Kuwait hydraulic cylinder,high pressure cylinder manufacturer,high pressure cylinder(Kuwait high pressure cylinder,produced by Hengyu Group)
high pressure cylinder are widely used in Kuwait,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed high pressure cylinder for customers from Kuwait.
When the control pressure of the hydraulic system is too low, the high pressure cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.
In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular high pressure cylinder action. Troubleshooting method: Replace the rubber hose.
When the piston speed of the high pressure cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the high pressure cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
If the piston rod and high pressure cylinder are stuck or the high pressure cylinder is blocked, at this time, no matter how to operate, the high pressure 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 high pressure cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.
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.
How to set up the one-way cylinder hydraulic system?
Single acting oil cylinder, that is, an oil cylinder with an oil port, can use two three-way valves to control the cylinder action. The three oil ports are respectively connected to P (oil pump), A (oil cylinder), and T (oil tank). If the oil pump is to run continuously, an electromagnetic relief valve can be added. When the cylinder is not moving, the relief valve can unload the oil pump. You can also add a three-way four-way valve, the middle function is unloaded, two outlets: A connected to the fuel tank, B connected to the cylinder.
