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 characteristics: a Roots blower, due out in the form of clover with a rotor structure and reasonable housing outlet structure, so the fan vibration, low noise. 2, the overall structure of the impeller and shaft and impeller wear, fan performance enduring, long-term continuous operation. 3, capacity utilization big fan blower where the best, high volumetric efficiency blower outlets, and compact, flexible installation. 4. Bearing Selection NSK, uniform bearing life, thus extending the life of the fan! 5, fan Viton seals made of imported materials, high temperature, wear and long life. Roots blower works: two clover-type impeller in the body by the action of synchronized gear engagement was in the opposite direction of rotation. Between the impeller each other, between the impeller and the casing, wall panels have adequate working space blower wholesale, they constitute the intake chamber and the exhaust chamber relative isolation. The use of the impeller rotation, after the body of the gas from the inlet chamber to the discharge chamber is discharged to push the body to achieve the purpose of the blast.
