Abstract
The utility model relates to a lubricating oil double-tank system arranged in a high-low mode. Two lubricating oil tanks of the lubricating oil double-tank system are arranged respectively. One lubricating oil tank is arranged on an electric generator layer which is higher than a big shaft, and the lowest portion of the oil tank is higher than the highest portion of an inner shell of a main oil pump. The other oil tank is arranged on an auxiliary machine layer which is lower than the big shaft, the highest portion of the oil tank is lower than the lowest portion of the inner shell of the main oil pump, namely heavy loss of bearing bush burning and shaft damaging caused by the condition that lubricating oil is cut off in operation sometimes due to reasons such as cavitation of the main oil pump is prevented fundamentally, and maintaining is convenient.
Description
Technical field
The technological scheme that the utility model is applied for relates to a kind of power station auxiliary system, the lubricant oil two-bin system that especially height is arranged.
Background technique
At present, steam turbine of thermal power plant is in actual motion, there is the hidden danger of lubricant oil cutout, according to current design, lubricant oil main oil pump is supplying lubricating oil in the time of steam turbine operation, the entrance of main oil pump is at lubricating oil tank, and the lubricant oil that 1 to 3 kilogram of pressure is supplied with in outlet, has played the effect of lubrication macro-axis and bearing shell.But, because main oil pump is inhaled the various reasons such as empty, there is sometimes the disconnected oil condition of lubricant oil in service, the heavy losses that cause tile kilning, ruin axle.The present invention proposes exactly and addresses this problem.
Summary of the invention
In order to overcome because main oil pump is inhaled the various reasons such as empty, there is sometimes the disconnected oil condition of lubricant oil in service, cause tile kilning, ruin the deficiency of the heavy losses of axle, the invention provides the lubricant oil two-bin system that a kind of height is arranged.
The technical solution adopted for the present invention to solve the technical problems is: comprise eminence lubricating oil tank, lower lubricating oil tank, return to oil pump, return to check valve and return pipeline, connection solenoid valve, be communicated with manually operated valve and connecting pipeline, 2 lubricating oil tanks are arranged respectively, one of them eminence lubricating oil tank is arranged in the generator floor higher than macro-axis, the lowest part of fuel tank is higher than the highest point of main oil pump inner casing, another lower lubricating oil tank is arranged in lower than the subsidiary engine layer of macro-axis whole, and the highest point of fuel tank is lower than the lowest part of main oil pump inner casing.
Between two lubricating oil tanks, have solenoid valve series connection manually operated valve, wherein the entrance of solenoid valve is communicated with the bottom of eminence oil pump, and the outlet of solenoid valve is communicated with the entrance of manually operated valve, and the outlet of manually operated valve is communicated with lower lubricating oil tank.
Lower volume of fuel tank is large enough to hold the oil in oil and the whole oil pipe line in all higher fuel tank.
The entrance that returns to oil pump is communicated to lower lubricating oil tank through returning to check valve, returns to oil pump outlet and is communicated with eminence lubricating oil tank, and unlatching is returned to oil pump oil is knocked down to higher case from lower case.
Comprise: solenoid valve dead electricity is closed.
Comprise: described in to return to pump be motor-drive pump.
Or: between two lubricating oil tanks, there is solenoid valve series connection manually operated valve, wherein the entrance of solenoid valve is communicated with the bottom of eminence oil pump, the outlet of solenoid valve is communicated with the entrance of manually operated valve, the outlet of manually operated valve is communicated with lower lubricating oil tank, oil return line parallel connection is maintenance bypass therewith, and this maintenance bypass is made up of traditional dual stop valve single by-pass valve of arranging in pairs or groups.
Comprise: be applied to the big machinery that comprises steam turbine, water turbine.
Its working principle is: 2 fuel tanks are arranged respectively, both prevented because main oil pump is inhaled the various reasons such as empty, there is sometimes the disconnected oil condition of lubricant oil in service, the heavy losses that cause tile kilning, ruin axle, convenient maintenance again, when maintenance, open solenoid valve and series connection manually operated valve between lubricating oil tank, the oil in higher fuel tank be all put into lower fuel tank by the oil in pipeline, overhaul bearing shell and lubricating oil system.
The invention has the beneficial effects as follows: 1, fundamentally prevented because main oil pump is inhaled the various reasons such as empty, the disconnected oil condition of lubricant oil in service has occurred sometimes, the heavy losses that cause tile kilning, ruin axle; And by contrast, prior art is inhaled the various reasons such as empty due to main oil pump, there is sometimes the disconnected oil condition of lubricant oil in service, the heavy losses that cause tile kilning, ruin axle.2, convenient maintenance, opens solenoid valve and series connection manually operated valve between a lubricating oil tank when maintenance, the oil in higher fuel tank be all put into lower fuel tank by the oil in pipeline, overhaul bearing shell and lubricating oil system; And by contrast, prior art is not easy to maintenance.Thereby the utility model not only Security is high, and maintenance is convenient.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is embodiment one schematic diagram.
1. 1 steam turbine main shafts in figure, the 2. highest point of main oil pump inner casing, 3. higher lubricating oil tank lowest part, the 4. lowest part of main oil pump inner casing, 5. lower lubricating oil tank highest point, 6. solenoid valve series connection manually operated valve, 7. oil pump.
