The Advantages of Hydraulic Cylinders and the Key to Load

After the surface layer of the metal material product workpiece of the hydraulic cylinder is extruded and processed, the surface obtains enhanced ultimate compressive strength and yield limit expansion. The performance indicators, fatigue resistance limit, wear resistance and corrosion resistance of the product workpiece have been significantly improved. After extrusion, when it comes to the strength of the hydraulic cylinder such as the excavator hydraulic cylinder, in fact, it will increase by 15% ~ 30%, and the wear resistance will increase by 15%.

1. Advantages of hydraulic cylinders

The hydraulic cylinder will immediately increase the roughness from Ra6.3 to Ra2.4~Ra0.2 when the extrusion molding process is carried out. Moreover, it has high productivity, and some product workpieces can be carried out in a few minutes or seconds; extrusion molding production and processing can also solve some critical problems that are not easy to complete in the current processing methods.

For example, the production and processing of super-large engine blocks. In addition, it is also suitable for the casting and rolling production of extra-small round holes or the casting and rolling production and processing of some materials.

Hydraulic cylinders have a wide range of applications after extrusion production and processing, and can be used in large, medium and small factories. No matter in terms of production and processing quality, productivity, custom metal forgings product cost, etc., extrusion molding production and processing is an excellent production and processing method. It can completely replace the finishing production and processing such as fine polishing, grinding and honing, which ensures the quality of hydraulic cylinder machinery and equipment.

2. What is the key to the hydraulic cylinder load?

The output force of the hydraulic cylinder is positively correlated with the reasonable total area of the piston rod and the pressure difference on both sides; the hydraulic cylinder is mostly composed of the cylinder liner and the cylinder head, the piston rod and the hydraulic cylinder, the sealing equipment, the buffer equipment and the air-water separator. The cache equipment and gas-water separator depend on the actual application site, and other equipment is indispensable.

1) Inhibiting force: According to the connection method of the hydraulic cylinder and the hydraulic cylinder: F=100KN;

2) Friction and acting force: Because the frictional resistance and acting force of the hydraulic cylinder have relatively little restraining force, they can be ignored.

3) Inertial force friction resistance: Because the custom made hydraulic cylinders moves at a small speed during operation, it does not belong to the rapid and repeated movement type, so the inertial force friction resistance can be ignored.

4) Sealing frictional resistance and condensing frictional resistance: The sealing frictional resistance is taken into account in the mechanical energy of the hydraulic cylinder. The mechanical energy of the hydraulic cylinder is 0.92; the condensing frictional resistance is 1MPa.
