针对大功率液压马达调速系统动态响应慢、调速精度低、低速稳定性差、加减速平稳性差,难以满足过程调速特性、驱动与制动协同性差等问题,设计一种补油式液压马达阀泵并联分时变结构控制调速系统,介绍该系统各回路构成与工作原理。该系统的应用可以有效地提高设备运行可靠性,提高生产效率,促进安全生产,具有显著的经济效益和社会效益。
Aimed at the problems of slow response, low speed regulation, poor stability at low speed, poor acceleration and deceleration stability, difficult to meet the characteristics of process speed regulation and poor coordination between driving and braking, aiming at the problems of high speed hydraulic motor speed regulation system, Valve pump parallel time-varying structure control speed control system, describes the system of the circuit structure and working principle. The application of the system can effectively improve equipment reliability, improve production efficiency and promote safe production, with significant economic and social benefits.
