stacker cylinder Sold to France

This article mainly introduces:

France hydraulic cylinder,stacker cylinder manufacturer,stacker cylinder

(France stacker cylinder,produced by Hebei Hengyu company）

stacker cylinder are widely used in France，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed stacker cylinder for customers from France.

Introduction to stacker cylinder:

The material, shape and compression of the stacker cylinder seal have a great impact on the service life and work efficiency of the stacker cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

When installing the stacker cylinder, the axial ends of the stacker cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the stacker cylinder, there is axial expansion. If the two ends of the stacker cylinder are fixed, all parts of the stacker cylinder will be deformed. When disassembling the stacker cylinder, it is strictly forbidden to hammer the stacker cylinder and the piston surface, such as the stacker cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

stacker cylinder installation precautions: Before installing the stacker cylinder into the system, the parameters on the stacker cylinder label should be compared with the parameters when ordering. The base of the stacker cylinder must have sufficient stiffness, otherwise the stacker cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

The "O" ring can be used as an auxiliary seal inside the stacker cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the stacker cylinder, and can be completely sealed.

Answers to some questions about stacker cylinder:

Is there a national standard for the testing of hydraulic cylinders?
Generally speaking, the cylinder test is carried out according to JB/JQ20302 Allowable leakage of cylinder in pre-factory leakage test. GB2879 hydraulic cylinder piston and piston rod dynamic seal groove type, size and tolerance. GB6578 hydraulic cylinder piston rod dust ring groove type, size and tolerance. GB7938 hydraulic cylinder and cylinder nominal pressure series, etc.

What is the bearing capacity of the HOB cylinder?
The normal specification of HOB is 140 kg pressure, which is more commonly used in the market, and there are clear marks on the cylinder, 210 kg is a strengthened version of HOB, generally customized cylinders are also clearly marked on the above, when the specific use of the cylinder, the maximum use pressure is marked on the cylinder.
