Abstract

The invention discloses a cooling water supply system of a bulb tubular turbine generator set. The cooling water supply system comprises a unit flow channel, a bulb, two or more groups of cooling water supply subsystems, a draw water chamber and a bearing oil cooler, wherein each cooling water supply subsystem comprises a water sucking main pipe, a water supply pump, a water outlet main pipe, an automatic water filter, a generator air cooler group, pipelines and a valve; the water supply pump is arranged in the bulb or on a flow channel cover plate, and the automatic water filter is arranged in the lamp bulb or on the flow channel cover plate; the water supply pump takes water from the draw water chamber through the water sucking main pipe and the valve, and is connected with the automatic water filter through the water outlet main pipe and the valve and then respectively connected to the generator air cooler group and the bearing oil cooler; an exhaust port of the generator air cooler group and an exhaust port of the bearing oil cooler are respectively communicated with the unit flow channel through the pipelines. The cooling water supply system provided by the invention has the characteristics of no restriction in cooling capacity, good cooling effect, good reliability and stability, easiness in manufacture, convenience in maintenance and low cost, and has application value of market promotion.

Description

technical field [0001] The invention relates to the technology of a hydroelectric generating set, in particular to a cooling water supply system of a bulb tubular type hydroelectric generating set. Background technique [0002] The cooling methods of large and medium-sized bulb tubular hydroelectric generators operating in the prior art can be summarized into the following two or two types: [0003] The first type: the secondary cycle cooling method of "air cooler-water cooler". [0004] The air cooler is located in the air circulation process of the generator cabin, which is similar to the air cooler arrangement of a common vertical unit. The "water cooler" of the bulb tubular hydroelectric generator set generally has two arrangements according to the capacity of the unit: one is in the form of a cooling jacket, that is, a section of the outer shell of the bulb body is made into a hollow interlayer, and The side in contact with the river water is made of stainless steel c...
