(Japan stainless steel cylinder,produced by Hengyu Hydraulic Co., Ltd）

stainless steel cylinder are widely used in Japan，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed stainless steel cylinder for customers from Japan.

Introduction to stainless steel cylinder:

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

stainless steel cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.

What kind of process is used in the stainless steel cylinder to make high-quality stainless steel cylinder products: the body is the main component of the stainless steel 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 stainless steel 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 stainless steel 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 stainless steel cylinder increases by 25%. If the service life of the stainless steel 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. stainless steel 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 stainless steel 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 stainless steel cylinder are stuck or the stainless steel cylinder is blocked. At this time, no matter how to manipulate, the stainless steel 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 stainless steel cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

The difference between the integral stainless steel cylinder and the split stainless steel cylinder: The integral stainless steel cylinder and the split stainless steel cylinder in the stainless steel cylinder are two different stainless steel cylinders, and they are very different. The whole stainless steel cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split stainless steel cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and stainless steel cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

Answers to some questions about stainless steel cylinder:

When the superimposed hydraulic control valve is added to the bottom of a solenoid valve and a double directional throttle valve, why does the cylinder shock on the return trip?
The stack hydraulic control check valve must be added above the stack one-way throttle valve.

Why the injection cylinder retreating after the injection molding machine is started?
It is likely that the projected area of the molded plastic parts is large or the injection pressure set is relatively large, resulting in the expansion force exceeding the clamping force of the injection molding machine, so the mold is backward. You can do the following attempts: 1, reduce the injection force of the injection molding machine; 2, if the injection molding part can not be well formed by reducing the injection force, it is recommended to install the mold to a larger injection molding machine.
