large cylinder are widely used in Colombia，because of long service life，smooth movement，high work efficiency.So our company has designed large cylinder for customers from Colombia.

Introduction to large cylinder:

If it is found that the large cylinder lubrication is poor or the large cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the large cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the large cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the large cylinder center line. In this way, when the piston works in the large cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the large cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

If the large cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

Improve the service life of the large cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the large cylinder (such as the large cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the large cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the large cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single large cylinder exhaust.

The repair method of the large cylinder: the repair of the large cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.

Answers to some questions about large cylinder:

What is the relationship between medium cylinder and side cylinder ratio of forklift truck?
The middle cylinder and the side cylinder seem to have no relationship, as long as the lifting speed required by the design can be ensured, but the diameter of the cylinder can not be too thin, so as to avoid the middle cylinder acting first when the high gantry vibration lifting, and then the two cylinders acting again.

How to select swing cylinder? Under what conditions are they designed and selected?
1, determine the system parameters: ① the weight and the required force; ② Nominal working pressure and range; ③ The time required to travel this distance; 4 oil medium 2, installation method: select the appropriate way for the specific application 3, cylinder diameter and working pressure: determine the cylinder diameter and provide the necessary force required by the system pressure 4, piston rod: determine the minimum piston rod diameter required to withstand the longitudinal bending force, select the appropriate piston rod end and piston rod end thread 5, piston: Whether the seal type is suitable for the application 6, buffer: choose the buffer requirements as appropriate.
