Description
Technical field
The utility model relates to hydraulic cylinder, specifically a kind of double containment hydraulic cylinder concentrates oil return processing unit.
Background technique
Since hydraulic cylinder is industrial important and indispensable tool, cement plant is no exception, in raw material powder
Most of hydraulic cylinders in raw material roller mill in production system, in use for some time, it may appear that hydraulic cylinder head end oil sealing permeability is existing
As, it does not influence to produce, but pollute environment and consume hydraulic oil, improve production cost.
Utility model content
The technical issues of the utility model aims to solve the problem that is to provide a kind of double containment hydraulic cylinder concentration oil return processing unit, solution
Determined hydraulic cylinder head end oil sealing permeability the problem of.
The utility model solve its technical problem the technical solution adopted is that:
A kind of double containment hydraulic cylinder concentration oil return processing unit, including hydraulic cylinder, the end of the epicoele of hydraulic cylinder body are set
There are the first oil sealing and the second oil sealing, the side wall of the cylinder body between the first oil sealing and the second oil sealing is equipped with oil return hole, and oil return hole passes through
Oil return pipe is connected to fuel tank.
The utility model by adopting the above technical scheme, compared with prior art, beneficial effect is:
Structure is simple, easy for installation, protects environment, reduces hydraulic oil loss, reduces cost, practical.
Further, the prioritization scheme of the utility model is:
Oil return pipe includes the first oil return pipe, concentrates oil return pipe and the second oil return pipe, one end of the first oil return pipe and hydraulic cylinder
Oil return hole connection, the other end of the first oil return pipe is by concentrating oil return pipe to be connected to one end of the second oil return pipe, the second oil return
The other end of pipe is connected to fuel tank.
The height of first oil return pipe and concentration oil return pipe is all larger than the height of fuel tank upper surface.
Concentration oil return pipe is circular ring shape.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiments of the present invention.
In figure: the first oil sealing 1；Second oil sealing 2；Cylinder body 3；Piston 4；First connector 5；First oil return pipe 6；Second connector 7；
Concentrate oil return pipe 8；Second oil return pipe 9；Hydraulic cylinder 10；Fuel tank 11；Oil pump 12；Reversal valve 13.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Referring to Fig. 1, a kind of double containment hydraulic cylinder concentrates oil return processing unit, by the first oil sealing 1, the second oil sealing 2, cylinder body 3,
First connector 5, the second connector 7, concentrates oil return pipe 8, the second oil return pipe 9, hydraulic cylinder 10 and fuel tank 11 to constitute at first oil return pipe 6.
Hydraulic cylinder 10 is connected to by fluid pressure line with reversal valve 12, and reversal valve 12 is connected to by fluid pressure line with oil pump 12.
The piston 4 of hydraulic cylinder 10 is located at the cavity of resorption of cylinder body 3, and the end of the epicoele of cylinder body 3 is equipped with the first oil sealing 1 and the second oil sealing.The
The side wall of cylinder body 3 between one oil sealing 1 and the second oil sealing 2 is machined with oil return hole, and the first connector 5 is mounted on the oil return hole, the
One end of one oil return pipe 6 is connected to the first connector 5, and the other end of the first oil return pipe 6 is connected to the second connector 7, the second connector 7 peace
Mounted in concentrating on oil return pipe 8, the oil inlet of the first oil return pipe 6 is higher than the oil outlet of the first oil return pipe 6.Concentrating oil return pipe 8 is circle
The height of annular, the first oil return pipe 6 and concentration oil return pipe 8 is all larger than the height of 11 upper surface of fuel tank.The oil inlet of second oil return pipe 9
Mouth is connected to oil return pipe 8 is concentrated, and the oil outlet of the second oil return pipe 9 is connected to the oil return opening at 11 top of fuel tank.First oil sealing 1 and
The hydraulic oil leaked between two oil sealings 2 passes sequentially through the first connector 5, the first oil return pipe 6, the second connector 7, concentrates 8 and of oil return pipe
Second oil return pipe 9 reflux fuel tank 11.
Leakage hydraulic oil in the present embodiment is using gravitional force reflux fuel tank, and energy-saving, free from environmental pollution, repetition makes
With oil is not influenced, the cost of hydraulic oil is saved.The present embodiment needs detergent line repeatedly after installation, hydraulic to guarantee
The oil of oil.
The above is only the preferred feasible embodiment of the utility model, not thereby limits to the power of the utility model
Sharp range, it is all with the variation of equivalent structure made by the utility model specification and accompanying drawing content, it is both contained in the utility model
Interest field within.
