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

Introduction to servo hydraulic cylinder:

The servo hydraulic cylinder should be vented: when the servo hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the servo hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the servo hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the servo hydraulic cylinder, the oil is best entered and discharged from the highest point of the servo hydraulic cylinder. servo hydraulic cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

Before purchasing the servo hydraulic cylinder, it is necessary to master the original information and design basis, mainly including: the use and working conditions of the machine; The structural characteristics, load conditions, stroke size and operation requirements of the working mechanism; The selected working pressure and flow of the hydraulic system; The reality of materials, fittings and processes; Relevant national standards and technical specifications, etc.

The viscosity of the working oil used in the servo hydraulic cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

servo hydraulic cylinder buffer valve inspection and maintenance: For the valve buffer servo hydraulic cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

Answers to some questions about servo hydraulic cylinder:

What is the function of the hinged cylinder of the shield machine?
The articulated cylinder is used for the shield when the radius of curvature is very small during the propulsion process, that is, for turning. For example, a propulsion section with a radius of curvature of R150 can only be turned using an articulated system due to the sensitivity of the shield body (i.e. the length of the shield body divided by its outside diameter). However, in the construction process, the use of articulated systems is not much.

Is rubber or polyurethane better for V-ring of hydraulic cylinder?
The hydraulic cylinder V-type seal ring is better with polyurethane, and chlorine rubber is used for various chemicals and high temperatures, especially when there are wear-resistant requirements, polyurethane rubber is needed. But the price of polyurethane rubber is much more expensive than the price of rubber. However, the V-ring material is most commonly used in nitrile and neoprene rubber, and natural rubber is used for sealing water and air. Butyl rubber is used for non-combustible hydraulic fluids and phosphate ester hydraulic fluids. The advantage is that the price is cheaper than the polyurethane material, and the disadvantage is that it is not wear-resistant and the anti-aging property is relatively poor.
