Sweden hydraulic cylinder,steering power cylinder manufacturer,steering power cylinder(Sweden steering power cylinder,produced by Hengyu Group)
steering power cylinder are widely used in Sweden,because of excellent temperature resistance,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed steering power cylinder for customers from Sweden.
The wear of the hard chromium plating layer of the steering power cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
When the control pressure of the hydraulic system is too low, the steering power 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 viscosity of the working oil used in the steering power cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.
steering power cylinder and hydraulic station selection: Select the type and structure of the steering power cylinder according to the operation requirements of the main engine. According to the external load force borne by the steering power cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the steering power 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 steering power cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the steering power cylinder, the diameter of the piston and the piston rod.
How to calculate the hydraulic cylinder pressure? How much pressure can put up how much weight?
If you want to calculate the pressure of the cylinder, you must know the inner diameter of the cylinder, if the piston rod is needed to lift the weight, it should be: cylinder (no piston rod end) pressure = load (4000N) ÷{(PI /4)X the square of the cylinder diameter (mm) ", it has nothing to do with the piston rod diameter, the rod diameter of the piston rod is only related to the stability of the cylinder. The pressure inside the cylinder should be p=F/S=400×10/(3.14×(0.5×25)×(0.5×25))=8.15MPa which means that you need to provide at least that much pressure to complete the operation.
What is the thin cylinder used for?
The principle is no different from ordinary cylinders, that is, the installation space is small, the formation is small, and it is suitable for some special occasions. For example, the space is compact and the place of small travel is used.
