Therefore, it is an ideal goal pursued by each power plant to ensure that the generator set operates at the best vacuum as possible;
therefore, the vacuum pumping system is an indispensable device in the nuclear power unit, and the main functions of the vacuum pumping system are as follows:
(1) the method comprises the steps that condenser vacuum is established at the initial stage of starting a generator set, when a steam turbine enters steam and warms up, steam enters the condenser, and if the condenser does not establish certain vacuum, the steam enters the condenser to enable the condenser to form positive pressure and damage equipment;
(2) the condenser vacuum is kept in the operation process of the generator set, the safe and economic operation of the generator set is ensured, the condenser is in a vacuum state in the operation process, and air leaks into the condenser due to the fact that pipelines and a shell are not tight, so that the condenser vacuum is damaged, and the safe and economic operation of a steam turbine is not facilitated.
