(Dominica roller press hydraulic cylinder,produced by Hengyu Group）
roller press hydraulic cylinder are widely used in Dominica，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed roller press hydraulic cylinder for customers from Dominica.
When installing the roller press hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the roller press hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the roller press hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the roller press hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the roller press hydraulic cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.
roller press 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.
When the piston speed of the roller press hydraulic cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the roller press hydraulic cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the roller press hydraulic cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.
How to calculate hydraulic cylinder flow?
Effective area of the cylinder x stroke = volume usually in liters. Volume/estimated total travel time (converted to minutes) = oil flow rate.
What diameter cylinder is needed for a force of 5 tons?
It depends on the pressure of your system pump. If the normal working pressure of the system is about 8MPa, then the diameter of the cylinder should be 100 mm.
