Generator Blog

The magnetic generator is widely used in today’s life, because of its high efficiency, low pollution and low cost, it will become the most popular generator in the world.

The magnetic generator belongs to the next generation of energy devices and is more efficient than solar and wind. The use of magnetic energy is not a new idea, but it is being developed for a long time as a real and visible alternative to conventional methods. You know, any device that reduces our dependency on the utility companies that supply our electricity has got to be good news, and building a magnetic generator is the best way to cut our power bill.

As is known to all, magnetic generated energy is one the best forms of energy which is being used world wide, for producing this type of energy, all you need is a permanent magnet generator, this is a special energy system which does not need big investment, and a permanent magnetic generator can be easily built and the energy used will be free of cost, the working principle of a permanent magnet motor is very simple and the maintenance cost is very low, once it is installed, the generator can be used for a long period of time.

The magnetic generator is considered the greenest of all the alternative energy systems. Here are the main benefits of building a homemade magnetic generator:

l      By using it, you can practically eliminate your electric bill or at least reduce it significantly.

l      Unlike other devices, it doesn’t produce any noise.

l      It doesn’t allow any sort of harmful pollutants to spread into the atmosphere and it’s completely eco-friendly.

l      No climatic changes can have any effect on it, because it can work in all weather conditions.

l      It can fulfill the energy requirements of your entire home

l      It requires a very low maintenance.

Nowadays everyone is trying to find a renewable source of energy, which is environment friendly. The appearance of magnetic generator can solve the existing fault in energy generating system, and it is a second to none generator which can save a good mount of money by using it in our home or office. In a word, magnetic generator is the newest and greenest generator which can lower our bill cost and cause no harm to environment.

Before the connection between magnetism and electricity was discovered, electrostatic generators were invented that used electrostatic principles. These generated very high voltages and low currents. They operated by using moving electrically charged belts, plates and disks to carry charge to a high potential electrode. The charge was generated using either of two mechanisms:

·             Electrostatic induction

·             The triboelectric effect, where the contact between two insulators leaves them charged.

Because of their inefficiency and the difficulty of insulating machines producing very high voltages, electrostatic generators had low power ratings and were never used for generation of commercially-significant quantities of electric power.

With the rapid development of technology, all kinds of modern generators are invented and used in every area of our daily life, and there is a lot of enterprise involved in producing generator, these generators offer families and companies comfortable and convenient life, which is especially important in today’s life. For example, now Generac is committed to produce generator to residential, commercial, industrial, portable and RV.

Here are the structure of generator, a conventional motor is rotated by outside working, that is, transform electric power into mechanic power after power on; whereas generator takes advantage of the change of magnetic flux to produce sensitive electromotive, that is, transform mechanic power into electric power, while general conventional generator/motor is of rotation type, that is, all mechanic power output by rotation work, or generate electric by the work of rotation; the generator/motor in current market normally apply Faraday’s law or Lenz’s law as generating or driven principle

Solar generator is a kind of generator which produces electricity through the direct shining of sun upon solar panels, and the electricity can charge battery, which supplies power for energy-saving lamp, recorder, television, DVD, satellite receiver and other products.

Solar generator can be divided into several parts, solar battery components, charging and discharging controller, inverter, test instruments, monitor and other electrical devices. It has protective functions, for example, when solar battery component is over charging or over discharging, it has function of protecting itself, solar generator can produce direct current which is 12V and alternative current which is 220V, and it has small occupation of space, easy for taking and using.

Now we’d like to introduce the advantage of solar generator, the advantages are as followed.

1, it supplies power independently, and is not subjected to environment. It doesn’t need fuel and mechanical transmission component, it can be produced at a short period, so the scale can be at your will.

2, compared with fire generator and nuclear generator, solar generator doesn’t cause environment pollution, and it has aesthetical appearance, low fault, and long life.

3, it is easy for dismantling and installing, and can work on the move, so it cost lower in installation cost. Because it can be combined with building, we don’t have to bury electric wire.

4, it is widely used in all kinds of electric components, and is suitable for those families which are short of electricity, it can be used on electric component and lighting which is at countryside, hill, island, express way and other remote area.

5, it is eternal, as long as the sun exists, so we can invest money in studying it, but use the achievement forever.

6, the solar generating system can be listed form big ones to small ones. We can have middle power station which can produce 1000000KW, also generator group which can supply electricity for one family. It is incomparable.

The solar resource of China is abundant, so the potential development of solar resource is very broad.

