Product Description

1.Main Description

 

ETERNAL company design and manufacture heavy duty hydraulic cylinders  that covering

the following fields:

 

Ø hydraulic press cylinder

Ø construction machinery cylinder

Ø mining machinery cylinder

Ø metallurgy machinery cylinder

Ø water power project cylinder

Ø marine hydraulic cylinder

Ø servo hydraulic cylinder

 

 

2. Design 

 

Not only we could manufacture all kinds of hydraulic cylinders according to the drawing from our

customers,but also we could make a design according to customer's requirements.If you 

require our engineer to make a design,pls advise us the following specification:

 

1. Rated pressure 

2. Working pressure 

3. Test pressure 

4. Working condition and environment ,for example ,temperature ,working frequency 

5. Pulling force ,and return stroke force

6. Pulling and return speed 

7. Assembly size  

8. Seal ring requirements .For example , brand ,seal material etc .

9. Tube and piston rod raw material requirements 

10. Piston rod surface treatment requirements, for example chromating film thickness ,   

 Surface hardness etc . 

11. Painting and other spare parts requirements .

 

 

3. Manufacturing capability and cylinder size range 

 

3.1 Cylinder bore diameter :max Ø1200mm 

3.2  Cylinder length :10Meter 

3.3  Max lifting capability :50 Tons 

 

 

4.Manufacturing and inspection 

 

4.1.Cylinder tube size and choice  

 

4.1.1   According to the cylinder pressure and inside diameter size ,different steel tube Would be choosed .

 

1.  ID 300mm , cold rolled precision seamless tube would be choosed 

2.  300mm≤ID ≤500mm , hot rolled seamless tube would be choosed 

3.  500mm≤ID ≤1000mm, forged tube would be choosed 

 

4.1.2 Cylinder tube steel grade : SAE1020 , SAE1045 ,27SiMn , S355JR ,S355J2G3

St52-3 ,SUS304 ,SUS316L etc .  

4.1.3 Cylinder tube inside boring and honing , roughness R0.2-R0.3,

 

4.1.4 Cylinder tube inside chromating : if necessary ,tube inside chromating could be applied 

.

4.2  Piston rod  is a very important part for hydraulic cylinder .

 

4.2.1 Piston rod steel grade : SAE1045, 42CrMo4, SUS410 ,SUS420, SUS304, SUS316L 

 

4.2.2 Piston rod chromating and surface hardness .

        Eternal company ensure that every piece piston rod would be surface hardened before chromating ,

surface hardness is HRC55~60 , Chromating film thickness is 0.03~0.04mm if there is no other specific 

requirements .

 

4.3 Seal ring and O ring 

 

According to the customers' requirements and working condition , eternal company would choose suitable 

seal ring kit , seal ring brand include :Parker , Merkel , NOK , Guangzhou Rubber institute , Taiwan brand etc . Eternal company would supply suitable seal solution for their customer so that hydraulic cylinder has more

 lifetime , easy maintenance and simple repairing .

 

4.4 Tube and flange welding 

 

 The welding on cylinder tube and flange would be Ultrasonic tested every time , the welding seam would be 

cleaned before machining .Eternal company ensure that every welding seam has no any leak during lifetime 

 

4.5 Assembly and pressure test

 

Before hydraulic cylinder is assemblied , every spare parts would be measured and cleaned .After hydraulic

 cylinder is assemblied , pressure test would be carried out one By one , eternal company ensure that testing

 pressure is higher 30%-50% than working pressure  , and pressure holding time 30~60 minutes is necessary . Every piece hydraulic cylinder must be tested completely without any leak .

 

 4.6 Painting and storage .

 

After hydraulic cylinder pass through pressure test , painting is necessary .
