Abstract

The invention discloses a power multi-branch hydraulic planetary speed regulating device, and relates to the technical field of speed regulating devices. The power multi-branch hydraulic planetary speed regulating device mainly consists of a gear power dividing system, a hydraulic torque converter system, a planetary gear system, a lubricating oil system and the like, wherein the hydraulic torque converter system adopts a guide vane adjustable type hydraulic torque converter, and consists of a pump wheel, a turbine, a fixed guide wheel, an adjustable guide wheel, a performing mechanism and the like; and the planetary gear system is a differential wheel system, and consists of an inner gear ring, a planetary frame, a planetary wheel and a solar wheel. The novel stepless-speed transmission device operates according to the power dividing principle. The power multi-branch hydraulic planetary speed regulating device is relatively high in efficiency of the whole machine and has a rated working condition which can be about 95% as efficiency of the hydraulic torque converter is not high, and dividing power of the hydraulic torque converter is relatively small.

Description

Technical field: [0001] The invention relates to the technical field of speed regulating devices, in particular to a power multi-branch hydraulic planetary speed regulating device. Background technique: [0002] Improving energy utilization efficiency is an important direction for the development of scientific and technological equipment at present. my country's power plant equipment has developed rapidly in the direction of large-capacity, supercritical or ultra-super unit. When the thermal power plant is running, after the water in the boiler is heated and turned into steam, the water supply pump supplies water to the boiler and maintains the normal water level. Boiler feed water pump is an important auxiliary equipment of thermal power plant. The thermal power plant adjusts the peak several times a day, and the steam temperature and steam pressure change with the change of the unit load. It is necessary to adjust the working conditions of the boiler feed pump in time acc...
