What roots blower is good in China? Top 10 famous brands of roots blower manufacturers

At that time, I chose to compare for a long time, and then I visited a few on the spot, and finally bought Jingong's roots blower under the comparison in many aspects, because it was more moderate, and now it has been used for a year and a half, and there has been no problem. You refer to it, in addition to Jingong, Pepsi, Changsha you can also refer to the comparison, for this kind of equipment do not have to be nitpicky, the leather is durable.

Domestic, Pepsi, Changfeng, Jingong, Chuanyuan, Longtie, etc. are very good, and I personally think that Jingong and Pepsi are very good choices

In this case, as long as you choose a big brand, relatively speaking, you can achieve good results, and relatively speaking, it has a very good effect in use.

In general, there is no problem with this, because it is based on your own favorite style, as well as some of his design styles, because it is generally very good.

After many years of comparison of our use of fans, Hunan Changsha Changgu, Jiangsu Pepsi, Shandong Jingong, Zhanggu, etc. are good, among them, Jingong roots fan and Pepsi fan are relatively cheap, the quality is also good, we use a few times to understand.

Dear, I am happy to answer for you, the top ten famous brands of roots fan manufacturers A: 1, Shaanxi drum (China well-known trademark), Zhanggu (China's top 500 machinery enterprises), Changfeng (Hubei famous brand), Pepsi (Jiangsu famous brand products), Jingong (Shandong famous brand products), Shanggu (Shanghai famous brand) Wugu (Wuhan famous trademark). Roots blowers are small things, and these fans must be very good.

Shaanxi Drum (China Famous Trademark), Zhanggu (China's Top 500 Machinery Enterprises), Changfeng (Hubei Famous Brand), Pesset (Jiangsu Wangsu Province Famous Brand Products), Jingong (Shandong Famous Dry Ming Brand Products), Shanggu (Shanghai Famous Brand), Howden, Sanfeng (Hubei Famous Trademark), Jin Tongling (Jiangsu Famous Brand), Wugu (Wuhan Famous Trademark) 2, Changgu, Tiangu, Shanggu, Zhanggu, Pepsi, Jingong, Chuanyuan, Hengrong, etc.

1. The flow rate is different.

Because the screw blower has the characteristics of internal compression, the pressure of the air is established in the process of suction from the inlet to the outlet, and its leakage is stable and much smaller than that of the roots blower, and it can almost be considered that the flow rate of the screw blower is proportional to its speed, while the roots blower is approximately proportional to the speed. Therefore, the indicated flow rate of the screw blower product is the real flow rate of the outlet.

2. The characteristics are different.

The roots blower has no internal compression characteristics and has the characteristics of forced gas transmission; The screw blower has the characteristics of simple structure, continuous and uniform exhaust.

3. The principle is different.

The screw blower relies on the rotary movement of the rotor in the casing to expand and shrink the working volume alternately, so as to suck the gas and increase the gas pressure; The principle of roots blower is a rotary compressor that uses two vane-shaped rotors to compress and transport gas in relative motion in the cylinder.

Roots blower and screw blower are both common positive pressure fans, and the differences between the two are as follows:

1.The structural design is different: the impeller of the roots blower is mainly composed of two impellers that mesh with each other, and the impellers are equipped with several pressure converter cavities, and the air is processed through the impellers. The screw fan is mainly composed of a screw rotor and a stator.

2.Different accuracy requirements: Roots blowers require relatively high accuracy to keep the gas stable at high pressures, while screw blowers are suitable for a wider range and high pressure conditions.

3.The rated operating pressure is different: the screw fan is suitable for high-pressure working conditions, the pressure is greater than that of the roots blower, and it often operates under the excess pressure, and the roots blower operates in the ordinary pressure range, which does not exceed under normal circumstances.

In short, roots fans and screw fans have their own characteristics and advantages, and the use scenarios are different, so enterprises should choose products that suit their own needs.

Which fan Shaanxi drum brand is good in the roots group.

The roots fan is a volumetric fan, with impeller end face, front and rear end covers of the fan. The principle is to use two blade-shaped rotors in the cylinder to make relative motion to compress and transport gas or forest body rotary compressor. This kind of blower has a simple structure and is easy to manufacture, and is widely used in aquaculture aeration, sewage treatment and aeration, cement transportation, and is more suitable for gas transmission and pressurization systems in low-pressure occasions, and can also be used as vacuum pumps.

Roots blower is a kind of positive displacement fan, there are two three-blade impellers in the space sealed by the casing and wall plate relative rotation, because each impeller is the use of involute, or the envelope of the cycloid, the three blades of each impeller are completely collapsed and the same size, and the two impellers are also exactly the same, so that the processing difficulty is greatly reduced.

Working principle: the two impellers rotate in opposite directions, because the gap between the impeller and the impeller, the impeller and the casing, and the impeller and the wallplate is very small, so that the air inlet forms a vacuum state, and the air enters the intake cavity under the action of atmospheric pressure, and then, two of the blades of each impeller form a sealing cavity with the wallplate and the casing.

In the process of the rotation of the impeller, the air in the air intake cavity is continuously brought to the exhaust cavity by the sealing cavity formed by the two blades, and because the impellers in the exhaust cavity are meshed with each other, the air between the two blades is squeezed out, so that the air is continuously transported from the air inlet to the air outlet, which is the whole working process of the roots blower. <>

There are many roots blower brands on the market at present, but it may be difficult to list the top 10 brands here, because each brand has a different positioning and market. However, we can introduce some of the more well-known roots blower brands from the following perspectives.

First of all, we can introduce the history and quality of the brand. Some brands with a long history, such as Kaeser and Atlas Copco, are trusted by users for their high quality. Moreover, these brands have also done a good job in environmental protection and energy saving, and have been widely recognized by the society.

Secondly, we can introduce it from the perspective of technological innovation. Some roots blower brands, such as Siemens and Gardner Denver, continue to innovate in terms of technical expertise and introduce some products with their own intellectual property rights. These products have outstanding performance in energy conservation and environmental protection, technological advancement, efficiency and so on.

In addition, we can also introduce the roots blower brand from the perspective of market positioning. Roots blowers are used in many different fields, such as sewage treatment, environmental protection, steel, glass, pet food and other industries. In these industries, different brands of roots blowers have different market positioning.

For example, EDUR is a German manufacturer of water treatment equipment that offers a comprehensive range of pumps, especially in the marine and marine sectors. The roots blowers produced by Kärcher Energy in China are mainly used in waste sites such as excrement and garbage, and the market share is quite high.

In summary, when we introduce the roots blower brand, we need to consider it from different angles. Each brand has its own advantages and characteristics, and the top brands in China in 20 years are: Aidel, Zhangqiu Blower, Kaiser Rotz, Gardner Denver, Sweden Atlas Blower, Kärcher Energy, Yuntian Excitation, Guoxuan Hi-Tech, Synergy Blower, Taizhou Lishen.

We can choose according to the needs and attributes of the enterprise, and find the most suitable brand for roots blowers. <>
