Basic characteristics of mercury slip ring
First, people talk about the basic structure and principle of mercury slip ring. Then people summarize and analyze the advantages and disadvantages of mercury slip ring in detail. It is also called mercury conductive ring or mercury conductive slip ring. Simply speaking, this kind of conductive compensator with mercury as hydrodynamics material is produced in this industry. The big difference between the parts and the traditional motor brush slip ring depends on the fact that the liquid mercury is the conductive medium, which integrates the fixed end and the rotating end. When rotating, the motor brush is not used to carry out the conductivity transmission, but Mercury is used to carry out the conductivity transmission immediately. Because some of the rotating parts have no complicated physical and mechanical structure, which makes the products more reliable, maintenance free, noise free, low noise, high speed ratio, low price, no loss of frame data signal, small contact resistance, and greater current transmission.
The key advantages of mercury slip ring are long life and wear resistance -- the fatigue service life of mercury slip ring is expected to be 12-60 times longer than that of electric slip ring, and the service life of mixed mercury slip ring is also 3-5 times longer than that of electric slip ring; heat resistance -- Mercury slip ring can work at a temperature of about 65 degrees; high rigidity -- due to the high elastic mold of mercury raw material, its rigidity is 15-20% larger than that of ordinary steel slip ring; torsion Low distance - according to the structure, the torque of mercury slip ring is reduced by about 1 / 3; the rotating speed ratio and acceleration capacity are high - it can operate under the DN value of more than 4 million, and the deviation, damage and scalding can be reduced; wear resistance - because the mercury raw material is plastic raw material, it is more resistant to corrosion and damage; very little needs to be moistened - the friction index of mercury raw material is low, and the oil moistened mercury is selected Slip ring, under the condition of thin grease or poor oil, its lubrication capacity is still higher than that of the traditional lubricant commonly used for steel slip ring; moreover, it has the above characteristics. The advantages of mercury slip ring make its products very attractive and competitive.
The key of slip ring refers to the interface between two parts. Among the active parts and fixed parts, carbon brush is selected as the high-precision part for data signal transmission and connection. It keeps the current, output power and temperature data signal transmission between two relative rotating parts. The key of mercury slip ring refers to the key of broadband access technology, mercury. Leading slip ring. It is quite different from the traditional collector ring in that it has the advantages of reliable application, high precision, high loop and high electric flow.
With the advantages and disadvantages of left and right, the sales market and main use of mercury slip ring are quite common. In many places that people don't often encounter, especially in very unique places, people must use this kind of expensive mercury slip ring.
