(UAE supporting cylinder,produced by Hengyu Hydraulic Co., Ltd）

supporting cylinder are widely used in UAE，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed supporting cylinder for customers from UAE.

Introduction to supporting cylinder:

Improve the service life of the supporting 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 supporting cylinder (such as the supporting 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 supporting 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 supporting cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single supporting cylinder exhaust.

The supporting cylinder is not the same as the supporting cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the supporting cylinder can not be used as a high-power power component, but the supporting cylinder can be used as a relatively large power component, or the supporting cylinder system can be used.

The supporting cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the supporting cylinder, bite. Elimination method: When installing the supporting cylinder, ensure that the axis position of the supporting cylinder is consistent with the direction of movement; Make the load borne by the supporting cylinder as far as possible through the supporting cylinder axis, to avoid the phenomenon of eccentricity.

The assembly work of the supporting cylinder has a great impact on the quality of the supporting 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.

Answers to some questions about supporting cylinder:

Where is the tension cylinder used in the excavator?
Get off the inside of the frame, behind the guide wheel (steering wheel, guide wheel). Disassemble the track and take the guide wheel out to see the tensioning cylinder (track spring).

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.
