Non-hydraulic numerical control fine-adjustment liquid viscosity speed regulator for high-precision wind power front end speed regulating synchronous power generation

Abstract

The invention provides a non-hydraulic numerical control fine-adjustment liquid viscosity speed regulator for high-precision wind power front end speed regulation synchronous power generation. The non-hydraulic numerical control fine-adjustment liquid viscosity speed regulator for the high-precision wind power front end speed regulation synchronous power generation is mainly composed of a machinebody, an input shaft, an output shaft, a friction plate assembly and an oil film control device. The friction plate assembly is arranged in a friction plate shell connected with the input shaft, the oil film control device is composed of a numerical control servo worm gear worm transmission device and a precision screw rod transmission device, and a screw rod drives a compression disk, a column pin and a pressing disk to move to adjust gaps between friction plates. According to the non-hydraulic numerical control fine-adjustment liquid viscosity speed regulator for the high-precision wind power front end speed regulation synchronous power generation, a traditional hydraulic system which regulates and controls the gaps of friction plates by hydraulic pressure in a liquid viscosity speed regulating clutch is fundamentally eliminated, non-hydraulic servo precision numerical control transmission is adopted to control the gaps of the friction plates, and the control accuracy can reach 0.01mm. The volume is small, the structure is simple, the operation is stable, maintenance is easy, the fine-adjustment ability is high, the application range is wide, and the service life is long; and nohydraulic station or fuel tank is required, and the steady speed and following requirements of wind power front-end speed regulating synchronous power generation can be met.

Description

technical field [0001] The invention relates to wind power front-end speed-regulating synchronous power generation equipment, in particular to a high-precision wind power front-end speed-regulating synchronous power generation without hydraulic numerical control fine-tuning liquid-viscosity governor. Background technique [0002] Wind power generation is an inexhaustible green and clean energy, and all countries in the world are researching and developing wind power generation technology. [0003] At present, the most commonly used wind turbines in the world are asynchronous wind turbines with variable speed and constant frequency. Although it can convert wind power into electricity, compared with the power quality of conventional power generation methods - thermal power, hydropower and nuclear power, the power quality is poor and the reliability is poor. There is a great potential danger to the connected grid. It is an unconventional power generation method. [0004] my ...

AI Technical Summary

Problems solved by technology

The conventional fluid-viscous speed-regulating clutch has poor adjustment performance, poor fine-tuning ability, and poor following performance, which cannot meet the requirements of wind power stability. Position, that is, to adjust the oil film thickness h of the friction plate group, the performance is greatly improved

However, it still does not deviate from the conventional hydraulic-viscous clutch mode of controlling the piston with hydraulic pressure to adjust the oil film thickness h of the friction disc group
