First, the working principle of mercury slip ring

    What is a mercury slip ring? Simply put, it is a conductive rotary joint with mercury as the fluid medium, which is an industrial component. The working principle of the mercury slip ring is to use mercury to conduct electricity, mercury instead of brushes, with the advantages of no wear. Mercury slip ring, also known as mercury conductive ring or mercury conductive slip ring, mercury rotary joint.

Second, the advantages of mercury conductive slip rings and traditional slip rings

   The biggest difference between mercury conductive slip ring and traditional carbon brush slip ring is that it mainly uses liquid mercury as the conductive medium, integrates the fixed end and the rotating end together, and does not need to use carbon brush to conduct conductive transfer when rotating, but directly uses mercury to conduct conductive transfer. The slip ring is mainly the direct use of mercury to conduct conductive transmission, and the slip ring mainly refers to the link between the two parts, between the active part and the fixed part, the brush is used as a precision part of the signal transmission connection, which realizes the transmission of current, power and temperature signals between the two relative rotating parts. The mercury slip ring mainly refers to the slip ring whose transmission medium is mainly mercury. It is very different from the traditional collector ring, with the advantages of reliable use, high precision, support for high loop and high current.

Third, the characteristics of mercury conductive slip ring
 

    Compared with other slip rings, mercury slip rings have the characteristics of compact structure and small size due to the use of fluid as the medium. It is this feature that makes the mercury slip ring an indispensable role in the field of tiny precision instruments. Due to the fluid characteristics of mercury, the mercury slip ring rotates without wear, and the life is many times longer than the general slip ring, which is very suitable for conductive rotary joints that need to be rotated frequently. Because the rotating part of the mercury slip ring has no complex physical and mechanical structure, it has a reliable product
It has the advantages of high performance, and has the characteristics of maintenance-free, no noise, no noise, high speed, no signal distortion, small contact resistance, and large transfer current. It is with these advantages and characteristics above that mercury slip ring products have a very high market appeal and competitiveness. Although the price is relatively expensive, it has a place in many sophisticated fields.
