Roots blower test run for the new installation overhaul or blower must be unused for a long time commissioning. Concrete steps are as follows 1, under no-load condition jog power switch Check the motor rotation direction. Indicating the direction of rotation required cooling shroud fan cooling water valve should be open. 2, starts 30 minutes after the air operation to check for abnormal vibration and heat generation should be shut down if unusual circumstances pinpoint the cause. 3, no-load operation, no abnormal situation gradually close the vent valve reaches the rated pressure to observe the fan temperature and vibration current, voltage is normal. 4, the operation of the process on a regular basis to check the oil temperature, ammeter, bearing temperature is generally 15 minutes to check again. 5, shutdown must first relief, load shedding and then finally closed cooling water park. Roots blower impeller is a use compression to input and output of a wind instrument, and because of the different impeller can be divided into: two clover leaf blower and blower. The reason why is because the previous sub-blower impeller is cast into two, and now three impeller design than the original two leaf blower has a small vibration supply prices, low noise blower, gas ripple becomes small. Due to different application environments, we need to pressure the market to handle large traffic, then we classify the single-stage and two-stage blower blower blower manufacturers, single-stage blower is only one, and a two-stage is to have two sets of Roots blower series, twice in a row for gas compression. The demand for different phone manufacturers Roots blower, the different forms, we have direct connection with the associated blower and blower, direct motor and blower fan is directly connected to the main body to rotate with the United fans is the use of electricity Turn the machine pulley driven to rotate, and the rotation will drive pulley to rotate so that the host blower fan operation.
