Why Aren't Mercury Slip Rings Widely Used?

图片
  Overview Slip rings are used to transmit power, signals, and data between the rotating and stationary parts of the rotating equipment. Mercury slip rings   serve the same purpose, yet they haven't been widely adopted. Today, let's discuss the reasons behind this.   What Are Mercury Slip Rings and How Do They Work? A mercury slip ring is a special type of slip ring, also known as a mercury - wetted slip ring or mercury contact. It uses liquid mercury as the conductive medium instead of traditional conductive components like carbon brushes to transfer signals and current between rotating devices. Due to its fluidity, when the rotor rotates, mercury maintains contact with the conductive ring at the molecular level throughout the rotation, ensuring a good electrical connection. Limitations of Mercury Slip Rings l Limited Operating Temperature :   Due to the large coefficient of thermal expansion of mercury, mercury slip rings cannot be used at high temperatures. Their ...

How to Wire the Conductive Slip Ring Correctly?

  Overview Conductive slip rings can transmit power, signals and data, and they can be used in rotating equipment such as industrial manufacturing and entertainment facilities. However, only when they are correctly wired can they operate normally. Today, ByTune will explain the correct operation skills to help you better use the slip rings.   The Wiring Part of the Slip Ring The conductive slip ring mainly consists of two parts: the stator (conductive ring) and the rotor (brush). Among them, the conductive ring is fixed on the copper ring of the upper bearing base, and its wiring port is connected to an external fixed power supply or signal source. The brush is fixed on the outer casing of the slip ring, and the outgoing line is generally designed near the central axis. The two achieve electrical conduction through close and continuous contact. Principles to be Noted When Wiring l Matching of Electrical Parameters: The rated voltage, current, number of channels and other param...

What Should We Know When We Install the Slip Rings?

1. Overview Conductive slip ring s are components that transmit electrical energy, video, control and other signals in rotating equipment. Improper installation of them may lead to signal interruption, poor contact and even equipment failure. So, do you know what needs to be noted when installing them?   2. Main Installation Methods Conventional conductive slip rings can be divided into two installation methods: through-hole installation and flange installation. Among them: (1) Flange Installation The flange installation of a conductive slip ring means that the slip ring is connected and installed with the equipment through its own flange structure. The flange is a disc-shaped edge part with mounting holes on it. These holes are designed to be fixed to the corresponding mounting positions on the equipment. Structurally, this flange is usually integrated with or tightly connected to the housing of the slip ring. ByTune supports designing corresponding flange plates according to the ...

How to Determine the Size When Customizing the Through-Hole Slip Rings?

  Overview Among various slip rings, the through-hole slip ring   has found extensive application due to its hollow structure. Cause this enables it to be expeditiously mounted onto the rotating shafts of equipment. And when customizing through-hole slip rings for devices like radar antennas, anti-drone systems, people select them with different sizes, materials with other parameters. So, do you know what are related to the through-hole slip ring size, and how we determine its appropriate size?   The Size of Through Bore Slip Ring Refers to: When we talk about its size, we are actually referring to the following parameters: 1. Inner Diameter:   The inner diameter of the through-hole slip ring is the diameter of the central hole in its structure. It also represents the size of the shaft that can pass through the slip ring. Typical inner diameter values are 12.7mm, 25.4mm, 38.1mm, 50.8mm and so on. 2. Outer Diameter : The outer diameter of the slip ring refers to the m...

What are the Applications of Pneumatic Slip Rings?

  Introduction Pneumatic slip ring s, also known as pneumatic-electric rotary joints or pneumatic-liquid slip rings. We use them to transfer pressurized or vacuum gases from the static inlet of a rotating device to the rotating outlet. Unlike common electrical slip rings, they are more suitable for transmitting fluid media, including steam, hydraulic oil and vacuum gases. Moreover, it can maintain a stable and separated liquid connection while rotating 360 degrees. But how exactly is this achieved? Working Principle of Pneumatic Slip Rings The main components include the stator, rotor, seals, bearings and transmission wires. Among them, the stator is usually stationary and connected to the external gas and liquid supply sources. The rotor rotates together with the rotating parts and transfers gas or liquid from the stator to the rotor through the internal channels and then distributes them to the corresponding working parts. Features of Pneumatic Slip Rings Continuous Rotation: ...

What are the Key Points in Through Hole Slip Rings Selection?

  Introduction In many devices involving rotational motion, through-hole slip rings   transmit electrical signals or power between their electrical components. However, how should we find the right slip ring? This article will give you a detailed introduction to the key points when selecting through-hole slip rings to help you make a decision.     1.  Size The through-hole size of a through-hole slip ring should be selected according to the diameter of the rotating shaft of the equipment. Generally, the through-hole diameter should be slightly larger than the diameter of the shaft to allow the shaft of the equipment to pass through the slip ring smoothly. For example, if the diameter of the rotating shaft of the equipment is 20 mm, then a slip ring with a through-hole diameter of 22 - 25 mm can be selected. We generally recommend reserving an installation gap of 0.5 - 3 mm. ByTune provides slip rings with an inner diameter of 3 to 500 mm, and the outer diameter ...

Wha are the Benefits of Gold-Contact Slip Rings?

In modern industry and technology, slip rings are used to transmit power and signals between different parts of equipment. When in use, it transmits current through 360-degree rotation, which has high requirements for the contact surface and transmission material. Among many choices, gold-contact slip rings stand out due to the use of precious metal contact materials. So, what are the benefits of such contact? Gold-to-gold Contact High Transmission Efficiency Gold, as an excellent conductor, has high conductivity and extremely low resistance. Its contact is more reliable than the contact of ordinary metal brush wires and copper rings, and can stably receive and transmit various currents, including weak current signals. This is very important for some precision instruments, such as ROV, UAV or semiconductor manufacturing equipment. Because even a tiny energy loss may affect their data accuracy. More Wear-resistant Structure During the working process of the slip ring, the rotor and st...
