1、 Overview:

The SWF series mixed flow fan has the characteristics of higher air volume than centrifugal fans, higher air pressure than axial fans, and can be installed axially. It is highly praised by users for its low noise, low power consumption, wide high-efficiency zone, convenient installation and use compared to centrifugal fans, and reliable operation.

2、 Characteristics:

1

The fan mechanism is compact, easy to install, and reliable to operate: the fan has a smaller volume than the axial flow type under the same air volume and pressure, and can be directly connected to the air duct. It can be installed horizontally or vertically, and is easy to operate and use;

2. Low noise: The casing of this fan has been specially designed to significantly reduce external noise. Under the working conditions of unit air volume and unit air pressure, the sound level can be reduced by 2-3dB (A) compared to A, and at lower speeds, higher fan pressure can be obtained. In the air supply and exhaust systems of industrial and mining enterprises and high-end civil buildings, low-pressure centrifugal fans or high-pressure axial fans can be replaced without the need for extensive noise reduction measures.

3. Wide range of use: This series of products is divided into two models: single speed and dual speed. The installation angle of the fan can be changed according to different usage scenarios, and the number of blades and speed can be adjusted to meet its usage requirements.

3、 Usage and maintenance:

Before installation, carefully check whether the fan blades and casing are damaged or deformed during transportation. If so, they should be repaired before installation; Check if the connecting bolts are loose. Before starting the fan, first check if there are any objects inside the fan duct that hinder rotation;

Check whether the insulation performance of the motor is good, and after connecting the power, check for friction, collision, and abnormal vibration;

There are many reasons for fan vibration, which can be checked from the following aspects:

The impeller rubs against the air duct and produces abnormal sounds and vibrations;

If the anchor bolts of the bracket are not tightened, significant vibrations may also occur;

The connecting bolts between the impeller and the shaft sleeve are loose;

Loose bolts connecting the bracket to the motor cause imbalance of the impeller and damage to the bearings, resulting in intense vibration.

If the motor temperature rises too high during operation at room temperature, it may be caused by a series of reasons:

The motor bearings are damaged, and the fit clearance is small, which does not meet the requirements;

The power supply voltage is too low or the three-phase motor is running out of phase.
