What is the purpose of condensate extraction pump?
What is the purpose of condensate extraction pump?
Condensate extraction pumps (CEP) extract the condensate water from the condenser and pump it through the condensate polishing system and the LP heaters to the de-aerator feed water tank.
What will happen if the first resistance is created by the pump volute when catches the liquid?
Creating a resistance to the flow controls the kinetic energy of a liquid coming out of an impeller. The first resistance is created by the pump volute (casing), which catches the liquid and slows it down.
Why is suction pressure negative in CEP?
Why is there negative pressure in the condenser of a power plant? Negative pressure or vacuum is created in a condenser so that steam can easily flow into the condenser and more work output is obtained from the turbine.
What is ACC in power plant?
An air cooled condenser (ACC) is a direct dry cooling system where steam is condensed inside air-cooled finned tubes. The cool ambient air flow outside the finned tubes is what removes heat and defines the functionality of an ACC.
What happens if condensate pump fails?
What Happens If a Condensate Pump Fails? The biggest indicator of an issue with your condensate pump is that your air conditioner won’t turn on. The AC shuts off to prevent the pump’s water reservoir from overflowing. If your condensate pump is malfunctioning, it may need to be repaired, cleaned or replaced.
Why pump suction is greater than discharge?
Suction pressure diameter is usually 1 size higher than discharge, because we need minimum resistance in the suction side to reduce the losses and increase the NPSHa.
What is the use of bypass line in the discharge line?
Re: Purpose of bypass in discharge lines A small (1″ in this case) “Warm-up” bypass in installed around the check valve to allow the discharge pressure from the “Run” pump to back flow around the check valve of the stand-by pump and keep the pump warm.
What is the principle of pump?
A Pump is generally used to induce flow or raise the pressure of a liquid. Centrifugal pumps are a category of Dynamic pumps. The working principle of centrifugal pumps involves imparting energy to the liquid by means of a centrifugal force developed by the rotation of an impeller that has several blades or vanes.
How do pumps increase pressure?
Centrifugal pumps increase the pressure of the liquid by using rotating blades to increase the velocity of a liquid and then reduce the velocity of the liquid in the volute.
