Multi-stage centrifugal blower: Start-up of multi-stage centrifugal blower
2020-11-22
Summary
In order to ensure the normal operation of the multi-stage centrifugal blower, we need to start it correctly. If the startup method is wrong, you will inevitably encounter some problems in the operation. Therefore, whether it is the preparation work before operation or the precautions during startup, or the detection during startup, it is to ensure the safety of use. Next, let us simply deal with it.

Therefore, whether it is the preparation work before operation or the precautions during startup, or the detection during startup, it is to ensure the safety of use. Next, let us simply deal with it.
1. check before starting the multistage centrifugal blower:
1. Check whether the protective cover of the air inlet is installed correctly, whether the installation is stable, and whether there is debris in the 3-meter-long wind of the air inlet.
2. Check whether the connection with the air duct is firm, whether the air duct joint is correct and whether there is air leakage.
3. Use a small wooden stick to pull the blade 2-3 turns to check whether it is flexible and whether it is stuck.
Normal startup after 2. check:
1. The multi-stage centrifugal blower shall be started intermittently. Do not start it at once to avoid the blower duct being blown off.
2. When there are more than two explosion-proof switches on the installation site, their use should be marked on the explosion-proof switch to avoid misoperation.
3. Move the handle of the explosion-proof switch to the forward position, connect the start button, and the local fan will start and run.
4. When two local fans are connected in series, you must wait for one fan to turn on and run normally before turning on the other local fan. It cannot be started at the same time.
3. observe whether the operation is normal:
1. After entering normal operation, check whether the operating sound of the multi-stage centrifugal blower is normal and whether the body vibrates.
2. After 10 minutes of normal operation, there is no abnormality, and then other work will be carried out.
3. Always check whether the ram is loose, squeezed, twisted, broken, dropped and leaked. If this happens, it should be dealt with in a timely manner.
The multi-stage centrifugal blower must be started without fail. Only in this way can we ensure its safe use. This concerns the safety of the operator. Therefore, it is necessary to operate safely when starting to avoid accidents. I hope the above methods and matters will be helpful to everyone.
