Background
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 operation parameter changes greatly in the starting and stopping processes of the unit, so that the accurate monitoring of the water level is more important. The influence of the overhigh and overlow water level of the condenser on the unit is mainly embodied in the following two aspects:
firstly, the method comprises the following steps: when the water level of the condenser is too high to submerge the copper pipe, the cooling area of the whole condenser is reduced, the vacuum value of the condenser is reduced, condensed water is supercooled, the condensed water can absorb air, the oxygen content of the condensed water is increased, the corrosion of the copper pipe of the condenser is accelerated, and therefore the use safety and reliability of equipment are reduced. Meanwhile, the temperature of the condensate water is reduced, and the steam extraction amount required by heating of the deaerator is increased, so that the heat efficiency of the unit is reduced.
Secondly, the method comprises the following steps: when the water level of the condenser rises to submerge the air pipe, the water jet air ejector can pump water, the vacuum value of the condenser is seriously reduced, if the water jet air ejector is continuously loaded under the condition, the unit can be caused to run in an overload mode, serious faults such as abrasion of a thrust bearing black gold, overlarge axial displacement or friction of a shaft seal and the like easily occur, if the vacuum value is reduced to 64kPa, low-vacuum protection can act, otherwise, a low-pressure cylinder steam exhaust valve can be exploded, and the unit is forced to stop running.
