Five factors affecting the service life of slip ring
1, The use of conductive slip ring material
As is known to all, when the conductive slip ring is running, the stator and rotor are transferred by friction.Therefore, the choice of wear-resistant material is very important. In general, the brush wire made of multiple alloy is used for precision conductive slip ring, which has good wear resistance and good electrical conductivity.Imported raw material is used for insulating materials to prevent secondary use of nozzle material, which is conducive to the guarantee of insulating performance.For the shell part, the material is better aluminum alloy material or high quality stainless steel material, good strength, strong manufacturability.
2,The use of conductive slip ring environment
Although said that the service life of the conductive slip ring with the manufacturer's production process and production material has much to do, but in a lot of time, the use of the slip ring correctly or not also determines the lifespan of the slip ring, in general, use and maintain the good of the service life of the slip ring in 5 to 10 years, on the contrary, if long time in the damp, high temperature, high pressure, corrosion environment using the slip ring is greatly shorten service life.Therefore, when we use the conductive slip ring, it is best to place it in a ventilated place, away from high temperature and high pressure, so as to avoid unnecessary waste and normal maintenance of the equipment operation.
3, The overall structure of the conductive slip ring
In order to facilitate customers to better use the slip ring in the process of installing the slip ring, conductive ring engineers design different structures of the slip ring according to the type of installation equipment: through hole conductive ring, cap conductive ring, disk conductive ring, separated conductive ring, etc.
Customers can make different choices according to the requirements of the conductive slip ring. Because of the different structure of the conductive slip ring, the service life of the conductive slip ring is also different. Among them, the service life of the conductive slip ring transformed by the hole will be longer.
4, The working speed of the conductive slip ring
The conductive slip ring itself has no speed, and its own torque is small. It relies on mechanical equipment to drive the slip ring to rotate.According to the working speed of the customer's mechanical equipment and the internal structure and performance characteristics of the conductive slip ring, the working speed of the slip ring with different structure types is different. When using the slip ring, the working speed of the mechanical equipment should not be greater than the set speed of the slip ring, otherwise the service life of the slip ring will be affected.For different sizes of slip rings, at work are ring and brush direct friction, at the same working speed, the corresponding linear speed is different, the greater the ring on the conductive slip ring wear is greater, relatively speaking, the service life is also greatly reduced.
5, Conductive slip ring assembly process
The first requirement of the custom slip ring is to ensure the integrity and correctness of the design product pattern, analyze the structure technology of the product, and clarify the assembly relationship between the slip ring and the installation equipment.Secondly, on the premise of ensuring the quality of the slip ring, strive to improve its quality, in order to achieve the service life of the slip ring.Finally, the parameter detection of the conductive slip ring can better reflect the comprehensive performance of the conductive slip ring to find and solve problems in time. The detection parameters include the product appearance structure detection, the normal life detection of the conductive slip ring, the static contact resistance, the dynamic contact resistance, the insulation resistance, the electrical strength and the friction torque detection.
