Why is the primary air inlet temperature so high after the reciprocating compressor shuts down due to an accident? Don't understand. . . .
My humble opinion: It may be that the inlet air valve is not closed tightly or is blocked by something, causing air leakage and air escaping.
The return valves at all levels are fully opened, and the high-temperature gas at the outlet returns to the first level step by step, so the temperature rises.
The compressed gas flows backward one level, so the temperature is high. The air valve of the reciprocating compressor is not tight in the static state, and can only be sealed instantaneously under dynamic conditions.
I completely agree with the point above. The compressor inlet and exhaust valves are not completely statically sealed. There is leakage in the static state, causing the high-temperature gas at the outlet to return to the inlet, causing the inlet temperature to increase.
But there is another problem. If the air valve is not tight, the intake and exhaust temperatures should be high! ! !
Personally think: The press should be in an unloading state when it is shut down. At this time, the suction valve should be in the top-open state. The rise in inlet temperature should be related to the exhaust valve not being closed tightly.
Makes sense! Combined with what the above friends said, it can basically be understood. But I just didn’t realize it in practice! How much can it increase? What is the exhaust temperature?
Reply 9# Be careful* * After a reciprocating compressor is shut down in an accident, it generally needs to be pressure relieved. The gas at the outlet of the high-pressure section is generally discharged to the inlet of the section, resulting in a high first-suction temperature.
