Accumulator manufacturer -- Nakamura Koki Co., Ltd. | Technical information

 

Appropriate accumulators should be selected depending on various factors such as intended use, service conditions, location, etc.

 Which accumulator type is better, bladder type or piston type?

 What is the appropriate rubber material?

 What size should be selected?

 etc.

Main elements for accumulator selection are listed as follows:

 

1.What is the intended use?

1) Energy storage or power compensation

2) Pulsation dampener for a piston pump, etc.

3) Water-hammer/surge-pressure absorption (shock absorption)

4) Temperature change compensation for an hydraulic line

5) Leak compensation / pressure compensation for pressurized liquid circuits

6) Vehicle suspension

7) Others (What is your demand to the accumulator?)

 

2. What are the service conditions?

1) Discharge volume of fluid

2) Maximum and minimum working pressure

3) Maximum and minimum working temperatures

4) Discharge (maximum discharge rate) and storage time of fluid

5) Pump specifications(for pulsation absorption)

6) Fluid type

7) Hydraulic piping system specification(for shock absorption / temperature compensation)

8) Activation frequency?

 

3. Place and environment

1) Installation site
Japan, (Industrial complex?), Country other than Japan? (Country name?)

2) Indoor or outdoor

3) Corrosive environment or not

4) Is the place convenient for easy maintenance?

5) Are there limitations for installation space?

6) Mounted on a ship? (Subject to classification survey?)

7) What kind of equipment is it? (Social importance of the equipment?)

8) Is the equipment under any laws and regulations other than the High Pressure Gas Safety Act in Japan?

 

4. Other information

1) Do you have experience in using accumulators?

2) Have there been any troubles in using an accumulator in the past?

3) Do you need an accumulator only or an accumulators stand?

 

We recommend the best accumulator for your intended use based on above information.

Please contact our sales office (international sales: nak-int@hyd-acc.co.jp).

Furthermore, you can also select the accumulator size (capacity) by yourself by using "Technical calculation of accumulator capacity" provided in our catalogue.
