4 advantages of air cooler

1. From a technical point of view, the power and cooling capacity of mobile coolers are basically the same as ordinary coolers. The difference is the design of air duct circulation. The air volume circulation of ordinary coolers is aimed at the indoor air circulation, while the mobile coolers reduce the indoor air temperature while sucking in fresh outdoor air to ensure the exchange with indoor air There will never be a "chiller disease". This fresh air duct design does not cause the indoor temperature to drop very low. In the case of an external temperature of 36 ° C, the indoor temperature is about 28 ° C, and the local temperature can reach 25 ° C. Consumers should be aware that the major feature of mobile air conditioners is that they can cool down in a local area when purchasing.

2. Because the mobile cooler is an integrated air conditioner, the noise is larger than that of ordinary air conditioners. With advanced noise reduction technology, TCL Delong has reduced the minimum noise of the machine to about 48 decibels, which is equivalent to the wind of a 2P cabinet. Main advantages 1. The cooling effect in the local area is faster than that of ordinary coolers. For example, to prevent overheating of computers, meters and other equipment, you can directly adjust the air outlet to the front direct blowing state to achieve the cooling effect.

3. It is not necessary to consider the location of the outdoor unit, as convenient as a fan, plug and play. For example, overtime workers in an office building only need to use hot air ducts to exhaust hot air to a distance and immediately have a cool space.

4. Equipped with Vientiane wheel, it can be moved to the place you want, which is more convenient and practical. For example: Whether it is a guest room or a kitchen, you can move as you like.

Several indicators in the application of negative pressure fan

The functional parameters of general negative pressure fans mainly include flow, pressure, power, efficiency and speed. The ratio of the fan's effective power to the shaft power is called efficiency. Negative pressure fan is based on the cooling principle of air convection and negative pressure ventilation. From the opposite of the installation site-the door or window naturally inhales fresh air, and the sultry gas is forced out of the room quickly. Any poor ventilation can be improved. Machine, cooling and ventilation effect can reach 90% -97%.

For the size of noise and vibration is also the main fan design index. Flow is also called air volume, which is expressed by the volume of gas flowing through the fan per unit time. Pressure is also called wind pressure, which refers to the increase in the pressure of the gas in the fan, which is divided into static pressure, dynamic pressure and full pressure; The input power is the shaft power.

The development of fans will further improve the aerodynamic efficiency, device efficiency and use efficiency of fans to reduce power consumption; replace large centrifugal fans with axial flow fans with adjustable blades; reduce fan noise; improve smoke and dust exhaust fan impellers and casings Wear resistance; realize variable speed adjustment and automatic adjustment.

The classification of fans can be divided into centrifugal, axial flow, diagonal flow and cross flow types according to the direction of gas flow. Fans are divided into axial flow fans, centrifugal fans, and oblique flow (mixed flow) fans according to the flow direction of the airflow after entering the impeller. Fans are divided into pressure type local fans and explosion-proof electric motors placed outside or in the flow channels, and explosion-proof electric motors are withdrawable local fans placed in explosion-proof sealed chambers.

How to solve the problem of running noise of negative pressure fan?

    For the negative pressure fan, what we will come to today is the analysis of the cause of its operating noise, and how to take necessary and effective measures for different reasons to solve it well, so that during the operation of the negative pressure fan To avoid this problem.
     
    The operation noise of negative pressure fan, and how to deal with it? For this question, the following Wuxi negative pressure fan manufacturer Hu Lin will give specific answers, so that everyone can thoroughly understand and master, so that they can be put to good use in practice.

     1. If the negative pressure fan is in contact with the window frame when it is installed too tightly, causing the window frame to resonate during operation, then its tightness or packing should be adjusted appropriately. For the bottom of the negative pressure fan, check whether it is stable. If it is not stable, then it is necessary to deal with it. In addition, the spring of the anchor bolt cannot be crushed to avoid problems.

     2. On the negative pressure fan base, the tightening degree of the damping pad or fixing screw is too high, so that it loses the vibration damping effect and generates vibration. At this time, the negative pressure fan base should be damped or fixed. Adjust the tightness of the screws to make them suitable, and restore the damping effect.

    3. The power supply voltage of the equipment is too low, so that the fan has abnormal noise or vibration. The solution is to control the power supply voltage within the rated range, and you can add a voltage regulator to stabilize the voltage. In addition, if there is collision or friction between the blades and the casing, this problem will also be caused. Therefore, the distance between the blades and the casing must be adjusted and controlled to avoid problems.

     4. In the negative pressure fan, if the impeller is not well assembled or the speed is too fast, it will also cause running noise. Therefore, to deal with it, the specific method is to reassemble the fan according to technical requirements, and adjust the speed of the impeller to make it within the appropriate range.

Analysis and solution of imbalance of impeller of negative pressure fan

Generally, the causes of imbalance of the impeller of the negative pressure fan in use can be divided into two types: the wear of the impeller and the scaling of the impeller. These two situations are related to the dust removal device connected in front of the induced draft fan. The cause of the imbalance of the impeller caused by the dry method is mainly wear, and the cause of the imbalance of the impeller caused by the wet method is mainly scaling.

As long as this happens, blade-like wear is formed at the blade exit. For the impeller wear caused by dry dust removal, in addition to improving the dust removal effect of the dust collector, the most effective method is to improve the wear resistance of the impeller. As a result, the operating costs of the negative pressure fan and the entire production system are reduced, and the overall benefit is very good. Analysis and solution of imbalance of impeller of negative pressure fan

协 The association force between these oxide scales and the surface of the impeller is not even. Some oxide scales will fall off automatically under the action of vibration or centrifugal force, which is also a cause of the imbalance of the impeller. A more practical solution is the thermal spraying technique, which uses special methods to change materials such as wear-resistant and high-temperature-resistant metals or ceramics into high-temperature and high-speed particle flow, and sprays it onto the surface of the blade of the impeller to form a layer of material than the impeller itself. Super-strong outerwear with abrasion resistance, high temperature resistance, and oxidation resistance.

湿度 The humidity of the flue gas purified by the wet dust removal device is very high. Although the dust particles that have not been removed are small, the viscosity is very large. When the departmental ash falls off under the combined effect of centrifugal force and vibration, the balance of the impeller is destroyed, and the entire induced draft fan will vibrate. Although this will increase the cost of manufacturing or maintaining the impeller, it will increase the service life of the impeller by 2 times and extend the overhaul period of the induced draft fan. Impellers that are not treated by thermal spraying during use can be considered for thermal spraying of the impellers during equipment maintenance.

Dry type dust removal device can remove most of the large particles of dust in the flue gas, but a small number of large particles and many small dust particles along with high temperature and high speed smoke through the induced draft fan, subject the blades to continuous washing. When selecting the induced draft fan, the dry dust removal should preferably use the impeller treated by thermal spraying. Because this wear is irregular, it causes the imbalance of the impeller. This can not only reduce the damage caused by the impeller's dynamic balance, but also reduce the imbalance caused by the oxide layer. When they pass through the induced draft fan, they will be adsorbed on the non-working surface of the blade under the action of the gas, especially at the entrance and the exit of the non-working surface, which will form severe dust fouling and gradually thicken.
