Mechanical hydraulic precision flow control system and control method

Abstract

The invention provides a mechanical hydraulic precision flow control system and control method. The mechanical hydraulic precision flow control system and control method are suitable for oil injectionequipment. The mechanical hydraulic precision flow control system comprises an oil way block, a one-way valve, an overflow valve, a proportional pressure reducing valve, an electromagnetic reversingvalve, a throttling valve, a pressure gauge, a pressure sensor, a flow meter and an electromagnetic on-off valve, wherein an output port of conveying equipment communicates with an inlet of the systemthrough a pipeline; and oil liquid flows in from the inlet of the system and flows out from an outlet after being adjusted by the precision flow control system. According to the mechanical hydraulicprecision flow control system and control method, the oil liquid is controlled through the system, the pressure sensor and a hydraulic control system are matched so that the oil liquid has stable workpressure, the flow meter and the hydraulic control system are matched so that the oil liquid has accurate flow and flow speed, and the electromagnetic on-off valve can rapidly control opening and closing of an oil way. In the technical scheme, when the pressure and flow of the oil liquid in the pipeline change, real-time control can be achieved, corresponding pressure, flow and flow speed adjustment is made, and the stable output requirement is met.

Description

technical field [0001] The invention relates to the field of mechanical hydraulic control, in particular to a precision flow control system and control method for mechanical hydraulic pressure. Background technique [0002] Oil injection equipment is an important functional equipment in industrial production, but in high-demand occasions, there are high requirements for the stability of oil delivery, such as stable pressure or accurate flow, due to the input source of oil in most cases They are relatively common conveying equipment, which cannot stably control the pressure or flow, so they cannot meet the requirements of stable output. Contents of the invention [0003] In order to solve the above problems. The invention provides a precision flow control system and control method for mechanical hydraulics, which are suitable for oil injection equipment, including oil circuit blocks, check valves, overflow valves, proportional pressure reducing valves, electromagnetic reve...
