(Slovakia servo cylinder,produced by Hengyu Hydraulic Cylinder Factory）

servo cylinder are widely used in Slovakia，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed servo cylinder for customers from Slovakia.

Introduction to servo cylinder:

servo cylinder body inspection: The inner surface of the servo cylinder and the piston seal are the main factors causing the leakage in the servo cylinder, if the servo cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the servo cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

When the servo cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the servo cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the servo cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

The quality of the servo cylinder can not be ignored in the purchase of the servo cylinder. The servo cylinder is the main component of the servo 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. servo 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 servo cylinder is deep hole processing, which has always troubled the processing personnel.

In recent years, the processing process of the servo 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.

Answers to some questions about servo cylinder:

What is the role of the cylinder on the plastic mold? The oil cylinder plays a great role in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the oil 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, sometimes customers require to use hot runner, the price is more expensive, but there are many benefits. It can save raw materials and shorten the molding cycle.

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.
