Why Should The Hydraulic Cylinder Have A Buffer Device

- Jul 26, 2018 -

When the hydraulic cylinder has a large mass or a large load and a high moving speed (>12 m/s), it has a large momentum due to the large inertia force. In this case, when the piston moves to the end of the cylinder, it will mechanically collide with the end cap, causing great impact and noise. The weight will affect the machining accuracy and even cause a destructive accident. Therefore, it is large, high speed or high. In precision hydraulic equipment, a buffer device is often provided, the purpose of which is to increase the oil return resistance when the piston approaches the terminal, thereby slowing the moving speed of the moving member and avoiding hitting the hydraulic cylinder end cover.
