First, from the outer frame raw material differences: FRP glass fiber (glass steel), galvanized steel, plastic steel profiles;

Galvanized steel plate does not need to be introduced in detail. Many people have mastered it. Its advantage is economic and practical on ventilation and cooling equipment for the workshop.

Negative pressure fan of plastic steel profile raw materials: rarely used in the market at present;

FRP glass fiber negative pressure fan :FRP is synthetic fiber lifting plastic

FRP characteristics: (1) light texture and high toughness. (2) Corrosion resistance can be good. On air, water and general concentration of acid, alkali, salt and a variety of vacuum residuals and organic solutions are very good resistance. (3) Good electrical performance. Good cable sheathing raw material, used to produce processing conductors and insulators. High frequency can still maintain high quality dielectric positive charge. Microwave oven heating running stability high quality. (4) High quality temperature characteristics. FRP heat transfer coefficient is low, not easy to bend, because some to the workshop ventilation and cooling standards are relatively strict.

Because of the above characteristics of FRP, the negative pressure fan of FRP raw materials has high temperature resistance, corrosion resistance, light and strong quality, and longer service life;

Two, transmission system mode: the transmission system mode of negative pressure fan is divided into horse type or belt type.

From the perspective of the transmission system, the transmission system harms the air volume, noise, and maintenance of the centrifugal fan; Right away;

1. The blade of instant negative pressure fan is installed on the motor immediately to reduce the power consumption caused by transmission. For centrifugal fans with the same power, the air volume of instant negative pressure fan is about 10% larger than that of the belt type; After the belt of the negative pressure fan is loosened for a long time, the air volume of the centrifugal fan will be significantly reduced after it is loosened.

2. There is no noise caused by friction of the belt on the horse; Belt type to maintain, the general centrifugal fan belt can be used for 2 years (imported), a small amount of only by a year, especially in the air to install the negative pressure fan disassembly is also extremely difficult.

3. Motor: Motor is the cardiovascular of negative pressure fan. Belt motor general general motor (other manufacturers match special motor) and instant motor is negative pressure fan 12 extreme pollution resistance level above IP55 aluminum shell motor; The motor of the pressure fan

4. Fan blade: The fan blade of negative pressure fan is divided into aluminum profile, stainless steel plate, aluminum profile sanding process, titanium magnesium aluminum alloy aluminum alloy die casting, polyester cloth iron and raw materials. The difference of fan blade raw materials is determined according to the different sites used. The more common fan blade for aluminum profile, stainless steel plate, aluminum profile sand process blade. The fan blades of titanium magnesium aluminum alloy die casting are resistant to high temperature due to the characteristics of raw materials, relatively strong and not easy to bend and crack; Polyester cloth and iron fan leaves are used for strong oxidant places, general hot dip galvanizing plants with corrosion.

Negative pressure fan daily maintenance and solutions to common problems: no matter what commodity, the use of the whole process must be maintained and maintained, so that the service life of the product can be improved and it is difficult to cause common problems. Of course, the products of Runfeng frozen Equipment Co., Ltd. are not excepted. Although the quality of Runfeng refrigeration equipment Co., Ltd. is the representative, but good goods should also be appropriate operation steps, to love, so that the workshop ventilation and cooling can achieve good desired effect.

Workshop industrial air cooler is widely used in many large and small factories to cool down. Workshop industrial air cooler has the effect of diversion mild and natural ventilation, which is economical and practical. It can not only ensure the stable production and processing of the factory, but also reduce the cost and electricity consumption. Some large and small factories, such as thermal treatment plants, plastic machinery factories, leather processing plants, cooling, natural ventilation, odor removal effect is very good. In that way, what should be paid attention to in the selection of industrial cooling machine in Ningbo workshop of large, small and medium-sized factories? The use of Ningbo workshop industrial cooling machine, need to pay attention to the following points!

Cooling the workshop in summer is indispensable. Workshop industrial air cooler can solve many problems in different workshops, such as continuous high temperature, high fever, poor natural ventilation, much smoke, large taste and so on. It has the following advantages:

1. The specific cooling effect of the workshop is significant. The industrial air cooler in the Ningbo workshop can reach the cooling regulations in a short time, generally in 4-15 degrees, which is relatively fresh.

2, workshop industrial air cooler can not only quickly cool down, but also improve the relative humidity of plant air, ventilation, smell out.

3, effectively prevent a variety of infectious diseases in the green plant body, to avoid the growth of bacteria.

4, environmental protection, workshop industrial air cooler power consumption is low, is general central air conditioning 1/10, mechanical equipment refrigeration without air conditioning refrigerant, will not produce air pollution.

