The first battle was successful, and the entire delegation of the Frankfurt International Machinery and Equipment Exhibition in China was jubilant.

More than 300 million US dollars of cooperation intentions were spread over the heads of more than 20 exhibitors, each of which also had a quota of nearly 20 million US dollars.

According to the pricing principle given by Fu Xin, each quotation is multiplied by two on the basis of the domestic market price and then converted the unit of RMB into US dollars, which is equivalent to six times the price, a huge profit, making everyone almost crazy! It's definitely a big deal!

Niu Guoqun was on the edge of the booth at this time, swept away the previous decadence, depression and depression, called people with flying eyebrows, and immediately made a billboard and placed it in the position that Fu Xin had applied for before - from the gate to the booth, on which it was written Hua Yaoguo's Mobao: How far is it from industrial modernization - only 500 meters!

If you haven't eaten pork, it doesn't mean that you haven't seen a pig run, this sentence may not be applicable in the 21st century, at that time many people have eaten pork, but have never seen a pig run, but occasionally use it for a use or okay, everyone understands what it means.

Niu Guoqun had never been a businessman, but he had seen on TV how those vendors sold things, and at this time he was holding a megaphone and a wooden stick in one hand, and a gong in the other, striking the gong with the wooden stick, and shouting in a Chinese with a strong Sichuan accent:

"Walk by, don't miss it, regret missing it! Don't miss the opportunity, don't miss it, time is not waiting for you! Ladies and sisters, aunts and uncles, come to China's booth to take a look, authentic Chinese industrial equipment, absolute quality and low price, Tong Suo is the best choice for developing countries to become powerful and rich people, and to catch up with the United States......! ”

Not to mention. Niu Guoqun did this, and a group of people quickly gathered around the booth. Although these people couldn't understand Niu Guoqun's words with a strong Sichuan accent, these people understood. This kind of performance method of Chinese, they have learned from some film and television works and literary works.

Onlookers are not unique to Chinese, in this world, everyone has the vice of onlookers! How can a society without curiosity progress? It's simple, right?

Putting aside the carnival of Niu Guoqun and others in front of the Chinese exhibition area, Fu Xin broke away from the team at this time and wandered alone in the exhibition area of the entire Frankfurt International Machinery and Equipment Fair, but at this time. He was approved by everyone in the entire Chinese delegation!

Fu Xin has changed his role at this time, from a supplier to a purchaser, and he needs to purchase a batch of equipment at this exhibition for the industrial technology upgrade of Huaxing Industrial Development Company.

"Hello, can you introduce me to your ventilation and dust removal equipment?" Fu Xin stood in front of the booth of the Japan Diamond Group and asked the staff of the diamond company inside.

The staff who received Fu Xin was a short uncle with an obscene image, which was very much in line with the image of the people of a certain country. Definitely authentic Japanese!

Hearing Fu Xin's question, the lewd uncle immediately asked Fu Xin with a smile on his face: "Dear Mr. Fu, my name is Saburo Inoue." It is a sales representative of a diamond company, it is a great pleasure to serve you, what do you need? ”

It is said that the enemy is the one who knows his own people best. This Saburo Inoue recognized Fu Xin at a glance. It's not as visionary as the two idiots of Louis and Toms, half a day. also gave some clues, but he didn't recognize Fu Xinlai.

"Oh, Mr. Inoue, I'd like to know more about your ventilation and dust removal equipment." Fu Xin didn't feel so surprised that this Inoue Saburo could recognize himself, he clearly knew how hostile the people of the island country were to China, and often, the people who knew him best were your enemies, and Fu Xin was very clear about this truth.

"Mr. Fu, please come with me." Saburo Inoue said with a huff, he took Fu Xin to the booth of ventilation and dust removal equipment, and began to introduce the models and parameters of relevant ventilation and dust removal equipment one by one.

Unlike the attitude towards African merchants, Japanese manufacturers are very enthusiastic about Chinese buyers.

In the past few years, China began to reform and open up, open up the market, vigorously engage in economic construction, need to purchase a large number of advanced equipment in the international market, and Japan's equipment prices are much lower than developed countries such as Europe and the United States, so Chinese enterprises have given up their hatred of Japan, Japan's machinery and equipment, has become the first choice for Chinese enterprises to procure.

Japan, a country that was defeated in World War II, was one of the countries that was able to start World War II after all. With the funds in exchange for spring and the technology that has been preserved, the country has begun to take off, and the people are still well fed and clothed.

Then, Japan has experienced 20 years of economic take-off, and at present, Japan's domestic industrial development has entered a plateau, the equipment market has shrunk, and it is eager to expand overseas markets. As a result, the economic and trade ties between China and Japan have become extremely hot.

To put it mildly, China in the 80s really had a kind of blind worship of Japan, and it was very friendly to this. The hatred accumulated in World War II is basically forgotten at this time!

