Abstract

The invention relates to the field of hydroelectric generation equipment, and discloses a hydraulic vertical mixed-flow generator set. The hydraulic vertical mixed-flow generator set comprises a waterturbine shell and a generator set body, a draft tube is arranged at the bottom of the water turbine shell, a volute is arranged in the middle of the water turbine shell, a rotating wheel is movably sleeved with the middle of an inner cavity of the water turbine shell, guide vanes are arranged between the volute and the rotating wheel, the top of the rotating wheel is fixedly connected with a linkage guide shaft, and the top end of the linkage guide shaft extends into the generator set body. According to the hydraulic vertical mixed-flow generator set, through the structural design of an air inlet pipe, a first guide pipe, a second piston, a push shaft and a second guide pipe inside an air supplementing pipe machine at the top end of the linkage guide shaft, when high-strength positive airnegative pressure occurs in the draft tube, air directly enters the air inlet pipe through an air guide hole in the top of the air supplementing pipe, the air sequentially flows through a positioningcoil and the linkage guide shaft to enter the draft tube to supplement air to the draft tube, so that the vacuum degree in the draft tube is reduced, the running state of a unit is improved, and theservice life of the mixed-flow generator set is prolonged.

Description

technical field [0001] The invention relates to the field of hydroelectric power generation equipment, in particular to a hydraulic vertical mixed-flow generator set. Background technique [0002] Mixed-flow generators include vertical and bedroom mixed-flow generators. The two generators are often used in hydropower generation in different environments. Among them, the vertical mixed-flow generator set is mainly composed of a generator set and a water turbine set, and flows into the water turbine tangentially through the water flow. , acts on the water wheel in the water turbine to make it rotate, thereby driving the common shaft between the water turbine and the generator set to rotate, and the rotating mechanical energy is converted into electrical energy in the generator set to generate electricity. [0003] During the use of the existing vertical mixed-flow generator, due to the destruction of the spiral vortex caused by the tangential component of the water flow at the...
