According to the Ministry of Commerce, the WTO has released the world trade statistics report. From the global trade volume data, the world trade in goods and services nearly doubled from 2005 to 2015. After a modest rise from 2012 to 2014, world energy prices fell by 45 per cent in 2015. Regionally, Asia, Europe and North America accounted for 88% of the total trade in goods of WTO members, and the share of developing countries in exports increased from 33% in 2005 to 42% in 2015. Meanwhile, trade between developing countries rose from 41 per cent to 52 per cent in a decade. In terms of goods export, in 2015, the export volume of the top 10 countries accounted for 52% of the total export volume, while that of developing countries accounted for 42%. The total export volume of WTO member countries reached 16.2 trillion us dollars. In terms of service trade, the top 10 exporting countries accounted for 53% of the total export volume, developing countries accounted for 36%, and the total export volume of WTO member countries reached 4.68 trillion us dollars.

In 2015, according to the global trade volume data, world trade showed a weak trend -- the total volume of world trade grew at a slow rate of 2.7%, basically in line with the growth rate of world GDP (2.4%). However, as export prices fell by 15 per cent, the value of trade in goods (in dollar terms) fell by 13 per cent to $16 tn. World business services exports were $4.754 billion, down 6 percent year-on-year. The weak world trade in 2015 was mainly due to the economic downturn in China, the severe recession in Brazil, the sharp decline in the price of crude oil and other commodities and the unstable exchange rate. In 2015, the import demand of Asia and resource-based economies slowed down, while that of the us and EU strengthened.

The world trade volume data report said the total value of trade in goods was stable due to a stable dollar and a moderate rise in crude oil prices, but the outlook for the full year was not optimistic.

The big air industrial ceiling fans belong to a kind of ceiling fan which is produced by utilizing the dynamics of ambient air. It is highly praised by users in the market. The reason is that professional big air industrial ceiling fans aggregate various advantages and can effectively provide ventilation for a variety of different venues. Let's take a look at the main reasons for the popularity of the big air industrial ceiling fans.

First of all, this big air industrial ceiling fan is cost-effective and energy-saving. Although it is a high-tech ceiling fan, the design of energy-saving and environmentally friendly materials will not be too high in price, and the low speed will not cause users to consume high power. Moreover, it has a long life, so it is more cost-effective and more popular with users.

Then, the big air industrial fan run very smoothly and are safe to use. All kinds of fasteners are one-piece installation. Moreover, this ultra-large energy-saving ceiling fan can run continuously for a long time, improving the space environment for users. It does not cause the motor to overheat and malfunction due to long running time. The ceiling fan itself has a cooling function, and the low speed operation does not cause too much heat, so users are willing to choose.

Every summer is the season of trouble for major factories and workshop managers. Why are we saying this? The current workers' treatment requirements have been improved, and the work environment without central air conditioning or environmental air conditioning work has caused a shortage of employment. The installation of central air-conditioning will increase the cost of corporate expenses, which is a lot of money. Not every business can afford the cost of expensive central air conditioning. What about the large workshops where air conditioners cannot be installed? The times are changing, is technology solved?

Our company believes that business owners can install big air industrial fan for their own factories and workshops. This is the best solution for both. Compared to central air conditioning, the cost of installing big air industrial fan is much lower. So what are the advantages of large industrial fans?

When choose industrial fans, the user maybe confused, and do not know which kind is better. While a good industrial fan is not only meeting performance requirements,but also involving safety and noise.

Five safety standards for large industrial fans as follow:

1. Check whether the motor head and the whole machine will shake when rotating in low and medium speed gears, especially in high speed gears.

2.After a long period of high speed rotation (at least 1 hour later),perceive the heat generating from the front shell of the industrial fan by hand or other instruments. If it feels very hot, it indicates that the industrial fan motor has poor heat dissipation performance.

3, look at the speed, power, air volume, noise and other parameters (industrial fan speed, power, air volume and noise is proportional, that is to say, the higher of fan speed, the power and air volume are greater,  the noise will also become larger,part ventilation cooling effect is better).

4, see whether there is intermittent pause in high speed rotation around the head, whether the head is not in place.

5. Gaxiao industrial fan is designed with brand-new mortise and tenon structure connection mode, which has the function of real anti-collision.

Then, we need to observe the industrial fan noise. What are the sources of noise?

1.Vibration. If the rotor of the fan rotates, the rotor's physical center of mass and the center of inertia of the rotating shaft are not on the same axis, it will lead to the imbalance of the rotor.The close distance between the physical center of mass of the rotor and the center of inertia of the rotor is called eccentricity, and the imbalance of the rotor will result in eccentricity. When the rotor rotates, a force acting on the support of the rotor will be generated due to the action of centrifugal force, resulting in vibration, and vibration will be transmitted from the base path to all parts of the machinery.

2.Wind noise. At the rotating of large industrial fans, the blades are periodically subject to the pulsating action, resulting in noise;On the other hand, the blade itself and the pressure on the blade are not evenly distributed, so it is easy to disturb the surrounding gas and parts during the rotation, which also constitutes the rotation noise.In addition, vortex noise is generated by the pulsation of pressure distribution on the blade , which is due to gas flowing through the blade generating the turbulent attachment layer, vortex and vortex separation.The noise of these 3 reasons can be called  "cut wind noise", the fan with general wind & big wind pressure, its cut wind noise is bigger also.

3. Abnormal sound, wind noise sounds like just the wind, but the abnormal sound is different, during the rotating of industrial fan, if except to the wind, there are still other sounds, you can judge the industrial fan has abnormal sound.Abnormal sound may occur due to foreign matter or deformation in the bearing, collision for improper assembly, or uneven winding of the motor resulting in looseness.The service life of fan is working time of radiator product working normally without breakdown , high grade industrial fan use life can achieve tens of thousands hours commonly.

The size of noise when the fan works, affected by many factors, the unit is decibel (dB).When measuring the large fan’s noise, it shall be carried out in the muffler room with noise less than 17dB, one meter away from the fan, and aligned with the fan's air inlet along the direction of the fan shaft, and measured in A weighted way.

4. The spectral characteristics of industrial fan noise are also very important. Therefore, it is necessary to record the noise frequency distribution with a spectrograph. Generally, the noise of the fan should be as small as possible and there should be no abnormal sound.Fan noise is related to friction and air flow.Fan rotate speed is higher, wind quantity is bigger, the noise that causes also can be bigger, the element of fan’s vibration also cannot ignore additionally.Of course, a high-quality fan will have very little vibration of its own, but the first two are difficult to overcome.To solve this problem, try using a larger fan.In the case of the same air volume, the working noise of the large fan at a lower speed should be less than that of the small fan at a higher speed.
