Description
Technical field
The utility model relates to the LNG device Systems of Centrifugal Compressor Unit lubricating oil station that a kind of major-minor oil pump is communicated with.
Background technique
Under nominal situation, main oil pump runs, and auxiliary oil pump is stopped using, and when main oil pump fault or other reason cause system oil to force down, system is provided with low oil pressure interlocked startup auxiliary oil pump to ensure that oil pressure is normal.But due to auxiliary oil pump Long-time Shut-down in actual motion, difficulty in starting, particularly severe cold area in the winter time, in auxiliary oil pump, medium temperature is low, oil viscosity is large, cause auxiliary oil pump inrush current large, generally when oil temperature can not start (overseas equipment generally has low oil temperature to interlock) lower than oil pump when 15 DEG C at all; The pressure reduction of oil screen is comparatively large, and oil pump may be found time, and above reason all likely causes auxiliary oil pump normally to start; as auxiliary oil pump can not normally start; system oil is forced down and shake-up compressor bank is shut down interlocking, affects factory's long-period stable operation, brings economic loss.
Summary of the invention
Arrange existing deficiency in order to what overcome above-mentioned auxiliary oil pump, the utility model provides and a kind ofly effectively can ensure that auxiliary oil pump can normally start and the Systems of Centrifugal Compressor Unit lubricating oil station that is communicated with of stable major-minor oil pump.
The technological scheme that the utility model adopts is: comprise fuel tank, main oil screen, auxiliary oil screen, main oil pump and auxiliary oil pump, wherein the oil outlet of fuel tank is communicated with auxiliary oil pump with main oil pump with auxiliary oil screen respectively by main oil screen, the outlet line of main oil pump is provided with the first discharge control valve, the outlet line of auxiliary oil pump is provided with the second discharge control valve, the outlet end of the first discharge control valve and the outlet end of the second discharge control valve pass through pipeline connection, the reflow pipe by main oil pump and auxiliary oil pump pipeline connection is provided with between the entry end of outlet line first discharge control valve of main oil pump and the entry end of outlet line second discharge control valve of auxiliary oil pump, reflow pipe is provided with cut-off valve and stop valve.
The caliber of above-mentioned reflow pipe is less than the outlet line caliber of main oil pump and auxiliary oil pump.
The Systems of Centrifugal Compressor Unit lubricating oil station that major-minor oil pump of the present utility model is communicated with, that reflow pipe is set between main and auxiliary oil pump, and cut-off valve and stop valve are set on reflow pipe, a small amount of oil is had to pass back into auxiliary oil pump when allowing main oil pump run well, auxiliary oil pump is made to possess the same oil stream of same main oil pump working state, moment is standby, ensure that pump handoff procedure rapidly, steadily, pass back into auxiliary oil pump oil mass to regulate with stop valve, guarantee auxiliary oil pump is nonreversible, cut-off valve cuts off connection after being used for auxiliary oil pump startup normally, creates main oil pump maintenance condition.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Now in conjunction with the accompanying drawings and embodiments the technical solution of the utility model is further described, but the utility model is not limited only to following enforcement situation.
As shown in Figure 1, the Systems of Centrifugal Compressor Unit lubricating oil station that is communicated with of the major-minor oil pump of the present embodiment forms by by the fuel tank 1 of pipeline communication, main oil screen 2, auxiliary oil screen 10, main oil pump 3, auxiliary oil pump 9, first discharge control valve 4, second discharge control valve 6, reflow pipe 5, cut-off valve 7 and stop valve 8.
Wherein, the primary outlet of fuel tank 1 is communicated with the filler opening of main oil screen 2 by the primary outlet control valve be arranged on pipeline, the oil outlet of main oil screen 2 is communicated with by the oiling valve of pipeline with main oil pump 3, the lubrication oil filtration of fuel tank 1 laggard enter in main oil pump 3, the outlet line of main oil pump 3 is provided with the first discharge control valve 4, by the first discharge control valve 4 to Systems of Centrifugal Compressor Unit fuel feeding, simultaneously, the pilot outlet of fuel tank 1 is communicated with the filler opening of auxiliary oil screen 10 by the pilot outlet control valve be arranged on pipeline, the oil outlet of auxiliary oil screen 10 is communicated with by the oiling valve of pipeline with auxiliary oil pump 9, the outlet line of auxiliary oil pump 9 is provided with the second discharge control valve 6, by the second discharge control valve 6 to Systems of Centrifugal Compressor Unit fuel feeding.
Reflow pipe 5 is provided with between the entry end and the entry end of the second discharge control valve 6 of above-mentioned first discharge control valve 4, by the pipeline connection of main oil pump 3 with auxiliary oil pump 9, this reflow pipe 5 is provided with cut-off valve 7 and stop valve 8, the caliber of reflow pipe 5 is less than the outlet line caliber of main oil pump 3, also be less than the outlet line caliber of auxiliary oil pump 9 simultaneously, circulate between main oil pump 3 and auxiliary oil pump 9 to ensure a small amount of oil.
When main oil pump 3 runs well, open cut-off valve 7 and stop valve 8, a small amount of oil has been allowed to pass back into auxiliary oil pump 9 from main oil pump 3, auxiliary oil pump 9 is made to possess the same oil stream of same main oil pump 3 working state, moment is standby, ensure that pump handoff procedure rapidly, steadily, utilizes stop valve 8 to regulate and pass back into auxiliary oil pump 9 oil mass, ensure that auxiliary oil pump 9 is nonreversible; When main oil pump 3 fault, when can not run well, utilize cut-off valve 7 to cut off being communicated with between main oil pump 3 with auxiliary oil pump 9, create main oil pump 3 and keep in repair condition.
