the direct short circuit between brush wire and brush wire, and the breakage of conductor skin. This must be detected by exclusion method.
5. Overload Burning of Conductive Sliding Ring
The maximum allowable current of the conductive slip ring is determined by the cross-sectional area of the conductive ring, the contact area of the brush, the pressure between the brush and the contact surface, and the rotational speed. Beyond this value, the conductive slip ring may heat slightly, lightly, lightly, lightly on the contact surface, and even form a welding point between the brush and the conductive ring. Although a certain safety factor will be considered in the design stage of the conductive sliding ring, it is recommended that customers provide the manufacturer of the conductive sliding ring with the maximum current actually used.
6. Unsmooth rotation of conductive sliding ring
Eliminating the problem of assembling conductive slip rings and selecting bearings, the reason for this kind of problem is that customers usually choose conductive slip rings without putting forward aseismic requirements, and the environment used has strong vibration. It causes damage to thin-walled bearings in conductive sliding rings and rupture of plastic spindles.
