After the rotary fan is installed in
place, first remove the air inlet filter and pour about 30ml oil into the main
engine to make the engine oil evenly distributed in the main engine. Rotate the
main pulley by hand to make the engine oil evenly lubricate the inner wall of
the fan.
Before starting the rotary fan, please confirm whether the
V-belt is loose properly. If it is too loose, please adjust it. Make sure that
the relief valve is set at the specified pressure position. During
commissioning, the exhaust valve can be adjusted manually to increase the
opening pressure, adjust the safety valve and open it immediately. Before
starting the rotary fan, the sewage treatment tank must be filled with water
before the rotary fan can be operated. Otherwise, if there is no pressure at the
outlet of the rotary fan, the rotary fan will not be lubricated. Turn on the
power fan and confirm that the rotation direction of the rotary fan is
consistent with the rotation mark direction. In case of inconsistency,
disconnect the power supply immediately and adjust the motor wiring.
Observe whether there is pressure indication on the pressure gauge,
observe the oil dripping from the nozzle, observe whether there is oil flow in
the transparent oil return pipe, check whether all parts of the motor and fan
work normally, whether the temperature is normal, and whether there is abnormal
sound.
