(I), 2CG high temperature gear pump pump body running at high temperatures, so cold installation piping should be set hinge support seat to prevent pipe displacement after warming. Ii, the coupling must heat the heat after the pump to find the correct, in order to avoid running additional torque. Iii, 2CG high temperature gear pump outlet pressure measuring point to be set to stop interlocking alarm, otherwise, once the discharge pipe blocked, easy to cause damage to the pump. Iv, 2CG high temperature gear pump start, no pressure in the export formation, you can not blindly speed, in order to prevent premature failure of the shaft or bearing. ㈤, cleaning pipetting, do not use 2CG high temperature gear pump conveying cleaning fluid, should be removed within the pieces, pipette after the end of installation, so as to avoid the pump mixed with foreign matter. ㈥, the temperature of the pump heat medium jacket can be slightly lower than the heat medium temperature of the jacket tube before and after. 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%. ㈦, speed to be slow, do not make a sharp rise in pressure before and after, so as not to damage the bearings or make the melt clogged lubrication channel. ㈧, melt filter behind the pump outlet to be replaced on a regular basis, do not long-term high pressure and pressure limit to run. ㈨, 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. ㈩ In case of power outage or heat medium cycle interruption more than 3Omin, the KCG high temperature gear pump should be disassembled and cleaned and then reassembled to avoid damage to the pump due to poor lubrication of bearing lubrication due to solidification and cracking of the melt.
