(Holland servo hydraulic cylinder,produced by Hebei Hengyu company）

servo hydraulic cylinder are widely used in Holland，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed servo hydraulic cylinder for customers from Holland.

Introduction to servo hydraulic cylinder:

Protection of the servo hydraulic cylinder surface: During the dismantling process, safety protection should be carried out on the servo hydraulic cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the servo hydraulic cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the servo hydraulic cylinder should be cleaned up in time.

Before the servo hydraulic cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the servo hydraulic cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

Do not regularly check the damage of the chrome layer of the servo hydraulic cylinder: completely extend the servo hydraulic cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the servo hydraulic cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the servo hydraulic cylinder seal. Welding slag is strictly prohibited on the surface of the servo hydraulic cylinder.

Answers to some questions about servo hydraulic cylinder:

How to calculate cylinder pressure?
Hydraulic pressure area of cylinder × hydraulic pressure = output force of cylinder 200mm=20cm 100mm=10cm 15Mpa=150Kg/cm2 Cylinder thrust: 3.14×10×10 area ×150 pressure =47100Kg=47.1t cylinder pulling force: 3.14×(10×10-5×5) Area ×150 pressure =35325Kg=35.325t The above calculation did not consider the resistance of oil return, because you did not provide oil return pressure. But the impact should be small.

How to calculate the cylinder diameter, rod diameter and pressure of the cylinder, and how to output tonnage?
Hydraulic cylinder output force F=PAX10^3(KN) F is the output force (KN), P working pressure (MPa), A is the piston or plunger area of action.
