Regarding the rapid shutdown components and starting oil of steam turbines

Search on Baidu; there’s a lot of content on this topic

Is it from Hangzhou Motor? You can study the instructions; it’s actually quite easy

The landlord needs to upload the PID diagram of the oil circuit so that everyone can study it.

The assembly is called a quick-shut assembly device, which is primarily used to control the quick-shut valve and regulate the steam valve. There are three pipes connected to the throttle valve for adjusting the flow of oil: one is the secondary oil coming from the rapid shutdown assembly, which is used to control the degree to which the throttle valve opens; the second is the high-pressure oil coming from the high-pressure oil main line; and the third is the return oil for the throttle valve. (Detailed information on throttle errors can be found in other posts.) The quick-shut valve (also known as the main steam valve) is equipped with four pipes: one of these carries the starting oil from the quick-shut assembly, which is used to apply preload to the spring inside the quick-shut valve ； The second circuit is the quick-shut oil from the quick-shut assembly, which is used to open and close the quick-shut valve ； The third stream is the test oil from the quick-shut combination device, which is used to check online whether the quick-shut valve is stuck ； The fourth path is the quick-close valve return oil ； In addition to the above, the quick-shut combination device also has three oil circuits. It is the quick-shut oil coming from the emergency cut-off throttle mounted on the front bearing housing ； The second path is the oil supply from the quick-shut combination device connected to the high-pressure oil main pipe ； The third path is the return oil for the quick-shut combination device ；
