Could everyone help explain this small turbine! ! !

Question 1: What type of turbine is this, as can be seen from the diagram? How to view it? Question 2: Could you explain the flow path of the steam? Why is a condenser added here? One path leads to the drain, and another returns to the condensate system; however, the valves are closed. Question 3: Figure 3 shows a quick-close valve – what is its working principle? Yamaku rapid shut-off valve Question 4: Please explain the flow path of the auxiliary oil pump, both during shutdown and during operation Thank you all! Figure 1 shows the overall view of the turbine; Figure 2 depicts the steam exiting through the condenser; Figure 3 is the quick-shut valve; Figures 4 and 5 show the auxiliary oil pumps! What I know is that the main steam is at high pressure, the back pressure is at medium pressure, and the rotational speed is around 1500 revolutions per minute.
Steam turbines are generally divided into back-pressure type and condensing type; this one is of the condensing type. Our site provides a detailed discussion on the differences between them, which you can find by searching for it. To find out the direction of the lubricating oil, you should consult the machine’s documentation and operating procedures.
What a cute turbine! This is a mini version of a condensing steam turbine; it’s just a smaller-sized machine, but its basic operating principle and layout are the same as those of a regular steam turbine!
Is it a condensing type because there are many steam traps? The condenser should be an oil cooler; is the quick shut-off valve an electromagnetic valve? Does the auxiliary oil pump pump oil to the oil cooler for heat exchange, and then to the main engine?
