Description
Technical field
The present invention relates to accumulator technical field, more particularly to a kind of large-scale lubricating oil station bladder type hydropneumatic accumulator.
Background technology
Accumulator is a kind of energy savings device in hydropneumatic system, it is in due course the energy in system
It is changed into compression energy or potential energy stores, is changed into the energy such as hydraulic pressure or air pressure when system needs, and by compression energy or potential energy
And discharge, feed system is mended again, and to ensure that whole system pressure is normal, accumulator can be divided into spring by load mode
Three kinds of formula, piston type and gas type, spring, piston type have seldom been used due to its limitation, and currently used is gas
Formula accumulator, gas type accumulator can be divided into pipe attenuator, gas-liquid direct-contact, piston type, diaphragm type, air bag by structure
Formula etc., bladder accumulator are the compressible character developments using gas (nitrogen), bladder accumulator by fluid part and
Gas part composition with seal, the fluid around leather bag are connected with fluid circuit, the fluid when pressure rise
Into accumulator, gas is compressed, and until system line pressures no longer rise, when loine pressure declines, compressed air expands,
Fluid is pressed into circuit, so that slow down the decline of loine pressure, such as patent " CN106368991A " discloses a kind of gasbag-type
Accumulator, including housing, inner cavity, air bag, bumper bracket, fluid control apparatus, liquid stream circulation device and groups of springs, the inside of housing
For inner cavity, and air bag is mounted with inner cavity, air bag is connected by air inlet pipe with connecting pin, and the lower end of inner cavity is provided with buffering
Frame, fluid control apparatus and liquid stream circulation device, the bladder accumulator combine the common bladder accumulator used now,
Branch process is carried out on the air feeder structure of adscititious gases, the structure of groups of springs is in addition used on the buffer structure of bottom and is set
Fluid control apparatus is put so that the pressure of inner cavity is reasonably controlled, and practicality is improved, such as patent
" CN204357794U " discloses a kind of helicitic texture bladder type hydropneumatic accumulator, including：Oily end end cap, housing and gas end end cap, oil
End end cap is connected with gas end end cap with housing by helicitic texture, and the first seal groove and the second sealing are provided with oily end end cap
Groove, the 3rd seal groove and the 4th seal groove are provided with the end cap of gas end, simple in structure after bladder type hydropneumatic accumulator uses some,
Common apparatus can realize producing in serial form；But the capacity of existing bladder type hydropneumatic accumulator is smaller, for large-scale lubricating oil station
Often volume is very big for the accumulator needed, can only be multiple by connecting when larger accumulator storage large energy is needed
The mode of accumulator uses, and such a occupation mode, not only the structure of accumulator is more complicated, and occupied space is bigger, and into
This is higher, and white elephant is caused to enterprise, while the structure of existing bladder type hydropneumatic accumulator is more complicated, using housing, gas
Capsule component, bacterial type valve and expanding plug etc. form, and the unlatching of accumulator is controlled by bacterial type valve, prevents air bag from deviating from, bacterial type
Valve easily cause during movement by the influence of external factor it is mobile dumb, while the edge of bacterial type valve than it is relatively thin
Leather bag is easily damaged during frequently being contacted with leather bag, influences the service life of airbag components, and then influence the work of accumulator
Make state.
The content of the invention
To overcome problems with existing in the prior art, the capacity of existing bladder type hydropneumatic accumulator is smaller, when large-scale profit
When lubricating oil station needs larger accumulator storage large energy, it can only be used, caused by way of connecting multiple accumulators
The structure of accumulator is more complicated, and occupied space is bigger, and cost is higher, while existing bladder type hydropneumatic accumulator structure ratio
More complicated, bacterial type valve easily causes during movement mobile dumb, while bacterial type valve by the influence of external factor
Edge is than the relatively thin service life damaged leather bag, influence airbag components easy during with the frequent contact of leather bag, Jin Erying
Ring the working status of accumulator.The present invention provides a kind of large-scale lubricating oil station bladder type hydropneumatic accumulator, including housing, balloon portion
Part, gas end device and oily end device, the gas end device are located at the upper end of housing, and the oil end device is located at the lower end of housing,

Occupied space is smaller, and the adaptability of space environment is good, avoid conventional cantilever formula installation space it is larger, easily topple over
Situation.
Its operation principle is：
The nitrogen of predetermined pressure is filled with leather bag component 2, when system pressure exceedes leather bag 2 internal pressure of component, fluid
Leather bag component 2 is compressed, the pressure in fluid is converted into the interior energy of gas in leather bag component 2；When system pressure is less than leather bag portion
During 2 internal pressure of part, leather bag component 2 expands, and promotes the fluid in housing 1 to flow to external system, releases energy, and maintains exterior system
Pressure of uniting and flow.
The structure uses spacing board-like structure, and relatively simple for structure, installation is easily serviced, in the gas to accumulator
While capsule component 2 carries out spacing, ensure that fluid flows between housing 1 and external system according to the differential flow of setting, keep away
Exempt from portable limiting device when system oil pressure changes, reaction is dumb, damages airbag components 2, influences the work shape of accumulator
State, while the volume of this kind of structure is big, volume scope can meet more than 1000L flows large-scale up to 300L~600L
Lubricating oil station uses, and multiple accumulators are used in combination the situation of systematic comparison complexity when avoiding big flow, and by protection department
Part and boom hoisting are fixed on the upper end of air inlet valve group, the security of lifting and the leakproofness of airbag components are ensure that, using branch
The mounting means of leg formula, makes bladder type hydropneumatic accumulator easier for installation, and the adaptability of space environment is good, avoids conventional cantilever formula peace
It is bigger to fill space, there is a situation where toppling over, reduces the occupied space of accumulator, reduces the use of accumulator
And maintenance cost.
