The hydraulic power unit has two modes: remote control (REMOTE) and local control (LOCAL). [4] The closed-loop control system integrates HPU, motion controller and servo proportional valve, which can realize arbitrary curve setting, high frequency response and high precision motion control.
The micro hydraulic power unit adopts a silent motor and noise reduction oil tank design, and the operating noise can be as low as 42 decibels. The high precision servo hydraulic valve flow control accuracy can reach ±0.1 L/min, and with the feedback of displacement sensor, the positioning error of the robotic arm can be less than 0.1 mm.
The built-in integrated design integrates the motor, oil pump and other components into the oil tank to reduce noise and connection complexity. Bosch Rexroth innoCube highly integrates mechanical, electrical and hydraulic systems.
Intelligent interconnection technology realizes status monitoring through Ethernet interface. Energy saving technology adopts servo synchronous motor and frequency conversion drive, which intelligently adjusts the speed according to demand, and can achieve energy saving effect of up to 80%.
Status monitoring monitors the health indicators such as the volumetric efficiency of the main pump in real time through pressure sensor and mathematical model. The online monitoring and intelligent diagnosis system can improve the intelligence level of the system.
