Below in conjunction with embodiment and with reference to accompanying drawing the utility model is further described.
Please referring to Fig. 1, Fig. 1 is a kind of dry oil lubrication apparatus structure schematic representation that adapts to multi-operating mode, and the dry oil lubrication device of described adaptation multi-operating mode comprises A1 pipeline 21, A2 pipeline 22, A3 pipeline 23, A4 pipeline 24, B1 pipeline 21, B2 pipeline 22, B3 pipeline 23, B4 pipeline 24, the lubricating point 1 of need oil mass maximum, the lubricating point 2 that demand is less, need the bigger lubricating point 3 of oil mass, normal demand amount lubricating point 4, differential pressure switch 5, drier oil distributor 6, ball valve 7, shuttle valve 8, selector valve 9 for the first time, selector valve 10 for the second time, main reversing valve 11, filter 12, relief valve 13, lubricant pump 14, fuel tank 15.Described lubricating point 1 one ends of oil mass maximum that need connect ball valve 7, ball valve 7 connects shuttle valve 8, shuttle valve 8 is connected selector valve 9 for the first time by A2 pipeline 22 with B2 pipeline 32, selector valve 9 is connected to main reversing valve 11 for the first time, main reversing valve 11 connects filter 12, filter 12 connects relief valve 13 and lubricant pump 14, and relief valve 13 is connected fuel tank 15 with lubricant pump 14.Described lubricating point 1 the other end of oil mass maximum that needs is connected to main reversing valve 11 by A4 pipeline 24 and B4 pipeline 34, and main reversing valve 11 connects filter 12, and filter 12 connects relief valve 13 and lubricant pump 14, and relief valve 13 is connected fuel tank 15 with lubricant pump 14.The less lubricating point 2 of described demand is connected to drier oil distributor 6 by A3 pipeline 23 and B3 pipeline 33, drier oil distributor 6 connects selector valve 10 for the second time, selector valve 10 connects main reversing valve 11 for the second time, main reversing valve 11 connects filter 12, filter 12 connects relief valve 13 and lubricant pump 14, and relief valve 13 is connected fuel tank 15 with lubricant pump 14.Need oil mass bigger lubricating point 3 to be connected main reversing valve 11 by A4 pipeline 24 with B4 pipeline 34, main reversing valve 11 connects filter 12, and filter 12 connects relief valve 13 and lubricant pump 14, and relief valve 13 is connected fuel tank 15 with lubricant pump 14.Normal demand amount lubricating point 4 is connected main reversing valve 11 by A4 pipeline 24 with B4 pipeline 34, and main reversing valve 11 connects filter 12, and filter 12 connects relief valve 13 and lubricant pump 14, and relief valve 13 is connected fuel tank 15 with lubricant pump 14.Differential pressure switch 5 is built up in the least significant end of pipeline A4 and pipeline B4, and the coil of selector valve 9 is the coil K4 that time relay kT2 is controlled for the first time, and the coil of selector valve is the coil K5 that time relay kT3 is controlled for the second time.
The utility model perforate welding on original drier oil is responsible for has increased A2 pipeline 22 and B2 pipeline 32 two-way are responsible for, by the opening and closing that the first time, selector valve 9 came control valve, selector valve 9 connects shuttle valve 8 for the first time, make that A2 pipeline 22 and B2 pipeline 32 are not connected, under the situation that ball valve 7 is opened, no matter which person in charge's work can both can realize manual control at the ball valve 7 that shuttle valve 8 backs are inserted to the lubricating point automatic oiling, close ball valve 7 back automatic oilings and cease to be in force automatically.Another branch road of this lubricating point is original lubricating pipe, and after automatic oiling stopped, distributor work was to lubricating point self oiling.
A kind of work that adapts to the dry oil lubrication device of multi-operating mode: start lubricant pump 14, oil in the fuel tank 15 passes through lubricant pump 14 pump pressures, extremely needs in the lubricating point 1 of oil mass maximum through main reversing valve 11, A1 pipeline 21, selector valve 9, A2 pipeline 22, shuttle valve 8 and ball valve 7 automatically big flows oilings for the first time.Behind time of advent relay K T2 set time, selector valve 9 coil K4 get electricly for the first time, and selector valve cuts out, and stops to refuel to the automatically big flow of lubricating point.Flow of lubricant is through A3 pipeline 23, A4 pipeline 24, and all distributors begin to move successively in the system, realizes self oiling.Behind time of advent relay K T5 set time, selector valve 10 coil K5 get electricly for the second time, and selector valve 10 cuts out, and selector valve 10 all distributors of back quit work, and stop to refuel to the less lubricating point 2 of demand.(can determine in this design the number of the less lubricating point 2 of demand by the number of selector valve 10 back drier oil distributors.) when the pressure difference value in A4 pipeline 24 and the B4 pipeline 34 reaches setting value, the action of differential pressure switch 5 contacts, main reversing valve 11 commutations, oil in the fuel tank 15 passes through lubricant pump 14 pump pressures, extremely needs in the lubricating point 1 of oil mass maximum through main reversing valve 11, pipeline B1, selector valve 9, pipeline B2, shuttle valve 8 and ball valve 7 automatically big flows oilings for the first time.Behind time of advent relay K T2 set time, selector valve 9 coil K4 get electricly for the first time, and selector valve cuts out, and stops to refuel to the automatically big flow of lubricating point.Flow of lubricant is through B3 pipeline 33, B4 pipeline 34, and all distributors begin to move successively in the system, realizes self oiling.Behind time of advent relay K T5 set time, selector valve 10 coil K5 get electricly for the first time, and selector valve 10 cuts out, and selector valve 10 all distributors of back quit work, and stop to refuel to the less lubricating point 2 of demand.When the pressure difference value in A4 pipeline 24 and the B4 pipeline 34 reaches setting value, the action of differential pressure switch 5 contacts, main reversing valve 11 commutations, system quits work, and forms an operation cycle.After reaching set time, system resets automatically, and carries out next cycle, and constantly periodic duty and so forth realizes self oiling.
Need to prove: time set sees also Fig. 2 in the utility model, and KT1 (coil) is the blanking time of system between two cycles; KT2 (coil) is that automatically big flow refuels the needed time in the lubricating point 1 of oil mass maximum that extremely needs, and needs the oil mass decision by lubricating point; KT3 (coil) is the maximum time of working in the lubricant pump one-period, surpasses this time, and system sends auto alarm signal.KT4 (coil) is for setting the time span that alarm bell rings; KT5 (coil) automatic oiling needs the oil mass decision to needing the needed time in the less lubricating point 2 of oil mass by lubricating point.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement and replenish, these improvement and replenish and also should be considered as protection domain of the present utility model.
