By using technique scheme, lubricating oil enters in oil-collecting annular groove by fuel feed hole, its lubricating oil portion can penetrate on plunger oilhole from drenching, remaining major part is filled in oil-collecting annular groove, this major part lubricating oil enters in pouring oil ring groove by the pouring oilhole being circumferentially distributed on rear fairlead afterwards, lubricating oil is disposably entered from each orientation in thus making to drench oil ring groove, and quickly contact with the surface of plunger, plunger operationally can just be contacted with the lubricating oil on rear fairlead the very first time, thus plunger is played lubrication, and then make plunger can be maintained at the service life moving back and forth to extend plunger under lubricating status.
This utility model is further arranged to: described pouring oilhole is set to six.
By using technique scheme, pouring oilhole is set to six, make the pouring oilhole that just can have oil-feed on rear fairlead every 60 °, on the one hand it is unlikely to cause lubricating oil quickly to run off too much because drenching oilhole, on the other hand six drench oilhole and do not interfere with the structural strength of rear fairlead, with the stable operation of fairlead after ensureing.
This utility model is further arranged to: be provided with the first driving pulley on described oil syringe, and the bent axle on described pump housing fuselage is provided with the second driving pulley, and described first driving pulley and the second driving pulley are connected by belt transmission.
By using technique scheme, oil syringe is rotated the second driving pulley originally that be arranged through on bent axle by the extra driven by motor arranged is driven the first driving pulley to rotate by the gearing of belt, thus driving oil syringe rotation work so that cost reduces.
Compared with prior art, this utility model has the advantages that lubricating oil flows through fuel feed hole and enters on pouring oil machine structure, by drenching oil machine structure, lubricating oil is evenly distributed in each orientation of rear fairlead, plunger operationally can just be contacted with the lubricating oil on rear fairlead the very first time, thus plunger plays lubrication, and then make plunger can be maintained at the service life moving back and forth to extend plunger under lubricating status.
