A centrifugal blower emergency shutdown: During the unit test run, when any of the following circumstances, emergency stop immediately. Pressing the emergency stop operation is the main motor stop button, and then the rehabilitation work after shutdown. a, centrifugal fan sudden strong vibration Chengdu large centrifugal fan, and has more than a trip value. b, the body's internal friction touch scratch or unusual sounds. c, either bearings or seals appear smoke phenomenon, or a sharp increase in bearing temperature alarm value. d, oil pressure falls below the alarm value and can not be restored normal. e, tank level is low, there are cavitation phenomenon. f, shaft displacement values ??significant continued growth, reaching alarm value. 1. installation specifications centrifugal fan centrifugal fan installed, there should be a space for the installation site and the size of Nanjing centrifugal fans, centrifugal fans complete the required components should not have missed, including the support beams tripod ﹑ ﹑ ﹑ platform and boom fixing bolts or the like. 2. You must install a spring-type anti-vibration devices, rated deflection of 40mm. 3. Inter fan and duct flexible joints should be installed in Shanxi Fire centrifugal fans, fans at both ends should be run in parallel, if not parallel, the eccentricity can not exceed 25mm. 4. Only in the duct cleaned, filters installed, bearing lubrication good and after the end of the test, in order to officially start the fan. 5. When the fan during the field test, there must be beside the supervision and guidance staff, the amount of wind-site inspection in accordance with the measured value. Stand-alone operation of the test time was one hour, mainly for voltage, current, wind, air pressure, vibration and noise levels, etc. displacement test.
