Reasons for high power consumption during the operation of fluoroplastic alloy chemical centrifugal pump and its treatment methods
(1) The impeller mouth ring is damaged by friction, and there is friction between the impeller and the casing. Treatment method: Check and repair or replace the impeller and mouth ring, and adjust the gap between the impeller and the object.
(2) The flow rate is too large during operation. Treatment method: close the small outlet valve to reduce the flow.
(3) The density of the liquid increases. Treatment method: Check the liquid density.
(4) The packing is pressed too tightly or rubbed dry. Treatment method: loosen the packing, check whether the cooling circulating water pipeline is blocked, and clear the pipeline.
(5) The bearing is damaged. Treatment method: Check and repair or replace the bearing.
(6) The speed is too high. Treatment method: Correct the pump shaft.
(7) The pump shaft is bent. Treatment method: Correct the pump shaft.
(8) The axial force balance device fails. Treatment method: Check whether the balance hole and return pipe are blocked.
