Abstract

The invention discloses a dynamic assisting oil filling device and oil filling method for a hydraulic damper. The dynamic assisting oil filling device comprises an industrial personal computer, a data acquisition control system, a displacement sensor, a force sensor, a rack, an oil cylinder, a proportional overflow valve, a proportional directional valve, an oil tank, a hydraulic damper and a vacuum oil filling machine. The dynamic assisting oil filling device and oil filling method for the hydraulic damper, provided by the invention, improve the oil filling quality of the large damper by adopting a cyclic displacement method, and at the same time, increase the oil filling efficiency.

Description

technical field [0001] The invention relates to a dynamic auxiliary oil filling device for a hydraulic damper and an oil filling method thereof, belonging to the field of product manufacturing technology. Background technique [0002] Hydraulic damper is an important pipeline support protection device. The normal operation of the hydraulic damper is closely related to whether it is filled with hydraulic oil. In the assembly of hydraulic dampers, vacuum and gravity are usually used for static filling. This is feasible for small (rated load less than 500kN) hydraulic dampers with relatively simple structures, but for complex and large hydraulic dampers, practice shows that it is difficult to fill the oil with the conventional static oil filling method even if it lasts for several days . The reason is mainly because the air in the damper cavity and the air bubbles in the oil will be blocked in a certain place and difficult to discharge. At this time, if the piston rod of th...
