Abstract
Disclosed is a diaphragm type hydraulic accumulator. An upper shell (2) and a lower shell (6) are semi-spherical, cavities are arranged in the upper shell (2) and the lower shell (6), an oil inlet (1) and an air inlet (7) are respectively arranged at bottoms of the upper shell (2) and the lower shell (6), the middle of an isolating sac (4) is projected, the middle of the isolating sac (4) is jacked into the inner cavity of the upper shell (2) along the projecting direction, and openings of the upper shell (2) and the lower shell (6) are jointed oppositely. The upper shell and the lower shell are fastened to form a closed tank which is a hydraulic buffer, the hydraulic buffer is used for storage and compensation of energy in a hydraulic work system, and the elastic isolating sac and the lower shell form a closed cavity with liquid energy storage and supplementary functions. The diaphragm type hydraulic accumulator has the advantages of reasonable and compact structure, safe and reliable work, convenience in use and maintenance and high durability, and can be widely used for hydraulic systems in mechanical fields of wind power generation, petroleum, mines, hoisting and the like.
Description
Technical field
The utility model relates to the pressure functional component accumulator in a kind of international classifiation F15B general fluid work system, fluid pressure actuator or hydrodynamic pressure component technology field, the especially hydraulic equipment.
Background technique
In the known technology, accumulator is a kind of energy savings device in the hydropneumatic system.It is in due course and changes the energy in the system into the compression energy or potential energy stores, and when system needs, will compress energy or potential energy again and change energy such as hydraulic pressure or air pressure into and discharge, and mends supply system again.When system's instantaneous pressure increased, it can absorb the energy of this part.Guarantee that whole system pressure is normal.For example, application number: 91,201,271 1 kinds of hydraulic accumulators, comprise upper and lower casing, isolate capsule, nut etc., the joining portion that it is characterized in that hemispheric upper and lower casing is shaped on groove and withholds the convex opening edge that a hemisphere is isolated capsule, isolate the top of capsule and put a knob mouth shape helmet, its ring convex edge of housing of staying of linking closely at end when the screw thread of screw collar and upper shell outer rim spins, the top of upper and lower casing respectively is shaped on a screw.Known accumulator mainly is to have the shell of a sealing and an isolating film to constitute, and often because of isolating film rapid wear and the non-removable reason of shell, and can't repair in the use.
But, in disclosed correlation technique, do not find the concisely relevant improvement technology of structure as yet.
Summary of the invention
The purpose of this utility model provides a kind of tanning device with adjusting hydraulic system pressure of capsule formula structure, i.e. diaphragm type hydraulic accumulator.
Realize that the measure of the present utility model purpose comprises: the hemispherical of cavity arranged in upper casing and lower casing all are, upper casing and lower casing bottom each perforate respectively are filler opening and suction port, isolate capsule middle part projection, isolate capsule 4 middle part protrusion direction and head into the upper casing inner chamber, upper casing and the relative bonding of lower casing opening part.
Advantage of the present utility model is: upper casing and lower casing fasten and constitute closed tank, be hydraulic bjuffer, be used for the storage or saving and the compensation of hydraulic work system energy, elastomeric isolation capsule and lower casing constitute the enclosed cavity of hold concurrently a storage or saving and an additional liquid energy, have the convenient and high characteristics of durability of rational in infrastructure, compact, safe and reliable, working service, can be widely used in mechanical field hydraulic systems such as wind-power electricity generation, oil, mine, lifting.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Reference character: filler opening 1, upper casing 2, helmet 3 is isolated capsule 4, flange 5, lower casing 6, suction port 7.
Embodiment
Below in conjunction with specific embodiment, describe:
In upper casing 2 and lower casing 6 all are the hemispherical of cavity arranged, upper casing 2 and lower casing 6 bottoms each perforate respectively are filler opening 1 and suction port 7, isolate capsule 4 middle part projectioies, isolate capsule 4 middle part protrusion direction and head into upper casing 2 inner chambers, upper casing 2 and lower casing 6 opening part relative bondings.
Isolate helmet 3 is installed on the capsule 4 middle part projectioies.Helmet 3 effects are, when isolation capsule 4 is with buffering or liner to upper casing 2 or lower casing 6 inner bottom parts, with the projection of protection isolation capsule 4, reduce isolation capsule 4 and cause condition in damaged because of frequent impact.
Form spherical jar after upper casing 2 and the lower casing 6 opening part relative bondings.
Isolating capsule 4 diaphragm type elastic materials makes.
Isolating capsule 4 outer rims has circular protrusion, slots on corresponding upper casing 2 and the lower casing 6 opening part surfaces.Isolate capsule 4 outer rim circular protrusions, snap in corresponding upper casing 2 and lower casing 6 opening parts surface fluting.After the installation, can locate and compress.
The utility model embodiment charges into pressurized gas and sealing by lower casing 6 bottom air inlets 7, will install and insert hydraulic system; When hydraulic pressure in the system during greater than setting value, space between liquid stream injects in isolation capsule 4 tops and the upper casing 2 from filler opening 1, to isolate capsule 4 depresses, and with the space between pressure is in isolating capsule 4 bottoms and lower casing 6, pressurized gas, when system pressure reduces, lower casing 6 inner high voltage gases will be isolated capsule 4 and be ejected space in the extruding upper casing 2, and the press juice body medium is with compensatory pressure.
The utility model embodiment rated pressure 18MP, operating air pressure precompressed value 5MP, volume 1260cm
3, suction port M28 * 1.5, filler opening M18 * 1.5, the long 180mm of tank body, tank body maximum diameter 161mm, gross weight 8.5kg in the hydraulic transmission of intermittence, short-term operation, can reduce oil pump power, saves power.
In above embodiment, do not reach the technology such as manufacturing, installation and operation of narration, and the employing prior aries such as other necessary technologies that relate to enforcement, enumerate detailed description no longer successively.
