Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-10:
High pressure lubricator, comprise oil-storing barrel 1, the plunger-type fuel pump 5 that air motor and air motor drive, the bottom of supporting base 3 is connected with the bung 2 of described oil-storing barrel, top is connected with the base of described air motor, described plunger-type fuel pump 5 is arranged in oil-storing barrel, the upper end of the plunger 6 in plunger-type fuel pump is connected with extension bar 7, extension bar is connected with the piston 8 of the driving cylinder 4 of air motor through supporting base, on described supporting base, offer the oil outlet 9 that is communicated with plunger-type fuel pump epicoele, described air motor drives the upper of cylinder piston, bottom offset drives the plunger motion of plunger-type fuel pump to suck the grease in oil-storing barrel and grease is transported to the oil outlet of supporting base by plunger-type fuel pump epicoele.
Working principle of the present utility model is:
Air motor is kinetic pump, drives that plunger-type fuel pump is reciprocating reaches oil-feed, fuel-displaced with compressed air-driven air motor, and produces oil pressure effect.Because the cylinder piston net sectional area of air motor is larger than the cylinder body useful area of plunger-type fuel pump, therefore can reach the effect that increases pressure, both often claim pressure ratio than for 85:1 by useful area, in the time sending into the pressurized air of 0.6 MPa, can make output oil pressure reach 51 MPas and disregard loss.The power of plunger-type fuel pump derives from air motor completely, and the two is connected by extension bar 7, with the piston synchronous to-and-fro motion of cylinder in air motor, in the process of motion, oil plant is sucked, and in limited space, oil plant constantly increases, thereby produces high pressure output.Its moving situation is as follows: extension bar is connecting plunger, the plunger material extraction rod of ining succession, and material extraction rod is ined succession and is carried flitch.In the time carrying flitch and up move, oil plant is sent into oil inlet pipe upper end, move downward and get back to original position when carrying flitch, oil plant again enters oil inlet pipe and carries between flitch.
In above-mentioned high pressure lubricator, described air motor comprises the control mechanism that drives cylinder and control to drive cylinder to move back and forth: on the cylinder wall of driving cylinder, axially offer two mounting holes, balance valve core 44 is all installed in each mounting hole, described cylinder wall be provided be communicated with two mounting holes and can with the suction port 41 that is connected source of the gas, on the sidewall of described mounting hole, offer to be communicated with and drive the inlet and outlet hole 42 of cylinder inner cavity and be communicated with extraneous exhaust port 43, source of the gas drives moving back and forth and then control and driving moving back and forth of cylinder of balance valve core.
The working principle of the control mechanism that above-mentioned driving cylinder and control driving cylinder move back and forth is: two groups of balance valve cores are installed in the mounting hole of cylinder wall, on cylinder wall, there are two groups of apertures to lead to two groups of balance valve cores, in inflation/deflation process, balance valve core forms draught head, under the promotion of draught head, balance valve core moves reciprocatingly, rely on the principle of connecting vessels, there is too draught head in cylinder two ends, also to-and-fro motion under the promotion of draught head, when connecting rapid pipe joint, pressurized air is through entering the balance valve core of cylinder interior to air input joint, any one section of balance valve core and piston body carried out to pressurising, balance valve core and piston body move by same direction simultaneously, therefore mineralization pressure is poor, the position of going to vent hole when the balance valve core in left side will discharge internal pressure, the position that the balance valve core on right side is gone to vent hole discharges internal pressure completely, the balance valve core in left side repeats again the movement process of the balance valve core on right side, form like this cycle of motion, as long as to cylinder charge, this to-and-fro motion of air motor will continue.
Referring to Fig. 9, in figure, state is that piston is moved down into upper/lower positions, be that piston upwards pushes up uppermost position in fig-ure referring to state in Figure 10 figure, the workflow of the control mechanism that above-mentioned driving cylinder and control driving cylinder move back and forth is:, the pressurized air of piston below moves upward the balance valve core jack-up on right side by aperture 45, now, the rising of right side balance valve core make into, exhaust port 42 and exhaust port 43 are communicated with, the pressurized air of piston top is discharged by the exhaust port 43 on right side, the pressure of piston top reduces, the pressurized air of balance valve core upper end, left side is discharged pressure minimizing by aperture 45 simultaneously, left side balance valve core rises, after rising, left side balance valve core closes exhaust port 43 simultaneously by entering, exhaust port 42 moves upward piston to gas injection in cylinder, aperture 45 positions on the left of piston moves up to, producing pressure moves downward left side balance valve core, make the exhaust port 43 in left side start exhaust, balance valve core lower end, right side pressure reduces simultaneously, right side balance valve core declines and makes entering of right side, exhaust port 42 starts air inlet and pushes piston and move downward, said process continues air feed to cylinder, can realize piston continue on, lower to-and-fro motion.
Above-mentioned suction port 41 is communicated with respectively mounting hole, is positioned at the middle part 46 of balance valve core, and wherein the both sides at balance valve core middle part are equipped with seal ring, and after balance valve core packs mounting hole into, middle part forms air cavity, offers through hole and form gas injection runner 47 on balance valve core.
The concrete structure of described plunger-type fuel pump is: comprise the adapter 10, upper oil pipe 11 and the oil inlet pipe 12 that connect to form the pump housing from top to bottom, in the pump housing, be provided with extension bar 7, plunger 6, the material extraction rod 13 connecting successively from top to bottom and carry flitch, extension bar also and between nozzle inner wall leaves gap 14 in taking over; Plunger is positioned at oil pipe and is close to sealing with the inwall of upper oil pipe upper end, offers axial oil-through hole 15 on plunger, and the bottom of oil-through hole is provided with one-way valve 16; Material extraction rod is positioned at oil inlet pipe, in oil inlet pipe, be provided with oil screen 17 and safety check 18, settings that be connected with gap in adapter and supporting base oil outlet of oil-through hole in oil inlet pipe, plunger, extension bar, drive cylinder piston lifting drive extension bar, plunger material extraction rod and carry flitch move make to carry flitch by grease successively by delivering to the oil outlet of supporting base after the mesopore supercharging on material extraction rod, plunger, extension bar.
