Electro-hydraulic servo drive
  • Brick press servo system

    The ceramic brick press is a high-tech equipment integrating machinery, electricity, hydraulic pressure and automatic control, and it is also a high energy consumption device. The brick press is driven by a high-power asynchronous motor to drive the oil pump, and a plunger high-pressure oil pump is often used as a necessary part of the equipment. The hydraulic source can generate a certain pressure and a certain flow of hydraulic pressure, and complete each required action under the condition of automatic control. When the oil pump is turned on, the oil cylinder rapidly descends, low pressure pressurization, low pressure amplitude, medium pressure pressurization, high pressure pressurization, high pressure hold, slow rise, rapid rise and other actions, each action uses PC to control the switch of the solenoid valve, according to different Process to set low, medium and high pressure to meet the requirements of the product. In terms of oil circuit design, the motor drives the oil pump to provide constant flow and pressure at a constant speed. The actual action flow is far from reaching the maximum flow of the oil pump. The excess hydraulic oil flows back through the relief valve. This process is called high pressure section. flow. The high-pressure throttling efficiency is generally 30% to 50%, and the energy loss is as high as 40% to 60%. At the same time, due to the long-term full-speed circulation of the hydraulic oil, the violent friction with the hydraulic parts and mechanical parts will cause the oil temperature to be too high and the noise to be high, which will affect the life of the brick machine system.

    Servo energy saving: After the servo transformation of our company, the power consumption of the motor can be saved by more than 50%; the injection molding machine works 24 hours a day and 28 days a month;

  • Aluminum profile extrusion machine servo system

    Aluminum profile extrusion machine is a machine that extrudes aluminum alloy rods into various specifications of profiles. The process parameters such as extrusion coefficient, extrusion speed and other process parameters need dynamic changes in pressure and flow at each stage, and there is overflow phenomenon in the high-pressure extrusion process under production conditions, resulting in waste of electric energy. The industry's demand for high-performance power systems is put forward by a well-known large-scale aluminum extrusion press manufacturer in China, which promotes the reduction of production costs and advocates energy conservation and environmental protection in the industry. With the assistance of machinery manufacturing enterprises, our company has launched an industry-leading extrusion press servo. Electric motor hydraulic drive system. This system mainly adopts servo driver, servo motor, combined oil pump and closed-loop control of pressure, speed and current. The servo system matches the oil pump to be controlled separately according to the action sequence, the oil circuit closes the pressure relief valve, uses the pressure feedback of the servo itself to adjust the oil pressure change, adjusts the actual working pressure according to the set pressure, and reduces energy loss; the main cylinder extrusion adopts the column The plug oil pump is independently controlled, and the output power changes with the load. It stops when it is not working, and there is no waste of excess energy. A fully closed-loop servo control system with low energy consumption, high efficiency and high precision is achieved.