Advantages of industrial air cooler in workshop

Do you understand the benefits of industrial coolers in the application shop? Let's give you a simple explanation of the six advantages of the workshop industrial air cooler.

1, easy to assemble. Workshop industrial air cooler has no motor, no functional loss, no noise, small size, light weight, high efficiency of exhaust pipe, convenient installation. Save you a lot of manpower and material.

2, workshop industrial air cooler is durable, can operate for at least ten years, gain more than ten years;

3. When there is no electricity, the temperature difference and the blower are used to rotate the industrial air cooler in the workshop. Light wind or humidity alone can easily turn the turbine blades for 365 days, with no electricity needed. Fast response speed, save a lot of use costs;

4, high working efficiency, workshop industrial air cooler only needs a little wind blowing, to improve the working atmosphere and work efficiency of the factory is very effective. It will give you fresh air circulation and remove heat flow, organic exhaust or odors.

5. Durable. Workshop industrial air cooler select a whole set of sealed high-end rolling bearings, durable, without wetting.

6, widely used. Workshop industrial air cooler is widely used in agriculture, animal husbandry, industrial production, public places and other fields, to beautify the environment has made an important contribution.

Air coolers can't replace central air conditioning. Because of the limitations of the use of air coolers, it is decided that it can not replace the central air conditioning. From the historical development history of central air conditioning, it seems that the air cooler was the first and the central air conditioner finally occurred. Over the years, the air cooler has not been able to develop rapidly because it has been relatively limited in the whole process of application. At present, there are the following limitations in the use of air coolers:

1. Carry out refrigeration with the help of moisture evaporation heat absorption, which can increase the indoor air humidity when the temperature in the room is reduced to a certain extent; The area with special requirements for indoor air humidity, especially in the room is very rich in electrical goods should not be used;

2. The air cooler temperature reduction force is very limited, when the air cooler volume size and room size specifications are matched, the temperature reduction of 3~8*C can be generated for the room, the greater the natural environment temperature, the smaller the temperature reduction force;

3. Air cooler can be used after cold in summer, winter heating or pure electric heater heating or can not be used;

4. It is not suitable for high humidity weather in coastal areas and southern areas. And the central air conditioning can complete the adjustment of temperature and humidity, but also has the effect of air filtration and ash removal, it can meet the requirements of people's application is much larger than the air cooler.

What kind of industrial cold air mechanism cold? How about the cooling effect? The air cooler is not as cold as the traditional household central air conditioning outlet, but its outlet air conditioner is also cold. Generally in hot summer, the vent can be maintained at 26-29℃. Compared with outdoor 30-40 degrees of ambient temperature, the actual effect of temperature difference is more obvious, blowing comfortable and cool. So a lot of people are curious. Even if the actual effect of the air cooler is so good, is it used for refrigeration? Must the refrigerant Freon be added on time, as in traditional home central air conditioning?

Industrial air cooler (also known as evaporative air conditioning, mobile environmental protection air conditioning, water cooled air conditioning) is a kind of evaporative evaporative cooling natural ventilation generator set, which integrates natural ventilation, cooling, ventilation, ash removal, odor removal, humidification, and air oxygen content enhancement. It is a new type of industrial air conditioning and ventilation equipment with no refrigeration compressor, no refrigerant and no air conditioning copper pipe. It uses the basic principle of water evaporation to carry gas heat to complete the cooling, solving the problem of excessive discharge of traditional central air conditioning "air conditioning Freon". Wet curtain paper as a key component of refrigeration. When the water flows evenly down the wavy surface of the wet curtain from the top of the wet curtain paper, the wet curtain is evenly soaked from top to bottom. When the fan operation of the internal structure of the equipment causes negative pressure, driving the outdoor warm air of unsaturated fat through the wet curtain paper surface which is thoroughly soaked by rain, a lot of cold and humidity in the air will be converted into vaporization heat, so that the outdoor fresh air system into the equipment will drop from the dry bulb temperature to the humidity, thus increasing the humidity in the air. Air dry gas into clean and cool gas, with cooling and humidifying effect. Indoor humidity can be quickly reduced by 5-12℃, cooling faster, good air quality.

In fact, the key component of industrial air cooler accepted by the vast majority of customers here is the water curtain air conditioning evaporator (wet curtain), the most important cooling medium is water (municipal tap water can be used). General municipal water supply natural environment is similar, and this standard seems to be quantitative, the next is the wet curtain. If the refrigeration effect is obvious, the quality of the wet curtain must be good. Why do some people say that the refrigeration effect is not good after the installation of air cooler? If the removal of equipment failure, most of the reason is 99% of their own bought air cooler brand wet curtain quality is not good, water loss efficiency is very low, refrigeration refrigeration actual effect can not come out.
