Uruguay hydraulic cylinder,servo hydraulic cylinder manufacturer,servo hydraulic cylinder(Uruguay servo hydraulic cylinder,produced by Hebei Hengyu company)
servo hydraulic cylinder are widely used in Uruguay,because of no need for deceleration device,high work efficiency,excellent fatigue and impact resistance.So our company has designed servo hydraulic cylinder for customers from Uruguay.
The oil servo hydraulic 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.
The quality of the servo hydraulic cylinder can not be ignored in the purchase of the servo hydraulic cylinder. The servo hydraulic cylinder is the main component of the servo hydraulic cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. servo hydraulic cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of servo hydraulic cylinder is deep hole processing, which has always troubled the processing personnel.
The internal leakage of the servo hydraulic cylinder is an important indicator to measure the quality of the servo hydraulic cylinder: the internal leakage of the servo hydraulic cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the servo hydraulic cylinder, so that the servo hydraulic cylinder can not accurately and stably stop in a certain position of the servo hydraulic cylinder, so it is one of the main indicators of the servo hydraulic cylinder.
The body of the servo hydraulic cylinder on the processing process requirements: the body of the servo hydraulic cylinder is an important and essential part of the servo hydraulic cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the servo hydraulic cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.
What is the clearance between the cylinder and the piston?
The gap between the cylinder and the piston in the radius is generally 40 wires, that is, about 0.4mm, and the gap of the cylinder with different diameters will be slightly different. Generally, the inner diameter of the cylinder is larger than the outer diameter of the piston, so as to prevent the friction between the outer surface and the inner surface of the cylinder during the operation of the piston. In order to ensure that the cylinder has a rod cavity and a rodless cavity seal, a sealing device, that is, a sealing ring, is installed on the outer surface of the piston. The sealing ring form is not exactly the same, the O-type sealing ring is generally used under low pressure, and the lip sealing ring is used under high pressure. At the same time, the outer circle of the piston is also equipped with a dust ring and a wear ring. As long as the cylinder seal fails, all the internal seals should be replaced.
The pressure gauge of the hydraulic station reaches 20MPa. How many tons of weight can the hydraulic cylinder lift? How to convert?
20Mpa=200kg/cm^2 The weight of the cylinder with a cross-sectional area of 1 square centimeter can be lifted is 200kg, so F=200X3.14X (125/2) ^2 =24531kg =24.5 tons.
