(Costa Rica rolling mill cylinder,produced by Hengyu Group）

rolling mill cylinder are widely used in Costa Rica，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed rolling mill cylinder for customers from Costa Rica.

Introduction to rolling mill cylinder:

In use, the rolling mill cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the rolling mill cylinder.

The rolling mill cylinder is mainly composed of body, piston, piston rod, rolling mill cylinder head, rolling mill cylinder bottom, piston rod head and related auxiliary devices. The piston divides the rolling mill cylinder into two chambers, and moves reciprocally in the rolling mill cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the rolling mill cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the rolling mill cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the rolling mill cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the rolling mill cylinder bottom and the rolling mill cylinder head is serious, so the buffer deceleration should be set at both ends of the rolling mill cylinder The working medium of the rolling mill cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; rolling mill cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the rolling mill cylinder: The buffer structure of the rolling mill cylinder is to prevent the piston from colliding with the rolling mill cylinder head at the end of the stroke.

When the rolling mill cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the rolling mill cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the rolling mill cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

The body of the rolling mill cylinder on the processing process requirements: the body of the rolling mill cylinder is an important and essential part of the rolling mill cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the rolling mill cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

Answers to some questions about rolling mill cylinder:

What is a constant velocity cylinder? What is the difference between hydraulic cylinder and constant velocity cylinder?
The constant speed cylinder should be the same as the speed of the piston rod extension and withdrawal cylinder is called the constant speed cylinder. The difference between it and the ordinary hydraulic cylinder is that the ordinary hydraulic cylinder only has a piston rod extended out, and the general extension speed is slow and the recovery speed is fast, because of the relationship between the effective area. Effective area of piston chamber > Effective area of piston rod chamber. The effective area on both sides of the constant speed cylinder is the same, because there are piston rods sticking out at both ends. The application of constant speed cylinder is most common in grinding machines.
