What are the technical steps for the commissioning and installation of Roots blower? Remember the following four points!

In order to ensure the smooth progress of the work, we must conduct commissioning before using Roots blower. Many people are right high pressure Roots Blower The commissioning of Roots blower can be divided into inching commissioning, no-load operation commissioning, full pressure commissioning and whole system commissioning. Today, I will introduce you to the debugging method of Roots blower.

1. Jog commissioning refers to completely separating the fan from the system on site and disconnecting the inlet and outlet pipes of the fan. Manually turn the gear, after confirming that there is no jam inside the machine body, start the fan, and then immediately shut it down, and then observe whether the rotation direction of the fan is the same as the rotation direction marked on the machine body. If it is different, for three-phase motors, exchange cables of any two phases and reconnect them. Because the structure of Roots blower cannot be reversed.
2. No load operation commissioning means that, on the premise of inheriting the previous step and confirming the correct rotation direction of the fan, start the fan, operate continuously for half an hour, and observe whether the fan operates stably and whether there is abnormal noise and vibration.

3. Full pressure test refers to the installation of a valve at the outlet of the fan (to avoid noise, a silencer is connected behind the valve). After starting the fan, a simulated load is applied to the fan by gradually closing the valve until the fan pressure reaches the pressure shown on the nameplate, and then the fan is operated continuously for about 2 hours to ensure that there is no abnormal sound, The temperature is stable (after the fan is pressurized, the temperature gradually rises, generally as short as half an hour, and as long as 2 hours. The temperature tends to be stable and stops rising. If it continues to rise, most problems exist), and the fan current is within the range shown on the nameplate.
4. The whole system test refers to connecting the fan into the working system and starting the trial operation, which shall last for more than half an hour. Since the design generally has design margin, after the fan is connected to the system, the actual operating pressure and current should be lower than the pressure shown on the nameplate. Overload condition often means improper selection, which requires strict troubleshooting and analysis.
The above is the debugging method of Roots blower. I believe you will know how to debug Roots blower after reading it. I hope it will help you.
