Many industrial fan is used in the factory, because the use of the environment is more complex, sometimes appear rusty phenomenon, so, industrial fan rust? Common cleaning way to what?

Let's look at the industrial fan rust

1, surface pollution: industrial fan attached to the surface of oil, dirt and other corrosive substances under certain conditions into corrosive medium, react with some of the steel, chemical corrosion and rust. This pollution the industrial fan surface of the rust in some places is more common, usually if the industrial fan surface on some materials such as oil, is very easy to cause the corrosion of industrial fan.

2, surface scratch: all kinds of scratches on the surface of the industrial fan damage, so that the protection ability of steel is reduced, easy to react with the chemical medium, produce chemical corrosion and rust. This is for stainless steel, some industrial fan design when the surface coated with a layer of anti-rust substance, if because of blunt cut this layer material, industrial fans lost to the outside world the diaphragm, the metal is easy to react with some substances in the air, so, industrial fan is easy to rust.

3, water contamination: water corrosion is one of the most common forms of rust industrial fans, especially when cleaning it is easy to leave some water in some corners, the water will accelerate the corrosion of industrial fans. This is especially common in places with heavy rainy seasons.

To solve this problem, industrial fan rust solution

1, physical method of rust removal

More commonly used method is relatively simple and crude is polished, this method requires some effort, rust can wear off, but it is not a good idea, if it is more about grinding affects industrial fan and beautiful, after advice to avoid this kind of method, or if you don't use the exterior trust of grinding can choose this way. You can use steel velvet, sandpaper, or a wire brush. If these are not available, you can also use some of the foil crumpled. If industrial fans have a thick layer of rust, you can begin with this kind of hard wire brush tool, as rust was scraped off again with mild tools, such as sand paper or steel wool, so as not to scratch the surface of objects, with the right tools plus some strength, the corrosion will be ground out of the industrial fan.

2, chemical method rust removal

(1) White vinegar rust removal: Common things in the kitchen have high acid composition, which can be used to remove rust. Unlike small items, industrial fans can be soaked in white vinegar. Because of its large volume, we can try to soak a cloth in vinegar, and then wrap it around the item for a few minutes. The damage to industrial fans is also relatively small.

(2) lemon derusting: if you don't want to use polishing or soak, and more like the natural method, then using lemon juice can also, put some salt in the region of the industrial fan rust and completely after besmear good fell on some lemon juice, now make it for two hours, if soak too long can damage industrial fans, after the invasion bubble brush a brush and rinse clean with water. The bigger advantage of using lemons can not only remove rust, but also won't have a very exciting smell after rust removal, but will be very fragrant.

(3) Baking soda: Not only does baking soda turn flat dough into delicious, fluffy bread, it's also a versatile toothpaste, unclogs drains, and can even remove rust. It's slightly corrosive, making it ideal for cleaning up rusty things. Put some baking soda in a bowl, add water to form a thick paste, wipe it in the area of rust, and let it stand for 2 hours, if you want to gentle treatment method after, you can use a wire brush, steel wool or brush to scrub, and then rinse with water and dried with a cloth.

The above is the summary of industrial fan rust how to do, rust causes and solutions of the whole content, we understand that the causes of rust are surface pollution, surface scratch, water contamination, common treatment methods are physical grinding, and white vinegar, lemon, baking soda and other chemical rust removal methods.

First, in terms of how it works:

The pressure of the air discharged from the negative pressure fan is reduced to the outside of the room, the indoor air becomes thinner, forming a negative pressure zone, and the air flows into the compensation chamber due to the pressure difference. In the practical application of industrial plants, the negative pressure fan is concentrated on one side of the plant, and the air inlet is on the other side of the plant. The air forms convection from the air inlet to the negative pressure fan. In this process, the fan close to the door inlet remains closed, forcing the air from the air inlet into the compensating side door plant.

The appearance of the industrial big fan adopts unique road flow technology, waterproof, rain proof, special motor and direct structural maintenance to improve the function, simplify the structure and reduce maintenance costs. Airflow shutters, no power consumption, no switch, can effectively prevent rain and invasion. Planned installations do not occupy windless space and can be installed anywhere.

The advantages of negative pressure fan are:

1. Good quality: it is a negative pressure fan produced by introducing German technology.

2. It's very convenient. A manual shutter controls the extractor fan, which usually operates without lighting and ventilation.

3. Low investment: the negative pressure fan has large air volume and wide applicable area, accounting for one-fifth of the total investment in air conditioning.

4. Simple: The suction fan is simple to operate, convenient to install, low maintenance cost, without professional maintenance.

5. Durable and corrosion resistant: negative pressure fan adopts heavy aluminum die-casting blade, resistant to high temperature, aging and deformation.

