Optical slip ring selection

fiber optic rotary joint sliding electrical contacts are connected to application areas , it is also known as the collector ring , or rotary joints , rotary electrical interface , slip ring , slip ring , ring back , coils, commutator , adapters, is to achieve two relatively rotating body images , data, and power transmission precision signal transmission devices. Particularly suitable for unrestricted continuous rotation while rotating from a stationary position to the transmitting power or data of the place.

Consisting of elastic material - brushes sliding contact surface material - electrically conductive ring , insulation materials , bonding materials , composite stent , precision bearings , dust and other ancillary parts and other components. Brush adopt noble metal alloy material , was "II" -type conductive ring groove symmetrical double exposure , with the flexibility of the brush pressure and sliding contact conductive ring groove to transmit signals and currents.

Precision slip ring are high-tech products, has long been used in cutting-edge military field , a variety of precision turntable , centrifuges and inertial navigation equipment, key components . As China's economy continues to develop , more and more civilian areas involved in the use of such products for the industrial automation systems control . In advanced countries , these products have been gradually transformed by the military products for civilian products, standardization has been achieved in recent years , mass production , is widely used in security , factory automation, electricity, finance , instrumentation , aerospace , military, transportation , construction and other mechanical and electrical equipment.

Currently used internationally slip ring technology is divided into the following three:

1 , composite brush block technique commonly used carbon brushes, copper brush , silver / graphite / molybdenum disulfide brush block and other forms.

         2 , the use of precious metal alloy filaments , such as AuNi9 so on.

         3 , fiber brush technology , fiber brush is a special kind of sliding electrical contact design . Simply put, fiber brush is to separate the metal filament ( line ) for calibration and put into a metal tube. In this cantilever design, fiber brush bundles in bulk , without shackles attached to one end of the ring road surface trough .

In the industrial market, the rapid development, technical service and maintenance team is also essential, and we choose the collector rings, brushes when we should try to select the excellent quality team , so as to avoid unnecessary trouble. Shenzhen Crystal Electronics Co., Ltd. is a leading Pei , with years of experience focused on the development, production and sales of series of industrial brushes , slip ring, slip ring , conductive ring of high-tech companies . Jing Pei Electronics product line, and various indicators of performance is always at the forefront of similar products , with a number of international authoritative testing organizations that certificate, long-term domestic and foreign well-known manufacturers , military units , research institutes and universities to provide products and technical services, and become a long-term point of qualified suppliers , products are exported to Europe and America, most of the developed countries.

Large current slip ring in wind power systems is laden with the power of the whole system

High current slip ring for wind power generation system responsible for the entire system of power, control signals and data transmission capabilities, is the fan very crucial parts of the system , its precision , reliability and working life directly affects the performance of wind power generation system . Wind power generation systems for specific application requirements as well as China 's actual use of the environment , Jing Pei Electronics R & D team are specially designed and developed China 's wind power generation system dedicated slip ring . Key main material using imported materials , the internal built with advanced production equipment and a variety of slip rings for wind power performance testing system that allows crystal Pei wind slip ring with good resistance to low temperature, high humidity, wind resistance , corrosion resistance, impact resistance, anti-vibration , stable performance, no maintenance and other characteristics , the service life of up to 20 years or millions rpm.
Jing Pei Electronics is tailored to a variety of wind power equipment manufacturers specifications Wind Turbine Slip Rings, is widely used in the power generation power 600KW - 5MW wind power generation system . Options include cable length , connection, encoder type , pressure + data transmission , high-voltage current (300A) and so on .

         Slip ring brushes and slip ring split the normal operation of the motor there is a great relationship. Brush unit pressure should be " brush technical performance table " to choose. For high speed motor or work under conditions of vibration motor units should increase the pressure in order to ensure normal operation . In principle, the same motor should be used the same type of brush . Different types of brushes , such as the absence of special circumstances can not be used on the same motor , otherwise it is prone to failure. For individual commutation particularly difficult medium-sized motor, can double vessel brush , slide it into the side using lubricating properties, slide side using a strong ability to suppress sparks brush , so that the brush runs improved.


    Electronics Co., Ltd. Shenzhen Jing Pei produced slip ring can fully meet unrestricted 360-degree rotation of the power, control and digital signal hybrid transmission ; using advanced fiber optic rotary joint technology , maintenance-free , no oil ; each multi- point contact , low- contact pressure , low noise and low contact wear, long life ; standardized, modular design, product specification is complete, and can provide customized products needed .
