(Japan servo hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

servo hydraulic cylinder are widely used in Japan，because of excellent temperature resistance，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed servo hydraulic cylinder for customers from Japan.

Introduction to servo hydraulic cylinder:

The repair method of the servo hydraulic cylinder: the repair of the servo hydraulic cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.

What kind of process is used in the servo hydraulic cylinder to make high-quality servo hydraulic cylinder products: the body is the main component of the servo hydraulic cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of body is deep hole processing, which has always troubled the processing personnel. The servo hydraulic cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the body can be improved. The correct rolling process of the servo hydraulic cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the 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 RA3.2-6.3um before rolling to RA0.4-0.8&um, 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 service life of the servo hydraulic cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. servo hydraulic cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the servo hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium. (2) The piston rod and servo hydraulic cylinder are stuck or the servo hydraulic cylinder is blocked. At this time, no matter how to manipulate, the servo hydraulic cylinder does not move or moves very little. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the servo hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

When the hydraulic oil is not pumped into the servo hydraulic cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the servo hydraulic cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

The servo hydraulic cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the servo hydraulic cylinder should pay attention to: the operation should be as far away from the servo hydraulic cylinder as possible, to avoid falling objects, knocking, rubbing the servo hydraulic cylinder coating. When cleaning the servo hydraulic cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the servo hydraulic cylinder when the oil temperature exceeds 70 ° C.

Answers to some questions about servo hydraulic cylinder:

How to exhaust hydraulic cylinder?
Exhaust: The hydraulic system generally does not have exhaust, the use of the tank can exhaust, the oil operation will bring the gas back to the tank, and the tank can be communicated with the atmosphere. The gas will escape from the oil.

What is the valve on the hydraulic cylinder?
Oil valve, relief valve, overload valve, explosion-proof valve, etc., these are very convenient to insert! The oil valve, the overload valve and the blasting valve are very important for larger cylinders. Manufacturers will not offer you the selection. You need to choose the values by yourself according to your system, pump, cylinder, environment, working conditions and other comprehensive consideration!
