Slip ring brush and brush holder there is a gap between

The role of the generator slip ring carbon brushes generally used in the DC motor is used and implemented in conjunction commutation commutation, the DC becomes "AC", the drive DC motor rotation. Brushless DC motor is now more widely, it uses thyristor commutation circuit instead of brushes to achieve, you can achieve high-speed, large-capacity, low noise. Some also use the AC motor carbon brushes and conductive ring, for example, has its rotor windings, how to provide for rotation of the rotor current? Carbon brush with conductive ring can be achieved. The role of the commutator and the switching current on the current direction of the motor is the role of the brush (except the outer squirrel-cage motor) conduction current slidable contact body. Separate Slip Ring in DC, it also bears on the armature winding alternating electromotive force induced in for commutation (rectifier) ​​task. Unlike other high-current slip ring products, so choose your own slip ring products are important: the appropriate range, the proper accuracy, appropriate installation method, suitable output, etc., can affect the product's performance. As the brush and slip ring there is a gap between the brush holder and brush holder as a fixing member (such as the stems, etc.) under the stress of slight deformation of the brush section are slightly larger than the radius of curvature of the commutator or collector ring radius of curvature, which in the motor is running, the commutator or collector ring of the contact cross-sectional area of ​​the brush is not all, but only part of the area. Therefore, we must be cambered brush slip ring grinding, and make the commutator or collector ring basic agreement. Practical operation, the brush arc facing the commutator or collector ring contact area of ​​not less than 75% of a single brush section.

Slip ring insulating properties

Insulation of electrical slip ring is a very important performance properties, it is a measure of the reliability of slip ring is an important indicator, refers to the metal ring and metal rings, metal ring and the spindle between the metal ring and wire between the metal ring and the shell, between the wire and the wire insulation strength. Mainly due to the insulating properties of insulation material, the internal structure design. A good slip ring design on the one hand should give full play to the advantage of material, on the other hand should be avoided material on some of the flaws.

Metal ring and the insulating material between the metal ring, high-performance engineering plastics generally select or use an insulating film with a high-performance epoxy resin based insulating adhesive. Insulation sheet will generally use is to use some larger slip ring, like through-hole slip ring and some larger Customized Slip Rings, etc., using potting process is generally smaller cap slip ring and customized smaller slip ring. The dielectric strength of insulation adhesive gel formulation is mainly affected by the impact of technology and potting, insulating rubber generally uses about 60 percent of the epoxy resin, about 20 percent kaolin, about seven percent of phthalic acid dibutyl about five percent triethanolamine, and a few percent of other ingredients. Craft glue should avoid cracks in the curing process and bubbles, when the air humidity increases, the dielectric strength may be reduced. Between the metal ring and the metal ring to control the distance of at least 1.5mm.. After our trial and a unique selection of recipes potting process enables us to reach 1,000 megohms insulation resistance above, and then pressure test through a 50 Hz 1000 V test does not breakdown, and also through the high and low temperature case insulation test.

Mercury slip ring applications and deficiencies

As the name implies , mercury slip rings, is the use of mercury as a conductive medium, the slip ring assembly . Mercury is the only state at room temperature, liquid metal , precisely because of this feature, as well as metallic conductivity. Just let this idea become a reality. Is to mercury sealed within the slip ring , the fixed end and the rotating end integrated, rotating it directly through the conductive transfer of mercury to the current , the transmitted high accuracy, good stability, no noise in the transmission signal .

  Compared to other slip ring , since the medium is a fluid , creating a compact structure , small size features, this feature, tiny precision instruments in the field of special primary role of non- mercury slip ring perfectly. Because of the characteristics of mercury , when rotating slip ring wear , longer life expectancy than the average many times , in the need for frequent rotation conductive rotary joint , which is very appropriate. Since rotating parts without complicated mechanical structure makes the product more reliable and maintenance-free, no noise , no noise , high speed , low price signal is not distorted, contact resistance, pass more current .
Mercury slip ring wide range of applications ! From traditional industries to new industries , from the civilian sector to the military industries have to use mercury slip ring . Mercury as a material we all know , is a good conductor , compared with other materials such as copper , its conductivity is not bad, because mercury is liquid mercury as the medium of an electrical rotary joint , the main principle is the use of liquid mercury at room temperature while maintaining , and mercury can be conductive, and the resistance is small , the shape can be freely changed, so , and copper and other materials than on some occasions , more applicable , it can be said slip ring can be applied traditional occasions , mercury slip ring can be competent, but because mercury is highly toxic , and more expensive, so the market price to be higher than the slip ring a large portion of the mercury slip rings are generally used in relatively high-end devices ( such as a hospital CT) is more appropriate . Superconducting experimental use of mercury in there to achieve the conductivity of weak signal transmission, numbers and control current is very appropriate, more suitable for conventional slip ring incapable of areas, such as high- speed, low impedance, low interference and other occasions. Which applications are: automated packaging packaging machinery, packaging machinery hand , robots and other automated packaging .
Mercury slip ring advantages:Therefore, in its interior is not as complex as the mechanical slip ring structure . Volume ratio on the mechanical slip ring is much smaller , and this is one of its major strengths . When the rotation is mainly mercury internal molecular friction , and the friction between the seals , so that the mercury slip ring wear is very small , so its very long life , high speed , and without maintenance.

