Cote d 'Ivoire hydraulic cylinder,trunnion cylinder manufacturer,trunnion cylinder
(Cote d 'Ivoire trunnion cylinder,produced by Hengyu Group）
trunnion cylinder are widely used in Cote d 'Ivoire，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed trunnion cylinder for customers from Cote d 'Ivoire.
When the oil pressure of the trunnion cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.
trunnion 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 trunnion 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 ' trunnion 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 trunnion cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The trunnion cylinder mainly outputs linear motion and force. The trunnion 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 trunnion cylinder, plunger trunnion cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger trunnion cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.
If the piston rod and trunnion cylinder are stuck or the trunnion cylinder is blocked, at this time, no matter how to operate, the trunnion 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 trunnion cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.
The quality of the trunnion cylinder can not be ignored in the purchase of the trunnion cylinder. The trunnion cylinder is the main component of the trunnion cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. trunnion cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of trunnion cylinder is deep hole processing, which has always troubled the processing personnel.
By what means can the hydraulic system control the arbitrary stroke position of the rotary cylinder piston rod?
The following ways can be considered: 1, through the limit device, such as limit switch, position sensor, etc. 2, by feedback the pressure of the hydraulic oil in the cylinder. The load determines the pressure, the pressure in the cylinder is determined by the load, and the pressure is very small when the cylinder is unloaded. 2.1 When clamping the workpiece, the pressure of the cylinder increases, by calculating the relationship between the clamping force and the pressure of the cylinder, take a pressure value of the cylinder, set the pressure switch, and drive the valve to work when the pressure reaches the preset value, so that the oil circuit stops supplying oil. 2.2 or set the pressure value of the relief valve to overflow after a certain set pressure.
How to make 4 cylinders balance lifting weight at the same time?
The cost of the synchronous valve is lower, 4 cylinders need 3 synchronous valves, to be precise you can use a synchronous motor, but it is more expensive. There is another way, that is to install a throttle valve in each cylinder, respectively adjust the speed of the cylinder.
