(Costa Rica flanged hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）
flanged hydraulic cylinder are widely used in Costa Rica，because of powerful torque，excellent temperature resistance，no need for deceleration device.So our company has designed flanged hydraulic cylinder for customers from Costa Rica.
Most of the failure of the flanged hydraulic cylinder is because there is a foreign body in the flanged hydraulic cylinder into the failure of the flanged hydraulic cylinder, the most problematic is that it is difficult to determine when the foreign body is into the flanged hydraulic 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.
The difference between the integral flanged hydraulic cylinder and the split flanged hydraulic cylinder: The integral flanged hydraulic cylinder and the split flanged hydraulic cylinder in the flanged hydraulic cylinder are two different flanged hydraulic cylinders, and they are very different. The whole flanged hydraulic cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split flanged hydraulic cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and flanged hydraulic cylinder damage. Therefore, it is obvious that the answer to this question is for difference.
Causes and countermeasures of oil flanged hydraulic cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the flanged hydraulic cylinder will lead to premature wear of the piston seal, replace the piston seal; If the flanged hydraulic cylinder is visibly scarred, the flanged hydraulic cylinder must be replaced. It can be pressurized at one end of the flanged hydraulic cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most flanged hydraulic cylinder piston drift may not come from the flanged hydraulic cylinder, the above method to determine the flanged hydraulic cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
The pressure of the sliding surface of the flanged hydraulic cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the flanged hydraulic cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.
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 st represented in the cylinder formula?
St is the original unit of kinematic viscosity, the abbreviation of Stokes, that is, Stokes, short for S. cm2/s has now been used. 1 s (St) = 10^-4m2/s.
