Abstract

Abstract:

In order to improve the automation and information level of gas pumping stations in coal mines and reduce the energy consumption of gas pumping stations, the intelligent control method of gas pumping stations was put forward. Based on the objective analysis of the causes of high energy consumption of gas pumping stations, the intelligent pumping system of gas pumping stations was put forward. The method of intelligent transformation of the pumping system of gas pumping stations was adopted. By adding a frequency converter control motor to the water ring vacuum pump, the energy consumption of gas pumping and power generation data of gas power plants were further analyzed. The results show that the intelligent gas pumping station can reduce the energy consumption of gas extraction by more than 50% under the condition of safe production. The work intensity of the labor force was reduced by 80%.

Key words: gas pumping, pumping station, intelligentization, energy consumption, power generation
