(Costa Rica trailer hydraulic cylinder,produced by Hengyu Group）
trailer hydraulic cylinder are widely used in Costa Rica，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed trailer hydraulic cylinder for customers from Costa Rica.
The trailer hydraulic cylinder pipe should not be left behind when deburring at both ends after the fixed length processing. In addition, the placement of steel pipes near the site of welding pipeline operations is the cause of welding foreign objects. The pipes placed near the welding operation site should be sealed. It must also be noted that pipe fitting materials should be fully prepared on a dust-free workbench.
trailer hydraulic cylinder and hydraulic station selection: Select the type and structure of the trailer hydraulic cylinder according to the operation requirements of the main engine. According to the external load force borne by the trailer hydraulic cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the trailer hydraulic cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the trailer hydraulic cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the trailer hydraulic cylinder, the diameter of the piston and the piston rod.
The role of the trailer hydraulic cylinder in the mold industry: the trailer hydraulic cylinder has a variety of uses in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the trailer hydraulic cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product to decide, sometimes customers require the use of hot runner, the price is more expensive, but there are many benefits, you can save raw materials, shorten the molding cycle The trailer hydraulic cylinder has an irreplaceable role in the heavy industry production process: it is mainly used in places that need to support heavy objects for a long time, and it can still support heavy objects when the oil pressure is removed, and it is safe and reliable. Can be used underwater, single action, load reversion, nut self-locking to make the load safer, especially in large projects, is easy to operate control and self-locking jack, designed with a safety pressure retaining device, built-in pressure relief valve to prevent overload, to protect the self-locking jack to facilitate safe operation. The connection of the device is connected by high pressure hose and threaded joint, which has the advantages of fast use and overcoming the shortcomings of fast traditional joint oil leakage. It is mainly used for equipment installation and toppling operation in various industries such as electric power, construction, machinery manufacturing, mining, railway bridge, shipbuilding and so on.
When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the trailer hydraulic cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.
How to design the guide sleeve of cylinder diameter 400?
The purpose of the guide sleeve is to guide and seal. Therefore, it is necessary to look at the speed of the piston rod, working pressure and radial force. High speed, medium pressure, no (or very little) radial force, with a Steseal. Low speed and heavy load, medium radial force, combined seal. High speed and heavy load, large radial force, sealed with DU sleeve + copper ring + combination. The combination seal must have a lubricating oil passage, and a seal must be added to the outside of the oil passage.
About the hydraulic cylinder wall thickness problem?
Hydraulic cylinder wall thickness calculation formula: t=PD/200St= pipe wall thickness (minimum thickness) mmP= maximum pressure kg/cm2? d= inner diameter mm? S=δ/5 safety factor δ= minimum tensile strength This case: set the cylinder material 45#, tensile strength 58kg/cm2t=(640X40)/(200X11.6)t=11mm piston output (i.e. Thrust) calculation formula: F1=PD2X(3.14/4)F1=640X42X0.785=8,038kg Note: Square numbers will not be used, all 2's in the text are square codes.
