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 zone —— 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 Industry Forum) 2017: “My Technical Upgrades” in the coal chemical industry. http://bbs.hcbbs.com/thread-1786290-1-1.html (Source: Haichuan Chemical Industry 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 Industry Forum website)

The pump shaft and the motor shaft are not aligned, resulting in high load on the motor; there is too much or too little oil in the tank; the motor is missing one phase; the lubricating oil has deteriorated; the motor overheats; the bearings are not properly fitted
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.
1) The pump shaft and the motor shaft are not aligned. 2) The motor is under excessive load. 3) There is too much or too little oil in the tank. 4) The motor is operating with one phase missing. 5) The lubricating oil has deteriorated. 6) The motor itself generates heat. 7) The bearings are not properly installed
1. The pump shaft and the motor shaft are not aligned. 2. The motor is under high 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. The lubricating oil has deteriorated. 6. The motor generates heat on its own. 7. The bearing is not properly assembled.
The bearing friction is too high, resulting in excessive motor current.
