Colombia steel mill cylinder

(Colombia steel mill cylinder,produced by Hengyu Hydraulic Cylinder Factory)

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

Introduction to steel mill cylinder:

steel mill cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.

In order to ensure the service life of the steel mill cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the steel mill cylinder, causing damage to the seal and causing leakage in the steel mill cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

If the steel mill cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the steel mill cylinder. The internal parts of the steel mill cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, and the action resistance is too large, so that the piston speed of the steel mill cylinder changes with the different stroke position, and there is slip or crawl. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the steel mill cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings. At the same time, check whether the lubrication is good or whether the steel mill cylinder bore processing is out of whack. Because the piston and steel mill cylinder, guide rail and piston rod are relative If the steel mill cylinder is crawling seriously, check whether air has entered the hydraulic system. Air compression or expansion can cause the piston to slip or crawl. The exclusion measures are to check the hydraulic pump, set up a special exhaust device, and quickly operate the exhaust several times in the full stroke. Check the seals at the same time, because the quality of the seals is directly related to slippage or crawling. When the O-ring is used under low pressure, compared with the U-ring, it is easy to slip or crawl because of the higher surface pressure and the larger difference between static and static friction resistance. The surface pressure of the U-shaped sealing ring increases with the increase of pressure, although the sealing effect is correspondingly improved, but the difference between static and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase in the contact resistance of the lip, the sealing ring will tip over and the lip elongation, and it is also easy to cause slip or crawling steel mill cylinder weight composition and calculation. The weight of the steel mill cylinder is composed of the steel mill cylinder diameter, the outer diameter and weight of the steel mill cylinder, the rod diameter, and the weight of the accessories, so in calculation, it is to add all these together to get the specific value. However, if there are special circumstances, it may be calculated separately. This work can be carried out by yourself, but it can also be carried out by professionals, so that mistakes can be avoided.

Under normal circumstances, the steel mill cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the steel mill cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the steel mill cylinder and the end cover, the piston and the piston rod, the piston and the steel mill cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the steel mill cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

Answers to some questions about steel mill cylinder:

The cylinder is moving too fast. I want to slow it down. What can I do?
The hydraulic cylinder is the execution action, and the power source is the hydraulic system. The cylinder speed is too fast, indicating that the system flow is large, the hydraulic system has a hydraulic valve responsible for speed control function, method: 1, by adjusting the speed control valve to reduce the speed; 2, the speed control valve has been adjusted to the lowest, indicating that the hydraulic system design flow is too high, the need to re-configure the hydraulic system according to demand, or the cylinder diameter is changed.

How to control the speed of the hydraulic cylinder?
The speed of the hydraulic cylinder is only related to the flow, so the control speed is to control the flow of the hydraulic oil, which is generally adjusted by the throttle valve in the system.
