Description
Technical field
The utility model relates to a kind of oil cylinder with seal ring, belongs to mechanical-hydraulic technical field.
Background technique
In hoist technical field, hydraulic system so that its volume is little, lightweight, movement inertia is little, stable movement, long service life, can the advantage such as large-scale stepless speed governing, be more and more employed.Oil cylinder is a core component in hydraulic system, and its function is that hydraulic energy is converted to mechanical energy.Mainly there is following defect in existing structure:
(1), the easy leakage of oil of oil cylinder;
(2), Security is poor, causes accident.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of oil cylinder with seal ring, have and prevent leakage of oil, safe and reliable advantage.
The technical solution of the utility model is: a kind of oil cylinder with seal ring, comprise Master cylinder body, it is characterized in that: at the fore-end of Master cylinder body, the inwall of Master cylinder body matches with main plunger, terminal before main plunger, at Master cylinder body front end outer wall, adapter is installed, there is copper packing adapter below, adapter two side is provided with pressure ring, pass through pressure ring, screw is followed closely, adapter is fixed on Master cylinder body by copper packing, one section, the centre of Master cylinder body, main plunger outer ring is provided with a circle silicon carbide seal ring, after silicon carbide seal ring, main plunger outer ring is provided with one-level clamping sleeve, in the rear of one-level clamping sleeve terminal, main plunger outer ring is provided with a circle nitrile butadiene rubber seal ring, after nitrile butadiene rubber seal ring, main plunger outer ring is provided with secondary clamping sleeve, match with Master cylinder body in secondary clamping sleeve outer ring, secondary clamping sleeve stretches out the position of Master cylinder body, its outer ring is provided with pressing plate, pressing plate is fixed with Master cylinder body by screw nail.
The beneficial effects of the utility model are: a kind of oil cylinder with seal ring disclosed in the utility model, has and prevent leakage of oil, safe and reliable advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of I part in Fig. 1.
In Fig. 1, Fig. 2,1. screw nail, 2. copper packing, 3. takes over, 4. pressure ring, 5. Master cylinder body, 6. main plunger, 7. silicon carbide seal ring, 8. one-level clamping sleeve, 9. nitrile butadiene rubber seal ring, 10. secondary clamping sleeve, 11. pressing plates, 12. screw nails.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As Fig. 1, shown in Fig. 2, the utility model is a kind of oil cylinder with seal ring, comprise Master cylinder body 5, it is characterized in that: at the fore-end of Master cylinder body 5, the inwall of Master cylinder body 5 matches with main plunger 6, terminal before main plunger 6, at Master cylinder body 5 front end outer wall, adapter 3 is installed, copper packing 2 is had below adapter 3, adapter 3 two side is provided with pressure ring 4, by pressure ring 4, screw nail 1, adapter 3 is fixed on Master cylinder body 5 by copper packing 2, one section, the centre of Master cylinder body 5, main plunger 6 outer ring is provided with a circle silicon carbide seal ring 7, after silicon carbide seal ring 7, main plunger 6 outer ring is provided with one-level clamping sleeve 8, in the rear of one-level clamping sleeve 8 terminal, main plunger 6 outer ring is provided with a circle nitrile butadiene rubber seal ring 9, after nitrile butadiene rubber seal ring 9, main plunger 6 outer ring is provided with secondary clamping sleeve 10, match with Master cylinder body 5 in secondary clamping sleeve 10 outer ring, secondary clamping sleeve 10 stretches out the position of Master cylinder body 5, secondary clamping sleeve 10 outer ring is provided with pressing plate 11, pressing plate 11 is fixed by screw nail 12 and Master cylinder body 5.
The utility model in use; from the lubricant oil that adapter 3 enters; flow to main plunger 2 and Master cylinder body 1 contacting point; owing to being provided with silicon carbide seal ring 7, nitrile butadiene rubber seal ring 9; and silicon carbide seal ring 7 compresses by one-level clamping sleeve 8; nitrile butadiene rubber seal ring 9 compresses by secondary clamping sleeve 10, is played the effect preventing leakage of oil by second class protection, improves the Security that oil cylinder uses.
As can be seen here, the utility model has and prevents leakage of oil, safe and reliable advantage.
