Belgium hydraulic cylinder,trailer hydraulic cylinder manufacturer,trailer hydraulic cylinder
(Belgium trailer hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）
trailer hydraulic cylinder are widely used in Belgium，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed trailer hydraulic cylinder for customers from Belgium.
When the trailer hydraulic cylinder is customized, if there are high requirements for the quality of the trailer hydraulic cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing 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 trailer hydraulic cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the trailer hydraulic cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.
When the hydraulic oil is not pumped into the trailer hydraulic cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the trailer hydraulic cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.
trailer hydraulic cylinder piston rod material selection and requirements: ① piston rod is usually made of 45 steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. The piston rod is generally designed as a trailer hydraulic cylinder, if the diameter is larger, the hollow piston rod can be used. Made of No. 45 seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the working surface of the rod can be plated with hard chromium. ⑥ The piston rod and the end cap are guided by H8 ' trailer hydraulic cylinder piston rod industry standard: piston rod diameter series of national recommended standard GB/T2348-1993. Piston rod thread size series standard GB/T2350-1980. Please refer to execute. There is no industry standard for piston rods Both the trailer hydraulic cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The trailer hydraulic cylinder mainly outputs linear motion and force. The trailer hydraulic cylinder has a variety of forms, according to the different characteristics of its mechanism it can be divided into piston type, plunger type and swing type three categories, according to the mode of action he can be divided into single action and double action. Piston trailer hydraulic cylinder, plunger trailer hydraulic cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger trailer hydraulic cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.
In order to ensure the service life of the trailer hydraulic cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.
How to select swing cylinder? Under what conditions are they designed and selected?
1, determine the system parameters: ① the weight and the required force; ② Nominal working pressure and range; ③ The time required to travel this distance; 4 oil medium 2, installation method: select the appropriate way for the specific application 3, cylinder diameter and working pressure: determine the cylinder diameter and provide the necessary force required by the system pressure 4, piston rod: determine the minimum piston rod diameter required to withstand the longitudinal bending force, select the appropriate piston rod end and piston rod end thread 5, piston: Whether the seal type is suitable for the application 6, buffer: choose the buffer requirements as appropriate.
When does the cylinder rotate?
The piston rod inside the multistage plunger cylinder can be rotated, and it will rotate when it is subjected to tangential force.
