High-speed pump for lean amine solution
Thread Content
What is the purpose of the two tubes marked in red in Figure 1? What is the purpose of the tube marked in red in Figure 2?
Are there no installation diagrams for the equipment? In Figure 1, the thicker one is likely the exhaust, and the thinner one is the PLAN13 flushing tube. The two elements in Figure 2 are likely the inlet and outlet ports of the cooling water chamber, or leak detection ports for detecting seal leaks. Without cross-sections, it can only be a guess.
It can be seen that these are pumps from the 11th Aerospace Research Institute. In Figure 1, the thicker line represents the flow of material that flushes outside the pump chamber, while the thinner line likely indicates the flow reaching the pump inlet. In Figure 2, the opening at the bottom is probably the leakage point of the mechanical seal, while the one at the top is the leakage point of the oil seal. This is an interpretation based on lack of detailed drawings; confirmation must come from the actual drawings.
It is likely to be used for draining liquid after an (oil or water) leak
What does Figure 2 show regarding what is cooled by the cooling water? There are those with dedicated oil coolers; that’s option 13. The blind ones are used for exhaust
The blind dead end is used for exhaust; what’s shown in Figure 2 is just a guess. I outlined two possibilities: one involves a chamber filled with cooling water to reduce temperature, and the other is a leak detection port. Without cross-sections, one can only guess
As mentioned on the 3rd floor, it’s clearly a high-speed pump from the well-known Aerospace 11th Research Institute, haha. Figure 1: The one below should be the rinsing process, for PLAN13, right? The thick tube is the exhaust port. Figure 2 shows the leakage port. Find a diagram similar to that of a high-speed pump for reference.
