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

Introduction to hydraulic punch cylinder:

Before purchasing the hydraulic punch cylinder, it is necessary to master the original information and design basis, mainly including: the use and working conditions of the machine; The structural characteristics, load conditions, stroke size and operation requirements of the working mechanism; The selected working pressure and flow of the hydraulic system; The reality of materials, fittings and processes; Relevant national standards and technical specifications, etc.

If the hydraulic punch cylinder slips or crawls, please check whether there is astringency inside the hydraulic punch cylinder, because the internal parts of the hydraulic punch 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 hydraulic punch 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 hydraulic punch 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.

If the piston rod and hydraulic punch cylinder are stuck or the hydraulic punch cylinder is blocked, at this time, no matter how to operate, the hydraulic punch cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the hydraulic punch cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

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

Answers to some questions about hydraulic punch cylinder:

How to distinguish high pressure cylinder and low pressure cylinder?
There is no special definition of the cylinder, the so-called pressure classification refers to the pump low pressure (code L) container 0.1MPa ≤p < 1.6MPa; Medium pressure (code M) container 1.6MPa ≤p < 10.0MPa; High pressure (code H) vessel 10 MPa≤p < 100 MPa; Ultra-high pressure (code U) container p≥100MPa. (1MPa=9.8Kg)

How to judge the failure of forklift hydraulic cylinder?
The common faults of the hydraulic cylinder of forklift truck are mainly crawling, insufficient thrust, working speed decline or even stop. Generally, crawling occurs at low speed. The main reason is that the air stored in the cylinder is not cleared. In addition, excessive or uneven mechanical friction can also cause crawling. Such as the piston and the piston rod different heart, the piston rod full length or local bending, the cylinder hole straightness is poor, the cylinder is drum shaped or has a large taper, the cylinder thin finish decline or produce hair, the cylinder installation accuracy is out of whack, the piston rod nuts at both ends of the screw too tight to make its concentricity is poor, the oil seal screw too tight friction is too large, will cause crawling.
