Cote d 'Ivoire hydraulic cylinder,series synchronous cylinder manufacturer,series synchronous cylinder
(Cote d 'Ivoire series synchronous cylinder,produced by Hengyu Hydraulic Co., Ltd）
series synchronous cylinder are widely used in Cote d 'Ivoire，because of high work efficiency，long service life，excellent fatigue and impact resistance.So our company has designed series synchronous cylinder for customers from Cote d 'Ivoire.
When the series synchronous cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the series synchronous cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.
How to repair the series synchronous cylinder body when it is damaged: When the series synchronous cylinder has trace deformation and shallow tensile marks, the series synchronous cylinder is repaired by strong honing process. The heavy honing process can repair series synchronous 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 series synchronous cylinder can meet the technical requirements.
Because of the slightly complex structure of the buffer series synchronous cylinder, sometimes there will be problems, such as when the series synchronous cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.
Analysis of commonly used seals: The wear ring and slip ring commonly used on the series synchronous cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.
What steel pipe does hydraulic cylinder use? This problem is very general. Carbon steel pipe or ordinary seamless steel pipe are all ok, but then there are rolling, quilting, heat treatment and other steps, and the requirements are different, the wall thickness is different, the material is different. It depends on the circumstances.
What are the requirements for hydraulic cylinder assembly? ① The installation of the cylinder should be solid and reliable. In order to prevent the influence of thermal expansion, in the case of large stroke and hot working conditions, one end of the cylinder must be kept floating.② pipe connection shall not be relaxed.③ The mounting surface of the hydraulic cylinder and the sliding surface of the piston rod should maintain sufficient parallelism and perpendicality.④ The central axis of the moving cylinder should be concentric with the center line of the load force, otherwise it will cause lateral force, which is easy to wear the seal And piston damage. The greater the distance between the supporting points of the piston rod, the smaller its wear. For the hydraulic cylinder of the moving object, the installation should keep the cylinder parallel with the moving object, and the degree of non-parallelism is generally not greater than 0.05mm/m. ⑤The sealing ring should not be installed too tightly, especially the U-shaped sealing ring.
