In KWU 500MW unit, If any of Running TDBFP hand tripped form DCS pannel, MDBFP will START in Auto Or not? (MDBFP is in standby mode)

[@qolisfandrairawan2130]

Sir, why the pump speed is higher than motor speed ? By using hydraulic coupling, the output speed must lower than motor speed, isn't ?

[@kpatelbla]

Actually Motor input power must be higher than pump output, but RPM can be increased by hydraulic coupling, no issue. Suppose Motor input power 12 MWH so pump mechanical output cannot exceed 12 MWH.

Dear sir please make on governing system full process and how governer work like giving 600 MW to 500 mw etc

[@kpatelbla]

It is very interesting topic, I will make it in simplest way of explanation.

@@kpatelbla thanks 🙏🙏 you sir waiting for the video

Sir Before starting of MDBFP reheater Attempretion valve and super heater Attempretion valve always should have open or not...?

[@kpatelbla]

It can be made open but block valve of both attemperator must be closed.

[@user-wm5ti1od6r]

Good explanation. Please explain Operation of hydraulic coupling. Scoop function and Remote trip solenoid

[@kpatelbla]

You can watch ' How scoop tube function' video kzbin.info/www/bejne/jXqvoqqnmrGXb6csi=C8mw2HscAzPMFJdq

Remote trip solenoid & Rapid start, I will explain.........

Sir boostor pump suction me buket stainer or main pump me conical stainer hota hai or sir boostor pump ka suction pr 8 kg tak hota hai

[@kpatelbla]

Yes you are correct, but suction pressure varies according to Deaerator pr

[@chandreshpatel6380]

Sir need video on bearing stiffness or shaft stiffness

[@kpatelbla]

Ok

[@devivara1162]

Sir what is water hammer??? any 3 reasons why this water hammer forms??

[@kpatelbla]

When steam comes in contact of condensate water it moves with high velocity of steam and create hammering sound on pipe surface, before it get condense.

[@motive0507]

ECW water is going to mechanical seal cooling and also to seal jacket. What is seal jacket. Please differentiate mechanical seal and seal jacket

[@kpatelbla]

Mechanical seal water goes to mechanical seal cooler instead of directly to mechanical seal. Jacket cooling provided at pump jacket.

[@motive0507]

@@kpatelbla could you please physically differentiate seal jacket and mechanical seal

[@motive0507]

Please give reply

[@devivara1162]

Sir why balancing line is provided before pump in Condensate extraction pump??in power plant???

[@kpatelbla]

The only purpose of balancing line is to prevent the shifting of Rotor of the pump during operation.
