Role of air-conditioning outlet
The outlet is one of the main components of central air conditioning equipment, the following combination of I Group is engaged in the industry many years of experience, to share
the role of under the air conditioning vent:
General outlet for the square diffuser, was the party line multilayer removable, generally canvas with fire connection, no filter; outlet vents, diffuser device of square or
circular, double-layer louvers or seam type outlet, the outlet is generally regulate air
Amount of size or angle of the blades, outlet air with the air conditioning system, generally behind it will not bring the filter surface is very clean, and may also send the cold
condensate accumulation in the above; return air is usually refers to the air conditioning return air,
Generally speaking, with the back of it will filter outlet surface there will be black dust in the corner, it is easy to distinguish; new outlet is a natural wind of the fan to the ceiling registers
outside directly to the desired area, generally with with the filter; outlet
Like a square diffuser, was the party line multilayer removable, general canvas with fire connection; send cold wind from time to time drops of water hung! Return air mostly
rectangular, said single (double) layers Louver, and with the filter; main role is to dirty
The air sucked back. The new outlet is small, each room wall-installation or linear outlet must be a new outlet is no doubt! The air vents are generally grille, install the outer
wall, the main role is to polluted indoor air into the room, fan coil unit system much more expensive than
Axial fan order to facilitate the construction of general machine mouth rounded metal duct connection!
The rainy season decoration pavement laminate flooring should be done to moisture work
The decoration of the rainy season will encounter a variety of problems, the best way is to lay-off, but many families start early and decoration company signed the contract, the agreed duration, so no one is unwilling to bear the risk of default. So how can we get very good results in the rainy season decoration? As long as the attention to the interference of the water renovation project, some projects, such as electrical wiring, do Door Chuangtao, as well as laying laminate wpc flooring.
Shop Laminate flooring to prevent moisture
Is generally not recommended to Shop composite floor to the rainy season, mainly because of the underground moisture can not volatile in a timely manner, if the keel and high water content can easily lead to moisture retention.
Once in the winter, laminate flooring moisture absorbed by dry air, likely to cause deformation or gap increase of laminate flooring.
Brush paint · water were
The basic principles of the rainy season is not painting. First, wood products, due to rain and humidity, water vapor re-painting to wood products, it is easy to water vapor wrapped on the inside surface of wpc wood products will be cloudy or whitish, followed by wall painting, even more serious consequences, because before the general paint, putty, if the wall is water vapor, it will cause cracks and other phenomena.
To buy materials and anti-rain
If you choose to buy a plate, you must pay attention to the anti-rain in the rain. Especially easy to absorb moisture materials such as wood, gypsum board, etc.. During transport if they get wet, the surface easy to residual water, coupled with high humidity in the air, can easily result in material deformation.
The health of pipe of copper pipes in the 21st centurys
Copper in the world s most authoritative institution, the International Copper Association has been committed to the promotion of copper pipes, to support scientific research on human health effects of copper on the environment. In economically developed countries abroad, the brass is already widely used. In China, with further deepening of the public health awareness in recent years the absolute number of brass, copper tube in China has developed very quickly, the market potential of the brass is being increasingly optimistic.
Major developers in the real estate industry was in full swing today, vigorously SOHO residential concept, intelligent furniture, household rooms, central air conditioning, green community card, smart consumers to shift the eyes to focus on a sound and real estate related to the "copper" element, which had aroused the attention of developers. In fact, the concern of the consumer for the copper is not a whim, but because of the copper in the residential electrical, plumbing, decoration, and have an extremely important role, more importantly, the use of copper can greatly improve on the details of real estate quality.stainless steel pipe fittings
The ancient Egyptians said that the copper as the ankh, which means "eternal life", which is a real name. Made of copper coins, containers, tools, and primitive weapons from our ancestors to modern copper producer, computer, Internet transmission cables, electronic parts, high-tech products of the collider, superconducting cable copper acts as a non- integral role. Modern homes, caring person and will find the Beijing Union Medical College Hospital, Shanghai Bund police capacity building complex, the western suburbs of hotel s long-standing villas, all with copper pipes. After seven or eight years of marshes, where the brass is still intact and normal use of this century, the "eternal metal, copper again in their own unique superiority.
