Analysis of the Heat Causes of High Viscosity Pump Motor

High viscosity pump has internal and external rotor, shaft, pump body, front cover, bracket, seal, bearing and other components. Sealing a mechanical seal and packing seal in two forms, for high temperature, high viscous density and corrosive media, the choice of packing seal. As the product can choose different materials and their unique structure, it is widely used in different nature, different viscosity of the medium transport. It will often appear in the actual future use of motor heating, the following we analyze the reasons for the motor fever: 1, the proportion of medium viscosity than high viscosity pump motor configuration? Configure the appropriate high viscosity pump motor 2, packing gland pressure is too tight or mechanical seal spring is too tight? Re-adjust the gland or mechanical seal spring compression 3, the use of the range (flow, lift) than the high-viscosity pump design requirements? According to the series spectrum selection of the appropriate motor 4, the pump assembly quality is poor, friction or motor and the pump shaft is not the same? Check the assembly quality, eliminate assembly problems? For the above conditions, one by one to do the analysis to find out the high viscosity of the motor motor overheating the real cause, in accordance with the corresponding fault, maintenance treatment.