"I need four types of equipment: centrifugal fan, negative pressure exhaust fan, fume hood and wet dust removal fan." Fu Xin took out a notebook and said to Inoue Saburo according to the contents of the notebook.

From the ventilation principle, the exhaust fan is divided into four types: high, medium, low and negative pressure, and the negative pressure fan series products are commonly used CAD/CAM design, which has low noise, low power consumption, large air volume, stable operation, long life, high efficiency, and has a louver automatic opening and closing system to achieve the characteristics of waterproof, dustproof and beautiful.

Negative pressure exhaust fans are widely used: negative pressure exhaust fans are installed outside the workshop window, and generally choose the downdraft outlet, exhaust air outward, and extract odor gas; It can be used in almost all places that need ventilation.

……

According to the principle of converting kinetic energy into potential energy, the centrifugal fan uses a high-speed rotating impeller to accelerate the gas, then decelerates and changes the flow direction to convert kinetic energy into potential energy.

In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, changes to a radial direction as it flows through the impeller, and then enters the diffuser. In a diffuser, the gas changes the direction of flow causing a deceleration, which converts kinetic energy into pressure energy. The increase in pressure occurs mainly in the impeller and to a lesser extent in the expansion process. In a multistage centrifugal fan, a reflux is used to bring the air to the next impeller, creating a higher pressure.

……

These two kinds of equipment need to be installed in Huaxing Electronics Factory, Huaxing Machine Tool Factory and Xunyang Electronics Factory. The following two are ready to be installed in the Huaxing laboratory.

……

Fume hoods are also called fume hoods and detoxification cabinets. Fume hood is the most commonly used local exhaust equipment in the laboratory, there are many types, due to its different structure, different conditions of use, its exhaust effect is also different. The performance of a fume hood depends mainly on the speed at which the air moves through the fume hood.

Most of the current fume hoods are made of wood, but there are also steel coated with epoxy resin, so this time we are looking for a fume hood made of epoxy steel. Common cabinet widths are 1200, 1500, 1800 and 2000 mm, 700-900 mm deep and 1900-2400 mm high. It can be used by 1-3 people at the same time, and the fume hood is generally installed against the wall.

In the middle of the front is a transparent door (mostly glass) that can be moved up and down, and the opening height is generally 100-550 mm.

Behind the door is the working surface for the experiment, with water pipes, sewers, power supplies, vacuum pumps, gas pipelines and other connections required for the experiment, and there are lights with protective covers for lighting. After the air is extracted by the exhaust fan at the front and top of the cabinet, it is either led to another place through the pipe, which is called full ventilation, or it is filtered and recirculated, and it becomes ductless ventilation at this time.

……

The vibrating wire filter plate for wet dust removal fan comprises a wire winding frame, six groups of spacers arranged symmetrically and in parallel and in parallel on the front and rear sides of the wire frame, and a metal wire wound on the wire frame and the spacer, which is characterized in that the wire is gradually wound in the direction of the outer layer from the wire frame to the outermost spacer, and the wire is gradually wound in the direction of the inner layer from the outermost spacer to the winding frame.

The dusty air is strongly sucked into the dust collector by the fan, and the fiber with the water curtain is attached to the vibrating wire filter plate that is sprayed by the sprayer, so that the dust is moistened and increased, condensed or retained, and the impact of the dust-containing gas makes the fiber vibrate, which strengthens the collision between the water mist particles and the dust in the gas, improves the capture rate of dust, and also improves the self-cleaning ability of the fiber of the vibrating wire filter plate.

After the dust-containing gas passes through the vibrating wire filter plate, part of it becomes water-containing dust particles and dust clusters, which are captured, flow with the water, and self-clean the vibrating wire filter plate; The rest of the dust particles turn into moist dust particles and dust masses through the water curtain, and after entering the dewatering device for treatment, the sewage is discharged from the sewage outlet, and the purified air is discharged from the exhaust outlet.

Fu Xin is a manager who is between a layman and an insider. said that he was an expert because he was an academician of the Chinese Academy of Sciences in his previous life, and he had a background as an all-round scientist and had his own opinions on some equipment.

He is said to be a layman because he does not have enough grasp of specific technical details, and he is far inferior to an old "expert" like Niu Guoqun, who has been groping in the field of five small industries for many years.

He came to Frankfurt this time, on the one hand, to sell products, on the other hand, to purchase equipment for his own use, both of which need to be planned, the former one, with the help of Hua Hongxing by his side, and the help of the Ministry of Foreign Trade, the Machinery Industry Committee and the following local enterprises.

The second item is because Fu Xin brought a notebook, which records the specific matters he needs to buy equipment. Basically, all the details, before Fu Xin came out, the relevant personnel of Huaxing Industrial Development Company gave him a piece of information, and Fu Xin could completely follow the above information to find the equipment needed by Huaxing Industrial Development Company.

The above information, Fu Xin does not have dyslexia, otherwise his identity as an academician of the Chinese Academy of Sciences in his previous life would really be in vain! (To be continued......)
