Description
Technical field
The utility model belongs to technical field of hydraulic pressure, particularly relates to a kind of barrier film bladder type hydropneumatic accumulator.
Background technique
Accumulator is a kind of energy savings device in hydropneumatic system, it is in due course the energy conversion in system is that compression energy or potential energy store, when system needs, again compression energy or potential energy changed into the energy such as hydraulic pressure or air pressure and discharge, again supply system is mended, when system instantaneous pressure increases, it can absorb this part energy, ensures that whole system pressure is normal.Accumulator has two kinds of purposes: the flow that load needs when low-speed motion is less than oil hydraulic pump flow, and the unnecessary flow of oil hydraulic pump stores up into accumulator, and when loading demands flow is greater than oil hydraulic pump flow, liquid is released from accumulator, with the deficiency of fluid infusion press pump flow; When shutdown but still when need maintain certain pressure, can stop solution press pump and by the leakage of accumulator bucking-out system, with the pressure of keeping system.Accumulator also can be used to the hydraulic shock pressure produced in the pressure pulsation of absorption liquid press pump or absorption system.
Bladder type hydropneumatic accumulator installs a bag-shaped capsule in the inside of accumulator as gas-liquid isolated component, with the capsule of entirety by air cavity airtight for the air chamber of accumulator.Existing bladder type hydropneumatic accumulator, complex structure, capsule quality is large, slow to liquid fluctuation reflection, can not Absorbing Fluctuation effectively.
Diaphragm accumulator assembles a diaphragm between upper-lower casing, and be closed by air cavity by the way of sealing by the housing of supporting ring by barrier film and accumulator, this structure, by the impact at sealing position, can cause seepage.The accumulator volume of existing diaphragm type is little, is generally less than 10L.
Have a kind of welding diaphragm type accumulation of energy housing to adopt lap-welded structure abroad, its working pressure is low, and this patent product upper-lower casing adopts butt welding, can improve the pressure of product.Volume can be accomplished to be greater than 10L.This patent product, lightweight, pressure is large, and compression ratio is high.
Summary of the invention
The utility model provides a kind of barrier film bladder type hydropneumatic accumulator, and propose existing bladder type hydropneumatic accumulator to solve in above-mentioned background technology, pressure-bearing pressure is little; The problems such as existing diaphragm accumulator hydraulic fluid port seepage.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of barrier film bladder type hydropneumatic accumulator, it is characterized in that: comprise upper shell, lower shell body, barrier film, described upper shell is positioned at the top of lower shell body, and link up formation main weld by welded joint and lower shell body, the underpart of described lower shell body is provided with hydraulic fluid port, the upper end portion of described upper shell is provided with gas port, described barrier film is positioned at lower shell body, its inside is provided with support ring, described support ring connecting welding joint, can be used as the backing plate connecing welded joint, accumulator nitrogen chamber is formed between described upper shell and barrier film.
By being welded to connect between described hydraulic fluid port and lower shell body.
By being welded to connect between described gas port and upper shell.
The distance of 6 times of weld seams is provided with between described support ring and main weld.
Described barrier film becomes a complete rubber part with supporting ring forming die swaging.
The beneficial effects of the utility model are:
1 this patent adopts the technological scheme by forming air cavity at upper shell and diaphragm support ring, makes accumulator have good tightness.
2 this patents are provided with 6 times of distance between the toes of a weld by between the metal support ring of barrier film and main weld, are unlikely to barrier film scaling loss like this when welding, and therefore also welding procedure and equipment is less demanding, has good manufacturability.
3 this patents simplify the structure of the hydraulic fluid port of bladder type hydropneumatic accumulator, improve the shortcoming of bladder type hydropneumatic accumulator hydraulic fluid port seepage.Because the quality of barrier film is light, the reaction of accumulator is sensitiveer, and the compression ratio of accumulator can reach 1:8.
The volume of 4 this patent accumulators can be greater than 10L, and pressure is high, lightweight, compact structure.
The accumulator of 5 this patents has the advantage of both bladder type hydropneumatic accumulator and diaphragm accumulator concurrently, the capacious advantage of accumulator of existing bellows, and the tightness of air cavity, have again the structure of diaphragm accumulator simple, be quick on the draw, advantage that compression ratio is high.
6 this patents are using the backing plate of supporting ring as welding, and upper-lower casing adopts butt joint, and chooses higher welded joint coefficient, and the pressure-bearing pressure of accumulator is improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
In figure: 1-upper shell, 2-lower shell body, 3-barrier film, 4-hydraulic fluid port, 5-gas port, 6-welded joint, 7-support ring, 8-accumulator nitrogen chamber.
Embodiment:
The present embodiment comprises upper shell 1, lower shell body 2, barrier film 3, upper shell 1 is positioned at the top of lower shell body 2, and link up formation main weld by welded joint 6 and lower shell body 2, the underpart of lower shell body 2 is provided with hydraulic fluid port 4, and the upper end portion of upper shell 1 is provided with gas port 5, and barrier film 3 is positioned at lower casing 2 body, its inside is provided with support ring 7, support ring 7 connecting welding joint 6, can be used as the backing plate connecing welded joint 6, forms accumulator nitrogen chamber 8 between upper shell 1 and barrier film 3.
Utilize technological scheme described in the utility model, or those skilled in the art being under the inspiration of technical solutions of the utility model, designing similar technological scheme, and reach above-mentioned technique effect, is all fall into protection domain of the present utility model.
