Slovakia hydraulic cylinder,rolling mill cylinder manufacturer,rolling mill cylinder

(Slovakia rolling mill cylinder,produced by Hengyu Hydraulic Co., Ltd）

rolling mill cylinder are widely used in Slovakia，because of no need for deceleration device，long service life，smooth movement.So our company has designed rolling mill cylinder for customers from Slovakia.

Introduction to rolling mill cylinder:

We can not just consider the price and ignore the quality when we purchase the rolling mill cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the rolling mill cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the rolling mill cylinder is not required.

The "O" ring can be used as an auxiliary seal inside the rolling mill cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the rolling mill cylinder, and can be completely sealed.

Disassembly rolling mill cylinder: When disassembly rolling mill cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the rolling mill cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the rolling mill cylinder.

When the rolling mill cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.

Answers to some questions about rolling mill cylinder:

What is a differential cylinder?
The differential cylinder is by connecting the return oil of the rod cavity through the pipeline, allowing them to flow into the rodless cavity, thereby speeding up the extension speed of the piston rod. In fact, the cylinder is still the cylinder, but the oil circuit is related to the connection. The oil connection mode in which both chambers of a single rod hydraulic cylinder are fed hydraulic oil is called differential connection.

What are the cylinder manufacturing processes?
Hydraulic cylinder processing process: 1, cylinder: a, material preparation (seamless steel pipe) → inspection (material certificate, etc.) → tempering (outsourcing: Some parts) → car (car round, shelf mouth, boring, flange stop, etc.) → tempered hardness test → welding (welded pipe joint base, flange and other accessories) → boring or honing (rough boring, fine boring, rolling) → car (hole slot or internal and external thread) → fitter (drilling) → inspection → rust prevention storage b, material preparation (forgings) → inspection (material certificate, inspection, etc.) → welding (blank butt welding) → welding inspection → car (rough car) → quality control (outsourcing: some parts) → car (car round, shelf mouth, boring stop, flange stop, etc.)
