servo hydraulic cylinder are widely used in Luxembourg，because of long service life，smooth movement，high work efficiency.So our company has designed servo hydraulic cylinder for customers from Luxembourg.

Introduction to servo hydraulic cylinder:

When the servo hydraulic cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.

When installing the servo hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the servo hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the servo hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the servo hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the servo hydraulic cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

In recent years, the processing process of the servo hydraulic cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

The role of the servo hydraulic cylinder in the mold industry: the servo 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 servo 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 servo 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.

Answers to some questions about servo hydraulic cylinder:

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.

How to calculate multistage cylinder volume?
When the multi-stage cylinder is extended, the largest cylinder is extended first, and when the largest cylinder stroke is completed, the second largest cylinder is extended again, the second largest cylinder stroke is completed, the third largest cylinder is extended again... Therefore, the cylinder extension length is less than the stroke of the largest cylinder, and the volume is the extension length times the inner hole area of the largest cylinder. The cylinder extension length is greater than the maximum cylinder stroke and less than (the largest cylinder stroke + the second largest cylinder stroke), and the volume is the largest cylinder stroke times the internal hole area of the largest cylinder + (the extension length - the largest cylinder stroke) times the second largest cylinder.
