The invention provides a kind of corrosion-resistant hydraulic cylinder kind, including cylinder barrel, piston and piston rod, the piston rod surface sets at least one layer of anticorrosive coat, also include the driving pressure room on the left of piston and be arranged on the cylinder of the stainless steel protection filled with lubricating oil of cylinder barrel periphery, described stainless steel protection cylinder one end is connected with cylinder barrel outer side seal, the other end is tightly connected with being fixedly installed on the baffle liner of cylinder barrel front end, it is close on the inside of the baffle liner on the outside of piston rod, the ring-shaped groove slowly flowed for lubricating oil is provided with the baffle liner, some inclined pod apertures are provided between the driving pressure room and stainless steel protection cylinder.The present invention at utmost avoids the corrosion of piston rod using anticorrosive coat and the double safeguard procedures of lubrication, while the setting of stainless steel protection cylinder, while effectively cylinder barrel is protected, also provides oil circuit for the lubrication of piston rod.In a word, the present invention is simple in construction, and corrosion resistance is strong, can effectively extend the service life of hydraulic cylinder.
Description
Technical field
The present invention relates to a kind of hydraulic cylinder, particularly a kind of corrosion-resistant hydraulic cylinder.
Background technology
Existing hydraulic cylinder is mainly made up of cylinder barrel, piston, piston rod, guide sleeve, rear end cap and seal, due to existing
Hydraulic cylinder piston rod typically all without preservative treatment, piston rod can not enter under water, therefore be restricted using scope.This
Outside, existing hydraulic cylinder piston rod is in order to strengthen its decay resistance, if plating dried layer anticorrosive coat in its outer weekly assembly, although this
The corrosion of piston rod is avoided to a certain extent, but its corrosion resistance is influenceed larger by coating material, and corrosion-resistant timeliness is limited,
And existing hydraulic cylinder is inadequate for the protection of cylinder barrel, causes cylinder barrel perishable over time, this also have impact on hydraulic cylinder
Service life.
The content of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of corrosion-resistant hydraulic cylinder kind, existing product is solved
Corrosion resistance it is not strong and to cylinder barrel protection it is inadequate the problem of.
The technical solution adopted for the present invention to solve the technical problems is：A kind of corrosion-resistant hydraulic cylinder, including cylinder barrel, piston
And piston rod, at least one layer of anticorrosive coat of piston rod surface setting, it is characterised in that also including the driving pressure on the left of piston
Room and the cylinder of the stainless steel protection filled with lubricating oil for being arranged on cylinder barrel periphery, described stainless steel protection cylinder one end and cylinder barrel outside
It is tightly connected, the other end is tightly connected with being fixedly installed on the baffle liner of cylinder barrel front end, is close to piston rod on the inside of the baffle liner
The ring-shaped groove slowly flowed for lubricating oil, the driving pressure room and stainless steel protection are provided with outside, the baffle liner
Some inclined pod apertures are provided between cylinder.
The positive effect of the present invention：The present invention at utmost avoids piston using anticorrosive coat and the double safeguard procedures of lubrication
The corrosion of bar, while the setting of stainless steel protection cylinder, while effectively cylinder barrel is protected, is also provided for the lubrication of piston rod
Oil circuit, when oil pressure increases in driving pressure room, while promoting piston rod movement, tiny segment oil pressure is transmitted by pod apertures
To stainless steel protection cylinder, separator piston is slided slightly under oil pressure so that the lubricating oil in lubricating oil area is equal through ring-shaped groove
Even to be applied to piston rod outer surface, this further avoid piston rod and is contacted with air or the direct of other liquid, more great Cheng
The corrosion of piston rod is avoided on degree；In addition, three set safeguard procedures of the setting of oil cylinder protective case equivalent to hydraulic cylinder, can
Dust and corrosive liquids are effectively isolated, and can be changed at any time, the corrosion resistance to whole hydraulic cylinder provides strong guarantee.
In a word, the present invention is simple in construction, and corrosion resistance is strong, can effectively extend the service life of hydraulic cylinder.
Brief description of the drawings
Fig. 1 is a kind of structural representation of corrosion-resistant hydraulic cylinder of the present invention.
Embodiment
Below in conjunction with the accompanying drawings to a preferred embodiment of the present invention will be described in detail.
Reference picture 1, a kind of corrosion-resistant hydraulic cylinder of offer of the preferred embodiment of the present invention, including cylinder barrel 1, piston 2 and piston
Bar 3, the surface of piston rod 3 sets at least one layer of anticorrosive coat, it is characterised in that also include the driving pressure room 4 in the left side of piston 2
And be arranged on outside the cylinder of the stainless steel protection filled with lubricating oil 5 of the periphery of cylinder barrel 1, described stainless steel protection 5 one end of cylinder and cylinder barrel 1
Side seal is connected, and the other end is tightly connected with being fixedly installed on the baffle liner 6 of the front end of cylinder barrel 1, and the inner side of baffle liner 6 is close to live
Be provided with the ring-shaped groove 7 slowly flowed for lubricating oil on the outside of stopper rod 3, the baffle liner 6, the driving pressure room 4 with not
Some inclined pod apertures 8 are provided between rust steel protection cylinder 5.
It is preferred that, the inner side of 1 periphery stainless steel protection cylinder of cylinder barrel 5 is provided with two separator pistons 9, the separator piston
Stainless steel protection cylinder internal separation is lubricating oil area 10, transit buffer 11 and hydraulic oil area 12 by 9.
It is preferred that, the front end of piston rod 3 is provided with the outside of connecting rod, the connecting rod and is provided with first flange disk 13,
Second flange disk 14 is provided with the outside of the end of cylinder barrel 1, is provided between the first flange disk 13 and second flange disk 14
Oil cylinder protective case 15, the oil cylinder protective case 15 can form a sealing space in oil cylinder periphery, prevent in oil cylinder is run
There is thing to penetrate into and oil cylinder is damaged in oil cylinder, keep the clean and tidy of oil cylinder pull bar, it is ensured that the normal operation of oil cylinder.
It is preferred that, the lubricating oil area 10 of the stainless steel protection cylinder 5 is provided with tank filler sleeve.
When hydraulic cylinder elongation is acted, by being directed into the work oil liquid pressure of driving pressure room, piston and piston rod
Want to move left along cylinder barrel central axis, meanwhile, the wherein sub-fraction operating oil pressure in driving pressure room is transmitted by pod apertures
To stainless steel protection cylinder, and then promote the minute movement of separator piston so that the lubricating oil in lubricating oil area uniformly lubricates not
The disconnected piston rod stretched out, the effect one of separator piston is that lubricating oil is tried one's best with working oil to keep apart, and two are to try to avoid work
Make oily heat transfer to lubricating oil to ensure lubricant effect, the effect of transit buffer lies also in this.
Above-described is only the preferred embodiments of the present invention, and the explanation that should be understood that above example is to use
Understand the method and its core concept of the present invention in help, the protection domain being not intended to limit the present invention is all the present invention's
Any modification for being made within thought and principle, equivalent substitution etc., should be included in the scope of the protection.
