Abstract

The invention relates to an energy-saving hydraulic system and an automatic control system thereof, and belongs to the hydraulic technical field. The energy-saving hydraulic system comprises a hydraulic system body and the control system. The hydraulic system body is composed of an oil tank, an efficient and energy saving motor, a constant-power electric control proportional variable pump, a cartridge valve set and a hydraulic oil cylinder or a hydraulic motor. The control system is composed of a computer, a communication module, a touch screen, a power module, a CPU module, an input and output module, a relay module, a proportional amplifier, a displacement sensor and a motor soft starter. The energy-saving hydraulic system and the automatic control system of the energy-saving hydraulic system have the advantages that the efficiency is high and energy is saved; the energy-saving hydraulic system can have access to the internet to form a production line; remote control can be conducted through the internet; the working pressure, the working speed and the working displacement can be controlled accurately; the touch screen can display and control equipment states, and operation is convenient; operation is safe and stable, and the hydraulic system can be widely applied to the hydraulic machine industry and high-grade, precise and advanced equipment with hydraulic pressure serving as motive power such as large-size hydraulic equipment.

Description

technical field [0001] The invention relates to a technical solution of a hydraulic system and its control system, in particular to a technical solution of an energy-saving hydraulic system and its automatic control system, and belongs to the field of hydraulic technology. Background technique [0002] At present, the hydraulic systems of hydraulic presses and large-scale hydraulic equipment on the market are mostly dual-power hydraulic systems composed of high-pressure small-flow pump sets and low-pressure large-flow pump sets. The way of flow, the power loss in the control process is large; the control system configuration is low; online production cannot be realized; remote control is not possible; the control accuracy of the working pressure, speed and displacement of the equipment is low. Contents of the invention [0003] Purpose of the present invention: [0004] To solve the technical problems of the hydraulic pump drive motor in the existing hydraulic system, whi...
