(El Salvador servo hydraulic cylinder,produced by Hebei Hengyu company）

servo hydraulic cylinder are widely used in El Salvador，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed servo hydraulic cylinder for customers from El Salvador.

Introduction to servo hydraulic cylinder:

When purchasing the servo hydraulic cylinder, try to clarify the following parameters of the servo hydraulic cylinder: A. servo hydraulic cylinder diameter, rod diameter, stroke; B. Working pressure or servo hydraulic cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right servo hydraulic cylinder type can be found accurately and quickly.

servo hydraulic cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the servo hydraulic cylinder is placed for a period of time, the servo hydraulic cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

In use, the servo hydraulic cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the servo hydraulic cylinder.

servo hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching servo hydraulic cylinder block - fine boring servo hydraulic cylinder block - grinding servo hydraulic cylinder block. The rolling method is: broaching servo hydraulic cylinder block - fine boring servo hydraulic cylinder block - rolling servo hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the servo hydraulic cylinder block is about 1-2 days, rolling 1 meter of the servo hydraulic cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the servo hydraulic cylinder increases by 25%. If the servo hydraulic cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality servo hydraulic cylinders, you must take the rolling production process. After the servo hydraulic cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

Answers to some questions about servo hydraulic cylinder:

What diameter cylinder is needed for a force of 5 tons?
It depends on the pressure of your system pump. If the normal working pressure of the system is about 8MPa, then the diameter of the cylinder should be 100 mm.

In hydraulic equipment, is the motor power related to the cylinder pressure holding time?
Irrelevant. The motor only drives the plunger in the hydraulic cylinder of the oil pump to extend out, and stops when the set pressure is reached; The length of the pressure holding time is related to the sealing degree of the hydraulic cylinder and the solenoid valve.
