Abstract
A lubricating protector for booster is composed of cylindrical casing, elastic oil storage bag in the internal cavity of casing, oil inlet and outlet communicated with main oil channel and oil supply port of booster, and check valve at oil inlet. The utility model discloses use with the oil pump cooperation, normal during operation, be full of lubricating oil in the oil storage bag, in case the oil pump is out of order, the main oil duct fuel cut off, then the oil storage bag contracts under the spring action, replenishes the oil storage rapidly for the booster, and fuel feeding time lasts 3 ~ 5 minutes, and fuel feeding pressure can be greater than 0.1MPa, and the operative employee has enough time to shut down to avoid causing the serious loss.
Description
Technical field
The utility model relates to a kind of diesel lubrication oil oil supplying device, especially for the pressurized machine lubrication protection device of supercharged diesel engine.
Background technique
Turbosupercharger is to utilize the exhaust energy of engine emission, promotes the turbine high speed rotating, thereby drives the compressor impeller high speed rotating coaxial with turbine, and with the compressed machinery of supply engine work after the compresses fresh air.It increases the motor aeration quantity, can supply more fuel oil fully burn, thereby has improved the power of motor, has reduced the harmful components discharging.Use in the plateau section, can effectively compensate the power of decline.Pressurized machine is comparatively accurate parts, good lubricated be the key that improves pressurized machine and diesel engine working life.
Supercharged diesel engine in use, when the diesel engine high loaded process and turbo charger speed when very high, though of short duration a few minutes no matter which kind of reason causes oil pump to quit work, will cause damage of bearings to turbo-charger bearing fuel feeding deficiency.Even the operator finds oil-break immediately, also have little time to shut down, pressurized machine causes lubricated the interruption because of oil path failure, and the phenomenon of Sun Huaiing is of common occurrence at short notice, has both caused bigger economic loss, influences the normal use of diesel engine simultaneously again.
The model utility content
The technical problems to be solved in the utility model is to overcome existing oil supplying device because of the oil pump fault; interrupt fuel feeding; the deficiency that causes pressurized machine to damage; provide that a kind of and oil pump be used pressurized machine lubrication protection device; use this device, meet the main oil gallery oil-break, but the short time is interior to the pressurized machine fuel feeding as prominent; guarantee that the operator in time shuts down repairing, avoid causing greater loss.
The technical solution of the utility model is: pressurized machine lubrication protection device mainly by shell, be located at the elasticity oil storage bag in the shell inner cavity and constitute into and out of hydraulic fluid port; shell is cylindric; gapped between oil storage bag and the shell; the inner chamber of oil storage bag is by being connected with the oil-feed port of main oil gallery and pressurized machine respectively into and out of hydraulic fluid port, and the filler opening position is provided with one-way valve.
Further scheme is: shell is spliced into one by upper casing and lower casing; Shell inner cavity one end is provided with the pilot sleeve of coaxial line with it, the sleeve root with link to each other into and out of hydraulic fluid port, the socket port place inserts guide rod, described oil storage bag two ends are adjacent to sealing with the periphery of pilot sleeve and guide rod respectively; Oil storage bag and sleeve and guide rod are adjacent to the position and are provided with fastening ring; Oil storage bag is the silicone rubber capsule.
Adopt this device, during proper functioning, be full of lubricant oil in the oil storage bag, in case the oil pump fuel cut-off, then oil storage bag oil outlet pressure reduces, and under the elastic force effect of cyst wall, oil storage replenishes fuel feeding to pressurized machine rapidly in the capsule, not the unexpected oil-break of reason and causing damage.
Description of drawings
Accompanying drawing is the utility model structural representation, and dotted line is represented the state of silicone rubber capsule after oil-filled among the figure.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing.
Cylinder-like shell is spliced by upper casing 1 and lower casing 5, and its inner chamber one end is provided with pilot sleeve 9, and the sleeve root links to each other with filler opening 6, oil outlet 8, is provided with one-way valve 7 in the filler opening.The guide rod 3 of socket port place insertion activity.Oil storage bag 4 two ends that made by silicone rubber are enclosed within respectively on the periphery of pilot sleeve and guide rod, are adjacent to sealing each other, and are provided with fastening ring 2, guarantee oil-proof.When oil storage bag is not oil-filled, shown in solid line among the figure, and enough gaps are arranged between the shell.During work, filler opening 6 is connected with main oil gallery, and oil outlet 8 is connected by the oil-feed port of screw thread and pressurized machine, under main oil gallery pressure, and one-way valve opens, lubricant oil is full of the oil storage bag inner chamber, and silicone rubber evenly expands until outer casing inner wall, as shown in phantom in FIG..Silicone rubber good springiness, oil resistance, shell then can prevent the excessive back explosion of its oil-filled expansion.As the prominent oil pump fault of meeting, the main oil gallery oil-break, then oil outlet place pressure reduces, and oil storage bag shrinks under the elastic force of silicone rubber, and oil storage in the capsule is extruded, and replenishes rapidly to pressurized machine, and at this moment the filler opening closed check valve stops oil return.Pilot sleeve and guide rod can guarantee oil storage bag expansion, shrink evenly smooth and easy.Sustainable 3～5 minutes of the fuel feeding process of oil storage bag, charge oil pressure can be greater than 0.1MPa, during this period of time in, pressurized machine continues to be lubricated, the operator has the enough time to shut down, to avoid causing heavy losses.
