Multi-channel flow control system

Abstract

This system provides a multi-channel flow control system that prevents damage to the oil pump from air pumping and prevents the oil retention space from overflowing due to excessive accumulation of hydraulic oil. [Solution] The multi-channel flow control system is applied to the oil return control of a hydrostatic rotary mechanism and includes an angle sensor module, a signal processing module, and a flow control module. The hydrostatic rotary mechanism has an oil holding space for hydraulic oil, and the hydrostatic rotary mechanism vibrates around a first rotation axis, causing the oil holding space and the angle sensor module to vibrate synchronously, thereby relatively raising and lowering the horizontal height of the oil drain holes on both sides of the oil holding space. The flow control module has multiple conduits connected to the oil drain holes and the return pipe, with valves provided in each conduit. The angle sensor module detects the vibration angle of the hydrostatic rotary mechanism and generates a detection signal, and the signal processing module receives the detection signal and generates a control signal to control the valve, thereby controlling the amount of hydraulic oil flowing from the oil holding space to the return pipe through each oil drain hole.
