Method for increasing service life of high temperature pump :
1.Due to the pump operating at high temperature, so cold piping installation should be established bearing joints, piping to prevent displacement after warming.
2.Looking for coupling must be hot after heating in the pump body, in order to avoid the additional torque caused by operation.
3. When the pump starts, when the outlet pressure is formed, it is not blind to speed, in order to prevent the shaft or bearing premature damage.
4. The temperature of the heat medium jacket of the pump body can be slightly lower than that of the heat medium temperature of the front and back of the jacket. Because the melt viscosity and shear rate into a decreasing function, the gear extrusion, bearing the shear melt temperature will increase by 3 to 5 degrees Celsius, reduce the heat medium temperature can prevent melt degradation. Data show that by reducing the temperature of the bearing area, can greatly increase the bearing capacity, do not need to replace the large capacity of the pump, only by increasing the speed of the gear pump can be used to increase the output capacity of 50%.
