The condensate issue with the turbine exhaust pump.....

Moving the condensate to the inlet pipeline of the condensate pump is not feasible

Why? Afraid of the pump inflating? There is also a certain degree of vacuum at the source...

It’s better to go into the condensate tank; after all, this provides a buffer. Additionally, the generation of condensate is related to the quality of the steam. If it goes directly into the pump inlet, there’s no guarantee that no steam will enter the pump as well, which could lead to cavitation~~

The key issue is that the condensate cannot return to the condensate tank; the pipes have been checked and are fine...

If the exhaust pump is a water ring vacuum pump, the vapor-water mixture at the outlet of this pump is sent to a gas-water separator. The working water that results from this separation – which includes some steam condensate – is cooled in a water-to-water heat exchanger before being returned to the inlet of the water ring vacuum pump, where it can be used again as the working fluid for the pump. Therefore, introducing this fluid into the inlet of the condenser not only fails to meet the process requirements but also undermines the vacuum level in the condenser; hence, it is definitely not acceptable. If the extractor is a steam ejector, it is usually a two-stage extractor; the condensed water at its outlet is discharged into the condensate recovery tank, namely the condenser, via a trap. The reason why the condensate cannot return to the condenser may be an excessive pressure inside the tank or a malfunction in the trap. The secondary drain water from the extractor can be poured into the condenser for reuse, but it must pass through a drain valve; if it is connected directly to the condenser without such a valve, the high vacuum inside the condenser will make it impossible to control the water level. As a result, not only does condensed water enter the condenser, but also the non-condensable gases from the secondary stage of the extractor enter as well, and in some cases air may even be drawn in from the exhaust pipe, thereby affecting the vacuum level of the condenser. To check this, one can simply turn off the secondary drain valve and open the drain gate to observe how the drain water flows.

What was said upstairs is very clear; the original poster should go back and check it accordingly

It’s better to send it to the condensate tank, as this provides a buffer. Additionally, the formation of condensate is related to the quality of the steam; if it enters the pump’s inlet directly, there’s no guarantee that no steam will get into the pump, which could cause problems

Thank you very much for your analysis. We are using a steam ejector; there is no problem with the discharge of condensed water at the second stage. We also suspect that there might be an issue with the steam trap, so we will have to wait for an opportunity to check it.......

What I want to say is that we also use steam ejectors, but we don’t have a drain valve after the cooler; instead, we connect pipes directly from the cooler to the condensate tank. What are the consequences of having no strainer?
