synchronous hydraulic cylinder are widely used in Azerbaijan，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed synchronous hydraulic cylinder for customers from Azerbaijan.

Introduction to synchronous hydraulic cylinder:

How to repair the synchronous hydraulic cylinder body when it is damaged: When the synchronous hydraulic cylinder has trace deformation and shallow tensile marks, the synchronous hydraulic cylinder is repaired by strong honing process. The heavy honing process can repair synchronous hydraulic 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 synchronous hydraulic cylinder can meet the technical requirements.

If the synchronous hydraulic cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the synchronous hydraulic cylinder. The internal parts of the synchronous hydraulic cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, and the action resistance is too large, so that the piston speed of the synchronous hydraulic cylinder changes with the different stroke position, and there is slip or crawl. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the synchronous hydraulic cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings. At the same time, check whether the lubrication is good or whether the synchronous hydraulic cylinder bore processing is out of whack. Because the piston and synchronous hydraulic cylinder, guide rail and piston rod are relative If the synchronous hydraulic cylinder is crawling seriously, check whether air has entered the hydraulic system. Air compression or expansion can cause the piston to slip or crawl. The exclusion measures are to check the hydraulic pump, set up a special exhaust device, and quickly operate the exhaust several times in the full stroke. Check the seals at the same time, because the quality of the seals is directly related to slippage or crawling. When the O-ring is used under low pressure, compared with the U-ring, it is easy to slip or crawl because of the higher surface pressure and the larger difference between static and static friction resistance. The surface pressure of the U-shaped sealing ring increases with the increase of pressure, although the sealing effect is correspondingly improved, but the difference between static and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase in the contact resistance of the lip, the sealing ring will tip over and the lip elongation, and it is also easy to cause slip or crawling synchronous hydraulic cylinder weight composition and calculation. The weight of the synchronous hydraulic cylinder is composed of the synchronous hydraulic cylinder diameter, the outer diameter and weight of the synchronous hydraulic cylinder, the rod diameter, and the weight of the accessories, so in calculation, it is to add all these together to get the specific value. However, if there are special circumstances, it may be calculated separately. This work can be carried out by yourself, but it can also be carried out by professionals, so that mistakes can be avoided.

The synchronous hydraulic cylinder should be vented: when the synchronous hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the synchronous hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the synchronous hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the synchronous hydraulic cylinder, the oil is best entered and discharged from the highest point of the synchronous hydraulic cylinder. synchronous hydraulic cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

synchronous hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching synchronous hydraulic cylinder block - fine boring synchronous hydraulic cylinder block - grinding synchronous hydraulic cylinder block. The rolling method is: broaching synchronous hydraulic cylinder block - fine boring synchronous hydraulic cylinder block - rolling synchronous hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the synchronous hydraulic cylinder block is about 1-2 days, rolling 1 meter of the synchronous hydraulic cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the synchronous hydraulic cylinder increases by 25%. If the synchronous hydraulic cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality synchronous hydraulic cylinders, you must take the rolling production process. After the synchronous hydraulic cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

Answers to some questions about synchronous hydraulic cylinder:

Why does excavator cylinder oil leak?
Under normal circumstances, the leakage of hydraulic cylinders is divided into internal leakage and external leakage. The external leakage is generally due to damage to the oil seal at the extended end of the piston rod and needs to be replaced. Internal leakage is generally because the oil seal on the piston is damaged, you can try to replace the oil seal here, if the replacement will also leak, then check whether there is damage to the inner wall of the cylinder.

How to disassemble injection molding machine injection cylinder?
If it is not repaired for a long time, it is recommended to open both ends, comprehensively check the oil seal and piston ring inside, this is not much difficulty, pay attention to not install reverse when changing the oil seal, some piston rings are steel rings are rubber rings, and several interfaces of steel rings are not in the same position; Rubber ring pay attention not to install reverse; Be careful not to damage the oil seal when installing, otherwise it will soon leak oil.
