HYDRAULIC DAMPER WITHOUT FREE TRAVEL
category:
The utility model relates to a hydraulic damping device for stably buffering a moving mechanism, which can effectively provide a stable damping force for mechanical movement and prevent the occurrence of abnormal noise.
Description
No free travel hydraulic damper，A hydraulic damping device for stably buffering a moving mechanism.
working principle:Similar in appearance to a gas spring, but works differently, damping through the throttling of hydraulic oil. There is a cylinder inside the hydraulic damper. Since the cylinder has the same outer diameter as the piston rod, when the piston rod extends or retracts, the cylinder also extends or retracts to the same length of the lower chamber, and the upper chamber has the same length. The sum of the volumes of the middle chamber remains the same, and when the upper chamber and the middle chamber are filled with liquid, there is no empty stroke in the entire working stroke of the damper. When applied to a mechanical motion device, it can effectively provide a stable damping force to the mechanical motion and prevent the occurrence of abnormal noise.
Features:
1. Large damping and long life. It is designed with a slender gas spring, the casing and piston rod are coated and wear-resistant, and the service life is long.
2. The hydraulic damper has a complete set of installation accessories to deal with various installation occasions. They are maintenance-free and ready-to-install. Can be used to absorb swing loads.
Use:Automobile manufacturing, machinery manufacturing and electronic industry and other fields.
