Description
Technical field
The utility model relates to centrifuge field, specifically a kind of centrifuge oil supply system top petrol tank.
Background technique
The normal fuel injection of centrifuge is born by main oil pump.When unit normally runs; main oil pump starts, and lubricant oil enters lubricant housings by bottom, is discharging direct oil sump tank by top flow-off; once there is power failure machine halt trouble; auxiliary oil pump can not start fuel feeding again in time, but now blower fan, because its inertia is still at High Rotation Speed, thus very easily produces and grinds a watt accident; produce to enterprise and bring huge loss; top petrol tank effectively can avoid the generation of this type of accident, meets the needs to lubricant oil in compressor emergency shutdown process, ensures that unit safety stops.
Existing top petrol tank is positioned at the top of unit, main fuel tank and main oil pump are positioned at the bottom of unit, main oil pump is connected with unit by pipeline, be connected with top petrol tank by upper oil hole etc., top petrol tank is connected with main fuel tank, during centrifuge normal operation by a spill pipe simultaneously, main oil pump is to each lubricant housings fuel feeding, top petrol tank is oiled by upper oil hole by main oil pump pressure on fuel tank, gets back to main fuel tank again by spill pipe, and top petrol tank is in full oily stand-by state all the time.When having a power failure suddenly, main oil pump dead electricity can not run well, and top petrol tank relies on deadweight and the oil pressure of its internal lubrication oil, by the oil feed line of oil pump, forces, to each position fuel feeding, to impel the positions such as bearing shell normally to lubricate, thus the generation of accident such as stops to grind watt.
Owing to will ensure that the lubricant oil in top petrol tank can flow to downwards each lubricant housings by deadweight, therefore top petrol tank must arrange pneumostome, ensure that the atmospheric pressure of its inside is consistent with the external world, avoid producing negative pressure, cause lubricant oil not fall.After each machine halt trouble occurs, the oil level in top petrol tank will decline, and now needs to top petrol tank repairing.Existing repairing mode is all carry out repairing from bypass valve and upper oil hole to top petrol tank by high pressure oil pump.
There is a very large problem in existing repairing mode, the speed of repairing is difficult to consistent with the flow velocity of spill pipe, if repairing speed is too fast, the flow velocity entering fuel tank will be greater than the flow velocity of discharging fuel tank, cause the lubricant oil in top petrol tank to overflow from pneumostome, cause the waste of lubricant oil.If repairing speed is excessively slow, be just difficult to fuel tank to fill, and repairing overlong time, cause working efficiency to reduce.
Model utility content
It is too fast that the utility model is intended to provide one can solve top petrol tank repairing, and lubricant oil overflows the centrifuge oil supply system top petrol tank of the problem of fuel tank.
A kind of centrifuge oil supply system top petrol tank, comprise casing, bottom half is provided with oil inlet pipe, and side is provided with the spill pipe be connected with main fuel tank, described casing top is provided with a respirating tube communicated with the external world, and the outer wall of described respirating tube is provided with the oil pipe of a connection main fuel tank.
The beneficial effects of the utility model are:
The utility model arranges oil pipe on respirating tube sidewall, when repairing speed is greater than flooding velocity, lubricant oil can be back to main fuel tank from the oil pipe of respirating tube sidewall, thus minimizing lubricant oil overflows the waste caused, when repairing speed is normal, this oil pipe can not affect the running of whole oil circuit.
Further, described respirating tube embeds in casing, and the port being positioned at casing is provided with sealing cover, described sealing cover one end and respirating tube tube wall hinged, described sealing cover is that light plastic is made.
Sealing cover is made up of lightweight material, therefore can be floating on pasta, and when the lubricant oil in top petrol tank is comparatively expired, sealing cover floats, and blocks pneumostome, avoids the spilling of lubricant oil.When shutting down, when top petrol tank is to unit oiling, oil level declines, and sealing cover loses the buoyancy of lubricant oil, automatically opens, and keeps the unobstructed of respirating tube, thus ensures the normal operation of oil circuit.
Further, described casing is placed in an oil trap.
When repairing excessive velocities, when the oil pipe on spill pipe and respirating tube sidewall also has little time oil extraction, the oil gone out from respirating tube slime flux can be collected in oil trap, further, avoids the waste of lubricant oil.
Further, a pipeline be connected with main fuel tank is provided with bottom described oil trap.
Can automatic stream main fuel tank when there being oil-collecting in oil trap.
