The invention belongs to the field of pumped storage equipment, and relates to pumped storage unit shafting vibration acquisition equipment which comprises an annular base arranged on the ground, the base is arranged at the lower end of a rotor spindle in a sleeving mode, the base and the rotor spindle are coaxially arranged, and multiple sets of marking devices are symmetrically arranged on the outer side wall of the lower end of the rotor spindle in the radial direction. Each marking device comprises a supporting rod and a flexible ball, one end of the supporting rod is fixedly connected to the side wall of the rotor main shaft, and the flexible ball is embedded in the other end of the supporting rod and rotationally connected to the supporting rod; an ink dripping device is arranged on one side of the flexible ball on the side wall of the rotor main shaft; the inner side wall of the base is detachably connected with an abutting plate, when the rotor main shaft does not rotate, and the flexible ball makes point contact with the abutting plate. The effect that the vibration amplitude of the shafting of the unit can be conveniently collected is achieved.
Description
technical field [0001] The present application relates to the field of pumped energy storage equipment, in particular to a shafting vibration collection equipment of a pumped energy storage unit. Background technique [0002] The pumped storage power station is a hydropower station that pumps water from the power system's low-peak electricity and generates electricity during the peak load. The pumped storage power station has two reservoirs, the upper and the lower, and uses the remaining power when the power system is in low demand to pump water from the lower reservoir to the upper reservoir to store energy; The reservoir releases water to generate electricity. [0003] The rotor of the hydraulic turbine is prone to shafting vibration, which mainly includes bending vibration, axial vibration and torsional vibration, which are caused by periodic excitation such as burst pressure and inertial force during work. Their mutual coupling makes the crankshaft work under alternat...
