　　　What is the role of vice impeller slurry (b)             Medium Heavy Plate

　　　In a typical mud pump, the power is always increasing with the increase of the flow rate, i.e., a power curve is increased with the increase of the flow curve, the use of the pump which creates a problem: When the pump design point operation, in general, the pump power is less than the nominal motor power, the use of this pump is safe; but when the pump head is reduced, the flow will increase (which can be seen from the performance curve of the pump), power also increases. When the flow exceeds the design point flow and reaches a certain value, the pump input power may exceed the rated power of the motor and cause motor overload and burnout. Motor overload protection systems running either pump action stops; either burn the motor protection system failure. Pump head is lower than the design conditions point lift used in practice are also often encountered a situation when the pump selection, mud pumps lift the election was too high, and the actual use of the pump is lower lift used; another case, in use of the pump operating point is determined not so good, in other words the pump flow require frequent adjustment; another is the use of a pump requires frequent change of venue. These three cases were strangers could affect the pump overload pump reliability.             Deformed steel bar
