Successful R&D and Test for Waterproof Slip Ring

Waterproof slip ring is one of the classification for general slip ring, which normally be used for moisture, corrosion and special underwater environment. The application is for ship, navigation equipment, underwater robot and so on to transfer precise signal, weak &big current, high voltage, low electrical noise, low torque and longer lie time. As we all know, the degree for waterproof could be divided into below ten parts:

1. No protection.
2. Drip-proof type one: The water drops vertically has no harmful effects
3. Drip-proof type two: The water drops vertically within 15 meter square range has no harmful effects.
4. Rain-proof type: Rainfall at vertical direction within 60 degree range has no harmful effects.
5. Splash-proof type: Water splash at any direction has no harmful effects.
6. Jet-proof type: Water injection at any direction has no harmful effects.
7. Water-proof type: Water will not directly jet into the internal at any direction.
8. Immersion-proof type: Even submerged in water which will not enter inside under the conditions stipulated.
9. Long immersion-proof type: Long immersion in a certain pressure environment can use all the same. 10. Moisture-proof type: Could be used in relative humidity below 90% moisture.

The Classification and Application of Slip Ring

Slip ring is the center conduction of connecting ring and the outer of lead wire as a shield ring. Transmission of more than 12MHz signal ususally uses coaxial lines of Shielded slip ring--Coax Rotary Joint, the cross section of this kind of slip ring like a trough shape, actually it is rectangular coaxial conductor. Also there is a kind of capactive intermediate frequency slip ring, which has a circular center conductor with using insulation to support shielding layer. Intermediate frequency slip ring is a kind of component that could be used to transmit radar intermediate-frequency ( tens of Megahertz ) signal and power. This type of slip ring enjoys high frequency, transferring below 12MHz frequency can use ordinary slip ring, say capsule slip ring with different diameter.


Low frequency slip ring takes advantage of contacting to transmit low frequency signal and power. For example, one of the type of cylindrical slip ring which of conduction ring can be divided into flat and V-shaped ring. Conductive ring materials normally use red copper, brass, silver and gold and the brush materials adopt palladium alloy, hexabasic alloy, gold to gold plated or copper graphite brush.

The electrical indicators of slip ring are: insulation resistance, contacting resistance, dielectric strength and electrical noise. For intermediate frequency slip ring which should consider shielding, impedance matching, noise, voltage and so on because of high frequency. Making sure reliable contacting and all lines contacted in a row on the structure designing process. Therefore, brush materials should have good conduction performance, good grinding, low friction torque with easy maintenance.


The structure types of cylindrical slip ring as per installation request can be divided into shaft and through hole slip ring. Which important technical specifications need to provided when choose slip ring? 1. Circuits 2. Current and Voltage 3. Work speed 4. Work temperature 5. Dimension 6. IP degree.


Does conductive slip ring has signal resistance measure?
Answer: Slip ring enjoys compact structure and design which can pass various digital and analog signal with using gold to gold contact materials. From the current technology on the structure design, slip ring could completely avoid interference problem between power and signal or signal between signal, also can prevent outside electromagnetic interference to the inside of slip ring.


How many signals that slip ring could transfer?
Answer: Now slip ring can transmit all low and medium frequency signal, CAN bus signal etc. For example, Inter Bus, Can Bus, Profibus, RS422, RS485, PLC cotrol, analog video, digital audio, gigabit Ethernet, sensor signal and so on.


Nowadays, slip ring are widely applied in the field of national defense military, such as reconnaissance aircraft equipment and air defense radar artillery system, early warning and antenna and the missile test system.


Barlin Times has many different types of slip ring which received great welcome from the customers at home and abroad.

