Generally, the Roots blower is not allowed to be reversed (because the gap between the air inlet and the exhaust port is different), so the Roots blower needs to be equipped with a one-way valve at the exhaust end. That is to allow the wind to be input from the Roots blower to the pipeline system to prevent the Roots blower from suddenly shutting down, so that the gas in the Roots blower system is affected by the system pressure, and the backflow impacting the Roots blower causes the Roots blower to reverse and damage the Roots blower. In addition, when several Roots blowers are running in parallel, if one of them does not work, the one-way valve can also prevent the gas at the exhaust end from passing through this unused Roots blower, causing its reverse damage. All in all, it is to protect the Roots blower from reversing. According to the structure form: vertical type, the center line of the two rotors of the Roots blower is in the same vertical horizontal plane, and the airflow enters and exits horizontally; the center line of the two rotors of the horizontal type Roots blower is in the same horizontal plane, and the airflow enters vertically and exits vertically. . The said Roots saw the fan blades of the machine collide, most of which are caused by the larger bearing clearance. If the replacement of the synchronous gear fails, it is recommended to use a bearing with better quality. The wear of high-speed bearings and Roots blower gears can be judged according to the gear occlusion clearance. If the gear wear exceeds the limit, the two synchronous gears can be turned over, so that the service life of the gears can be doubled. Measure along the length of the fan blade with a feeler gauge. If there is a problem with the Roots blower gear, you should immediately contact the maintenance personnel to repair it, otherwise it will affect the production and operation of the enterprise, and the Roots blower gear must be replaced in serious cases.
