Description
Technical field
The utility model relates to a kind of natural gas compressor lubrication system.
Background technique
Compressor is of many uses, almost spreads all over industrial or agricultural, communications and transportation, national defence, the every field of life even.The reliability of compressor (particularly big-and-middle-sized compressor) is consistent with working life to be paid close attention to by the people.
Affect in the various factors in compressor reliability and life-span, the fault that fretting wear causes has accounted for sizable ratio.In the wear process of friction pair, except the factors such as size of Material selection, load, the lubrication circumstances of rubbing surface for rate of wear impact significantly.For a friction pair reasonable in design, as process, assembling to be qualified, the quality of lubrication circumstances has directly determined the length in its life-span.Have data to show: the wearing and tearing of machinery 65%～80% occur in the machinery initial start stage (this not only compressor be so, be not always the case as automobile, lathe etc. for other machineries).Analyze its reason, mainly contain the following aspects:
1, machinery out of service after, the lubricant oil overwhelming majority of surface of friction pair has been back to cabinet bottom, rubbing surface is only remaining a small amount of lubricant oil, when machinery starts again, lubricant oil has little time to reach each friction pair, and rubbing surface is similar to the oil-free lubrication state, and the wearing and tearing nature can increase the weight of;
When 2, machinery was shut down, the pressure of lubricant oil and delivery volume all descended rapidly, and some impurity that produce in mechanical movement can not be taken away by lubricated oil, some is deposited between rubbing surface, when machinery initial start stage again, the impurity that is deposited on rubbing surface will serve as abrasive material, accelerates the wearing and tearing of friction pair;
3, the mechanically activated initial stage, rotating speed can not arrive rated speed at once, and lubricating oil pressure does not arrive specified value yet, and the lubricant oil delivery volume is also not as good as normal operating condition, so the oil film of assurance friction pair normal operation is difficult to form;
4, the mechanically activated initial stage, the temperature of friction pair does not arrive normal working temperature, and the matching gap of friction pair does not arrive ideal value, inevitable accelerated wear test.
The model utility content
The purpose of this utility model is: propose a kind of novel natural gas compressor lubrication system, reduce the wearing and tearing of compressor bank initial start stage, improve reliability, extend friction pair working life.
The purpose of this utility model realizes by following technical proposals:
A kind of natural gas compressor lubrication system, the compression owner lubrication system that comprises compressor PLC automatical control system and be electrically connected and control, described compression owner lubrication system comprises main oil pump and main oil gallery, also comprise with described compressor PLC automatical control system and being electrically connected to, and control by it pre-lubrication system that stops prior to after parallel running a period of time after the startup of described compression owner lubrication system, described pre-lubrication system comprises the pre-lubrication oil pump that is arranged in parallel with described main oil pump, and it is communicated to described main oil gallery by lubricating oil pipeline through the lubricant oil fine filter.
As optimal way, described pre-lubrication system also is provided with machine monitoring device and the device for monitoring running that is electrically connected to described compressor PLC automatical control system respectively, whether described compressor PLC automatical control system plays the described pre-lubrication pump start of machine state signal control according to the pre-lubrication system of described machine monitoring device feedback, and further whether controls compressor start according to the pre-lubrication system operating state signal of described device for monitoring running feedback.
Workflow of the present utility model: after compressor PLC automatical control system has been received the machine instruction, at first compressor PLC automatical control system plays the machine state signal according to the pre-lubrication system that plays machine monitoring device feedback, whether play the machine condition by detection possesses, meet the requirements as playing the machine condition, system takes the lead in starting the pre-lubrication oil pump.During the pre-lubrication operation of oil pump, the PLC system is according to the pre-lubrication system operating state signal of device for monitoring running feedback, monitoring pre-lubrication system running state.If any abnormal conditions, compressor PLC automatical control system will be controlled shutdown, make Compressor Group turn back to the startup original state; If all are normal, when the pre-lubrication system running state reaches setting value, compressor PLC automatical control system is carried out follow-up machine program, program control startup compressor host.This moment pre-lubrication system will with the compression owner's lubrication system parallel running a period of time, complete to unit starting, after entering normal operating condition, the pre-lubrication oil pump quits work.
The use of pre-lubrication system has improved the lubricating condition of compressor bank initial start stage greatly.At first, carried a large amount of lubricant oil to each surface of friction pair before host-initiated due to pre-lubrication system, thoroughly changed the approximate without oil condition of rubbing surface, made friction pair obtain reliable lubricant oil and supply with; Secondly, the lubricant oil of a large amount of cleanings are transported to each friction surface of machinery, have washed away the various impurity that deposited when shutting down last time, and make each rubbing surface obtain good cleaning and lubricated before again putting into operation; In addition, in playing the machine process, pre-lubrication oil pump and main oil pump have one period overlapping operating time, host-initiated accelerated service just during this period of time, and the time that oil film is difficult to form.Because two oil pumps are worked simultaneously, lubricating oil pressure is 1.5～2 times of when normal operation, some rubbing surfaces (as crosshead and guide rail), can be held up because enough lubricating oil pressures are arranged or part holds up (at idling lotus, lower-speed state), this just part made up oil film and not yet formed the excessive wear that may bring to rubbing surface.
The beneficial effects of the utility model: the application's natural gas compressor lubrication system, can reduce significantly compressor bank initial start stage wearing and tearing, improve reliability, extend friction pair working life.
