How to prevent sudden shutdown of Roots blower under load?

There is no good way to prevent Roots blower from power-off or shutdown due to other reasons under load. The main preventive measures are: do a good job of inspection and maintenance at ordinary times, and check the circuit regularly to avoid short circuit.

In some cases, temporary power failure may occur, which cannot be avoided. We can only do a good job in the protection of the fan, such as installing a check valve to avoid the reverse rotation of the fan. After installing a check valve, when the fan is suddenly powered off, the fan will not reverse and will not damage the whole head.

Sometimes the power failure of the fan can be controlled as usual. For example, if there is a typhoon passing by the local area, it is difficult to recover from the power failure. If there are frequent typhoons in coastal cities in summer and autumn, and the power failure cannot be controlled, then the Roots fan driven by the motor diesel engine can be used. When the power is cut off, the working condition cannot stop the oxygen supply, so it can be temporarily switched to the diesel engine for driving, Minimize losses.

Another is: standby machine. Generally, the company will prepare standby machine. When one machine is damaged, it will start the standby machine to ensure that the production line is not stopped, which can also reduce our losses.
