What is the correct installation method of Roots blower?

Many people will use Roots blower in their life. After purchasing Roots blower, they need to install it. Many people do not know about the installation of Roots blower. Now let's introduce the correct installation method of Roots blower. Let's get to know!

Correct installation method of Roots blower

1. Installation of power cord

First of all, when purchasing Roots blower for wiring, we should use 380V voltage according to the rated working voltage of the blower, instead of 220V working voltage. The wires shall not be reversed. If they are reversed, the fan will reverse.

2. How to select the correct installation platform

Generally speaking, the installation of Roots blower includes indoor installation and outdoor installation. First, let's talk about the indoor installation, which can be installed on the ground or on a platform. The details also depend on the site conditions when installing Roots blower. It is better to install it on the platform if it is outdoor, because there will be erosion on the ground, It will affect the normal operation of Roots blower.

3. Confirmation and submission of installed switches

According to experience, the switch should be set near the fan, which is easy to control. On the other hand, it can also deal with some emergency situations. If it is far away, once a fault occurs, the longer the delay, the greater the damage to Roots fan. Therefore, it is recommended to set the switch near the fan.

How to repair the Roots blower stuck

1. The gear is damaged

The normal gear blocking area is about 2/3 and larger than the meshing area. If the meshing force between gears is too large, the gears cannot rotate, and then the impeller will not move.

2. The rusted one is stuck

Roots blower has been idle for a long time, and rust will appear inside and outside. The rust will fall off in a large area, and the impeller may be stuck. In this case, it is necessary to use kerosene for soaking, gasoline washing, etc. to clean the rust, and adjust the clearance.

3. Foreign matter is stuck

When large particles enter the fan, they will block the gap between the components, resulting in the fan can not rotate. This requires cleaning the foreign matter in the cavity and checking the clearance between the impellers. At the same time, it is necessary to check the cause of foreign matter falling in, so as to avoid reoccurrence of fault.

4. Bearing damage

Roots blower has 4 bearings. If the bearing is damaged, the clearance between the impeller and the impeller, the shell and the wallboard will change, and the impeller will rub, causing the fan to not rotate normally. This is an indirect cause of the change in impeller clearance. This is also a common reason why the impeller cannot rotate.

5. Component deformation

Parts deformation caused by three blade roots blower is relatively rare. Roots blower manufacturers rarely reduce costs through components, and the strength of components cannot reach the standard. If the thickness of the casting is too thin and the journal is too thin, if the strength of the parts cannot reach the standard, the parts may be deformed, and the gap between the parts may be damaged.

The above is an introduction to the normal installation method of Roots blower. It is better to install Roots blower according to the correct method to avoid unnecessary situations.
