The invention discloses a self-circulation full-automatic hub pressure maintaining oil system of a large bulb tubular turbine unit. The system is composed of the bulb tubular turbine unit, an oil head, an oil collecting device, an oil return tank, a high-pressure oil tank, a speed regulator, a hub top oil tank, an oil supplementing valve, an oil head leak oil pipe, high-pressure oil pipes, an oiloverflow pipe, a hub top oil tank manual oil draining valve, hub pressure maintaining oil pipes and a leak oil pump. The whole bulb tubular turbine unit is arranged in a flow channel. The oil head andthe oil head leak oil pipe are located in a bulb head of the bulb tubular turbine unit. The oil collecting device is located in a gallery located on the lower portion of a runner chamber of the bulbtubular turbine unit. The oil supplementing valve, the high-pressure oil tank, the speed regulator and the oil return tank are located at the 58m elevation of a main power house. The hub top oil tankand the hub top oil tank manual oil draining valve are located at the 65.15m elevation of the main power house, and the high-pressure oil pipes and the hub pressure maintaining oil pipes are distributed in the whole plant. According to the self-circulation full-automatic hub pressure maintaining oil system of the large bulb tubular turbine unit, full-automatic circulation of hub pressure maintaining oil can be achieved, the operation and maintenance workload can be effectively reduced, the safe operation reliability of the unit is improved, and the utilization rate of auxiliary power is decreased.
Description
technical field [0001] The invention relates to a self-circulating full-automatic hub pressure-maintaining oil system for a large-scale bulb tubular unit, which belongs to the technical field of hydroelectric power generation. Background technique [0002] The bulb tubular unit is generally equipped with a high-level oil tank in the hub to provide pressure-maintaining oil with a certain pressure in the hub body. At present, the hub pressure oil system commonly used in the bulb tubular unit is to replenish oil from the high-pressure oil tank of the governor to the high-level fuel tank of the hub (there is no special requirement for the oil level of the high-level fuel tank of the hub, as long as there is always oil in the tank), the high-level fuel tank of the hub The oil tank supplies oil to the oil receiver, the oil receiver leaks oil to the oil collection device, and then the oil collection device pumps oil to the oil tank, and the turbine oil in the oil tank is pressurize...
