trailer hydraulic cylinder are widely used in Japan，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed trailer hydraulic cylinder for customers from Japan.
In recent years, the processing process of the trailer hydraulic cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.
The "O" ring can be used as an auxiliary seal inside the trailer hydraulic cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the trailer hydraulic cylinder, and can be completely sealed.
The trailer hydraulic cylinder should be vented: when the trailer hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the trailer hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the trailer hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the trailer hydraulic cylinder, the oil is best entered and discharged from the highest point of the trailer hydraulic cylinder. trailer hydraulic cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.
The piston seal of the trailer hydraulic cylinder is the main element to prevent leakage in the trailer hydraulic cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.
What are the main dimensions of the cylinder?
The main dimensions of the cylinder include: cylinder inner diameter, piston cylinder diameter, cylinder length, cylinder wall thickness, stroke, installation distance, etc.
The pressure gauge of the hydraulic station reaches 20MPa. How many tons of weight can the hydraulic cylinder lift? How to convert?
20Mpa=200kg/cm^2 The weight of the cylinder with a cross-sectional area of 1 square centimeter can be lifted is 200kg, so F=200X3.14X (125/2) ^2 =24531kg =24.5 tons.
