Problems solved by technology

In the application process of the hydraulic damper, the oil leakage of the hydraulic damper often occurs. Once the hydraulic damper leaks oil, it will pollute the environment on the one hand, and on the other hand, the hydraulic damper will lose its damping function and cannot work normally.

Abstract

The invention discloses a hydraulic damper with the external leakage preventing function. The hydraulic damper comprises a right pin head, a right end cover, an external cylinder barrel, an auxiliaryfuel tank right piston, an internal cylinder barrel, a damper piston, a damper piston rod, an auxiliary fuel tank left piston, a left end cover, a left pin head, an auxiliary fuel tank piston reset spring and a middle cylinder barrel. Through innovative structural design, double layers of sealing devices are arranged between the piston rod and the end cover of the hydraulic damper; a leaking fuelgroove is formed between the double layers of sealing devices; and fuel is guided out through a related oil way to enter a low-pressure auxiliary fuel tank, so that the external leaking risk of the hydraulic damper is greatly reduced, working reliability of the hydraulic damper is ensured, and the hydraulic damper has a wide application prospect.

Description

technical field [0001] The invention relates to a hydraulic damper, in particular to a hydraulic damper with the function of preventing external leakage, and belongs to the fields of machinery, hydraulic pressure, damping buffer, anti-seismic and the like. Background technique [0002] At present, hydraulic dampers have been widely used in the field of anti-seismic shock absorption. In the application process of the hydraulic damper, the oil leakage of the hydraulic damper often occurs. Once the hydraulic damper leaks oil, it will pollute the environment on the one hand, and on the other hand, the hydraulic damper will lose its damping function and cannot work normally. . There are two forms of leakage of hydraulic dampers: internal leakage and external leakage. In particular, external leakage needs to be strictly controlled. In some special occasions, external leakage of hydraulic dampers is strictly prohibited. External leakage of hydraulic cylinders generally exists in d...