The common failure cause and solutions for brush a

The normal failures of brush in the operation could be heating, spark, serious loss of electrical brush and collector. From the overheating fault causes, it basically has below aspects:

1. Poor ventilation condition: the main problem is for cooling air duct blockage, ventilation groove and vent plug blockage or the reduction of circulation fan air volume on the surface of collector. Especially, when the surface of slip ring has high temperature under operation, which will lead to brush wearing and powdered carbon accumulation increasingly, then may block heating channels of slip ring surface. Therefore, when supplier do repairing works, they should make cleaning for the ventilation groove or hole and cooling air duct ventilation groove on the surface of slip ring to maintain patency. For the turning slip ring for several times, if the ventilation groove height on the surface of slip ring is less than 5mm and has been turning to the radial limited hole which should be carried out the specification in according to the minimum use of outer diameter to change to make sure reliable heating performance of slip ring.

2. Bigger contact resistance or uneven distribution: slip ring and brush both are through mutual sliding contact to pass conduction current. With different capacity and models, there will be distributed around ten pcs brushs on the slip ring, and also with different contact resistance and current which can lead to uneven heating.

Slip ring brush, as we all know, which consist of slip ring and brush two parts. Actually, we called it conductive slip ring, collector or sliprings. Generally, slip ring applied to 360 degree rotation application that need to transmit current and signal. With the development of the industry, slip ring brush enjoys wider application which is currently used in high speed camera, electrical test equipment, rotating table, robotics, medical machine, wind turbine generator, packing machine etc.

The slip ring produced and researched & developed by Barlin Times has high reputation in this field and get high praise from our customers at home and abroad. http://www.barlintimes.com/product/carbon-brush-slip-ring.html
 

The Introduction of Mercury Slip Ring And Non-merc

Mercury slip ring also could be called mercury conductive rotary connector or mercury conductive slip ring. Shortly speaking, mercury rotary joint is a kind of industrial parts which use fluid medium to transmit signal or power. The biggest difference compared with traditional carbon brush slip ring is that it is mainly for liquid silver conductive medium, also the rotating part and fixed part combined together. Under the operation, it do not need to use carbon brush for conductive transmission, but directly use mercury to transfer power. At the another hand, there is a slip ring called non-mercury rotary joint, which uses a special gallium alloy liquid metal to pass power without mercury. This non-mercury type slip ring can meet the demand who require ROHS certification in some specific equipment. That is why, Barlin Times launched this new non-mercury slip ring into market soon after around one year hard working by technical engineers. Both of these rotary connector has the main feature of strong stability, high precious signal and very low noise. Meanwhile, compared with the traditional mechanical slip rings, both rotary connector are smaller size, easier installation and free maintenance, etc.
 

Features:

High work speed & big current

Less than 1mΩ contact resistance, no noise

Compact structure, easy installation and smooth operation

Free maintenance and more durable than traditional slip ring

Apply to any rotating device to transmit various signal and power

Non-mercury slip ring is optional ( Conform to CE, RoHs certification )

Stainless steel and aluminum alloy housing is optional

Contact pin and lead wire installation is optional


 

Application:

Rotating table, rotating camera and rotary lamp box

Cable wheel, winding machine

Resistors cutting machine

Robot arm

Wind turbine generator

Medical equipment, spinning LED sign board

Manufacturing and handling control machine


Notice for using non-mercury slip ring:

The minimum temperature for liquid metal 46L

Soild temperateure: +7.6℃


There is a “super cool” effect, when a slip ring contain liquid metal 46L, put in the room temperature 0℃, the liquid metal will not be solid immediately, there will have a 2-4 days range the liquid metal 46L will keep in liquid status, just like the river water still run in the 0℃.

The liquid metal slip rings are recommended to be used within 3 months after shipping. If the slip ring has rotation not smooth condition after 3 months storage in the room temperature +8℃, please put it in the warm room ( over 50℃) to recover the liquid metal status.

The liquid metal is not so sticky like mercury which can be sticky (touched) on the silver plated conductor surface. The liquid metal slip rings’ vibration resistance ability is much less than mercury types. Any light vibration, impact, shock will make the liquid metal to move out from the main conductor chamber to another conductor’s room. That will make short circuit easily.
