Latest company news about The Advantages of Mercury Slip Rings

The conductive rotary joint ,with mercury as its fluid medium, called mercury conductive slip ring, also called mercury slip ring for short.It is a kind of industrial component.Compared with the traditional carbon brush slip ring, the biggest difference of mercury slip ring is that it adopts liquid mercury as its conductive medium and integrates the stationary part and rotary part,also it uses mercury for conductive transmission instead of carbon brush. Due to the simple structure of physical mechanical of rotary part, the product has the advantage of more reliability, free of maintenance, no noise, high speed, low price,no signal distortion, small contact resistance, larger current transmission.

Mercury slip ring mainly has the following advantages:

1.long life and wear resistance.The working life of mercury slip ring could be 10 to 50 times longer than electrical slip ring, the service life of hybrid mercury slip ring is about 3 to 5 times higher than the life of the electrical slip ring;

2.High temperature resistant.Mercury slip ring can work in more than 60 degrees temperature;

3.Very low electrical noise

4.Very low contact resistance (Less than 1mΩ)

5.Wear resistance, the mercury is inert material, it is more resistant to corrosion and wear

6.Suitable for signal and power transfer of rotating devices or instruments
7.Less lubrication

Because of these characteristics,mercury slip ring makes its products very attractive and competitive.
