Overcurrent in the motor of 80AY60A
Thread Content
Will the absence of the impeller ring and the pump body ring in a single-stage centrifugal pump affect the current of the motor? The motor is 11 Kw.
The purpose of installing the lip ring is to balance the axial force; the inlet pressure of the AY oil pump is already high, and perhaps the manufacturer removed the lip ring for this reason. Under normal circumstances, if the mouth ring wears out, the current will increase
The impeller has an inlet ring; if the inlet ring of the pump body is removed, will it affect the current?
Affects the axial force distribution. The axial force is unbalanced; the bearing has to bear more axial force, which reduces its lifespan ； Secondly, it may lead to friction between the components, causing the current to increase and reducing the pump’s service life
The absence of a mouth ring or severe wear of the mouth ring leads to an increased backflow from the outlet to the inlet. As long as the process requirements are met, the actual flow rate of the pump increases, and accordingly the shaft power also increases.
The absence of an orifice ring leads to an increased volumetric loss in the pump, reducing its efficiency; to meet the required performance standards, the input power to the pump must be increased
