Embodiment Construction

[0031] The invention discloses an emergency oil replenishment device and method for a pressure vessel of a hydraulic system of a water turbine governor, which can automatically control emergency oil replenishment according to the liquid level and pressure of the pressure oil tank in an emergency state where oil leakage in the system causes oil shortage and oil replenishment is required. The device automatically replenishes oil 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, so as to ensure that the hydraulic control system of the governor can provide a long-term stable pressure oil source with a pressure index up to the standard to operate the guide vane opening Executing agency.

[0032] The structural diagram of the emergency oil replenishment device for the pressure vessel of the hydraulic system of the hydraulic turbine governor is shown in figure 1 As shown, it includes: oil re...

Abstract

The invention provides an emergency oil supplementing device and method for a pressure vessel of a hydraulic system of a hydraulic turbine governor. The device comprises an oil recharging tank and an oil tank, the oil recharging tank is connected with the oil tank through an oil pipe, and an oil recharging electromagnetic valve is arranged on the oil pipe. In an emergency state of oil shortage and oil supplementation due to oil leakage of the system, the emergency oil supplementing device can be automatically controlled to carry out automatic oil supplementation according to the liquid level and the pressure of a pressure oil tank, so that the oil-gas ratio in the pressure oil tank of a hydraulic control system of the hydraulic turbine governor is in a reasonable range, therefore, the hydraulic control system of the governor can provide a long-acting and stable pressure oil source with the pressure index reaching the standard to operate a guide vane opening executing mechanism.

Description

technical field [0001] The invention belongs to the technical field of a hydraulic control system for a governor of a hydroturbine generator set, and in particular relates to an emergency oil supply device and method for a pressure vessel of a hydraulic system of a governor of a hydroturbine generator. Background technique [0002] The governor of the hydro-generator set adjusts the opening of the guide vane, unit power and frequency, and the hydraulic control system of the governor needs to provide a long-term 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. Due to the incompressibility of the oil, in order to ensure that the oil has a relatively stable pressure, some gas must be filled in the pressure vessel, and the hydraulic control system of the governor is required to control the automatic air supply system according to the gas content in the pressure ve...
