The hot well is a water collecting well for collecting condensed water at the lower part of the condenser. The device is called a condenser hot well and is commonly called a hot water well. An upright cylindrical member is mounted at the bottom of a surface condenser of a steam turbine. To collect the main condensed water generated by the continuous condensation of a large amount of dead steam. It is called a hot well because it looks like a water well. The accurate measurement of the water level of the condenser hot well is very important for the safe and economic operation of the unit, and the strict monitoring of the water level is more important because the operation parameters change greatly in the starting and stopping processes of the unit. The too high corrosion that can lead to the condensate oxygen content to increase and accelerate the condenser copper pipe when submerging the copper pipe of hot well water level to reduce the security and the reliability of equipment use, when the hot well water level risees to submerging the air pipe, can make the water jet air extractor draw water, condenser vacuum value seriously descends, if continue the area load under this kind of condition, can cause the unit to take place overload operation, the hot well water level is low excessively, will arouse condensate pump cavitation, direct influence condensate pump safe operation. However, the prior art cannot automatically adjust the water level according to the water level change of the hot well. In view of this, we propose a new kind of condenser hot well liquid level control device of condensing steam turbine.
