Measures to improve the running life of high temperature gear pump 1, due to high temperature gear pump body running at high temperatures, so cold installation pipe should be set hinge support seat to prevent pipe displacement after warming. 2, high temperature gear pump outlet melt filter to be replaced on a regular basis, do not long-term high pressure and pressure in the upper limit of operation. 3, the coupling must heat the heat after the pump to find the correct, in order to avoid running additional torque. 4, high temperature gear pump outlet pressure measuring point to be set to stop interlocking alarm, otherwise, once the discharge pipe is blocked, easy to cause damage to the pump. 5, the speed to be slow, do not make the sharp rise in pressure before and after, so as not to damage the bearings or melt blocked the lubrication channel. 6, the pump starts, no pressure in the export formation, can not be blindly speed, to prevent premature failure of the shaft or bearing. 7, 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. 8, cleaning pipetting, do not pump delivery of cleaning fluid, the inner parts should be removed, pipetting after the end of installation, so as not to pump foreign matter. 9, in case of power outage or heat medium cycle interrupt more than 3Omin, the pump should be disassembled after cleaning reassembly, so as to avoid melt curing, cracking and other caused by poor bearing lubrication and high temperature gear pump damage.
