Abstract

The invention provides a multifunctional comprehensive experimental platform device which comprises an alternate current servo motor, a two-way variable pump, an oil supplementing device, safety valves, lock valves, stop valves, a hydraulic cylinder, load devices, a hydraulic motor, a roller, a proportional reversing valve, an overflow valve, a metering pump, a common motor, a flow sensor, a pressure sensor and a controller, wherein a direct-driven oil source is composed of the alternate current servo motor and the two-way variable pump, a valve-controlled oil source is composed of the common motor, the metering pump and the proportional reversing valve, and the rotating speed and rotating direction of the servo motor, and the size and direction of the valve port of the proportional reversing valve are changed according to instructions of the controller, so that the starting, speed changing, reversing and stopping of the hydraulic cylinder or the hydraulic motor are realized. According to the multifunctional comprehensive experimental platform device, the direct-driven oil source and the valve-controlled oil source are connected in parallel to the hydraulic cylinder or the hydraulic motor, so that a valve control experiment, a direct-driven pump-control experiment, and a control experiment combining the direct-driven control with the valve control can be carried out.

Description

technical field [0001] The invention belongs to the technical field of electro-hydraulic servo, and in particular relates to a multifunctional comprehensive experiment platform device. Background technique [0002] Energy saving and emission reduction is a concept advocated in the industrial field today. Industrial equipment, especially large-scale industrial equipment, requires high-power drive equipment to ensure stable operation. The hydraulic system is widely used in the industrial field because of its advantages of stability, high power, high control precision and high efficiency. [0003] The traditional electro-hydraulic servo control system is divided into two categories: volume control and valve control throttling control according to the different hydraulic control components. Volume control is to adjust the output of the actuator by changing the displacement of the pump or the motor. The speed of the driving motor is constant. The advantage is that there is no t...