Gasoline generator is a kind of generating device, it consumes gasoline as the main fuel, and a kind of device which turns other kind of energy into electricity energy. According to the survey of gasoline generator market, it is drove by turbine, diesel motor and other kind of motor, these motors can turn water flow, gas flow and energy which the burning of fuel and atomic fission produce into mechanical energy and transmit it to generator, then the generator turns the energy into electricity. Generator is widely used in agricultural and industrial production, military, technology and daily life. The price of gasoline generator depends on the model, different model has different price.

Here are the newest price table of gasoline generator in 2010s, the detailed information is as followed.

1, according to the survey of gasoline generator market, the price of 1000i frequency conversion gasoline generator is about 1900 yuan, it has four strokes and the power of it is 800W. although it is a bit of expensive, it has aesthetic appearance and makes low noise, which is suitable for place which need high request.

2, the 950 gasoline generator has two strokes and the power is 650W, which only costs about 600 yuan. But it makes higher noise, so it is not suitable for place which need high request towards noise and appearance. 3, the price of gasoline whose power is 650W is about 550 yuan, it will produce 0.6 degree of electricity per hour, and the fuel consumption is between 0.6 and 1 liter.

Now we’d like to introduce how to choose gasoline generator, 1, the generator whose power is 5000W is used to drive your computer, so in that way, it is comparatively inexpensive to use gasoline as the fuel.

2, we can compare apples with oranges, they are all useful for our daily life, in the same way, we can’t compare gasoline motor with diesel motor, they all have their advantages, but as is known to all, the price of common diesel price is higher than gasoline’s, on the contrary, the power which diesel generator can produce is more than gasoline’s.

According to the above situation, a kind of silent diesel generator’s price is about 6000 yuan, but if it is produced from foreign countries, it will cost more than 10000 yuan.

The LEAP-X style engine which is produced by CFM company is regarded as the first one of the third generation of civil aircraft engines, and it is composed of high pressure compressor, high pressure turbine and combustion chamber.

According to report, in recent days, American general electric company proclaims that they are considering offering aircraft engine to China’s undergoing research of civil large plane with group of seven summit in France. Now Chinese business aircraft enterprise is putting in a lot of energy in developing and manufacturing the newest single aisle aircraft which is called C919, and it chooses CFM’s engine as the only cooperative enterprise abroad, according to the estimation of Chinese business aircraft enterprise, in the following 20 years, there is a demand of approximate 2000 aircraft in global market, and CFM is committed to developing and manufacturing aircraft, now it has become one of the most successful aircraft enterprise in the world.

Here is the current research of developing LEAP-X style engine, at the present, the compress ratio of single-stage turbine in core machine is 16, at the middle of 2011, they will test the compress ratio of double-stage turbine and the initial stage of design should be done by the end of this year, then CFM will finally decide whether to choose single-stage turbine or not according to the analysis of data. CFM enterprise says that they want to have higher heat efficiency, and they increase that through the increase of core machine’s temperature, at the same time, ensure the efficiency of turbine and durability. They also want to do them best in the following aspects, firstly, compared with CFM56style engine which is assembled in Boeing 737 series airplane and Airbus A320 series airplane, the engine’s oil consumption of LEAP-X style engine reduced by 16%, if they combine new aircraft technology, the oil-consumption can be reduced more. Secondly, at the aspect of high bypass ratio in improving combustion efficiency, they try to increase it from 5.5 to 9, that is an amazing progress. Thirdly, decrease the weight of LEAP-X engine significantly. 

Electric motor is widely used in our daily life, without electric motor, we can barely live for months. People are becoming more and more dependent on using all kinds of electric motor to make our life easier and convenient.

Today we are going to talk about how to buy an agricultural single- phase electric motor. Agriculture is the foundation of Gross Domestic Product, in today’s China, there is still sixty percent of people farmers, so how to improve the yield of wheat, rice and all kinds of vegetable is an important and urgent problem which should be solved as soon as possible.

There are two tips for buying single-phase electric motor, firstly, we should choose the single-phase electric motor according to the spindle speed of agricultural machine. Generally, when the spindle speed of agricultural machine is high, we should consider buy double-stage single-phase electric motor, on the contrary, we should buy four-stage ones. Those high spindle speed machine, such as grind machine, centrifugal machine, seal machine and so on, we should choose two-stage single phase electric motor for it, and those machine which has low spindle speed such as squeezing machine, package machine, we should choose four-stage single phase electric motor for it.

