Currently, energy-saving method of adjusting stone processing enterprises older fans, the general throttle. When throttle farming fans, fan flow mainly large throttle valve or throttle damper adjustment to adjust the fan, even at low load than the throttle 50%, due to throttling losses and deviate from the high zone run, energy waste is very serious. And if you adjust the fan speed fan wholesale farming, both ports to cancel the throttling losses, but also to ensure the fan is always running in the high zone farming fans, it can significantly save energy. Adjust the fan speed can be said to run the fan is an effective energy-saving way, reflects the new trend of the current production of building materials industry. An 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, and has more than a trip value. b, the body's internal friction touch scratch or unusual sounds. c, either bearings or seals smoke phenomenon occurs livestock breeding fan, 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.
