【Q&A Question 138】September 5, 2016: What are the consequences of a disruption in the cooling water supply for hot oil pumps? The answer key will be available after responding; scoring is based on answering the key points. If the cooling water supply is interrupted, it becomes impossible to control the temperature rise of the pump; this can lead to a rapid increase in the temperature of the bearing housing in a short period of time. The seals heat up, causing oil to leak from the pump. Over time, this can result in heating of the pump itself, leading to damage. The lubricating oil oxidizes and deteriorates, and in severe cases, it can cause the shaft to seize, trigger a shutdown, and cause serious damage to the components inside the pump.
The pump body temperature continues to rise, the shaft temperature increases, sealing leaks occur, and in severe cases, shaft seizure can happen
It is not possible to control the temperature rise of the pump; in a short period of time, this can lead to a rapid increase in the temperature of the bearing oil tank. The seals may overheat, causing the pump to leak oil. Over time, the bearings can overheat and get damaged, the lubricating oil can oxidize and deteriorate, the oil tank can become extremely hot, and this may even result in the shaft seizing or the pump tripping.
Once the cooling water supply is interrupted, it becomes impossible to control the temperature rise of the pump. In a short period of time, this can lead to a rapid increase in the temperature of the bearing oil tank; the seals will heat up, causing the pump to leak oil. Over time, the bearings will overheat and get damaged, the lubricating oil will oxidize and deteriorate, the oil tanks will become hot to the touch, and this can even result in the shaft seizing or the pump tripping, thereby causing severe damage to the internal components of the pump.
In a short period of time, this can cause the temperature of the bearing oil tank to rise rapidly; heat generated due to sealing issues can lead to oil leakage from the pump. Over time, it can cause the bearings to overheat and get damaged, as well as cause the lubricating oil to oxidize and degrade, resulting in bearing seizure, tripping, and severe damage to the internal components of the pump
Answer: Once the cooling water supply is interrupted, it becomes impossible to control the temperature rise of the pump. In a short period of time, this can cause the temperature of the bearing housing to rise rapidly; the seals will heat up, leading to oil leakage from the pump. Over time, the bearings will overheat and get damaged, the lubricating oil will oxidize and deteriorate, the oil tank will become hot to the touch, and this can even result in the shaft seizing or the pump tripping, causing severe damage to the components inside the pump.

Seal leakage, burned bearings, damaged pump
Seals, bearings, etc., suffer from excessive heating, which accelerates wear and can lead to leaks of the medium and lubricating oil
Once the cooling water supply is interrupted, it becomes impossible to control the temperature rise of the pump. In a short period of time, this can lead to a rapid increase in the temperature of the bearing oil tank; the seals will heat up, causing the pump to leak oil. Over time, the bearings will overheat and get damaged, the lubricating oil will oxidize and deteriorate, the oil tank will become hot to the touch, and this can even result in the shaft seizing or the pump tripping, thereby causing severe damage to the internal components of the pump.
Harm: In a short period of time, it can cause the temperature of the bearing housing to rise rapidly; the seal heats up, leading to oil leakage from the pump. Over time, this can result in overheating of the pump, oxidation and deterioration of the lubricating oil, and even shaft seizure, tripping, and severe damage to the components inside the pump.
