Multifunctional expandable energy-saving hydraulic pressure integrated circuit

Abstract

The invention relates to a multifunctional expandable energy-saving hydraulic pressure integrated circuit, which is composed of two sets of hydraulic pipelines arranged perpendicular to each other and an electronic control unit, wherein each set of hydraulic pipelines is composed of n parallel hydraulic pipelines (n is equal to or greater than 2) at least; the two sets of hydraulic pipelines belong to different layers and are overlapped; the hydraulic pipelines arranged longitudinally are referred to as longitudes; the hydraulic pipelines arranged latitudinally are referred to as latitudes; the longitudes intersect and are perpendicular to the latitudes; the longitudinal hydraulic pipelines are connected with pressure sources; the latitudinal hydraulic pipelines are connected with actuators; longitudinal hydraulic pipelines and latitudinal hydraulic pipelines are connected at each intersection point via a two-way cartridge valve; so long as the cartridge valve at each intersection point is opened, the connection of one longitudinal hydraulic pipeline and one latitudinal hydraulic pipeline can be realized; the pressure sources and the two-way cartridge valve are controlled by the electronic control unit. According to the multifunctional expandable energy-saving hydraulic pressure integrated circuit, different circuits can be formed by connecting different latitudes and longitudes by means of opening or closing the two-way cartridge valves in the system, so that real-time expansion of load and oil sources in the system can be realized; through changing cartridge valve components and matching manner of multiple cartridge valves, the circuit has multiple functions.

Problems solved by technology

[0003] However, the hydraulic circuit in the current hydraulic system has a common problem, that is, the function of the hydraulic circuit is single, or the function of the hydraulic circuit is only suitable for a specific function under specific requirements; there is also the irreversibility of the hydraulic circuit. Once the hydraulic circuit is designed, The function of the hydraulic circuit cannot be changed

Secondly, it is also a common problem in the hydraulic system, that is, the inevitable problem of low efficiency in hydraulic transmission.

Especially for the multi-execution load hydraulic control system, the power source and the multiple execution load conditions cannot be matched one by one, resulting in huge energy loss

Thirdly, at present, the degree of integration of the hydraulic system circuit is not high, the hydraulic system is complex, and it takes up a lot of space, which has great limitations for mobile hydraulic devices.

Finally, the current hydraulic system circuit has no scalability and poor redundancy. Once it is completed or a bad point appears, it will not only take time and effort to modify it, but also cause huge economic losses to the enterprise.
