Introduction to cooling methods for heavy oil pumps

Cooling of heavy oil pump: A cooling water jacket is installed around the sealing chamber of the heavy oil pump, which is cooled with cold water to reduce the temperature of the sealing chamber to 200-250 ℃; For single end sealing, injection flushing is used to introduce clean wax oil with a temperature of around 100 ℃ from the outside (usually diesel is not used because diesel is a finished product), which not only reduces the temperature but also improves the working environment. This is a feasible method. The specific method is as follows:
