How to maintain the slip ring in use and prolong its life?

Slip rings, also known as rotary electrical interfaces, electrical rotary joints, can be used in any electrical system that requires unrestricted continuous rotation to transmit power and data signals from a fixed structure to a rotating structure. A device that transmits electrical signals and electrical energy between the rotating parts of the antenna frame and the stationary parts by means of sliding or rolling contact, electrostatic coupling, or electromagnetic coupling of conductive parts. On the rotating parts are the driving elements, measuring elements and control elements, to which control signals and power must be supplied from the machine room.

This requires a variety of slip ring assemblies to transmit signals and energy. Some radars need to rotate more than 100 lines. Slip ring assembly can be divided into following according to the frequency of the transmitted signal

Low-frequency slip rings, medium-frequency slip rings, and high-frequency rotating hinges. Slip rings usually refer to only the first two. The electrical performance index of the slip ring assembly is:

Insulation resistance....

Senrip slip rings are maintenance-free for life, as long as they are used normally according to the design parameters, they can achieve the maximum service life, and there is no need to worry about how to maintain.

The life of the slip ring is not by time, it depends on the speed, such as 10 rpm in 1 minute, 5000 rpm in 1 minute. Senrip slip rings are divided into ordinary speed slip rings and high-speed slip rings, and the longest life of Senrip slip rings can reach 20 years.

Conductive slip rings, also known as electric slip rings, combiner rings or collector rings, are components that provide sliding connections, and are connection devices for analog or digital signals and power transmission of two opposing rotating mechanisms. Jingpei slip rings have the advantages of safety, reliability, stability, high and low temperature resistance, maintenance-free and long service life.

Generally speaking, the life of a slip ring is certain. A well-maintained slip ring has a lifespan of 5 - 10 years, and a longer service life needs to be customized. If the slip ring is used in humid, high-temperature, high-pressure and corrosive environments for a long time, the service life of the slip ring will be greatly shortened.

So in practical application, how to maintain the service life of slip rings?

1. When using slip rings, please install the slip rings correctly according to the installation instructions of the slip ring manufacturer, and avoid exceeding the maximum voltage and current that the slip ring can withstand during use.

2. Understand the slip ring material and assembly process of conductive slip ring manufacturers. At present, the quality of slip rings is mainly determined by the difficulty of slip ring assembly and internal composition materials, especially the core materials inside the slip ring, and the quality of the material determines the quality and service life of the slip ring.

3. Provide the working speed of the conductive slip ring according to the actual needs. Environmental problems around the slip ring, the speed of the slip ring itself and the temperature rise of the bearing, the Joule effect of the electrical contact points of the slip ring, and the heating of the internal conductor can all affect the service life.

4. Pay attention to the environment in which the slip ring is used. When using conductive slip rings, it is best to place them in a ventilated place, away from high temperature and high pressure, and avoid using the slip ring for a long time at high temperature and low temperature. Generally, the operating temperature of the slip ring is -45 +85, beyond the range, it will lead to a rapid decline in the life of the slip ring, serious and even direct damage, except for the special slip ring, such as high temperature and low temperature resistance.

5. When purchasing slip rings, provide relevant parameters to the slip ring manufacturer according to the equipment requirements, so that the slip ring manufacturer can accurately provide products or provide you with design solutions. These data include the number of paths, the rated maximum current, voltage, wiring method, operating speed, temperature, transmission signal type, etc.

At present, some slip ring manufacturers only provide customers with a similar appearance of the product to the user, and ignore the important aspects such as the selection, design, manufacturing, installation and maintenance of the slip ring, and the user experience is not good. Some imported products have similar problems.

The life of the slip ring depends on the internal design structure and material of the slip ring, but it also depends on the use environment and correct use and maintenance of the slip ring. To ensure the correct use and maintenance of slip ringsJingpei1. When purchasing slip rings, it is necessary to provide relevant data to the slip ring manufacturers according to the equipment requirements, so that the manufacturers can accurately provide products or provide you with design solutions. These data include the number of paths, rated current and voltage, wiring method, operating speed, temperature, transmission signal type, etc.

2. When using slip rings, it is necessary to install the slip rings correctly according to the installation guidelines of the slip ring manufacturer, and avoid exceeding the maximum voltage and current that the slip ring can withstand during use!

