What are the reasons for overheating of the pump’s bearings and motor? Answer: 1) The pump shaft and the motor shaft are not aligned. 2) High motor load. 3) There is too much or too little oil in the tank. 4) The motor will not operate if one phase is missing. 5) Degraded lubricating oil. 6) The motor generates heat on its own. 7) The bearing is not properly assembled. http://down.hcbbs.cc/attachment/forum/201706/10/203353z7y06fdo70r6eod0.jpg Petrochemical area —— New ideas for energy savings: the “Creative Ideas” campaign (the second phase is in full swing). http://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1666758 (Source: Haichuan Chemical Forum) 2017: “My Technical Upgrades” in the coal chemical industry. http://bbs.hcbbs.com/thread-1786290-1-1.html (Source: Haichuan Chemical Forum Website) First round of voting for the best e-books on Haichuan Forum —— Chance to win prizes by voting (for members of the Management and Technology Group and those in grade 5 or above). http://bbs.hcbbs.com/thread-1799455-1-1.html (Source: Haichuan Chemical Forum Website)

Axis misalignment, overly tight bearings, excessive outlet pressure, high flow rate, lack of oil in the bearing housing, lubricant emulsification

Pay attention to the following points: ① The cooling water for each section cannot be stopped immediately; it must wait until the temperature of each section drops to normal levels before the water supply can be halted. ②Close the inlet valve and preheating valve tightly. ③Rotate the pump every 15–30 minutes while cooling it down, until the temperature of the pump body drops below 100°C.