Mercury slip ring its shortcomings :
Since the thermal expansion coefficient of mercury , the mercury slip ring is not used at high temperatures , generally working temperature should not exceed 60 ° C , followed by its high precision mechanical sealing structure , one to let expensive, on the other hand to the working environment requirements efficiency, vibration environment must be shockproof , otherwise it will seriously affect the life.

Buying the importance of slip ring parameters

Select a product , we must first understand the basic characteristics of the product , parameters and function results. Also a variety of products , maybe there are many types , many specifications, we want according to their size of the device , operating environment and other factors to select the appropriate parts. Especially the slip ring types of products , it is very important , the type and size is very important, otherwise it may cause can not be installed even lead to major consequences of industrial accidents , therefore , slip ring before installing , choose a suitable slip ring is the primary task .

       Collector rings main parameters of the number of paths , job rotation , temperature , Humidity, contact material, wire length , shell material , torque, and protection levels, etc. , in addition to these Operating humidity also affect the insulation resistance of a slip ring very important mechanical factor in high humidity environments, separated by too close to the high voltage path it is easy to breakdown, causing a short circuit or a more serious accident , so the humidity is not too high , at the time of purchase , must be to investigate the device working environment humidity range , to avoid unnecessary production safety accidents .
       In general, the slip ring normal operating temperature of -40 to 80 degrees.
       Contact material on the performance of the entire slip ring plays a very crucial role , contact materials need to have several important features, such as wear resistance, high temperature resistance , small resistance , etc., when the need for slip rings work 24-hour operation If the wear is not good , it is likely to cause aging, damage and other problems , leading to poor contact , signal transmission is not smooth . Temperature is the same reason , friction and heat, rotating at high speed when the heat generated by friction can cause contact material contact point temperature is particularly high, if not high temperature, contact material melts easily . Conductivity can not say more , contact the contact area is not too large , and therefore requires a very good electrical properties.

      Jing Pei electronic contacts using imported materials to ensure the quality of electrical slip ring ! Slip ring low contact resistance , long life, high precision, transmission speed, low electrical noise !

      Jing Pei electronic test process improvement , slip rings for the main product performance testing are: Overall assembly dimensions for the test of single contact resistance in the test operation of the slip ring contact resistance testing, the loop between the dielectric strength, compressive strength testing, rotation friction torque is detected.

      Therefore , the crystal Pei Electronics has been in the domestic electrical slip ring production industry pioneer !

Separate slip ring for the future development prospects

Speaking separate slip rings trends, familiar with the industry people know that in previous years the explosive speed cameras increases, to each slip ring manufacturer has brought great opportunities for development , it also brings a real in orders and profits.

       Productivity in science and technology to change the way today , industrial production has undergone tremendous changes. Through these years to carry out , slip ring skills are now very mature, simple once modeled from high-quality foreign ring to the current independent innovation depict special non-standard slip ring , has been a qualitative jump , has been on a very high level. This coupled two years, as countries are changing the economic growth mode, adjust the economic structure, economic development from the large investment , the real estate industry and gradually developed into new industries and consumer services. Machine instead of doing complete the production process is a modern industrial control costs, improve efficiency and enhance the quality of the principal means.
       But man can complete machine can accomplish a number of complex processes , instead of doing so manually to achieve the machine , you need to keep the process can be simplified in order to fit in the machine production . But also to improve the processing capabilities of machinery and equipment , there are many devices can be used on a rotating platform , rotary joints and other accessories, in the above by installing the slip ring to connect the device to achieve increased functionality , improve performance , and expand the scope and difficulty of processing . Separate Slip Rings in a variety of production, processing, packaging equipment application it is numerous, such as: production robots, material handling systems , machining centers, rotary processing platform , packaging machinery and so on .
       In this case , the conductive slip ring can be the perfect solution to this problem . In such a big opportunity in the context of each slip ring manufacturer in addition to the conditions of preparation to do their hardware outside , should strengthen the cultivation of soft power , slip ring introduction and training of professionals is urgent , experienced designers and engineer is to determine the weight of the main future competition .

       So, we should give top priority to the introduction and cultivation of talents , crystal Pei Electronics spends more than 10% of sales revenue for research and development of re- investment in research to retain the slip ring type people but also to ensure the slip ring quality ! Because of this, Jing Pei electronics industry of the slip ring to the growing strength !