As we all know, water pipes as a decoration in the hidden works, Concealed in the wall, because the water pipe carrying the flow of the body need to go through the test of time, especially hot water pipes, especially, several times a day through the 50 degrees Celsius temperature change Therefore, problems are often not easy to detect if it is found more serious, or too late feeling. Now brass in the decor market has been more and more people of all ages, because the risk factor of the hidden works great, the unique advantages of brass is a strong guarantee to reduce risk.
The advantages of a brass set of metal pipes with non-metallic pipe. First, it more than the plastic tube hard, easy to bend than the average metal, easy processing, has a certain resistance to frost heave performance; Second, brass with high pressure resistance, to ensure also able to maintain excellent performance even under high pressure , no distortion, does not rupture; Third, the brass heat-resistant refractory, still able to maintain its shape and strength at high temperatures, there will be aging, but not in case of fire, releasing toxic gases suffocating, while the performance stable, easy to corrosion, to reduce the resistance to the flow of the pipeline, to ensure the water flow, reduce water pressure on the wall; brass surface will form a layer of dense, hard layer of protection, whether it is the fats, carbohydrates, bacteria and bacteria, hazardous liquids, oxygen or UV can not pass through it, can not be steady erosion of its water pollution, parasites can not inhabit the surface of the brass to soften.
Be noted that copper welding process is safe, reliable, non-toxic, lead-free welding of copper does not pollute the water supply. Copper tubes are made from natural materials, excluding organic synthetic materials, processing, installation, maintenance or an accident may not cause harmful substances, is the real health and environmental protection pipe. These are other materials that can not be comparable, not only for the water supply system on the real estate, "insurance" that lets the user long-term use without worry.steel pipe fittings
It is brass and other types of pipe, these unique advantages, so in foreign developed countries had already been widely used. Building water supply system in the United States, Britain, the proportion of brass dosage, usually in more than 80%. In the United States for decades brass has been a water supply system dominated by the pipe, copper pipes installed in the United States in 2000 amounted to 3 36 million meters. 40 years since 1963 a total of already installed the 8.6 billion meters of copper pipes, this length can be 200 laps around the Earth. According to statistics, the total brass consumption point of view, the 2000 U.S. total brass consumption is 315,000 tons 333,000 tons, Europe, and our only 14,250 tons. In the gas system, the developed countries like the United States 70%, 80% in the United Kingdom, Australia, 95% of the indoor gas pipe with brass, and most of Buried.
At present, the water supply pipe in the residential construction there are basically six categories: galvanized steel, thin-walled copper tube, PP-R pipe, PVC-U pipe, galvanized liner PVC pipe, thin-walled stainless steel tube. The only thin-walled copper tube, PP-R pipes and thin-walled stainless steel tube can be used for residential hot water pipes. Currently on the market, the high price of stainless steel pipe, so starting from the economic point of view, the use of consumers and rare. Thin-walled copper pipe and PP-R pipe, although the price on the same grade, but the combination of comprehensive technical point of view, the advantages of the brass can not be ignored. Because, brass is a metal tube, suitable for dark set. PP-R pipes are plastic tubes, relative to the metal pipe in terms of its expansion coefficient, must be considered in the design and construction when the stretching deformation of the pipe; to ensure the number of pipe support bracket spacing to be small; heat source sufficient distance and other factors, useful life, brass water supply pipe is by far the longest useful life.stainless steel reduce
According to experts, the copper wall, sometimes the formation of verdigris patina the main component of the basic copper sulfate, basic copper carbonate, this patina is dense, and are linked closely with the copper substrate can play a brass good protection to prevent the substrate continues to corrosion. As we know, in the water supply pipeline, sulfur dioxide, carbon dioxide and oxygen content is minimal, and the ionization potential of copper in the water positive and difficult water H-ion replacement, it is difficult to form the patina, very resistant to corrosion . In addition, experts believe that even a small amount of copper ions dissolved in water is also beneficial to humans.
