One is added to each of the driving and non-driving ends of the centrifugal pump. The centrifugal pump is a hot oil pump with a medium temperature of diesel at about 280 degrees. What is this used for? What is its name? Please answer.
PLAN53B system, the left side is the heat exchanger, the big one on the right is the bladder accumulator, and the middle one with the handle is the manual rehydration pump
Well, there are famous brands on it. What is this system mainly used for? What are its advantages and disadvantages?
Prevent the process medium from leaking into the atmosphere, because the pressure of 53B is higher than the pressure of the sealing chamber during use. If the main seal is broken, the isolation liquid in the 53B system will enter the sealing chamber. When 53B leaks too much, the pressure will drop, and when it reaches a certain level, an alarm will be triggered (if any). At this point you know that the main seal is damaged and needs to be repaired.
Improve safety. If you only use a single-end type, 280-degree diesel will leak out and easily cause a fire.
It is a high-risk pump modification, which is a good thing for the safety of on-site operators.
