(Saudi Arabia rolling mill cylinder,produced by Hebei Hengyu company）

rolling mill cylinder are widely used in Saudi Arabia，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed rolling mill cylinder for customers from Saudi Arabia.

Introduction to rolling mill cylinder:

When using the rolling mill cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the rolling mill cylinder block. If the rolling mill cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the rolling mill cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the rolling mill cylinder, so that the working efficiency of the rolling mill cylinder is reduced.

When the rolling mill cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the rolling mill cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

Most of the failure of the rolling mill cylinder is because there is a foreign body in the rolling mill cylinder into the failure of the rolling mill cylinder, the most problematic is that it is difficult to determine when the foreign body is into the rolling mill cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

In order to ensure the service life of the rolling mill cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.

Answers to some questions about rolling mill cylinder:

Why the cylinder cannot operate normally after the explosion-proof valve is installed?
The pipeline explosion-proof valve is specially designed to prevent pipeline damage and free fall of the cylinder, so there must be back pressure to open. If there is no oil return pressure, or the oil return pressure is too small, and can not adjust the oil return pressure, such a system with explosion-proof valves is more troublesome, it is recommended to add a one-way throttle valve between the cylinder and the tank to establish back pressure. If you understand the explosion-proof valve, you can also try to adjust the opening of the valve (that is, the flow of the regulating valve), and adjust the opening to help the valve to open.

The diameter of the cylinder is 180mm and the pressure is 14mpa. How many tons can the cylinder hold?
Calculate the area of the cylinder, 3.14*9*9=254.34 square centimeters, take the approximate number of engineering, 1 mpa pressure is about 10 kg per square centimeter, 14 mpa pressure is 140 kg per square centimeter, that is 254.34*140=35607.6 kilograms, it can be known that the cylinder can be about 35 tons in theory.