3. It should be used in a dry, non-corrosive gas, no strong acid, strong alkali erosion, so as to avoid rust of metal parts and reduce the insulation performance of electrical components. Except for special slip rings, such as acid and alkali resistant slip rings, etc.

4. Avoid the slip ring to be used in a high temperature and low temperature environment for a long time, the usual slip ring use temperature is -40 +80, beyond this range, it will lead to a rapid decline in the life of the slip ring, serious and even direct damage. Except for special slip rings, such as high temperature and low temperature resistance.

5. It is best to adjust the contact between the slip ring brush filament and the ring groove to make the brush filament press well on the ring groove, and at the same time do not affect the rotation of the slip ring, if the pressure is not adjusted, it will cause virtual contact, the pressure is not enough, and the pressure is too large and the friction moment will be increased, so that the contact part is worn out greatly, and the service life of the slip ring is shortened.

6. Avoid the erosion of dust when storing the slip ring, if the environmental clarity does not reach a certain level, it will cause dirt on the surface of the ring groove, and it will also cause virtual contact or increase the resistance value. Except for special slip rings, such as the requirements of high protection level.

7. The slip ring cannot withstand the external gravity impact, otherwise it will deform the slip ring and affect its internal structure.

8. In the process of installing the slip ring, the reasonable radial clearance has a great influence on the life of the slip ring, if the radial clearance of the slip ring increases, the load area in the slip ring will be reduced, and the maximum rolling element load will increase, thereby reducing the life of the slip ring.

The material of the brush material and the contact surface, the thickness of the plating, the clamping angle between the brush and the contact surface, the friction force, the concentricity of the rotation of the slip ring, and the rest depend on the speed and frequency of use of the slip ring, and whether there is interference.

Consider a few aspects: (Mofrolon Slip Ring Experience).

1.The conductive slip ring itself does not have speed, its own torque is small, and 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 of different structural types is not the same, and when using the slip ring, the working speed of the mechanical equipment is required not to be greater than the set speed of the slip ring, otherwise the service life of the slip ring will be affected.

2.The wear resistance of slip rings directly affects the service life of slip rings. In general, excellent electrical conductivity is required, but also corrosion resistance, and when sliding contact with brushes, it must have wear resistance and stable sliding contact characteristics.

3.Although the service life of the conductive slip ring has a great relationship with the manufacturer's production process and production materials, but in many cases, the correct use of the slip ring also determines the life of the slip ring, generally speaking, the service life of the slip ring with good use and maintenance is 5-10 years, on the contrary, if the slip ring is used in the humid, high temperature, high pressure and corrosive environment for a long time, the life of the slip ring is greatly shortened. Therefore, when we use conductive slip rings, it is best to place them in a ventilated place, away from high temperature and high pressure, so as to avoid unnecessary waste and normal maintenance of the operation of the equipment.

4.It also includes the working current, voltage, number of channels and other reasons, which must be considered in the design. The correct use of slip rings is the magic weapon for extending the life of slip rings.

The life of slip rings is not easy to say, and the application fields of different types of slip rings are different, and the design life is also different. It can be used for more than ten or twenty years, and if your equipment runs at high speed for 24 hours, the life of the slip ring is naturally short. If your equipment needs to run at high speed for 24 hours, you can use Senrip high-speed slip rings.

Conductive slip rings are also known as brushes, busbar rings or collector rings, in practical applications, a very important problem is the working life of the slip ring, which affects the working life of the slip ring due to the following factors:

1.The structure of conductive slip rings varies by tens or hundreds of times in the life of different structures.

2.The material of the conductive slip ring.

3.Assembly process of slip rings.

4.The working speed of the conductive slip ring.

The conductive slip ring is mainly composed of several major components such as rotor mandrel assembly, stator brush line assembly, cap cover, bearing, etc., and its working principle is that the rotor mandrel assembly rotates each other through the bearing and the stator brush line assembly, and transmits signals and currents with the sliding contact of the conductive ring ring groove of the rotor mandrel assembly with the help of the elastic pressure of the stator brush line assembly. Slip rings transmit current or signals when rotating, and a bearing must be inside to rotate when they need to rotate. Therefore, the choice of conductive slip ring material bearing is very important.

Jingpei Electronics has strict quality testing standards and perfect after-sales service. The bearing is inside the slip ring, we need to disassemble the slip ring and replace it with a new bearing, and then send it back to you after testing. Jingpei slip ring, because of you turn, serve the world!
