Sudan hydraulic cylinder,rolling mill cylinder manufacturer,rolling mill cylinder

(Sudan rolling mill cylinder,produced by Hebei Hengyu company）

rolling mill cylinder are widely used in Sudan，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed rolling mill cylinder for customers from Sudan.

Introduction to rolling mill cylinder:

In the process of using the rolling mill cylinder, sometimes such a problem will occur, the rolling mill cylinder can not act immediately after the instruction of the rolling mill cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil rolling mill cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

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

Answers to some questions about rolling mill cylinder:

How to store hydraulic cylinder?
After cleaning the hydraulic cylinder with diesel or kerosene, apply lubricating oil and wrap it in oil paper, preferably in a wooden box, and store it in a dry and non-corrosive environment. The outer surface and inner surface of the hydraulic cylinder are sprayed with diesel oil, and the inner layer is covered with cloth and the outer coating of anti-rust oil is good. Put it in a dry place, clean it with diesel oil, and then apply a layer of anti-rust inside and outside the butter.

Hydraulic cylinder load algorithm?
If it is thrust, load = working pressure x piston area. If it is pulling force, load = working pressure x(piston area - piston rod area).
