Technical Assistance Q collector ring

Slip rings, commutator , commutator motors are made use of for what ?

Collector ring applied within the AC synchronous motor and AC motor winding and commutator and also the commutator around the use with the DC motor .

Will the spark generator collector ring as well a lot what ?

Sparks may well be produced by a range of motives , for instance: ring and brush get in touch with corrosion took location ; brush pressure is also sizeable ; collecting ring surface is dirty ; brushes badly worn and so on.

brushless slip ring bad , what will come about then ?
May very well direct burning ring of fire or slip rings and brushes . Particularly: 1 , the contact resistance becomes substantial , the excitation existing is lowered two, in order that the carbon brush and slip ring overheating , and in serious fire three , sparking amongst brushes and slip rings , slip rings take place causing electrical erosion , escalating wear and tear and huge.

Generator collector ring what part ?

Briefly , the generator rotor winding collector ring terminals , the excitation existing is passed via the brush ring make contact with with all the conveyor 2 towards the rotor excitation .

Will you have the ability to LPR series of collector rings too massive current ? It can give installation directions ?

We LPR series slip rings are more than 15 amperes maximum power , if you ever have to have greater present over , we can advocate other comparable products, similar to hollow shaft -LPT series ( just like design and style structure no requirement ) . Needless to say, please get in touch with our sales engineers, they're going to offer installation instructions to you.

LPK series collector ring if do PCB design ? And is usually a separate , not the whole ?
Undoubtedly, we do slip ring disc separation and integration of structural design to meet client needs of diverse applications , including models LPKS-0205 is a typical instance - Disc separate slip ring ( split plus the PCB structure ) .

The collector ring you might have proof certification?

Our business has not however made ??explosion-proof certification.

Collector rings in completely different sizes and shapes , what disc collector ring and slip ring hollow shaft in the application of what is completely different ?

User correct size or space, for instance length ( thickness ) have specific needs, disc conductive ring could be the perfect remedy.
Selection of use in real life , collector rings combine dust and water can certainly do ?
Several sorts of collector ring will have an optional enclosure protection , that is what you stated ---- dustproof and waterproof . But, the user can not be immersed in the water collector rings , should be fitted with a protective coat .

Slip ring slip ring is still the main force of low-cost

As the name suggests is used to electrically conductive slip ring slip ring slip ring series in all the most widely used , also known as brushless slip ring , carbon brushes, slip ring, slip ring , slip ring , rotary pass, rotating electrical joints, dedicated to the unlimited continuous rotation , the transmission power of power, signal power .

The choice of the motor brush commutation sparks have an important role in inhibition , should be power, voltage , load characteristics and the selection conditions such as the peripheral speed commutator . Commonly used electric graphite brushes , because resistance coefficient and contact voltage higher, suppression spark favor. But for low-voltage motors , the excessive contact voltage to make it in the proportion of the total voltage drop is too large, so the use of metal graphite brushes .

Since the majority of structural defects brush , so researchers developed a second generation of electricity on the Capsule Slip Rings , slip ring to avoid the kind of brush structure of many shortcomings, such as easy to wear , not oxidation . As modern technology advances, brush slip ring technology has become increasingly sophisticated , just before the use of copper and copper ring brush contacts for signal and current transmission, relatively soft due to copper , rotation speed or when the use of time after a long , easily deformed , affecting close contact , thus resulting in distortion of current and signal transmission . Behind the development of precious metal brushes and copper rings to solve this problem , such as adding trace elements of the alloy conductive materials, rare earth metals, rare metals , etc., a good solution to this problem . Now, brush slip ring slip ring is still the main force of cost . Many large amount of manufacturers, both in the use of cost-effective electrical slip ring , especially equipment price is not high, the number of very large companies , due to cost reasons, brush slip ring is still their first choice.

