Embodiment Construction
[0031] The present invention is an emergency oil replenishment device and method for a pressure vessel of a hydraulic system of a turbine governor, which can automatically control the emergency oil replenishment according to the liquid level and pressure of the pressure oil tank in an emergency state where oil is lacking and needs to be replenished due to oil leakage in the system. The device performs automatic oil replenishment to ensure that the oil-gas ratio in the pressure oil tank of the hydraulic control system of the turbine governor is within a reasonable range, thereby ensuring that the hydraulic control system of the governor can provide a long-term and stable pressure oil source that meets the pressure index to operate the guide vane opening. degree implementing agency.
[0032] The structure diagram of the emergency oil replenishment device for the pressure vessel of the hydraulic system of the turbine governor is as follows figure 1 As shown, it includes: fuel sup...

An emergency oil replenishment device and method for a pressure vessel of a hydraulic system of a water turbine governor, comprising an oil replenishment tank and an oil tank. In the emergency state of oil shortage caused by oil leakage in the system and need to be replenished, it can automatically control the emergency oil replenishment device to automatically replenish oil according to the liquid level and pressure of the pressure oil tank, so as to ensure the oil and gas in the pressure oil tank of the hydraulic control system of the turbine governor. The ratio is within a reasonable range, thereby ensuring that the governor hydraulic control system can provide a long-term and stable pressure oil source that meets the pressure index to operate the guide vane opening actuator.
Description
technical field [0001] The invention belongs to the technical field of the hydraulic control system of the governor of a hydro-generator set, and in particular relates to an emergency oil replenishing device and method for a pressure vessel of a hydraulic system of a hydro-turbine governor. Background technique [0002] The governor of the hydro-generator set adjusts the opening of the guide vane, the power and the frequency of the unit, and the hydraulic control system of the governor needs to provide a long-term and stable pressure oil source that meets the standards in terms of pressure, temperature, and pressure oil particle content to operate the guide. Leaf opening actuator. Because the oil is not easily compressible, in order to ensure that the oil has a relatively stable pressure, part of the gas must be filled in the pressure vessel, and the hydraulic control system of the governor needs to control the automatic air supply system according to the content of the gas ...
