This article mainly introduces:

Germany hydraulic cylinder,large cylinder manufacturer,large cylinder

Germany large cylinder

(Germany large cylinder,produced by Hengyu Hydraulic Co., Ltd)

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

Introduction to large cylinder:

Causes and countermeasures of oil large cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the large cylinder will lead to premature wear of the piston seal, replace the piston seal; If the large cylinder is visibly scarred, the large cylinder must be replaced. It can be pressurized at one end of the large cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most large cylinder piston drift may not come from the large cylinder, the above method to determine the large cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

When the oil pressure of the large cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.

large cylinder installation precautions: Before installing the large cylinder into the system, the parameters on the large cylinder label should be compared with the parameters when ordering. The base of the large cylinder must have sufficient stiffness, otherwise the large cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

The assembly work of the large cylinder has a great impact on the quality of the large 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 large cylinder:

Where's the hydraulic cylinder bleed valve?
There is a vent hole at the top of the cylinder next to the intake pipe. Generally, it can be used, and the air in the cylinder can be naturally drained after several moves.

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.
