Shandong Grid Group Co

Mixed flow fan manufacturer, temperature between ℃ ~ ℃, dust does not exceed, humidity less than %, three-phase, power supply. The measurement pipeline for dynamic performance testing is made according to B standard. Make a test hole according to the standard and measure the pressure value with an inclined micro-pressure gauge. After calculation, the flow rate, total pressure and static pressure are obtained. Use a three-phase power meter to measure the input power, and use an atmospheric pressure gauge and a thermometer to calculate the air density during measurement. The noise test method is to measure the shell noise according to B "Noise Measurement Method of Fans and Roots Blower", and test in the vertical position of the fan shell.
The following is

A mixed flow fan is a fan between an axial flow fan and a fan. The mixed flow impeller allows the air to move both centrifugally and axially. The movement of the air in the shell mixes the two forms of axial flow and centrifugal movement, so it is called mixed flow.
< >Features
Mixed flow (oblique flow) fans have a higher coefficient than axial flow fans and a larger flow coefficient than centrifugal fans. They are used in situations where the wind pressure and flow rate are neither large nor small. It fills the gap between axial fans and centrifugal fans. It also features simple and convenient installation.
Mixed flow fans combine the characteristics of axial flow and centrifugal fans, and their appearance looks more like traditional axial flow fans. The enclosure can have an open entrance, but more often it has a right-angle curved shape that allows the motor to be placed outside the pipe. The drain shell slowly expands to slow down the flow of air or gas and convert kinetic energy into useful static pressure.
(B) series low-noise and energy-saving mixed-flow fan is a new type of fan between axial flow and centrifugal fans. It has the high pressure of centrifugal fans, the large flow rate of axial flow fans, and high efficiency. , good energy saving, low noise, easy installation and other characteristics. The fan design is novel, the structure is compact, the volume is small, the weight is light, and it is easy to install. The rotation speed is less than r and the noise is lower than B(). When the fan is connected to the pipeline and installed in the air-conditioning box, the noise is lower than B(). Low-pressure centrifugal fans are widely used in industrial and civil building ventilation and dust removal. < . >