Secondly, we should ensure the power of electric motor according its working load, for those machines which are engaged in machining of bean milk and machining of almond, we should choose single-phase electric motor whose power is between 800and 1100 W, we should consider buying double capacitance single-phase electric motor whose power is between 1500 and 2200W for machines which are engaged in grinding flour machine and squeezing oil machine, and so on. In order to realize various functions and exert the efficiency of agricultural machine, we should choose four-stage double capacitance motor whose power is 2200W; choose the electric motors which have good reputation and high quality; buy motors according to the rated current and current which circuit wire can take, the rated current on electric nameplate should be lower than rated current on board and circuit carrying current, if it is higher, then we can replace bigger electric board and thick wire; contact with agricultural machine manufacturer and ask them whether they can change for a new one.

Diesel generator is a small item of power generating device, it consumes diesel, and takes diesel motor as the prime motor to supply power to generator. The entire machine is generally composed of diesel motor, generator, control tank, combustion chamber, battery, protection device and other components. It can fixed on basic facility, or located, even for mobile use. Diesel generator belongs to these generating devices which can not work successively, if it has been working for twelve ours, its output power should be lower than rated power. Although diesel generator ahs low power, it is agile, convenient, and easy for operate and repair, so it is widely used by miner, railway, wild construction site, enterprise, hospital and so on.

In 1897s, the first diesel generator in the world is invented in Augsburg which is a province of Germany, and it is invented by Rudolf Diesel who is the founder of MAN enterprise, so the diesel motor is named as his name. MAN enterprise is still the biggest diesel generator manufacturer in the world, its generator can have a capacity of 15000KW, and it is the main power supplier in ocean shipping industry. Our country’s large-scale diesel generator depends MAN enterprise, such as Dongjiang electricity company in Guangzhou province, Fushan electricity company so on. Now the earliest diesel generator is still preserved in Germany’s national museum for exhibition. Now we’d like to introduce the working theory of diesel generator. In the combustion chamber of diesel motor, purified air which is filtered by air cleaning machine is well mixed with high compressed foggy diesel which is jetted through nozzle. Under the up-down compression of piston, the volume becomes smaller, and the temperature in the combustion chamber is rising so fast, when it reaches the burning point of diesel, the mixed air burns fiercely, and the volume expands, so it pushes piston down, in that way it makes the crank turning, because the alternative current generator is installed coaxially with crank, so when the diesel is turning, it drives the rotor of generator. Because of the electromagnetic induction, generator can output inductive voltage, and it runs through resistance, it will produce current.

The advantage of using diesel motor is that when the cost of fuel and working condition change, the change of fuel-consumption efficiency is flat. It is also famous for its reliability, durability, low poisonous air emission and wide range of use.

The generator group shoulders the burden of national economy and daily life’s electricity demand, in the future it will still play an important part for a long time. With the development of civilization and economy, the former generator group can not meet people’s need, so the trend of future generator group should be along low energy-consumption, environment protection, good looking appreance.

Nowadays diesel generator is widely used in daily life, so everyday we are involved in buying all kinds of diesel generators, but it is difficult for customers to buy a perfect diesel machine. This particle is focused on finding some tips for buying a perfect diesel generator.

Now the expert reminds customers to do the following things when buying a new generator, firstly, we should what band it is, secondly, we should know the manufacturing process, when we are testing the generator, we should watch whether the voltage and frequency is stable or not, whether the foundation of voltage is fast or not, whether the vibration is big or not, the size and color of engine’s smoke, and so on.

Here are the eight traps which we should consider when we are buying a new diesel generator.

1, we shouldn’t confuse the relation of KVA and KW. Sellers usually regard KVA as the overstatement of KW, and sell it to customers, actually, KVA is apparent power, and KW is efficient power, the equation is KVA=0.8*KW, generally, import generator group is using KVA as unit of power, but for domestic device, we use KW as a unit, so when we are calculating power, we should make 80% discount of KVA.

2, make a confusion between rated power and back-up power, when selling generators, seller only say “power”, and mistake back-up power for rated power on purpose, and sell it to customers. Actually, in generator machinery, we define that the power of diesel generator is larger than power of generator, because of the energy-consumption during the process. If seller sells it to customers for mistake, it will severely lower the life if machine group and bring high maintenance.

3, renew second-hand generator and sell it to customers, so when we buy it, we should caution and buy new one.

4, only tell the band of diesel generator, and do not tell customers the production place and the band of machine group, such as Sweden’s Volvo, Britain’s Stanford and so on, actually, any diesel generator group can not be fulfilled by one company, so customers should know the band and manufacturer of diesel generator.

