Abstract

The invention discloses a method for reducing vibration of a high-pressure compressor and a vibration damper used in the method. The method comprises the following steps that a concrete base layer is manufactured, vibration damping units from the first to the sixth are installed on a reinforcement mesh; circular holes for threaded rod leveling are drilled in the four end corners of lower steel plate, and threaded holes are correspondingly machined in connecting steel plates according to the positions of the circular holes; threaded rods penetrate through the circular holes, the bottom ends of the threaded rods are in threaded connection with the connecting steel plates and are welded to the connecting steel plates, and each threaded rod is in threaded connection with a first regulating nut, a second regulating nut and a locking nut; vibration damping pads of all vibration damping units are placed on the reinforcement mesh together with the connecting steel plates, all the connecting steel plates are wielded to the reinforcement mesh, and all the six vibration damping pads are leveled; a concrete covering layer is manufactured; and bases of the high-pressure compressor are welded to the upper steel plates on the vibration damping pads. The invention further provides the vibration damper. By means of the method for reducing vibration of the high-pressure compressor and the vibration damper used in the method, vibrations of the high-pressure compressor are obviously reduced, the vibration numerical value of the vibrations of high-pressure compressor is substantially reduced, and it is guaranteed that the high-pressure compressor can normally operate in long time.

Description

technical field [0001] The invention relates to a method for strengthening and reducing vibration, in particular to a method for reducing the vibration of a high-pressure air machine. The invention also relates to a vibration damping device for reducing vibration of a high-pressure gas machine. Background technique [0002] Hebei Zhanghewan Pumped Storage Power Station is located in Jingxing County, Shijiazhuang City, Hebei Province. The total installed capacity of the power station is 1,000MW, and four 250,000kW single-stage mixed-flow reversible units are installed, which are connected to the southern Hebei power grid with a 500kV line. h. The power station consists of upper and lower reservoirs and underground powerhouses. The Upper Reservoir is located on the top of the mountain and is formed by excavation and filling. The normal storage level is 810m, and the total storage capacity is 7.854 million m 3 , with a storage capacity of 7.2 million m 3 , the whole librar...
