Background
The conventional vacuum-pumping system of the thermal power plant is generally provided with two vacuum pumps with larger power, which vacuumize a condenser and pipeline systems connected with the condenser when a unit is started, and keep the operation state of the vacuum pumps to maintain the vacuum of the condenser until the generator unit is put into stable operation, and stop the operation after the generator unit is completely stopped. Conventional vacuum pumps function in two ways: firstly, establishing vacuum at the initial starting stage of the unit; secondly, in the normal operation of the unit, noncondensable gas leaking into the vacuum system is continuously pumped out of the vacuum system so as to maintain the high vacuum state of the system.

The system of the utility model mainly comprises a high-efficiency vacuum pump and a relevant pipe valve, and is connected with a conventional vacuum pumping system in parallel, thereby achieving the purpose of energy conservation.
The original vacuum system adopts two single-stage flat disk type vacuum pumps with larger power, and the functions are as follows: 1. and 2, establishing condenser vacuum at the initial startup of the condenser, and continuously pumping uncondensed gas in the condenser out of a vacuum system to maintain the high vacuum state of the condenser when the unit normally operates. The single-stage flat disk type vacuum pump is designed according to the maximum air extraction load, so that the power is higher, the power consumption is larger, but in the actual production operation, when a turbine unit normally operates, the air quantity leaking into a condenser is far smaller than the rated air extraction quantity of the vacuum pump, the smaller load is smaller, but the vacuum pump with high power is used, and the great electric energy waste is caused.
