(Sri Lanka folding machine cylinder,produced by Hebei Hengyu company）

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

Introduction to folding machine cylinder:

Factors that should be considered when selecting the oil seal in the folding machine cylinder: some specific factors should be taken into account when selecting the oil seal in the folding machine cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: folding machine cylinder diameter, piston rod diameter, piston rod and piston groove size, folding machine cylinder working pressure, folding machine cylinder movement speed, hydraulic system oil temperature and folding machine cylinder working environment.

The internal leakage of the folding machine cylinder should be prevented when the folding machine cylinder is used. The internal leakage of folding machine cylinder includes the leakage caused by excessive wear of folding machine cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.

The folding machine cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the folding machine cylinder should pay attention to: the operation should be as far away from the folding machine cylinder as possible, to avoid falling objects, knocking, rubbing the folding machine cylinder coating. When cleaning the folding machine cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the folding machine cylinder when the oil temperature exceeds 70 ° C.

When the folding machine cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the folding machine cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the folding machine cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the folding machine cylinder can meet the requirements by grinding. However, the life and reliability of this repair folding machine cylinder are not high.

Answers to some questions about folding machine cylinder:

What welding rod is used for hydraulic cylinder welding?
There are several reasons for bad welding of hydraulic cylinder: 1. There is hydraulic oil on the welding surface, wipe it with a rag, there will be bubbles in the welding process, and it will not last for a few days. You have to remove it, drain it, wash it off with gasoline and try again. 2. Open the groove before welding, it is not deep enough to use the Angle grinding machine, and can not find the accurate crack position. 3. The material of the cylinder itself is not clear, the welding performance of more than 35 steel is not good, in the factory welding needs to preheat, the welding rod should also be dried and insulated, there is no such condition on the site.

What do cylinder internal leakage and external leakage mean?
Internal leakage means that the piston seal in the cylinder is not strict, there is a leak between the two chambers of the cylinder, the oil is still in the cylinder, and the external leakage is that the oil leaks to the outside of the cylinder.