Now, with the further deepening of the public health awareness in recent years the absolute number of brass, copper tube in China has developed very quickly, the market potential of the brass is being increasingly optimistic. In Shanghai, for example, according to statistics, in 1991 Shanghai brass amount of 380 tons, 3050 tons in 1998, 2001, more than 4500 tons scale. In the high-grade building hot water supply systems, the application of the ratio of the copper tube more than 50%. According to market research, small-diameter thin-walled brass price is not high, supporting the connection method, the fittings are very safe and reliable, good hot water pipes in the current application.
We believe that our national brass awareness rising architectural design is moving towards the international trend, the copper pipes is bound to bring us the new concept of health in the 21st century pipe.
Cycloid gear pump and work Profiles
Including gear pump, the inner rotor driving wheel, the outer rotor is driven on the inside and outside of the rotor speed ratio i = Z1/Z2. Inner and outer rotor teeth have a tooth difference in the mating process of "secondary mesh". Can form a closed package fluid chamber. Meshing with the internal and external rotor rotation, all packets of fluid cavity volume changes in package liquid chamber volume from small to big, the cavity of the package solution to the partial vacuum, atmospheric pressure, the liquid stainless steel pipe fittingsthrough imports of pipe fittings into the pump chamber and the annular groove of the pump cover, began to aspirate. When the package liquid chamber volume to maximum, the suction end of the process. Package liquid volume of the cavity from the other annular groove by the drastic change hours, the package of the fluid cavity liquid pressed out, this is the pump discharge. In the course of their work, the pump inner rotor teeth turned a week, a work cycle, the completion of pumpingstainless steel clamps fluid to drain process. A rotor within the pump rotor one tooth per revolution must be the same with the above-mentioned chamber work cycle, the pump through a duty cycle continuous infusion outward, so the inside and outside the rotor around the two axes parallel to each other to do different speed, the operation will occur relative movement, this movement changing the space between the inside and outside the rotor, and connected with the suction drain Road in order to achieve the purpose of suction fluid.sanitary fittings
Collie Rick limestone superfine mill perfect interpretation of environmental protection and energy saving scientific connotation of
With economic development, environmental, energy conservation, environmental protection, "more and more attention. Industry colleagues to create huge economic benefits, but also inevitably to the environment a lot of pollution. Sulphur dioxide is one of the most important pollution Collie Rick limestone superfine mill desulfurization of thermal power plants, effectively reduce sulfur dioxide emissions.
Limestone superfine grinder limestone – gypsum desulfurization process is the world s most widely used desulfurization technology, flue gas desulfurization equipment used by the coal-fired power plants in Japan, Germany, the United States about 90% using this process.
Its working principle is: limestone powder made by adding water to the slurry into the absorber and the flue gas as an absorbent pump to full contact mixed flue gas sulfur dioxide and calcium carbonate in the slurry and the air from the tower lower part of the drum into the oxidation reactions that produce calcium sulfate, calcium sulfate reached a certain saturation, the dihydrate gypsum crystal formation.
Absorber discharge of gypsum slurry was concentrated, dehydrated, so that the water content of less than 10%, then use the conveyor to the gypsum silo stacked, after the desulfurization of flue gas after the mist eliminator to remove the droplet, and then through the heat exchanger after heating are from the chimneys into the atmosphere. Absorbent slurry in the absorber circulation pump cycle repeated contact with flue gas and absorbent utilization high and low calcium sulfur desulphurization efficiency greater than 95%.
With China s economic development, energy saving and environmental protection, green low-carbon new development model, the new industrialization of high technology, information covering a wide, good economic returns, low resources consumption, little environmental pollution brought into full play as the main connotations. Limestone superfine while on production mill is the perfect interpretation of the scientific connotation.
18 m dryer burst fire
Are using 18-meter-high Dryer to dry food, did not think things just happened, this is one of those present have a description. Dryer operation, or the quality of the dryer can not keep up. Either way, kilograms of grain almost disappears! This would also have to thank the Huai\\ an fire to grab a million pounds of food. Responsibility should be investigated! The fire happened!
The grain dryer caught fire in grain storage, grain dryer, there are more than 10,000 pounds of rice. Chuzhou District Fire Brigade received the alarm, and quickly dispatched fire-fighting forces rushed to the scene of the fire.
