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

rolling mill cylinder are widely used in Singapore，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed rolling mill cylinder for customers from Singapore.

Introduction to rolling mill cylinder:

The rolling mill cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the rolling mill cylinder, bite. Elimination method: When installing the rolling mill cylinder, ensure that the axis position of the rolling mill cylinder is consistent with the direction of movement; Make the load borne by the rolling mill cylinder as far as possible through the rolling mill cylinder axis, to avoid the phenomenon of eccentricity.

If it is found that the rolling mill cylinder lubrication is poor or the rolling mill cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the rolling mill cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the rolling mill cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the rolling mill cylinder center line. In this way, when the piston works in the rolling mill cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the rolling mill cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

rolling mill cylinder and hydraulic station selection: Select the type and structure of the rolling mill cylinder according to the operation requirements of the main engine. According to the external load force borne by the rolling mill cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the rolling mill cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the rolling mill cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the rolling mill cylinder, the diameter of the piston and the piston rod.

The scar on the sliding surface of the rolling mill cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the rolling mill cylinder wall. Therefore, before installation, these scars must be fully repaired.

Answers to some questions about rolling mill cylinder:

How to calculate the hydraulic cylinder pressure, how much pressure can put up how much weight?
There is a formula for air pressure, hydraulic pressure, water pressure: F=P×S type: f-cylinder or hydraulic cylinder output, unit is Newton (N) P- pressure, unit is Mpa S- effective area, unit is square millimeter (mm2), note: is the effective area, in the hydraulic cylinder to subtract the cross-sectional area of the piston rod.

Design a hydraulic cylinder, the inner diameter of the cylinder is 100mm, what size of piston rod is best used?
This involves how much speed ratio you need, that is, the area ratio of the rod cavity and the rodless cavity, if the weight is relatively large, it is recommended that the speed ratio choose 2, that is, the piston rod diameter choose 70mm, under normal circumstances, the speed ratio choose 1.46, the piston rod diameter choose 55mm. Of course, there are many factors that affect the diameter of the piston rod, such as stroke, stroke is too long, in order to stabilize the work of the hydraulic cylinder, its diameter also needs to choose a relatively large, sometimes even non-standard products, need to choose according to the actual situation.
