Italy hydraulic cylinder,tailboard balance cylinder manufacturer,tailboard balance cylinder
(Italy tailboard balance cylinder,produced by Hengyu Group）
tailboard balance cylinder are widely used in Italy，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed tailboard balance cylinder for customers from Italy.
Causes and countermeasures of oil tailboard balance cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the tailboard balance cylinder will lead to premature wear of the piston seal, replace the piston seal; If the tailboard balance cylinder is visibly scarred, the tailboard balance cylinder must be replaced. It can be pressurized at one end of the tailboard balance 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 tailboard balance cylinder piston drift may not come from the tailboard balance cylinder, the above method to determine the tailboard balance cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
tailboard balance cylinder body inspection: The inner surface of the tailboard balance cylinder and the piston seal are the main factors causing the leakage in the tailboard balance cylinder, if the tailboard balance cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the tailboard balance cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.
When the tailboard balance cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the tailboard balance cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.
tailboard balance cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the tailboard balance cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the tailboard balance cylinder. c. The tailboard balance cylinder seal is extruded, if the O-ring is obviously extruded at the tailboard balance cylinder seal, replace the tailboard balance cylinder seal.
What is the bearing capacity of the HOB cylinder?
The normal specification of HOB is 140 kg pressure, which is more commonly used in the market, and there are clear marks on the cylinder, 210 kg is a strengthened version of HOB, generally customized cylinders are also clearly marked on the above, when the specific use of the cylinder, the maximum use pressure is marked on the cylinder.
How to calculate the hydraulic cylinder pressure? How much pressure can put up how much weight?
If you want to calculate the pressure of the cylinder, you must know the inner diameter of the cylinder, if the piston rod is needed to lift the weight, it should be: cylinder (no piston rod end) pressure = load (4000N) ÷{(PI /4)X the square of the cylinder diameter (mm) ", it has nothing to do with the piston rod diameter, the rod diameter of the piston rod is only related to the stability of the cylinder. The pressure inside the cylinder should be p=F/S=400×10/(3.14×(0.5×25)×(0.5×25))=8.15MPa which means that you need to provide at least that much pressure to complete the operation.
