Description
Technical field
The utility model relates to a kind of oil circulation system, particularly relates to a kind of oil circulation system of hydraulic generator unit.
Background technique
Traditional hydraulic generator unit bearing oil external circulating system, employing all be that Lubricating-oil Station is set separately, be connected through oil pipe between Lubricating-oil Station and the unit bearing.Lubricating-oil Station is made up of elements such as oil pump, oil sump tank, oil cooler, valve, relays.Oil pump has two, a work oil pump, and an emergency bearing oil pump all needs power supply separately.
The working principle of Lubricating-oil Station is: oil pump is transported to the oil in the fuel tank in the hydraulic generator unit bearing under motor driving, so that cooling and lubricated bearing shell.Get back to the oil sump tank of Lubricating-oil Station by the road from the deep fat that bearing shell flows out, cool off the back by the cooler in the oil sump tank again and get into next work cycle.Cooler leans on the water supply of power station technology water system to carry out work, walks the heat of deep fat through the fluxion strap of water.
Such oil circulation system has following defective: the one, and oil pump need connect external power supply, power consumption, but also need a cover automatic control system to operate; Complex structure; In case control system breaks down, Lubricating-oil Station can't be worked, to hydraulic turbine generator group operation deleterious impact.The 2nd, technical water supply has silt can cause the pipeline blockage in the cooler, influences cooling effect.
Therefore those skilled in the art are devoted to develop a kind of simple in structure, hydraulic generator unit oil circulation system that reliability is high.
The model utility content
Because the above-mentioned defective of existing technology, the utility model technical problem to be solved provides a kind of simple in structure, hydraulic generator unit oil circulation system that reliability is high.
For realizing above-mentioned purpose, the utility model provides a kind of hydraulic generator unit lubricant oil external circulating system, comprises power plant tail water chamber and hydraulic generator unit; Said hydraulic generator unit is provided with radial-thrust bearing and radial bearing; The arranged outside of said radial bearing has flywheel; Be communicated with first oil inlet pipe and first oil outlet tube on the said radial-thrust bearing; Be communicated with oil inlet pipe and oil outlet tube on the said radial bearing; The arranged outside of said flywheel has screw pump; The line shaft of said screw pump is connected with said main shaft through coupling; Be connected with oil outlet tube and fuel sucking pipe on the said screw pump; Said oil outlet tube is communicated with said first oil inlet pipe and oil inlet pipe; Said fuel sucking pipe is communicated with said first oil outlet tube and oil outlet tube; The said tail water of said fuel sucking pipe pile warp chamber, and have the pipeline below the liquid level that is positioned at said tail water chamber.
For ease of fixing of screw pump, said screw pump passes through stent support on the terrace of generator set.
For improving cooling effect, be positioned at the indoor fuel sucking pipe pipeline of said tail water and be the labyrinth setting lubricant oil.
The beneficial effect of the utility model is:
(1) do not need independent power supply, practiced thrift the energy;
(2) only there are an oil pump and oil pipe in system, has saved complicated control system, and is simple in structure;
(3) the oil circuit piping bottom places the power plant tail water chamber, utilizes tail water that the deep fat in the pipeline is cooled off, and has saved cooler, has avoided the pipeline blockage problem in the cooler, and technical water supply system can be saved in the power station.
In a word, the utility model has improved unit operation reliability, designs simplification.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is that the A of Fig. 1 is to zoomed-in view.
Fig. 3 is the partial enlarged drawing at I place among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Like Fig. 1, Fig. 2 and shown in Figure 3, arrow is represented the current method of lubricant oil among the figure, and a kind of hydraulic generator unit lubricant oil external circulating system comprises power plant tail water chamber 15 and hydraulic generator unit 1.Hydraulic generator unit 1 is provided with radial-thrust bearing 2 and radial bearing 3, and the arranged outside of radial bearing 3 has flywheel 5.Be communicated with first oil inlet pipe 6 and first oil outlet tube 7 on the radial-thrust bearing 2, be communicated with oil inlet pipe 8 and oil outlet tube 9 on the radial bearing 3;
The arranged outside of flywheel 5 has screw pump 10, and screw pump 10 is supported on the terrace 17 of generator set through support 16.The line shaft 11 of screw pump 10 is connected with main shaft 4 through coupling 12.
Be connected with oil outlet tube 13 and fuel sucking pipe 14 on the screw pump 10.Oil outlet tube 13 is communicated with oil inlet pipe 8 with first oil inlet pipe 6, and fuel sucking pipe 14 is communicated with oil outlet tube 9 with first oil outlet tube 7.Fuel sucking pipe pile warp tail water chambers 15 14, and have the pipeline below the liquid level that is positioned at tail water chamber 15.Fuel sucking pipe 14 pipelines that are positioned at tail water chamber 15 are the labyrinth and are provided with.
When generator set moves; 10 work of main shaft 4 rotation drive screw pumps; Screw pump is transported to the cold oil of power plant tail water chamber 15 on the 3 li coolings of radial-thrust bearing 2 and radial bearing and the lubricated bearing shell of hydraulic generator unit, and the deep fat that flows out from bearing shell flow back into 15 backs, power plant tail water chamber by the road and gets into next work cycle.Because screw pump 10 is connected with set main shaft 4, drive by main shaft 4 rotations, therefore do not need independent power supply, practiced thrift the energy.Only there are an oil pump and oil pipe in system, has saved complicated control system, and is simple in structure.In addition, because the oil circuit piping bottom places the power plant tail water chamber, utilize tail water that the deep fat in the pipeline is cooled off, saved cooler, avoided the pipeline blockage problem in the cooler, technical water supply system can be saved in the power station.
