AI Technical Summary
During use, the existing hydraulic breaker cylinder is difficult to effectively absorb the impact and vibration caused by the piston movement during use, resulting in unstable piston movement and reducing the operating efficiency and service life of the equipment. At the same time, the airbag is prone to exceed the pressure resistance limit during inflation, resulting in rupture or failure, and the filter is easily damaged by the piston, which has a short service life.
A hydraulic breaker mid-cylinder assembly is designed, including a shock absorbing mechanism and a filtering mechanism. The shock absorbing mechanism uses a carbon fiber composite material layer and the airbag to detect the pressure through a pressure sensor to prevent the airbag from rupturing. The filtering mechanism automatically replaces the filter plate through electromagnetic plates and timers, preventing blockage and extending service life.
Effectively absorbs the impact and vibration generated by piston movement, improving the operating efficiency and service life of the equipment. By controlling the inflation pressure of the airbag, the service life of the airbag is extended. At the same time, the design of automatic filter plate replacement improves the filter effect and extends the service life of the filter.
