Kuwait hydraulic cylinder,pusher hydraulic cylinder manufacturer,pusher hydraulic cylinder(Kuwait pusher hydraulic cylinder,produced by Hengyu Group)
pusher hydraulic cylinder are widely used in Kuwait,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed pusher hydraulic cylinder for customers from Kuwait.
pusher hydraulic cylinder can not drive the load troubleshooting: oil pressure is too low. pusher hydraulic cylinder selection specifications are too small. Leakage in pusher hydraulic cylinder or associated hydraulic system element.
The piston rod and guide sleeve function of the pusher hydraulic cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.
The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the pusher hydraulic cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.
When the pusher hydraulic cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the pusher hydraulic cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.
What is the material of the cylinder support ring?
Generally, it is polytetrafluoroethylene doped with copper powder, or polyformaldehyde, and copper sleeves, there are also nylon, resin and so on.
How is the cylinder of hydraulic cylinder processed?
As the main parts of hydraulic cylinder, mining single pillar, hydraulic support, gun barrel and other products, its processing quality directly affects the life and reliability of the whole product. Cylinder processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of cylinder is deep hole processing, which has always troubled the processing personnel. Due to the residual compressive stress on the surface of the surface layer, the rolling machining is helpful to seal the small cracks on the surface and prevent the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the cylinder can be improved.
