Estonia servo cylinder

(Estonia servo cylinder,produced by Hengyu Group)

servo cylinder are widely used in Estonia,because of no transmission clearance,clever hydraulic energy conversion,powerful torque.So our company has designed servo cylinder for customers from Estonia.

Introduction to servo cylinder:

If the servo cylinder slips or crawls, please check whether there is astringency inside the servo cylinder, because the internal parts of the servo cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the servo cylinder changes with the different stroke position, and the slip or crawl occurs. 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 servo 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.

The assembly work of the servo cylinder has a great impact on the quality of the servo cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.

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

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

Answers to some questions about servo cylinder:

How to repair the bent oil cylinder correctly?
If the bending oil cylinder leaks, the most direct way is to replace the seal ring. Most of the sealing rings used by domestic bending machines are made in Taiwan and Japan, so the service life of the sealing ring is still relatively long. If the bending oil cylinder used by the customer leaks oil, then when replacing the seal ring, be sure to choose a high-quality and durable seal ring. In this way, the replaced cylinder will not leak oil for a long time.

When there is only one hole in the oil inlet and outlet of the hydraulic cylinder, will there be oil leakage?
It is a single acting oil cylinder. This oil cylinder is always driven by hydraulic oil in advance, and is generally pulled back by the spring at the bottom of the piston or the weight of the cylinder piston or the load. But either way, it has nothing to do with any internal leakage. Whether the oil is internally drained is related to the sealing and accuracy of the cylinder itself.
