| description | The invention relates to a method and a device for improving the circulating heat efficiency of a generator set, aims at overcoming the defect that the circulating heat efficiency of a generator set of an existing thermal power plant is difficult to increase, and provides a method for improving the circulating heat efficiency of a thermal power plant generator set and a vacuum pump system. The method for improving the circulating heat efficiency of the thermal power plant generator set is characterized by comprising the following steps that the spring constant of a torsion spring of a double-clack check valve of the vacuum pump system is reduced, when the double-clack check valve is completely opened, the torsion F of the torsion spring is 1.05-1.1 times of the closing resistance f of thedouble-clack check valve, so that the side pressure P2 of a condenser is further close to the side pressure P1 of a vacuum pump. By adopting the mode, the torsion F of the torsion spring of the double-clack check valve can be |
