Trefoil Roots blower Slowly open the exhaust valve to fully open when shutting down. Press the stop button on the electric cabinet. Personnel replacement. high pressure Trefoil Roots blower is a volumetric compressor, which can change the flow and shaft power by adjusting the speed. The pressure gauge switch is in the normally closed state. If you need to measure the pressure, you can open the pressure gauge switch. Note that before pressing the start button, be sure to check whether the outlet valve of the fan in operation is open, and whether the fan pressed the start button is consistent with the actual fan in operation. When the high-pressure roots blower needs to operate, it is necessary to turn the corresponding blower switch on the electric cabinet to the working position, and then press the start button, and turn the switches of other fans and frequency converters to stop. After the fan operates normally, close the exhaust valve slowly to avoid burning the motor due to excessive instantaneous current of the fan due to too fast closing. Adjust the air inlet valve contacting the oxidation tank during operation to ensure uniform aeration.

   

Problems needing attention in starting and closing three blade roots blower

1. Preparation before startup:
(1) Check the connection tightness of bolts and nuts.
(2) Check the lubrication condition of the reducer to make the oil level at the center of the oil pointer.
(3) Check Trefoil Belt tension and pulley deviation of Roots blower.
(4) Check the voltage and frequency of the power supply;
(5) Check whether all instruments are normal, and inform the maintenance personnel to replace them in case of any abnormality.
(6) Open the main valve on the pipeline and the outlet valve of the fan to be operated, and the outlet valves of other fans not in operation are in the "closed" state to avoid overload operation of the fan and damage to the machine

Note that the switches of other fans are in the "stop" position. Before turning the switch to the "frequency conversion" position, be sure to check whether the outlet valve of the operating fan is open, and press the "frequency conversion" button Whether the fan of the button is consistent with the actual fan.
(3) After the fan operates normally (usually 1 minute), close the exhaust valve slowly to avoid burning the motor due to excessive instantaneous current of the fan due to too fast closing.
