Germany hydraulic cylinder,reset cylinder manufacturer,reset cylinder
(Germany reset cylinder,produced by Hebei Hengyu company）
reset cylinder are widely used in Germany，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed reset cylinder for customers from Germany.
When the reset cylinder is customized, if there are high requirements for the quality of the reset cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the reset cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the reset cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.
When the reset cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the reset cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.
When the reset 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 reset 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.
The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the reset cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.
What is the smallest cylinder size?
The smallest shape cylinder I have ever seen is a hydraulic clamping cylinder in the machine tool industry. Outer diameter 24 mm, total length 23 mm, travel 4 mm. Weighs 0.05 kg. Maximum clamping force 3500 Newtons.
What is the difference between gas-hydraulic pressurized cylinder, pneumatic cylinder and oil cylinder?
The cylinder block is small and the force is large, constant speed and variable speed can be used (easy to change), the adjustment of the output is also convenient, and the freedom of transmission is high. However, maintenance costs and installation costs are high, and there is the trouble of mild oil pollution. Easy cylinder control, low price, easy access to energy. But the force is small, and can not achieve the effect of stable speed. The gas-liquid pressurized cylinder has the advantages of both of the above: environmental protection and energy saving, easy control, and simple adjustment. However, the output of the trip has certain restrictions, more suitable for short trips, large output, but also environmental protection and energy saving and low configuration of the occasion.
