Malaysia hydraulic cylinder,steel mill cylinder manufacturer,steel mill cylinder(Malaysia steel mill cylinder,produced by Hengyu Group)
steel mill cylinder are widely used in Malaysia,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed steel mill cylinder for customers from Malaysia.
If it is found that the steel mill cylinder lubrication is poor or the steel mill cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the steel mill cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the steel mill cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the steel mill cylinder center line. In this way, when the piston works in the steel mill cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the steel mill cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.
The internal leakage of the steel mill cylinder is an important indicator to measure the quality of the steel mill cylinder: the internal leakage of the steel mill cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the steel mill cylinder, so that the steel mill cylinder can not accurately and stably stop in a certain position of the steel mill cylinder, so it is one of the main indicators of the steel mill cylinder.
The viscosity of the working oil used in the steel mill cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.
The oil steel mill cylinder is a part of the hydraulic system, in the hydraulic system, to reasonably design the heat dissipation system, to prevent the oil temperature is too high is the key to keep the hydraulic oil temperature normal. The temperature of the system should be kept in a suitable range to reduce the energy released when the bubble bursts. While not affecting the normal circulation of the coolant, a certain amount of anti-corrosion additives can be appropriately added to inhibit rust. When operating the hydraulic system, we should strive to be stable, not too fast, too strong, and try to reduce the impact of hydraulic oil on hydraulic components.
Why are two cylinders not balanced with the balance valve?
Balancing valve is only suitable for occasions with low synchronous accuracy requirements, and proportional valves are recommended for occasions with high precision requirements.
How to determine the rated working pressure of the hydraulic cylinder?
Under normal circumstances, the working pressure is determined according to the size of the load and the installation space (the allowable diameter of the cylinder). In some special occasions, the smaller the cylinder, the better, the pressure level must be increased. The cylinder pressure is related to the estimated cost. The higher the pressure, the thicker the wall, the higher the cost, but conversely, the lower the pressure, the larger the diameter of the cylinder (when the same thrust) is required, the same high cost. Therefore, the rated pressure of the cylinder is concentrated in about 35 mpa, taking into account the cylinder diameter and wall thickness.
