Ethiopia hydraulic cylinder,tension cylinder manufacturer,tension cylinder(Ethiopia tension cylinder,produced by Hengyu Hydraulic Co., Ltd)
tension cylinder are widely used in Ethiopia,because of long service life,smooth movement,high work efficiency.So our company has designed tension cylinder for customers from Ethiopia.
When the control pressure of the hydraulic system is too low, the tension cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.
The tension cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.
If it is found that the tension cylinder lubrication is poor or the tension cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the tension cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the tension cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the tension cylinder center line. In this way, when the piston works in the tension cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the tension cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.
When the tension cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the tension cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.
100 tons press, the cylinder diameter is 250, how much pressure?
100 tons hydraulic press, if it is a single acting hydraulic cylinder, the required oil pressure is the nominal force divided by the cross-sectional area of the cylinder piston. One hundred tons of its pressure is 1000 kN (1000000N), the diameter of the cylinder is 250 mm, its area is the circular rate multiplied by the square of the radius, is 49062.5 square mm, and then the pressure divided by the area of the oil pressure is 20.38MPa. Therefore, a hydraulic pressure of 20.38 mpa is required for a 250 diameter cylinder to obtain 100 tons of pressure.
What is the rated pressure of the general cylinder?
This depends on the model of the cylinder, 1. The rated pressure of the light tie rod cylinder is 7 series 7MPa and 14 series 14MPa. 2. Rated pressure of engineering cylinder 16MPa. 3. Rexroth type metallurgical cylinder rated pressure 250MPa.
