Abstract

The invention provides a dual-motor oil source control system and method, which solve the technical problems of low efficiency and inconvenient layout of the existing oil source control. The system includes: an upper computer, which is used to form the initial control data of the motor driver according to the demand, receive the hydraulic state signal of the output pipeline of the parallel quantitative pump, form the state control data and send the motor driver, and establish the closed-loop control of the parallel quantitative pump; the main motor driver, It is used to form the real-time control parameters of the main pump servo motor according to the state control data; the main pump servo motor is used to adjust the torque and speed output mechanical energy according to the real-time control parameters of the main pump; the main pump is used to receive mechanical energy and convert the oil source medium The connecting pipeline of the hydraulic system flows according to the corresponding pressure and flow rate; it also includes the auxiliary motor driver, the auxiliary pump servo motor and the auxiliary pump. The system composition is conducive to the flexibility of system layout. The variable speed control of the high-precision servo motor can be used to realize the flow change control, which is better than the control effect of the single variable pump.

Description

technical field [0001] The invention relates to the technical field of hydraulic power, in particular to a dual-motor oil source control system and control method. Background technique [0002] In the prior art, variable flow and variable pressure oil source designs are often required in hydraulic applications. In order to ensure the maximum output efficiency, the total power and power distribution characteristics must be considered during the oil source design process. Traditional oil source designs often Using the constant speed output of the three-phase AC motor, the variable flow function is realized through the variable flow pump. When the load requires a small flow, this kind of design scheme has a lot of power waste, and the reliability of the variable flow pump is relatively poor. At the same time, due to the relatively large size of the traditional three-phase AC motor, there are many limiting factors in some use environments with limited layout space. Contents of...
