(Ireland stacker cylinder,produced by Hebei Hengyu company）

stacker cylinder are widely used in Ireland，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed stacker cylinder for customers from Ireland.

Introduction to stacker cylinder:

Disassembly stacker cylinder: When disassembly stacker cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the stacker cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the stacker cylinder.

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.

After chrome plating of the piston rod of the stacker cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

In the process of using the stacker cylinder, sometimes such a problem will occur, the stacker cylinder can not act immediately after the instruction of the stacker cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil stacker cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

Answers to some questions about stacker cylinder:

Why is there noise in the hydraulic cylinder of the excavator lift arm?
There is no noise of a normal cylinder, check whether the throttle is ringing, or the mechanical part connected with it is ringing, and the mechanical part can be greased. If it can't be ruled out, disconnect the cylinder from the mechanical part and act alone to see what the situation is.

How to calculate the tonnage of the hydraulic press without konowing the diameter of the cylinder?
To know the tonnage of the hydraulic cylinder, you first need to know the working pressure of the hydraulic system, the inner diameter of the hydraulic cylinder and the outer diameter of the cylinder rod (the outer diameter of the cylinder rod is needed when calculating the hydraulic cylinder tension). The thrust of the hydraulic cylinder (that is, the force that the hydraulic cylinder can produce by extending out) = the cross-sectional area of the hydraulic cylinder (or the cross-sectional area of the piston) × the working pressure of the cylinder (the cross-sectional area of the piston) =pi*D^2/4= PI (take 3.14) × the square of the cross-sectional area of the piston ÷4 working pressure to see the pressure displayed on the pressure gauge when the maximum load is working.
