Abstract
The utility model relates to a hydraulic cylinder, in particular to a diaphragm cavity-sharing double hydraulic cylinder, which is characterized in that two hydraulic cylinders are arranged in the same cavity, two hydraulic cylinder bodies are formed into a whole, and positions between the two hydraulic cylinders are often scoured by oil liquid, so corrosion, rusting or fracture and the like can be generated, grooves are formed at the middle lower parts and the bottom parts of the two hydraulic cylinders, diaphragms are embedded in the grooves, and then, sealing is carried out through sealing glue; the oil liquid scouring is avoided, so the phenomena such as corrosion, rusting or fracture can be avoided, and the service life can be prolonged.
Description
Technical field
The utility model relates to a kind of oil hydraulic cylinder, specially refers to a kind of barrier film with chamber double hydraulic cylinder.
Background technique
Hydraulic jack is suitable general the mechanically use of today, a lot of in particular cases all will using; Oil hydraulic cylinder by hydraulic energy change mechanical energy into, the do straight reciprocating motion hydraulic actuator of (or oscillating motion).Its simple in structure, reliable operation.While realizing to-and-fro motion with it, can remove speed reducer from, and there is no drive gap, motion steadily, is therefore used widely in the hydraulic system of various machineries.The pressure reduction on oil hydraulic cylinder ouput force and piston effective area and both sides thereof is directly proportional; Oil hydraulic cylinder is made up of cylinder barrel and cylinder cap, piston and piston rod, seal arrangement, damping device and venting gas appliance substantially.In reality is used, there is a kind of situation, need to remove to control two oil hydraulic cylinders by same set of hydraulic system, between two oil hydraulic cylinders of long duration, position is often subject to washing away of fluid, so can burn into get rusty or fracture etc., if fracture two oil hydraulic cylinders are connected, will affect the normal use of oil hydraulic cylinder.
Summary of the invention
The purpose of this utility model be to provide a kind of in use between two oil hydraulic cylinders position can not be subject to washing away of fluid, so can burn into get rusty or the situation such as fracture and then a kind of barrier film of normal use of affecting oil hydraulic cylinder with chamber double hydraulic cylinder.
To realize like this for realizing technique scheme the utility model, a kind of barrier film is with chamber double hydraulic cylinder, in same cavity, be provided with two oil hydraulic cylinders, described oil hydraulic cylinder comprises cylinder body and plunger rod composition, described plunger rod and cylinder body contacting point are provided with guide sleeve and seal ring, described cylinder body lower end and upper end are respectively equipped with filler opening and oil outlet, in the middle of described two cylinder lower, are provided with barrier film.
Describedly be provided with groove in two oil hydraulic cylinder middle and lower parts and bottom.
Described barrier film embeds in groove and uses sealant sealing.
Above-mentioned technological scheme is done further to analyze, and the utility model is provided with two oil hydraulic cylinders in same cavity; Two cylinder bodies are integrated, and between two oil hydraulic cylinders of long duration, position is often subject to washing away of fluid, so can burn into get rusty or fracture etc., so, the utility model is provided with groove in two oil hydraulic cylinder middle and lower parts and bottom, is embedded in barrier film at groove, then uses sealant sealing; Like this can not be subject to washing away of fluid, so burn into gets rusty or the generation of the phenomenon such as fracture, can increase the service life.