China into the world's largest construction machinery market in the top 50 enterprises with 11

BEIJING, Oct. 16 (Xinhua) October 16, 2013 to 17, the global construction machinery industry 50 Summit Conference opened in Beijing. From the global construction machinery industry giant, with Chinese leaders to a top 30, with the world on China's economic development and long-term trends and industry towards in-depth discussions.
This global event is determined by China Construction Machinery Industry Association, the American Association of Equipment Manufacturers, Korea Construction Machinery Industry Association jointly organized by "China Mechanical Engineering" contractor. Has been successfully held twice, in the domestic construction machinery industry has been influential.
2013, the world is not only political and economic instability, and the global infrastructure highly relevant to the construction machinery industry, is also facing unprecedented challenges. In the first half, the world's leading manufacturer of construction machinery operating profit fell 42% deep, companies go through to take inventory and reduce costs accelerated way, boil degree "winter", further highlights the seriousness of the situation.
The same industry and windy weather, but also spread to China. At present, China has become the world's largest construction machinery market, with annual sales of more than 500 billion yuan (about 80 billion U.S. dollars). However, since 2012, China's construction machinery enterprises have experienced almost the same intensity of shocks. However, with 14 million people in this emerging market, "new urbanization" As soon as he asked the world to receive "a new round of investment is about to start" a strong signal that more and more eyes on China, more and more much hope placed in this market.
In the "China Construction Machinery" magazine recently released "2013 Global Construction Machinery Manufacturers Top 50", a total of 11 Chinese companies shortlisted. In recent years, XCMG, Zoomlion and so a large number of local enterprises through continuous booster technology accumulation, continuing to enhance product innovation, and ultimately on behalf of China's construction machinery industry the highest level among the world's leading camp.
As we all know, the demographic dividend, foreign trade and other traditional competitive advantage is changed, the whole of China is working to promote the upgrading of industrial innovation, and strive to climb the global value chain, the task more arduous and urgent. 2008 global financial crisis, China's construction machinery business groups, is by virtue of technology infrastructure and innovation, accelerating industrial upgrading, the process of integration into the global grand. In 2012, the acquisition of German Schwing XCMG, Zoomlion wholly owned CIFA, Sany acquisition elephants, it is leveraging technical innovation in recent years, Chinese enterprises to integrate global resources embodies.
At the meeting, China Construction Machinery Industry Association, Qi Chun speech said that the future for a long period of time, China will continue to grow as the world economic recovery and an important engine. With the world, especially China to further promote economic restructuring and industrial upgrading eco-system improvement, market competition environment and rule changes, growth rhythm adjustment, China's construction machinery industry in the development and growth mode quality, etc., will be leaps and bounds promotion.
Held in conjunction with the two parallel forum, with its more targeted and more in-depth topics set for discussion, which attracted hundreds of industry executives and the strength of the user. Among them, the "global excavator summit" in the industry stuck in a quagmire, when solving urgent emerged, the chain excavator individual interests of the Community, on this platform to express their views and seek common industry healthy, healthy and sustainable development the road. The "China lifting hundred Summit" is the first time in China's 100 most powerful lifting construction companies gathered a head with the manufacturer's representative depth dialogue to explore the road win.

Slip ring brushes and the oxide film

According to statistics, three relay pump operation has been burned eight switches. Collector ring temperature: brushless slip ring oxide film generally easier to form at about 70 ℃, when the collector rings, brushes overheating failure, usually at temperatures above 150 ℃, then even if the new ones brush, the oxide film is not easy to form, can not play the role of lubrication, brush wear will increase, resulting in the temperature continues to rise, become a vicious cycle. slip rings then you can take the external forcing cooling methods, such as Vaseline, high-power fan ventilation and other means, so that the collector loop temperature falls within the normal range for some time, so that the brush surface oxide film formed gradually make it into the virtuous circle. In addition, the rotor via a resistor, you can also speed. Compared with squirrel-cage motor, the motor is characterized by its complex structure, high cost, convenient operation and maintenance, maintenance workload. Collector ring pump relay switch model DW15-C630 type, wind slip ring rated current of 630A instantaneous stop 6300A, switching arc chute mutually insulated copper steel composition, arc performance is poor, relay pump the start and stop time will be in high temperature electric arc generated between the switch contacts, frequent start-term high-temperature heat generated by the arc degree of oxidation of the contacts increase, the contact resistance between the contacts increases, the main contacts of the switch firing sticky, damaged, or even cause the switch to an explosion, causing expansion of the accident.