Firefighters rushed to the fire on the way, far to see the billowing smoke of the granary over. Firefighters arrived on the scene, continue to smoke was the top of the grain dryer, grain dryer rice was burnt crackling sound fire grain dryer is about 18 meters high, covering about 10 square meters the east is also connected with food storage, such as the fire is not timely control, the consequences would be disastrous.
For the scene, firefighters immediately started to fire-fighting operations, carry a water gun by two experienced firefighters climbed to the top of the dryer, use the water gun interdiction on the vents on the fire. After one hour the fire was successfully extinguished by firefighters struggling to fight the blaze.
Set up a yellow strobe alleviate congestion
Following the Last User \"rights\" with a reporter to experience Nanjing cantilevered traffic lights, a new hair in the Yangtze discussion of the \"Nanjing neighborhoods\" (http://bbs.yzwb.net) for the proposed post set off a discussion in the QQ group. \"Rights warrior\" Post said he is a graduate student in the school, are doing a Nanjing traffic optimization issues, and want you to take a Shaoshao Nanjing traffic. Soon, the speed limit on the digital \"can be sprayed on the road\" and \"Can a small part of the traffic intersection traffic lights changed to \\ yellow strobe\\ to become the most popular topics.
\"\\ Speed ??limit digital\\ sprayed on the road\"
Friends Mr. Huang recently just returned from Lianyungang back to Nanjing, but did not expect the car to open more than a decade, he has suffered a career drive \"most unexpected\" fine. \"It was more cars on the road, I then parallel to the right of a large van for a short distance.\" Mr. Huang did not think the van of this \"block\", Mr Wong did not know that they have missed the next the speed limit. Fined, but I did not might see that sign. \"Mr Wong told reporters that he had to drive to Beijing and Shanghai, in addition to the speed limit sign erected on the highway before, but also on the road to see the spray the speed limit mileage Arabic numerals. Mr. Wong suggested that after \"spray Nanjing highway speed limit mileage\" Arabic numerals, so that both the atmosphere and convenient.
To set up a \"yellow strobe
Nanjing lights is significantly more \"friends\" Tianshui \"professional reporters with a list of a series of numbers: about 7 km from the gate to the Hanzhongmen, there are 22 traffic lights. If each such as traffic lights have to wait for 20 seconds, that a total of more than seven minutes. In international practice road management system for the set of lights is clearly defined, such as London, England, the most central area, but only one ring of the intersection set, do not arrange the signal light on the road cross sections, re-dislocation design, ring, set the \"yellow strobe light, rather than signal to restrict the passage.
\"If some traffic junctions set the \\ yellow strobe lights\\ , it will greatly increase the accessibility of the road.\" Tianshui \"told reporters that\" yellow strobe is to tell the vehicle to slow down if there is no pedestrian crossing the road can be slow passing, instead of \"red light\".
However, the \"opposition\" to friends, \"Nanjing teacher\" as the representative of a prompt response. The Nanjing teacher, if the switch to the \"yellow strobe, is bound to increase traffic accidents. Because the driver\\ s driving this point not everyone will slow down the speed. Friends, \"Keep smiling\" proposed \"yellow strobe is only applicable to small cities, does not apply to Nanjing.
Authority to pay to respond to: I tried the \"strobe\" but ineffective
Nanjing Transport Authority staff told reporters that Nanjing is also sprayed on some highway speed limit number \"spray\" digital \"is not the qualitative requirements, if users who require more intense, you can add another\" jet speed limit figures \"the road. Also engaged in a yellow strobe light \"in Nanjing, but the effect is not satisfactory, the main reason is the future engage in traffic accidents increased.
\"First you want the driver to improve the \\ observation consciousness\\ .\" Nanjing Transport Authority staff said in a foreign country, the road not as good as the country wide, traffic is even greater, but lane order was very good. In the country, free to the driver\\ s lane change is very common, this is not only an important factor in causing traffic jams, but also causing traffic hidden dangers. Therefore, additional yellow strobe light, there is no such conditions in Nanjing.
