large long cylinder are widely used in Algeria，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed large long cylinder for customers from Algeria.

Introduction to large long cylinder:

The material of the sliding part of the large long cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

There are some honeycomb holes in the inner wall of the large long cylinder, piston or piston rod surface. How is this formed? When we repair the large long cylinder, we can see that there are some honeycomb holes on the inner wall of the large long cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the large long cylinder is targeted to prevent. Is very necessary.

When installing the large long cylinder, the axial ends of the large long cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the large long cylinder, there is axial expansion. If the two ends of the large long cylinder are fixed, all parts of the large long cylinder will be deformed. When disassembling the large long cylinder, it is strictly forbidden to hammer the large long cylinder and the piston surface, such as the large long 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.

How to repair the large long cylinder body when it is damaged: When the large long cylinder has trace deformation and shallow tensile marks, the large long cylinder is repaired by strong honing process. The heavy honing process can repair large long cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the large long cylinder can meet the technical requirements.

Answers to some questions about large long cylinder:

Why are the hydraulic cylinders out of sync? The reasons for the unsynchronous operation are as follows: 1, the deviation of the external load of the two cylinders, such as the different resistance and friction of the two cylinders will lead to imbalance. The displacement of the cylinder with low resistance will be larger. 2, the difference in internal friction, such as the difference between the piston and the cylinder of each cylinder, the friction between the piston rod and the seal causes the cylinder to be out of sync. 3. The different resistance of hydraulic oil along the pipeline of the two cylinders causes the cylinder to be out of sync. 4, the deviation of the control original adjustment causes the deviation of the flow to be out of sync, such as the use of an independent throttle valve for each cylinder will appear the difference in the flow of oil in and out of the oil affecting the synchronization of the two cylinders. 5. The cylinder support point of the supported part is initially different.

Hydraulic cylinder load algorithm?
If it is thrust, load = working pressure x piston area. If it is pulling force, load = working pressure x(piston area - piston rod area).
