What is the effect of the liquid level in the compressor’s secondary extraction cooler on the vacuum level and the exhaust temperature? I think the high liquid level, combined with poor pumping performance by the secondary pump, results in inadequate vacuum creation by the primary pump; this in turn leads to an increase in vacuum level and an increase in exhaust temperature ； The liquid level is low; the secondary extractor is connected to the condenser, which results in an increased vacuum level and a higher exhaust temperature ； I’m not sure if it’s correct; I’d appreciate everyone’s advice
1) When the water level in the steam side space of the condenser rises, it submerges part of the copper tubes below, reducing the cooling area of the condenser and thereby increasing the exhaust pressure of the turbine, that is, decreasing the vacuum. (2) If the condenser water level rises to the height of the air extraction pipe opening, the condenser vacuum begins to drop. Depending on the extent to which the condensate water submerges the exhaust port, the vacuum level decreases slowly at first and then drops rapidly; at this point, the vacuum gauge connected to the throat of the condenser shows a decrease, while the vacuum gauge connected to the ejector shows an increase. If necessary measures are not taken in a timely manner, water will emerge from the exhaust pipe of the extractor.
