Roots blower test run for the new installation is not used for a long time repairs or blowers must be test run. Specific steps are as follows 1, in the no-load condition inching power switch Check the motor rotation direction. Indicating the direction of rotation required cooling shroud fan should open the cooling water valve. 2, starting 30 minutes after the air operation to check whether the abnormal vibration and heat generation if abnormal situation should identify the reasons for downtime. 3, no-load operation without exceptions gradually close the vent valve rated pressure to observe the fan temperature and vibration current, voltage is normal. 4, during operation on a regular basis to check the oil temperature, ammeter, bearing temperature usually 15 minutes thereafter. 5, shutdown must first relief, load shedding and then finally closed cooling water park. Structure a complete Roots blower fan is determined by the cylinder, the primary driven rotor, the main driven gear, side wall panels, a complete fan by the cylinder, the primary driven rotor, the main driven gear side wallboard, bearings, seals, safety valves, check valves, filters, flexible joints and other components.
