Libya hydraulic cylinder,hydraulic punch cylinder manufacturer,hydraulic punch cylinder
(Libya hydraulic punch cylinder,produced by Hengyu Group）
hydraulic punch cylinder are widely used in Libya，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed hydraulic punch cylinder for customers from Libya.
The wear of the hard chromium plating layer of the hydraulic punch cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
The pressure of the sliding surface of the hydraulic punch cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the hydraulic punch cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.
In order to ensure the service life of the hydraulic punch cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the hydraulic punch cylinder, causing damage to the seal and causing leakage in the hydraulic punch cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.
When the hydraulic punch cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the hydraulic punch cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the hydraulic punch cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the hydraulic punch cylinder can meet the requirements by grinding. However, the life and reliability of this repair hydraulic punch cylinder are not high.
What brand of hydraulic cylinder seal ring is best?
Depending on the specific product, the world famous seal brands are NOK, CFW, PARKER, TSS, WKF, DINGZING DZ, ASTON, HALLITE, TECNOLAN and so on.
What is the HS code of the hydraulic cylinder?
HS code of hydraulic cylinder; 8412210000 8412210000 Linear hydraulic power unit (hydraulic cylinder) 0.12000 0.35000 0.00000 0.17000 0.00000
