(Bangladesh hydraulic servo cylinder,produced by Hebei Hengyu company）
hydraulic servo cylinder are widely used in Bangladesh，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed hydraulic servo cylinder for customers from Bangladesh.
When the hydraulic servo cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the hydraulic servo cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.
The hydraulic servo cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the hydraulic servo cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the hydraulic servo cylinder wall due to the stiffness and the weight of the parts, causing scars.
When the control pressure of the hydraulic system is too low, the hydraulic servo 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.
The definition of the minimum stable speed refers to the minimum movement speed of the hydraulic servo cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the hydraulic servo cylinder that undertakes different work has different requirements for the minimum stable speed.
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.
What kind of seal ring we should choose for 120Mpa hydraulic cylinder?
The sealing rings used in mining machinery are high pressure, which can reach 150MPa. It is generally composed of three parts, the guide ring, the sealing body and the elastomer. It's not a special structure. It's more mature. Usually said mountain circle, bud circle.
