Attention
The accumulator or air compressor can't be shipped by air recently, here are two methods to ship
1)Shipped by sea,buy accumulators or air Compressor mixed with other products at
least 0.5cbm
delivery time is around 30- 35 days
sea freight is 50-100$ per cbm
2)Through your country's agents in China,can pay RMB or USD(paypal)
Any confuse,please contact us on line
CAUTION
only nitrogen is permitted for the accumulator . Oxygen ,
compressed air , combustibe/exposive gas and other unknow gas shall be strictly
prohibited for the explosion risk.
Principle of Accumulator
Accumulator is a hydraulic accessory designed to accumulate the
pressured liquid . Fluids are practically incompressible and cannot
therefore store pressure energy . In hydraulic accumulators the
compressibility of gas is utilized for storing fluids . The
accumulator draws in fluid when the pressure increases and the gas
are compressed . When the pressure drops , the compressed gas
expands and forces the stored fluids into the circuit
Use of Accumulator
1.Energy Storage
Accumulator is widely used in the auxiliary energy . It accumulates
the oil intermittently outputted by pump while releases fluid more
than the pump flux . Therefore , The accumulator helps the pump to
be size – miniaturization and energy – saving .
2.Pulsation Absorption
Accumulator absorbs pulsation created by pressure fluid that is
released by various pump to protect the pipe from the infection of
pressure , noise and vibration .
3.Impact Absorption ( Decrease )
In hydraulic circuit , impact in the pipe caused by rapid switching
or sudden changing of load bring noise and pipe damage .
Accumulator is set to absorb ( Decrease ) The impact
4.Leakage Compensation
In pressure control circuit and condition of pressure maintaining ,
accumulator is set to maintain the pressure by compensating the
pressure reduction caused by internal and external leakage .
5.Volume Compensation
In closed circuit , internal pressure changes because variety in
temperature results in variety of liquid volume . The accumulator
reduces the change of pressure to protect valves . gaskets and
pressure gauge from failure
6.Vibration Absorption
The accumulator absorbs the mechanical vibration for the gas in the
accumulator works as spring to reduce the impact and vibration of
vehicle .
7.Balance
The accumulator can be used as balance for the gas pressure in
accumulator stably balances the weight of product and machine and
impact .
8.Fluid separation
The accumulator generally separated the two medium ( Hydraulic
purpose : nitrogen and oil ). However , the accumulator canbe also
used to transmit pressure between two liquid which can be mixed
Mounting Position
Accumulators can be installed vertically,horizontally and
obliquely. When vertically or obliquely installed,the oil valve
must be at the bottom. In case of
the application listed below,particular positions are recommended.
1. Type of Mounting
Accumulators which volume is less than 1L,can be installed directly
in the pipeline. For Strong Vibration
and volumes above 1L,fixed with bracket or accumulator mounting
sets are recommended
2. Charging Nitrogen
Nitrogen must be charged into the bladder before the accumulator
starts to work. Charging nitrogen must use
charging tools-CQJ type charging tool. If nitrogen pressure does
not meet the requirement of accumulator.
Please use chaori CDZ type nitrogen filling vehicle.
3. Caution
Do not have welding or mechanical processing work on the
accumulator shell:Only nitrogen are allowed. Use
of Oxygen ,combustibie or corrosive gases is strictly prohibited.
Accumulators should be mounted in the hydraulic
Systems which have overflow valves or safety valves.
