Design

Not only we could manufacture all kinds of heavy duty hydraulic cylinder on hydraulic press according to the drawing from customers,but also we could make a design according to customers'requirements. If you require our engineer to make a design, please advise us thefollowing 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 .
 

Manufacturing capability and cylinder size range

Max bore diameter: Ø1200mm
Max stroke: 12Meter
Max text pressure: 50MPa
 

Detailed Images

1.Cylinder tube

According to the cylinder pressure and inside diameter size, different steel tube Would be choosed.
ID ≤300mm, choose cold rolled precision seamless tube
300mm≤ID ≤500mm, choose hot rolled seamless tube
500mm≤ID ≤1000mm, choose forged tube
Steel grade : SAE1020, SAE1045, 27SiMn , S355JR, S355J2G3, St52-3, SUS304, SUS316L etc .
Inside boring and honing , roughness R0.2-R0.3
Inside chromating : if necessary ,tube inside chromating could be applied 


2Piston rod

steel grade : SAE1045, 42CrMo4, SUS410 ,SUS420, SUS304, SUS316L

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.

 

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.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.

 

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 testingpressure 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.