Now more and more enterprises are using environmental protection air conditioning of industrial buildings to cool down the workshop, because the cooling cost of environmental protection air conditioning of industrial buildings is very low, the power consumption of 1 hour is only 1 degree of electricity, but the cooling effect can reach 4-10 degrees, the cooling area can reach 100 square meters, in the same cooling situation and conditions, can be said to save electricity than the fan.

It was also because of this, so there are a lot of enterprise is very curious, industrial production, environmental protection air conditioning is done to such a low power consumption, also can achieve such a good cooling effect? Actually very simple, is the use of a phenomenon in our daily life to cool, industrial environmental protection air conditioning compressor, also do not need cold media, it is to use the principle of evaporation heat of cooling water, so we can do it at such a low cost, solve the problem of factory ventilation cooling.

As we in the hot summer, standing in the place where there is water will feel much cooler, because at the time of evaporation, water absorbs heat from the air, the temperature will be lower, and this is why where there is water will feel cool and comfortable. Industrial building environmental protection air conditioning internal use has four, it can increase the contact area of water and air, make water at the time of evaporation can be more fully absorbs the heat in the water, to achieve the effect of cooling and ventilation.

   The application scope of air cooler is very wide, widely applicable to workshops, factories, Internet cafes and other places in all walks of life. Cooling fan running at work, outdoor hot air through the filter unit, and then after wet shelter, cooling and oxygen is high, the strong cold air flow through the duct to the workshop, workshop space pure and fresh, ventilation cooling, air in air pressure increases the size of the old workshop through the doors and Windows, discharge, outdoor air in the workshop has air conditioning, About 20 times per hour or more of the overall ventilation of the workshop heat, dust, odor discharge, make the workshop air quality fresh, comfortable and achieve cooling effect.

    It is worth mentioning that the cooling effect of the air cooler is directly related to the air exchange rate. Compared with the traditional air conditioning, the air cooler has a very alternative unit, that is the air exchange rate. So does it mean that the larger the air exchange rate, the better? Of course not.

Different places, the amount of air change will certainly be different. In general, the required number of air changes is about 25-35 times per hour. The general place referred to here is the place where the flow of people is not very large and there is no heating equipment, such as the conference room. At this time, if you enlarge the number of air changes, it is a bit of a waste of suspicion. For crowded places, the required number of air changes is about 30 to 40 times per hour. If it is a production workshop with heating equipment, then how also need to have 50-60 times/hour air change.

    The energy-saving cold air machine mainly makes the air in the workshop timely update and conditioning to humidity, the improvement of air quality, and the human body can absorb fresh air in time. Thus determining human health. Let's start by understanding the sources of air pollution.

    Workshop air has two sources of pollution, it is people use carbon dioxide, from exhaled carbon dioxide concentration in the human body to nearly 40 times higher than the natural concentration in the atmosphere, when 0.2% of carbon dioxide concentration in the air, will constitute a harm to human body, the second pollution sources are machinery and equipment at work a smell to smell and the product itself, People have a kind of compliance with gas and smell fatigue phenomenon, living in the workshop for a long time, the indoor smell will not feel out, according to scientific experiments, in order to make the workshop gas does not exceed the degree of harm to human health, it is necessary to keep the workshop fresh air.

We use a 400 square workshop of 100 people to calculate, the general environment of the workshop requires air change 25-30 times/hour, and the crowded public places require air change 30-40 times/hour; In the humid southern region, the number of ventilation should be appropriately increased, while in the hot and dry northern region, the number of ventilation can be appropriately reduced. The air volume of the air cooler is 18000 cubic meters/hour, and the number of ventilation in the room (H-1)= the total air volume of the air cooler (m3/h)/[room area (㎡)× the height below the air supply port (m)]. (Usually the air nozzle will be two meters high, 400 square condition of the common configuration of cooling fan according to 150 square one, about three) H-1=[18000*3/ (400*2)] the result is 66 times/hour. This is enough to deal with the plant heat, smell, high temperature problems. Thus, the workshop environment is greatly improved, the enthusiasm of the staff is greatly increased, and the production efficiency of the staff is improved.

     Air cooler can solve the problems of sultry and peculiar smell for you. If you use fans and central air conditioning, it is impossible to solve this problem perfectly. Fan is short of refrigeration, ventilation and ventilation effect, is the wind blowing out hot, said the pack fan weather in the south is also can't do any improvement, with the high cost of central air conditioning costs, electricity is also a expensive digital, also cannot achieve the effect of ventilation and ventilation, because the central air conditioning is negative pressure, doors and Windows are closed. Air is not moving. So the cooling is fixed, but the smell is not. So no matter from which aspect to consider, the choice of energy-saving cooling fan is the most sensible.
