New Zealand hydraulic cylinder,yg series hydraulic cylinder manufacturer,yg series hydraulic cylinder
(New Zealand yg series hydraulic cylinder,produced by Hebei Hengyu company）
yg series hydraulic cylinder are widely used in New Zealand，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed yg series hydraulic cylinder for customers from New Zealand.
If the piston rod and yg series hydraulic cylinder are stuck or the yg series hydraulic cylinder is blocked, at this time, no matter how to operate, the yg series hydraulic 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 yg series hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.
The scar on the sliding surface of the yg series hydraulic cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the yg series hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.
Causes and countermeasures of oil yg series hydraulic cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the yg series hydraulic cylinder will lead to premature wear of the piston seal, replace the piston seal; If the yg series hydraulic cylinder is visibly scarred, the yg series hydraulic cylinder must be replaced. It can be pressurized at one end of the yg series hydraulic 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 yg series hydraulic cylinder piston drift may not come from the yg series hydraulic cylinder, the above method to determine the yg series hydraulic cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
The meaning of the yg series hydraulic cylinder model marked by the yg series hydraulic cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the yg series hydraulic cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the yg series hydraulic cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.
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.
The two cylinders of the bending machine are out of sync?
Check whether the sliding slide is worn, adjust its tightness, so that both sides are consistent, check whether the two cylinder tubing is connected, tighten the flow valve, pressure, let the cylinder air discharge.
