A centrifugal blower emergency shutdown: During the unit test run, when any of the following circumstances Henan centrifugal fan, 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, 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, Henan centrifugal fan parameters, there cavitation phenomenon. f, shaft displacement values ??significant continued growth, reaching alarm value. (1) engineering design and the use of units based on the use of the characteristics of the selected type of fan sites Henan centrifugal fan centrifugal fan price, then according to the selected flow rate and total pressure centrifugal fan Henan customization, determine the fan number from the list and press the desired performance selection of motor power, except for motor performance specified in the table, there are other types of motors can also be selected, and when ordering. (2) The performance of the speed of each table is the most efficient performance tables within the range of 90% by traffic and other personality can be divided into four to eight points in the performance table when ordering prevail. (3) Fan qualified factory performance at a given flow rate under full pressure value does not exceed ± 5%.
