Description
Technical field
The present invention relates to a kind of equipment of make-up oil, especially relate to and a kind of fuel injection helical lobe compressor is lubricated the fuel injection helical lobe compressor lubricant oil ancillary equipment that oil subsidy fills.
Background technique
The present tame fuel injection helical lobe compressor in the whole nation existing more than 100 manufacturer,
To the fuel injection helical lobe compressor make-up oil time, because the structural limitations of helical-lobe compressor all can only adopt and shut down make-up oil technology.There is following problem in this technology:
The repairing time lag of a, shutdown make-up oil technology is long; in order to keep the lubricant oil of long-time normal consumption in service; each lubricants capacity that replenishes is bigger; cause the lubricants capacity that recycles in the compression process big; and prolongation with working time; oil is variation constantly, reduces its lubricated cooling effect.
The helical-lobe compressor continuous operating time of b, shutdown make-up oil technology is short, the working environment of incompatibility long-time continuous operation.Simultaneously, the safe and stable operation that is unfavorable for helical-lobe compressor.
C, the condensed water of separating out in the pressurized air when helical-lobe compressor of shutting down make-up oil technology is shut down at every turn can cause emulsification of lubricating oils, shorten lubricant oil working life.The lubrication oil consumption that the operation of discharging condensed water causes when shutting down simultaneously, at every turn is bigger.
D, because the effect of fuel injection helical lobe compressor lubricant oil is the temperature of rotor, the gas the seal compression chamber in and the cooled compressed gas of lubricate compressors, and the circulation of its lubricant oil dependence is the pressure difference of compressor suction and discharge.After the long-time shutdown of helical-lobe compressor; the pressure difference of lubrication oil circulation is not kept in the suction and discharge of compressor compresses machine; originally breaking away from rotor attached to the epitrochanterian lubricant oil of compressor under the effect of gravity falls into bottom the compressor; the rotor of lubricate compressors, the gas in the seal compression chamber when guaranteeing that compressor starts again; must be earlier to the helical-lobe compressor make-up oil; and at this moment; aspirating air pipe that must the dismantling screw compressor could be the helical-lobe compressor make-up oil, makes complex operation.
Summary of the invention
Technical problem to be solved by this invention provides a kind of fuel injection helical lobe compressor lubricant oil ancillary equipment that can online make-up oil.
The technical solution adopted for the present invention to solve the technical problems is: fuel injection helical lobe compressor lubricant oil ancillary equipment, comprise helical-lobe compressor and deaerator by pipeline connection, on the pipeline between helical-lobe compressor and the deaerator, be arranged in parallel the oil storage cylindrical shell, the inlet end connecting screw rod compressor of oil storage cylindrical shell and the pipeline between the deaerator, outlet end communicates with deaerator.
Further be to be provided with the oil extraction control valve at the outlet end of oil storage cylindrical shell.
Further be to be provided with air intake valve at the inlet end of oil storage cylindrical shell.
Further be, the outlet end of described oil storage cylindrical shell communicates with the suction end of helical-lobe compressor, the oil storage cylindrical shell with respect to the height of ground level greater than the suction end of helical-lobe compressor height with respect to ground level.
Further be to be provided with separator refueling control valve at the filler opening place of deaerator.
Further be that the pipeline that the outlet end of oil storage cylindrical shell communicates with the suction port of helical-lobe compressor is provided with suction end refueling control valve.
Further be to be provided with fuel door at the top of oil storage cylindrical shell.
Further be that the barrel of oil storage cylindrical shell is provided with the oil level identification piece.
The invention has the beneficial effects as follows: by being arranged in parallel the oil storage cylindrical shell on the pipeline between helical-lobe compressor and the deaerator, making can be when helical-lobe compressor be worked, and lubricant oil is added in the oil storage cylindrical shell helical-lobe compressor is lubricated oil subsidy and fills.After can effectively avoiding the too many lubricant oil of disposable adding, cause the long-time decline of using the back quality of lubrication oil, guaranteed the quality of lubrication oil circulation between the spreadable life, prolong lubricant oil working life, can reduce lubricating oil consumption 40～60%; And can improve helical-lobe compressor and move the operating time continuously, be particluarly suitable for promoting the use of on the fuel injection helical lobe compressor.
