How to improve the pump life
1, due to the high-temperature oil pump body running at high temperatures, it should be installed on the pipe when the cold installation hinge support seat to prevent the pipe after heating temperature. 2, the coupling must be heat pump after heating to find the correct, in order to avoid running additional torque. 3, CQB-G high temperature magnetic pump outlet pressure measuring point to set the interlock to stop the alarm, otherwise, once the discharge pipe blocked, easy to cause damage to the pump. 4, high temperature pump start, no pressure in the export formation, you can not blindly speed, to prevent premature failure of the shaft or bearing. 5, cleaning pipetting, do not pump delivery of cleaning fluid, the inner part should be removed, pipetting after the end of installation, so as to avoid foreign matter in the pump. 6, the temperature of the jacket heat medium jacket can be slightly lower than the jacket before and after the heat medium temperature. Because the melt viscosity and shear rate as a decreasing function, the gear extrusion, bearing shear will make the melt temperature rise after the pump 3 ~ 5 ℃, reduce the heat medium temperature to prevent the melt degradation. Data show that by reducing the bearing zone temperature can greatly increase bearing capacity, do not need to replace the large-capacity pump, just by increasing the speed can be used gear pump output capacity increased by 50%. 7, speed to be slow, do not make the sharp rise in pressure before and after, in order to avoid damage to the bearings or melt blocked the lubrication channel. 8, high temperature pump outlet melt filter to be replaced on a regular basis, do not long-term high pressure and pressure limit operation. 9, Regular replacement of bearings can save maintenance costs. When it is found that the amount of wear on the inner surface of the shaft or bearing is close to the thickness of the hardened layer, the shaft can be polished and reused, replacing only the bearing. This prolongs the life of the shaft by 8 to 10 years. 10, in case of power outage or heat medium cycle interrupt more than 3Omin, the pump should be disassembled after cleaning reassembly, in order to avoid melt curing, cracking and other caused by poor bearing lubrication and high temperature pump damage.
