Product Description

Ningbo Youzhi Machinery Technology Co.,is a high-tech enterprise integrating R&D, production, and domestic foreign trade. "Technology Creativity in the Future" is the core competitiveness that creates the miracle of the industry. The company attaches great importance to the investment of scientific research and the development and cultivation of talents. The energy-saving hydraulic station can have built-in PID control and no-speed feedback vector control compared to the conventional inverter, so it has better control characteristics;  The company obtained a number of "Utility Model Patent Certificates" in 2015

innovation of the energy-saving hydraulic station

Energy-saving hydraulic station working principle: When the control valve is opened, the hydraulic circuit starts to work, the pressure value in the plunger pump drops, the sensor senses that the pressure drops below the setting, the controller immediately gives instructions to increase the motor speed to protect Hydraulic return to normal work.The intelligent hydraulic station can set the hydraulic station to supply only one machine tool, so that a set of information is exported to the machine tool control system for the information sets of the hydraulic clamping signal, the gas detection signal, the oil level signal, the motor temperature signal, and the like. Kinds of CNC control systems. 

Main Features for hydraulic power unit

Hydraulic energy-saving equipment through the flow control mode, to achieve one with two (a hydraulic drive two machine tools), according to the pressure signal of the pressure transmitter to go back to the servo drive, the servo drive further through the host computer to set the pressure signal and The feedback signal is compared to control the servo motor to achieve system stability through the value of PDI output. The servo driver sets different pressures according to different processes, maximizes the use of energy, and achieves energy conservation.

The variable displacement pump of ordinary hydraulic station has throttling loss in the flow control state, so the speed control loop of the open-loop variable pump is the volume throttling speed control loop. The external motor always drives the pump to rotate at the rated speed, and the mechanical loss has been maximum.

The hydraulic system is mainly composed of the following components: a device that controls and adjusts the pressure, flow, and direction of flow of the fluid in the hydraulic system diagram. Such as overflow valves, throttle valves, reversing valves, etc.; auxiliary devices to eliminate other than the above three devices, such as fuel tanks, filters, water filters, oil mist, accumulators, etc., which guarantee hydraulic pressure The system works reliably and stably; the fluid that drives the energy of the medium, hydraulic oil or compressed air.
