(Poland self-locking hydraulic cylinder,produced by Hengyu Group）

self-locking hydraulic cylinder are widely used in Poland，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed self-locking hydraulic cylinder for customers from Poland.

Introduction to self-locking hydraulic cylinder:

self-locking hydraulic 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.

If the piston rod and self-locking hydraulic cylinder are stuck or the self-locking hydraulic cylinder is blocked, at this time, no matter how to operate, the self-locking hydraulic cylinder does not move or has little action. 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 self-locking hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

self-locking hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching self-locking hydraulic cylinder block - fine boring self-locking hydraulic cylinder block - grinding self-locking hydraulic cylinder block. The rolling method is: broaching self-locking hydraulic cylinder block - fine boring self-locking hydraulic cylinder block - rolling self-locking hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the self-locking hydraulic cylinder block is about 1-2 days, rolling 1 meter of the self-locking 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 self-locking hydraulic cylinder increases by 25%. If the self-locking 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 self-locking hydraulic cylinders, you must take the rolling production process. After the self-locking 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.

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

Answers to some questions about self-locking hydraulic cylinder:

Hydraulic cylinder performance requirements?
Hydraulic cylinder performance requirements: hydraulic cylinder is the hydraulic system to achieve energy transfer, conversion and control of the working medium, in addition, it is also responsible for the lubrication of the system, rust prevention, corrosion prevention and cooling. The performance of hydraulic oil will make the system flexible, accurate and reliable. Hydraulic performance requirements are determined according to the design parameters of the hydraulic system, operating conditions, the structure of the hydraulic pump and the working environment. Appropriate viscosity and good viscosion-temperature performance Viscosity is an important performance indicator of hydraulic pressure, which has an important impact on the smooth operation of the hydraulic system and the friction parts. The low temperature performance of hydraulic oil includes three aspects: low temperature flow, low temperature start-up and low temperature pumping.

Why are two cylinders not balanced with the balance valve?
Balancing valve is only suitable for occasions with low synchronous accuracy requirements, and proportional valves are recommended for occasions with high precision requirements.
