Problems solved by technology
For the output of the digital flow control unit, the traditional control method has problems such as discontinuous flow output, large amount of calculation, too large step size of the flow step, and single control mode, which limits the output accuracy of the digital flow control unit and affects the hydraulic pressure of the digital valve group. The application in the system is a problem that urgently needs to be solved by those skilled in the art

The invention discloses a digital valve group integrated unit configuration and a control method. The digital valve group integrated unit configuration comprises a bottom plate valve block, a plurality of switch valves, a coil and a measurement and control assembly, four digital flow control unit valve blocks are uniformly distributed above the bottom plate valve block, and four groups of two-layer oil ducts corresponding to the digital flow control unit valve blocks are arranged in the bottom plate valve block, the two-layer oil ducts communicate through a plurality of branches, and a plurality of switch valves which are distributed at equal intervals and used for controlling the branches are arranged on the upper sides of the digital flow control unit valve blocks. Small-flow electromagnetic switch valves are connected in parallel, different numbers of switch valves are combined, a configuration mode of any coding is obtained, and discrete output of stepped flow is achieved. A closed-loop control method of PCM, PWM and combination thereof can be adopted, continuous control is approximately achieved through the digital switch combination, high-precision control is guaranteed, and the digital valve group integrated unit configuration is simple in control, fast in operation, high in output precision and wide in application range.
Description
technical field [0001] The invention relates to the technical field of hydraulic switch control, in particular to a digital valve group integrated unit configuration and control method. Background technique [0002] As a key component of electro-hydraulic digital control technology, small-flow electromagnetic switching valves have the advantages of simple structure, low cost, high response, low pressure loss, strong anti-pollution ability and high reliability, etc., and have gradually been widely used in the field of electro-hydraulic digital control technology. , On-off valves are individually controlled through digital signals, which are easy to integrate with micro-sensing technology and modern communication technology, and can realize editable control, interactive connection of components and systems, and real-time collection and processing of system working conditions. However, its small flow characteristics cannot meet the requirements of driving large loads. [0003]...
