In the specific use of the plant, the negative pressure air will be centralized on one side of the industrial plant, and the air intake will be on the other side of the plant. The gas flows from the air intake into the machine and equipment, producing heat convection blowing.

Negative pressure fan

In this process, the negative pressure fan and the aluminum doors and Windows adjacent to the fan remain closed, driving the gas into the workshop through the aluminum doors and Windows on the intake side. The gas is injected into the workshop from the air inlet in an orderly manner, flows through the workshop, and is discharged from the workshop by the negative pressure fan centrifugal fan. The ventilation rate is as high as 99%. Through detailed project planning and ventilation speed and wind according to the actual demand, all the high fever, harmful substances, dust and smoke can be quickly discharged from the workshop, and all the problems of poor ventilation can be solved. The actual effect of ventilation can be reached within a few seconds after the fan is turned on.

How do you go about choosing the total number of installations you need?

1. First of all, you should consider that there is not a lot of pyrogen in the memory of the workshop where they must install the negative pressure fan;

2. Whether there is large smoke and dust in the workshop;

3. Whether the workshop has a good natural air supply environment;

The above three points determine the number and model selection of your negative pressure fans;

Most workshops are due to poor ventilation capacity, according to the aluminum doors and Windows themselves can not achieve efficient ventilation effect; Especially in the summer, stuffy weather, the room experience is best noticeable. The key to the installation of negative pressure fan is to exhaust more polluting dust particles out of the room through the negative pressure ratio of the fan, so as to effectively improve the office environment and make the indoor air quality cleaner and more transparent. Generally, when installing negative pressure fans, the priority issues of caloric value and pollutants are mainly taken into account. It is proposed that the key caloric value and environmental pollution of the workshop be discharged out of the room at the first time, so as to improve the actual effect of ventilation. This application can effectively deal with many problems existing in your current factory, such as very serious smoke and fine dust in the air.

The actual installation site will be determined according to the site installation standard; When you are dealing with heat, smoke and dust at the same time, it is generally recommended that the ventilation efficiency is not less than the normal ventilation every three minutes; According to this high efficiency to select the total number, generally in a certain range of total, but there are also relatively high requirements, a minute ventilation.

Industrial air cooler, as a cooling ventilation refrigeration machine and equipment, has been widely used in the workshop of the company. Today, the application industry is slowly expanding to greenhouse cooling and ventilation applications in some public places. Some small and medium-sized family industrial air cooler is suitable for home cooling and natural ventilation applications in summer and autumn. The following to understand the advantages of industrial air cooler in the refrigeration industry.

1, low power consumption, within the company's term of industrial air cooler power consumption is only one-fifth of the traditional central air conditioning, greatly saving the cost of the factory workshop;

2, according to the cooling water curtain to carry out heat transfer refrigeration, do not use air conditioning freon more refrigeration media, environmental protection and pollution-free in the process of use;

3. The cooling effect is remarkable with the faster cooling speed. The actual cooling effect can reach 5-10 degrees Celsius in the relative humid region, and the actual cooling effect can reach 10-18 degrees Celsius in the hot and dry region in the north.

4. Industrial air cooler can not only cool down but also carry out natural ventilation of indoor air quality, keep the gas clean and comfortable for a long time, will not cause the air conditioning cold of traditional central air conditioning, and there is no harmful whisk to human health;

5, in the operation of small vibration amplitude, low noise, large exhaust air volume, suitable for large and medium-sized workshop industrial plant cooling application;

6. The operation panel of the industrial air cooler is displayed by the LCD screen, which has the function of timing boot.

Nowadays, industrial air coolers have been common in every work, and when the application time arrives, there will be all kinds of minor faults. In fact, we can deal with them by paying attention to them and sorting them out on time when we use them. Here is the following I industry air cooler application notice!

Matters needing attention

Because the living environment of industrial air coolers is more complex (most often industrial plants), it is necessary to carry out maintenance to it to avoid some emergencies that cause damage to the quality of centrifugal fans and harm the operation. Maintenance of a little more, summarized as follows:

1, each wet curtain machine is suitable for 70-100 square meters of room temperature reduction. More than this standard value, it is likely that the actual effect will not be particularly ideal, and easy to cause equipment fatigue and problems.

2, when the air cooler is used, it is necessary to check whether there are any impurities such as shredded paper and dust in the wet curtain and reservoir. It should be cleaned up 1 or 2 times in the service life of the air conditioner every year. The water in the pool should be drinking water or other clean water.

3. The centrifugal fan is the heart of the air cooler. If there is a fault, the power supply should be turned off immediately and the electrician should be asked to repair it immediately. When assembling, attention should be paid to connecting the ground wire and disassembling the centrifugal impeller should be centered to prevent the leaf deformation from colliding with the shell.

4. If the air cooler float switch fails to operate and there is less water in the pool or overflow water seepage, it should be corrected and replaced in time.

5, if it is found that the wet curtain power supply is not enough or uneven, it is necessary to check whether the water storage tank is dry, whether the pump is running and the water supply pipe road and the water pump into the water part of the spray pipe road is blocked, and check whether the spray pipe road is located in the middle of the wet curtain. The normal relative height of sprinkling water can not be ignored, if the water level is too low, it may burn the machine.

6. When the air cooler is being repaired, the power should be cut off. After a period of time after the power is turned off, the static electricity will be released due to long-term use.

The above is the introduction of industrial air cooler application precautions, hope to be able to have some help.

First, reducing temperature can maintain the health of workers

In enterprises that are in continuous high temperature environment for a long time, there is a hidden risk of infection, especially in some positions where the occurrence of diseases is associated with prolonged high temperature. The main function of the installation of ventilation and cooling equipment in the workshop is to reduce the internal temperature of the workshop, ensure the physical and mental health of employees, and finally make employees more engaged in work, and promote the improvement of production efficiency of the enterprise.

Two, make the workshop beautiful and generous safety

Ventilation and cooling equipment in factory buildings are generally installed above the workshop. This installation method saves road space. Floor workers no longer need to use small and medium-sized floor fans to cool down. On the other hand, many enterprises are implementing the "6S" management method. The ground control is more standard and the enterprise "6S" work is more efficient, and the whole workshop is more beautiful and generous and safe.

Three, the control temperature can promote the increase of production

All walks of life in the production and processing of product quality is actually related to the environmental temperature, some equipment is not very sensitive to the temperature section, so in the usual production and processing is not very high in the pursuit of temperature, but for some relative high precision goods, slightly offset temperature will affect the quality of the product. Therefore, setting ventilation and cooling equipment in the workshop can control the temperature in the workshop, and then control it locally by comparing instruments, so as to further improve the qualified rate of products of enterprises. Therefore, high quality air cooler equipment can basically be linked with the economic benefits of enterprises. And some long-term factory buildings with industrial air cooler plants, from the technical retail price and not let the user unacceptable, in turn, let the user get the cost-effective is observable, such a result and cost-effective, of course, many shops can not refuse this kind of factory ventilation and cooling equipment.
