Transmission path and performance curve of anti-corrosion fan

During the operation of the anti-corrosion fan, it is necessary to pay attention to whether the external dimension and structure are consistent with the equipment, so as to avoid the dimensional differences such as the diameter, spacing and thickness of the anti-corrosion fan during the installation process, which makes it impossible to install and use. The internal structure and materials of the anti-corrosion fan directly affect the service life and performance of the fan. Relevant performance or aging tests shall be carried out on the fan in the sample test stage to ensure that the fan can work under the required environmental conditions and ensure the service life of the fan.

The model of anti-corrosion fan determines its performance curve, which can be divided into dimensional curve and dimensionless curve. The dimensionless curve is the basis for judging whether it meets the site requirements, while the dimensionless curve is the basis for describing the characteristics of the fan. The dimensionality represents the particularity and the dimensionless represents the universality. One of the flow coefficient and pressure coefficient can be used as the basis for calculating the fan number, the specific speed is the basis for selecting the fan model, and the internal efficiency is the basis for judging whether the model is a high-efficiency fan.

The main components of the anti-corrosion fan are made of FRP, which has good corrosion resistance and can be used for ventilation in corrosive environments such as petroleum and chemical industry. As long as the fan is in operation, it will produce certain noise. The basic control measures of noise are as follows:

1、 Control of noise source: the main noise source of the ventilation system is the fan. We can choose the anti-corrosion fan with low noise.

2、 Control of transmission route

1). Vibration isolation device: reduce the transmission of structural noise

2). Sound insulation device: reduce direct noise

3). Sound absorption device: improve sound absorption and reduce reverberation