5, do not talk about the band of diesel generator and generator, only talk about the price, that is absurd, which we should forbid.

6, do not talk about the condition of assembly, actually they are very important, which should be pointed in contract.

Nano technology is regarded as the newest technology in 21 century, we are experiencing high development both in theory and practice, large amounts of new nano material and components have been developed, and show unprecedented retrospect in biomedical, military and daily life, but a lot of researchers focus on developing nano component which has high sensitivity and high performance, few of them focus on power system under nano size, but the nano sensor which is used in biology and military has large demand for this system. Generally, the power of these sensors are directly or indirectly from battery, if these sensors can supply themselves with power ,and the size of component and power become smaller, that’s what scientist has been doing for a long time, but haven’t realized it yet.

The invention of nano generator is probably a new chapter in the development of nano technology, the reason is as followed, firstly, it realize the combination of semiconductor and piezoelectric for the first time, and make the foundation for exploring the physical law in this process, secondly, it offers the specific technical routine for the leap from nano component to nano system. The development and study of nano component is the most advanced area in contemporary nano technology, because nano component has small size component which can be minimized to nano stage, low energy consumption, high sensitivity which macro component doesn’t have. Thirdly, it makes the theoretical foundation for realizing the minimization of entire nano component’s working condition. Fourthly, it makes a new area for the application of sodium oxide, currently, there is a fiercely decrease in the quantity of the article which is about nano bar and nano wire, and how to apply these technology into new area is still a new challenge. Finally, sodium oxide  has the distinctive biodegradability and biocompatibility, so it is used to sensitive and micro system in human body.

Nano generator is the application of new nano technology which can afford itself energy, it uses distinctive method to gather energy from human body or external environment and supply it to nano component and system. It can turn mechanical movement energy( such as the movement of human body, the extension of muscle, the change of blood pressure), vibrate energy( such as sonic wave of ultrasonic wave and so on) and water pressure energy into electrical energy and supply it to nano component, this kind of nano generator offers the theoretical and practical foundation for nano robot and wireless nano component which can realize self-power supply function, but there is still a long way to go before the practical application of nano generator, so we should develop several nano wire at the first and develop key method and technology for different power at the same time, we should study the fatigue and life problem of nano wire, and how to change fluid energy and sonic wave into electricity efficiently through nano generator; we should solve the seal problem of nano generator and its interaction with different organism.

In a word, the invention of nano generator makes the foundation of realizing integrating nano component and actually nano system, and we look forward to the widely application of nano generator in biomedical, military and daily life.

Preface: scientist has produced soft power rubber, when fold it, it can transform eighty percent of mechanical energy into electrical power. We can use this kind of material to make shoes, clothing accessories, and daily used stuff, even we can implant it into body as power.

“This looks like a pair of shoes, actually it is a charger”, if we remake the movie nation-produced 007, maybe we will have this sentence in the movie, the shoes which is transformed into a fan in the movie has been out of date.

Now scientist has manufactured a kind of tiny generator which we can put it in the coat, fix it under the shoe pad, maybe years later, it is not that funny when we pull a piece of wire out of shoes and use it for charging mobile phone, nowadays with the development of micro technology and material, people can charge for device at any time.

At the early of 2008, professor Wang from Georgia university of science and technology makes a kind of material which can produce power, at the best case, this material can produce 80 MW at every square, under the microscope, we can see every group of electric material’s structure likes two curve cones, when the material is folded and shook, two cones are compressed together and produce electricity.

The theory for this generator is piezoelectric effect, just like lighter. In 1880s, curie and his brother found some crystal can transform between mechanical energy and electric energy. Now in our daily life, there is large amount of piezoelectric material, from quartz to small component in watch, from aerospace to deep ocean.

Piezoelectric material has a big family, they have the common aspect which is that the centre of electric charge is not always at the same position inside lattice, although it appears that it is neutral, but the micro deformation of shape can change the distribution of electric charge, and in macro aspect, it turns out to be current.

According to the assumption of Macarl, those devices which can product electricity with micro deformation can produce electricity through the deformation of lung when somebody is breathing, and they can supply power for pacemakers.

Now the researchers hasn’t tested the biological safety of this generator on animals yet, if it can charge for mobile phone or iPod, it can be counted as valuable products. With more and more low energy-consumption in electric device, we are becoming more and more reliable to portable equipment, this kind of soft generator can bring us more and more freedom in using portable equipment.
