Cause pump power is too large reason

If the power safety margin of the pump equipped motor is enough, and the motor is overloaded due to actual operation, the power consumption of the pump is too high. The reasons for large pump power consumption are: (1) the pump speed is too high; (2) the specific gravity of the liquid delivered exceeds the original design value; (3) the viscosity of the liquid being transported is large; (4) the size of the impeller is too large; (5) the resistance of the piping system exceeds or falls short of the predetermined value; 6) The pump head is too low, the flow is too large; (7) rotor parts and stator parts have friction; (8) bearing wear or damage; (9) mechanical seal seal seat pressure is too large; Rupture; (11) shaft bending; (12) uneven thermal expansion of different parts of the pump; (13) dynamometer is not allowed; (14) pump balancing device does not work. 【Print】 【Close】
