Description

Primary frequency modulation power correction device Technical Field The utility model relates to the technical field of frequency modulation power correction, in particular to a primary frequency modulation power correction device. Background The primary frequency modulation power correction is a key technology for guaranteeing the stable operation of the power system. When the power grid frequency deviates from the rated value, the power generator set can automatically adjust the active power through primary frequency modulation, so that frequency fluctuation is quickly restrained, and when the frequency modulation is corrected, the flow and the flow velocity of fuel can be controlled by adjusting the rotating speed of the impeller and the opening and closing degree of the valve. The existing correction device has the defects in fuel oil filtration and multiple adjustment modes, and the practicability is required to be improved. Disclosure of utility model The utility model aims to provide the primary frequency modulation power correction device which can effectively filter fuel oil, can flexibly and conveniently replace a filter structure, can perform various adjustment operations and has strong practicability. In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a primary frequency modulation power correction device, includes the jar body, fixedly connected with two second feed liquor pipes on the surface of one side of the jar body, the one end of second feed liquor pipe is provided with the third feed liquor pipe, the one end intercommunication of third feed liquor pipe has two first feed liquor pipes, the one end outside slip of first feed liquor pipe has cup jointed movable tube seat, movable tube seat's internally mounted has the oil filter core, the other end screw thread cup joints in the one end outside of second feed liquor pipe, a control valve is all installed in the pipeline of first feed liquor pipe and second feed liquor pipe. Through adopting above-mentioned technical scheme, can carry out the filtration operation to the fuel, filtration back at a period of time simultaneously can be convenient change the operation to the oil filter core. Further, a liquid return pipe is fixedly connected to the upper surface of the tank body, and a first flow regulating valve is arranged in a pipeline of the liquid return pipe. By adopting the technical scheme, the opening and closing of the liquid return pipe can be controlled by the first flow regulating valve, and the fuel oil supply quantity can be regulated by brief introduction.
