Abstract
The invention discloses a water cooling type hydraulic oil cylinder which comprises a cylinder body, a piston, a piston rod, a cylinder head and a cylinder tail. The piston and the piston rod are arranged in the cylinder body. The piston is fixedly connected with the piston rod, and the cylinder head and the cylinder tail are respectively fixed at two ends of the cylinder body. A water cooling tank is arranged outside the cylinder body in sealing mode, and the cylinder tail is provided with a deflating valve communicated with the inside of the cylinder body. The water cooling type hydraulic oil cylinder greatly reduces oil cylinder temperature in the processing process due to the fact that the water cooling tank is arranged outside the cylinder body in sealing mode, prevents heat deformation and prolongs service life. Simultaneously, air in the cylinder body can be discharged due to the fact that the deflating valve is arranged at the cylinder tail, and effects on working performance of the oil cylinder can be prevented.
Description
Technical field
The present invention relates to a kind of water-cooling type hydraulic jack.
Background technique
Hydraulic jack with hydraulic pressure can change mechanical energy into, the do straight reciprocating motion hydraulic actuator of (or oscillating motion).When realizing to-and-fro motion with it, can remove speed reducer from, and not have drive gap, therefore motion steadily is used widely in the hydraulic system of various machineries.
Hydraulic jack is when long-term work, and the oil cylinder temperature is higher, is easy to generate thermal distortion, influences the operating life of oil cylinder, simultaneously, in the general oil cylinder air is arranged, and the air in the cylinder body is sneaked into the service behaviour that can influence hydraulic system in the hydraulic oil.
Summary of the invention
The technical problem that the present invention mainly solves provide a kind of simple in structure, be connected firmly, good cooling results, can discharge the water-cooling type hydraulic jack of air in the cylinder body.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of water-cooling type hydraulic jack is provided, comprises cylinder body, piston, piston rod, cylinder head and cylinder tail; Said piston, piston rod are arranged in the cylinder body; Piston is fixedly connected with piston rod, and said cylinder head, cylinder tail are separately fixed at the cylinder body two ends, and said cylinder body external sealed is provided with the water-cooled case; Said cylinder tail is provided with bleed valve, and said bleed valve is communicated with inner chamber of cylinder block.
In preferred embodiment of the present invention, be provided with filter screen in the said bleed valve.
In preferred embodiment of the present invention, said cylinder head, cylinder tail are connected with cylinder body through fixed plate.
In preferred embodiment of the present invention, be provided with some seal rings between said cylinder body and cylinder head, the cylinder tail.
The invention has the beneficial effects as follows: water-cooling type hydraulic jack of the present invention is owing to be provided with the water-cooled case at the cylinder body external sealed; In course of working, greatly reduce the temperature of oil cylinder, prevent to produce thermal distortion, improved the operating life of oil cylinder; Simultaneously; Owing to bleed valve is set at the cylinder tail, can discharge the air in the cylinder body, prevent to influence the service behaviour of oil cylinder.
Description of drawings
Fig. 1 is the perspective view of water-cooling type hydraulic jack one preferred embodiment of the present invention;
The mark of each parts is following in the accompanying drawing: 1, cylinder body, 2, piston, 3, piston rod, 4, cylinder head, 5, the cylinder tail, 6, the water-cooled case, 7, bleed valve, 8, fixed plate.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises:
A kind of water-cooling type hydraulic jack; Comprise cylinder body 1, piston 2, piston rod 3, cylinder head 4 and cylinder tail 5, said piston 2, piston rod 3 are arranged in the cylinder body 1, and piston 2 is fixedly connected with piston rod 3; Said cylinder head 4, cylinder tail 5 are separately fixed at cylinder body 1 two ends; Said cylinder body 1 external sealed is provided with water-cooled case 6, and said cylinder tail 5 is provided with bleed valve 7, and said bleed valve 7 is communicated with cylinder body 1 inner chamber.
Be provided with filter screen in the said bleed valve 7, can prevent that introduced contaminants from passing through bleed valve 7 and getting in the cylinder body 1, prevent that hydraulic oil is contaminated.
Said cylinder head 4, cylinder tail 5 are connected easy installation and removal, fixation through fixed plate 8 with cylinder body 1.
Be provided with some seal rings between said cylinder body 1 and cylinder head 4, the cylinder tail 5, can prevent that condensed water from getting in the cylinder body 1, sealing effect is better.
Add man-hour, open bleed valve 7, can in-oil cylinder air be emitted, simultaneously, the water in the water-cooled case 6 can reduce the temperature of cylinder body 1, thereby has improved the processibility of this hydraulic jack.
Compared with prior art, water-cooling type hydraulic jack of the present invention greatly reduces the temperature of oil cylinder owing to be provided with water-cooled case 6 at cylinder body 1 external sealed in course of working; Prevent to produce thermal distortion; Improved the operating life of oil cylinder, simultaneously, owing to bleed valve 7 is set at cylinder tail 5; Can discharge the air in the cylinder body 1, prevent to influence the service behaviour of oil cylinder.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
