A brief introduction: What do you need to pay attention to when purchasing centrifugal fans?

Centrifugal fans can be used for indoor ventilation in general factories and large buildings, both for input gas and output gas. The gas conveyed should not exceed 80°C air and other non-spontaneous combustion, harmless to the human body, non-corrosive gas to steel materials, with good aerodynamic performance, smooth operation, low vibration, high efficiency, long life.

Our Kunshan Shengtang ventilation production of centrifugal fan products through the international Organization for Standardization 9001 international quality system certification, some products through the 3C certification and the national explosion-proof electrical products quality supervision and inspection center certification, users can rest assured in our company to buy!

Kunshan centrifugal fan

The following and Kunshan Shengtang ventilation together to understand the centrifugal fan selection need to pay attention to it!

1, can be distinguished according to the different grades of the fan, ordinary centrifugal fans are usually divided into high pressure, medium pressure, low pressure three. High pressure refers to when the pressure is greater than 2500Pa, medium pressure refers to between 1000Pa and 2500Pa, and low pressure refers to less than 1000Pa, we can use it in different industries according to its pressure. The power consumption of different pressure fans will also be large and small, so we should consider various aspects when choosing.

2, centrifugal fan safety factor reference index. In this case, we need to measure the air volume, wind pressure and error and loss of the fan, and now most of the air volume is 1-1.2, and the wind pressure is 1-1.3. Because the safety factor is too large, the centrifugal fan will run in the low efficiency area for a long time, resulting in waste and increase of energy. In addition, if the safety factor is too small, it will increase the hidden danger in the use of the fan, which is easy to cause production accidents and harm others.

3, the size and weight of the centrifugal fan. Due to different uses, the location of the installation is also different, which needs to be selected according to the local use. Choose a fan with high efficiency and light weight in the case of the same size, choose a fan with smaller size and light weight in the case of the same efficiency, and if the fan with larger adjustable range is more suitable in the same case.

4, pay attention to the size and structure of the model selection is consistent with the equipment, to avoid in the installation process, the fan aperture, hole distance, thickness and other size differences, resulting in installation can not be used.

6, the internal structure and material of the fan directly affect the performance and life of the fan, in the sample test stage should be fan performance or aging test, through the test to ensure that the fan can work under the required environmental conditions, and ensure the working life of the fan.
