Burma hydraulic cylinder,rolling mill cylinder manufacturer,rolling mill cylinder

(Burma rolling mill cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to rolling mill cylinder:

When the piston speed of the rolling mill cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the rolling mill cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

rolling mill cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards rolling mill cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the rolling mill cylinder guide is determined by the length of the stroke. Check the strength of rolling mill cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

If the seal of the rolling mill cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.

The assembly work of the rolling mill cylinder has a great impact on the quality of the rolling mill cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.

Answers to some questions about rolling mill cylinder:

What is the material of the lift cylinder?
The cylinder is composed of many parts. The cylinder also contains the seal and the installation port at both ends, the material of these two parts is not easy to determine if there is no physical object. The cylinder body is generally 20 steel, 45 steel, 27SiMn and other materials, and the piston rod is generally 40Cr, 45 steel and other materials.

How to calculate hydraulic cylinder thrust?
Cylinder diameter = piston diameter =200MM Piston area =π (200/2) square =3140 square mm =31.4 square cm 25MPA=250KG/ square cm Maximum thrust = pressure * Piston area =250 *31.4 =7850KG=78500 Newtons This is the maximum thrust. The formula can be derived from the calculation formula.
