Negative pressure fan installation precautions!

As we all know, the ventilation effect of the negative pressure fan is very good, but how to install the negative pressure fan to make the ventilation effect remarkable? The choice of the installation site of the negative pressure fan ventilation and cooling equipment is important. Try to choose the ground and platform. When the maintenance is performed outdoors, the motor needs to be equipped with a sunscreen to prevent exposure to sunlight. During the installation process, the wall on the side of the blower needs to be closed. In particular, there must be no gaps around the blower. The ideal way to install a negative pressure fan is to close the wall and nearby doors and windows on the side of the blower, and open the wall and doors and windows on the other side of the blower to ensure a straight flow of air. The installation of the negative pressure fan is a very important project, which has a great impact on the future use effect, and needs to be paid attention to during the installation process.

Before installation:

Before installing the negative pressure fan, carefully check whether the negative pressure fan is in good condition, whether the fastener bolts are loose or falling off, and whether the impeller collides with the hood. Carefully inspect the fan blades or shutters for deformation during shipping and damage.

When installing and selecting the exit environment, please pay attention that there are not too many obstacles 2.5-3 meters away from the exit.

installation time:

Stable installation: When installing the negative pressure fan, pay attention to the horizontal position of the fan, and adjust it to the horizontal position of the negative pressure fan and the ground plane. The motor must not be tilted after installation.

When installing, please place the motor's adjusting bolt in a convenient location. Adjust the belt tightness, easy to use.

When installing the support, it is necessary to ensure that the support and the ground plane are horizontal and stable, and if necessary, install angle iron next to the negative pressure fan for re-reinforcement.

After installation, check the surrounding for air tightness. If there are gaps, it can be sealed with solar panels or glass glue.

After installation:

After installation, check whether there are residual tools and garbage inside the negative pressure fan. Shake the fan blade by hand or lever to check whether it is too tight or rubbed to ensure that the rotating object is normal for trial operation.

When abnormal phenomena such as negative pressure blower vibration and motor humming occur during operation, stop the operation for inspection, and turn on the power after repairing.
